How much BOOST on a LQ9??
 

I've been thinking about putting my built LQ9 from my 95' in the 04' truck just wondering how much boost it could take?? I'm looking for something that's a BLAST to drive and could be used as a DD. I'd like to see 600rwhp maybe a touch more:D That's kinda the goal I'm looking at. Just looking for suggestions and ideas before I start making any purchases.

I already know it would need a different cam,heads and head gaskets. The heads have been milled so I figured since I already had the high compression pistons it would be best to change them out.

I had planned on a low mileage LQ4 but I put so much in this engine I figured I'd use it possibly?? I'll just put the 4.8L from the 04' in the 95 since it's my DD most the time anyways..

Here's a few details on my engine.

2005 stock bore/stroke LQ9
ARP rod/head bolts
LS7 lifters
Hardned pushrods
Ported/milled 317's
MS3 cam
TBSS intake
LS2 timing set

This is the stuff popping in my head so I'm sure there's some things missing.

Shouldn't be a problem.
We have several customers with 600+ DD.

So does "built" mean forged pistons rods and crank? Your parts list reads like a stock low end with rod bolts??

Stock pistons/rods I should have worded that different I guess..:D

I've had a few my bad:cheers:

hell boost the 4.8 and reach your goal lol!

What's the compression on the 6L with milled heads??

I've thought of that but I kinda want my 95 more ''stock'' just with an LS engine..




I was told they should be the same as 243's. But to be honest I'm not 100% sure:hmmm:

Bump for anymore suggestions:D

Your CR is going to play a big factor.

That's why I was thinking some stock 317 heads. I see that people boost LQ9's so with stock CR I should be in better shape.
