I'm having a tough time choosing between the two. Assume same price and same condition.

This is for my 93 Civic EX (d16z6). My plans are for a good daily driver and the monthly autox. Both will be run on an HF manifold.

The Greddy is a TD40H-15G and the WRX is a TD04L-13T

 

My WRX turbo has no problems holding 13psi till redline and it makes 13psi around 3700rpms...

Greddy turbo also is only oil coolered the wrx is both.

The Greddy turbo should come with a O2 housing that will clear your frame stuff, the WRX turbo will require that you have the WRX's factory DP to make a custom DP out of..

 

yeah, a wrx turbo will start to poop out at around 16 lbs of boost, but is well capable of making it on a wrx.

 

you don't need the factory dp from the wrx...you can order a flange from www.uniquemotorsports.com and get some mandrel bends from www.jcwhitney.com and make your dp. much better that way. you'll also want to order the turbine inlet flange too so it'll be easier making your adapter plate...it's an ihi 3 bolt flange.

 

I wish I'd have seen that page... I paid $65 shipped for a stock WRX DP and had a friend weld to the exsisting pipe, but it does make a 90* bend right off the turbo = no good.
