The SVX 5 Speed
One of the most obvious things the Subaru factory forgot for the SVX was the availability of a 5 speed transmission. If the factory 4EAT automatic had proved less troublesome, a 5 speed would not be so sorely missed. The automatic is plagued with overheating problems and premature wear of the clutch packs. Many owners have replaced their transmissions three or four times. You've gotta love your SVX to do that! Following in the footsteps of at least one intrepid and possibly frustrated owner, Small Car has designed a conversion that looks and feels like the Subaru factory might have corrected their earlier mistake.
More pedals for your SVX! What a blast to have that flat six in front of a five speed. It allows you take advantage of all the potential of that boxer engine. Off the line performance is stunning!
Factory looking shifter fits nicely inside the SVX. Shifting is quick and smooth.

The five speed we use is from the Impreza, Legacy, Forester, WRX. This transmission has been proven in cars running over 300hp and 12 second quarter mile times.
Driving the 5 speed SVX is a wonderful experience. The best words I can think of are nimble and quick. The weight lost from the automatic I'm sure is significant but can't completely explain the feeling that the SVX is lighter than it actually is. Shifter, clutch and steering feel very light to the touch and the engine revs very quickly. It drives like it might be maybe 2500 lbs, lighter of course than it really is.
It's very easy to go through all five gears quickly or to wind up the engine and pull 80 MPH in third and over 100 MPH in fourth. The amazing flexibility of the 3.3L motor is evident at all times and you can skip gears up or down without the least trouble. With the 3.90 final drive and the .738 fifth, 70 MPH indicated reads 2700 RPM on the tach, very smooth and quiet but with plenty of power available for passing.
Using a Gtech Pro and with a less than extreme launch we recorded a 15.33 quarter mile time at 93 MPH.
Yes, Subaru really missed the chance to put the SVX at the top of the Sports car market !
The conversion cost is for labor only you supply the donor parts. We can supply the basic kit $349 if you don't already have it. Your old transmission is yours to keep if you wish.
Please note that there may be some parts on your SVX that are worn and may need replacing when the conversion is performed. Examples would be differential bushings and driveline center support. We may recommend replacing these parts if they are worn out.
OBD2 cars (96 and 97 SVX) may have a check engine light that will not clear because of the loss of the input from the the transmission control unit. This causes no drivability problems but may require hiding the light.
.738 fifth gear set installed - $285
