this is a klze 323 with cams and itb's i saw a dyno sheet at one time or another 238whp!!! also look at the tach!! 10,000 rpm.

since ia have a host of mods to do to my mx3 for next years races, put in an lsd, redo suspension with k-sport coilovers, relocate battery, remove gas tank, cut out spare wheel well rivet sheetmetal over, put in 20 gal fuel cell, with stainless lines, roll cage, new brake lines goddridge, racing seats, new harnesses, 15x10 jline custom 2 piece forged wheels, hoosier 275-35-15!!! a6 race tires. for all these mods before april i have some work and spending to do. after next season after completing the research needed to do a hybrid i will build a motor at about half of what everyone says it takes. 8k is what is said to really make a bullit proof 280+ whp na klze. the head work alone is 2k, stand alone 1k, pistons, rods, and macining 1-1.5k. there is also a really neat klze intake that i found one time online completely made of stainless steel, it was housed directly oveer the ports not going over the rear valve cover and had a straight neck on it and a flage to accept like a 70mm tb. if anyone can find it let me know it was like 1000-1500. could fab one up a lot cheaper but worth a look easy 20hp with that amount of flow!!!

if you look around the site i think that the silver one was the original that i saw a while back and a lot cheaper now!!

how much was that? it said klze performance with klde, would we see those gains on a ze?

you could see those gains with an oversize tb at least 15hp

stereoking15, you seem to have things organized for your build, but I don't see 280whp possible for $8k unless you do all the work yourself. The work and parts involved to start squeezing hp after ~230hp starts to get expensive for minimal gains. Of course there would be ways to take shortcuts and still get the power, but you also affect the long-term life of the motor. I'm going the N/A route myself. In terms of what you said, ya, I could see you spending $8k in parts to make the motor pulletproof for 280whp, but the extra work in porting, machine work and balancing will be on top of that.

with the economy the way it is the project will be on hold until further notice, sucks to be american right now.
