Ok guys I am planning to use my truck mani's for my turbo build but one has the air pipe on it.

Was wondering if I can just make a block off for it and run it that way. PLease let me know guys, planning to start building tomorrow.

should just unbolt right at the manifold. then make a small blockoff plate and be done,im using the same manifolds you have. wont cause any problems that i can see.

Ok thanks for the input, just wanted to make sure.

Also Were can I get the 3 bolt flange that is od shaped?? I know I can search but have been searching the last 3 days on all kinds of crap.

the collector flange? you could maybe order a y-pipe from somehwhere like rock auto and then hack it up to meet your needs or look in the wreckers on the late model trucks, thats what im plannin to do.

I think Motovative makes the flange you speak of, also try mandrelbends.com, theres another sponsor that sells em too but the name escapes me at the moment

there are 2 different styles. one with the ring and one with a lead gasket.try to get the ones with the ring. try a muffler shop or find a dude who put long tubes on and get his old y pipe. i got mine from modular turbo. rob just had some from a header swap. i have a donut style if you need it

I ordered some from motivative yesterday.

Now wondering what size wastegate I should run?

Looking at the tial 38mm but see a fair amount of guys running 44 to 50mm. My hp goals right no are around 500 with fairly low boost on a mp t76 Q trim. but would like to up it late on to around 600 or so.

Will I be able to run a 38mm or do i need bigger?

I had a buddy make 655rwhp on a 38mm wastegate, so I would assume you'd be fine on that. That's the size I'll be running.

You size your WG to the ammount of HP you want to push out the tailpipe, not how much you want to push into the engine.

Ok thanks for the info guys, any of you guys know the size of the tial 38mm inlet flange. Need to know for the specs of the pipe running from my manifold.

Thanks in advance.

i use a 38mm with my mpt 76. it seems to control boost pretty well.
