E21 Project Thread - Part 2

[Jdesign]

Interesting. I cant wait to see it installed and working! It looks fairly straight forward.

Got more exhaust work done. It's fully welded to right behind the diff as well as hangers created and welded in too. I ordered another flowmaster hp2 resonator, this time the shorty version to put out back. Should work a lot better for the center exhaust with diffuser look I'm going for. A matte black oval tip has also been ordered to finish it off.

Can't wait to hear this thing

Well exhaust is officially done minus one remaining hanger I need to create near the rear tip. Which I need to weld in the pan for the spare tire well before I can do that. I'll get pics then.

Yes. Videos of it running? Burnouts maybe? Or just some nice pictures for now will do.

[Bassboy3313]

It's tough to get pics of the black exhaust tip in the dim garage, but here's the best I could do. I have an idea brewing in my head and some parts coming in the mail on friday to go on either side of the tip too. Stay tuned!

She's alive! But of course where there's ups, there's downs. After firing it up, i noticed a huge fuel leak up in engine bay. I shut it down immediately. Garage floor is covered in fuel and the garage smells horrible. I will need another set of eyes to determine where the leak is. For now I have oil dri on the floor and a box fan running. I will let it dry out/evaporate and hopefully the fumes go away too. Then I will diagnose the leak tonight or tomorrow.

I can't see said video

So Brian and I determined the leak to be the hose clamp on the fuel rail supply line. It's digging into the hose and not clamping it securely. I have the leak at the stupid fitting adapter where the hose meets the hard line, so I'll knock out 2 birds with 1 stone and fix both right away.

Sounds like a smoovve idle. Excited to hear it in person. I hope you get the fuel leak sorted easily.

I have decided to overhaul the (almost) entire fuel delivery system. I have been wanting to get rid of the fuel accumulator that the oem kjet fuel system uses, but is not necessary for EFI and with the fuel hard lines looking a little crusty, now is the time. Here is what I will be replacing..

Remove bosch motorsports external fuel pump and replace with Walbro 255 external pump (ordered).

Remove e21 fuel filter (banjo fittings) and replace with e30 fuel filter (barb fittings).

Remove e21 fuel accumulator, not needed anymore.

Remove crusty fuel hard lines from tank to engine bay and replace with new hard lines. Got a quote from Blunttech for $105 shipped from germany for OEM prebent lines. I will be checking out the napa easy bend lines when I pick up the fuel filter and make my decision then.

Replace fuel hoses and clamps from hard lines to fuel rail and fpr with new.

Sounds great!!

[Bassboy3313]

Had to drop the tanks to completely remove the fuel lines. What a bitch!

I decided to order prebent lines from Germany through blunttech. Going to need a few new mounting clips as well.

Didn't know prebent lines were available for our cars! I searched on a few sites too but not blunts I guess

I've always just messaged blunt and he takes care of the rest. He has found me parts in the past that other places said were unavailable.

Blunt delivers the peen when others say the peen doesnt exist

Not upgrading to 3/8" lines?

I doubt bigger lines will ever be needed for the power levels I will be at. But please do explain your thought.
