Default N* to L26

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.

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?

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.
