KE70PWR Posted July 27, 2014 Report Share Posted July 27, 2014 Hi all thought I would start a bit of a thread here with my rolla. I bought the rolla about 5 years ago now and had been driving as a daily until i had a work car so started to do some work on her. I pulled the motor out and did a rebuild myself (lots of learning). Tried various combinations of carbs from stock to weber also tried twin SU's worked great but my cam was to lumpy so did not work so well at idle. Anyway moved to Sydney and the car stayed here in QLD and unfortunately had to be stored outside and very quickly grew rust and was not quite the same. However I have now moved back to QLD and have decided to get it back on the road and make a project out of it. I am going to keep the k motor but make it a turbo blow through set up.

KE70PWR Posted July 31, 2014 Author Report Share Posted July 31, 2014 on the weekend i got a few bits installed. Cam new cam chain and gears new double springs. its coming together now. next step is to get the j pipe finished and make up the oil and water lines for the turbo with a custom return plate for the oil where the original fuel pump came from. any one has any suggestions please share as I am only fumbling my way through. :) Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted July 31, 2014 Report Share Posted July 31, 2014 What's the story with compression ratio and boost?? How much boost will it take at the stock compression? I'm not a turbo man, but some guys on here have done it all & I'm sure they have sorted the problems with that. Quote Link to comment Share on other sites More sharing options...

7000rpm Posted July 31, 2014 Report Share Posted July 31, 2014 Very clean build mate. I remember going for a run in a gemini years ago that had a blow thru 32/36 weber, far out it went hard! I have a t28 turbo off my s14 if your interested? Keen to see this build come together, good work Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted July 31, 2014 Report Share Posted July 31, 2014 has anyone done this to a electronic dissy? I doubt that you can, athough I'd love to find out that you can! The Hall Effect sensor tells the dizzy when to fire the coil, the dizzy software reads the sensor input against time and it ramps up the advance according to a fixed curve. To play with the timing you need a programmable ECU, which these days you can buy I think. Just use an old mechanical dizzy you can lock. Sell the electronic one for a hundred bucks or fit it to another 4K. Quote Link to comment Share on other sites More sharing options...

KE70PWR Posted August 3, 2014 Author Report Share Posted August 3, 2014 Ok so pulled the dissy apart yesterday and looks like there is still 2 springs and weights that advance the plate when the revs come up so I will wire these together and give it a go and see if that works will keep you updated.

widomski Posted August 3, 2014 Report Share Posted August 3, 2014 Super keen to see how this project pans out! I recently got a spare 4k and k40 gearbox for $20 so a turbo build that I can swap straight into the ke70 is on the cards. Any particular mods to the 32/36? Are you fabricating your own exhaust manifold? Photos, photos, photos! Quote Link to comment Share on other sites More sharing options...
