I've got a 99 TA and fixing to put a sts turbo kit on. Just trying to find some info on heads and possibly cam on a budget. The reason for the budget is a stroker in the future, but anywayz. Are the lq9 heads any good, and I heard that a 02+ ls6 cam is good for a budget boost cam??? Any suggestions would be of great help.

 

317 heads and ls6 cam is good for a budget build..

 

I have made over 800+rwhp with them several times.

 

What kind of setup for 800?

 

more than a strict budget will safely allow..

on a small budget built correctly you will be looking at about 450-550 max, depending on the money..

 

the whole point of getting the lq9 heads is to drop the engine's CR to run boost more safely. they also flow a little better then the stock ls1 heads.

 

See my sig.

 

I've got stage 3 patriot LQ9s

 

Also how much do these heads lower the compression? How much more boost can you run safetly? Thanks for everyones input!!

 

ttt...

 

TC76 Turbo
8.5:1 370
LQ9 heads
918 springs
TU1 Cam

At 15 lbs it made 770rwhp.
At 20lbs it broke 800rwhp.



450-550 max is a friggin joke, We do that on the stock long block at 8lbs and pump gas.

 

I had good results with them. Probably could have made over 600rwhp if I didn't have a fuel issue. Im going to use them on my 402/ F1A build and see how they do. Numbers are in my sig.

some where around 9.5:1 depending on the head gasket. and i personally would not run anything over 10 psi on my short block. good luck

 

strict safe budget..... maybe my opinion on safe and strict budget is different from yours?

 

Budget doesnt change. Only the tune from Safe to Ready To Blow. Opinions very. This I know. If you want to tune your setup to be safe at 450-550rwhp that is totaly cool. I can safley make 550+rwhp. Its all in what you want.

 

well honestly.. thats just what i have seen..
i know you know a lot more about turbos than i do..
jason has told me you know how to put your **** together..

i would just think after 550 or so, then you would need injectors, fuel pump, etc.. and thats where the "strict budget" is starting to get stretched a little..

i dont know much at all about turbos.. i like N/A, and a little bottle..

 

You should be able to make 500 + pretty easy. I made just under 500whp in my 5.3 with 10 psi.

 

I just recently turned my boost up to 15psi and and so far so good.
I am running 317's that I ported a little with arp head bolts, 48lb injectors, 340l pump and pump gas with no meth and on a built 10 bolt. I am still running 10.0 afr and no knock to speak of. I dont plan on going any further on my stock 113k bottom end as I am pleased thus far. I am blowing through the convertor now that I raised the boost 5psi(4l80e).
Oh well time to upgrade.

Trying to test the limits of componets and proving it can be done with a relative cheap setup.

 

how are you running 48lb injectors at 15psi with AFR of 10.0 your was that a typeo ? not flaming here just looks wrong is all

 

ive made good power with 317s but as far as boost goes i 12psi on a stock short block and its holding up well but its all in the tune
i think it would run better with less boost and a tune change (more timing and less fuel )
i say get 317s run 8-10psi with some meth and a good tuner you can make 600rwhp easy
my ride has made 694rwhp with 317s and ZO6 cam at 12psi but we turned it down after that LOL
hope this helps
