    ok, just asking( to maybe try them some day) which tires do you think are good for you? I will like to try another type of tires to see how I fell them

          the m20b25 would not be my choice on a track car. after 5000 rpm you run the risk of snapping oem rockers. i'd rather run an m42.

          and with 500 the most you can do is make a reliable m20

          107.17 for the IJ crank scraper
          300 for the ie beefy rockers
          and theat leaves you with 93 dollars for any gaskets and bolts.

          you need deep pockets or time to accumulate the parts for an m20 build.

            I have the crank scraper and about the ie beefy rockers it sounds good
            but first I am going to put the cam in to try it and then i'll see what else I'll go with

                I was looking at the rockers and you are right so I am going to save a little more and buy them, altho I wish I could buy the -M20-Billet -Race Rocker Arm, but they are $85 bux each!!! so I might buy the "Rocker Arm M20 -Heavy Duty Race" they are $25 each, not much

                  on a light duty track car the beefy ones are all you need.

                      actually with the right springs, the IE HD rockers are good even with a highly aggressive cam. most broken rockers are caused by inadequate spring pressure and high mileage, not RPM.

                        It's also always a good idea to save a few hundred for lessons.

                          hey man while you're at it put some NOPI stickers on yer windows. I heard those add like 25+ HP per sticker!
                          and dude, the best thing you can do is get one of those samurai wings. They'll make the car really fast. Don't forget to get a good fiberglass body kit off of ebay. You gota improovee the aerodynamics yo. I say, with those mods and the eta head, you'll be blasting past porches in no time. The hondas might give you a problem though.

                            Just watch out for the crub and the fents. And stay out of the burshes.

                              lol!! hell no!! I wouldn't put a nasty body kit to my daily car, only a splitter under the lip and the small wing from the IS just because I like how it looks. the race car although I have %50 of the opinion because I bought it with my friend but I wouldn't put anything ridiculous and nasty to it, At the most the M3 body kit if my friend want's to put something to it
