The OFFICIAL 24v Engine Bay Thread

there shouldn't be a problem since it's just the expansion take which doens't take much pressure. i've checked the system and it's working properly, it's really not that bad in person i felt the hose after the engine heated up and drove around the neighborhood a few times, all is fine. I guess i can always wrap it in some insulation. I'm trying something different, i guess it could blow up in my face or work just fine, not like took off my front brakes to drift better;)

I removed my e30 m3 tank and put in a "i" tank. There's no room to run a hose behind the engine. I'm tempted to do what Tony did, but the "i" tank works nicely once you get it mounted.

[tjhartge]

You could use an S14/M3 expansion tank and some hoses. I believe they are routed behind the engine.

i have seen on another car, i can't recall which model, that had a metal tube that resembled the coolant hose that's mounted across the lower part of the radiator, think this would be a safer bet rather then having the coolant hose running for a very long length

i believe the expansion tank should be at a higher level compared to the engine as this will ease/help coolant flow and pressure
anyone care to input?

tony
please check if your expansion tank is releasing excessive coolant after engine is cooled down

[tonytony]

coolant level is a bit higher when car is warmed up but nothing to be alarmed about, I'll take better pictures tomorrow, it just the angle it was taken at.

I have a few things to sort out, but it drives fine for now. I am looking forward to connecting the rest and cleaning up the engine bay a little (wires and such). I am going to make some brackets for a few things soon as well. I am very happy with it so far. :)

looks greasy, but nice:up:

///Mpressive, noticed you don't run the mechanical fan. Do you just run stock aux fan? or you have bigger electrical fan in front?

Currently not running a fan. I am on the look out for one though. I am not 100% on what I'm going with either.

Mrpessive:
OBD1 or OBD2 assuming that is the 3.2 litre

If obd1 how was the conversion? Run into any difficulties?

[matt]

It's OBDI. The conversion isn't hard. The motor fired up first try.

wow, i like that air filter setup //mpressive! where did you get it?

Thanks. I made it from some piping that I bought. I cut it to size and added a cone type filter. Total spent - $35.

What you can't see is an 5 inch intake airhole under the filter that pushes cool air directly into the filter.

I bet that intake setup makes a nice noise! I bet it's quite torquey too.

Intakes are so much easier to plumb without that pesky ABS pump. Has anybody tried to relocate it?

i did see a racecar with the abs pump in the battery tray. i will look for pics. the only difficulty is finding a flaired end tool that does the bmw "bubble" end fittings. jason
