Quick question - are you running a distributor cap?

This is where the least clearance to the radiator is on my swap - with the e28 radiator I have much more room to the pulley than you have, even with the AC pulley still fitted, and the distributor cap is still quite tight at the top of the radiator.

If you're going multi-coil / wasted spark, then it won't matter as you'll blank off the timing cover, but if not then I doubt your distributor cap is going to clear that radiator looking at the photos.

Z3M radiator clearance...now it fits!

Problem solved by removing AC pulley (car never had functioning AC anyway) from combination AC/PS pulley.

Added almost exactly 3/4 of an inch clearance between pulley and radiator. Radiator sits on stock mounts and hold-down. No further mods required, nearly an inch of clearance, overall.

Held crank with 36mm socket and long extension, removed 8x 13mm bolts, removed pulley. Used my flush cut saw with metal cutting blade (WD40 to cool). Took 5 minutes and was very clean. Polished rough edge with emery cloth and gave it a shot of black paint. Done.

Looks factory and gave me the clearance I needed to use the larger radiator.

[CharMick]

One other thought on clearance....remove the entire AC/PS pulley (see #2 in copy of picture from REALOEM) from the crank, leaving just the WP/Alternator pulley. Weld a pulley to the alternator pulley (see picture....there was a company making something called an Add-a-pulley for offroad welders) to drive the PS...seems do-able. The company does not make them anymore but he describes a way of doing it yourself. Link:

Here are the pictures of the intake height from front and side.

[CharMick]

Firewall massaged. I may have gone a bit overboard but I did not want to have to pull/reinstall again. About 1mm clearance between the AC pulley and the Z3M radiator. Considering splitting the pulley but I am concerned about unbalancing the crank.
EDIT: After removing the plastic radiator supports that the rubber feet fit into I can press the radiator up against the vertical radiator support and i get about 3/16+ clearance at the bottom of the AC pulley. Will the motor ever shift forward enough to make contact?

Pictures of FW clearance, exhaust tunnel, brake booster clearance (none...suggestions?).

This is the first time I have seen the motor in the car and it LOOKS like the intake manifold sits pretty high. Two pictures attached....does this look OK? I don't think i could lower it without new mounts and I only have a couple of millimeters between the oil pan and the e46 steering rack. Does this look like how the motor sits in other folk's cars?

BTW...that is Toyota FIPG squeezing out between the block and oil pan.

Thanks.

Since you're going no AC you can shave off the AC groove on your crank pulley. The other pulleys are set back. It's gonna be tight... I'm running the e28 radiator and that's thinner than the m20 radiator. I have very little space between radiator and alternator pulley. Crank pulley with AC groove to radiator I can barely get a fingers width in there.

[CharMick]

Need to bash the firewall this weekend so I can get an idea of how much room there is.

Since I am going distributor-less I am hoping to have enough room for the radiator to fit in the stock location. It isn't really any wider than the stock m20 rad, just has 3 cores rather than 2 and no provision for auto cooler in the radiator, going with standalone mounted where useless oil cooler used to be.

If anything the pulleys may be close...fingers crossed.

how is your coolant reservoir mounted?

It isn't mounted, just resting there...I probably need to do that.
