Yes, eventually everyone gives their Opel the finger!
Thanks. the total cost was around $150.Very nice Gary, I love it :yup: What did it cost?
Very nice and done super cheap!Thanks. the total cost was around $150.
$50 for the Saturn steering column. $60 for the controller. $10 for a heat sink for the relocated EPS module. $30 for a shaft coupling.
The EPS motor fits nicely under the dash at about the 10:00 position. I relocated the EPS Module to the firewall just above the fuse box and added a heat sink to dissipate any heat.
The most difficult part was keeping everything in alignment when welding the shaft to the coupling.
I know what you are talking about. First gear is so short at both 4-speed and Getrag 5-speed transmission that it becomes almost unusable if you have higher power engine. That is the reason why I kept 3.44 ratio in my differential. I still last only 2-3 seconds in the first gear before possibly over revving the engine.I might look into changing out the rear gear ratio. It has 3.73's now and I'm in first for about 3 seconds.
Don't know why but I figured you had a 5 speed getrag in there...... So what tranny are you running behind that mighty 6 cylinder beauty?The wagon has a Volvo 240 rear end which is a Dana 30 with 3.73 gearing and a G80 locker. That combo with my 195x60x14 tires puts the RPM's at 3,541 when going 65 mph. I'd like to drop that down and decrease the total first gear ratio (14.2:1) down.
Max torque at 3,600 RPM
Max HP at 6,000 RPM
A ratio of 3.07 would bring the RPM's in 4th gear at 65 down to 2,915 and the first gear total ratio to 11.7:1
Jeeps use a Dana 30 in their front diff and the 3.07's are readily available.
The problem I'm running into is the Volvo Dana 30 uses a different carrier for ratios under 3.73. And I haven't been able to find info if the 3.07 ring gear will work with the G80 carrier. I can get a Jeep carrier and gears for ~$150 and if I go that route I may lose the locker if the gears don't fit.
Another option would be to go to larger diameter tires. 225x70x14's will increase the diameter by 3 inches which drops the 65 mph RPM's down to 3,800. The problem with that option would be possible wheel well clearance and ride height. Ride height can somewhat be set by adjusting the coilovers.
Time for a beer!
