Turbo builds

[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.

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?

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.

What coolant is everyone using for their setups???

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)

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.

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??

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

What components did you use rebuilding it?

On 15 psi I made 650whp with my 6266. Ran it all the way up to 22 psi. Unfortunately the ring land on cylinder 2 let go. Just finished the rebuild last week and Im going to start the car up today, as I installed the engine yesterday

Only 11.7psi on e85 (Safe street tune for now). The car should be around 15psi after a dyno tune. The pump shouldn’t have an issue keeping up.

The car has -6an PTFE lines, a radium fuel rail and no inline pump. The hellcat should be able to support the 650whp goal no problem.

I have the same fuel system. How far have you pushed it power wise.
