Im planning on building a 600|PLS|hp engine but would like some idea's on engine component's that i can use ie: pistons, rods and cranks. Also any ways of strengthening the block. I have taken care of the turbo, head, cams and intake manifold including fuel system, i just need some tips on building a bullet-proof bottom end.

THANK FOR YOUR HELP

fatevo,
Block won't require strengthening . Prorbably any of the forged pistons on the market will take the boost required 4 600bhp , same goes 4 rods , but if u want the utter best rod's just 4 the pose factor go 4 Pankl titanium. Go 4 a billet crank.
Head , rod and main bearing bolts shud b up graded 2 ARP. Probably a good idea 2 go 4 race bearing shells 2.
U will need cooling upgrades on the intercooler and oil cooler and radiator 2.
The main secret 2 a bomb proof bottom end is blueprinting , balancing and painstaking assembly because if anything is not running with perfect clearances or tolerances with that kind of force behind it , it's bi bi baby :(

The main thing you will need is a very large wallet.

Keep us informed.

600|PLS|hp, scary.

Hi Fatevo!

The JUN internals should do the job, get their stroker kit I would say, easier tahn getting pistons from here, rods from there, etc.

I heard but cannot confirm that JUN also make 2,5l conversions with a special bottom end, maybe contact them to find out what they've got.

2.5l would give you some serious torque.

2.5 would give you some serious over heating problems....

Prospeed are doing a 600hp engine, and Norris designs are doing a 580hp one - both based on the Jun 2.2 kit.

scoobkilla,

not saying your wrong but why? Standard evo seems well cooled. with bigger oil cooler and maybe a recored rad whats the problem? Or are you thinking about in the block?

Claudius, presumably the 2.5l is obtained from a 86mm bore (any larger and the cylinder walls would be too thin) which would mean 1 stroke of 107mm. This is starting to get pretty long stroke which will give some nasty vibration problems like the old 1600 minis. OK for rally use but impractical for the road.
