Turbo m52

[Blackangusinc]

So I know this is over a year old but...

1. What kind of compression numbers are you running? With 13+psi you surely aren't stock 10.5:1... right?

2. Is that the TU motor or the iron block?

3. Internal mods? Pistons, cooling? Stock displacement?

Beautiful dyno graph!

Bump. Any updates?

GT4088 on M52 is something I'd like to try.

Thanks dude!!!

Still draining turbo oil to the timing cover, yes. No issues and seems to work better on these motors than draining to the pan. With the old drain to the pan id loose about a quart of oil when i unhooked the drain...

Haha yeah wiring blows! And im using this thing for power gnd distribution:

Pretty nice product. I like the screw terminals more than the push on spade ones. I think theyre more secure. Im running power from the ignition to it and a big 4 gauge wire from the gnd side to the engine block. Seems to be working quite well.

And i ended up ditching the oil manifold. It looks like its leaking for some reason. I think the mating face for the oil pressure sender wasnt flat / smooth enough. oh well, the cluster light wasnt working anyway... Ideal solution would be to run a sensor with the ecu and have it turn the car off or something if pressure gets low... Im going to try to get it working again but spewing oil on the dyno isnt fun.

Im going to try to get my AEM "dyno math" set up tonight and knock sensing tomoro. Basically takes a bunch of calculations and figures out how fast your accelerating and gives you a dyno like plot in the log software. Hopefully have knock all sorted and id like to see how the dyno math in AEM compares to the real deal. Also got manual boost control hooked up for easy changes on the dyno as it takes too many runs to dial in a boost pressure via the EBC.

Your car is great.

I like your oil manifold setup I think I'll steal your idea for my m42.
Are you still using the oil drain into the timing cover?

I feel your pain with that wiring

I just chopped of my motronic connector to attach it VEMS
What a pain, are you using any sort of fuse block before your computer?

Cant wait to see what kind of power your car puts down.
Spinning in 3rd, I cant imagine what thats like.

Well im running NonVanos cams and what not so i dont have to deal with it.

If i were you id get someone to chip tune the stock ecu. (TRM or Nick G from technique tuning) Standalone ecu is a TON of work and its really a difficult thing to get working well. Unless you pay someone to get it running (like i did). I didnt have very good luck with megasquirt but thats not to say it dosnt work. I like my AEM so far but like i said, lot of work and i paid Maximum Psi to get it running for me.

Can't believe I haven't seen this thread before! I'm planning to run one of Jon's manifolds with a GT30R on the M52. Debating on going with the multitune using the stock DME or megasquirt or something else...any suggestions? What are you doing about VANOS?

Saturday i decided i was going to rewire my cam/crank stuff. I wanted to add a connector to the crank so i could disconnect it and i wanted to run it under the intake like stock...

I opened up the glove box to pull the adapter harness and basically got fed up with unhooking all kinds of small connectors / BS wiring. I decided to ditch the adapter harness and hardwire in AEM to the engine harness. Yay another "small" task turns into a major one!





Long day yesterday getting it sorted out. Pics when i have the balls to shrink all the tubing (once i figure out if ill EVER want to add anything and im certain everything works lol)

Oh and should be on the dyno this weekend or next!

If anything the tires are low. I haven filled them in a while and it's gotten colder. It's probably the temperature but the car feels good haha.

And thanks guys!!

[tabasco]

I want this in my wagon....


ok...and in my E30!

[Schnitzer318is]

It spins the tires in 3rd gear at like 13psi. A few weeks ago it wouldnt spin em in 3rd at 17psi with the holset... Maybe its cause its getting colder, who knows.

I think it has a good amount more power left in the timing maps which im afraid to step up on the street. I cant wait to see what it puts down

Did you add more air to your tires? My turbo m42 was getting "bad" mileage (23mpg) so I checked the tires. All for corners were 10lbs low. After refilling car felt quicker again and mpg back up to 27 (if I don't get retarded with the loud pedal). Also will easily brake tires loose again.

In the same boat as you on waiting for a dyno and proper tuning... anxious to see numbers. Wanted 200rwhp at project beginning, but I think it will actually put down more after driving it for awhile.

Good luck on your dyno.

K now i think i new some new tires. Dialed the boost to 16-17 psi and it steps out pretty hard in 3rd gear with a passenger. It spins the tires in 3rd gear at like 13psi. A few weeks ago it wouldnt spin em in 3rd at 17psi with the holset... Maybe its cause its getting colder, who knows.

Ah, looking good mang. I sure would like a 666 manifold, but I wonder if that obx ebay mani would work for now...

Also, where is your oil feed off of?

Jon (666fab) and i talked about trying to fit a e36 top mount in an e30. The turbo would probably be in the headlights and you probably wouldnt have any hood clearance at all. (OBX copied Jons e36 manifold)

Oil feed is off of the pressure sender in the oil filter housing. Heres a pic of the "test fit" of the little oil manifold i made on the old NV motor.



Now its attached with wiggens clamps but you get the idea. Notice the OEM pressure sender is on the front of my manifold.

looks slow j/k, nice e30!

Yeah, im bored already. I need to man up and turn up the boost!!! (thanks!)

And turns out my boost target is 217kpa... makes sence why i made that much boost haha.



Thanks dude!!! Jon Volk is the man!
