    If your doing the cams yourself (the most challenging part). The rest is nuts and bolts man. Plus, there’s great help here if you have a question.

    So said the 30yr vet a&p, but that did make me stand up and go yeah, yeah I got this lol, cams most challenging, thinking of you and speedy speak of torque types and bolt stretch and you nervous when starting in driveway turns stomach a bit, because I don’t even come close to youlls thought process

    Lol. I was not aware of a process as it pertains to thought......Il try that next time!:D

    The only REAL skill needed is patience, and attention to detail. The rest, nuts and bolts.

    I wouldn’t say better...Carpenter has Megacycle do the cams (good reputation), CP for the pistons (good reputation) and I believe Suzuki parts in the valve train and clutch. What I like about Lush Racing is he contributes here, seems to really get that we don’t all want the same thing and offers choices.

    Bob Carpenter is a genuine dude, easy to talk to and very knowledgeable.

    Carpenter has one big advantage over Nev, *if* you're in the US, and *if* you have the money: he offers ride-in-ride out service on a product he sells.

    If you live in his part of Australia, or, you have a tool set and mindset to DIY, Nev offers much better cost effectiveness in dollar/hp made, especially when combined with good exhaust and intake (as pointed out by @Steel ). And while Nev would like to sell you his cams and tensioner, he will quietly suggest one can go a long way for performance on a 2.3L motor with just the exhaust and intake and legitimate ECU remap.

    Without opening a can of worms about the differences between the two setups.

    Carpenter offers the three setups, but will/can do other things upon request.

    For example, I put a 265 head, milled .1" on a stock bottom end. It made 190 with CES, probably would've cleared 200-205 with the brute/sidewinder. Cams were too big for the compression ratio. When the pistons were done it was a 41hp jump because the cams were now a little too small. Then opening the pipes up gained another 22hp because now the engine could actually use the extra exhaust flow capacity to its fullest.

    Neville has a large number of cams to chose from and can/will match the right cam, cam timing, and compression ratio together so you have a strong but also healthy combination.

    Remember the whole package is a system, from air filter to exhaust tip. What you do on each end or anywhere in between either synchronizes with the rest of that system in harmony or it doesn't. When it doesn't you won't see the expected gains, when it does, you'll get at least the expected amount. This definitely includes cam, cam timing, and compression.

    If you were to do cams first, sized for a higher comp engine, they'll be too large, so you'll have a lazy throttle response, lose a good amount of torque below 3500 and won't see the big gains up top you would expect.

    Best solution to avoid doing things twice is pistons, and cams, at the same time.

    Rob said it better that I did, but it’s what I was getting at.
