btw, sorry for the big threadjack, you're definitely on the right track with your build, but don't forget the suspension! (psst... I have a set of AST 4200s for sale for a good deal...)

When Vorshlag starts working on the custom catted downpipes for the shorty headers I'm planning to use, I'll try to update with that info, for the benefit of everyone else. =]

Guess we are gonna go OT, I've been trying to get some measurements... are you talking about TMS shorty's? I think they will fit, would just require some fabrication to get them to merge? I'd love to be educated more on this topic Tiny teaser update. Also took off the bumper today so everyone can see better.

Yeah, the TMS shorties, which were designed for the E36. They should bolt up ok, and I think they'll fit, and Vorshlag is planning to work on some custom catted downpipes for them for me. They should help with torque (ok, not hard vs. stock!) which is what I need for autocross purposes, as we don't spend much time at high revs.

Some recent emails I've received indicate I may not need to go quite that exotic, but we'll see, awaiting clarification from the appropriate rules folks...

Good info, I was thinking the same on fitment. Please keep me up to date on whats going on with that. Very interested.

Finished maintaining the fuel system. Parts otw are oem radio block off plate. Gas pedal mount. (broke the last one ) few nitrous jets. Lots of body plugs. This is the only update today. What do you guys think? Run a 90 degree fitting off that T towards the motor? Or just a line will be ok?

Again, use the Shortest possible 3an line from the fuel solenoid to the nitrous/fuel single nozzle.
I see no difference in either choice, they're both being fed from the same fuel pump/system. A single nozzle spraying up to 75 hp should never need a separate dedicated fuel system. If you go to a DP system, then you could start to entertain the idea of a stand alone 1 gallon fuel cell with its own pump & regulator.

Good luck.

Agreed no secondary system required. Guess I'll just run a line to that fitting as planned. Are you implying I should have tapped my rail? Instead of after the filter and before the rail?

I can't see a difference, we're only talking about a small amount of fuel usage.

Am I missing something ?

I got some cheap fuel hose at auto zone rated for 3.5 bar.. Think I'm asking for trouble? Kinda bugging me, I think I should get some oem line? The oem line had two layers and seemed stronger.

Depends on what pressure you planning to see...

I'm gonna go to oem lines just to be safe. I just realized, I have several feet of that hose from all the fuel rails.

Little update, ordered a Single Probe EGT, CHT, dual guage. From The Sensor Connection. Spoke to a man this morning, very polite and entertained my game of 20 questions Peak hold, with alarm. Should have them in by the end of the week! Anyone wanna save me some driving/testing on which cylinder is the hottest? https://thesensorconnection.com/cart Edit: Fed ex man just showed up with these! I now have 55 to 175

EGT / CHT, great safety device, very useable with a nitrous application.

Question: did you buy the one with the single analog EGT/CHT gauge which only has a "LCD Pointer Resolution: 50F". Or, did you buy the one with two separate single Digital displays that have a "Resolution: 1F" ?
