Tell a Supra owner about the smaller HKS twin setups

[Suprascene]

I currently own a 1995 BLK/BLK 6speed MKIV Supra. I did some research on the smaller HKS twin setups for my car i.e. 2530, 2530R, 2535, 2535R, 2540, 2540R, etc etc. Anyhow, just wanted to know your response to how you like them, the turbo characteristics and so on. The turbo lag is my biggest problem with the 2835 kit on a MKIV. So instead of a smaller a/r which would defeat the purpose of the kit, and with no need for such top end I'm looking to go smaller. Thanks All!

The 2510s would have the best low end response of all the HKS GT series turbos. It's the smallest in the series and can spit out anything between 400-480 hp if tuned properly and married to the right cams. I have raced with a 2510 equipped GTR R32 and off the line it was really fast but after 5500 rpm it could not hold up against my 2540s. My 2540s are a bit laggy (power would sneak in at 3500 and peak at 6000) but the top end after 6000 rpm would cause a whiplash!! My car is ported and polished according to Top Secret stage 2 menu to overcome the lag while the cames are 264 in and 272 ex. The top end in my opinion more than balance out the low end defficiency. The 2530 is probably the best bet for both world. A bit smaller to the 2540, it gives good low end and top end ( good for 550 hp - 600 hp). The Supra IMHO would do well with either 2530 or 2540 as it is a 3 litre car - the low end is ample. Use either 264-264 or 264-272 cames, it will be excellent.

Thanks for that info.. the only twin setup that will work with the hks starter kit are the 2540R's. It will need some custom work but will flow with the best of them. Won't be near those 800 monsters that we have but sure will smoke em. On an MKIV I have been told that basicaly it can stay with a 2835 or 2835R car and beat them until top top top end over 160+ mph.. so since I myself nor any of my friends have ever gotten up there I'm sure this will be the next big thing for the mkiv or atleast who ever has it will have the ultimate street/quarter mkiv. With spool similar to singles and top end like some of the best of em this setup should be the best all round for the mkiv.. or atleast, let's hope so.

the setup with a minorly tuned mkiv I was told would be around 640-680. With a built motor, the right tuning, the right stuff, and some luck I would easily say over 700 in an mkiv that spools quicker then the monster dyno queen twin setups driving around. plus the fact that it might be able to handle the power to the wheels a little better compared to the other twin setups..

I can't decide to wait for someone else to do this setup or if I should make the step myself after all the research..

Properly tuned, the 2540 can give excellent top end power. My GTR clocked 302 kph (188 mph) at 8200rpm in 5th (red line is at 8500rpm) after they were fitted. The Supra should be able to achieve that without problem.
Go and get it done mate....

See I knew it was good to post this question here, you guys have experience with the setup on a somewhat of a similar basis. I just wonder why no one has done it yet.. HKS makes the starter kit for a reason yet, no one has taken advantage of it.. I just might, I mean I really couldn't go single.. I love the idea of twins and I know deep down it should be the way to go.. I mean it just seems right.. 188mph is more then enough top end then anyone needs, I just can't believe people go with the 2835 or even worse the 2835R kits when they are as laggy as they are.. I'm going to have to find the funds for such a project being that I'm sure I'll have to do everything right and say goodbye to my mkiv for 4 months or so at least without taking into mind delivery time of the hks starter kit and or the 2540R turbos. So far I have only located 1 in the states at horsepowerfreaks, the other would take some time to ship in.. I dunno where to begin but I will surely look into it. R33 you've honestly helped me a lot and helped me with deciding the future of my mkiv

Without intending to confuae you in any way, I have to tell you that I have read of a Supra over here with a single HKS TO4R pumping about 550 hp using Link's electronic. My friend put that in his GTR and is pumping about 530 rwhp at about 1.3 bar of boost. The lag is not much and on the track it compares to mine. TO4R is rarely used but from what I heard is popular in Japan among drag racers. You may want to check it out too before any decision is made. Well, good luck in your project.

Oh we use them hear and hybrids of it.. we have some shops that have some customs turbos that out do the hks, greddy/trust, and the best of em.. Thanks for the kind words and the adive/info I'll keep you and everyone updated on my progress..

Hey Suprascene, just heard from rumoursville that HKS had just released (or probably is about to release) a GT series turbo which is right in the middle of 2530 and 2540 called...what else...the GT2535. This one will probably give the best of both worlds.

[Gtr2.7L]

As far as I've seen, the GT2535 is for use on the SR20DET's in the Sylvias.....Or maybe you're starting to see a kit designed specifically for the GTR's???

[R33]

Not too sure about that though. But, can't you use 2 of these on a GTR? Will try and get some more info.

[Suprascene]

Keep us posted on your findings. But we have that turbo in the US already. If not I'm sure Garrett makes a similar turbo (dif housing of course) but about the same since Garrett GT Turbines = HKS GT Turbines kinda.. lol well keep us updated and thanks again!
