232whp, 218wtq version TRM tune rocks!

I bought my hoist used for $80 off craigslist. Harbor Freight has em pretty cheap too if you want new. (that's where I got my stand from)

Sorry for being a little OT, but I noticed your sig. You have a turbo to make that kind of power with an M20, right?

it also says that its a 3.1L...

[mazur]

Back pressure is never a good thing, its exhaust velocity that helps with scavenging. Big exhausts lower exhaust gas velocity thats why they can lose power at low rpm.

Oh and it also appears the S52 put down 232whp with either a warped head or leaking headgasket.

Yay for pulling the motor and exchanging it.

That really blows, sorry to hear that..

[z31maniac]

OOOOMMMMGGG. So sorry to hear it dudey... Plan on doing it asap or when things calm down with the house and winter starts?

I'll probably try to get it pulled next week. I need to buy an engine hoist as the one I was borrowing from my buddy was a piece of junk.

At least now I have a garage to do it in!

Don't the last Gen Camaro guys run a single 3"? With a fucking 350 V8? How a 3" could be a good thing on a Honda 4 banger I have no idea, even FI on a 2.0L a 3" sounds too big.

There has to be some backpressure in the exhaust to help with scavengeningng.

That seems counter intuitive. Would you care to explain your reasoning? The problem with too big of an exhaust would be the loss of exhaust velocity, would it not?

And my grasp of fluid dynamics is feeble, but it would appear that his exhaust flows significantly less than stock piping would.

There are a lot of good N/A tuners that work with Hondas.

running euro headers, euro midsection, stromung catback.

english, please :)

[MIKe30]

we'll if single 2.5" is ideal for these motors then I'm in trouble... running euro headers, euro midsection, stromung catback.

[Jonny Cash]

Does the term "exhaust scavenging" ring a bell? If not, you should do some reading.

fwiw, I would guarantee more TQ loss than hp gain in the said setup going with a wider diameter. Not claiming to be a physics whiz, just sayin.

Indeed.

Of course there are. But there are also the guys running full 3" exhausts for a 160whp B18C1 (I knew one of them).

[Mr Two]

No, definitly not too small. Anything more than that will create backpressure.

People do alot of retarded things

Especially in the honda scene.
