1127GSXR1991 Posted July 25, 2016 Author Share Posted July 25, 2016 Looking to rebuild the block, currently a 1127cc. I was told to take it to a 1371cc. Will make a monster of a bike. Any other idea's? Quote Link to comment
Gixer1460 Posted July 25, 2016 Share Posted July 25, 2016 You may struggle to find a 'Gorilla' block to take liners that big - APE haven't made them for probably 10+ years. Plus without extra finnage on the block it'll run bloody hot as a streetbike! Personally i'd stick at 80mm turbo pistons and a nice punchy draw through BB turbo with EFI and single throttle body! 1 Quote Link to comment
Havoc Posted July 25, 2016 Share Posted July 25, 2016 My 1340 with 40mm Lectrons and nitrous on C16 went really nicely, for a bit..... Quote Link to comment

Someone with some engineering skills/ contacts should arrange a group deal and commission a batch of 10 Quote Link to comment
Fula28 Posted July 25, 2016 Share Posted July 25, 2016 They are about as I'm sure most know! Just ask, Stuart warpspeed Quote Link to comment
Paulm Posted July 25, 2016 Share Posted July 25, 2016 Try Dave Dunlop,for a block and liners. Quote Link to comment
cregnybaa Posted July 25, 2016 Share Posted July 25, 2016 I have a 83 or 84mm block and 3 pistons will check size in the morning, the cylinder is aftermarket I think the pistons are je I don't think I am ever going to use them so may sell if interested. Quote Link to comment

Just ask, Stuart warpspeed Yes - Warpspeed = 2nd to none machining but would you really want to run a dry block on the street? This is a streetbike (from the piccies?) 1 Quote Link to comment
Reinhoud Posted July 26, 2016 Share Posted July 26, 2016 Wrap a garden hose around the block and connect that to the cooling system. Quote Link to comment
Fula28 Posted July 26, 2016 Share Posted July 26, 2016 Agreed say what now!? 1460. Was just trying to show there available ! Street finned are availed too .i just don't have a piccy. Quote Link to comment
Reinhoud Posted July 26, 2016 Share Posted July 26, 2016 Are the studs that far apart, and is there that much material around the crankcase where the liners go in, that you can put such big cylinders on on those engines? My GS1000 has 8.25mm bigger pistons, and that's absolutely the max. Quote Link to comment

Finned blocks will certainly help but they don't half look weird when compared to a std GSXR block - need surface area which is in short supply unless you want it to look aircooled!

colinworth79 Posted July 26, 2016 Share Posted July 26, 2016 found this block on that site a year ago . Its not going to be cheap . Crankcases opening out to except the liners , stronger rods , ported head , cams , head and case studs and pistons . On top of that new shells , bearings , seals all adds up . This engine is going to be low comp on an 85mm bore . Easy £4k can be put into something like this . 1 Quote Link to comment
colinworth79 Posted July 26, 2016 Share Posted July 26, 2016 the bike in the pic looks nice and clean if it was mine rebuild the lump bore the block to 81mm with forged low comp pistons then blow through turbo kit. Easy 200 hp and loads of torque . Quote Link to comment
