Best Cam Upgrade for a B18c2?

Hey fellas!

I'm looking to upgrade the cams in m VTi-R, and I'm just wondering what Cams you recommend for this motor.

Supporting mods will be Skunk2 IM and TB, with an Injen CAI.

Would Type R cams give the same gains say Skunk2 Stage 1 cams would?

Thankyou :)

whats your budget?

if its kinda low then go whole type interanls... but you should invest in a type r gearbox first... sell your vtir box then with that money buy type r internals

as above, whats your budget and goal?

if you want similar gains to Type R cams, perhaps have a look at Buddy Club Spec III+

no drivability loss for street and its pretty much drop in and go (no stand-alone ECU neccesary), however i'd recommend changing to OEM ITR dual valve springs. do you have a good header and exhaust setup already?

the problem with the B18C2 is that many of the aftermarket cams require ATLEAST the compression ratio of ITR.. are you considering building up your bottom end with some hi-comp pistons?

also, +1 on changing your gearbox first. will do heaps more than cams will.

speaking of buddyclub spec3+ cams, why doe's everybody compare them to ITR cam's when the spe3+ yeild a longer duration (in-296/ex-290). while the ITR's only have (in-243/ex-235). i have spec3+ in my B20b/p72-head. i notice more mid/top end. so they should be a better choice. would someone please tell me different?

i dont know about anyone else, but the reason i compare the two is because their lift values are almost identical. my presumption was the longer duration just placed the power-band higher in the rpm range..
from what I have gathered hearing through various people and seeing some dyno sheets (dont ask me for them as i cannot be bothered with uni exams going on) is that the difference between OEM ITR and BC III+ is marginal. however, going from B18C2 to BC III+ is well worth it.

Touge Tom, you mentioned u had the P72 head, correct? thus i imagine you would have noticed quite a significant gain over the stock cams...

Yeah definatly. Reason why I bought spec3+ was to increase my rev range. Cos having the longer duration would help me reach 10k+. Just haven't gotten round to buying a hondata s200/300 yet. Still running it of a p30 ecu.

wholey abortions touge tom...... u want to rev ur b20 vtec to 10,000 Rpm.

what specs is ur motor if u dnt mind me asking?

I reckon get an exhaust first, then build your head (the whole thing, not just cam-swap).

Fully built. All forged internals. Welded in block guard. 13 compression 84.5mm pistons. I/m/h/e. type-r g/box. Spec3+ cams. 71mm/tb. I've just been too lazy to get round to doing the ecu. Runs great. Its daily driven, not garaged and hidden for just the weekends.

Thanks man, this is the type of answer I was hoping to get.

My goal, and why I was looking into doing this, is I'm after abit more sniff in the mid range. I would just like abit more power for those drives through through the mountains. Im not looking to build a straight line warrior. Anything that can put me close/equal to a stock Type R I guess?

As for Headers and Exhaust, no I do not have a good set up yet. The more I research the more Im realising I should probably get my engine breathing properly before upgrading camshafts. I think I'll finish off the I/H/E combo, then think about swapping these cams.

As for building the bottom end, I'm not sure if I'm prepared to go that distance just yet. That's why I was looking at the Skunk2 (and now Buddy Club) cams because they are designed specifically for the C2. The Buddy Club cams infact look like the best option.

Along with another $150 for OEM Springs and Retainers.

Realistically, would I expect to see a vast improvement over the stock cams?

Also thanks MikeyG for your input too!

And as for budget, considering the AUS $$$ being so strong, I was hoping to spend somewhere around $550 shipped?
