I've just been surprised by someone who has a fairly stock UK Supra TT and reckons for about £5500 can get it to over 700rwhp with the following bits on a car that is currently stock apart from the exhaust:

1) Fuel kit (fuel rail, injectors, twin fuel pumps, fuel pressure regulators etc.)
2) FMIC
3) Exhaust already been done
4) Greddy emanage ecu piggyback
5) Oil catch tank
6) A bigger turbo

Turbo wise, he has quoted this:

If and only if you are looking for the best quality turbo kit to install on your Supra, stop here, you've found it. We at MVP have 6 years of experience working with virtually every turbo kit on the market and it is our firm conclusion that PHR consistently manufacturers the highest quality parts available to the public. Their turbos also tend to spool quicker and make more power than the others. We suspect this is because they custom build their own turbos using Garrett-manufactured parts (same as HKS) instead of the off-the-shelf Precision Turbos used by most of PHR's competitors. PHR kits are known for having extremely quick turbo spool yet producing as much power as more sluggish turbos like the T78 & T04R.

This is the exact same kit as the Stage 2, except for the turbo. This Stage 2+ (GT67) was originally tested by us here at MVP. On one of our Supras it turned just under 700rwhp on a bone stock motor. We added an intake manifold & achieved 728rwhp. But its not the power that makes this turbo special, its the power you get for the small amount of lag. This turbo hit full boost at 4,300 RPM's, only 100 RPM's after the Stage 2, yet was capable of another 40rwhp on a stock motor. This turbo, in our opinion, is the ultimate street turbo. We've driven almost every turbo available on the market from the T78 to the SP66 to the T51R, and this is the best turbo for the street. It is the perfect combination of power & *TRUE* daily driveability.

I will be stunned if that's all he needs to spend and do to get a car with that much power, seeing as the going rate to get a Skyline GTR up to that much power seems to be in the region of £30K.

Is that really right?

Dont believe the hype.

I just watched one Supra dyno with a 67 on it. It did just over 600 at 2.0 bar of boost.

You can do the same thing on a Skyline... just people trust what they hear in Japan too much, rather than what people do in the US.

 

[andreasgtr]

Yes, the question is what happens to the stock engine at 2 bar o boost.
I guess it won´t last that long.
To built a Skyline in that region (as you said 30k) costs so much because all the internals are strengthened etc. but I´m sure if you just do the most neccessary things you can hit big hp figures but the engine will give up MUCH earlier.

Safety and reliability costs money.

Another point to add is that you can run a lot more power on a Supra with a std bottom end. Those engines are SOLID!!!

[SkyJawa]

I believe the stock engine is good for 600bhp

 

[alex h]

I believe the max the yanks have got out of a stock engine is 921 or something like that...check www.t04r.com.
Whilst I'm not saying it's reliable or sensible - it's been done, it's fact.
If you don't add labour or delivery costs to the value of the goods available from the States that you need to run 700HP then it prolly would come in at £5.5k. However I think the person is not including incidental costs, mapping etc. A single kit for the Supra starts at £1800 in the UK from Vortex Power. That turbo kit is good for ~450-500RWHP. Depending on the turbo used. Fueling can be another £1800. FMIC £850+. etc etc...

Basically you can see it's not mega expensive but they have only looked at the parts prices.

Whats the most power anyone has gotten out of a stock bottom end in an RB in the UK ?

I did 654 rwhp and ran 10.7 @ 137 on a completely stock motor. Head,cams, manifolds, BOV, MAF, bottom end.

Mike F from DSport Magazine has done 763 awhp out of an all stock RB. Its possible, just have to step up and do it.

In the US the Supra stock bottom end could be had at a dealer for something ridiculous like $1800. So the guys would blow them up, get another stock bottom end for $1800 and start over. People kept pushing and pushing. Soon they were at crazy numbers.

980 rwhp though an automatic trans is the Supra "record". Although they have more "records" than anyone.

Recently one guy did 1453 rwhp out of his "street" car Supra, with a built motor

There are several built motor Supras up over the 1000 rwhp mark.

 

[MichaelG]

1453 rwhp !!

out of interest what would that thing do in the 1/4 mile ?

Michael

 

[tyndago]

1453 is Saad Saads Supra. It has run in the high 9's around 150~158 mph, not using the full potential.... its a 6 speed so driving its pretty hard. There are excuses and threads for days on www.supraforums.com. Spins in 3rd on slicks, anti lag, etc, etc, etc.

Another guy with a "street" Supra. Though an automatic. 1248 rwhp just went [email protected] Sound Performance in Chicago. A few of my old friends work up at Sound Performance

 

[kingsley]

Thanks for the posts guys.

Is it therefore fair to assume that doing a proper job on a Supra has a similar £/bhp than doing it to an RB26? *

* assuming that the power you're aiming for isn't in the range above which the stock RB bottom end is strained and below which the stock Supra bottom end is (thus meaning you'd have to change the bottom end on the Skyline but not Supra).

 

[MichaelG]

Sean - Why is it every time i read your posts i always want to emigrate to USA just to be in the thick of fast Imports lol

 

[Yunis A]

well if top tuners are charging very high labour charges it no wonder it costs 30k to get a high spec skyline... parts themselves should not be more than about 10k

Depends what parts you want to use i suppose, all probably down to personal preference, bearing in mind the price of a decent single turbo setup, inlet, plenum, head work, fuel system.

I have seen what Keith has spent on his Drag Car, and am just quite happy to sit back and support him and watch while he spends the money. All credit though, maximum effort for a car thats sure to be a monster in 2005. :smokin:

I specialise in Supra twin turbos and have heard all the bullshit and some more. The Supra world is currently full of cheap single turbo kits and impecunious owners who think 6K will give them a reliable 700 BHP. My honest estimate is this. Send me a stock Supra TT, expect the whole car to give and live with a reliable 700 BHP, and you will need to spend well over 25 K to achieve this. The USA market is heavily into drag racing. I can build a Supra TT engine that gives mega power for a 1/4 of a mile, but on the way home from the drag strip, when you are "racing" your mates down the motorway, i can almost guarantee an engine failure, or other drivetrain whoopsie. Currently there is a cringingly embarrasingly amount of BS talked about Supra TT's, probably because 5k will buy you a ropey but usable TT and that puts them in idiot territory. Harsh? Probably... Fact? Damned right! Another superb Jap "supercar" enters its finale.

micheal g

the last place you want to go to is the usa
you don;t shout loud enough
get yourself to china
crap cars,lovely food
bye now

 

[MichaelG]

Yeah but they aint got blonde honies with legs to the skyyyyyyy in China

OR much feckin Snow !!!!

I still reckon the Calder Supra was by far one of, if not the best 2wd drag car i have seen running in the UK yet, theres something about supras that is timeless.....they still look aggressive when kitted and "singled up" heh heh :smokin:

Chris,

Interesting post. How much of that 25K+ would be the cost of the parts and how much would be labour?

 

[AJFleming]

Why dont you ask Dan0h about people tuning stock Supra motors to that kind of power ;-) I am sure he could tell you some blood curdling stories about some guys from the US.....

Grr just wrote a nice long thingy but didnt get posted ,, maybe god didnt want others to read it

Ok Are Supras cheaper to tune than Skylines ???
the answer is YES.

buying parts from Japan is almost the same for both cars a good example would be piston prices of 1350USD for both the cars. However, the Supra has been in the US for quite some time now, it gave opertunaties for US companies to make their own parts such as pistons, rods, crank, cams, turbos, and injectors. dropping the price more than half, 550USD for a set of pistons for the Supra.

Saying all the above, some people will say bolt on a turbo upgrade the fuel system and you get 600+hp for the supra,, the same priciple applies for the Skyline. but they will never last. they never do.
