Gixer1460 Posted August 22, 2015 Share Posted August 22, 2015 Just out of interest do the 1052 rods have 20mm or 18mm pins - think I know answer but asking anyway? Quote Link to comment

Phill106 Posted August 22, 2015 Share Posted August 22, 2015 They will sit 1mm down from deck if you use 1052 rods on 1127 Crank.... Vizman I know 2/5th off #uckall...........But I,ve never been afraid to join bits together to find out if it will work............. does anyone know how far below deck will they sit with 1127cc crank and rods? I like it duck, your a man after my own heart haha Quote Link to comment

Sorry to hijack thread but this is all good info to know for my build haha also so does anyone know the standard 1127 rod and slug to deck measurement?

Duckndive Posted August 23, 2015 Share Posted August 23, 2015 can you remember this base gasket thickness from this? I used a stock Suzuki Blandit 1157 Base gasket.....And having just measured 3 used "GSXR" ones 1 from a 1052 motor = 0.25mm 1 from a 1127 motor =0.25mm1 from a 1127 motor =0.40mm.......

Jaydee Posted August 23, 2015 Share Posted August 23, 2015 1052 & 1127 Rods are the same ..Crank stroke is different .. I thought 1052 were longer, 117.4mm and 1127 are 117mm. ? 1 Quote Link to comment

kokolis Posted August 23, 2015 Share Posted August 23, 2015 Crank stroke on the 1052 is half mm shorter than on the 1127 Quote Link to comment

McLean Racing Posted August 25, 2015 Share Posted August 25, 2015 Im running 1052 spec carrillos in my 1127(1216) and have absolute 0 deck height with a stock base gasket installed Quote Link to comment
Phill106 Posted August 25, 2015 Share Posted August 25, 2015 So what deck high are we aiming for? For N/a and turbo? Quote Link to comment
McLean Racing Posted August 25, 2015 Share Posted August 25, 2015 So what deck high are we aiming for? For N/a and turbo?Depends on what compression u want to aim for, what pistons ur using etc. At 0 deck height, with 12:1 pistons and my head combo i was at 14.2:1 compression. With my new head it went up to around 15.5 so i have to reduce my deck height to get the compression back down a bit Quote Link to comment
Phill106 Posted August 25, 2015 Share Posted August 25, 2015 This is where I start to get lost.My plan is to use mostly standard gsxr 1127 lump (head, crank, cons) and rebored to 1216 with busa Pistons in and then add a turbo. I do have a set of gen 1 busa rods that came with the gen 2 Pistons (I know right) if that will help but I'm pretty sure they are longer. Also before anyone jumps on me I know gen 2 Pistons have smaller pins but that's beside the point. Anyway I have no idea how I work out comp ratios and in turn how far below deck I need to be. I did try google but its still quite confusing working with formula. Any help? Quote Link to comment
McLean Racing Posted August 25, 2015 Share Posted August 25, 2015 1127 rods are 117mmBusa rods are 119.5mmDoing some basic calcs off the top of my head, at 0 deck itll be around 11.2:10.5mm below deck around 10.2:11mm below deck 9.7:1 Now thats not gospel, thats based on guestimates as im not a turbo guy but thats baseing it on some measurements ive got writen down from previous engines ive built. Hope this helps 1 Quote Link to comment

McLean Racing Posted August 26, 2015 Share Posted August 26, 2015 Because you combustion chamber CC number is -304cc which will in effect give u half of fuck all lolIf its a stock 1127 with stock valves, the combustion chamber is around 23ccAlso remember that that calculator doesnt take into consideration the head gasket thickness, which can be anywere between 0.5mm to 1.2mm depending on what gasket u useSo even putting in the correct cc value in that calc will give u the wrong reading Quote Link to comment
McLean Racing Posted August 26, 2015 Share Posted August 26, 2015 What head gasket do u plan to use? Cometic MLS or copper? Quote Link to comment
