Reliability..........
Still wouldn't stop me from owning one though
I'm just far more knowledgable when it comes to the Non rotary engines. That's all. Mostly because I got involved in them due to my car.
For example, embedded nder the hood of my car is the Mazda 2.5 L V6 KLZE.
Stock would be the 2.5L V6 KL03
The ZE was availavle in J spec Mazda MX6 LSs, which are mechanically identical to Probe GTs in most ways.
The differences between the 2 engines are the Ze has.....
Higher compression 10:1
Better flowing heads and Intake Manifold
More agressive cams
This creates a 200 hp engine instead of the 164 hp engine. The power band has also shifted higher into the RPM range, along with a much nicer torque curve.
From there you find even higher compression pistons. (Cuz Lord, knows 10:1 wasn't nearly good enough.)
The you have the cams reground
Shim the oil pump as cylinder 6 has oil starvation issues
Port the heads
Port the IM
Add a 67mm TB
upgraded fuel rails/injectors/pump
Then we start adding bolt on stuff
PRM CAI
Hot Shot gen IV headers
Jeff Jeske Testpipe
Custum Stainless exhaust from there back (2.75")
Unorhodox UD Pulley
VRTuner, (To get the VRIS points in the IM correct)
Then a few guages to watch stuff
Autometer A/F with switch to switch from the front bank to the rear (The Ze likes to lean out
)
Autometer Oil pressure, ( Fucking #6)
Autometer Fuel Pressure
Autometer EGT
Autometer Voltage (Stereo can take it's toll)
Autometer Tach (Mine's horribly innacurate)
Let's not even get into tires, suspension, etc
All this equates to driving in something that's loud as fuck, gives the feel of a fighter jet cockpit, and that has caught a V8 or 2 by suprise.
Honesly I would be happier with a B6T engine or F2T, but I have what I have.
