I'm Souping up my car and need some suggestions...

[bimmer2288]

I've got a 325 Super-Eta and I'll be converting it over to a 325i. Here's the list of stuff I have alreay purchased to do the swap, and I'm open to additional suggestions of what to do:

'i' intake manifold
'i' throttle body
m30 AFM
K&N panel filter
'i' camshaft
Double Valvesprings
'i' ECU
MarkD chip
19lb Ford Mustang injectors
Magnaflow Exhaust
Straight Piped Catalyitic Converter
Complete Gasket Kit
Various new hoses, etc

My questions are two fold: What would you expect my gain to be with these? (Super ETA has about 125hp stock)

Since I'll be taking my head into the shop to get the cam installed, what head work, if any should I do that would cost a reasonable amount? (And when we say "head" are we referring to the part of the engine that comes off containing the valves and camshaft?)

Thanks!

If you're head is having work done, have them do the following:
- Redo valve seats
- Change out valve stem seals
- Resurface the bottom - make sure it's flat
- Check for cracks (they should do this by default)
- You COULD have them do somethin like a 3 angle valve grind, but that's usually gettin up there in price.

The SuperEta is 127 hp stock. ;)

And, normally, the budget strokers will put out 170-180hp to the crank. Depends on a lot though. I'm hoping for around 180hp out of mine, since it's rebuilt.

Do you know if the bottom end stroke is the same as a 325i?

not the same the b27 (from 325e )stroke is 81mm the b25 (from 325i) is 75mm. different crank.
