klde and klze

Since most folks can find a klde cheaper than a klze is there any way to get the parts to turn a klde into a klze. What are the differences between the klde and klze. Both are 2.5L. klde 160hp, klze 190hp. Are the heads , block, intake manifold the same. Maybe swapping cams, pistons and computer will get a klde to put out klze numbers. Any input would be helpful.

Buying all of the parts to make a DE into a ZE would end up making it more expensive than just buying a ZE in the first place, but here are the basic differences:

Intake manifold (larger runners and different VRIS setup - about $1,000 U.S. for a new one from Corksport)
Heads (different porting to match with manifold)
Cams (more aggressive profile - about $700 U.S.)
Pistons (higher compression - about $300 U.S.)
ECU
VAF

According to Interprep's dyno tests:

ZE intake manifold gains about 10 hp and loses 2 lb.ft. of torque.
ZE cams alone gain about 9 hp and gain 2 lb.ft. of torque
ZE cams and manifold together gain about 15 hp and lose 2 lb.ft. of torque

You could expect a bump in compression of nearly a full point from the pistons to give you maybe 5-10 hp and a comparable amount of torque as well - the remaining 5-10 hp would be from the ECU tuning.

If you are the type of person who would tear down and rebuild the ZE before putting it in anyway, then if you rebuild a DE with ZE parts, the best bang for the buck would be to get just the cams and pistons. They'll get you from 10-20 hp, and you'll have 5-10 lb.ft. more torque than a ZE. That will still run you $1,000 U.S. for parts on top of the DE motor itself though...

Where the hell you buying your parts? Tiffany's?

Try - used KLZE pistons $60+shipping. Used heads - $250. Used cams - $225. Used intake manifold - $200.

Those prices are for NEW components from Corksport, not used...jackass!

Seriously, though, if I were rebuilding, I would not be rebuilding with used components - I'd be rebuilding to replace used components in the first place...

In response to babyblue's post below, if you read my earlier post, I would not get the intake manifold - just the cams and pistons. I agree, a new intake manifold rather than used would be pointless - it's not really subjected to any kind of wear, unlike the pistons and cams.

you'll learn that corksport sells twice the price as other places.
who would need a NEW intake manifold
