after bore do i need to upgrade...

[Anonymous]

Hey guys ive been working all week and last and im going to upt all that money into the motor on my xf i want to do a large bore something like 50thour cause i plan to install 600cc injectors so that would help with more fuel and air consumption for power but i want to know if i bore the motor do i have to change the crankshaft or con rods

What size bore do you guys recommend for full rebuild ACL(what ever size piston & rings required for bore) with 600cc injectors (stock 185cc from what ive herd) and larger fuel up to power the injecotrs, pacemaker headers and lukey exhaust system, 4 speed single rail, and small drag cam or something like that also im planing to install a supercharge on it after all the other gear in installed get a second hand one off ebay with like 22psi boost.

also i know i know ill need a new computer shit box to run it lol darn stupid computers why can't they just upgrade the data in the original one

Thx jason

Heres some help, if your running that much boost dont worry about extra capacity, it wont be needed, but bore thickness will be.
SO measure up your bores if there 3.68 inches then their standard, check with your selected piston manufacturer to see what oversizes are available then use the smallest OS that will give you a new bore surface, 0.5mm would be nice, if that will work.
Surface finish of the bore is also important and is best left to a skill shop with a good machine like a Sunnen.

yer i know ill proberly need a bit of thickness but i need the little bit more room for all the air and fuel to fit into yo with 650 or 600cc injectors shooting away and a supercharger ramming the air into the motor i think any room you can get is good lol

MAN.. HAVE you gone and spoken to a machine shop yet.... THe mods you are talking about are MEGGA costly... I doubt you could even supercharge an Xf injected motor for under 5k... thats without a re-build or computer mods which are needed..
650 cc injectors ...... why are you so dead set on them.. FACTORY injectors are good enuf for 150 RWKW..
The bigger injectors wont make youre car produce 1 hp more of power
