Turbo Selection Stagea VS Skyline

[Burns]

I have just been having a bit of a think about upgraded turbo selection for a RS4 Stagea and if the specs should be different to a turbo for a Skyline if the same results are desired. I had planed to get a 250kw GCG high flow job for My R33 and may one day want to do an upgrade on the Stagea.

Would the ideal turbo specs for a Stagea be the same as for the Skyline or would a turbo with different characteristics be more suitable when considering the Stageas extra weight and auto trans? I am guessing you would want it to develop peek boost at or just before the torque converter stall / lock up

Hey burns,

2530 would be a great upgrade. Bolts on, no probs, pulls hard.

Hmm, yeah you'd want something that came on quickly but you also need to factor in the higher drive train losses of the auto box and 4wd system so you can reach your goal power.

Bit new to all the parts name shortening/abbreviation... what is a "2530" turbo??

Oh and another dumb one while Im at it - what is an "AFM" lol??

2530 is a HKS-Garrett turbo, called a HKS2530.

AFM = Air Flow Meter

Hi Burns, I will be using a GCG ball bearing hi flow on our Stagea. With a split dump/engine pipe combo, hi flow cat, 3.25" exhaust and an adjustable exhaust camshaft pulley, I reckon I can tune it for ~0.5 bar at torque converter stall. That's using the Jaycar DFA for fuel tuning and the IEBC to keep the wastegate firmly closed. The power target is 200 4wkw at 1.1-1.2 bar.

PS; on the 4wd dyno the Stagea seems to loose around 15 rwkw more than a manual R33GTST does on the same dyno in 2wd. The Stagea was in second with the Snow and 4wd buttons on, as without them the ATTESSA kept moving the power from front to rear on the rollers.

Sounds like the GCG is still probably the best option.

Im getting 172kw at the rear wheels with a front mount, unshielded pod filter, SAFC turbo back Blitz Nur spec exhaust with a non split dump pipe on 12psi. I think I will get the brakes and handling sorted out to my liking before going for any more. Apart from fitting an air box or shield for the pod filter.
