  • Any reccomendations for supporting Shrick 284/276 camshafts?

    Ive heard itd b a good idea to get those motorsport valve springs...i cant find them anywhere! Im planning on putting those shrick 284/276 degree camshafts in the 2.5liter and Id like to know what parts i need to complement these cams. thanks in advance! Hugh

    you should have the motorsport valve springs if you plan on revving past 7500 on a racing kind of basis.

    I have schrick 276/bmw 264 cams in my car. No motorsport valve springs, and I rev pretty high sometimes. No signs of problems, I know people on this board might disagree, but everyone is entitled to their opinions.

    To maximize the power curves with those cams I think adjustable cam gears are the way to go, but many seem to use those cams without adj. gears and don't have any problems, they are just probably missing a few hp without having the adjustability factor in order to get those valves in spec right where schrick wants them to be.

    Check out Motorsport Imports for the motorsport valve springs. I think they are about $400. Maximillians should be able to get them for you as well, but I would try motorsport imports first. It will take you a month to get them from maximillians. My experiences with them is that they have been very slow. Good luck

      you should also consider the motorsport imports kit with the schrick cams and springs.

        you should also know that these "motorsport springs"
        are just the evo3/gr. N springs which you can buy straight
        from BMW. they are stock sport evo springs. real motorsport
        springs have a different designation.

          didn't all cars made after 1990 come with double springs?
          Is the evo springs any different?

            Someone correct me if I'm wrong but all M3 valve springs use dual valve springs. The Sport Evo springs are also dual springs with stiffer rates. They are marked with yellow/red paint.

            I also run 284/276 cams with stock valve springs in my 88 M3 and have no problems. I did this to conserve cost and I really didn't feel the valve spring change was necessary after researching this for while. I may do them later when the head comes off just as a precaution.

                Timing those schricks

                Depending on the modifications to the engine, you may want to change the schrick specs slightly to favor the sweet spot of the cams coming in a little lower. Don't change the event timing spread between the cams, but change when the events occur.

                I have the schricks w/ stock cam gears and I have noticed that the car REALLY explodes when I hit 6,000. I am considering getting the adjustable gears and setting the cams to come in at 5,300-5,500 and starting to top out at 7,000 rather than pull crazy starting at 6K.

                I have a stock 2.3 head and t-bodies. If you have a massaged head then you may want to go directly off the schrick spec as you will benefit from the high rev power band more than I do.

                      Yes - Based on the picture (with the yellow/red markings) and the p/n, that is E3/Grp N spring.

                        Motorsport Imports is no longer around, but plenty of other sponsors or the dealer sell them. The E3 springs are (from what I understand) better than the Schrick springs and are around $400.

                          Somewhere in the 90 model year, all cars got the so called motorsport/group N valve springs that was also in the sport evo. If you have a 1990 E30 M3, you gotta check the paint on the valve springs to confirm if they indeed are the group N springs.

                          I'd take the schrick springs over the Group N Springs... but the REAL motorsport springs would of course be the optimal choice, if your engine build required that level of performance. John, can you comment on schrick valve springs vs. Group N valve springs??

                            Would the sport evo springs be good enough with the 284/276 cams and reving to 8000rpm??

                              Question, The first owner lost the timing chain around 50K miles and had the head rebuilt, that included a full valve and spring replacment, that was done in 95 or so. Is it to my understanding that the dealer only sells the E3 springs? or can you still get the "stock" 87-89 springs? I never knew about the E3 springs when I did my engine rebuild so I never got the check the markings.
