ok so I am ready to purchase the turbo... yay... I want the GT30R, figured GT35R would be a touch laggy for me. But I want to know what you guys think about housings, HERE is where I plan on buying the turbo, EBay seems to have nice deals on them.

I will be getting the T3 flange with 4 bolt exit, and the compressor has the .60 A/R, I think I should go with a .63 A/R for the turbine (exhaust) side, because I remember somewhere it is a good thing to match the A/R's for the compressor and the exhaust to be pretty near the same for maximum efficiency, also, I think the .84 may spool a bit slower for a 4-cylender, being more free flowing (that is how it work right?) and not offer many gains, I dunno will a LD9 with a .040 overbore produce enough exhaust (with around 20psi) to constitute a larger exhaust housing? This is my thinking, what you guys think is best, not looking for more than 400hp here.

*yet at least





22 miles per gallon and dropping fast...

Don't buy that turbo from anybody but Majestic Turbo in Waco,TX.

There are one of the best turbo guys around.

Get it from a company that will not give you problems incase you need to have warranty work done.

I got my GT3067r from cheapturbo.com.... works like a charm.
