That's what I manually add img tags to. mt.nets server caches and renames whether I like it or not. Might have something to do with being a site sponsor/advertiser. It's definitely a site glitch. I post inline images on forums all over the world, two of which cache and rename. The only site that has display issues is this one.

It's not complicated. Add img tags, done.

I agree. MT has some odd quirks. I find that it does the caching only on thread/post creation, but not on an edit. This makes it a really odd/bad in the case that you upload the wrong pictures or shitty quality and want to change it.

Would this work on a stock 94-97 ECU for swapping in a NB engine and intake (no trubo)? IIRC, the NB injectors want a higher base fuel pressure, but will the stock ECU negate any benefit?

Yes, yes, I know, programmable ECU.... But I haz engine on stand that is sad and wants zoom zoom.

No.

Option #1: Use stock NA8 ECU and realize most of the benefit of the more powerful engine

Option #2: Use programmable ECU and realize all the potential of the more powerful engine

Fixed fuel pressure regulators are for increasing total fuel mass, not fine tuning AFR's.

Fixed your images. Not sure why you were having problems, I just went through the normal "Manage Attachments -> Upload File from a URL" dialogue using the links you posted in #18 and it worked fine.

I'm going to take a wild guess and say that I'm not injector limited on a VVT swap with NB2 injectors, NB1 fuel rail, and an upside-down 1.6L FPR on 93 pump gas?

Really interesting stuff, regardless

Dunno. Got a way to measure D/C? My guess is you're OK. E85 would probably not be and that's where the NB FPR trick comes in handy.

Ultimately, everyone reading this thread needs to do the homework, not just ask me. rceng.com has a good calculator. RB Racing does too.

Learn what BSFC is and what is a typical value for your build
Measure 02
Log injector D/C
Buy a cheap mechanical FPR and stick it on the fuel rail
Whip out the calculator and do some simple math

Asking guys on forums if you have enough injector/fuel pressure is asking how to blow up an engine. You must become your own expert to avoid combustion sadness. Trust me.


Almost forgot!
