I have a Z3 Shifter but it is the actual "shift linkage"....(sorry I'm British) arm that needs to be shorter now I have a Getrag 260....
Unfortunately my fab skills are not that hot to make one....

You mean shift linkage? Consider building your own shift rod. This allows custom shifter placement (front/back), and also gives you the opportunity to make a double-shear part, like UUC's. You will be glad you did. I used the shifter from a Z3 (3.0:1) If you like shifters with no slop, it's the way to go.

Thanks.....a little bit tricky with the urathane mounts and the PS pump attached but generally fine.....Gear linkage is all wrong as it was originally a 318is....I will have to research that one...

looks like the engine went in smoothly

nice job

Got the engine in the car today....Hoooray

[Dyno4mance]

Nice action shot ....any more pics? details of the build etc. what wheels and tires are you running?....what events apart from endurance racing do you do?
Engine management? dyno graphs?.....please spill the beans...thanks
HaHa......The reason I bumped the thread is because I was showing someone how to post images....sorry anyone that was offended by it

If i may make a suggestion in regards to the oil filter. Spin the housing 180 degrees. You will have to use a E30 M3 (Mahle filter model OC-25) oil filter with the adapter plate you have. I have done it both ways and on cars with headers or a turbo it makes it a lot easier to change the filter. I have also found a little lower oil temp from one race car to the other.

I thought this car looked familiar!

BMP Design sell the Supersprint header and they are available. If you wanted to go the cheaper rout Ireland sells a replica of the Supersprint but the fitment is a get what you pay for scenario not bad but could have some primary alignment issues.

The last race was a 12 hour enduro and i had absolutely zero oiling issues. there are no locating posts but those are basically just to index it.

It is running a Supersprint header.

Thanks....I will try that
Are supersprint headers available? or are they unobtainium?
I was looking at the bav auto headers on mine unless anyone can convince me otherwise
Thanks for your responses

Is there anything special about the spacing on the alternator pulley, or will a generic one-groove pulley work? I think I nuked my alternator bearings at the track last Saturday...

Nice work!

Mine is an IE aluminum alternator pulley that underdrives the alternator....It looks like it lines up perfectly
although it is yet untried.....maybe your belt was too tight?

I have seen that done else where on this forum...
Is there not locating lugs on the backside of the filter block
How does it locate if you flip it 180....will it not disrupt correct flow through the filter?
By the way, what headers are they?
