RE: Let's do the engine!

Rms 6-rib 6"crank, lucky enough to find one...

Installed! With new AC Belt

New green top 42lb bosch injectors


New porsche 3.5" maf

And the tune

RE: Let's do the engine!

Boost leak tester, found boost leaks around my whole intake... After 3psi, leaks were pronounced...

Soooo... Need to reseal intake to hold some boost


Main leak was ofcourse the icv/pcv coupler, so sanding away to jb weld it permanently



Make sure it's upside down when curing so the epoxy can evenly seal around the base. Jb weld is very fluid...


O-ring for FPR

RE: Let's do the engine!

Just some sensors while I'm in


Make sure T-clamps are used where possible, my old screw clamps couldn't hold past 6psi. After retest, intake can now hold 15psi solid

Old bremi's

New bosch

Boost!!!

Any problems with belt slip? I was gonna run a grip coated 2.87 pulley hoping for 12 psi.

Boost gauge!!


About 13psi at redline reliably with my setup, 6" crank and 3.25" pulley.

such a nice build :)

[GnarShark]

never thought about dying carpet :popcorn:

13psi from a 3.25 pulley! that's pretty damn good.
How much did the TRM tune run you? Did you dyno it or did they just send you a base tune?

My bracket is designed to utilize the stock auxiliary belt so I'll have to stick with the 5.25.

RE: Let's do the engine!

sad times guys :(
headgasket blew!!
driving in traffic and didn't notice my temp gauge on red!, found aux fan
resistor just went out. had no cooling to my radiator, had the heater on blast and pulled over... but too late the damage was done. burning coolant, now I have a steam engine lol

Car now just sitting here

Removing engine, decided to do a full overhaul.

That sucks. I recommend you send your head to APM Custom Engines in Morgan hill. Felix did my head for $325. Recut valves with a 3d cutter, valve seals and resurfacing.

Glad I did a resistor delete ^.^

I'm running 15 psi on a stock headgasket without orings and no problems so far. I'm on e85 though.

Epic build. Sorry for the steam engine.

[AdOz]

That boost gauge is awesome!
Great build

Sucks about the explosion

Let's get a LIFT!!!

this thing weighs a TON!!! needed an engine lift to take it off of U-Haul



Jacking one side just to remove shipping bracket





Drilled 12 holes 6" deep, then torqued every nut

Test Lift on Alpina e38

[2mAn]

Is that as high as it will lift the car?
