im in UT too.. also have an S54 swap... GET THAT FILTER OUT OF THE ENGINE BAY ASAP!!

we have done extensive testing with intakes on many S54 swapped E36's and we saw 136* intake temps with filters in the engine bay.. was pulling all kinds of power and timing. either sink that filter into the bumper and pull the fog light cover for fresh air or use a SPECTRE shielded intake air filter.. we now see 2-3* above ambient, even in summer up here in UT

Interesting, I have never heard this. My car has always performed flawlessly with the filter in the engine bay, albeit with a nice custom heat shield. Recently dyno'd at 329 rwhp and 256 ft/lbs.

Run INPA, or something while driving to scan you IAT’s, once moving fast it’s not a huge issue but around town, ours got high

Ok. My car is a race car, so around town drivability is the least of my concerns. Apples and oranges.

I've done a bunch of temperature logging, and despite sucking from the engine bay, my intake temps are ~ambient by 10mph. 0-10mph is traction limited even on hot R comps, so I've never really cared that I'm not making full power there.

Add another to the e36/s54 category. Done using all oem parts, a mix of z3m s54, euro e36 m3 ( ac stuff) and e46 m3.
210k on the shell. 1500 on all suspension/ subframe components/ 80k on the motor ( vanos bearings and all gaskets and seals changed while the motor was out). SS headers, ss resonated section 1, ss csl 2.5 inch section 2 into a bimmerworld rear muffler.

Clean, where did you source the unobtainium z3m air filter box?

**smee123** · 03-31-2021, 03:54 PM

Thanks for the kind words. The box was direct from Germany along with the rest of the front end ac and plastic parts. Only thing non oem is the condenser fan, which is driven by the e46 m3 ecu via pwm. All the relays and the fuses are in the e36 fuse box so nothing stuffed in the e36 dme cubby. Z3m s54 cluster also to simplify the wiring.

I also used an oem e36 m3 evo oil cooler and oil cooler duct. Those are critical.

How long did it take you to do all the wiring on that?

**smee123** · 04-03-2021, 03:17 AM

It took a decent amount of time as it was fairly tedious. The power wiring needed to he extended to reach the fuse box. Tye swap harness was made longer to locate the fuel pump relay in the fuse box already. Switched to the turner intake over the course of this week.

Fantastic work fellow Estoril brother. I almost went with the Turner box too

**smee123** · 04-03-2021, 04:44 PM

Fitment is tighter than I would like but so is the factory manifold. Now the fk csl filter is holding me back.... plan to order 3 more once turner gets them in stock.
