Lets talk Custom downpipes.

Thanks for the reply. Yes i already have the jays racing relocation kit. http://www.dsmtuners.com/forums/blogs/1fastlaser/448-my-push-limit-build.html#comment2598

Thats my build blog. I have alot of the stuff taking care of. Even all my new "push lock" vacuum line setup which i have to take pictures of. I plan on using a bullet muffler of some sort, and ofcourse the same size. Looking into the magnaflow shorty race mufflers.

I am thinking about doing the same thing seeing how jake did all the work with the SS vacuum lines. makes for a leak proof cleaner setup.

You can weld stainless to mild steel using a normal mild steel welding wire with a normal multi-mix welding gas. I do it all the time. If your getting it coated you wont have to worry about the weld rusting anyways. It wont crack either.

How about an aluminum exhaust, that would save a heck of alot of weight espeically in a 3.5 or 4" size. I guess since you said money is tight you wont be doing that.

Vbands are great for downpipes/exhaust/intercooler piping etc. I do all my exhaust with them and it makes it incredibly easy to remove and install. Plus not having to worry about leaks is a plus.

Goodluck. 3" dp to a 3.5" exhaust will be fine. Use stainless if you can swing it, if not just get it coated. Vbands are a great idea too.

well started to put the turbo on, and ran into the fitment snag. How are guys taking car of the compressor outlet/motor mount issue? I was thinking about reversing the turbo, or putting a honda radiator in. But i read there is ways to take car of it.

What manifold your using? Some manifolds were only made with a T04S housing at most in mind and just can't tuck a gt4294 sized turbo up underneath properly.

its worked out, im picking up a scirocco radiator to open up room for the outlet of the turbo between the motor mount and radiator.. The manifold is the On-green performance one, and as i posted in the picture of the 2g is running that manifold turbo setup, 2gs just have the motor mount out of the way.

The radiators 250 bucks but shit i gotta do it, so im ordering it NOW!

I don't know if you have gathered your materials yet but i would opt for 304. If money is tight and you get mild steel i would get it coated by swain tech they do nice work and we have had a few of our customers had great success with them. I was planing on coating my manifold but decided to just wait until i make my new manifold and have that coated.

the afco scirocco radiator will give me the room i need to angle the compressor outlet more forward.

Looks good I too will be doing a "pie cut" DP. Not to excited to start it yet though. I did put my alternator on the back of the block. But doing a side exit is not really an option either. I want it to stay cop friendly ish. Still use my qtp cut out.

If memory serves correct the white "extreme" talon went 8s with that manifold. I cant remember the name of it but I have the Dsport article somewhere.

My manifold is the HKS copy On green performance.com makes. I ordered the Afco scirocco radiator today so soon ill get this thing going, i just want to get this downpipe/exhaust done.

I think part of the problem is your tubular k member I think is the correct name for it(the bar that your front engine mount is connected to.

 

[diambo4life]

Would have been much easier building a top mount header instead. Big frame turbos + bottom mount headers in a 1G = NIGHTMARE. Maybe on a race car...but not a street car. I personally don't like changing everything else to accomodate my turbo. I prefer making/having a header that will make my turbo fit in my car as is.
Good luck and keep us up to date with your progress.

Acually the k member front bar is going to help alot when the New radiator is in, ill probably have a 1/4 of a inch or more room between the bar, and the chassis cross bar or whatever that is. I was searching some post on other forums, and even they said and did this radiator setup with top mounts to make life easier 2 of which were evileagle, and eagleclaw, and got 60' which did a 4294 with a dnp manifold. Its virtually impossible without it. Plus is makes 3" intercooler pipes fit alot easier also.

Or you could ditch that manifold and get the JHR manifold that boosted is selling. I talk to him prett often and I know he's looking to get rid of his because he wants to go a different route and Jake designed them to run gt42r and s372 sized turbos. I should know I own one not to mention it's a whole lot cheaper than going top mount.

T4 Divided Exhaust Manifold 4G63 GT42R / GT40R


And new he only charges like $859 plus shipping too.

Well unless he replys and changings what i beleave. Im sure his manifold fits a gt42 and same as dnp, BUT the motor mount/ radiator will still be an issue with the outlet on a gt42.

GoT 60' project car - Page 2 - DSM Forums: Mitsubishi Eclipse, Plymouth Laser, and Eagle Talon Forum: DSMtalk.com

he had to go with a afco scirocco. You can see all the room that opens up with the factory radiator out of the way. I dont care if theres another manifold that "almost makes it fit" i can see with my eyes theres hardly any room, might as well make more

WHo said anything about almost fitting

The top pic is Jake H's car with a gt42r/s372 not sure which on on with IC piping hooked up and the second is boosted's car with a hx52 just about the same dimensions mounted and IC piping hooked up with the same manifold I"m talking about just one is a dual 44mm vband.

Look closely at Jakes radiator . Afco scirocco. It wouldnt fit if it wasnt there. You can also see the ic pipe if you look closely.

As for the hx52 ofcourse that fits, it dosen't have a 3.5 outlet

Your right I didn't even look at the radiator. Well even more reason you should have just got a a hx52

Yeah yeah i know. But shit everyone upgrades there radiator, mine just happens to make more room also right?! I dont know if my stock radiator will keep up with 36psi and top speed runs while wooping busas ya know

BUSA BUSTA That's how we get down in South jersey I don't have a radiator yet either I might just get one for good meausre.

Might as well, i mean your going to buy a radiator anyway, might as well buy one that gives you room. I also need it to make the downpipe easier to make.

Im going to be ordering pipes this week. It sucks because alot of people are give and take for bends and flex pipe sizes.

 

[caliboy23]

I'm going to be mounting up my T3/T4 50 trim next week. So in order to make things easier I decided to go with only 2.5 piping off the turbo and open up to the 3 inch just above the oil pan.

I've actually seen lots of high hp test cars. All of which are turbocharged running only 2.5 piping all the way to the back of the car. In most cases the sound levels drop by a very noticable amount while peak hp levels only fell off 5-10 hp. One of which was a 1000 hp 300zx that only lost 7 hp.

 

[1fastlaser]

Got ya, A good friend of mine has a 3 rotor rx7 with a borg s488 on it, On 13psi he picked up 14hp and 22 ft lbs of torque going from 3 to 4 inch exhaust. Im going with a 3.5 inch exhaust since the outlet on the turbine is 4 inch, and 3.5 will fit easier with little loss.

I had some problems finding a place that sells all the pipes i need. Summit has most of them, but no 3.5 flex section, and i need a 3.5 v-band kit and a 4 inch v-band flange. Ebay has the v-bands, but no flex sections . Im going to be ordering little things from all over its annoying.
