Starter Motor

[Richi996]

I have a 915 gearbox and starter ex my 911E 2.4 Ltr Engine . the gearbox has been bolted onto my high compression 2.8 Ltr .
Last time i ran the engine i noticed how slow it turned over .. so was wondering if anybody has used an after market high torque motor .. where value for money and quality are on par ...

Cheers Rich

Brise do a nice unit, a bit dearer than some but lovely quality and very light. I've had one on for 20k+ miles with no probs.

It might be worth ensuring your main earth is clean before parting with your cash. You should have an earth from the gearbox to the rear bulk head. Might be worth checking the main feed as well.

Kind regards

Thank you both for the feedback ... my earth connection is squeeky clean ... i think it is just my starter was fitted to a 911E so only producing 0.8 ps instead of the later more powerfull 1.5 ps . has anybody tried the Cambridge Motor sport ones .. they come in a little bit less expensive then the brise units . Otherwise i presume i can buy / use any starter up until the G50 from 1987 for my 915 box .

Cheers Richard

Richard,
I have a 915 gearbox mated to a 2.7 with raised compression. I needed a new starter motor and went for an aftermarket lightweight high torque unit. Started with an external solenoid unit and moved onto the internal geared unit when that did not work. Maybe it was bad luck but neither design worked all the time. They would jam. I reverted to a rebuilt Lucas unit in the end and so far it has worked well.
I certainly got adept at taking starters in and out. I have a modern competition loom fitted and checked the earth and connections before I started changing the starter motor.
I am told by those that should know that the Porsche does not seem to suit this type of starter motor, perhaps it is the heat in that area?
I don't want to put you off going for a high torque unit but I would have a spare standard unit available if you do go down that route.

I have had a Brize for 3 years on my 3.2 in the racer, no probs at all. I needed weight saving and compact package.
On my 911T hotrod with 915/3.2 the starter was sluggish (original starter) but fresh batteries has made it 2 x faster....

Thanks for the feedback .. just noticed Jerry that you are in the Warwickshire area .. will send you a PM .. never know we could be neighbours
I have just finished installing my front mounted oil cooler and the 2 battery boxes have now each excepted a 4 inch venting duct ... so the only option is to fit a battery in the smugglers box ....... this means i will have to go down the HT starter option ... looking on the Pelican site a few people have installed the cambridge one with no issues ... i also met them at a classic car show and the quality looked very nice .. what would life be without decisons and trying to convince the misses indoors that the expense is justified

I have used a 3.2ltr 1.5hp starter on my 2.4T,-fantastic!! fits straight on with no issues, fairly easy to come by s/h and a lot cheaper than after market hi-torque starters! (trust in Dr Porsche)

Neil Bainbridge was talking to me the other day about hi-torque starters ... might be worth giving him a call

Thanks the reply ... i think i will go the Mr Porsche way and get a 1.5 hp starter .... just seems to be a lot of negative issues regarding these high torque motors and would i'd rather use the money for better upgrades .. like a full kit of Superpro bushes
