has any one done this? my friend did it to his 2.2 and it really woke the car up. i was thinking about doing it.

 

If you are interested in this service let me know. We work with a local machinist who specializes in throttle bodies. Here's an example of what he does to a stock TB on the LT1 engines:

I would need to check with him for pricing for the LNF throttle body.

 

o wow thats nice...what kind of gains are expected from porting the TB

 

Mmmmm... not sure how it would work on an LNF. The computer likes to compensate negatively for extra airflow. Now, if HPT unlocked the whole ECM, then we might be able to tune that out. But until then, I personally wouldn't feel comfortable doing an irreversible mod to a piece that would cost so much to replace.

 

thanks but no thanks ill do it my self case im broke
thats what i was thinking about and also i herd of someone losing 10-20hp on a dyno from this mod... but also this was about a year ago and hpt has came far from then

 

Actually, HPT may have come far, but not quite far enough. There is a thread that ZZP made about putting on a bigger TB, and I imagine the result would be much the same. The computer compensated for the airflow and closed the throttle plate some.

 

could you post up a link or the name of the tread id be interested in this

 

Ah... I just saw it last night. Lemme see if I can dig it up.

Found it.

 

u are a god my friend a god

 

Lol, I try. Its a very interesting thread. I think the majority of it is speculation on why the computer does what it does, but it will give you an idea what might happen if you do the TB widening. I mean, it might work, but I would HATE to waste that much time and money if it doesn't work.

I would like to see if polishing the TB would help at all. It would be a first step in the right direction, but until we can completely disable limp mode, I don't think we will be able to change a whole crap ton on the car.

 

Money is better spent elsewhere, getting a bigger throttle body on a stock turbo is kinda pointless. Maybe when you're pushing double the power and you pretty much did every bolt on than a tb makes sense.

 

i guess you didnt notice im not stock

 

I would be interested in this on an LSJ, if the gains are decent and the price is right...

 

When I had a PGT, we did this all the time. Of course we converted to ZE engine and bought a JDM ECU that upped the fuel output. Dont ya just wish it was that easy to fix the fueling issues on the CSS?

 

My reply was to the OP not you, but even with your mods i still wouldn't waste your money since you're not pushing any serious power. Simply up the boost and you'll get more power.
This mod works totally different on naturally aspirated cars than turbo cars since the air is heavily compressed and opening the throttle orifice a bit isn't going to matter much.

 

X2. faster airload velocity FTW. Bigger TB might matter on a GT40R equipped Balt.

 

I haven't had any TB's for these car done. It's just a service we have available but not something we have had very many requests for outside the B-body community.
