930 in 1303

[Jim Hunter]

Hi,

I take the final decision to put a 930 4-spd in my 1303.
It is very hard to locate one and if we speak for the early 76-77 model years (3.0l 930 not 3.3l) with the short bellhousing is almost un-obtainable !
So I take a good use '84 long bellhousing for start :

Complete dissasembly of the trans is required due to shorten the bellhousing and the mainshaft by almost 30mm this can be avoided in a buggy or open engine bay car.After the shortening is about 2cm longer from a 915 but is wider a bit so frame horns need to mild haved to let it sit.If you fit an engine with not much HP you need to buy at least 3rd and 4nd aftermarket gears as they are waaaaay tall.Stock R&P is 9:38 but a 8:41 is available in aftermarket.
It can handle easily 550 HP in stock form !!!
This trans can only be compared with a Mendeola for strenght (935 handle 1000HP).Mechanical cluth also.

My question is did you know any to have done this conversion?

Hi,

don´t know anyone who did this conversion. But my question is, what kind of engine will you be driving? Is it necessary to work with this monster-gearbox of Porsche?
Even with the Turbo-engines of Subaru we work with the 915, and we´ve never had a breakdown yet. The 915 is still easy to get and besides easier to install than the 930. And what´s even more important is, that you have a 5th gear.

Hello,

I will be a "monster" single turbo nitrous injected rotary dynoed at 611HP...
As I will mainly use the car for drag strips R&P size gets my attention.
915 8:31 R&P lasts for about 6 passes then is scrap...
G-50 is very good too but I don't need a 5th for the passes!

I post pics the project begins !

You have Dutch relatives Jim?

Personally I don't know any more detailled info than that there is on that website. Just browse through all pages. There are some very detailled pictures.
Or you could send an email to Robert Jongen who's car it is.
