Hey all,
I was very fortunate, found an ad on craigslist for a 2005 Pontiac Grand Prix supercharger. Drove through rush hour traffic in Nashville to meet him... sure enough, it was a Gen V M90. Paid him his full asking price of $50. It had the bypass valve, but was missing the vacuum tree.
Another turn of good luck, pulled a throttle body off a 2001 Cadillac Deville at the local pick-n-pull yesterday. $35 for the throttle body with all the electronics (kept the connectors on the TB, just cut off wire as far from the throttle body as I could). Also picked up the MAF ($20) off the same car. I believe it's the same as an LQ4, someone may have to correct me. It seemed to be in great shape. Also grabbed a vacuum tree off an L67.
Hoping continue this project spending as little as possible. Not in a huge hurry to put it all together, thinking of saving it for my next L67 car.
So, I am on the step where I need to pick a throttle body adapter to join the two. I see that various vendors sell them for $100 apiece, wondered if there was a community member somewhere that builds them for somewhat cheaper. I'm keeping an eye on the for sale section for a used one, maybe I'll get lucky. I'd strongly prefer to get one with a functional EVAP.
Also, how hard is it to modify the l67 throttle body bracket to work with the N* style? Can it be done with just some bending and dremel work?
How different is the Gen V LIM? I know it is said that you can machine your Gen 3 intake manifold... how involved is that? Does the inlet just need to be cut open bigger? I have access to a mill. Do the bolt holes need to be relocated/tapped?
I intend to put a ZZP MPS hub on the end before installing it. I have used the ZZP removal tool and it works great, but is it really necessary if I have no intention of re-using the stock pulley? Will a regular gear/pulley puller work without damaging the snout assembly? (Again, don't care about the pulley)
Finally, wiring. It looks like the various adapters for the MAF, IAC, TPS are just female L67 connectors attached to the N*/LQ4 connectors. Is there any passive electronics I need to be aware of here? Looks like I just need to pick up some connectors and just do some re-pinning.
Thanks in advance for the help, guys.
