Noboostnogo's turbo build v2.175
I'm redoing the headers and going with megasquirt II v3.0. Turbo will be my current one tc78 but I might upgrade exhaust cover to a 1.15 ar from my .96.
Headers are up and forward mild steel that I will get jet hot coated and getting my pops to tig weld them. More than likely turbo will be in front of water pump blowing into a water to air intercooler under the driver side battery tray. Depending on packaging issues i might go with dual 2.5" downpipes unless I can fit a single 3.5".
Trans is a built th350 with brake and PTC converter
Power goals are to put down about 700 at the back wheels

How do you guys like the MS stuff? Either of you ever use $59 code?
Thanks what Im running/ was running with the novi 2000. Im looking to either swap to the LSx pcm or something...

Re: Noboostnogo's turbo build v2.175
i would have tried 59$ on my current iroc but the po took bolt cutters and cut the harnes sin half by the fender when they put the carb on it, and the price ppl want for engine harnesses for these cars is insane, so it was cheaper for me to go megasquirt
not to mention i had already bought low-z injectors which wouldnt work with the stock ecm anywys

Re: Noboostnogo's turbo build v2.175
Sorry for the hijack.. Last question..
would I need to repin my harness for a ms setup? (7730 tpi harness)
I guess I should goto the ms site and read up. Its been awhile since Ive been into tuning. Im deff. going to have to dive back into it with the new combo.

Re: Noboostnogo's turbo build v2.175
so i finally had some time to get ont he computer and upload some pictures
this is just a random bad pic of the ms2, relay board, ms cable, iat, cts, and edelbrock fuel rails

this is my first attempt at making the headers, i will be redoing number 8 cylinder runner for some reason i dont like the way it turned out

just mocking it on a spare motor

and this is the little band saw i bought at harbor freight tool, it seems to do a great job so far

Re: Noboostnogo's turbo build v2.175
nice job man
Re: Noboostnogo's turbo build v2.175
I have the TBI adapter board, grab the manuals swap the pins around for what you need and yank the rest out. This is the way to go in a lot of ways, I really like it instead of having to deal with a DB37 connector. The only thing I will say is I'd probably do a "harness stub" if I had no intentions of ever going to a stock box again. By keeping the connectors it keeps my options way open.

Went and picked up all the tubes from the shop and they look nicely tig welded I tacked them on the flanges tacked the bullets on and im taking them back on mondayto have them finish them with the collectors and vbands on. I've started on the turbo merge and once I have the headers finished I will finish the crossover hopefully by next weekend

Re: Noboostnogo's turbo build v2.175
Crossover is tig'd. All I have left to do is mount the waste gate and fab the 3.5" dp and the hot side is done. After Xmas I will mount the a2w cooler and finish the cold side

Re: Noboostnogo's turbo build v2.175
i dont know if anyone is following this or not but heres a quick update!




I need to build a new bumper and some supports for the intercooler.
I am hoping to have this thing idling by this weekend since i ordered the fuel pressure regulator which was the last thing i needed for the efi conversion.
--I still have a bunch of stuff to do like build a ice tank which i will try to fit in the opposite side of the spare wheel compartment
--get hotside coated (any advice here?)
--wire in transbrake
--finish downpipe (waiting on parts to arrive)
--put everything back together like headlights and wiring, dashboard center console
--build new bumper support
-- and i need to brace my turbo not sure how im gonna do that yet
so what do you guys think? any feedback?

Re: Noboostnogo's turbo build v2.175
must be nice to be close to firing up your project.Im getting close to the 8th year mark with my turbo project and still have 3-4 months to go. Post up video when you fire it up. I do like how your exhaust headers are setup makes it easy to access the sparkplugs.

Re: Noboostnogo's turbo build v2.175
My headers like that allow easy plug changes for most part. Driver side i get all 4 from underneath.
Passenger side i take the downpipe pieces off and go in from up top. Headers like that clear everything well

Re: Noboostnogo's turbo build v2.175
Yeah when I built the headers I had spark plug accessibility in mind and these make it easy to get to but only from the bottom
