GT4088R?

[Remps]

I was looking at the garrett site today,and at a 2.7 pressure ratio,60 lbs a minute for 425 rwhp(is what I calculated)the GT4088R with a .85 ar turbine housing looked just right on the compressor map.Will the T4 inlet flange work or would it have to be adapted somehow?I know they are expensive,I just want one.

You need a T3 flange.

they make T3-T4 adaptors all day long for about $29 - $69 on Ebay

Gonna be real laggy on the street though wont it.?

I think it'll be tolerable.I don't drive around town much anyway,mostly highway.I figured it would be a good high speed/low temp turbo also.One size smaller at 425 rwhp is almost off the compressor map.I plan on buying a 4X4 and this will be my hot rod eneways.

Just making sure he knew that he couldn't just bolt a T4 up to his truck.

You'll also need an oil restrictor and need to plumb in water lines, the ball bearing garretts are water cooled. I'm pretty sure with a 77 mm turbine wheel its going to take you a long time to spool it. the 3788r is sold as an upgrade for 2nd and 3rd gens and has the t3, and everything you need. It's a 63.5/72.5

The ball bearing turbos have a built in oil restrictor.The compressor map on that 3788R looks even better then the 4088R.Wider range bottom and top.So any turbo with a T3 flange will bolt to the stock exhaust manifold?(Although if I spent the money on this turbo,I'd get a manifold too)

I'm sure you could find it cheaper but this is the one i was talking about.

Yep, a T3 flange will bolt up.
