yep the only thing that comes with the 90mm is the cars. i think the ZR1 is running a 87mm if i remember correctly.

if you can get the TB for 100-150 i dont see a problem with it but if your finding them for 200+ id just stay with what i have imo.

 

Didn't know you could find them that cheap..scoggin wants an outrageous number for them, which is as far as I searched. I'll keep my eyes open though, sure it couldn't hurt a cammed and CNC'd 5.3 I'm putting together.

 

no itll help! check ebay, craigslist, LS1tech

 

I like the mod if you can get for under 175 bucks... Throttle is more responsive since I changed from 87mm to 90mm. Be sure to get the correct year, the 2009-2010 TB's open the opposite direction, not sure if they would work on your 2007. The stock 2009-2010 TB's also have smoother/more machined stock bore...

They have 3 left here for 154 bucks each... http://cgi.ebay.com/ebaymotors/ws/eB...5855&viewitem=

 

theyll work, skipperdaddy has the LS7 (newer yr model than mine) bc its smooth an opens different than mine

 

Can one of you confirm for me the connector on 90 tb is 6 pin? in the pic Mark sent a link of, it only shows 3 pins at the bottom, but the tb is angled, I just pulled the connector off mine and it has 6 pins.

 

mines a 6 pin, and so is skipperdaddys

 

It's a 6 pin, just the bad pic angle like you assumed...I got mine from the same ebay seller/same part #...Hopefully it work on 07's...If not you will have zero problem selling it on ebay for the same price...

 

or hell even on here!


Mark have ya been back to the track yet??

 

No, I haven't... been tied up with the boat getting ready for red snapper season (opens this weekend). Trying to catch my fish now before the oil spill moves too far west.

My bottom end picked up nice after adding headers. Can't wait to tow..
