So I've being running my m30b35 swap in my car since Jan of 2015 & loving every chance I get to get the car out of the shed to enjoy it.
I've had a back & forth with what to do next between going the route of forced induction or staying N/A. Well the decision was made easier the other day coming across itb's & an adapter plate to fit my m30.
Lets call this a slow progress log of my motor, with the plans below to be known as: The iron first in a velvet glove
new head to port & flow - picking up this weekend pulled down & ready for porting
s54 50mm itb's with a customer adapter plate - arrival eta 2weeks now using s38b36 itb's
294/294 Catcam - waiting at home(I've had this for near 2yrs)
shot peened & treated rockers
To order:
PPM 48mm intake valves
Rocker locks
Dual valve springs outer springs only(catcam specifications)
Standalone ecu
PPM H beam rods & pistons 11.0:1 comp
Being in Australia usually makes e30/older bmw build a fraction harder as its a small market but in this instance I have a benefit of Rama from RHDengineering(supplier of the bolt on m20 itb kit) being based not too far from my home. When he arrives back in Australia this August my e30 will be in to get the ecu wired up & I will be seeking his wizard skill to help with runner lengths & fine tuning the itb's.
Around compression ratio's can anyone help with ideas for rod/piston combo's to see a 10.5-1 comp ratio? I weighted up the option running s38 rods to move towards a b36 but don't want to lose the drive ability &/or send myself broke going insane on parts spending(we all know budget never work with builds though)
