Ive been thinking of going with M42 stroker turbo instead, and was wondering if anyone could help me with the compression ratio of a setup ive been thinking of.

Standard M42 block
M47d20 crankshaft 88mm
Stock M42B18 pistons
135 mm M50b25 conrods NV

Any help appreciated greatly!

Swaps, Turbos, Buildups / M42 semi race engine - Possible turbo build

Hello everyone!

I have a BMW E21 race car, which has a 290 hp S14 in it.
Now this engine is going out for a full rebuild. As you guys probably know s14 part prices are insane these days, so i expect the wont be ready for quite a bit.

So i decided to build a budget m42 to use in the meantime.

I have
a complete m42b18 e36 engine
M47d20 88mm crankshaft
S50B32 throttle bodies
DTA s60 ecu

From what ive been reading these parts are useable to make a fun engine.

I guess my questions are these:

What rods/pistons do i use?
Headwork?
What will i need to do to get about 200 flywheel hp?

Thanks for the help!

Tommy
