You will get more than 380

[ninjaman111]

Are you having 4b do all the work? Im going to install a AA stage 1 soon and I want a shop to do all the final touch ups but I'm in santa cruz and idk if their are any local shops that do that here and I've heard good things about 4b. can't wait to see this one complete!

[///dean]

Cool!

Guess u had time for a build thread after all .

Looking fwd to dyno updates and pics of the final product as well.

[IR M5]

Subscribed. I just put a deposit down on a TT Stage 2 kit. Excited to see the outcome of this product!

Edit- I also have also decided to go with a Southbend Stage 3

I agree, I was around 390-411 on Mike Radowski's old Mustang Dyno with a damaged impeller at low boost. The upgrades are similar to mine but I do have a 3" turbo back exhaust built by Mike. Never went back to the rollers with the new turbo but it screams, your'e gonna have fun.

Yes, 4B is handling the whole install.

When is it expected to be done? And what kind of gauges/setup are you planning on going with?

Great choice on the boost controller. Best "addition" I've bought.

Found more pics



Bent AC line done


Another underneath shot


Boost proof the ICV barb


IC piping test fit


Doesn't look like the turbo blanket will fit due to the spacing limitations

[IR M5]

Did you happen to do a compression/leak down test beforehand?

[rodw]

Did you happen to do a compression/leak down test beforehand?

Nope, I had no reason to do one since it was running great.

[Butters Stoch]

Inline 6ers will run very well with weak cylinders.
Hope it works out well.

[rodw]

M50 installed



Still lots more to do

[IR M5]

Are you planning on keeping the cats? A full 3" exhaust system would be pretty sweet..

[Sniz]

looks good!

Yes, don't want to deal with the catless stink. Going with stock midpipe with Dinan exhaust.

[///dean]

Putting in my guesstimate of 405whp on our crappy CA 91.

[BigM62]

Yes, 4B is handling the whole install.

Hear good things about 4B.

[stanksbeamen]

There's no way at all to fit the turbo blanket on there? I have a TT M3 as well and I'd really like to put something on it next time I have it off, engine bay gets extremely hot esp being in hot summers CA has. My first exhaust looks exactly like you have yours, when I went stage 2 I got another down pipe from NickG and had a 3in built. Good build, engine bay looks clean!

[stupenduzzman]

David at 4B is the man! He built my motor last year and it's been running well and he's been extremely helpful afterwards.

From the looks of it, spacing is extremely tight in that area. Is your exhaust manifold and turbo housing ceramic coated?

Some more progress...

Radiator done




Bumper back


Charge pipe installed


My untrained eye is guessing the coolant/oil feed routing will need to be adjusted when the oil pan is tapped and connected to the turbo oil drain

Little trim to fit


Hope it's not too low

[auaq]

Why do I always read the title as 996TT build?

[NickG]

That charge pipe is sitting much too low. The 2" end of the 90 silicone elbow connected to the compressor outlet needs to be trimmed slightly to raise the pipe up. The pipe should hug the subframe, and sit in the crest between the subframe and ball joint.
