I plan to drop in a set toda spec C2 cams in my integra type r,so i wonder what i should upgrade to use those cams. :help:

Here is my engine spec
port n polish head
Supertech Valve Springs n Retainers
aem cam gears
PCT civic type r piston
ACL Race bearings

 

A tuning system like Hondata/Neptune/EC-tune etc, whatever a good local tuner is comfortable with.

 

S300, also i would suggest a fuel pump and injectors. may as well if your getting it tuned. and maybe a 65hp shot of nitrous... just saying

 

don't put the cams in till you have a way to tune it. I'd personally recommend using neptune and a innovate lc-1 wideband.

 

Toda C2's are pretty big cams, make sure you have a fresh timing belt

 

Yes i dont make the same mistake i did. In my high comp b16 running toda C's(small c). Reused my timing belt that already had about 40K+ on it. I ended up Standing on the side of the road scratching my head thinking " i swear i tightened the tensioner" The belt will strectch and come off the gears.
I later reinstalled the head with no damage luckily(thank you stainless steel valves) and reused the timing belt and saw it flapping on the tensioner side during quick blips of the throttlebody and it flap vigorously under engine decel on the non tensioner side. BTW i used the Hangar to tighten the tensioner.

The belt will get stretched quickly with cams with big primary lobes. I switched to a greddy timing belt(kevlar reinforced) never looked back.
btw what is the service interval of a greddy,gates,toda timing belt when using them with cams like this?

 

toda and greddy timing belts wear alot better then stock, changing them depends on how much abuse your putting them through i don't know if there is an exact change date. each engine will be different. I've ran my Skunk2 pro 2's for 1000km's and the belt still looks brand new. (which it should) i don't drive my car to hard though, a 10lbs nitrous bottle every 2 weeks isn't that bad. the thing i F*ed up on was running a stock fuel pump. i ran out of fuel at 8500rpm NA, and 8000 with nitrous. not saying i would run a stock bottom end B16 past 8500, but it would have been nice to hit 8500 with nitrous. my skunk2 pro2 cams were making 10 wheel HP every 500rpm's so that would have been a nice increase.

 

I would also look into a second timing belt tensioner that bolts to the head. Endyn and Vibrant make them and not sure if they are on the market yet RCG has one also. It will help with what tempsohc was talking about. I have Toda C's also and already have a RCG tensioner, its worth the extra cash IMO.

 

Like some one stated up above. You will need bigger injectors. Look into RDX 410 CC injectors. So far im loving them on my poormans ITR setup. Also saw a good increase in MPG.
GL.

 

my engine is b18c gsr block with p73 pistons. cams tod c2. but my head is b16a untouched. so what your opinion if i go for port n polish?will my torque increase dramatically?management using hondata.dyno result 193hp 17.82kg-nm.
please help guys...
