[urq] urq Digest, Vol 43, Issue 31 (MC Head on WX engine question)

Wed May 30 13:06:32 EDT 2007

I am running 034EFI IIc
WR bored to 83 mm; stroker crank 92 mm = 2.5 litre
Eagle rods
AAN valvecover with coil-on-plugs
AAN flatbelt for generator and WR hydraulic pump
Garrett GT35R82 turbo. Custom EM and 3B IM cut before the bend for throttle 
so throttle is relocated.
IC just in front of new 034EFI radiator with new fans

Problems with the trigger-wheel

To-morrow ought to receive carbon sports hood from Roman (hi Roman)
