Who gave you that info ?? Tomei, Jun cranks are not 4G64 cranks. They are made from forged billet stock and are drop in with the proper cylinder work.

 

nah..rc developments 930hp......
dont forget them

 

just out of curiousity- when you say forged billet stock, do you mean that they're made from the ground up as a forged cam or that they're just a forged 4G63 cam?

 

Yep have watched them mill their own cranks/cams/pistons in the shops.

 

value,

so essentially, a JUN 2.2 built 4G63 is a fortified engine that i'd never have to worry about?

can i get up as high as 8000rpm without any worries?

 

I would consider upgrades to your valve springs and retainers.

 

RC is 930 crank HP. We're shooting for over 800whp.

 

well if i was spending that much on a bulletproof bottom end i would definitely spend the money on 272s, valves, valve guides, arp bolts and studs, and titanium retainers and springs

block would be balanced and blueprinted & head would be ported.

 

Just to add in.. not to steal the thread.. we also have 2.3 stroker kits available.. we have sold many kits, even in rally cars in Europe- EVO 6, 7 and 8s. No reliability issues so far. we have them listed on the website. Actually a customers 03 will be dynoed this upcoming week. SBR 2.3 Block, SBR stage 6 head, HKS cams, GT35R, AEM EMS, SP coil on plug and alot more.. we will post pics and dyno numbers next week..

9000rpm+

 

blowing your tranny

 

wow, thats incredible. i think i'd keep it safe and set my rev limiter at 8500.


doubtful, not with a TRE-SPEC built transmission.

 

OK, I am officially asking (for those who might give Slowboy crap about jumping in), what mods need to be made to install your stroker kit? Notching the block, etc. What size pistons? OE bore requiring a hone to install, or over? Are they available in OE or higher compression (cause I'm always "outside the box")?

 

Yes you need to clearance the Bottom of the cylinder walls.. Not as much for the eagle rods as the manley due to the larger rod size.. Pistons come in std, .020, .040, .060 .. If you choose std bore, The pistons are designed to have no boring/honing required and have around .004 piston-wall clearance. The std compression is 8.8:1, but a custom piston is available in our stage 3 kits which you can select the comp ratio you want..

Sorry to chime in the thread.. didnt want to hijack. just mention we have them aswell..

Thanks
