Hi guys,
a guy from my neighbourhood recently bought a supra mk4 (it hasn't arrived yet) and claims its puttingout 400 wheel horse power on standard turbos and standard boost, is the supra capable of such figurea?

BPU, Basic performance upgrade, exhaust, filter, FCD, and boost controller, should give around 450-500bhp, which would be about 400rwhp.

do a websearch for BPU, and you will find plenty of info.

Thanks mate,
the guy doesn't have a boost controller that much i know for sure, i'm sure he has the exhaust filter etc, what quarter mile times are we looking at with this kind of power?

cheerz,
suhail

400rwhp would have you into low 12's i think... Depends on the dirver, conditions, tyres, etc.. lots of variables!!!

You'll have to be in something pretty special to beat it anyway........ IMO

Cheers,

No chance (unless your american ). BPU will see you with 400ish at the fly. If you have a UK with steel internals and ....really.... push it you might see 450.

500 on either jspec or uk turbos ain't gonna happen.

Pop over to www.mkivsupra.net and all your answers are over there!

That's what i was thinking mate, 500 plus bhp on standard turbo,boost etc is very high!! I'd get myself a supra tomorrow if it was that easy to get such power out of it, i was thinking maybe 400 at the fly which should be about it's limit with the standard turbo, any more opinions ??

ScoobyJawa

400bhp at the fly is pretty fast. Never lost to anything in my old one at BPU and that sort of power........

A Supra is very easy to get high power out of.

Standard JDM turbo's are good for no more than 1.2bar turbo pressure, plus injectors are smaller on a JDM. However, I have a JDM TT with FMIC, HKS Ecu, Full decat with Blitz Nur spec exhaust, HKS Ind. Kit, FCD and boost controller, and the car has run a 13.08 quarter mile.

Sorry I can't say it's xxxbhp, but as it's not been rolling roaded yet, so I wouldn't like to say. However, similiar spec Supra's run quarter mile times in the 12 second bracket, and with a kerb weight of around 1550kg you've got to be pushing over 350bhp at the wheels to achieve that.

Also, Supra's are known for being strong engines, and 600bhp on standard internals is not difficult.

Then why ain't you doing it?? I checked last night and you can get reasonable Supra's for around £14k. Surely another £4-6k would get you big turbo, injectors, ecu, zorst, etc giving you around 600 at the fly for 18-20k and enough performance to nail pretty much anything you'll come accross. Where is the catch!! Its like having a Cerbera, but faster and more reliable for the same £20k??

What have I missed here?

Hedge seeking missile Kenny? I couldn't fling a 1550kg 600 BHP RWD around in the wet on roads I know to anything like its potential, but I can fling about 90% of the same power to weight ratio around in something else in the pouring rain and enjoy it rather than arriving having been glad I survived. So far anyway

If you can handle it great

wrxtasy

My question wasn't how much power the supra would have after spending 10k dollars but how much you can get out of the standard turbos, standard intercooler and standard boost as someone told me there's had 400rwhp, i was looking at selling my scoob but am now gonna keep it, as john said he'd rather move around in something with similar power to weight ratio and something with alot better handling, i'm now upgrading my scooby with a bigger turbo and FMIC . I was just trying to confirm the validity of a statement made by a mate

LG John

Yeah, yeah, yeah............but 600bhp in the straights!!!!!! Ker-SHOVE

Don't assume Supras can't handle. If you look at the laptimes a couple of the heavily modded ones have made around the Nurburgring, it is clearly possible to make them handle extremely well. Admittedly, anything running say 400bhp/tonne is potentially going to be a bit of an animal in the wet, expecially if it's 2wd.

The Supra benefits from having 50% more capacity than a UK scoob, and stronger internals IIRC, not to mention better aerodynamics. Getting serious power and immense acceleration (the sort that very few scoobs can get near 60mph+) is not that difficult.

Having said that, I still don't feel the urge to buy one. If I ever get a genuinely quick coupe, I think it'll be a Noble.

Also depends on what transmission the supra has, if its automatic then on the quater mile it would be a load of crap, saw a 700bhp supra at Santa Pod, which looked the part with carbon fibre everything and rollcage, big exhaust, but kept getting 14seconds quarter mile. but if it had a rolling start on any road then it would take a seriously modded car to beat it(Skyline springs to mind). Just hope if your going to race him make sure its at the lights.

Muffleman

Nothing, guess what I'm doing next summer

And I've said it before in other threads, the first mod to a Supra should be Racelogic Traction Control.....period. Otherwise, it really is a bit of a handful I've only had mine for a couple of months, but I'm loving it. When the second turbo kicks in at 4000rpms, it's a real big grin moment
And with the Traction Control, I can even use it in the wet !!!

Matt

PS. http://www.t04r.com/ will whet your appetite, but just bear in mind that american HP is a bit different to our BHP !

Muffleman

Er, mines an auto and ran 13.08 with basic mods. Auto's are actually quite good on a Supra, so I don't know what was wrong with that 700bhp car.

Matt

wrxtasy

I agree with everyone who's posted on the thread, i've driven a mates supra n/a and it does handle well enough all though he has fish tailed it on a couple of sharp bend at high speeds, i also agree that the supra tt has much bigger modding capacity that a scooby, all i wanted to know is how much power a supra can get from standard turbo and standard intercooler etc . Also i leave my friends supra n/a for dead from the lights but the gap is smaller when we're both rolling, deffinitely a great car, just wanted to know the parametres of the engine,

thanks

Must be something wrong with it, I remember talking to him about it, and he bought it straight from japan the way it was, and I remember at the time i put it up on scoobynet about how much bhp it had and the times it got, and a few other people on Scoobynet who went to Santa pod saw it aswell, and said how crap his times was for what had been done to the engine. If you know of it, it was red, with carbonfibre bonnet, dark grey multispoke alloys and a few graphics on the side of the car. Not slagging supras of or anything, quite like them, but just thought automatic cars were no good from a standing start.

Andy.F

The worlds fastest scooby uses an automatic ! Saved over 1/2 a second from the 5 speed IIRC

Damn! Told you those automatics were good for quater mile.

Whats the time of the fastest quarter mile scooby. if anyone knows.

Muffleman

Sorry mate, got a little 'off topic'.

A JDM TT Supra is quoted at 280bhp, but is likely to be nearer 300bhp (it's that old 280bhp japanese gentlemens agreement again !)

I'm not an expert, but a full decat with performance exhaust and filter will see 340ish bhp, but you would have to have a boost gauge and a restrictor ring fitted to make sure the boost doesn't exceed 1.2bar, otherwise the standard turbo's wont last long.

Happy for an expert to tell me otherwise tho

All the best


Matt

Muffleman

Incidentally, a guy on mkivsupra.net has run a quarter mile of 11.962 with his JDM TT Auto, and on standard turbo's

ScoobyJawa

I've seen a lot of standard Jspecs get more, mine was 310!!!!

Adding a full zorst, decat, fcd, cooler plugs, restrictor ring to 1.2bar tops will give more like 380-400

Muffleman

Really ? Cool, I have an HKS ECU and FMIC aswell as the mods you mention (and more), I must therefore be over 400bhp !

TBH I was being cautious with the figures as I've not put mine on a RR. I would rather say it was 350bhp and get 400bhp on the rollers, than say it was 400bhp and get 350 !

Matt

wrxtasy

friend was offered a tt supra for 7000 pounds but was auto, i told him not to get it as it wouldn't be near as quick or exciting as the 6spd manual now i'm shoulda checked up first

Senior_AP

If it was a UK car - yes.

Jap imort - I would very much doubt it.

UK cars are miles better. Usually other way round but not in this case.

ScoobyJawa

Misinformed I'm afraid. Pluses and minuses for both, the only major difference being the turbos and brakes. The brakes are cheap to do, and was an option in Japan anyway, and the turbos can take a bit more power but take longer to spin up making the Jspec more responsive and a better daily driver. Big power means changing parts that would need changing on both anyway. I the real world there is bearly any difference, unless you want heated seats and *****'s on the front that the UK has. Oh - and the Uk is heavier too.

Covered to death on MKIVSUPRA.net.

Muffleman - I'd say you are defo knocking on 400 perhaps a bit more. Should be rather pokey

ScoobyJawa

The autos on a Supra are VERY good.

Stock figures give (depending on source) 4.5-5 secs to 60 for the man, and 5-5.5 for the auto.

Again though, real world driving in a drag the auto can be better as you just powerbrake and deck your right foot, no long gearchanges or missed changes, bad starts etc......

Senior_AP

A major flaw with Jap cars were the injectors. Import owners put UK injectors on them at a big price where most owners said "I should have just bought a UK car".

Plus UK cars have a bonnet vent.

ScoobyJawa

The injectors aren't really that much of a prob, and there are now direct replacements for the jspec that don't require resistor packs etc. They are fine to the limits of the turbo, though for big power you'd need to replace them on both.

LMAO @ the vent - I do know Jspec owners who've retro fitted it LOL!
