Klze & uk spec 2.5



  • IIRC

    KLDE 164/5hp 160ftlb
    kl01 cams (less aggressive)
    kl01 heads (poorer flow)
    Dished Pistons (lower compression - higher safe boost)
    Stronger valve springs and retainers

    KLZE (straight neck "true" klze) 199hp 165lbft
    kl31 cams (more aggressive, peak higher)
    kl31 or kl31 1a1 heads (fast flowing)
    Weaker intake springs and retainers, but larger HLAs & valves on intake
    Flat pistons (higher compression - lower safe boost limit)

    DEs arent a bad thing! Infact they are the most popular kseries to boost, due to lower compression. But for NA - KLZE FTW :D Though you can boost the ZE and make more power per less PSI of course :twisted:



  • so the cams, heads, ECU and pistons are the only difference between the DE and ZE?

    hmmmm….....



  • yea that's all lol

    well that and the intakes/throttle bodies…



  • so if i buy a klde and change evryting except springs and retainers ill have a better engine which i could run higher boost on??

    would it work?



  • yea it would work, it's becoming more common for people to build DE/ZE hybrids - DE bottom end, ZE heads and cams with DE springs, and ZE intake.

    This set up is supposed to be good for 10psi and a bit over with stock internals. KLZE would be 5/6 psi before things start going wrong (unless it's perfectly tuned).

    Having said that it I'm not sure how easy it would be to get hold of all those parts to mod a DE. Also, a klze on 6psi is going to be pretty nuts - 300whp+ on a FWD car… Either engine has plenty of power to be had, but the DE probably has a higher stock internal maximum. IF you're after crazy power you may rebuild your bottom end with a HP kit - forged internals and all that.

    have a look here and see which setups are making the most power:

  • I struggle to put the power down in a midly tuned ZE, in the wet its a night mare, 60 mph cruising in 3rd drop the throttle and light the wheels up…



  • get some beter tyrers



  • better than toyo proxys ?



  • I loved my Toyo Proxes T1-R :( Then along came a big cube of steel and exploded them with my alloys :(

    Get a megasquirt in with traction control :wink:



  • beter grip with good year egal f1s i fined and there cheeper
    very good in the wet

    i have a full millenia engine people usuly just go for the inlet
    but the millenia is a standerd hybreed with ze pistons and de heads
    puts out 190 bhp they come in Xedos 9



  • Been thinking about getting a megasquirt…

    But i do enjoy overtaking saxos in second on full throttle and just smoking past em....
    :twisted:



  • Traction controll is overated ;)
