Ian's E30 LS1 Swap

What front splitter is that? Thanks

The splitter is custom cut from a flat piece of dibond that was CNC cut locally with a 2D file that I made in Fusion 360. I’m thinking of going wider with the splitter in the near future.

E30 is officially in hibernation mode. Compression checked the engine last weekend and all cylinders were between 170-180 psi (forgot to open the throttle body during testing). Planning to leakdown test the engine soon as well (hopefully this weekend). Best case scenario is that the PCV system needs to be reworked/vented and the engine doesn’t need to come out.

Goal is to get the interior out, pull the bolt-in half cage, weld in a full SCCA cage, and rework wiring.

Hey what’s up brother! I try to keep the thread going for information and updates. I’ll definitely need to check yours out! Hope all is well.

Performed the compression and leak down tests and both surprisingly came back better than expected. Compression (without the throttle body open because I forgot) was between 170-180 psi on all cylinders. The leak down numbers were between 2-6% on all cylinders. So super happy with the results.

Next step is fixing the PCV/venting system, pulling the fuel hard lines to install 37 degree flare fittings to the -6an lines to get rid of the hose clamps, hook up the Accusump finally, and heat wrap the brake/clutch lines. Also, planning to order some Jongbloed Racing wheels here in the near future. Than back to testing.

What Camber / toe adjusters do you have?

I have an assortment of ground down wrenches for E30 alignments. They need to be TIGHT.

Were you able to do a compression test hot?

I’m using the serrated camber and toe adjusters. I need to get the car down to a friend’s shop that has the ground down wrenches for the job too.

Compression test was not hot and did not have the throttle body open. Didn’t feel like trying to pull the plugs with a hot engine bay. Results were still decent.
