As requested,,,,
My name is David Taylor, I'm hopeless race addict from Portland Or...
My hobbies are hunting, Racing, Playing with any motor toy...
I have a 1994 Jeep Wrangle with 200K miles on it. Bought new by me,
has air lockers, 44 rear, Warn upgraded front end with their axles and hubs.
And probably the most important item a fairly well built 2.5 liter engine.
About a year and a half ago I scratched up the money and had my 2.5 totally rebuilt.
The engine Builder is Jeff Rayburn in Oregon City Oregon. He bored the engine over .040,
I purchased a hesco cam and lifter and chain kit. He fully ballanced and blueprinted the
engine, multi angle valve job, relieved the guides, Hyperutectic (SP?) pistons. massaged
the whole block. High Pressure Oil pump(Not High Volume), I added a 62mm throttle body
and a 3/4 in spacer. After a LOT of fiddling I got the thing running right, being bitten
twice in a month with a bad TPS and IAC that I had bought new when I did the motor. :(
The engine pulls from about 2500 to about 7000 without the throttle spacer and 1700 to
6000 with the spacer. Its still a 4 banger but it has great torque and drive-ability compared
to original.
I met him through my hobby of
racing cars. I had a road racing license for several years, drove a Mazda RX3 with a friend of mine
at PIR international raceway in Portland Oregon. To support my habit I worked a deal
with another friend of mine who owns Competition Motorsports here in Portland,
I would maintain his rental race cars in exchange for seat time.
I helped Maintain a 1984 200SX Turbo that holds track records at 4 tracks,
a set of rental race cars, nissan Sentra's 3 of them... Great little school cars.
I've helped work on dozens of cars at PIR as well as Rons Dirt cars, a Wingless
Sprint car (smallblock chev 600+ hp in a 1000 lb car!) and a Midget with a Cosworth 4
cylinder that makes up for its small displacement with a lot of rpm's. Jeff built the
engines for all these cars.
So I've spent a fair amount of time since 1999 working fiddling and wasting time on race cars... :)
I also was a member of the Oregon State Trail committee from 1994 to 1997.
I helped GPS map a lot of the trails in the Tillamook forest here in Oregon...
I think I've known Jeff Yokomura virtually over the Internet since about
1993? Jeff how long? and I think we met a couple times what about 10 years
or so ago? He thought I ought-a join and share my pain of trying to torture more
power out of possibly the worst engine management system ever built for a
production vehicle. The original MPFI 2.5/
Well wasted enough electrons....
