Cams For Turbo Engine

[Cold Fusion]

Hey i have crower Cams, Part 62403-2 which are the Street/Strip package. now i am now thinking about going turbo, but i have these cams and im not sure if i can use them in my turbo engine or not...would anyone know? are they even worth putting in? i am very confused!

thanks

just guessing and without looking at specifics.... If the cams you have are for High Compression NA power you might stuggle with boost as the excessive lift may put to much pressure on your drive train etc..

If i am wrong someone will surely correct me, but I havent heard of anything more agressive then a Type R spec'd cam for Forced induction other then a specific turbo cam, now I cannot possibly comment on your exact cam, just to say that if it is a massive duration/lilft cam designed for NA then it might not be appropriate!

As for the turbo question.. I say depends on what you want BUT TO TURBO well.. nuff said!

Cam card here (http://www.crower.com/misc/cam_spec/cam_finder.php?part_num=62403&x=25&y=6)!

The turbo cam is the 62402T-2. Are the 62403-2's used or are they new? If they are new email Crower and ask for an exchange. It's only a $66USD difference for the turbo cam. If they are used find someone there that needs a set and get the turbo cam. Might as well do it right. Also for the ones you have did you get the spring and retainer kit for the cams? http://www.crower.com/cat/import/honda/cams/b18ab.shtml

i emailed them and they said it would be better if i used the turbo cams, and they said they can do an exchange...but now i dont kno if im gonna turbo lol (its a hard decision) but yeh...thanks guys

oh and for other peoples info this is what the email said

I sent-
Hey i was just wondering, i have a honda integra with a b18a and i have brought the following items form you

Part 62403-2 - Stage 2 Cams
Part 84162 - Retainer set
Part 86054BB Cam Gears

Now, i am going to turbo my honda shortly, i was wondering, will the stage 2 cams work in my turbo car? and will i still see a HP Gain? or is it useless?

Thanks.



He replied-
The correct cam would be the 62402t-2, you can run the 62403-2 but you will need to widen the lobe seperation through adjustable cam gears to reduce the overlap. If the cams are new and you have a proof of purchase we will exchange them, if they are used i'll make you a deal on a replacement set. if you have any questions please call 619-690-XXXX.

so yeh,. thanks for the help guys

NA cams and turbo cam doesnt really matter. only if there is a ridculous amount of duration.
blkcrx makes 400kw with a boosted b16 and its running toda Cs which is regarded as an NA cam

[saxman]

most n/a cams have a lot of valve overlap, which really hurts power... doesn't mean you can't make big numbers with them... boost does wonderous things... but it would be much much better with a proper cam

that being said couldnt u just dial out the overlap?

[saxman]

I suppose... but at what cost? If you're going to be running the cam timing so off to get rid of the overlap, I'd imagine you're going to be making huge sacrafices to other aspects of the set up.


There are other things that could help here as well... baffled exhaust manifold, vnt turbos, etc, that help keep exhaust manifold pressure lower than intake manifold pressure, making the overlap significantly less effective at suckign down power

[sivic]

yeah you will be better off just doing it right from the start and going with turbo cams if you're planning a fairly extensive setup down the track. as said, its not really worth compromising for cams which isnt optimum by adjusting overlap etc and making losses elsewhere when its only an extra $70 for the turbo cams. when you look at the specs of the tubo cams they generally arent just designed for less overlap but for more lift than a similar level NA cam.
