I just picked up a 2.1 head and manifold:

I also have an 85 900 exhaust cam.

I have read that to take full advantage of the 85 exhaust cam, you need to run a 9000 intake cam.

Given that the same head is used on the early 9000 2.3L Turbo and non-turbo motors, does it have the same cams?

Nope. NA means Naturally Aspirated. You need an intake cam from a Naturally Aspirated car. Not a turbo.

The head is off a N/A.



Were you talking about the cams?


EDIT: the cam is an 85 cam. I'm a moron.


:roll:

I was trying to say that you need an intake cam from a NA car.

Welcome to the club.

Didn't the later (like 89+) 9k's use the same cam as the n/a anyway?

That's what I'm trying to figure out!

Am Baron, am serious search fanatic. No joke guys, baron knows his stuff.

Yep, all 9k cams 89+ are the same as the n/a.

 

[Palmer1980]

Nice.


Thanks for the info.

That looks like it's out of a bentley. I have one sitting next to me right now. I guess I should have cracked it open.

;oops:


It's going to be a fun winter, ser.


Don't be jellus.

That picture shows specs for B202 engines only.

B234 9000 engines--that is, with the same head as the B212--have different cams than the B212.

Ah, good eye. Weird, though Widde's data conflicts with that shot from what I assume is a factory manual - it doesn't list the old n/a cam as going on a plain b202 (not "i") for a year or whatever it was.

Good to know those performance grinds are listed there

I have some photocopies of both B2x2 and B2x4 cam data from factory manuals; couldn't find them last night but will scan if they turn them up...
