200 4r upgrade kit

geckonz08 · February 27th, 2009, 11:58 AM

Really considering a 200-4r upgrade.Have one in good order already sitting in the caddy which is getting a 425 toro engine .This motor will be only slightly modified -ported heads ,O4B intake , custom headers , slightly better cam .
Would the upgrade kit (below) bring the 200 4r up to speed to handle the 425 ??

Thanks mike

Not even close. The turbo Buick community has found and fixed more failure points in the 200-4R than you can imagine. At an absolute minimum you also need a heat treated stator shaft and a forward clutch drum with a steel billet shaft. I've busted these parts with a 307. Depending on whether you prefer an east coast or west coast vendor, here are two of the best for 200-4R parts:

Thanks joe -that is a great answer . Left no room for doubt.!!!

Probably the west coast because I can get the kit sent to my brother`s L.A. address.

I wouldn't call this a Kit. You need to replace numerous hard parts.

Tell Art what you want, and have him put it on "Will Call" for your brother to pick up.
