'89 316i E30 LS1 Swap Build Thread

Sounds pretty good for a single exhaust/muffler setup. The Varex system lowers the noise levels nicely when the valve is closed.

Got a used IACV i'm gonna test out tomorrow. I cant run the engine much since the PS pump is pretty much dry right now. Hoping I can finish the rack and diff before the 18th.

New start up and idle video with the X-Force exhaust setup. This is with the exhaust valve open.

New IACV installed and working perfectly. Rebuilding the steering rack atm.

How did the headers line up, did they fit or did you have to modify them?

[Q8y_drifter]

They technically fit. However to fish the driver's side in between the engine and frame was probably the most difficult part of this swap. Passenger side slides in no problem whatsoever. Drivers side I had to

Massage the shock tower support
Remove valve coils, valve cover and plugs
Loosen engine mounts and pull/tilt engine towards passenger side.

They barely squeezed in with a lot of swearing, hammering and twisting.

The collectors will need to be cut/shortened if you actually wanna drive this thing on a road. They are too long and extend right towards the ground.

So I rebuilt the rack with new seals, bolted it back in, started up the motor and the POS still pisses fluid. So I picked up another Z3 rack and a non-powered Z4 rack. My guess is the top shaft on the Z3 rack is fucked so I'm swapping it out. If that still doesn't fix it I'm going with a manual Z4 rack.

E30s are just so tight. It saddens me how little space there is to work with. I can't imagine someone adding a turbo in the bay with a V8 anything. Call me old, but I like to engineer my stuff so it's easy to work on.

That's part of why I picked up an 85 cutlass about a month back. Picked up a 5.7 LS1 for it and already got most of the swap parts ready to install. It's gonna cost me about 1/10th of the E30 swap lol
