That's pretty damn good #'s to the wheels. Check your accel enrichments, they can cause missfires. Also did you modify the engine mounts?
Car looks super clean..!!

Alright, I'll check it out. I'm also thinking it may be noise in the cps circuit or possibly normal tune up stuff. I don't really know the condition of my coil or distrib. Here is a quick pic of my graph, I'm wondering where I should be making peak power with the 290 cam and no misfire.



And no, I didn't modify the mounts at all

Well, time to update this. I cleared up the misfire that was shown in the last post and I had just been driving and autocrossing the car, until about 3 months ago. During a spirited drive the car developed I sharp misfire. A compression test showed 20 psi on cyl 5 & 6.

I pulled the head, and found this




So, one thing led to another and since there were a few things I wanted to address on the e30 I decided to pull the motor/trans again. Then I found this:



That's what I get for driving hard with poly trans mounts and rubber motor mounts I suppose. Needless to say, this put the e30 on the back burner, and that's where its been for a few months



Now, that my e34 is pretty much done and with the weather getting nice, I got back to work on the e30. The head got machined, and I'm going to freshen it up while its apart. Since the m90/m30 has such tight valve to piston clearance as it is, I'm going to dry build the motor with a stock thickness headgasket to check for valve clearance.



Looking forward to getting it back on the road! Still need to get the transmission welded up, do the motor mounts, wheel bearings and THR bushings so updates coming soon I hope

Also picked up this seat from a friend, hoping to get another seat and rollbar to go with it soon. Stock sports seats just aren't cutting it

Sucks about the hg! But, looks like you are making quick recovery! Nice job!

I haven't touched my e30 in weeks :/

updates?

What a coincidence that this thread was bumped yesterday...

[Jb325is]

Yep.. I've just gotten serious about working on the car again, finally! I have ordered some maintenance parts and Lorin did a great job porting my head for the throttle bodies/adapters. Thanks again







Next step is modifying the thermostat housing to clear the tps.

[325ix]

That is a huge amount of porting done! It looks amazing.

Sub'd as i'm doing the same swap with ITB's on my E30.
Keep the updates comming:p

[csermonet47]

Glad to see you wrenching on the E30 again! Porting looks great. Hopefully we can all meet up one of these days.
