When Does Full Boost Come On For A Gt-rs Turbo?

[zafeniak]

Hi guys,

I've done some research and I want to buy a GT-RS turbo.

However, I was concerened about the lag issue.

Could the people who have a GT-RS turbo tell me when they hit full boost (at what RPM) and what boost they are running?

I am aiming to get around 240RWKW from my car.

Current mods include:

Full 3.5" straight through exhaust

GReddy Front mount intercooler

Splitfire coil packs

Power FC

Bosch 040 Fuel pump

Cold air intake system with pod and heat shield

Boost controller set to 12 PSI.

Currently, my car is putting out 195 RWKW with the current mods. Should I be able to reach 240 RWKW with the GT-RS with bigger injectors (550 CC)?

I've also read about the HKS 2530 but I read that it only could pull out about 220 RWKW. Is there a turbo that is in between the GT-RS and the HKS 2530 and that isn't so laggy?

Cheers!

Have i missed something, but what sort of engine?

A 350 chev with gtrs will start spooling at around 1000 rpm
