Newbie here, I'm getting ready to send my engine in for a rebuild (scored#4). I want to go turbo (Greddy Turbo Kit) after the engine break in period ~500-1000miles. My main question is which ratio to rebuild the shortblock for: 11:1 (factory), 9.5:1, or 9.0:1 (from S2KI forums)?... thanks

 

u should do a 10:1 or maybe a 9:1 doubt with the greddy u will need a 9:1

 

The Greddy is a fairly mild setup and is designed for stock compression. I'm not sure if it can be produce enough boost efficiently to warrant lower compression.

If I was in your situation I would go for the Inline Kit instead.

 

I would go with 9:1 regardless of the turbo kit. Even with the greddy kit and 9:1 you will be faster than stock. Then if you ever want more power you wont have to rebuild it.

 

I think low compression and the Inline (or similar) kit is a great combo.

I think the Greddy and stock compression is a great set up.

I think Greddy and low compression is not a good idea.

 

^ I agree

 

Guys, thanks for the suggestions... I have a budget of ~4000 for a turbo kit, ~4000 for the shortblock rebuild, and ~1000 for tuning.

Will a 9:1 ratio shortblock with a Greddy kit get me close to the 280-300whp? if not then how much $$ am I looking to spend to get 280-300whp from a turbo kit (Inline, Lovefab, etc...). Not looking for a Monster whp. Or will a 10:1 ratio shortblock as Dsgs2k3 suggested with Greddy kit get me close to 280-300whp?

Thanks in advance for all comments and/or suggestions

 

with a 10:1 you could go all out with the greddy kit and make well over 300

 

if you just want the greddy kit just get a replacement short block, no need to build an engine

 

The price difference is ~1500 for a sleeved rebuild (ratio?) -v- factory shortblock. The question is which one will suit best for mild boost to reach a goal of 280-300whp for DD? If it is a factory replacement then what year to order for '00 chassis?... thanks
