Inline 250 - T3 Turbo - w/ Video

[vivisix]

love turbos. that thing sounds sweet. nice job!

I got around to tuning it a little. I also put a magnaflow performance muffler on it with 3" and it turns out flush, right in front of the rear tire. It sounds deeper and not as much turbo whistle, but it still sings under driving boost. I re-jetted it down to 66 jets with a 4.5 pv. It seems to be running leaner and better ( I think I was running really fat earlier ) I will try to post a new video with the new exhaust.

Ghostwhite - go for it. It is important to get the right turbo, plumb it right, get a good condition used 350cfm Holley 2 bbl and make it blow thru. All else is exhaust routing. If you have any questions, ask me. I'll walk you through it. I've got pics documenting the whole procedure.

"...used 350cfm Holley 2 bbl and make it blow thru." What is that? Pull the choke plates out of it? Just curious.


BTW.... KICK A$$ PROJECT!!

Taking the choke horn off is part of the blow thru mod. There are a few others that seal it up to allow it to accept boost. This is the best link on how to do it:

it seems overwhelming at first, but its quite easy.

The engine rebuild has started. I was tired of oil shooting out of my oil pan caused by worn rings and blow by. I am going .030 over, turbo spec cam, stock internals, hogged out intake to accept holley 2bbl, HEI and these :

new old stock Forged TRW flat top pistons. hard to find item

here is an updated pic of the engine bay. I had the engine rebuilt with .030 over forged pistons, Lunati turbo spec cam, new internals. I hogged out the original intake to accept a 2bbl Holley. I will be adding a HEI unit. I am really excited to fire it up soon.

Nice project, I cant wait to do this to my 230 someday. Keep up the cool work!

I finally got a chance get a short video of the turbo attached and a short idle / rev. It sounds so much after the engine rebuild.

enjoy!

i would like to see how this turns out...like it so far..good work

I am hoping that by running a DEI titanium heat shield over the turbine, and DEI titanium wrapping the down pipe and running a 3" downpipe with less turbine back pressure, in addition to the meth injection, I can limit the effects of heat soak. With the smaller down pipe and having extra exhaust piping setup under the hood like you do, and if you are already experiencing heat soak, you might want to run an intercooler. Also how many core radiator are you running? And did you check your setup with a wideband or plugs, because if your running too lean or too rich you can run way HOT. Since you have everything tore apart right now, I would also consider wrapping your up pipe and down pipe to help push the heat out the tailpipe.

And your 100% right about turning up the boost.... I suppose that's thats always a project for down the road... 4 core intercooler and 18-20lbs of boost....

Disregard, I found all my missing items. I reread it one last time.
