Thats right...i finally finished!

It first started with sourcing the motor. I posted up and got a response from a few people, Sherbaz was the first guy. I began talking with him and finding out information and trying to see what he had in stock. Sherbaz was a great guy to deal with. He talked to me all about how he can help me out and what not finding a motor that would fit my needs. He told me he had a JSPEC True Supra Motor. So i decided rather than worrying about swapping water pumps and etc. I just decided to go with that motor. It came with a auto tranny, ECU, Igniter, and Harness. Just like any other motor you see someone is selling, a compelete package ready for a swap basically. Of course like any other swap you need an oil pan etc etc etc. After i put a down payment Sherbaz sent me a video of the motor starting on the ground. After that i was satisfied with it and proceeded with the rest of the payment and then followed through with shipping. Shipping was great and fast. I was suprised and happy with the motor when i received it. It came with an automatic tranny, but i used the 5spd off my N/A motor instead. I was going to a 6sp swap but i didnt have the money at the time after i got the motor. I proceeded with the swap though and everything was a breeze. Used the 5spd A/C and PS. The Swap went smoothly in and out.

****
I used a US Harness instead of the JSPEC harness. I stayed with the JSPEC Injectors, JSPEC ECU, and JSPEC Igniter. I got a MAF sensor just in case i would run into problems with running the car. After i swapped the motor i was worried it wasn't going to run. I simply swapped the Injector clips off the JSPEC harness onto the US Harness. And of course the other connectors that wouldn't work. Such as oil pressure connector, and etc. The car started right up! I was very happy. I also stayed with the JDM turbos. The car is running like a champ though. Not until today i took off the MAF connector and the car runs without it. Even better! So it runs on the MAP sensor.

I will put up pictures later with the swap and everything. Ive alrady run the car numerous times against cars such as a Z06, Upgraded Talon TSi, Etc. Car is running great and im running upgraded parts of course.

Upgraded Parts list consists of:
HKS Type-R FMIC
HKS Pipe Fitment kit for stock turbos
HKS Turbo Timer
HKS EVC w/ Display
HKS DLI
HKS Racing Ti (100mm)
Speedforsale.com ETTC Switch
Takata Harness
Recaro EVO VIII Seats
Ebay Downpipe (custom fab to fit to stock JSPEC Turbos)
TRD Tach
Tial BOV

Ive been through the whole swap and everything, if anyone has any questions or comments regarding my swap and things ive done please dont hesitate to PM me.

I would like to thank the following people and shops for hookin it up!

***Pictures from the Swap***

Here are the pictures from the swap, Its such a releif that the car is running finally though, its great to have her back on the road. The swap didnt take me long, there was a good amount of time taken up waiting for small things i forgot, but of course this is going to happen unless you know for sure. Now i know! Definatley going to this more and more in the future it was a blast and i had a great time doing it! Took around 2-3 weeks im guessing cant really remember i stayed up for like 3-4 nights straight at some times working on small things, but i mainly worked weekends.

NOW FOR THE PICS!!


N/A motor ready to come out!


N/A motor out and on the ground resting....notice the leaky valve cover's....sooo thats where all my oil went...


Engine Bay Shot after the motor was out and some cleaning action was done!


Stand back and enjoy...maybe a cigarette break?


Stock Toyota 5-spd Flywheel installed


TT Motor Prepped clutch installed ready to be dropped in!


TT Motor in, lineing up motor mounts **BTW JSPEC Supra Motor Mounts fit perfect to US Chasis**


Another shot of the TT motor going in...


Intercooler pipping installed


HKS Type-R FMIC Installed


Intake installed and Fluidyne Radiator installed


Tial BOV Welded on to intake pipe


My J-spec Supra Motor when i first got it from Sherbaz!

It wasn't a TRUE Supra J-Spec engine if you had to replace the Oil Pans...Just FYI.

I've gone through the same swap. Congrats though, that's awesome you got everything working. Everything sounds perfect. I only really have one question.

Did you have to change alot of ECU Pinouts to make the US Harness connect to the J-spec ECU? If so, do you remember and keep record of what those were? It would be a HUGE Help to the supra community and anyone wanting to go forward with this type of project. Good job man!

Drew
I mean the oil pan was damaged during shipping....dented in...smashed....oil pan was exactley the same i just wasn't going to take the risk of having a dented oil pan and throwing my oil pressure off. So it was a true supra motor.

But the harness was a US harness, the ecu is Jspec, the harness plugged perfectly up to the jspec ecu, i didnt have any problems...the only thing that doesn't work is the traction computer.

yeah...seems like the shipping company or when they put the motor on the pallet they just dropped it...or it was dmged during shipping...or just all the weight from the top crushing that pan....but no biggie...i replaced it to be safe...

yeah tell me about it, my friend and i are going to try and do a SC300 i think...we're not sure, but man the swap was alot of fun, i enjoyed it alot.

Oil pan is easy fix.. Rubber hammer is the trick.. These motors are shipped from japan etc and then come to me etc etc.. I promise a good strong motor and he got that..

Sherbaz

oh yeah! this thing is running like a champ! sherbaz promised me and what do you know its fine! messing around with corvette z06's on the highway is always a blast :p especially on stock twins :drool:

Great work, congrats on the swap Ben. So you're using the stock n/a w58 5speed? how does it feel behind a bpu engine?
Gene
Gene, the w58 5spd feels fine behind the bpu engine, it obviously has very short gearing but by far does this thing haul ass, the gearing is so short so your at 140 before you know it! With these turbos too they spool so damn quick (stock jdm's) and the gearing i spin tires in 1st, 2nd, and almost all the way to the top of 3rd. The w58 i dont think can handle hard shifts, because sometimes when i was doing drive bys for a friend of mine for some video footage, going into 3rd real fast i could definatley hear grinding and feal it on my hand....but it goes into gear, u know how some trannys are built to withstand the power and fast shifts, but i dont beleive this tranny can do it....it would need some work probably...but definatley worth it....its a fun gear box though!

Nice swap ben! Hope to see it at a meet around here so i can check it out.
Thanks man! yeah hopefully we can set something up soon, i was talking with hung and bao and we were thinking of setting up a barbecue or something...ill post something in the regional definatley!


Urban Customs said:
hey great swap. im actually doing the same thing right now. what clutch did you get for your 5 spd. i got the max pressure plate w/6 puck disk rps.

when you swapped over from auto to stick did you buy the 6spd belt tensioner?

so you basically bought the jdm motor and bought a 6 spd harness and re used the jdm ingiter. but since you went with jdm motor did you use the efi resistor pack with the us harness?
I used the RPS Max Clutch w/ Street Disc. I used the auto tensioner, i did not use the EFI resistor pack i actually found something from a member on here who forwared me to look into these. i actually found them in junk yards. They work great! i will get a picture up of them, i have one spare one if you plan to stick with JDM injectors btw!

supdawg79 said:
So how is the 5-speed holding up with the new motor? Did you change the reverse connector on the 6-speed harness that controls the reverse light with the old 5-speed harness connector?

5spd is holding up great, im throwing whatever i can at it, launched it hard a few times, but i dont have the tires to support the power at the moment...shitty cobra something tires from the previous owners, but im going to be going with a rim and tire setup shortly hopefully if the funds are sufficient. But once i do that i will be testing the limits of the 5spd :p i will have a 6spd tranny shortly lined up for onec the 5spd goes and once it does the new clutch and flywheel will be for sale...

i have not changed the connector on the 6spd harness to the 5spd connector i didnt want to fuck with it since i was going to be going with a 6spd in a few months. I dont drive the car on a daily basis, its mainly my "weekend warrior" at the moment. Dont want to rack the miles up. But the reverse lights do not come on at the moment...

Urban Customs said:
hey ben. so let me get this straight. you went with us harness, us maf, jdm ecu, jdm turbos and injectors.

what i was planning on doing was us 6 spd harness, us auto ecu, us maf, us igniter, us efi resistor pack, jdm turbos, jdm injectors.

you think this will work?

Yes, but i later found out i did not need the MAF sensor...so i took it out...well in the process of taking it out. the JDM injectors wont work with the US ECU. The ECU will not know how to control them saying u would not need an EFI resistor pack either. They are different injectors, meaning you need a different computer. If you going to go that far and getting the EFI resistor pack and US ecu, you might as well upgrade the injectors to US injectors so you dont have to rip apart the new harness. But the way your saying, it will not work, you need the 550 US injectors.

Congrats on the swap. I also have a converted NA to JDM T67 with the 5 speed. Trans feels great so far i have been beating on it alot the last few weeks and no issues. Hope it holds for you, and keep those vettes and stangs on there toes.
thanks man, thats awsome how much power are you pushing through the tranny at the moment? i hope it holds for you as well. Yeah gotta love those vette owners :p damn jdm stock twins spool soo fast man!

Jimnen said:
Looks pretty good...how much did it set you back to go from na to JDM TT?
Im not exactley sure, i haven't added it up...but it wasn't that bad really, maybe ive just over excited and dont care at the moment, im just glad its running, and running strong at that!




BTW does anyone know when the JDM injectors max out at? :scratch: what psi and whp roughly? Just want to make sure she's running ok the way she is at WOT.

I'm proud of ya, son- nice work! :bigthumb:
Ranger498 said:
congrats on the job looks very nice.
thanks guys, it wouldnt have happened if i didnt hunt through and pick through the forums night and day before i started doing the swap.

Bodom said:
Man looks great. Im about to do a similar swap on my car. Im gonna pm you about some details..... cant wait.
Enjoy your new power!
I got your pm, i msged you back, hope everything goes well shoot me back a pm though.

JeremyBlackwell said:
Very nice work Ben! Congrats for being innovative!
Thanks Jeremy, btw the ETTC switch is amazing, i get some smoke at idle though now after the switch...any ideas? the switch is really nice though, thanks again man!


Yeah the car is running on the map sensor, car runs great though, i haven't had any problems with the way its running, boost fine, and pulls hard for stock twins. well compared to the n/a :p definatley pulls nice though. I still need to pull the maf sensor out of the intake pipe, i had to custom fab some stuff to get a K&N intake filter on there :p but it works, so now i have to undo all my work and take the maf out and put the filter back on...hopefully i wont have any problems...



ALSO does anyone know what PSI or WHP the stock JDM injectors start to max out at? And does anyone know if any companys make an MKIV specific catch can?

Thanks guys!

How are you turning up the boost? I didn't have a cat with my JDM and so I needed a restrictor plate so that I wouldn't over boost.

The 440's should be good to about 400hp. But I don't know if your Twins can handle that much boost. When I pulled my twins, they were tore up...very bad shape and looked like they were going to go out on me anytime. I was running around on 16-18 psi on those things though.
Well i have the HKS EVC w/ display i guess it would be the V? im not sure, but the EVC does not control the boost. I found some write ups on how people installed them. But im hitting upwards of like 117kpa-125kpa. These JDM twins are gunna be done soon if i keap this up. Im running around the same upwards of 16.8-17.8psi roughly. Im thinking of getting a cheap set of stock twins and swapping them, but i dont really want to do that....i kinda want to go with my big upgrade...but im not sure...money isn't coming off the trees at this moment....thanks for the help though, im glad ill be safe running that much boost on those injectors.

Great work Ben, where did you get that fender cover from ;)
hahaha, i love that thing, definatley came in handy, i mean i had to show it off in the pics :p thanks again Tony for the cover. Definatley saved some scratches and etc.

JeremyBlackwell said:
Glad you like it, thanks for the kind words!
Give me a shout and we'll discuss possible problems. The E-TTC switch isn't causing it, it just tricks the IACV and EGCV VSV's into opening early.
...sounds like your #2 turbo has some wear and oil is getting into either the intake side and being burned in the combustion chamber (pull an intercooler hose and check for any 'puddles' or excess oil) or oil is getting into the exhaust side and being burned immediately.
Yeah i beleive my #2 turbo is going. I think im getting the death wine....im not sure though i need to listen to the sound clip and verify from mkiv.com yeah im definatley going to pull my ic pipping tonight when i install the new TT PS resevoir since my "ghetto" rigged N/A resevoir is leaking like consitantly. Im almost positive these turbos are getting ready to take a crap on me though :rolleyes:

But the switch works great! Just wanted to clarify a few things though, When is the best time to turn it on and off? Because i remember reading you said not to turn it on at idle, ive tryed turning it on while boosting like 2-3 psi. Advice, recommendations, tips, hints? :p im just curious

Thanks,
Ben Y

Once your Turbos go out. Seriously think about going single. I too went single cause of the twins. I'm single now with a TC61, Ebay Manifold Heat Coated...well here's the link:

http://www.supraforums.com/forum/showthread.php?t=356751

But I'm running on my Stock JDM Injectors. Perfect AFR's. I'm only running 13-15 psi. ANd I need to get another Boost Controller cause my HKS Manual one won't hold it exactly. But it's a inexpensive way to go single, and then worry about the fuel later. Alot of the JDM/Euro guys were impressed. Everyone thinks that when you go single you HAVE to upgrade your fuel...not true. You just can't be running crazy boost. But my setup now feels alot stronger than the JDM Twins on 18 psi, and it spools very fast. Later.
How much power are you pushing begone on those JDM injectors? I know they are 440cc injectors. But i dynoed today and my A/F curve was rediculous. I made 405whp and 368lb/ft of torque but my A/F was lean and then @ 5k rpms it went safe (richened up) all the way till redline. Are you also running the 5spd on this kit? I was hitting upwards of like 127kpa on the dyno today according to my HKS EVC. Which btw wont control these jdm turbos if its life depended on it :p i mean its fun, but after the dyno today im a bit afraid to even drive/push the car. I beleive the way they tune these cars out of the factory in japan they come very lean for those strict emmisions laws. I dont see how they could do this, it would definatley melt a piston especially if you were doing top gear, low rpm's (2.5k rpms) WOT runs. Im a bit afraid at the moment to do anything else. I may just save up now since these turbos are going. I dont want to spend money on another set of stock twins, id rather upgrade, and upgrade big. I have big plans for the single but u know how every shoots for the stars (or the best). It might just be wishfull thinking but ive got a good amount of work ahead of me. Thats great though about your car, kinda wish you lived closer so i could take a look at it. Was your motor an aristo? What are you using to control the tunning? or are you just running the stock jspec ecu. What afr's are you seeing?

supdawg79 said:
Would I need to use the MAF if I were do this same exact swap, but using a USDM 6-spd ECU instead of the JDM ECU?
If you were using a USDM 6spd ECU that means you will need a MAF sensor to run the car. Dont be fooled, the JDM ecu does not require the maf sensor to run, it also comes with a few other goodies like no egr. Only downside is that if you have a jspec ecu, you have those damn ceramic coated wheels and they overboost and spool like crazy. Its fun, until they start to smoke...its rather embarissing...but if you have any other questions let me know!

there was a thread about this, lemme see if i can find it, but people were talking about keaping it on, and some of the disadvantage of it, such as it going out quicker or something along those lines. I dont have much experience with the aristo motor at the moment, but i do plan to get one one day and build it up and do alittle more R&D on it per say. check around the forums there was a thread not too long ago about this.

Ben Y

hope this helps

i haven't swapped the connectors, thats all you have to do to fix it, but i never got around to it, i figure since im going to swap the 6spd why cut the connector....

i did not replace the fuel hanger, i just swapped the fuel pump in and wired it up to a 12v source.
