So I know I need a Gen III to gen V adapter plate to took up a L67 to a L26 UIM. But I see some 4 bolt N*'* would that bolt to a L26 upper? could my wire harness plug into that? Would there be too much flow?

no you still need an adapter plate either way.

Thanks 93 for the blunt straight shatter of my idea

Whoops - just saw this. A 4-bolt N* TB is, IIRC, a drive-by-wire setup with a little motor that rotates the throttle plate. That may bolt up or may not, most likely not. but you can't switch to it because it would take a lot of work. You could use a N* TB on an L26 UIM, though, and that wouldn't be too problematic at all. Just as long as you have an external MAF sensor, you're set.

Justin.. if you get the 00+ Northstar TB with the three bolt, all the Gen V to N* adapters work for the L26. It'* the TB that most use, it'* usually cheap to find one.. (around $50) then either modifiy your wiring harness to change the plug for the TPS or get the adapter and add an Lq4 maf and adapter.. you'd be all set w/o any intake restriction.

BTW..please check your rpo'* and find out which gear ratio is in your trans.

Thanks for your input right now I'm going the L67 Route I picked up a 99+ so I'm pretty happy Think would be insane to put a N* on my L36 anyways but insane could be good

Not at all. Your motor will only pull in the air it wants/needs. Surely the N* is overkill sizing for the needs. But what if you go nuts in the future and get a turbo or top swap?

You really want me to get a turbo bill . I'm going mild (aka what I can afford) N/A now but when I graduate that'* when my mods in my sig will take three lines

I dunno if three lines would do it for me currently. We'll have you list it right though. No mention of plugs or wires.. just the real goods.

ready to pull my engine soon though bill almost got all the parts together
