should i do a basic turbo kit (2500-tkt) or kl-ze(2200-corksport)???? I love turbos and blowoff valves and the prices are about the same. especially when you factor the install of an entire engine. the turbo would net more power, more expandability, less reliability. gimme feed back guys... thanx

p.s.- anyone know a cheaper place to get a klze? some have said 1400. where? corksport USED to sell it for 1800. now its 2200.

thanx

Check out http://www.usedengines.com that's where I'm getting mine it's $1400.
I bought mine from there as well for the same price.

If you have the funds, go with the turbo. You will be able to get more hp this way than with the KLZE. But, if you are really rich, get both.

I want to get both. Cuz I want to get a new engine anyways. Does anyone know how much the stock engine costs. cuz if it's cehaper than the klze, I'll jsut forget that and get the stock with the turbo. But if they run the same, then I'll get the klze with the turbo.

There's going to be a law of diminishing returns that needs to be considered when deciding whether or not to go turbo KL03 or turbo KLZE.

A KL03 with a blower can safely produce something close to 230HP at the wheels when running 7-9PSI, assuming the engine is sound mechanically. With a 9.2:1 compression ratio, the engine is fairly happy with boost levels this high. The ZE, with something like 10:1, may not like that much boost and, because boost may have to be moderated, its output may suffer because of it.

I've not yet seen dyno plots of a KLZE running a turbo but I suspect it's probably not putting an additional 35HP, over and above a boosted KL03, to the ground as safely as the KL03 is producing its output. The higher static compression in the ZE means it has a higher propensity to suffer detonation, which will ultimately limit the amount of boost you can run before hurting stuff.

Also, while the ZE has constructional differences from the 03 but they are limited, in the reciprocating assembly at least, to different pistons (for increased compression). AFAIK, the ZE uses the same skinny connecting rods and the pistons are still cast (someone correct me if I'm wrong). Cast pistons are not ideal for boosted apps and with compression that high, there's a very real chance of breakage.

So despite the fact that the ZE is the "performance" engine of the KL series, it doesn't automatically follow that it will make that much more power when boosted, reliably, over a boosted KL03. And it also doesn't mean the engine can be boosted to 15PSI out of the box.

If it were me, I'd stick with the KL03, put a turbo on it and drive it sanely while I put the $2200++ a ZE would have cost toward the purchase of "real" turbo innards for the 03: steel aftermarket rods, forged slugs, cylinder head O-rings etc. Oh yes...and an LSD :D

Does anyone know about the reliability of the usedengines website??
I bought my motor from them over a year ago, they come with a six month waranty. After the first month, I blew a head gasket. They paid for shipig of my old one and sent me a new one. The only thing I had to pay for was removal and instalation.
