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?

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!

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!

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...

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.

Also Begone; are you running a bpu TT with the w58 also? how is your gearbox holding up?

Cheers

Gene
Nope, I have an SP Built Auto w/3800 Stall. And man with those JDM Twins...Instant Spool. But now I'm Single with a TC61. Loving it. I'm still running on my Stock 440cc Injectors on this single. I'm only running around 15-16 psi. I got larger injectors coming shortly - then the boost goes up, up, up!

True, true on the Sump issue...

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.

So on the MAP sensor, where is it located? Did you get it with the motor or did you n eed to buy it seperate? Also, how does it plug into the US harness?
Both usdm and jspec motors come with map sensors located on the intake manifold. The us harness already has a plug for the map so it just plugs right in without any problems.

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.
