3.5" Pulley/ Exhaust



Thanks guys. So i'm going too get new headers. Upon getting them installed i can look at getting a 3.4" right? How much do new headers cost figurativly?
 


A tune changes the perimeters in the pcm to allow for more fuel and timing, a custom tune from a local guy would be best or you can buy a canned to from the 3800 vendors, the dhp tune is one of the safest you can run.
 
lol yeah, i dont care how stupid my questions may appear to be; better askin you guys then a live audience. Today i went to KarBelt auto in Pickering Ontario, and talked to the guy about putting a pulley in it. He was suggesting that the exhaust has nothing to do with the pulley, and it isn't necessary for the car. My car has a 175000 clicks on it and he suggested that adding new performance parts may not be worth it. I don't agree with him, but he's pritty confident in that a) i can just put a new pulley accompanied with a 160 degree thermostat and the car will be fine b) that i shouldn't get a tune because it the ecm is a closed module, and because it ain't recomended by G.M it isn't worth the risk. What's your take on this guys diagnostic's?
 
I thought a regular said "boost stacking"... sorry about that.

Why would you not just go see korey at karbelt down on simcoe?

Oh well.

If you're in oshawa, I REALLY don't see why you wouldnt just have Will tune your car.

In car tune with a wideband for $200, $50-100 for a retune if you chose to keep modding.

This isn't a SBC where that WOULD be considered the correct modding path.

Which headers are you getting?

Who is doing the header install?

If you need help, gimme a shout. I'm not far.

Well start with the 3.4 pulley as it usually starts the majority of these questions. Below you will find a list of supporting mods that should be in place prior to installing that 3.4. Can you get away with less? Possibly. Have people gotten away with less? Yes. Do you want to take the chance? Enough said.

1. PCM- standard v 1.0 will suffice at this level.
2. CAI/FWI- Cold Air Intake/ Fenderwell Intake, you can build your own or purchase one from a vendor.
3. Ported Exhaust Manifolds/ Headers/ ZZP Powerlog- your choice, at this level Pems or the Powerlog are fine, if your planning on further modding later you will need headers, only you know your budget.
4. 3" Downpipe- Crushbendt which most exhaust shops will do is unadvised, preferable to purchase an aftermarket from one of the vendors.
5. 1-2 Heat range colder plugs. i.e Autolite 104's or equivelent gapped in the .050-.055 range
6. Ubend delete- just after the cat, most exhaust shops will be able to remove this and put in a straight pipe.

Thats it, doesnt sound too hard right? Fortunatly your reading this, back when alot of us blew our motors there was no such write up and no such guidance. These 5 items are considered necissary, of course you can change your thermo to a 180 unit, also wouldnt hurt. Also quite a few people add a set of 1.9 ratio rockers to that list. If you plan on staying at this mod level, I agree, add the rockers, if your planning on continuing on in the quest of more speed and wont be at this level for very long skip the rockers.

thats what I would do 3.5 or 3.4
 
1. Will is around the corner.

2. Indeed.

3. the cat will play a huge role in the cost there.

5. These can be tricky. But most speed shops should have TR6's. I know karbelt on simcoe does. 605's might be the right plug though.

IMO I wouldnt run a colder t-stat. I know that most people on here will disagree but i dont see the point. heat=power.

Wut? Then I guess that means its pointless to ice your car down before/after you make a pass. Also that means that you will run better times if you run your car back to back nonstop and get better times. Also means that an IC is absolutely pointless.

Will you explain your reasoning behind your comment?

And every car is different those listings are if you are paranoid as **** to run a smaller pulley. LOL

What's funny about boost stacking?

The fact that it is a horrible term for an engine not flowing very well.
