Evening Everyone I am building up a 1.9 G60 lump to put in my Mk1 Caddy, but someone has just offered me the crank from a 1Y lump. Now I know this crank gets used in the stroker conversions and would take the engine to 2.1L, but can it be done with a G60? I am using a PG engine as the base engine and am having it bored out to 83mm to take it to a 1.9L. Will the 1Y crank fit? How much other work would be needed? Would it be worth it? Sorry about all the questions. Cheers Sammo
I would like to know this, if no one on here answers, try on dubforce as lots of g60 knowledge on there
It doesn't need G60 knowledge, it's basic. The EA827 VW block exists in various incarnations, all differing externally, but dimensionally there are 2 to 3 groups of them which are the same: height, bore potential, room for the crank. For G60 block, read DX, KR in terms of space inside. Flat backed non-bubble (2.0l) blocked. I came across someone just recently, putting a 95.5mm crank in a PG G60 block. It wasn't finished, but AFAIK, it was all ready to happen. G60 rods are 136mm normally, journal sizes are listed here for various, so then you're just down to getting a piston with the right shape to give you a compression ratio low enough for forced induction. It ultimately comes down to the pistons.
it would be easier using a tall block too, i would start with a 2E, so you get the squirters too, and then its back to pistons..
Quick question - this is the spec of my G60 engine built by RPM a few years ago: Block bored to 83mm and fitted with 83mm JE pistons Crankshaft counter balance weights lightened & assembly balanced G60 conrods balanced end over end Pistons balanced Flywheel lightened ACL bearings fitted Block decked to correct squish Head gas flowed and fitted with 36mm exhaust valves Bespoke camshaft lift .405 duration, .280 timing 30/70 70/30 Cylinder head face machined to 8.5:1 compression ratio Turbo drain to sump Unit assembled for competition use I've also got a TSR 2042cc engine which has the long throw crank in it. Can i stick this crank in the above G60 engine to up the cc? As i'm upping the size of the turbo and the above engine was built with a modified T3 in mind and less than 300bhp, i'm also thinking of changing the rods - what should i go for? Cheers, Dan.
The G60 can flow more than enough if worked properly - Click But yeah, you could actually end up going N/A if the charger doesn't pump enough air. (It has happened before) Would probably be easier to stick with a short block 2.0 as far as readily available/uprated pistons - 83.5mm 9:1 CR $629.95. Neil.
Sorry, didn't realise he'd written supercharger doesn't physically flow enough air to make going 2.1 a real performance option..
Just my thoughts but just stick to making the pg block a 1.9. It's tried and tested and with the right set up can produce around 280bhp. If u want somthing a bit diffent from the norm but want to stick with the supercharger how about a g6016v.
With such a big stroke you cant make much revs. 95.5 stroke and 7k rpm is already 22 meter per second piston speed! Also 95.5 stroke and 136mm rods would be a bad choice. My best 8v G60 engine was a 2E with 86.4 crank and 159mm rods with custom 9.5:1 pistons (block decked) 41/35mm valves custom inlet manifold with ABF throttle body (and another small throttle body for charger reroute in intercooler pipe) it did 312hp with 60mm charger pulley.
Right enough though, rod ratio is pants. 22m/s..pah, for wimps, Hows 95.5 stroke hitting 8400rpm no problems Again, for the non-believers: http://www.youtube.com/watch?v=FiBupCyOvv4 How many more times,diesel cranks will rev, proven!!
I think a max of 1900cc and a very small wheel on the chager would succeed. My engine was 1825cc 8V and with a 60mm wheel I could fill it to get a nice 296hp/330nm 8200rpm output.
Bringing this thread back from the dead I ended up selling all my VW stuff to pay off a fair old whack of debt! I am however once again looking at knocking up a fancy G60 engine. I am still dead set on using the 1Y crank, however I am still stuck on what block, rods and pistons to use. If anyone can point me in the right direction it would be very helpful
