Your in Hawaii doing this! sweet if so and I will have to come see your e30 in August when I see my Nana for her 84th.

Oh ya I noticed you didn't have the O2 sensor from the 87, you will need to because the connection is different then your 84.

eta to I

this may seem a bit redundant, but which gaskets do you use-- the I or eta when putting all the I components on an eta long block. ( intake, exhaust. ect).
where have you found the best prices for quality parts.

thanks
Owen

http://www.bavauto.com/ Is a good on-line source. But local auto parts house should have your gaskets.

http://www.e30tech.com/forum/showthread.php?t=39960 This post has the gaskets I used.

You will want i intake gaskets for your i intake, exhaust gaskets are the same, i tb gasket for i tb, when you are putting it together you will know what gasket you need.

yeah kenika i've been yanking most of this stuff from Abe's and a few bits and pieces from ABC. I'm hoping ABC gives me the LSD for dirt cheap!!! By August I should be done for sure.
I'll grab that O2 sensor when I go back to the yard and it seems I forgot the Crank Pully as well.
Question: on different thread i read that there is another connector below the fusebox that i might need. C104?
And on the 89 325i there was a sensor in the drivers side brake duct intake. Is this some sort of ambient air temp sensor?

thanks!

kenika/etasport how did you guys remove the crank pulley? any special tools required?

[kenika65]

Try rubber,plastic hammer or a piece of wood, tap it off slowly and evenly. When you put it on let the bolts press it on.

Yes there are pullers you can buy but the radiator must be removed in some cases.

It should just fall off.

i wish. the yard i'm using is finding it funny how much i've pulled of this 325. So another ? about the cam. The donor cylinder head seems to have had a cracked cam journal (or whatever you call the upper portion of the arch that covers the cam bearing) that was welded back together at some point. Cam looks good though, what do you guys think? If I pull this one I could persuad them not to charge for the head due to the damage.

[nando]

if the bearings are okay the cam should still be good. look for wear on the cam lobes -if there's a big ridge where the face of the rocker rides the cam, it's toast.

ok so i have an 89 i ....which means i have all the electronics and such plus the i exhaust...if im reading this right i could pretty much just throw a late e bottom end in my car yes? which would give me lower compression but much better low end...is that right?

[-limp-]

wooops missed something there but couldnt i just get ahold of an e crank and the super eta pistons would the i rods work out alright? at the beginning you said to use e rods

[kenika65]

In your situation you would want e crank e rods and 88 super eta pistons, or e crank i rods and custom pistons. The only reason you would want early eta flat top pistons is if you need low compression for turbo. The i rods are better because they are longer and will make you rev faster.

sorry i was a bit low on sleep more what i was asking was e crank i rods and super eta pistons does that not clear or something because you havent mentioned that combo
