M30 turbo build

[Good & Tight]

Otis or anyone else,
I wanted to get your input on the setup Im looking to build. Im shooting for 400+ hp will the HX40 be my best bet? How about housing size will 16cm make me spool late? Ill be running stock b34 botto ith stock b34 head. Will 42lb injectors get me to my goal? Anyone know of where I can pick up a HX40 in need of a rebuild? I got a quote of $850 for one already rebuilt.

HX40 is a perfect match for what your doing, 16cm is what I have in T4. My engine is a B34 also.
I would suggest 55# for some head room, what engine management are going to use?

Otis,

I was planning on just bolting them to my spare head (it's busted beyond repair and I got it for $25)...will that be OK??

That's how I do it also, bolted to the head but still weld the piece in and leave it in.
Reason for this is after a few heat cycles running on the car they will pull together, I experienced this when I first went to pull mani. Not that it wouldn't come off but I had to pry it off.

Are you going to do a header, or adapter?

[Good & Tight]

When using the stahl head flanges weld a piece in between the flanges to keep them from moving. Like this

I'll write up the details of mine once it is done. Tuning megasquirt NA now, but have all the parts:

M30B35, rebuilt head 50k ago + bearings
16cm/8blade HX400
Ebay intercooler and piping
tial 38mm wastegate
Ebay BOV
Stahl flanges for M30 head (and a spare head to mockup my manifold on)
Coolingmist Methanol injection kit
14point7 NAW wideband
NGK plugs 3 ranges colder
JEGs 45kv coils for wasted spark (still need GM baseplate)
GM IAT
MS2 v3.57 (will be running custom modified 3.0.3t code with fuzzy logic traction control, and launch control via clutch switch)
M60 throttle body for flipped manifold
Exedy 6 puck clutch kit on 533i lightened flywheel

Will be going groovmatic O-ringed + oversize elring klinger headgasket+ APRs + 284 regrind for "stage 2"


once the low boost build is tuned. If I ever need more power, I'll upgrade compressor to 6blade.

weak. my 318 could take that..... :D
should be fun!
what plugs did you get? I grabbed 2 colder for my nitrous build, but i haven't even started the motor up yet. just got the tranny mated to it last night after waiting 3 months for a flywheel

im interested do a writeup i wanna turbo charge mine after i do the m30 swap

31# injectors might be to small, also since your going to run MS you can eliminate the TPS sensors and run on MAP only.
For turbo selection I would look into a Holset. With your budget of $2500 and doing all the fab work you can make a great turbo setup.
Upgrade your clutch also, the engine will make more torque than HP.

I'd take one for sure

My power goal is to make around 400bhp which will require me to run around 15-16 psig at 44lb/min of corrected air flow.

As for the components, I have not gotten many of them yet because I am still in the collection of components phase but I do have so far:

MS1 v3.0 extra 029y4 firmware
6 pin TPS
oil pressure sender and gauge
31 lb injectors
adjustable fuel pressure regulator

My budget will be around 2500 as I am fabricating everything myself which keeps costs suprisingly low.

It sounds like there is some interest in me doing this build thread so I guess I just go for it.

turbo build writeup go! always wanted to do one myself, the swap was step one, now im slowly saving up. whats your hp goal? what parts are you planning on using?
