wat kind of throttle bodies are you guys running on LS6 Intake?
plan on getting ls6 any suggest for tb?

 

I got a stock ported Z06 for 65$ off ebay.

 

Ported stock tb.

 

hmm is there a difference in the ls1 and ls6 TB? and whats the largest size the ls6 can handle? or what size is it?

 

the 97-02 LS1s used cable and the newer ones used drive by wire. The LS6's used a drive by wire throttlebody. The size is the same however, which is 78mm i believe and is all a LS6 will correctly accept. Unless you buy a BBK setup which has a plate to run a 80 or 85mm.

 

ok so the ls1 throttle body wont work on the ls6 intake manifold?

thank you all for you help

 

It will work fine. I sell ported throttle bodies and have a few on the shelf right now.
The only difference I see is the cooling tube angle and the size of the guide the throttlke cable attaches to.

 

pm sent to blancoSS on info regarding pricing for ported TB's

what kinda of mass air flow do u recommend for the LS6?

 

Stay stock MAF unless you go 90mm or better TB and even then the gains are debateable. Aftermarket MAFs can be a PIA to tune sometimes.

 

cool thanks for all your help

 

this kind,,,

 

wow cool is that for sale?? lemme know

if i did put an ls6 throttle body on my 99 z28 with an ls6 intake what would i have to change? the linkage or anything? can it use the same fuel rails?

Thanks!

 

No changes all the same.

The EGR is what you need to think about the tb is direct swap. If you buy an LS6 w/egr then your fine as well, more expensive look, for a used one. BUT if you eliminate the EGR then you can use the cheaper verison of the ls6 without the egr setup.

 

i just bought a used LS6 for $275
the p/n is
12573572
is that any good? does it have an egr? guy said it came off a trans am? but i googled it and i think it came from a Z06

any info on this specific manifold? like problems? common issues?

 

I found this in a search, not sure how accurate it is.


I dont think there are any issues, its just the EGR thing at this point for you. If your car is equiped the intake isnt you need to get rid of it from your car or modify the intake.

 

cool thanks for all your help!

 

Got my Stock LS1 TB on an Ls6 intake...Dyno numbers in sig...I'm content.

 

ok so i have a stock 99 z28 ls1 im putting in an LS6 p/n 12573572

am i gna need an egr block off plate? does that specific manifold have it? i wanna do be able to put it all together this weekend but dont wana get stuck and have to order a part. its my daily driver.. i also heard something about the cooling lines being in the way?

thanks!

 

oh and if i did remove the EGR would it still pass smog? i live in CA

 

CA = you need EGR, you will not pass emissions.

the manifold you got has the same stamped number as the SLP LS6 intake i got. Its a z06 with EGR provisions.
