shit i love this car

Thanks

any updates on this ??

Yep, plugging away at it in my spare time!

After a bit of back and forth with PWR and lots of measuring a radiator arrived. Looks pretty good and fits well.

I've also collected most of the materials for the header tank and swirl pot, so a few trips to the fabricator and it should be going again. Hoping to give it a shake down in the next couple of weeks.

Well it's been another painful few months. Got the radiator and new swirl pot + header tank combo in, fired the car up and it promptly dropped two cylinders. Turns out the cdi had dropped a capacitor so it was sent back to Autronic for repairs. Autronic strongly recommended upgrading the chip in the ECU since I'm about 5 versions out of date so I elected to do that at the same time. What a massive mistake that turned out to be!! Two additional trips back to Autronic in Vic, three SM4 chip versions and three or four months later and it's finally running again.

I got it down to MC Motorsport on Friday for a test & tune session. Running only 1bar and revving to 6k it still went pretty well. Having a bit of a problem with oil surge under acceleration which is odd considering it's fine on the street - I'm hoping it's the sump running a bit low with sustained high'ish rpm resulting in surge since it's an easier fix than pulling the sump off.... The accusump looked after things but nevertheless I need to get to the bottom of that one before I have another crack.

Some in car video from the shakedown, taking it pretty easy on account of the oil pressure.

It's heaps of fun and should be even better once the cam timing has been sorted out with a bit more boost! Peter Gray built the engine.
