Jim.c Posted September 14, 2016 Share Posted September 14, 2016 Hi I am tuning a NA starlet for sprint racing it is just lacking a bit of power at the top end of the Rev range. I have a corolla inlet manifold and Corolla 4-2-1 exhaust manifold blitz panel filter and lightweight flywheel with glanza clutch and advice appreciated cheers Quote Link to post Share on other sites
richardc9052 Posted September 14, 2016 Share Posted September 14, 2016 2" straight pipe. Depending on noise restrictions Quote Link to post Share on other sites
Jim.c Posted September 14, 2016 Author Share Posted September 14, 2016 It can be up to 102db but don't want it no where near that loud my gt4 is 101 and it is far too loud. Would removing the cat and centre box out of the standard pipe be any good Quote Link to post Share on other sites
richardc9052 Posted September 14, 2016 Share Posted September 14, 2016 It's n.a.. if your not prepared to make sacrifices you won't get every last drop out of it and believe me, your squeezing a dry lemon. Quote Link to post Share on other sites
Jim.c Posted September 14, 2016 Author Share Posted September 14, 2016 Yeah it's easy on a turbo just turn the boost up job done lol. Yea don't mind it being noisy but just not silly load my gt4 only just passes the noise test a croft and on the road it is just too load was hoping to keep this bearable Quote Link to post Share on other sites
jimmymac101 Posted September 14, 2016 Share Posted September 14, 2016 could always stick in a 5efe to gain abit more! there's a guide on the forum about how to get the most out of 4efe .... il see if i can find it James Quote Link to post Share on other sites
jimmymac101 Posted September 14, 2016 Share Posted September 14, 2016 no luck but i remember it as it was started by ryan lang who put loads of effort into his 4efe Quote Link to post Share on other sites
Jim.c Posted September 14, 2016 Author Share Posted September 14, 2016 Thanks that would be great. Need to keep it 1.3 for now or I will not be able to enter in the class I want to be in thanks James Quote Link to post Share on other sites
Jim.c Posted September 14, 2016 Author Share Posted September 14, 2016 Ok cheers anyway will have to try find it tonight Quote Link to post Share on other sites
richardc9052 Posted September 14, 2016 Share Posted September 14, 2016 The best setup I found for mine before I want turbo was:Jdm 100ps 4efe 20v 4age mani modified to 4efe flangeFull straight 2" with backboxFull 4efte engine loom, inlet mani, tb and sensors4efte clutch and flywheelI would recommend either c56 lad Levin box or c160 lsd if your on track and a lightened flywheel. That way it's still all "standard" parts apart from exhaust and flywheel Quote Link to post Share on other sites
