Sorry for not updating in a while. The army took over the last couple months and been really busy. Anyways I fixed the coolant leak and oil leak (Blew out my cam seals on the front head because I pressurized my intake system without moving the line that goes from intake bubble to heads…Oops). Took her for some break in pulls….I just bring her to high RPMS nice and slow and let her engine brake down to lower RPMs. I did two WOT pulls and rolled into it in 2 and 3 gear and she moves damn good for stock map and waste gate boost at 15PSI. Things that are left….Ordering some two hard pipes that go to the turbos from intake manifold (They keep blowing off at around 15PSI when pressure testing, need a new rear turbo pipe for the Dual Core…the little bracket that screws into the rear turbo cracked, new BOV(Bought a used Greddy RS to replace knock off that comes with kit and its leaking really bad), and I need to find a plug for the nipple on the back of the IM that Im not using.
Also, I posted on the other forum about my lower plenum leaking at the heads under about 18PSI of pressure when pressure testing. Very slow leak. But I unbolted everything, cleaned off surfaces and gaskets (New), and put a few more ftlbs of torque on the nuts/bolts. I asked If I should use some light gasket maker which I seen done on other platforms but the other forum said not too. But if this doesn't work I don't know what I will do to seal it up.
Also Im taking recommendations for seats to replace my driver/passenger. Looking for something that is a all around, Im a bigger guy 220LBS/6FT. This is a weekend cruiser/track car, I want something that is in the middle of the price range.
Anybody know the thread size for the nipple on the back of the intake plenum right by the throttle body….its the big one. I forgot what use to go there but I did vacuum reduction and I want to plug it instead of just having a vacuum cap on it. **So I used a 1/8 NPT Plug.....I think it wasnt the right size but was close enough to screw in and I put a shit load of thread sealant on it and it doesnt leak up to 25PSI.

Another update. Ordered 1000CC Injectors going E85, 3.75" GM Maf/Translator, hard pipes for intake bubble to turbos since they keep popping off during pressure test. Still need to get DP installed at exhaust shop. Interior is 99% complete (Wiring and All), just waiting for my new A-Pillar and floor mats from 3SX. The light of the tunnel is getting closer!

Update: Intake Plenum is leaking. Continuing to trouble shoot I have new gasket on the way for the upper/lower plenum where they mate up. if that doesn't work I'm going to go and them decked at the machine shop. It is holding right about 11-12 inches solid and when decelerating in gear it will pull 22 inches. I boost leaked check the car and the two places are still BOV (New one inbound) and plenum. It is very hard to tell where it is leaking on the plenum thought since it is so tight. So any ideas please let me know.

Make sure the plenum is sitting flat on the lower intake. I've seen where the rear lift bracket that bolts to the plenum gets bent where is prevents the plenum from sitting correctly. This is the one on the drivers side by the brake booster.

Oohnoo great advice…I already checked that thanks for the advice though! Loosened the bracket and bent it back just to make sure. My new ported and polish lower plenum is coming in tomorrow. I will take everything off clean the gaskets really good, place the new gasket that goes between upper/lower plenum torque everything down to spec, new 1000CC injectors will be going in so that includes new fuel rings, if it still leaks I will have to take it to the machine shop :(.
Also what type of gap should be running on my Coppers? I believe I did 30 but I'm thinking I need to go lower if I will be pushing low 20's PSI. BTW I took the Spyder to the gas station and had logger running, for some reason my front and rear fuel trims are way out of wack. One is -9 and the other is 9….brand new 02 housings/headers, new sensors, and doing the same thing that it was doing before the build.... Ill worry about fixing the vac leak first, but any ideas throw them out there please.
BTW just quick story. OMW to the gas station, this mini starts following me and gets on my ass. I was getting a little pissed and then he switches to left land comes to my drivers side door, gives me a huge thumbs up and big smile, so I returned the thumbs up. The car is open 02 housings, and doesn't have the bumper on so you can hear the turbos spooling/whistling a mile away…since I got a thumbs up from mini cooper, this means I'm legit now…...right ;-)
