I know the twin turbo 3ltr sequential twin turbo supra has a lot of potential. But I was just wondering if anyone knows what rwkw are achievable with the following mods

- After market cooler

- Power FC or equivalent

- full exhaust system from turbos back.

- boost increase with stock turbos

From reading these forums and from personal experience these mods on a RB25 with 10-12psi of boost ~200rwkw seems to achievable. I know the supra will make a lot more power than this but how much more?

The most you will probably get with the mods on a Jap spec supra would be around 250-260 rwkw...

The US spec supra's would be able to hit the 300 mark as the turbos are different as well as haveing bigger injectors and a more aggressive intake cam...

upping the boost on the stock setup doesn't always work as well as you would think as the sequential system is controlled by the computer but there are some tricks you can do... :)

Parts are a little more expensive but because the supra was built in the US also, you have a bigger choice...

The only probalem I have had so far is Traction... It is a very fun car but fi you want the full potential you need some good quality wide rubber on the rears...

The reason for the RB26 to go into some of the Jap Supra's is because the RB26 doesn't make as much torque as the 2J...

Also I think the UK run that he did was an RB26 powered Supra.. something like that..

Thinks looked grim. Even with an interpreter, Mr Nagata's on line of defence was: "Come on, you honour, 130mph isn't that fast." The police had also seized the video evidence of his earlier shenanigans, which probably featured a close-up of the Stack system showing 310kph - a piffling 194mph.

Amazingly, the fine was £155, plus £35 costs, plus a 28 day ban from driving on English roads.

With that, it was over. British justice at its cryptic best. In local and national news, police would be quoted as being "astonished" at the punishment, calling this "the sort of maniac driving at daft speeds that the courts should be cracking down on."

We left Court One and congregated outside. Normally reserved, Mr Nagata beamed and once more gave a thumbs-up. He said something to Taka, who immediately translated... "Mr Nagata said that when he comes back to England next summer, he will definitely crack the 200mph-barrier."

What a champ.

Most would say supra would win -- but this is a skyline forum -- you're standing on other peoples "ego".

but personally...i'd sell my line and go for the RZ supra anyday.

the amount of HP it can achieve with stock internals are way better than skylines.

Well.. when we were at the dyno day with OCAU a supra running pretty much the same setup except it was running a SAFC2 and a boost controller I believe.. he reeled off about 240kw..

it was 212rwkw on the first run and the later runs were lower as it started experiencing heatsoak

Just took your advice thanks mate found this thread

My brother definetely has a problem with traction! He's got 18x9.5's on the rear with Toyo TPG's and spins the rears just trying to change gears! He's also got an Exedy triple plate clutch which is an absolute pain for the street (previous owner installed it for drags) which also makes for interesting driving!

"Mmmm, unexplained bacon."

2JZ-GTE into an R33 is stupidity in my opinion.  2JZ with the 6 speed costs an absolute fortune, and an RB26 can make similar power.  If you really want the BIG CUBE straight six, you could probably build a killer RB30DETT for less than a 2JZ engine swap.  The cost of installing a 2JZ would be phenomenal.

I hope you're referring to the RB30 engine ie from R31 days. Because i know stroker kits for the RB26 engines are amazingly expensive.... (think $28000+)

2JZ's are better engines then the RB26, but probably not good enough to warrant an entire engine swap. Better off going for the 1JZ, which are around half the cost, and of similiar potential. 1JZs are a LOT better then the RB25s

I know the hard tuned supras will kill the r33 gtst but im talking about both cars having the mods listed in the first post. So we have

Skyline 200rwkw

Supra 240-250rwkw

Skyline has a 200kg advantage but 50rwkw is a lot to make up for. But I have been over to the supra forums for a look cars with these mods are running low 13s to high 12s very similiar to the 33 GTST Skylines.

cheers

i love the fact that everyone that says "id swap my line for a supra" all have a r33 gtst!

i say take a modded gtr and then a modded supra for a drive, then make up your minds.......

steve

True. But he is comparing the RB25 to the 2JZ, thus the reason there are probably lots of R33 Gts-t'ers in here including myself.

Tell me though, how does the comfort and interior of an RZ Supra compare to the R32?

who on earth compares the rb25 with the 2jz?

go the rb26 and then it'll be a fair comparison, tho its not to say that there arent GTST/GTT's out there which will spank supra rz's and vice versa

i'll admit that i had always liked supra's .. wanted to get one since i started saving up for a car.. but in the end, i went a GTT over the supra rz due to many reasons including age vs price, capacity vs fuel consumption

The interior of a Supra isn't built for anymore than 2 people really, unless the people in the back are short or have no legs. There's more room than in the back of an S13 Silvia, but the rear window is sloped so any passangers better not be tall or have no necks. The glove box on the passenger side kind of juts out, so if someone is in the back the person in the front passenger seat will be squashed and at worst have their knees under their chin!

But who really buys a car like this to transport 3 or more people on a regular basis? With out passengers there's ample leg room. The 'fighter pilot cockpit' look may or may not be to everyone's taste, the way the aircon and stereo controls 'wrap around you' but I reckon it's good.

I personally like the climate control system in Skylines better though, the way all the controls are contained within a single unit and there are no dials/knobs to speak of for fan speed, temperature etc. as there are in the Supra. My brother's car came with Recaro's as a factory option so comfort here is triple plus.

"Mmmm, unexplained bacon."

I’m only comparing the two with the mods listed in the first post I already knew it would make more power and beyond these levels the Supra has far more potential than the r33 GTST.

But after that level of modification things start to get expensive upgraded turbos fuel systems ect. After searching the supra forums for cars with similar mods the r33 listed in the first post the gtst and supra run similar times down the quarter at this level.

Does anyone else have some dyno charts or times for the supra with the the mods listed in the first post? and perhaps some GTR dyno runs and times with similar mods ill say it once more listed in the first post?

Cheers people just thought it might be an interesting thread.

my house mate has a Stock RZ TT Supra. I have an R33 gtst with basic mods (FMIC, Pod, 3" turbo back, boost around 11psi). ive driven his, and honestly they can be compared to in that sence. i also have a chaser with a 1jz. we both got our toyotas on the same day, both with no mods, and the chaser keeps up til around 3rd gear, and then the twins in the RZ spool away.

but i agree that you cant compare toyotas best sports car to the gtst, it should be against nissans king, the gtr.

the gtst and the Rz are two different cars. one is a [japanese] family coupe, the other is pure sports.

Thanks everyone I know that the supra is quicker over the 1/4 than the r33 gtst from the factory.

How would a R33 GTS-T fare against a the supra both in street trim at this level of modification assuming they both have a decent suspention/tyre setup. Keeping in mind the supra weighs 200kg's more.

I know that the skyline is capable of high 12's what can the supra do?

Supra is capable of high 10's (10.7 -10.8) with stock engine, subzero ran a high nine with stock engine aparently.

    • GTSBoy on your suggestion on another thread I had a look at those injectors and ended up getting them because of the quality.  Got the expensive ones.  
    • Hey guys been looking everywhere to try and find the correct gtr hood latch support part number but only found the first half and when I search with that number it sends me to an r34. The first part I found was 62515. If anyone could help me with the rest then I’d really appreciate it. Or if there’s some alternative hood latch support that would work even better cause I can’t find any for sale. (Searched on upgarage, partsouq,buyee,rhdjapan) 
    • If you've only done the upper control arms on the rear, AND you have changed their length (by more than about 1mm) to set the camber you want, then you will definitely need/want to install traction arms also. Adjusting the camber arms on their own WILL introduce bump steer and make the car unpleasant to drive. Most owners have no idea that their car could behave infinitely better than what they put up with. I'm not entirely sure what the Stageas need, but I am thinking that unless you have massive front spring rates and pretty soft rear springs, you have waaaay too much rear bar. Oversteer city, in my estimation. Combined with possible excessive bump steer from maladjusted arms, that could be a recipe for nastiness. ATR43SS2 is not a highflow. It is an outright replacement turbo. It's a little bit bigger than the largest highflow profile that Tao does. Probably a solid 300rwkW turbo where the bigger highflows will be about 30-40rwkW less. Nevertheless, we're only talking about ~300 rwkW, which is well within the abilities of the stock ECu to run with a Nistune on board. I would do so without hesitation - and I will be doing so when I get my finger out and actually get the injectors and AFM installed. But, if you would prefer to drop a whole lot more money on the ECU side, then I suspect you're looking at Haltech. The Haltech fanbois here will all spout on about all the available engine protection you can have, that you can't have with the Nistune option. And they're right. But it doesn't really come for free either. You will spend more money on extra sensors and the like, plus the work to install them. If the engine was built and therefore represented a big investment to protect, then I'd say definitely do it. If you view the current (and forever into the future) shortage of replacement engines as something to prompt similar protection, then also, do it. If you see a destroyed RB25 as an opportunity to put in a Mercedes or other V12 (like I kinda do)... then your perception of the risk/reward might differ. These are good injectors. You can also get a "better" set of the same with more flow matching, for more $$. 1000cc is where you will want to be. You will need an R35 AFM and adapter tube if you want to stay with Nistuned stock ECU. Otherwise, if going Haltech, you can ignore. As for intercooler. Just about anything will do. You're only talking about ~300rwkW. Just put a big core in there. Be aware that return flows do add significant pressure drop and will cost power and will make the turbo work harder to achieve the same goals. If you can manage a proper crossflow, do it. I'm keeping my very good return flow because I'm only expecting to be in the ~250rwkW range, and will live with whatever outcome I get.
    • I have a heap that i have collected if you want some authentic ones still. Pm me if your interested!
