Thrrotle body size and inlet manifold for jdm ep3?

[WhitexJDM]

I am looking to get the rrc and was wondering what throttle body I could bolt on too it?? I guess you will need a adpater plate and 70mm throttle body?

I would imagine the bigger 70mm one would be a suitable upgrade, I may be wrong but im sure the stock one fits with an adaptor plate. depends if upgrading for an extra 3-5 ish bhp is beneficial to your build

Hybrid Racing, doesn't need an adaptor plate

Keep your stock TB if your not upping compression ratio. Iv messed about with jdm k20's for a number of years and the best set up for the money 2nd hand imo with out cams or high comp pistons is:

RRC INLET MANIFOLD
FD2 INJECTORS
GRUPPE M INTAKE
SMOOTH INTAKE PIPE (3inch taper)
BUDDYCLUB MANIFOLD
BUDDYCLUB PRO SPEC
5.1 FINAL DRIVE GEAR
HONDATA REMAP.

To run a RRC intake you will need an adaptor in order to use your oem TB or anyother cable type TB. Hope this helps
