Turbo builds

[Nicholas1996]

Looking for people to share their builds. Mine is as such
6266 precision
spa manifold
tial bov and wastegate
mac 4 port
fsr intake manifold
aem infinity


lets all exchange some info on turboed e46 m3s

[Hallerhan]

Looking to start my build this summer!

did you install everything yourself or pay a shop to? I’m trying to get any idea of what hurdles I have to look forward to haha

BW 64.5/67
SPA exhaust manifold
tial wastegate and synapse bov
flex fuel
2 walbro 485 pumps
ID1000 injectors
radium engineering surge tank

Hey. Yeah installed all myself. Please message me if you have questions.

I really want to run a BW turbo. I have no one to weld the wastegate housing though.

The BW is super laggy compared to the 6266 I started with. If I had originally built the engine, I would have stuck with the 6266 or gone to a 6870 with their fast spool. Now I'm building it and I wish I hadn't have gone with the BW. I may try max it out and see how much it makes though. It was running 25 psi the last time I had it out.

Curious to see how this turns out

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

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.

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.

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

What components did you use rebuilding it?

JE pistons molnar rods stock crank and block

[Mspir3d]

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.
