Thought i would post up some info of my car..

Its a 84 FB, bought it from a mate and its got 36,000 on the clock.
I originall was going a NA injected set up but decided that 140-160hp wasnt enough when ive been use to 400rwhp in a 800kg car..

I originally had the engine ported and built by Era De Klerk with hurley 1 piece seals.. The car would not start and was an absolute ball ache to try and get running even with a tow start.. the engine with a mazda comp tester showed 40psi both front and back rotors.. I will not be using hurely junk again - Mazda all the way!!!

So after 6 weeks of playing with the car i decided to pull the engine and rebuild it myself with some mazda 2 piece 3mms. I put the engine back in and the thing fired on the key with the same tune..

All of the work on the car has been done by myself: exhaust, wiring of ecu and gauges etc , intercooler piping etc..

Hope to get some miles on the new engine and get  a good tune in it.. The car should make in the 300s on 12-14psi, hopefully high 300s or low 400s with water injection..

Here are some pics..

hey damo - how big is the cooler you put up front? looks neat and tidy.....

Its the same width as the 3 row radiator that i put in it.. Not sure but if you want the dimmensions for the 1300 let me know..
 
Also this evening i did a compression test on the engine this evening.. The engine has about an hrs running time and no road miles as yet but was well happy with the result of 100psi cold front and back compaired to the old engine with the .... 1 piece apex steels that produced under 4 bar !!

I knew it would start on the button with 2 piece Mazda seals! Glad you decided to junk those useless hurley apex seals before they damaged your housings! Have u still got them? might cut them down and use them as toothpicks. Those are fantastic numbers on the Mazda 2 piece seals which will get higher as you put more miles on her. Cant wait to see it all mapped up...might have to pop down again!

yeh man thanks heaps for poping past to do the comp test for me..
 
once ive run it in well do another comp test to see how it with some miles on it..
 
As for Hurleys - i feel like posting them back once if bent them into a shape and saying thanks for the piece of shyte product and they arent worth the £10 piece of mild steel they are made from !!
 
Heres a vid of how it starts now after this 6 weeks of head banging to try and get it started..
