    Following this closely. I have an 88 SETA and I keep second guessing myself on whether or not I should go 2.8/9 or just slap the 885 head with a 272 cam on the bottom and be done with it. Not looking to piss the fiance off and just need a little extra oomph something to keep up with my buddies 325i in the mountains.
    ATL_E30 the e30zone.net link I posted above provides SETA conversion instructions - you're lucky! just need the double valve springs and cam along with the rest of I bits.

    This is probably the easiest route to go as few parts are needed. The parts listed here are the ONLY parts needed.

    325i cam 325i fuel injectors, rail, and pressure regulator 325i valve springs 325i intake manifold 325i throttle body with throttle position sensor 325i idle control valve 325i air flow meter 325i intake boot 325i ECU

    The "super eta" already has the proper head with all 7 oil journals, it just needs the stiff valve springs to prevent horrible valve float and/or valvetrain damage, and the cam. It also already has the i wiring harness and most of the same electrical components, as well as the dual exhaust. You will also need the various gaskets and head bolts associated with a normal rebuild. The "super eta" has a 6k tachometer, which will read fine until it nears 6k which it will just stop until the revs return to under 6k.

        Parts car M20 IX motor and tranny have been pulled. Note to self
        - scissor lifts make it difficult to pull engine and tranny together.
        - pulling the motor and subframe from below is great, but disconnect the steering column u-joints and the clutch slave cylinder before trying to move the motor.

        Head still looks new after rebuild - gonna be trading it for a ported and polished head.

        Since I only have one lift I will need to finish dismantling the parts car before putting Cosmo under the knife. In the meantime I'll dismantle the motor and get all the bits going into the stroker cleaned up.

        will add pics in a bit.
