Starter motors

[BobE]

I'm going to replace the short/1.4KW starter motor on my 4 litre as it seems marginal for the job. (I'm also going to uprate the battery and the engine earths). The options are the longer 1.7KW version from TVR Parts or the heavy duty version from TVR Powers. Has anyone got real life experience of the latter compared the standard 'long' version as it's twice the price?

I fitted the 1.7KW motor from TVR parts,

and a new battery from Halfords

I've yet to double up the engine/chassis earths but what a huge difference in the speed the engine now turns over. A slightly involved job as you need to make up some spacers to re-position the rear air-box support bracket - and in my case the clutch bleed hose.You also need to modify the alternator fuse holder position on the plate that attaches to the rear of the starter motor.

Sorry to be late responding to this topic. I removed the long bolts that hold the starter motor together - being very careful not to disturb anything in the assembly and used these to hold the existing bracket in place. The latter had to be spaced off of the starter motor back plate using some washers between it and the motor as the latter has and 'embossed' face. (There is a lot of thread engagement at the end of these bolts so a small reduction caused by the washers is not significant). The solution regarding drilling more holes in the airbox is an alternative to using spacers to re-position the airbox bracket bracket.
For those who are in denial you might want to re-consider taking no action.... I now have a problem with my immobiliser not always releasing the fuel pump and starter motor circuits and I'm going to have fit a complete new system.
