Haha! Nice, Wes. Comments like that are why I like having you guys around to post in my build threads.
Well, the past few nights I've woken up at 3am and read that "Maximum Boost" book till about 6am. Thankfully my girlfriend can sleep through a tornado.
I'm going to go with a JDM KLDE for the motor. If the ZE and DE were identical other than compression ratios I would probably still choose the DE simply to allow for more boost. Because what's the point on building a turbo car and choose a motor that will run lower boost? That's silly.
Now for the other reasons I'm going with a KLDE;
-The KLZE cam has higher overlap than the DE which isn't good with boosted cars.
-The KLZE spring retainers are known to fail at high rpm and are usually switched out with DE retainers
-The JDM KLZE is usually $200 more than a JDM KLDE and JDM KLDE (curve-neck KL's) are much more common to find than straight-neck ZE's.
But either motor will certainly work. But for my personal preference, I'm going with a safer KLDE. The rule of thumb is; higher compression = lower boost. Lower compression = higher boost.
And I know I've said this before but I'll state again, 90% of the curve-neck JDM KL motors simply have the DE specs. So if anyone is looking at buying a KLZE, don't be tricked into thinking they are the same motor just with different intake manifolds. However, there are a few curve-neck KL's that have the true ZE spec parts. Apparently during the OBD switch in 1995 Mazda built some true 10:1 200hp curve neck motors. But if you pop open most curve-neck KL's, you'll still find the KL-01 cams and lower compression pistons.
