I am interested in the crower cams based on their low price.
I have plans in the future to use a supercharger, but this will be a while (probably a year).

Crower has the stage 1 and stage 2 cams, both of which I think do not need head work.

Stage 1 - 268/268 .362"/.326" (9.1948mm/9.1948mm)
Stage 2 - 276/280 .374"/.393" (9.4996mm/9.9822mm)

Stage 2 is recommended for forced induction applications. I have an NA, will these cams still give me more horsepower and run reliably? I am not too concerned about a rough idle. These cams are actually cheaper at nopi than the stage 1 cams which is another reason to wonder.

I understand that more duration and more lift is not always the best, but I would guess that the quite significant increase of duration and lift (as seen in the stage 2 cams) would make more power.

What do you think?

Depends.... as I have the MAF version of the GZE just like the "USDM" s/c AW11, I dont think the stock GZE's ECU would like anything higher than stage 1 cams. Then again, my opinion is just that... an opinion. No proof other than what I currently have in my stock "bluetop" 4AGE: HKS 256/264 cams. Slight loping idle....

Ok, so it might not help at all, do you think it would hurt at all?

Hurt? While it would give more torque due to higher-than-stock lift, the greater dur would just shift the powerband up higher up the rpm scale which you may or not like....

As I am a dragracer at heart I would recommend gunning for them, it's just that you will have to take fueling and timing into consideration as vacuum would be less than optimal at part throttle. :goodluck:

2nd edit: If you go for the stage 2 set, I think youhave to do something about the rest of the valvetrain. That is one heck of a lift figure. Upon installation of the cams you HAVE TO degree them to the recommended specs (duh!) and it seems that a good quality header must be used. I'm really curious about the hp outcome on this set. ;)

Thanks for the detailed response :)
I do have a KBD header that I got from ebay, seems to work ok.
I like those high up torque revs, and I'd like to see more of them.
I guess I just need to see if I need to modify my valve train. I will email crower directly for that.

What's your drag setup? Do you have a website for your car(s)?

I have an '85 AE86 with a supercharged stock "bluetop", Maxmisawa's clutch setup, an open 4.10:1 geared Hilux rear end, lowered of course and welded lower link brackets to accept lower links from a cressida. Works pretty good, if I can modulate the tires to spin less at launch.

Nah man, too much concentration and focus on the AE86 to keep it running. Besides where I live everything is double the retail price when ordering. :eek:
