M20 Turbo manifolds group buy manifolds shipped today..!!!

[E34DIYer]

Looking forward to installing mine too. Still need to pick a turbo - want something daily - drivable but with the potential to put 350hp to the rear wheels. Thinking either a Garrett GT3076R w/.82 A/R, or something from the Holset family (not sure which one).

Has anyone tried slapping a BorgWarner EFR turbo on one of these things?

[stanhayward]

Not an EFR but I've seen very good results with theirs Air Werkz S256SX and I'm putting one on mine and could report back. AGP Turbo makes them with smaller T3 exhaust housings as well so you're not stuck with a 1.22 a/r divided T4.

A Holset HX35 would be a good choice, it's proven to support 400+hp, it's durable and won't break the bank .
As for the EFR series, haven't seen an real world data comparing it to other turbo's. They are also physically longer by 3" to 4".

I confess to not knowing much about the Holsets. Exactly what Holset setup would I want to hit our goals - quick spool, up to 350hp to the rear wheels?

hx35 with 12cm housing. Thy make right about 350whp at 14psi on an m20 and spool fairly quickly.

[E34DIYer]

Are there other things to spec out? Inducer/exducer wheel sizes, trims, etc? Compressor housing sizes? Or do I just pick a turbine housing and I'm done?

[nomansland92]

Holset hx35's can come in many variations, I believe anywhere from 48mm-56mm inducers. The most common is the 56mm from older cummins.

Thanks. Thread jack complete.

I'm also looking at a GT3076R but with a .64 A/R housing, as I have relatively modest power goals and I'm looking for quick spool-up. Got the manifold, looks really solid with undamaged gaskets.

We may need to hook up soon if you are installing it on another iX!

Thanks, they came out real nice.

How about a group buy for Tial Wastegates and BOV..???? Anyone interested...??

[E34DIYer]

I'd definitely be interested in the wastegate. Not sure on BOV, as I want to do a recirculating setup instead of dumping to atmosphere.

[E34DIYer]

Obviously price/savings would be a big motivator as well...
