I recently got a set of Stage 4 Jun cams. Does anyone know what they go for and any comparable cams out there? I may end up selling them and getting a smaller more streetable cam. So i just need some ideas. I'm new to this all motor stuff.


Current Set-up
b18C5 Benson block
Bored to 85mm
Eagle Rods
CP 12.5 Pistons
LS Crank
Clevite Bearings
Type r head fully ported and polished
Jun springs and retainers
Jun Stage 4 cams
AIR carbon fiber intake
Walboro fuel pump
AEM fuel rail
310cc Rc injectors
All new Earls fittings and fuel lines

It made 224whp tuned by Cortney Green but sadly spun a crank bearing so i have to rebuild the motor any ideas on changes i should make?

 

84mm's would have been streetable..85 is already pushing the limits..dont u think?? keep the stage 4's if u made that little power on stage 4 cams..i wouldn't go down..i've seen setups with less make more..
my suggestion would be to be looking into the pro 2's possible the pro3's or bcIV's..

 

Yeah i bought the car this way about a month ago. 85mm is pretty big, but what can i do now. Cortney thinks the motor is easily capable of 25-30 more horse. He just tuned a hatch with close to the same set-up and it made 247whp. My car had a ton of problems from day one. So this time he wants to build the motor and get it right.

 

I would keep the Jun 4's, just have them degreed. Are you using oversized valves?

 

Yeah i am

 

i dont think 85 that limit pushing, ive seen a turbo b20 vtec that was sleeved to 85mm and it was fine and it dynoed like 537whp andlasted until he got tired of it

Be careful...Jun 4's with oversized valves doesn't allow allot of room for clearance.

 

Yeah Cortney Green Said its a tight tight tight squeeze but it will work. 86mm is the biggest bore i have ever seen on an all motor build but 85mm is the biggest you can go with a turbo. I think that Mr. Green is on 84mm and he made 871 horsepower and 554 torque.
