I alone know this motor is the sheet because kyle (kef) gave me the SAE docs on it. Lets hear what everyone else thinks about it. HERE.

Does well enough for me until I get sick of it haha. Pete, you certainly know what your talking about. Check your pm's.

PS. I though kef was breaking my balls about my motor at the meet the other night, but maybe I misunderstood his tone.

honda copied VVTL-i and called it i-VTEC

[teh DIRT]

haha. i wish i could find that tech document. Id post it up....ill ask kyle when i get a chance.

yea, VVTL-i is pretty decent in my small motor. When the engine hits lift it almost feels like a 25shot of N2O haha. You can feel the car jerk forward and rev harder.

[teh DIRT]

your sig rocks

[DoubleOughtCel]

haha, thanks.

its actually a 50hp increase depending on year....my last car was a matrix xrs and i hit lift at 6300 rpm to 8450 redline....you technically only have 130hp until then in order to save on fuel.....my trix was running 14's in a big heavy wagon...the motor itself is a work of art....why else would lotus have to nearly beg toyota for the motor?...

it's a 2000 GT-S, however its an automatic .

Now, they need to combine it with someone else's technology.

Ford uses(used?) a set of plate valves in their intake manifold to alter the path of the air depending on RPM - long runners opened for low end, both open through most of the RPM band, and the short runners open only at high-top end. They called it VRIS (Variable Resonanse Intake System) or IMRC's (Intake manifold runner control) depending on year/model.

Notably are the 2.5L KL (mazda/ford) motor and the 3.8L mustang motor from 99-04

The only gripe I have about the car is the fact that it had no bottom end. It seriously is a snail until the top end of 2nd. Any suggestions?

[teh DIRT]

that could have a little bit to do with gearing. Intake runners have a lot to do with top end vs. low end power.

Toyota has been using that technology for a while now. It was once known as TVIS in the 80's (Toyota Variable Induction System), then in the 90's it was updated and called ACIS (Acoustic Controlled Induction System) -- both 2 stage "variable" intake runner systems. The old 3S-GE engine in the Celica GTS (86-89) had the TVIS system.

iirc, the MKI MR2 4A-GE engine also had the TVIS system
