The HT Starters I believe fit from a Cmry.. If you are serious about weight, take out all the seats, carpets, panels, etc... You can get an S4 down to 2800lbs like Kibort's car.

Actually, Recaro SPG's in place of the stockers is not a bad way to go to save some weight..

Those Front Seats are heavy..!

I think the starter was a savings of only 6 lbs or so.

for those trying to save weight in a street car, those seats are pigs. lots of nice seats out there at 25lbs a piece for street use. stock are around 55lbs.
bumpers are about 25lbs each (ave)

No Mark, that is the excitation rpm, after that it charges all the time

Bosch starters are notorious for being picky about the voltage and current requirements. I've seen them get a bit hot (a few years into a rebuild) and not start a car that has ALMOST enough volts, but not quite.

I needed a starter for the 89 anyway.

I have one issue with my lightweight starter and lightweight battery. When it sits for a week or so, it does start the Holbert S4 fine, but after a 15min drive and a 30min sit, i go to start it again and there is just enough voltage, current to start the starter, but the engine doesnt kick over. so, I push start it in 2nd gear and its an easy start. later, fully charge the battery and it starts fine under the same circumstances. seems that the S4 computer is very fickle about voltage, even when there is enough to run the starter! Put it this way, if the speed of the starter was like this with my old 84, it would start with no problem. However, the S4 seems to be more voltage dependant. (as far as computer)
comments??

Yes, the S4 ecu requires about 10.8 volts to kick over. AND once everything heats up, up goes the resistence too

Geez, doesn't seem that cost-effective. Don't want to spend hundreds to save 6 lbs. Bummer.

Guess I should look ino lighter seats.. but I like the seats that are in there!

CMW

Ahhh,

and the great quandry continues...

Thaddeus

I am going to shave 200 lbs off the car. And no one will be the wiser. Wait and see.

You will become very familiar with the Law of diminishing returns.......Mark A only runs 1/2 of the fender bolts !!

Thaddeus

Wait and see.

I think thats the answer.. i bet the battery is in OK shape, but weakening. after the 100% start , even when the battery voltage has dropped from its nominal 12.7 to about 12.3 or so, it starts. (with a pretty big voltage drop on start up) then, as it gets hot for my short speed run, and turn it off, the re-start with higher losses do to increased resistance, is dropping the voltage under the 10.8v as you say. thats the issue with those smaller batteries, they are a little more fickle, especially after a couple of seasons.

I got that starter from ebay today. The guy is in riverside, so it was one day delivery. Very very small, but its obviously geared for the bigger engine sizes. The flange fits perfectly in the hole for the S4 starter.

I may get another one for ther 78. I was usuing a borrowed starter - I fried mine with a shorted battery cable melting against the headers.

I'll see how much a rebuilt starter is compared to this one.

I picked up the lightweight starter for street use, and i think its great. YEah, it does sound a little higher, but it is by no means bad. In fact, I kinda like it for a change.

The design of the lightweight starter is IMHO BETTER than the bosch unit. It took me over an hour to get the bosch starter off because of those damned alan bolts. I just end up unbolting the sway bars. With the new starter, I can get it out in about 15 mins since it is smaller and there is more room to work. It also places the power/signal wires in a much easier-to-access location so that you don't need to remove the starter to check the wires (ok.. not a big deal for most people, but i have interesting electrical problems with my car...)

anyways... given the option for a new bosch starter and new high-tq starter for the same price and same weight, i'd buy the high-tq starter (assuming it doesn't stop working on my within the next couple years).

Brendan,

Can you weigh the stock and mini?

I would have bought one of the minis, if I hadn't just bought a rebuilt, just two months ago.

OT: Your new avatar shows you must have got some 'bling' in the mail. Fits OK?
