i'll apologize in advance if i've missed this info in a thread.
I don't suppose i can put a throttle body from an L67 on a stock L32, can i?
secondly, if that was possible would the porting be the same for both the L67 & L32?

Nope, The L32 is an electronic controlled TB (drive by wire) and the L67 is cable operated. That's just for starters, the bolt patterns aren't even the same.
07-30-2010
And make it less efficient? Aside from what Reptile said, the L32 bore is about 75mm already L67 ported I think is what, 72mm tops?. There's not much else you can do with it.

Tossed around the idea of putting a bigger LS1/LS2 DBW TB awhile back...but no one had access to one to test it...thought it would a pretty cool idea for the '04+ guys that have no TB options...pretty sure the bolt pattern is the same on them.
07-30-2010
I had the exact same idea. I threw around the idea with one of my buddies who has a CompG and I guess he was able to go to a local dealer and handle one for a vette I believe to compare differences. From what I can tell it's a similar bolt pattern, and if not, there's always adapter plates. They have different connectors for the harness, so it would require some work there as well. The only real problem I see is there's not much benefit from a ported GenV blower and the stock TB is port matched already.Originally Posted by bluegtp91

Thanks guys. I appreciate the quick feedback.
So, can this TB be ported and more importantly, should it? NinnyGTP you implied that stock is the best i can do.
I appreciate your time and feedback!

Not really...if anything I guess you could smooth out any imperfections in there but those are probably pretty minimal if at all. Put your money elsewhere before bringing more air into the engine via a bigger TB...that will only help you after you drop to a smaller pulley and are running a cam, intercooler, or high ratio rocker setup.
07-30-2010
good stuff bluegtp91! I'll scrap the TB idea.
in your "safely modding your 3800..." stickied thread you suggest porting the LIM. I've been thinking about doing that next and then switching to a 3.4 pulley. any suggestions on the order of importance?
07-30-2010
Just food for thought, I'm running headers, tuned PCM, 180 thermostat, and autolite 104 plugs on a 3.6 and I still see some kr here and there. I have a feeling you're not that modded yet so I wouldn't even think about a 3.4 until you have the mods I have plus an intercooler and/or cam
07-30-2010
I thought i might be pushing the 3.4 idea a little too soon. I was relying on someone more knowledgeable then me to point out my error. Thanks oh4compg.
question: did you do the tuning yourself?
07-30-2010
What year car do you have? If it is an '04 or '05 you can still buy a canned tuned PCM fom 3800performance.
07-30-2010
i've got an 04 gtp compG.
i've read posts that bagged on the canned tuned PCMs. however, now that i think about it they may have been baggin on zzperformance's canned tuned PCMs. alright man, i'll look into 3800 perf's PCMs. i've got nowhere to go but up with my modding...
Thanks for the advice bluegtp01!
BTW, you guys have really taken this thread in a different direction. Good stuff!! always learnin'
07-30-2010
You'd also have to consider that the wiring needs to be the same, and I would imagine the volt references to open/shut the throttle blade. Maybe they're all about the same, but I'd hate to have something go wrong, and the TB open up all the way without having any control over it. IMO I think the 90mm would be way overkill for it anyway.
07-30-2010
Right...but I'm talking about modded folks...like tiny pulley, big cam people...when you've totally run out of crap to do LOL
I think it would be worth it...and then open up the inlet of the GenV to match the bigger TB
07-30-2010
If you're gonna open things up that much, you might as well go the full monty and turbo it.
