    RIVA Titanium retainer install on my GP1800

    I just completed the install of the Riva retainers on my SVHO engine. It's relatively easy with the Riva tool. Figure 3 hours to remove the camshafts, install the retainers and reinstall and time the camshafts. Having an extra set of hands really helps when doing the retainers. It reminds me a lot of playing that game Operation when I was a kid

    It's amazing how much lighter the Riva Titanium retainers are on. Pics below for reference.

    Now the engine is safe to rev 9200+++ RPM which will bring on some even better speeds and even better acceleration

    Here is what you will need to do the job

    I used that same tool when Rich and I did the retainers on my ski. I have no idea how anyone could do that job without the Riva too.

    I thought you needed to upgrade the oem valve springs with the retainers to run above 8600 rpms?

    Not at all, just using the Riva retainers with the stock springs are proven to 9400 RPM and in some cases guys have run even higher than that.

    thats an expensive tool! anyone is South Florida willing to lend tool to install retainers?

    I called my local shop and they quoted me 7-10 hours labor to install the new retainers. @ $85/hr labor, it makes getting above 8600 rpm a little pricey

    I was charged $750 retainers with installation. He said he would need 4hours.
