Does anyone in the group have a GM 10si alternator on a GT6 ?
Is it a good fit, any alignment issues? It seems kind of iffy on the pictures from Teglers website. Would the Spitfire' amount work better?



A penny for your thoughts but everyone gives their 2 cents' worth...somebody is making a penny.

I have a gm alt. On my spit1500. It's a little bigger than stock. There's other choices that are smaller and have more power than stock.

Canely sells a 55amp.

I put this 85 amp one in my GT6 Mk1

Along with this charging cable (runs from the alternator to the top terminal of the solenoid

https://www.summitracing.com/oh/parts/pwm-1-84

I used this scheme to get rid of the stock voltage regulator (as the new alternator has one built in). I did need to fabricate a spacer for the long bolt that attaches the alternator pivot to the block

It works really well!

Jack

You can get a 14029 from Ebay, Advance, or other places. It is a direct replacement, mounts the same, wires the same, and looks very close to original. Usually about $60. If you need more amps than stock, there are plenty of alternatives.

The Denso works well and is small and light. I've heard that a Denso alternator off a Suzuki Swift is a good choice. You can find them with various pulley options. http://densoautoparts.com/alternators.aspx

I used an Delco 90 amp alternator out of a 91 Saturn. Clocked the case and it bolted in.

Jeffery,
What did you use for a pulley? The Saturn originally had a serpentine belt.

You don't really think they design and build a special alternator for each car do you?

Other than some minor differences, there are only few basic alternator types that are basically interchangeable.

Our cars need a single v-belt pulley.

It helps to be able to ask by application. Give a parts guy a list of specs and he will just give you a 'Deer in the headlights' look.

Pulleys are interchangable, but it helps if a V belt pulley is fitted in the first place.

I have used the Bosch that was used by GM on the Saturn. It can with a serpentine pulley. I simply replaced it with the pulley from the Lucas. And for a few bucks picked up the connector cable for the Bosch

The new alternator was only $50 at Cost Less Auto Parts. The guy at the counter gave me a v belt pulley for free. It just bolted right on. I think there was a slot or woodruff key or something. They also thru in a factory plug and wires. Super clean install. I modified my old external regulator as well to keep the stock look and the wires tidy.

Now that's funny. I love it.

My Bosch install was a direct plugin electrically but the upper clamp (which is also the lift ring for the engine) had to be reversed to get it to fit.
