On my SIR-G my current set up is:

AEM CAI
High flow cat
Apexi N1 exhaust
DC JDM 4-1 header
Fidanza 7lb flywheel
Exedy Organic clutch
VAFC2
FPR

Before the flywheel and clutch the car was running 14.6-14.7 at best . My goal for this season is to hopefully get a 13.7-13.9 out of the car. Since I already have just about all the bolt ons except Skunk IM, im trying to decide what internal set up to go with. The car is a daily driver so i need to keep it as reliable as possible while at the same time making as much power as possible to reach my goal.

My options for cams are CTRs or Skunk1s
Pistons can CTRs but based on what I have read JDM ITRs may be a better choice for me.

Out of my options listed, what seems to be the better choice to get me where I wanna be ?

 

?

 

Sorry for my ignorance what's a sir-g again? b16 or b18?

jdm gsr

 

yea, difference of 10.6 compression to USDM 10.1. Very good swap to do if u can get away with it with your local law

 

I would say go with the ITR's but that is just me. CTR's will sit you a little high compression wise. Also, if depends on what you are looking at doing... so far, it seems like you are doing an all motor build so I would look into TODA. http://www.todaracing.com They are the **** when it comes to all motor.

All in all.. I (being a SiR-G Owner) would just spray and call it a day. With a 55 wet of NX, you will be doing 13's easily. Daily driving wont be a hassle since you can turn the bottle on and off or even take it out.

go with the itr's

 

yea you got a point there, 55 show and CTR cams right

 

With a 55, I would keep your GSR or SiR-G cams... These cams are the best for any kinda F/I Applications... Thats unless, you go with a nitrous cam.

 

i think ii still want a 13 second all motor car first

 

In that case... ITR Cams, Springs, Retainers, Drag radials, ITR Manifold, skunk2 manifold, and a VAFC will get you there.

 

yea and a 2.5 inch exhaust

 

accoroing to the C-Speed calculater which may or may not be correct, my options are:

CTR Pistons and OEM Head gasket @ 12.0 compression
JDM ITR Pistons + Mugen head gasket @ 11.6 compression

Or I can spend a couple hundred bucks and get fordge JE high compression pistons which may be a waste of money cause I dont plan to increase my redline.

So basically between those choices, I want which ever one i can drop in my motor on my GSR rods with no modifications required, and will run efficiently with for daily driving and still make good power.

I have also decided that since im not changing the red line that im just gonna go ahead and run with CTR cams

 

For daily driving, I prolly would suggest the ITR pistons.

FYI... this is gonna cost you some money dude... machine shops arent cheap... thats unless your doing it yourself.

 

so whats gonna be the expenses besides parts
