The Project Pad

I decided on 2.5" for my 20v with turbo upgrades in mind. It won't choke it up until 400 horse and be much more liveable

Im eventually going to have a 3" down pipe made. Most likely next summer. I was told to open it up from the advice of Scubadave who had a very similar setup to mine. If it does drone, I'll throw a resonator underneath if it is bad. My truck has dual 2.5", balance pipe, the whole shebang. WITH the most aggressive, loudest street mufflers Spintech makes. Very little noticable drone when cruising, nice idle, and holy freaking hell when on it. This muffler for the car should minus the effects of the bigger pipe as far as noise goes

True that. I understand you like that brand of muffler I hear ya.

I meant as more of a performance standpoint, if it ever gets a header/ turbo setup and efi you'll be glad 3" is on it. In stock and chipped form there is no need for 3" pipes behind a k24 or k26. Sure will sound good though

Yeah it'll get EFI soon enough. Winter is here so I have to focus more on the car being a DD now. No more modifications!!! I've done enough over the last 7 months. It's alot more than stock too.

17psi, 34mm exhaust valves, ported head/manifolds, good free flowing intake. And that Ben Swann chip which might be getting switched out for a natrix

I think the question should be why not go 3"? If you are building a complete exhaust for a car that is more than just a stock DD then its a no brainer. this aint no corolla.

Ehh alright I gotcha just thinking out loud.

I went 2.5" maybe ill kick myself in the bum later.

I feel free flowing 2.5" will support as much power as I want that's all

2.5" is fine. I just feel trying to run 3x the air through a factory setup will create limitations

What if the corolla had shit subs, a giant useless wing, body damage, primered black hood, and a 3" exhaust dumped into a 5" folger's coffee can muffler?

Then that would be one sick corolla and I want it!

Omg, theres a chance of snow on Monday and Sunday!!!! Anyone in the market for a wrecked Dakota R/T pickup? Lol. Car should be completely streetable next week

Get it done!!!

I need a clutch for mine! :(
You're teasing me! :O lol. I just want mine done.

And get it done

So I'm thinking 4 degrees advanced on the cam should clean it up nicely. Thoughts?

I don't know if I would jump that far right away. Start at 2 and see how it acts.

:stupid: 4 degrees is quite a bit of advance.

2.5" is a restriction even at 300hp. For a stock 3b or Chipped MC, 2.5" is really the minimum. I noticed a noticable improvement in spooling on my 5ktq with 3" Exhaust. The 91' 200 had dual pipes for a reason, FLOW. I dont recall the exact numbers but dual 2.5" has more flow capability than a single 3". Actually, dual 2.25" Pipes are pretty close to a single 3". Most of the stuff I've read puts a single 2.5" System at around 225 - 250hp max. Sure, you can get more power out of it, but your losing out on available power to do so. Especially with a Turbo Engine. They just love to be Open.

:stupid: Especially on a Turbo setup. And especially if you ever plan on doing anything more with it.

Whatever not here to dispute, that's what I get for putting my 2 cent in

Jonathan, nothing but friendly input of personal preference and knowledge going on here so please don't take it personally. We all have our own ideas of things should be, but your .02 is just as appreciated as the next guys. Please continue.

Ok good news and bad news. Turns out, it is possible to wire the 5ktq multi-function temp sensor into the 4k dash. My coolant temp display now works.

The bpv is finally plumbed up. It works very well and increased the idle vacuum to about 10".

Bad news. If I now turn on the parking lights (position 1), the car will die!!!

Omg.........thoughts on this?

Omg false alarm.....I hope. Turns out the fuel dizzy was way too rich. Im assuming that when I put the load on the alt, it would be too much for the engine. Whats weird is that everything else including the fan wouldnt kill it

God I hate cars. Maybe Ill just go back to playing video games

how are you tuning the CIS? Might be time to have a CIS tech tune it properly.

Bah. I dont need no damn tech! All you need is a dwell meter lol. But no, it will get properly tuned when I bring it to the dyno

Good. I want to see what kind of #s this puts down. Will give me an idea of what to expect.
