B16b/ITR B18 camshafts in a B16A2 - a quick question

Hi,
I know that the standard internals can take these cams without any modification to the pistons or valvetrain etc. As far as i know, they can just drop straight in, pleasecorrect me if imwrong. The standard b16a2 cams see the engine rev limit at 8500rpm, butive readengines using these cams to rev limit at 8800rpm(theB16b and 2000 ITR B18). Would i need to have the rev limit adjusted, or should i keep it at 8500rpm toretain a bit of a safety margin for the standardinternals?.Any experience here with B16b/ITR cams in a B16a2????

captain_slow,

if u want to explore the full potential b16b/b18cr cams u will need to adjust the rev limiter. whats ur ride? i guess an EK4 as u said ur rev limiter is set to 8.5k (for stock obdII ecu)

my ride is a 2dr Ek4 with obd2 ECU with 8.5k rev limit [:'(][:'(]. i've upgraded the cams with b16b cams+vs+retainers.but head job n adjustable cam gear upgrade still pending due limited budget

one of my future upgrade is to get my ecu and obd1 ecu chipped where the rev limit is increase to 9k. i am agree with you type R cams can produce power up to nearly 9k. if i m not mistaken, there are 2 ways to adjust the rev limiter for obd2 (stock 96-00 EK ecu).1st it needs to be convert to obd1 ecu (EG) and get it chipped, the other way is using a piggy-back management like E-manage Ultimate.

where u base at anyway?

I drive an EG b16a, and im based in the UK. It seems from research that i can drop the B16b cams inas they are, if i want to rev up to 8500rpm, but i will need b16b valve springs and retainers if i want to rev up to the 8800rpm and allow myself to safely squeeze out the max potential of these cams. I'll need some skunk2cam gears or something aswell to retain the valve timing

You will want to get the air fuel ratio tuned too, as you are not going to be compensating for the higher revs.

i see. meaning tht ur EG ECU is an OBD1 and shouldnt be a problem for you to get it chip. I bought my 2dr EK when i was in UK. it was brought back to malaysia 2yrs ago and from that time i started to mods my ride accordingly. my goal is to get around 200bhp (+- 170whp). It is achieveable with type R parts and i m going to go for that route since used type R partsare the most economical.
