tHe 'Z'

theres a problem with your car, theres no color, pls upload color photo lmao. nice work man, id love to see this work. im gettin ready to build a new z18et and doin research of late. will definately keep an eye on this thread

best way to sort this out is put a z18et bluebird (910) against a L20B et bluebird (910), making sure both cars are using standard parts ie (same turbos, same size injectors etc) and see who wins. i agree with the stig, fair enough im new 'here' but ive had a lot of experience with bluebirds (910's) and engines. the point i see from the stig is the z18et being the FIRST Z engine was NOT designed for anti pollution, and if i remember from my research the point of the dual spark (with the z18et) was to burn ALL the fuel in the chamber thus improving economy (as it now needs less fuel to make more power as all the fuel in there is used) without decreasing flow or power. now from where i sit, and logically this is, how does an l20b head have better flow when the air comes in one way then has to turn back on itself? isnt it quicker and better flowing to come in 1 side and out the other? another reason many l20b owners dont use z heads is because people talk them down, the parts are FAR less available and l20b's are lining garages as they are the most common engines around (besides rb's) 1 thing i also want to point out is you are using z22e, z22s, z20, z24 and z24i to compare to the l20b. get some stats on the z18et heads THEN make your comparisons. the z20, 22 and 24 here in aus are used in 4wd's only, because lets face it, they suck, they have torque but have no balls. also if the l20b head was better in design and flow wouldn't george fury have used that in his 910 bluebird at bathurst to win pole position over 5L V8 commodores, falcons and ford sierras with cosworth motors? just from that, and i may be stupid but i would say the fact nissan used the Z engine, would mean they are designed and work better? thats my 2c george fury's racehttp://www.youtube.com/watch?v=S8YWciZTv70&p=B693588F7A7042E9&playnext=1&index=55 fury overtakes 2 some more fury action i think weve all been off topic anyways, the OP made a great post/topic with stats that many people have trouble finding so hats off to him. id also like to state that the george fury bathurst bluebird took 45+psi on qualifying laps and ran 25+psi for the race. the turbo used for qualifying (3 or 5 laps in them days) was removed before the race and replaced as it was killed, naturally lol. these turbos also had no water cooling, only oil cooling but name a L series engine that can hold that amount boost.........
