Oh The Fun Of A 327i!!!!

[Devil Inc]

:twisted: Man I have to say this is probably the most amazing improvement possible to a lowly ETA motor. All I can say is WOW!!! :D :D I haven't got all the minor wiring finished yet, so I haven't bounced it off the r3vlimiter yet.

The specs are: '87 325es bottom end - not sure of actual mileage because it already had an "is" cluster in it w/ broken odometer gears, '88 I harness, "I" top end, "I" AFM, "I" toothed crank pulley, and such. Also, I used "metric blues" to hod down the head, I torqued them to 85 ft-lbs.

Contrary to popular beliefs the "e" bottom & pistons with the "i" top end makes the car very much movable. :) Lets see I can pull from 70-100 in a matter of seconds not minutes, which is what it took before swap.

I would've swapped pistons, but I plan on going with some boost in the near future. So far the swap will hold me over until that day.


P.S. - Oh also, I like both BavAuto & Pelican, I have purchased head gaskets from both places and the one I got from Pelican. Which is a Goetze (sp?) is by far a better gasket. It is sturdier looking/feeling, just looks like a better gasket.

so you used the pistons of the eta and put the "i" head on it? i didnt think it was possible because the pistons where not able to work with the "i" head.

yeah ditto...I ran into this prob aswell to..

please eXXXplaaaaaaaaaaaaaain.

MY CAR IS A 327I BUT IT HAS 88 SETA PISTONS oops didnt mean to shout

i was under the impression that the compression would be too low na on this set up?

More mythical bullshit.

Yes, the compression is lower than ideal. Yes, the shape of the piston is not ideal...but it WILl work, even N/A, and can be a beast under boost.

My big question is emissions, if it will pass Kalifornia smog tests.

i had a seta bottom end and i top end on the car jam currently owns. it definitely moved

[Devil Inc]

Yeah it works. I'm not sure about emissons, as we don't currently have any required testing here in Indiana. Currently I don't have the O2 sensor hooked up because the '88 harness is a 4-wire & the original one is a 3-wire. But as I'm looking to boost, I'm going to be getting a wideband. The car feels like it lots a little bit of torque in the bottom end, but the response in the mid to top is amazing.

Glad to hear that you have got the 2.7i running. Is there any way you can make a video of starting it in the morning(cold start) I'm curious how easy it is to start with the i head. And a sound clip of the idle. Thanks Also do you have any pictures of your e30?

[Devil Inc]

I do have a minidv camcorder but i'll have to use my neighbor's pc to put it on the computer. Of the few computers I do own that work, none of them have firewire. I assure you that it starts rather easily and well. I do recall the other morning, I had frost on my windows and it cranked about 5-6 times before it started. But other than that time it only takes 2-3 cranks. I'll try to shoot some pics this weekend.
