Yet Another 2.7i Build Question...

[Devil Inc]

Ok I currently in the middle of finishing up this project for now. I believe I have all of the parts. My problem is I'm having difficulty figuring out how exactly the crank sensor is mounted near the harmonic balancer. If someone has a pic they can post, that'd be awesome. Is there a specific bracket I need or is it already there on my ETA engine.

Parts I have:
AFM
1.1/1.3 harness out of '88
524 ECU
Toothed Balancer
Crank Sensor
"885" head
"I" intake w/ TB
Various little odds & ends

You'll need the CPS bracket.

Dont for get you need the water pump pulley and crank pulley, and you are going to want to find a #173ecu. you dont have to use the i head right away. Your stock eta has 9.0:1 Compression and if you put the i head on you will have 8.4:1 So I kept the eta head on untill I could find super eta, or custom pistons. as for the CPS it has bolt holes for it on the front passenger side of the block near the crank and yes there is a bracket that is on all i engines for it.

[Devil Inc]

Am I not able to use the 524 ECU? Also, is there a specific difference between the water pump pulleys on the ETA & "I" engines?

A little late for keeping the head on seeing as it has a crack somewhere causing it to pump air into the cooling, so I thought what a better time then now to do the swap.

[kenika65]

Yes you can use the 524ecu but it is not as updated as the 173. As for the pulleys when you put the toothed crank pulley on you will not be able to intall your eta water pump pulley or crank pulley because they are too large the i pulleys are smaller to work with the toothed pulley. And yes use the i head if your e head has to come off any ways. The only down side is it takes a couple cranks to get it started because of the compression drop and the idle is a little rough because of the piston to head differences. but other then that your going to love the i head. dont for get to buy new head bolts and torque them correctly. do you have any pics?

I want them sooooo bad but have to buy the GF a 800 e30 first so if you still have them in May ill buy em do you want to trade anything for them?

Ok so I will be able use the 524 ECU for now as I plan to eventuallly install a turbo & MS2. I test fit the harmonic balancer to see if it would clear and it appears to clear the water pump, but as for the others. I'm not sure because they are loose at the moment. As for new head bolts I aquired some "metric blues" off eBay. What would you like pics of?

[kenika65]

I all of a sudden want to own an 87 because I dont know everything about them, ha. OK so if your pulleys line up sweet. Lets see some build pics and your e30.

I am going to have to take a picture on Monday to show you but try realoem.com

[Devil Inc]

Yes a picture of this "mystery" bracket would be great. I was looking at the realoem.com diagram, and is it #12 that I'm looking for. It would be great if they kinda showed where it mounted in relationship to everything else they show.



Edit - I just found this on PelicanParts.com, not sure if it is right one but looks close.

OK here is my 86 325es with all 89325i 1.3Motronic parts on it like this CPS W/bracket.

[Devil Inc]

YES, that looks like what I need!
