monsween Posted October 15, 2010 Share Posted October 15, 2010 Dont mean to be nasty but for what your thinking you really need to spend hours reading through build threads on here to see whats what. I've been here for 2 years and only now sort of understanding what i'd need to do for a reliable single. (reliable in the loosest terms lol) BPU plus suspension/brake setup would be what i'd advise you go for Quote Link to comment Share on other sites More sharing options...
Matt H Posted October 15, 2010 Share Posted October 15, 2010 Why do people say they want 500 bhp having never driven a car with this power ? In the 80s you would of won le mans with this power !! The guy hasn't driven a stock car , and wants more? It's a bit " I want 10 steaks " how about eat just the one first? Then lots on here advise him where to go to order 10 steaks LOL It's not the 80's and if man want 10 steaks, then if he has the money for the 10 steaks, then let him dine away.

Nic Posted October 15, 2010 Share Posted October 15, 2010 didnt realise it was 8-10k for single turbo. As a guide have a look in my garage HERE. The Garrett GT35R I was running is capable of making 550hp+, I've listed all the mods, practically all of these are essential to support the larger turbo and power. The price of the actual turbo kit is just a fraction of the final build cost, once you've factored in the fueling upgrades, electronics, cooling, etc. Quote Link to comment Share on other sites More sharing options...

jagman Posted October 15, 2010 Share Posted October 15, 2010 I had a 350bhp celica gt4 just got rid of it so a standard supra wud feel slow in comparison thats y am after 500 bhp lol You are moving from a 2ltr engine to a 3 ltr engine with about the same weight car , there is a large difference in torque !! you have been eating a bacon sandwich , first eat a steak then ask for more -see what I did there Quote Link to comment Share on other sites More sharing options...
Nic Posted October 15, 2010 Share Posted October 15, 2010 Just looked at your spec Nic, I'm thinking of some cam work myself. The cams would certainly help with your setup, if you are on the stock cams you will see the power start to drop off before the rev limit. Mine use to pull hard right to the 7K limit with the HKS cams. I'd probably go in264/ex264, the GT35R is so responsive that you'll probably not notice any loss in low down torque, but should feel it pulling harder mid to top end.

I think that's something I'll do over the winter. I like the idea of a bit more higher end without compromising the low end. That was always my vision for my set up.

That was always my vision for my set up. The cam upgrade makes a huge difference up top, you open up 6000-7000rpm rather than it choking up - you won't regret it although your rev limiter might I don't think anyone's noticed any low down power loss it's that minor.

Thanks, Ian. 264/264 then? If you were putting them in right now, who's would you use (HKS etc)? Quote Link to comment Share on other sites More sharing options...
Nic Posted October 15, 2010 Share Posted October 15, 2010 Thanks, Ian. 264/264 then? If you were putting them in right now, who's would you use (HKS etc)? I ran in256/ex264 on mine but that was because I'd fitted the cams a few years earlier when still BPU. CW built the head for me, he did some mild porting, recut the valve seats, replaced the seals and fitted the HKS cams. Low down response on mine was very quick and it would pull hard to the rev limit. I also had HKS cam gears on mine which the mapper spent time adjusting to get the best results. On yours I would go with HKS in264/ex264 cams and if you want adjustable cam gears I would recommend the JUN ones, you will need to get the mapping adjusting to suit.

Guest Master Seanis Posted October 15, 2010 Share Posted October 15, 2010 lol thanks for advice. I will go bpu and leave at that for a while. btw it runs rich at bpu doesnt it? does this cause problems at all? Quote Link to comment Share on other sites More sharing options...

It's setup slightly rich in stock form, at BPU levels fueling is fine but the stock fuel injectors are getting close to their limit. Quote Link to comment Share on other sites More sharing options...
Mistermann Posted October 16, 2010 Share Posted October 16, 2010 Why does a j-spec not need a boost controller? Fitting an uprated fuel pump isn't going to give you any more power, but it's a good idea to replace the tired 15+ year old OEM pump. What do you mean by controller? Boost controller? Not needed on a j-spec. And to "remap" the ECU you either need a standalone or piggy-back ECU as the stock ECU is not re-mappable like other manufacturers.

Nic Posted October 16, 2010 Share Posted October 16, 2010 (edited) Why does a j-spec not need a boost controller? Removing the cats on a J-spec will make the boost rise up to 1.4-1.5bar (as the wastegate on the J-spec turbos is small and is unable to flow enough to regulate the boost), this is the reason a restrictor ring is fitted in the exhaust to lower the boost to a safe level. So you don't 'need' a boost controller to raise the boost on a J-spec, but as my previous comments if it's a good one it can help maximise the power and minimise lag. http://mkivsupra.net/vbb/showpost.php?p=2925596&postcount=21 Edited October 16, 2010 by Nic (see edit history) Quote Link to comment Share on other sites More sharing options...
