What would be the ideal exhaust size for a straight through exhaust creating the most velocity/back pressure?Stk 2.5" or straight through w/ 2" piping?

The smaller you go, the more back pressure you have - so with the information provided, 2".

What is stock?

Sorry,stock exhaust is 2.25" and im including the cat and resonators,I did a test by blowing air through different types of hose and it seemed that the smaller one "pulled air through whereas the bigger one just blew through it, leading me tp ask about a smaller exhaust size without any restrictions would flow way better.Opinions?Is it true for a car also.

stock is 2.5

ID or OD?I ask because the peice of pipe you guys hate me for was 2.25 and a perfect fit.Anyways a worthy mod?I am also starting to seriously contemplate F/I.
I am going to start stockpiling the parts,anyone know where to find a turbo header for the 4g64?Pacesetter?I will start by only running 4-5 psi to preserve the engine

when i customized the muffler on my car i bought a 2.5 ID pipe and it slid over my stock pipe, it wasn't all that easy, but it went on with some heavy encouragement (baby sledge hammer) then i welded the pieces together with a MIG welder and then bolted the exhaust piece back together.

now as far as turbo's go all you need to find is a 4G63t turbo manifold without down pipe. fabricate your own down pipe to go back the correct direction. your engine should be able to handle 8 psi and have the same amount of wear and tear as 4-6 psi will do to it.

I can possibly get a free used turbo but whats the biggest I can go w/out causing problems and is that 4g63t exhaust manifold a direct bolt-on?
Also what size intercooler?or does it matter?
Ill be keeping my stock SOHC head.

the 4G63t manifold i have read bolts directly to the 4G64 head. the reason why you need to fabricate your own down pipe is because the 1G/2G down pipe will point to the front of your car. now if you got a down pipe from a 1G/2G you can cut the mounting bracket off and use it to fabricate your new exhaust. biggest in amounts of what? i would suggest you go with either the 16g which i heard can produce up to about 18psi with upgraded wastegate, boost controller, and BOV. anyways. the 20G is a bigger version of the 16G and the 24G is a customized version of the 16G and it can easily push 32psi.

there is always the t3 turbo you can go with, but everyone seems to get the same thing with them the over heat and you get a glowing turbo in your engine bay. that is by far the sickest feeling in my stomach i have ever had, when i saw a glowing turbo.

then there is a option of getting a T4 or a T3/T4 hybrid. the T series turbo's seem to always have overheating problems if they are mounted improperly and you do not have a great intercooler, air dam, or hood scoop to help keep the turbo cooled down.

now when it comes to intercoolers i have never really researched anything about them so i can't tell you much about them. all i can tell you is front mount is the best, and if you get a intercooler is it best to match it according to the amount of boost you are going to push. if your only going to push 6 psi a normal stock intercooler is fine. if your going to push more than 8 i suggest you upgrade to a bigger intercooler. a stock ones dimensions are usually 6" x 12" x 1". a upgrade would be 10" x 20" x 2" and for more than 22 psi of boost go with a 12" x 24" x 3". name brand wise i have no idea. ask Rob or EMC about that.

I ask about the turbo cause there is a used one here at work that is perfectly fine, it is off of a ford deisel; The turbo reads AR .70 m24 and it is a Garrett.?Does that tell you anything?
Shoot,Im off work in 5 minutes,so Ill have to try and relocate this thread on monday unless i STUMBLE ONto a computer.
I may have to read that book from barnes and noble....

first of all do you think a ford turbo will match to a 4G63t turbo manifold? not all turbo manifolds meet up to all turbo's some have different sizing exhausts. especially when you go as big as a diesel truck turbo.

to tell you the truth i really think it would be a waste of money to try to use that.

the smallest turbo diesel ford motor is now the 4.4 but back in 92 the stock turbo ford motor was a 7.3 L i mean do you really think your going to be pushing even close to the amount of exhaust out of your little 2.4 to push a turbo possibly meant to handle 7.3L worth of exhaust? probably not.

i know a guy they call the turbo guru back in Utah who could get it to work, but without his know how i just don't see it happening bro.

i mean if your looking for a used turbo there are is a really great site that buys used turbo's tests them and rebuilds them if they have to. then they tack on a warranty for them the ones i see are for $325.00. well here, here is the link location.

anyways the 4G63t manifold is going to be the hard part. i mean if you want one for cheaper than that site is selling them for. just for a EVO turbo manifold they are charging over 6 bills. i suggest you ask Rob, ECM 3000gt, SC customs, or bobthecow. if they possibly know of a site or place that can get their hands on them.

also don't forget your going to need to upgrade your fuel delivery system if you want to push anything above 7psi of boost for your car.

anyways i hope that helps you out a bit

Why would you keep your stock SOHC? doing a head swap for a 4g63 head will make putting a turbo application on your car so much easier.

no it won't, the 4G63t exhaust manifold pits up to the 4G64 head no problem. how exactly does it make it easier for turbo application?

the little t at the end of the 4G63t means turbo just in case you didn't know bro.

I found a computer, The guy who is helping me rebuilt his f350 super duty auto tranny and built the engine/tranny in his mtsubishi mighty max D50, needless to say his truck beat my car both of them. He thinks I can turbo for under a grand,Im going to attempt it.I need a 4g63t manifold!Also other stuff any freebies or cheap deals are welcome,just link me a site,and w of a gain?ow muchhen I get everything Ill post some pics,But first how unreliable will this make my car 5-6 psi,Also how much gain?
Oh yeah, no I didnt think itd work but again its free.I wish...

I know that broseph, all I'm saying is even the N/A 4g63 in the 1g is alot easier to bolt a 4g63t turbo up to. bobthecow did it to his for a little bit while he still had it. But the turbo was crap so he took it off. And besides the 4g64 doesn't really have a "kit" that you can just bolt up to our engines. And if there is it's pretty expensive, moreso than getting the 4g63t turbo off a 1g or 2g and putting it on our cars along with the head of an N/A 4g63.

All I'm trying to say.

With the manifold I think I could do the same thing<it depends on the cheapest route + Im in no hurry, A good deal is what Im looking for.They dont make a name brand turbo kit and on the occasion you can find one they are ridiculous in price,Probably because they see the potential outcome of turbocharging 2.4l to be a threat in some way.
How sure are we that the 4g63t manifold will fit?Are the ports even close in size?

I dont know how to paste and cut but the part number of the pace-setter exhaust manifold im looking at is 72c1225 or the 70-1225.Question is will it fit?

I would advice against it.

Pacesetter is the worst brand ever.

Wait about 2 or 3 months... it'll warp.

Would a stk one off a 1st and/or 2nd gen eclipse gst-gsx fit?
