What Is Needed..?

[Kane_GSR]

Ok I'm trying to work out how to achieve a quick street car without spending a shit load :lol:

I need to know what is needed to see around 200awkw from the beloved 4G63T..

I'm imagining a full rebuild with forgies, cams, bigger turbo..

What are the limits of the stock bottom end, with the right turbo/ecu/cams is it possible to achieve 200awkw with reliability (I know the tune/tuner is taken into account) without needing to have a full rebuild prior?

depends obviously its for your VR4? 200 in a fwd aint so bad but when your trying to get it at all 4 i think it would take abit more...
i only have ARP head studs GT30/71R Microtech 3" zorst....but i'll be up for a rebuild soon enough...just hope it doesnt go bang just yet...

All you need for 200kW @ wheels is:

Some compression, 140psi or more and pretty even over all 4 cyls (even a high km motor should provide that unless it's poked.

A 16G turbo (it's do-able with a 14b, but there's more power availible from a 16G with basically no downside).

510cc injectors

Evo/magna maf

Chipped ecu (with datalogger please)

walbro pump

intercooler and piping (j-spec with 2.5" pipes will do fine)

and some sort of boost controller set to 20psi or so.

use the datalogger to make sure there's no knock, and a stock high kay motor will handle this indefinitely - no real need to rebuild unless you have no compression (piston ring land damage) even then new rings and bearings and a quick hone will do.

pump/ecu chip/maf is all that I'm missing, do you have proof though :w00t:

there are guys in NZ running 11-12 second 1/4 mile with stock bottom end.

tim (brisvr4) is running 12s with a stock bottom end and with arp head studs a head gasket and some cams and springs
