Modifications and tuning
1982 E21 323i (July 1982)
M20 “eta” block and 81mm crank throw
10.5:1 CR (produces 190+ on a cold compression test even with Intake Valve closing as 72 deg ABDC!)
Forged light weight 330g pistons (vs 397g 325i, 420g eta) with circumferal squish design and slipper skirt design with low friction coating
Schrick 284 duration cam with low friction coating
Large U-port cylinder head casting (“885) with 3 angle valve seats fully machined ports and chambers
Dual valve springs
135mm length con rods (longer rod/ratio than usual “conversions”-ensures low friction and favourable high rpm loading) with greater small end lubrication
Hayward and Scott fabricated stainless steel exhaust system – (180 mbar back pressure measured from downpipes-eg. For comparison E36 3.0 M3 has back pressure of 240 mbar at peak power measured at catalyst cone) 54 mm OD twin pipes and low restriction silencers-tubular tuned length primary pipes (40-45 cm).Twin pipe system ensures lowspeed torque
Twin entry duct air box, K and N panel filter
Larger diameter K jetronic updraft air mass meter/fuel distributor assembly to suit 30 % greater intake air flow
68mm big bore throttle body
“low” thermostat- lower bore temperatures allow more ignition advance without running into knock
Oil cooler sourced from BMW 850i
11 blade viscous fan as opposed to 9 blade
efficiently cored aluminium radiator
14 blade impeller cooling pump (vs 7 for stock m20 323i)

Alpina front apron with brake cooling ducts
Remote central locking
Leather E21 pergament interior
Leather BMW sports steering wheel and gear knob
Chrome door handles
Chromed B pillars a la E12
Late ellipsoid head lights a la E30
Especially calibrated and built ignition distributor –more ignition advance at low engine speeds with no knock –27 deg at 1900 rpm
Higher capacity vacuum capsule for high part load ignition advance (up to 46 degs)
History
The first Car I ever bought against my late fathers wishes in 1990!We've been through life and death together-seen women come and go.Gradually as I grew up the car evolved with me and we've become the best of friends! Was originally an average car, slightly rusty and an oil burning 2.3 in Kaschmir Gold. Gradually I tracked down almost every option I could find, including recaro seats which I retrimmed in leather, My own brew of 2.7 litre engine,LSD, Alpina wheels etc. Has been covered in an extensive article in Total BMW magazine in Novemeber of 2002. |
