Richard_M Posted September 25, 2012 Share Posted September 25, 2012 I need to replace a gearbox on a mk3 Spit - but am looking for something a little stronger as the engine is putting out quite a lot more bhp than standard.I have access to a Vitesse 1600 3 rail box in very good condition - what are the internals of this like in comparison to standard mk3?All wisdom received and appreciated.ThanksRichard Quote Link to comment Share on other sites More sharing options...
heraldcoupe Posted September 25, 2012 Share Posted September 25, 2012 It won't fit and it's a very weak gearbox, so a loser on both counts I'm afraid,Cheers,Bill. Quote Link to comment Share on other sites More sharing options...
Elma fud Posted September 25, 2012 Share Posted September 25, 2012 ;) why not go for a type 9 conversion should cope with upto 200bhp Quote Link to comment Share on other sites More sharing options...

I'd go MKIV Spit/Toledo 'box route rather than this one...Mark Quote Link to comment Share on other sites More sharing options...

Clive Posted September 25, 2012 Share Posted September 25, 2012 Isn't the single rail internals into a 3 rail box the thing to do? or something like that. Maybe it is dolly 1850, but IIRC some special parts are required. Papworth is the chappie..... Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted September 25, 2012 Share Posted September 25, 2012 Just use the single rail box on 4 cylinder cars as the proper bellhousing exists. Only transplant into 3 rail case on Vit/GT6 as the bellhousing doesn't fit the single rail case properly.Nick Quote Link to comment Share on other sites More sharing options...
Richard_M Posted September 26, 2012 Author Share Posted September 26, 2012 Thanks all.The engine is developing circa 130hp. I currently use a standard box with close ratio 'GT6' internals, and a fine-splie input shaft, modified from an 1850. I can stick with this setup, but it's clearly a weak point at rick of failure.Type 9 is an alternative and will handle the power, as will a more expensive Supra conversion, but as I have the Vitesse mk1 box sitting around in mint condition, thought it was worth asking...Richard Quote Link to comment Share on other sites More sharing options...
Mark Hammond Posted September 26, 2012 Share Posted September 26, 2012 Vitesse MKI or 1600? They are different. MkI is 2 Litre. Either way, worth selling.....M. Quote Link to comment Share on other sites More sharing options...
