12a Turbo update

My new setup is almost done I had my old setup running for a month or two before I decided to tear apart and change basically everything.

Old Setup: Stock 12a, Nikki carb, ported j-spec 12aT manifold, TII turbo, ported wastegate, 2.5" stainless exhaust, no intercooler, tyfoon bov

New Setup: 12a is studded and street ported, Rotaryshack apex seals, TII turbo spaced out 1", ported wastegate, custom intake manifold made from 1.5" tube, weber 48dco-sp, two TII intercooler cores welded together, tyfoon bov, 2.5" stainless exhaust

I'll put up a bunch of pics as soon as I can. And unless something really bad happens, the car will be at the rotary revolution

Just another update. Car will NOT be at the Rotary Revolution. Tried to start it, and there was a huge coolant leak. Turns out one of the rear coolant seals isn't seated right and the rear rotor housing is just filling with coolant, ****. Engine has to come back apart and replace that seal.

They are a better material, and have a much bigger corner piece, still 2 piece.

I sold the nikki, didn't like how it ran at all and didn't want to mess with it.

Thats a real bummer.

That car is going to be FAST. I bet your making at least 300 hp at the flywheel.

It's a manual boost controller, just a bleeder valve from home depot. I'll probably just plug the wastegate lines now.

Yeah, it really sucks that I can't take it to the rotary revolution now. It'll probably be another 2 weeks before I start driving it now.

Yeah, it'll be around 300, cause that's what the TII turbo's max out at.
