You can just remove the pump, cut the lines and plug them for that. I do have an E36 rack going in shortly, I am just waiting on my friend Kevin to turn the spacers for me.

I'm actually moving the engine back 17cm (6 - 3/4 inches roughly) and probably down. The engine pictured is the 'dummy' I built. All internals are removed so it weighs much much less.

Are going to modify the firewall, too? I don't see where you can move the engine 17cm back. Lower is a good idea.

are you going to have to shorten the driveshaft?

robweenerpi · « **Reply #6 on:** February 05, 2009, 09:18:46 PM »

Yeah I started marking the firewall where I need to cut. I will use some sheetmetal to make a scatter plate and new wall. I am running tubes from the cage up to the strut towers and making an x brace from the front subframe to get the strength back.

Yep the driveshaft will obviously have to be shortened. I tried sitting on it but I couldn't get it to fit. I may do a one piece driveshaft.

WOW awesome! This I want to see. I've been thinking the same thing for a while. It seems like the M42 in the E30 sits a lot further forward than M20. I was thinking that the M20 bell housing might be shorter since the block seems to run further back. Maybe you could get away with just swapping in an 260 gear box?

Nope, you could maybe move it back 1/4 or 1/2 inch. It sits in the same position as the other engines. No way to do it without getting into some cutting or welding.

The front of my engine will be at roughly the front axle center line when I'm done.

why?

Why not?

It's a racecar and I'm not running while I'm back in school. Plenty of time to chop it up and put it back together.

Sick! The only thing stopping me doing this to my race car build up is i wanna race it now! and the rules im currently building too of course.

robweenerpi · « **Reply #12 on:** February 11, 2009, 10:26:29 PM »

Here's a couple from tonight's progress.

There is a lot of open space now. I could probably stand between the radiator and engine when done. But..there will probably be a large duct there.

As you can see Cylinder 4 sits basically where the heater box was inside the firewall.

Looks sweet. Can't wait to see the final pics of the engine bay!

I can tell you after putting the engine back in my race car you are going to have hell on your hands...the head will hit the battery box and all that folded junk, you are going to have to cut alot of steel unless you go dry sump and stand the motor upright.

good luck with it thou, keep us updated....lots of room for a turbo up front now!
