CasperGTI Posted June 28, 2011 Report Share Posted June 28, 2011 ARC's were the early engine used in the polo GTi iirc. I think they are the same.John Quote Link to comment Share on other sites More sharing options...
tttttada Posted June 28, 2011 Author Report Share Posted June 28, 2011 Hi John,There seems to be opposing answers to this, someone mentioned that the Lupo's gearbox won't bolt onto the ARC's.It would be much easier for me to use this ARC block, as I could build it on a engine hanger, and simply swap with the AVY when it is completed.Tada Quote Link to comment Share on other sites More sharing options...
CasperGTI Posted June 29, 2011 Report Share Posted June 29, 2011 Ahh yes you are right there. The lupo gearbox will only fir the lupo AVY engine iirc.I was on about engine internals and pathways, where im pretty sure they are the same between ARC and AVY.John Quote Link to comment Share on other sites More sharing options...
tttttada Posted July 3, 2011 Author Report Share Posted July 3, 2011 (edited) Server was down for a few days???In that case, I guess I will have to find a salvaged AVY block somewhere.... I cannot part with the 6-speed gearbox, the shift feel and gear ratio is perfect.A little update on my readers ride thread.http://forums.clublupo.co.uk/index.php?showtopic=44255&st=160&gopid=939946entry939946 Edited July 3, 2011 by tttttada Quote Link to comment Share on other sites More sharing options...

Dogwood Posted July 17, 2011 Report Share Posted July 17, 2011 You might find the gearing of your standard box will be too long for your new engine. You'll probably have peak power at around 8200rpm and find yourself revving to 9k. You're going to be geared for about 180mph.I'm not sure if there are any shorter CWP's available anywhere for the GTI box though.There are dog boxes and sequentials available from Germany in the 085 bellhousing pattern, which is Polo GTI fitment. You also occasionally see Gemini sequentials for sale on racecarsdirect. Again 085 fitment.Server was down for a few days???In that case, I guess I will have to find a salvaged AVY block somewhere....

tttttada Posted July 22, 2011 Author Report Share Posted July 22, 2011 Back from vacation, and I must say, this thread is full of win with Dogwood chiming in You might find the gearing of your standard box will be too long for your new engine. You'll probably have peak power at around 8200rpm and find yourself revving to 9k. You're going to be geared for about 180mph.I'm not sure if there are any shorter CWP's available anywhere for the GTI box though.There are dog boxes and sequentials available from Germany in the 085 bellhousing pattern, which is Polo GTI fitment. You also occasionally see Gemini sequentials for sale on racecarsdirect. Again 085 fitment.Thanks for your input I have been closely following your thread on clubgti. Your car is a work of art and an inspiration to many.Now, about the gearing.... that is certainly a concern. But I am not sure about opting for sequentials or dog boxes just yet, as this is not a dedicated track/race car. I'd like to drive around town once in a while, which is almost impossible to do with the aforementioned gearboxes.Will definitely keep this in mind though, and I may go that route if the gearing is unbearable on the track.Thanks again.Tada Quote Link to comment Share on other sites More sharing options...
