More top end power

[Jim.c]

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

2" straight pipe. Depending on noise restrictions

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

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.

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

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

no luck but i remember it as it was started by ryan lang who put loads of effort into his 4efe

[Jim.c]

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

[Jim.c]

Ok cheers anyway will have to try find it tonight

The best setup I found for mine before I want turbo was:

Jdm 100ps 4efe

20v 4age mani modified to 4efe flange

Full straight 2" with backbox

Full 4efte engine loom, inlet mani, tb and sensors

4efte clutch and flywheel

I 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
