so i just finished the second ported and polished throttle body and these things are turning out amazing, i grew up around race cars so i kow what im doing and how to do this properly..well im just trying to get a feeler on how many people would be interested in one im going to sell them for around 90 bucks with a new gm gasket and your throttle body in return they are alot cheeper than the saturn motorsports tb and on a dyno they added 5 hp at the wheels on a stock cobalt i havent dynoed my car yet to see what it would do on a modded cobalt but 5 whp for 90 bucks aint bad at all ....... ill post pics up tomorrow hopefully

 

I'm totally interested in this if you'll wait for me to install the new one before i ship you my old one And i've never really done a tb install or messed with one what's the difficulty like?

 

for 90 bucks shipped I'd be down...

 

i would be very interested, only problem is i cant be without my car. So sending my TB out is not an option...

 

i would buy one but i would need to isntall it before i send you my stock one. also IBFTL

 

Here we go...

Get the dyno graph when you do it.

Also, what is the size now?

 

Yeah, i would like to see the dyno sheet, would be a nice addition for the NA guys. Also, is there anymore room to port it when tuning becomes available. Actually i guess we could just throw the 2.4TB on there with a retune eventually.

Installing a new TB is very simple. You remove your intake, and its 4 10mm bolts i believe? i cant remember the exact size. You then remove the Throttle wiring(very easy clip to take off) and your done.

 

yea, dyno sheet, and checking it in the car to see if it threw a CEL.
I doubt it would...but god knows with our ECUs.

 

any pic i want one of these. this would go good with the 2.4 mainfold swap crate engine depot has

 

stupid how?......subscribed

 

dude ^^^ read what you just posted

 

Lets open this beast up. Dyno or death. J/K i'm not a serious person. Everyone just wants to know what the point is before we drop a Benjamin

 

ill look around work and see if i can find a throttlebody laying around

 

The point is your making the throttle body bigger so your allowing your engine to pull in more air. The problem is, if you open it too much, you will throw a code and/or throw it into limp mode because the car is seeing a huge change from what its use to. With tuning you can really take advantage of a larger TB.

 

ahhh, the fact that theres no tuning for the 2.2 is really starting to get to me now. At first i was just annoyed but now im pissed. Somebody do something!!!

 

its 2.75 inner dia ill post pics up tonight or tomorrow

 

Funny....I was going ask about having it flowed. Back in my previous life of hot rods we'd send the Holley's out for a flow job for huge gains. I'd like to see some pics...tnks.

 

i going to try and get pics up tonight if not ill do it tomorrow.....i have to wait for my lil sis to get home she can post them up since i hate computers and dont want to learn anything about them......but yeah im going to post them asap

 

Very true, if you just go at it you will cause a huge vacuum leak and set codes. The secret behind porting a stock 2.2 TB is not to enlarge the actual throtle bore itself. I snagged a spare from work off an engine job and set to work on it myself. Go to your car remove the intake and prop the throttle blade open. Feel the inner contour of the TB on the portion closest to the front of the car. There is a hump machined into the TB that shields the throttle blade opening from getting straight airflow at low angles. I removed that hump from the spare TB that I had off the car, very important. Without touching the actual sealing surface that the blade touches I removed material untill it was all smooth. I cant prove a differance but I can say the car does feel like it has more low end power, call me crazy

 

My TB along with a lot of other parts of my engine are sitting in a box right now, im gonna go look at that hump you speak of. I would have that removed too but i dont believe its going to effect my low end when using FI.

 

 

It was my understanding that the 2.4 TB wouldn't work because the computer couldn't understand the diffrence in airflow. But it would appear if this works, its in the electronics, not the airflow.

Please Dyno this, I'm definatly intrested to match this to my 2.4 manifold swap.

 

ill see if the kid still has his dyno sheet.....but next weekend im going to dyno mine granted its very modded ill let you know the gains.....it feels great with the 2.4 mani swap btw

yes the 2.4 electronics are completly different from ours

 

Looks good...you can pick up quite by eliminating most of the bar thats holding the plate. This requires some minor welding/brazing. Probably good for your modded engine or a SC but not a N/A stocker.
