1996 ported throttle body

hey guys on zz performance I was wondering if this would work for my car?

Sure, it'll fit - but don't expect your car to break into high 12 second track times, as they claim.

Wow. 1/2 a second faster for $200 bucks.It doesn't sound cost effective

No, it's a steal. With this mod you will run high 12s.

Holy shit. It actually says that....

Lol well is it only for the L67 be ause I could use this.

wow I didn't even notice that, I just wanted it to turn down the knock a little bit haha

LOL

Do you guys know if I can remove the screen on my stock throttle body?

I have a 95 SC Riv.

You mean the round mesh screen? Yes you can, there's a retention ring in front of it that you can squeeze and pull out and the screen follows after it. Make sure to put it back in after you're done cleaning or porting or whatever. The screen is not a negative cfm factor and offers increased air stabilization and additional crap filtering from anything that's made it that far downstream.

It's an inside lock-ring that holds the honeycomb in place. Usually, if you're careful, you can get it out with a small screwdriver. Otherwise (in rare instances), you'll need inside lock-ring pliers.

IIamalor is right. Do NOT remove that screen permanently. It absolutely smooths the flow of air across the MAF and prevents swirling. It actually has more negative than positive affects when you remove it.

The screen just seems so counter productive but you guys know these cars better than I do so the screen is there to stay.

Do the high flow aftermarket TB's come with the screen? Would I have to swap the stock screen into the aftermarket unit?

It doesn't look like it comes with a screen. That being said, if you're seriously considering that ZZP throttle body I would have to advise against it. You can get a N* setup for around the same price (if not a little more) and you will be better off (N* is 75MM vs Stock L67 69MM, Ported N* 80MM vs ZZP L67 72MM).

You can pick up a used N* for between $100 and $150 with the MAF, and then another $100 for the adapter plate. The only downside is that you need a tuner because the MAF for the N* uses a different  table than the L67.

Edit: Also keep in mind that most M90 port jobs don't go much above 75MM.

Sorry, I'm a newbie to the Supercharged scene so you're gonna have to explain to me what a N* is?

Are there any TB's that are direct bolt ons that don't require a tune for my 95?

What about those Eprom plug in chips?

ZZP sells new full kits for $410

N* engines are a dime a dozen. I dont understand how hard it could be to find a used TB cheap. What years are ideal for the Series 2 Rivs?

N* is a "Northstar" throttle body, a similar one to ours from a cadillac V8 of the same era. It's not identical though, that's why the adapter plate.

However, it says in your signature that you have a '95 S/C - and that means you have a series I 3800, not a series II like the 96-99s. And that means almost none of the mods we are discussing will fit your car.

Leave that screen in place. It straightens/smooths the airflow so the MAF sensor gets an accurate reading.

Yeah, but look around. You can find people parting out their cars and getting rid of them for next to nothing. You can also pick them up from junkyards for reasonable prices. ZZPs kit comes with everything you need, but you would save a lot of money buy buying the actual throttle body and MAF elsewhere.

Yes, but we refer back to deeksters keen eye in noticing that he has a '95. N* kit won't work. Neither will a ZZP ported.

True, true. There has to be something that can be done for a 95........

I guess I'll have to settle for an intake and a new exhaust system.

Any suggestions on mufflers? Should I delete the resonator? What size exhaust piping? 2.5 inch?
