Thinking of getting skunk2 tuner stage 3 cams for my Dc2r

Which pistons would i be best off using for these cams
Wiseco 11.8:1 - 12.25:1
Wiseco 12.5:1 - 13.2:1

Car has neptune ecu
Decked Block 0.001
Toda exhaust mani
Custom 3" exhaust from mani back
Velocity stack with filter
Cold Air Feed
Supertech Valvesprings Retainers
Adj Cam Gears
ARP Head + Rod studs

Are these cams to much for this setup would i be best off going with tuner 2s
Any other cam/setup recommendations welcome

 

Wiseco 12:5:1
this is the proper ratio you should run. And if you wanna bump the comp up some more run a thinner head gasket or mill your head down.

Make sure your supertech springs are the SPR-H100DR(springs w/retainers)

Pro series(skunk2):
Springs rate: open-80lbs
Springs rate: seat-226lbs


Supertech(SPR-H100DR)
spring rate: open: 85lbs
spring rate: seat: 266lbs

You will run these fine. Please make sure that if you are building this motor yourself your piston to valve specs are good. Wiseco makes forged pistons so they expand so specs are diffrent from cast.

Hope this helps!

 

Is this a B16a, B16b, B17, GSR, Ls/Vtec, B18c/5, B20 Vtec? Any headwork? You having Neptune - are you going to have it tuned? What octane of fuel will you be using?

 

Bigger is not always better.

Tbone made 20 MORE hp switching from a stage 3 profile to a stage 2. This was on a 13:1 2 liter.

 

Thanks for the advice.

Its a b18c jdm type r.No head work.Will have it tuned straight after the build and will be running on 95 ron.With that octane could be risky runing the higher compression of the wiesco pistons.

Thinking now my best option could be the tuner 2s as anything bigger could be over camming.

Will aso run eagle rods with the pistons and thinking of going with supertec valves and rdx injectors

 

Get tuner2's and you will never look back...

 

+1 on Tuner 2s, or BC IVs.

(The BC4 will give you a bit more midrange, both cams will have the same high lobe)

 

95 octane? I'd go with the bigger compression and:
