My '90 325is LS3 Swap Build Thread

[CLM21]

Got the heads back from the machine shop yesterday and slapped them on this morning. Now just waiting for the rockers which should be here on monday, and various other stuff like windage tray, valve covers, random plugs and stuff which should all be here tuesday. So motor should be done this week.

I don't have the wilwood pedal box. I have massives booster delete and wilwood calipers. I'm not sure if you need to keep them or not with the wilwood setup. But I think mine with a single mc, apparently I need to keep it because the rears lock up before the fronts? I'm not really sure, just what I saw someone say.

Ah gotcha.

Yeah you will want to keep it then. I thought you had a dual master set up going.

The rear brake proportioning valve. It's on the rear line, right after the rear line comes off the bottom of the frame. Where that clip that holds the rear line and all the fuel lines is.

I guess i should be keeping line after all since I'm going non-abs.

Do you not need the rear proportioning valve with the wilwood set up? I guess it's a two master cylinder set up for the brakes?

On my car there is a bracket with cast piece under the master cylinder. The master cylinder lines go to it and from there other lines go to the abs.

What valve meow? I have the hydroboost setup.

Finally ordered the trans and clutch today. Getting a t56 from RPM and a clutch from diamond clutch. Waiting on my heads to get milled, which I dropped off last week, so I can get the motor put together but its taking forever. My damn machine shop guy dropped a ti retainer while putting the heads back together so he had to order a new one and its taking a while. But either way, the engine should be fully together by next week. Should be getting the trans in about 2 weeks. Clutch will be here next week. Also shipped my diff out to get it built. Should be getting that back in 2 weeks. Hoping I can have this thing running by this summer.... full power train should be in by march at least. But im trying not to put anything in the car until I can get all the grease and crap out of the engine bay. Kinda hard to do that when its sitting on jackstands in my garage....

my god.. how have i missed this?

that motor is going to be bonkers

Yeah, I have massives booster delete. Been playing with different MCs and lines this week trying to get the boosterless and abs delete all figured out. Wound up just bending all new lines for the front wheels. For the rear, I removed that valve thats just below the MC on the rear line. Then bent a new line which went from the MC and connected to the existing rear line at the fitting which used to be the outlet of the valve I removed.

Nice. I'm not sure what to do with mine as far as brakes go. I wanna go boosterless but I also want good brakes for DD/Track. Currently riding on stock 316i non vented discs front / drums rear. Might go with a Wilwood 4pot front from Massive.

Huh? I have the sikky kit.... what in the sikky kit removes that valve?

Edit: Oh wait, do you have the sikky hydroboost? I forgot they made that, but I dont have their hydroboost. But I removed the valve as well. I believe everyone that goes boosterless and non-abs removes it. Not sure if it still makes sense to keep it if you have hydroboost or not.

[ultimateracing335i]

The sikky kit removes it. Does that really affect the the braking balance?

[CLM21]

I believe its the proportioning valve for the rear bias

[ultimateracing335i]

What is that valve below the master cylinder.
