Performance Stroker Kit (91.2mm)
Includes: Crank, Rods, Pistons, Rings, Main & Rod Bearings
- Our Stroker Kit consists of a meticulous off set ground crank hardened
to 91.2mm (done here in our own crank shop)
- Chrome Moly H-Beam (up to 600HP), or Billet rods to 900 HP
- Custom Length
- Standard weight pistons for the Turbo’s with upgraded pins and coating
are available. Normally Aspirated pistons are super fly weight for
increasing RPM’s at a greater rate. As low as 268 grams (stock pistons are
- Plasma Moly Performance Race Rings provided for both turbo’s and N/A
- Performance main and rod bearings.
As the largest single supplier of Cavalier engine parts in the country,
lots of our customers have asked for a way to add additional HP
without having to change the complete motor
and spend a lot of money. After many requests to build this kit,
a combined effort with Wiseco Pistons, Pauter Machine and Molnar
Connecting Rods, and 2 years in the making, here it is!
Time to Add Brute Power Now! Our Stroker Kit is available for both normally
aspirated and turbo applications.
The existing motor has a displacement of 2189 cubic
inches with a 88mm stroke and a 89mm bore, which equals 134 cu
Our new Stroker kit has a 91.2 stroke and bores up
to 90.5 which equals 144 cu inches or 2345cc!
These kits are adaptable for street, strip, oval track and
drag racing. In addition to the extra stroke, the rod length
has been lengthened to allow for a 1.52 stroke to rod ratio.
This enables the piston to be lighter and keeps the piston
further up in the bore to relocate friction on the thrust side.
All considerations have been made to make the complete assembly
to be as light as possible to produce more HP with less
Existing motors with this additional stroke have produced
approximately 30% more torque than motors of a lesser
stroke. HP increase will depend on the total amount of
performance parts, like cams,
headers, head work, exhaust,
valve size, etc.
The intention of this kit is to allow a substantial gain in a
total HP and torque (knowing the limits of this motor and
their ability not to make very high RPMS 7500). The additional
stroke and longer rod will allow a substantial more brute
power to the motor throughout its complete max RPM ranges.
Turbo’s = 89-89.5mm
Oval Track = 90mm
Street Use = 90.5mm

I write to you tonight with so much excitement I don't know
if I'll be able to calm down and go to sleep! I tuned the timing
and fuel a little on the test car and I free'd up some more
power. I have it down in the single digits for 0-60 times and
there's still room for improvement! It ran a 9.84 with 1.2
seconds of wheel spin and it still takes nearly a second to
shift from first to second for some reason... There's always
some acceleration during those times but definitely room for
improvement. I really think I can squeeze 8 something 0-60 times
out of this bad boy as is. I believe 200hp is going to happen
soon! :) DTS2
In order to validate the additional
performance of our 2.2 stroker kits (available for ‘94-03), we have chosen
to have our testing done at an independent source. For this we have asked DTS of
Ponchatoula, LA - a long time builder and tech guru of the 2.2 engines.
(NOTE: these Dyno Graphs are to the
wheels, engine HP will be higher.)
As a Result of this Testing...
DTS has informed us that with just the
addition of our stroker kits in a bone stock ‘95 cavalier motor with a ‘98
vortech head, the increase of horsepower and torque was increased by 20%
across the board (dyno sheets will be soon provided!).
Due to the horsepower and torque expanding completely across the RPM ranges as
opposed to a stock stroke motor, an engine with this kit provides more neck
snapping forces throughout the RPM range and it’s enjoyable and impressive to
drive. With additional add-on performance from IPP such as light weight
pistons in various bores and compressions
for both N/A and Turbo applications, light weight
adjustable cam gears &
performance cylinder head, we would
expect an additional 40-60 horsepower and torque making it a gut
wrenching drive. So if you want the best ride of your life on the street,
Performance Street or oval track racing this kit is for you!!!
