    Throttle body improvements & misc.

    Looking to gather some more stuff over winter hopefully.

    '00 WS6 m6, not daily driven, 102k mi, all stock aside of GMMG catback, suspension, and SLP lid/smooth bellow.

    So i'm hoping that over winter this will be what I get done with my car. I have used GTP longtubes on stand by, and a new TSP 3" OR/Y that was free with them ( currently trying to score a used Kooks 3" OR/Y for a good deal on Facebook, and gonna sell the TSP. Read that Kooks fits QTP better & QTP are a replica of Kooks ). Once that all goes in, I have the good copper plugs, MSD wires, an LS6 intake w/ new seals, and prothane engine mounts ready for install.

    While torn apart, i'm looking for what is worth replacing or what is necessary along with this project. Was thinking about trying to have the stock 78mm throttle body port and polished to 85mm. Not looking to buy a replacement 90mm or anything like that, figuring in on the LS6 intake and not buying a pricey Fast Perf one. Not considering trying to P&P it myself either. But unaware of the cost of P&P, is it worth it do P&P a stock TB? Or is there an aftermarket one worth buying for a few bucks more? I have heard of 5 rwhp gains on a stock P&P, but an aftermarket P&P throttle body seems to be around $150. Looks like the avg cost is around $70 for P&P.

    Also was planning to swap the LS1 fuel rails/injectors over to the LS6. Should I order larger injectors? I would be looking to do a mail-order tune after it all as heads/cam would be a distant future goal ( like after a rear end and transmission upgrade goal ) but if injectors should be upgraded here, would certainly like do it correct the first time until future head/cam work.

    And lastly, my research has concluded that oil pump and timing chain can be left alone until attention is either needed, or until the car is cammed. That good? And I believe I would want to do a P&P LS6 oil pump & LS6 timing chain. That the right way to go?

    I'm looking up MAF stuff currently, some folks de-screen them. Mentally I don't like the idea of that. Would that be ok to do to my non daily driven car? I still enjoy the car on the road in the summer months but I can't imagine anything thick would get past the air filter.

    Tried some research before asking, but always like reassurance, suggestions, and the changing times & new parts out there is always worth an asking. Thanks!

    There used to be a guy that did them S2 Performance, however his site is no longer active so I'm not sure if he's still around. I and I believe Orion too had one of his P&P TB's. You may try a local machine shop to see if they would do so. BBK used to sell a 85mm TB that had mixed reviews.

    Also was planning to swap the LS1 fuel rails/injectors over to the LS6. Should I order larger injectors?
    No need unless you went up to a stroker or better cam & heads.

    I would be looking to do a mail-order tune after it all as heads/cam would be a distant future goal
    For simple bolt on's Frost is the tune to get. For cam and Heads you'll need a full on tune session otherwise you risk damage to the engine.

    ( like after a rear end and transmission upgrade goal ) but if injectors should be upgraded here, would certainly like do it correct the first time until future head/cam work.
    The 10 bolt is to me the biggest crime against our cars from GM. Should have come with a 12 bolt. You have quite a few options when upgrading the rear. 9" would be for heavy track use, 12 bolt for good mix of both street/cruise/track. 8.8's are kinda in between the 9" and the 12 bolt. A few companies are making them now, I made mine before they started selling them. So far after 2+ yrs it's been holding strong and I've not been to easy on it either.

    And lastly, my research has concluded that oil pump and timing chain can be left alone until attention is either needed, or until the car is cammed. That good? And I believe I would want to do a P&P LS6 oil pump & LS6 timing chain. That the right way to go?
    Oil pump - LS6 or Melling 10295 pumps are good. If you go big on cam and heads or go with a bigger block then I suggest the Melling 10296 (HO/HV)
    LS2 timing chain and call it done. Double rollers are a PITA to install and I wouldn't go that route unless I was boosted or high Nitrous/C.I. build. Now there is a timing chain dampner from Trick flow that would be worth the $45 to install. Do all 3 at the same time if you decided to cam it.

    I'm looking up MAF stuff currently, some folks de-screen them. Mentally I don't like the idea of that. Would that be ok to do to my non daily driven car? I still enjoy the car on the road in the summer months but I can't imagine anything thick would get past the air filter.
    I strongly do not recommend doing. De-screening it doesn't add any real measurable HP gains. And IMHO only makes it easier to suck in trash.


    Anything else feel free to ask. It's what we're here for.

    Unless you go with a Speed Density Tune.


    I really need to think of a way of inserting a screen after the air filter.

    So much crap on the roads that I don't quite trust a paper filter. And with me having a SD tune I have no MAF.
