Need to know what rpm range I can expect to be getting full boost on diff types of turbos so I can decide which I want to buy.
Anyone with turbo's, can u post up at what rpm you obtain full boost pressure.

I found a Garrett GT40 A/R .58 Compressor 82 mm wheel, Turbine A/R .89... haven't heard of anyone running this one on the RA. I think it would lag as most turbines that people have are between .6-.7 on the RA - but the compressor is smaller than avg... what effect will this have..?
It's BB so it should spool a bit faster than norm too but I need input.

Please de-noob me, so I can begin my parts build-up

Evo's run gt40's and they're only 2.0l so a 2.4 should theoretically have enough flow for quick boost....?
This is one part of FI which flies right over my head...A/R's and wheel diameter stuff...is there a site which shows recommended turbo applications?

nvm

I have a Garrett GT2537 = 370hp I am running about12psi and max boost is at 4250rpm

^ impressive!

My JDM with stock turbo max boost is between 4200 and 4400 rpms

Well, I have the Mitsubishi BIG 16G (RRM kit) and it seems perfectly matched to our engines. Starts to boost around 3000rpms and hit's 7psi by 4000rpms. It's rated to 380hp.

flow: 550cfm
boost: 20+psi

I am runnin a t3/t4 and it start spooling around 2,800 and full boost soon after, turbo is good to over 400hp but i dont think i will ever get there with my RA nore would i want to with front wheel drive car hahaa

No way in hell you're going to efficiently run a GT40 on a Ralliart Not unless you intend to replace everything internally on the engine then crank the boost WAY up.

+1 on that.

Not on stock internals and low boost.

Ummm, are you serious? You want to put a GT40 on a Lancer?
