Baie nice :P Ek wil die Advance hardloop met n trigger wheel en pickup. mar n 36-1 trigger wheel. Ons(spitronics) doen meeste V8 lexus conversions se ecu's, bou n gearbox management ook wat die triptronic ook incorporate. Hendrik, jou Standard box wat net fueling doen is baie cheap in verhouding met ander. Sal bq uitvind of ons n agent in Bloem het dan gan chat jy met hom.

More manne! my baas het my gister kindoff ooreed. Ek dink ek wil my bakkie Wasted spark run op sy ignition... met 4 seprate coils. Ai ek raak weer opgewonde.

This is my new crank(A15) i'l be trying out soon. You can also see the balancing. Milled and knife Edged.

I will find out 2nite i hope, see im running A14 pistons wich im going 2 have machined down to flat tops. Because of the 82mm stroke of the A15 crank. Will take measurements.

What crown thickness is acceptable?

TJ,dis n 1200 gx head, hy is geport en geflow, mar dis groot ... Dan was hy mooi geskim en nou is hy moertoe geskim so ek moet hom nou lat metal spray, Verder A14 valves. En dan n stel isky springs, mani-fold ports lat match met head. sal as hy nou terug kom photos opsit. Skuld jou nog daai maus se pics ook... :( Goeie nuus is ek begin die week my sub assembly pre-assemble :D

okay lets try : my gx head is currently : 21 cc on in the combustion chamber.

bore will be 60thou so 77.5mm
Stroke 82 mm A15 crank.
(77.5 * 77.5 * 82 * 3.14(pi))/1000 = 1546cc

so 1546/4 to get to a single cylinder would be 386.622 cc

Im running flat-tops so there is no gain except for the small pockets for the valves.

Headgasket if its 2mm would be (if i work on 78mm bore)
78 * 78 * 2mm * 3.14 = 38.207 devided by 4 = 9.55cc

So a single cylinder = 386.622cc
Head gasket = 9.55cc
head = 21cc

Compresion ratio = 386.622 + (9.55 + 21) / (9.55 + 21)
= 13.6 : 1 about.

Is this right ?

So if it is im considering to have the head metal-sprayed back to std spec...
