    Regional rally mechanical problem!!!

    I just finished 14th in a regional rally and blew a head gasket, I am mad and need a to get some power to kick some subaru's ass!!!!


    The setup is a 4wd bg with a stock gtx, 3 inch exhaust....


    So the questions are, what kind of head gasket replacement would you suggest ( regular or metal ) what kind of intercooler do you guys run and any suggestions on thing to modify while the head is out!

    Also while I am in the cooling system, I need a new radiator, probably aluminum one, there again what would be your suggestion.

    And while you are at it you guys know any good internet shops to order bpt, protege, and rally specific parts?


    Thanks
    If you guys wanna see some of the pictures of the weekend

    there r aluminum radiators on ebay now, just search "mazda gtx"

    you should only need a medium size FMIC and 14lbs of boost and u can probly make 200whp since u already have a full 3'' exhaust. what other parts were u looking for?

      The oem 1.8 headgasket is mls (multi-layered steel). The 1.6 is not, but Flyin'Miata sells a metal one for it.

        I'd rather lose a gasket than a head...

          swap on a N/A head for better flow, and put the bp26 cams in it.

          put the GTR intake manifold on it.

          look at getting the CS downpipe if you don't already have it.

          do you have the stock GTX AFM, or the RX7 B-code AFM?

          depending on how rules are, you can take a stock exhaust valve and put it on the intake side and then get adjustable cam gears.

          also, depending on rules, you can try and source a vf10 or vf12 and bolt it to the hotside.

            Depends entirely on the class he's running. Exhaust should be open. So shoule IM.

              if hes already turboed the pro 4wd then hes in a mod class and intake mani, MAF, exhaust and cams shouldnt matter

                Yup because of the engine swap I am in open class, so mostly no rules other than the security ones........

                I have a gtr MAF

                Exhaust walve in the intake ????

                And a stock head gasket..... don't be mad but what about the ebay kits (probably a bad idea) but still maby a cheap alternative...

                What about head studs, worth it ???

                And if I am going to get the cam gears any receipes on adjustements, I think I can put my hands on some b6t cams....

                And thanks for the fast answers

                  You could argue that it's stock in japan if you really wanted to putting you in... PGT or equivalent, depending on governing body of course.

                    ok open class is good news then, u need JDM tranny with lsd center diff, GTR rear diff, FMIC, remove the front sway bar, then just turn the boost up and u shouldnt have any problem kickin subie ass(as long as u arnt a sucky driver)

                      Agreed. I'm just trying to get you to run a lower class to give you the edge.

                        B6T cams won't work in a 1.8.

                          lol, i'm likely to move up a class next year just for changing tires... i keep getting 3rd and 4th ish at all the evets.. but if i was up 1 class, i'd be faster than the next car by average of 3-5 secs...

                            Awriiiight. Someone else rallying a bg awd protege. If you're in Open, do you have to run the same lameass 34mm restrictor we do in the states? If so, running anything bigger than a GT28R is a waste of effort. A GT25 is prolly about right, especially if you get rid of the maf and go standalone. So go on the small side for a turbo, less lag is good. And if you can't beat 'em with power, beat 'em with brakes. Our cars weigh less than those sti's. Take it to them on the entrances. Get as much brake as will fit and use Porterfield R4E pads. If you haven't already, get rid of your swaybars. Now to get to some of your Q's..
                            OEM headgasket should hold up just fine. I use Felpro though.
                            I'm using an oem radiator, with a pair of Spal fans, so far so good.
                            I get most of my stuff through Corksport, 'cept for my suspension which was fabbed up by a local guru.
                            Don't scrimp on the intercooler. I'm using something made for some manner of hotrod DSM, it's pretty good sized, has a fair amount of thermal mass, and is watersprayed.
                            I don't think playing around with cams is worth the effort, just turn up the boost. Unless of course you go find some trick WRC style ultra high lift cams to try and work around the restrictor...I, ah, haven't found anything matching that description though.

                            Oh yeah. One other thing. Those BPT rods aren't as strong as I thought they were. If you plan on much more'n 18psi you best do some bottom end work while you're at it.
                            '90 AWD Protege, full GTR drivetrain swap, ~320 whp daily driver, RIP, and
                            '90 AWD Protege, yet another GTR swap, Open class rallycar with a Toyota GT4 gearbox swap, thus crossing the line between hobby and mental illness. And a Brabus E55 K8, removing all doubt.

                              Since I only have the $ to run rally-cross events right now so no restrictor plate, actually no restrictions other than security ones, but will surely end up in canadian championship with the restrictor plate.

                              Remove both of the sway bars ????

                              What kind of boost can I go to with stock injectors and and block 15 psi???

                              What about the miata diff a friend of mine told me it fits right in.

                              For the suspension I have a 325 lbs front and 225 rear coilover springs and bilstein inserts for vw golf mk2 (welded the upper part of the struts of the wv to the buttom part of the protege strut, actualy a friend of mine did it hehe) What do you guys think of that ???

                              And for the intercooler I think somebody on this forum made a bolt on kit...

                              Little questions, what kid of oil do you guys run (block trans and diff) and what would be a ''normal'' oil and water temp and oil presure durring race use. Trying to get to know my new toy a little bit more....
