Turbo builds

[Nicholas1996]

That's very similar to engine I'm building with the exception of the pistons. I'm curious to see how well the molnar rods hold up though. The stock rods were holding over 800 whp but it was probably only a matter of time for them.

what pistons did you go with

[Mspir3d]

The shop recommended wiseco pistons. Some of their past turbo builds with the JE pistons suffered from false knock. Strangely they are owned by the same parent company from what I've read.

Are you going to run an upgraded oil cooler??

[Mspir3d]

I'm not planning on it. I haven't had problems with oil temps yet. I've run 10 psi on the road course during the summer and drag raced at full power in 95 degree heat. The temps did drop after I vented the hood.

I am currently in the process of installing a custom kit purchased back in December.

gt35 .70
technica Intake/exhaust manifold, intake pipes and ic
1400cc injectors
rolling antilag
flex fuel
walbro 540 intank + Bosh secondary
hexapump oil pump
proefi 120
proefi ignition coil packs
radium fuel rail + variable fpr
can display logger
synapse bov
Full 3.5 exhaust with Tial wastegate dump
radium catch can
+ some other tidbits. No power numbers or drive ability as it’s yet to be fully installed and tested.

Interested in seeing how the EFI 120 works out. I’m still deciding whether to go with the pro efi or the AEM infinity (and convert to manual)

What coolant is everyone using for their setups???

[TylerBrown]

Roughly 60% distilled water, 40% bmw coolant and a bottle of water wetter. There’s back and forth with water wetter but so far it’s been fine for me. I live in SoCal so the hottest day is about 90 with high humidity.

For you guys running the SPA manifold... What is your secret for getting that manifold installed?

Currently I've had to unbolt and remove the oil drain line from the valve cover to the oil pan because it doesn't fit and it definitely won't fit after the manifold is installed...

And then second I installed the longer exhaust studs into the cylinder heads that have the eTorx heads...


They're all threaded and evenly and fully seated.. I cannot get this manifold on I can't even see which one is not going over but it feels like one or two of the studs are not going through one of the holes evenly..


Got any tips for how you got yours installed?

[Mspir3d]

I took a drill and slightly enlarged the holes for the studs on the manifold to start. Just a little enlarging was enough to get it on the studs. My head has the longer e36 m3 head studs. Then I had to push the manifold partially onto the studs and put the nuts on. The nuts wouldn't fit on the studs if the manifold was flush with the head...lastly I took an 11 mm wrench and ground down the sides of it to get around the nuts towards the back of the cylinder head. Installing it on your back under the car is a bit of a nightmare.

okay thank you very much that confirms what I thought I would have had to do with the stud holes on the manifold. But I'm also curious about the oil line that comes from the valve cover and goes down to the oil pan did you just get rid of that line completely?

If anyone would be interested I’m selling my turbo kit hpf kit pro Efi ecu Saad racing fuel lines full flex fuel close to 900 on a built motor with a 6766

The oil line goes from the side of the valve cover down into the oil pan.

Yes sir I understand that. the SPA manifold would not fit onto the head with that line in place. I had to unbolt the line from the valve cover to get the manifold on the head but now obviously the line does not fit around the manifold while bolted to the head.

are you saying that you had 0 issues with that line and didnt have to move it at all and your SPA manifold bolted to your cylinder head fine with that line in place? If so then i guess i'm headed back to the drawing board lol

Ok I see what you're asking. I have a maximum psi kit that came with everything. There is a AN fitting and a long braided stainless steel line that I looped around the back of the head away from the manifold.

wonderful looks like i have some more work to do then to adapt the valve cover line to an AN Steel braided setup but it answers my questions.

thanks for the help and info!

ill get to work on enlarging the SPA manifold holes as well for better fitment
