jay_NW Posted December 1, 2006 Author Share Posted December 1, 2006 Hi Jay, nice project mate. Are you going to be lowering the compression by fitting TT pistons or what? Which ones (make) are you going for?[/quote the compression will be more than a n\a but not as much as the TT engine, the block is the same any way, and the engine is also being re-built.

Welcome to the club Jay and good luck with the install BTW: A turbo car should have LESS compression than an NA. Quote Link to comment Share on other sites More sharing options...

Less you mean. The NA's compression ratio is to high for forced induction really. Quote Link to comment Share on other sites More sharing options...
GazzaGSi Posted December 1, 2006 Share Posted December 1, 2006 approx how much Mine was roughly £3.2k inc VAT but supplied afew bits so it would of been more. That was not with the internals though. Setup for just over 400bhp sometimes 500 though Gaz Nice looking motor Jay, you wont look back. Had the conversion done months ago and going back in Jan for quite bit more Quote Link to comment Share on other sites More sharing options...

JamieP Posted December 1, 2006 Share Posted December 1, 2006 Ive read the NA box is good for 500bhp? Quote Link to comment Share on other sites More sharing options...
Tom Posted December 1, 2006 Share Posted December 1, 2006 Not a good idea to push the 5 speed box past 400bhp mate, maybe people get this confused with the R154 out of the mk3 which can take 500bhp+, n/a box is pushing it past 400 from what I've read/heard, however the 6 speed n/a can take as much as the TT box.

JamieP Posted December 1, 2006 Share Posted December 1, 2006 Had a look on supraforum and there seems to be mixed views... some say they run at over 500rwhp daily driver and have no issues, others have had problems at 350rwhp.... http://www.supraforums.com/forum/showthread.php?t=391880&highlight=w58 Quote Link to comment Share on other sites More sharing options...

I have seen few N/A's pushing just above 500bhp, even though am looking to upgrade the gearbox abt same time next year Quote Link to comment Share on other sites More sharing options...

tDR Posted December 1, 2006 Share Posted December 1, 2006 W58 5-Sp box in the N/A MKIV Supra is marginal at best. Driven hard it won't take much more than 300lb/ft torque through it. The tough 5-Sp is the R154 outta the Mk3 Supra Turbo (UK), 1JZ TT (Jap) or Soarer TT (Jap). That's good for over 500lb/ft torque aparently. Cheers, Brian.

mikeyb10supra Posted December 2, 2006 Share Posted December 2, 2006 what u guys think I will be pushing after the conversion, I am expectiong just abt 500BHP (which is slow compare to most your cars on here), but am just a beginer. are you joking you will have a very quick car there mate trust me and the power figure your quoting is a good output, imo anything over 600ish starts to become a real bitch to put down.....450-500rwhp is far more managable on the road and as tom said you want the r154 as the w85 is like playing russian roulette over 400, you will need the w85 bellhousing for the r154 if you decide to go down this route so bear that in mind Quote Link to comment Share on other sites More sharing options...
SupraStar 3000 Posted December 2, 2006 Share Posted December 2, 2006 Good luck jay. Its gona rock! Do Turbofit give a one year guarantee on all work? If so, you have no issues, especially if your planning on updrading the gearbox etc in the future. I'm saving for a Turbofit NA-T but to be honest, Christmas is not helping and next year I want to move house and find a new job (probably less pay) Quote Link to comment Share on other sites More sharing options...
