      3.2bar!!! man that made me laught simply because of the crazy numbers I am reading. I really can't wait to see this thing fly down that strip.

      What crank are you using, is it a BMW crank or a custom item?

      yeah.. i think the orginal engine block will hold.

      not sure why something has cracked now.. but in anyway it isent due to power.. we did 540whp

      i think i could have something to do with the crash last year.. im hoping that the engine block is cracked and not the head..

      3.2 bars is a lot but not here in sweden :)

      the m20 isent known for breathing well so im guessing we are just helping it :)

      Thanks! Your build is greaT!

      the rear quarter panels are cut on the sides and underneath and pulled out.. then the gaps are filled with sheet metal. the doors are done the same way..

      cut on the back and underneath and filled with sheet metal. i think it ended up beeing around 7-8cm wider on each side.

          The head is scrapped..

          its poring water from 5 different places.

          so all the work we put into it is waste.

          i will now order an factory head.. im tired of broken heads.

            Dam. Cracks? Or Serious Destruction? Or Both?

            So the head gurdle thing didn't really work or was it due to other issues?

            I didn't know you can still order factory heads, I am looking for to pictures of the factory head.

              I didn't know you can still order factory heads, I am looking for to pictures of the factory head.

              my guess is that the job we did on it.. didnt left so much material left.. and when these heads are welded they tend to twist a bit.. and so did this one.. the hening we did of the camshaft bearing sections wasent enough "probably" so when it got warm it cracked.

              the girdle wasent there..i didnt got the longer head bolts that i needed for this.

              i got hold of an aftermarket head from italy.. says that the material in this one should be better then the original..

              im posting frekvent updates on my facebook page. its so much easier when i got all my stuff in my iphone.

              the new head wont be ported as the old one was.. we are just gonna better up the finish.. and then increase the boost map in the ecu to 53psi.. and aim for that.

                Ooh, is it a custom cast or just a modded stock head? Would like to know more about this.

                So basically you fucked the head, and have decided that a stock head with more boost will fix the issue. It makes sense and I understand it but just saying it sounds silly lol.

                    Beautiful car. Which headlights are those? They don't look like regular ellipsoids.

                        The pics you posted on Facebook showed more than a little port/polish. That head looked gorgeous.
