Camshaft question

[Juhkeeb]

First off I'm a noob but I recently got my first integra and I'm really interested in learning. But for my question. I bought a 98 gsr, b18c1 with full bolt ons. But the previous owner said that the stock camshafts were replaced for ITR camshafts. So like I said I'm a noob, I'm not 100% sure if this guy was just talking out of his ass trying to make the car sound better. But what I'm wondering is how much of a difference would having ITR camshafts in a b18c1 do? Hp differences from stock gsr camshafts to ITR chamshafts? Or is it just pointless for performance? Could someone please give me some feedback, thanks!

Slight increase in power and VTEC crossover is different I think

get a tune to really get the benefits. maybe 10whp as is no other mods or tuning

ITR cams are definitley not a pointless mod, but to get the most out of them you need a compression increase. ITR's have 10.6:1 stock compression, GSR are 10:1. You also need something to adjust the a/f ratio, has that already been done?

I'll trade you my gsr cams and cash for the itr cams

ITR cams are a good gain.

at RACELINE USA a stock gsr is around 140whp, one with bolt ons is about 160ish and i dynoed at 177whp with a mildly built gsr

Thanks for all the feedback everyone.

Thanks! Well im thinking about doing a turbo build to this and iv read about high compression being a problem with that, do you think increasing the compression to help the cams and boost would be worth it or too risky? Just keep the compression the same? And im not sure about a/f ratio.

unless you sleeve your engine and add forged internals do not bump your compression past 10:1. compression is only party of the puzzle. it really depends on your goals. you can boost on 11:1 but you need a really good tuner....

today's tuning technology is light years ahead of what it used to be. do not bump up your compression now for the miniscule power increase for your cams if you want to boost in the future. instead spend the money on some cam gears for when you boost so you can tune out that overlap

Again this is my very first car, so im clueless on what that is. Obviously me even thinking about boosting my car is pretty much a joke because im so uneducated but im learning everyday and plan on learning more.

Yea i didnt mean change the compression now to get the cams full increase but im saying later on with boost, too risky? il keep the cam gears thing in mind because another one of my questions is how can i get more HP besides fully building the internals or forced induction?

How? More bolt ons. You should list what you have in specifics so we can get a better idea of what youre working with. I wonder if he really does have itr cams in the car or not. No way to know without looking. You should ask if you can, if he changed the valve train at all when he added the cams and if it was one cam or both. Do lots of reading. This is how i learned what i know so far.

And yeah most people saw an avg gain of 10whp just putting the cams in. Theres more potential with better modifications.

Aem intake/Skunk2 manifold. not sure what but after market headers and not sure what but fulll 2.5 in exhaust. So yea full bolt ons. but i have no way to contact the previous owner so kinda screwed on that..

if you're looking at a turbo then do not raise your compression or get a header.

why would you increase your compression? you really need to do some research and come up with a budget and a goal before you do any more mods to your car.

 

[NemesisCBR]

Actually you can tell if he at least upgraded the valve springs for the exhaust side assuming he dd both cams. He will have added dual valve springs to it if he did. I think if u take off the cam caps you can see the part you need to id the cams. Someone correct me.

To sum it up and very generalized.. all motor high compression, turbo you build the internals and leave the compression.

 

[Juhkeeb]

I really didn't plan on building the motor till after turbo. It's just way too much money for me. Iv read and people say up to 8 psi is safe with a good tune so I planned on trying that route. Again I'm new and I dont need people hating, I need help.
