e30 m30 Turbo Build

[e30 335i]

Ive had the m30b34 in the e30 for about 5 years now
Its had a hard time and started using oil so its time to come out for a rebuild

Plan for engine:
Get crank ground
new bearings for bottom end
bore and hone block
reuse stock rods
low comp forged pistons
block decked
fully balanced assembly
head skimmed
cam regrind
heavy duty valve springs
billet rockers
rocker stoppers
mls gasket
arp head studs
garrett gtx35r
top mount manifold
custom front facing plenum
80mm universal throttle body

Motor is out of car and ready pulled apart
Will post some pics soon as its getting some mtech1 goodies as well...:)

Couple of questions guys

Wasted or sequential spark with msd coil packs?
8.0:1 or 8.5:1 comp on the forgies?

Cheers

Your ECU choice will answer the first Q.
Your boost/HP/fuel will answer the second.

[Boosted E30]

I wouldn't go lower then 8.5:1, off boost driveability will suffer. I don't know the stock CR of the M30 but depending on you HP goals and what fuel your using you could go higher then 8.5:1.

Going with a Haltech Platinum Sport 2000 ECU
Not sure on how much boost yet
Hoping for minimum of 400whp on e85 fuel

Being that its an m30 I wouldnt say it will suffer. Stock is 8.0 but if it were me id go 9.

[Boosted E30]

Like I said I wasn't sure of the CR of the m30, Its all good though. Since he's using e85 id definitely go 9:1 and crank the boost up. Should make some insane torque.
