The KLZE motor as per my original car made 197bhp and 193bhp at the wheels when dynoed.

Spec was as follows:

6 branch and stainless system
Fuel pressure regulator
KLDE ECU so VRIS switching points were not correct
63mm throttle body
Induction kit
Bigger ignition leads

I now have a chipped ecu for this to run the VRIS points correctly.


The New car spec is listed above but also has a number of unknown mods as when motor was stripped down to install the KLZE cams etc but I'm pretty sure its all ported and polished and who knows what. It was set up by Well Lane Turbo Center and has lots of dyno print outs in its 2 A4 lever arch files of documentation so it is a genuine figure stated above. There are engineering drawings for every custom part of this car. The original builder documented lots and lots of things. The VRIS points on this car are set with MSD window switches.

Ive seen somewhere that if you simply add the KLZE inlet and cams to a KLDE the best you can hope for is 10 to 15 bhp so it must have a lot of other bits fettled.


The compression of the KLZE is 10:1. The KLDE (KL03) is 9.2:1.
The HP rating for the ZE is 200hp@6500rpm. The KLDE is 164hp @ 6000rpm('93 only), 164hp @ 5600rpm ('94-97).

The torque for the ZE is 160ft/lbs @ 5000rpm (Have heard 180). The DE is 156ft/lbs@ 4000 ('93only), 160ft/lbs @ 4800 ('94-97).

The interesting thing about the ZE and DE torque # are that they are almost the same. What you don't see by looking at the numbers is that the peak torque of the ZE holds out longer.
