4agt/ze Engine balancing and building?

yes you can laugh poo head

Car will be used for anything it wants to be used for- mainly getting the shopping and blowing stuff up.

yeah true bazda- 230kw is about 350 fly, but i was confused and thought the dude was running 243 kw, not 234. which is closer to 375. anywho, 5 pound boost extra should net at least 25 extra horse.

Your car if running 20v head and 7a bottom should be able to get into the 300kw atw area youd think, mega pwer for fwd, un frickon beleivable drivability!

yea lol, I will find out in about 1-2 months time.
what rods are u using and u just using the gze pistons?

[crnkin]

just using the high comp gze pisons, with the mad thickest gze rods, stock the rods supposedly are good for 400, so with a bit of balancing i hope theyll take 400 everyday, and the pistons, well, they will be at the limits, when i go to the states i may look for some wiseco's or something, but they should be fine for 22-25 psi

[Bazda]

Well I wouldnt circuit race that car then, blow up big time. Ok for road/drag use.

[crnkin]

nah wont be on the circuit, just drive it round everyday, maybe start drifting, but i wanna ke70 drift car if anything, i couldnt stand crashing my at141 id never be able to replace it!

[neon_spork]

Im just finishing a build to simular specs but with a RNN14 T28. I found the gze pistons all weighed exactly the same to .5gms which is bloody good from factory. With a good set of scales and a bit of time its not that difficult to get pistons and rods weighing all the same.

Although balancing is not simply having each rod weighing the same, it means that the center of rotation of the rod is also the centre of mass so that no unbalanced forces are created. Also some unbalance can only be detected when the component is rotating (dynamic inbalance) so you need a mahcine to find it.

drifting, it wil break at 25psi

[crnkin]

yeah if i dont baffle the sump etc...... but Theres no way id need 25psi drifting, probly run like 10-15, hey ive only ever drifted an rb20det so i have no idea how it will go

the thing is NZEFI ae86 runs 234kw atw on the exact setup i have described with no p+p, no balancing, low comp and has stock standard ht18 turbo, stock cams, 440cc injectors, stock inlet man (with 60mm throttle bodies) and all on only 20psi

Thats on lem5 as well, not a plus........

234kw atw using 440cc injectors? isnt that a bit too much power for those injectors? any other fuel mods?
what was the redline for that engine? did they start with a bluetop?
do they run it on 20psi everyday or just at events etc?

Not really.

All the "440's" I have tested at work flowed near 500cc's.
My car made 204kw atw on injectors that I flowed at 400cc.
That was on the limit though.

ask him yourself!

[Bazda]

234kw at the wheels....and a 11.97@113mph...
Ok his time is like 1 sec better than mine nearly but his trap speed is 1mph faster...to me thats not a 234kw car if you put it on any other dyno.
