914-6 conversions
Posted: Sun Apr 15, 2007 9:44 am
Was wondering the other day how many people are building / have built 914-6's around 4 cylinder shells. Thought that it would be interesting to see a) what people have done, b)how they have gone about it, c) what problems they have encountered and d) where they got the various bits from.
I bought my '14 from a chap in Holland where it had been sat in a warehouse for years after a rather large frontal accident - after agreeing to buy it in October 1998, eventually picked it up in September 99. The car had apparently been used for some form of racing - not really sure whether it had or not but the remains of the shell was cheap! After a couple of years sat under a cover, we started repairing the damage to the front. The shell repair was pretty quick (by the standards of the build up!) and the main things that have been done are to use f/g bonnet, boot, front wings, front and rear bumpers and arches. The bonnet, bootlid and bumpers all came from Barrie Martin who I would wholly recommend to anyone going down this route. The shell has been repainted in signal orange - as per the works cars.
Once the shell was built, we fitted a safety devices cage - which I have to say fitted amazingly well.
Moving on the rest of the car, fitted a mix of bits for the front suspension - but in the main it is 911 with the later type of a/roll bar but using 3.2 Carrera struts, 930 hubs, discs and calipers.
Rear suspension was a bit more involved given the spacing of the original calipers is different. After a bit of tinkering we ended up welding brackets to the trailing arm to take the 930 rear brake calipers and discs. Handbrake wise, we have gone hydraulic - which seems to be OK.
Engine - I bought this from Colin Belton at ninemeister where it had been fitted to a 3.0RS rep that he had there. Not sure of the exact internals but it is a 2.7 7R case, running on Weber's that at the time (we checked on the rolling road) 220 hp.
Gearbox - now here is the really marginal point - have a sideshifter gearbox in the car now - depending on who you speak to it may / may not be sufficient. Am working on the philosophy that if it breaks it wasn't strong enough and we will have to worry about what to do then. Michael Witter at Mittelmotor said that he felt it should be OK....
Oil system - here is where I definitely made the most expensive / time consuming mistake. Initially used a fabricated oil tank that sat in the space where the fuel tank originally went along with a reduced size fuel tank. However, I was never happy with the way that it was plumbed up, so decided to revert back to the standard set up. Bought as many of the parts that are now currently available (still haven't told the wife how expensive they were!) and have been slowly accumulating the rest. Have found Earls at Silverstone very helpful for some of the various fittings. I have a separate oil cooler to sit up front which Barrie Martin sourced for me but am going to run without this initially whilst it is all being bedded in.
Wheels - have gone for 7 and 8 inch 15 Fuchs - yes they will fit over 930 calipers but it is very close!
Interior - simply a pair of Sparco Ultra seats (amazingly light) and five point harnesses.
Would be very interested in hearing what others of you are doing / have done.
