I've yet to see one. For a small displacement engine & a relitively heavy car, turbocharging will give the best results. Are going to drive it on the streets using pump gas? Those cams & the lightweight flywheel will certainly increase noise, vibration & harshness. Since it hasn't been done, no one knows the best route to an all motor Supra. Remember, BMW did everything they could for the I6 M3 & ended up going 4.4 V8. Wringing out horespower to compete with larger displacement cars created a hoghly specialized powerplant that was most likely prohibitvely expensive to produce.
If you keep reading & reviewing others experiences on this forum, you'll find minimal improvement from bolt-ons. You will not be competitive vs LS1's, Mustangs, M3's or newer GT cars. We have old technology, a smaller engine (3.0 vs 3.5), no variable induction for wide range power with an engine that falls off @ 5k rpms. Keep it clean, enjoy the handling, go turbo if/when you can afford it. Maybe autocross?

 

Gonna need extractors and exhaust + cold air intake.

 

idk how much hp it will yield but my bone stock na put 213 to the wheels on a mustang dyno if that helps.

 

i dont wannt burst your bubble...but your bonestock na isnt making 213 rwhp, these cars make 220 hp at the crank AT BEST, probably not even that once the rings wear out as you are approaching higher mileage. a stock NA 5spd is probably making in the region of 160-170 rwhp... Supragreg on here had an NA auto with an SAFC, a tune, and an exhaust, his car made somewhere in the 180's i believe? i think it made higher than most NA guys manage to make w/out doing SERIOUS mods to the GE.... so the guy that did your dyno over-corrected your results by WAYYYY too much. they can give you just about any result you want to see by punching in certain correction factors into the system... but in reality the car isnt making the hp...

but anyways. i just wanted to correct the BASE LINE hp that you will be starting at with an NA engine.

as you dont want to hear any Turbo talk in here im going to leave now (my NA-t is making about 520hp at the crank, more than double the stock NA) but just know that you will be lucky to see 320rwhp in a built NA supra, unless ofcourse you have A LOTTTT of money to throw at it

:kiss: good luck on the build :kiss:

 

ive already got a full 3" stainless 1 piece mandrel bent exhaust and extractors. and as for the engine falling off at 5k rpm the cams will help. i have been researching this for 2 years and have quite alot of data to go with plans and fully intend to build this engine. as vreaux728645 said it hasnt really been done before so i am keen to see what is possible.

 

what ever you say man i have the printout to prove it and many saw it at the tristate meet. but anyway i hink you should try it

 

kid... are you really going to tell me you HONESTLY believe that your car, in BONE STOCK condition, made more than any MODDED NA supra on the ENTIRE FORUM??

i just explained to you that a dyno operator can make the graph read just about ANY hp numbers he wants by putting in elevation corrections, etc into the program... but hell, if you really are 15 it would be pointless for me to try to prove your piece of paper wrong with common sense, better knowledge on the subject and intelligence... but if you ever are in the area please do bring the bone stock na to our state of the art Zmax drag way here in charlotte and we'll see how it puts up against my brothers NA 5sp with a few mods (and i can tell you his car isnt making ANYWHERE NEAR 220 rwhp)

 

oh and please dont forget that you are starting with probably HALF the displacement of the bigger engines that REALLY benefit from NA build ups.... but you probably dont want to hear that.

my thought on the subject is this : if you are doing this just to be able to say that you have done it, and be the first down this road (that i can guarantee no one else will follow) than by all means im with you on this. or even if you are building a race application that can use the quicker response, or have regulations to follow as far as not being able to mod the engine with turbos, etc. im with you on that as well.

but if you think you are going to build an engine that yields some sort of AMAZING hp........i hope im wrong and you can prove that i am wrong with the GE's capability... but i really cant see that happening.



best of luck

 

ohh im not insulting your intelegence just saying cuss everyone elses cars were makin soot on hp to previouse runs at other places. maybe mines a facrory freak (60k) or has something done to it idk. and yeah im 15 but i know my way around cars and motors

No, you don't.

 

There is no way your bone stock na put 213 rwhp down i have to call you out on that sop you saying your car rated at 210bhp put down 213rwhp which is ver 250bhp . i dont care what you saw or what the graph say's its impossible. I put down 222.5rwhp in my auto na supra with a ton of custom work done to it minus building the motor. A bone stock na supra will put down 160-170rwhp bottomline. Damn newbies gving out false info.

 

ok your the kinda person im trying to reach in this thread. what 'custom work' have you done to achieve this?? im happy to discuss this further in pm if you dont wish to make it public.


and no i am not expecting HUGE hp figures, i just want to see what the engine is capable of. and that includes staying at 3 litres. i wont be adding a stroker kit to it. as far as i am concerned the average is around the 160rwhp mark for a na 2jzge. and unless you have done anything serious to it you are talking shit if you think you have any more than that.

when you break 160rwhp down thats just over 53rwhp per litre which is rather dissappointing, especially from an engine as well designed as a 2jz. so my goal it to make it at least to the 100rwhp mark per litre which is generally concidered to be achievable with any engine...... with money and time.

 

He has done everything he can think of. Likewise I met a member who even tried some ignition item-he's n/a-T now. Review Xdreemer's mods/results, see what was most significannt & then get back to cams, pistons, porting & what not. We have an under developed powertrain by todays standards & little aftermarket.

I'm going out in mine right now. Guess its time to get revved on!:rofl:

 

the 2jz is a very well engineered TURBO application motor... there is no ifs or buts about it...

but like i said, im all for innovation

 

we shall see then

 

ahh lol i was goona point this thread in your direction carmsbody till i seen it was you who made the thread

if iwantablackrz made 200rwhp im sure with cams and head work you'll make a decent number ... is it going to be ready for the qldsc dyno day ??

 

I made 175.8rwhp on a 95 auto with 7 months no oil change, crap load of leaks and etc lol. All I have is a K&N drop in filter, Apexi N1 exhaust, and iridium plugs if those even matter lol. It was done on a dynopack. I actually think it read higher than what I should have gotten.

 

I definently think you can make 100whp per liter with a 2jzge. Honda guys with k20's have made 270whp. Sure there isn't that much torque to go along with it, but honda engines are meant to rev. I'd suggest a bigger throttle body, and maybe a intake manifold with larger diameter and shorter runners. Good Luck! I plan on doing a stock rebuild on my 7mge plus a 2 stage zex kit. Hoping for 300whp and a lot of torque for my heavy mk3.

 

if your going to build a complete NA, have you looked into VVTi? this will help your torque? just thinking any little bit will help...

 

you may need to add some type of ems to your parts list. something tells me your engine idea just may not run very well on the stock computer.
just my 2 cents

 

Gfallon,

Do you know any Taylor's down there in the Brandon area? A lot of my folks live down that way!

On another note, please tell me that someone is making ~250 HP with a NA 2JZ. I am making nearly 180 HP with an old 5M MKII Supra. Also, I am looking to make an assault on the 200HP mark once I install my stand-alone and remove the OEM AFM. Internally the engine is bone stock, save a set of aftermarket cams. The engine will be replaced by a 2JZGE (sitting in the garage), after my next dyno.

Punching the numbers, the 2JZ has 0.2 more liters and 10% more valve area than the 5M. It has to have legitimate 250HP potential...

Regards,

Carlos

 

well i have not heard of any thing more than 220whp (on a dynojet i am sure). when i had my aem tuned at speed for sale it did 215whp on a mustang dyno @ 7,300rpm. but i did not think to ask them to get me a print out. i have added a few small things since then but don't thing they will effect my peak hp, mostly low and mid range power. which is what i need at the track anyway. so if your 250hp is crank hp then yes you can get it. i think you have a loss of 40hp from crank to wheels, so that would put me with 255hp, and the mustang dyno is known for giving out low numbers. if you are looking for 250whp i would say it is possible, but you may need a fully built bottom end to hit it. (not just the built head)

 

Gfallon,

I have to believe that 250 RWHP with a near stock 2JZ is easily accomplished. Not necessarily with bolt ons, but with improved breathing mods. I may be pipe dreaming, but I have taken an 86 2.8L 5MGE, advertised at 160 BHP, and am now making ~180 RWHP with it. And I fully expect that number to be right at 200RWHP after the AFM has been removed. All this on a completely stock bottom end...

Well, I guess I will find out soon enough once the 2JZ goes in!

Regards,

Carlos

 

thanks for all your input guys. been a while since ive been here.

i am currently building this engine now, have teamed up with a old school engine builder and we are making progress on this.

with my last engine (before i blew it) i was makin just over 200rwhp with just breathing mods.

when i tuned it we lost the motor. oh well.

cant wait to see the results of the new na engine.

 

there was a magazine article posted on clublexus awhile back about a supra with a built na setup making a little over 300 rwhp i belive... but the amount of work/money invested was more than a 3.4l stroker and a good turbo kit would run you... so it seemed pretty ridiculous to me.

 

knife edge the crank, go dry sump, oil scrapers, fatty injectors, full valvetrain, full porting. I don't know how fun it will be to drive in a mk4, but a built n/a 2j in an older toyota would be a shitload of fun.

 

How much do you think all this would run a person?

 

why has nitrous not been mentioned?

i met this guy with a fully built n/a 7m with nitrous claiming almost 400hp.
i rode in his car without the nitrous and it was better than a stock 7mgte for sure.

 

a true n/a does not run nos.

i have spent well over 10grand and still have the stock block

 

I think the the fastest non turbo horsepower with all mods that can be done on a 1993.5-1995 Toyota Supra non-turbo automatic was xdreamers. He used to be on here or still is but he ended up selling his car for a Subaru wrx or sti. I believe he made approximately 222rwhp on his na automatic white supra. The mods he did, I don't know all of it but it can probably be seen on his sig a while back. He definitely went the na all motor route because he thought that he could break the barriers of making and beat other cars with being all motor.
