SupraPL Posted April 16, 2007 Share Posted April 16, 2007 Who is interested in group buy? http://www.mkivsupra.net/vbb/showthread.php?p=1369590#post1369590 Hello guys. I'm looking for N/A-T kit for my JDM non turbo, 5 speed manual Supra. My goal is 400 - 420 BHP @ flywheel (up to 1.2 bar). I don't need big turbo for 600BHP I use the car as my second car (just my toy), but it must be still very reliable after modification. That's my highest priority: 1. reliability 2. power up to 420 BHP. I'm very curious what your choices might be. Regards Tomasz PS I prefer spend more £ for a top quality kit, rather than pay less for something crap ... Quote Link to comment Share on other sites More sharing options...

turbonut Posted April 16, 2007 Share Posted April 16, 2007 Of course, but it is US forum the advice is the same, as they bolt on to the same cars no matter what side of the pond you are on. I've been looking into these for a while now and Boost Logic would seem a good choice. Quote Link to comment Share on other sites More sharing options...
steve spedd Posted April 16, 2007 Share Posted April 16, 2007 Almost forgot: where is in your opinion the best place to fit turbo kit?

Nic Posted April 16, 2007 Share Posted April 16, 2007 In terms of quality, I would personally go with either the Boost Logic or Powerhouse Racing kits. Quote Link to comment Share on other sites More sharing options...
Sheefa Posted April 16, 2007 Share Posted April 16, 2007 I'd personally give Greg a shout at Turbofit mate. He's done plenty of NA-Ts and Single Installs and they certainly do their installs well! They had a 550 NA-T up on the rollers recently! Turbofit.co.uk and go to contact us and drop them a line. I think they did Voo51 (Vicki's) single convo too not long ago and that's a beast!

PHR kit is my favourite for the moment. I will do research about boostlogic kit on my next days off. Quote Link to comment Share on other sites More sharing options...
Matt _Aero top_ Posted April 16, 2007 Share Posted April 16, 2007 Theres a few of us out there thats planning the NA-T conversion sometime this year , myself included ( hopefully ) Just got abit more tarting up to do on the sup so its a perfect base car for the conversion but my main concern will be reliability also as the sups my everyday drive .

SupraPL Posted April 16, 2007 Author Share Posted April 16, 2007 Boost Logic Stage I NA-Turbo Kit "This kit contains everything you need to convert your Non Turbo MKIV Supra or SC300 into a turbo charged sleeper. The Stage I Kit enables you to make upwards of 300RWHP at 7psi." PHR Stage 1 Single Turbo System " The Stage 1 Single Turbo System for the Non Turbo Supra offers approximately 310-320 RWHP for automatic owners, and 320-330 RWHP for five speed manual cars at 8 psi of boost pressure." I have got three questions: 1. 7-8 PSI = ? bar 2. 330RWHP = ??? BHP at flywheel 3. Which turbo is better for 400-420BHP? Which one will start spool faster? Garrett GT60 turbocharger (PHR) or T61 .58A/R Ptrim Turbo w/ T4 flange (Boostlogic) Cheers Tomasz Quote Link to comment Share on other sites More sharing options...
Matt _Aero top_ Posted April 16, 2007 Share Posted April 16, 2007 I think 7 psi is 0.5 bar so its low pressure Quote Link to comment Share on other sites More sharing options...

Which one will start spool faster? Garrett GT60 turbocharger (PHR) or T61 .58A/R Ptrim Turbo w/ T4 flange (Boostlogic) Cheers Tomasz Hi Tomasz You are limited in the boost you can run due to the higher compression ratio of the 2JZGTE engine and also the fuel system. To do the job 'properly' you would need to fit new pistons to lower the compression and fit all new fuel system. I would personally not consider fitting a turbo on an NA, if it was me I would either sell the car and buy a TT (the best and cheapest option IMO) or fit a TT engine in the car. Fitting a turbo kit on an NA and making it 'reliably' run 400+ hp will cost a LOT more than either of the above options. cheers Quote Link to comment Share on other sites More sharing options...

RobSheffield Posted April 16, 2007 Share Posted April 16, 2007 Im not sure most NA-Ts run as high a boost pressure as 1.2 Quote Link to comment Share on other sites More sharing options...
Nic Posted April 16, 2007 Share Posted April 16, 2007 My polish mate's Supra got 420 BHP at 1.2 bar. NA or TT? To run that boost on an NA you would need to reduce the compression ratio. Quote Link to comment Share on other sites More sharing options...

To do the job 'properly' you would need to fit new pistons to lower the compression and fit all new fuel system. My mate's Supra use OEM TT headgasket to lower the compression. Two years passed since conversion was done and hadn't any problems at all. I would personally not consider fitting a turbo on an NA, if it was me I would either sell the car and buy a TT (the best and cheapest option IMO) or fit a TT engine in the car. No way! I bought my 2002 SZ because i want own car as young as possible. I will never sell it! Fitting a turbo kit on an NA and making it 'reliably' run 400+ hp will cost a LOT more than either of the above options. cheers Yes i know Thank you very much Nick.
