d16a6 wanting to upgrad cam
for the DOHC guys i know there are alot of swaps for camshafts but what about us SOHC guys? i have a 90 ef sedan with an si obd0 d16a6 swap with the stock cam shaft.
what other SOHC cam would fit? also which would be better than the stock si cam?

well yea i know i could just get another head but i dont feel like doin a mini-me.
plus the cops over here are weird, i've gotten pulled over 4 times in the past 2 months in the same area. not once have i gotten a ticket but they get me for my exhaust, checking to see if i have the keys to the car, **** like that so if i get the head popped and they see "vtec" im screwed.
but ok a zc cam? i thought zc was dohc?

so Delta manufacturers after market cams for D series? better than the ZC? im just looking for a little bit more pick up at higher rpm. with the si tranny, the car is torquie as **** but once i hit like 100-110mph its between 5500-6000rpm. whats the redline for the obd0 si?

as for the zc cam, yes they are a good cam but good luck finding a legit one and being able to identify it vs. a stock a6 by eye. as for which is better, IDK. never seen a dyno comparison between the zc and any other cam.
redline is dependent on which ecu you have. some are 6800, some are 7200
Trending Topics
Fuel cutoff on the Si is 6800 cold and 7200 warm. I dont remember the exact temp. but its been tested and known for sure.
The ZC cam is said to be marginally better...and there is no dyno proof. Like ryan89crx says, you wont ever know if you've bought a legit one until its too late.
I've been researching around for the mildest possible cam upgrade you can get for an A6, and there is little to no info on them out there. I take the idle/mileage feedback from any cam maker with a grain of salt... its probably worse than they want to say.
Furthermore nobody just dyno's their camshafts on a stock or bolt-on'd motor. When you see results, the head is built, the block is built, the header costs more than the car...etc.
As for Delta cams, I hear often people say "Delta will give you any grind you want for $100" but if you email delta, they will only offer you one or two of their typical grinds, and researching both of the recommended ones they gave me found that they are nothing at all like what I was asking for. So why not give them the exact lift/duration I want? I would if I had the slightest idea what those numbers mean in terms of power at RPMs, idle quality, mileage...even just a vague idea...but there is no reference point.
Finally, I agree that going VTEC is a huge can of worms when you consider the ECU, gaskets, T-belt etc... I think the tradeoff though is the car will have better mileage and idle better than a comparably-cammed-up non-vtec motor, plus you have a better idea of what you are getting into. The stock vtec motors I've experienced feel a little weak in the low/mid range compared to the Si, but much better in the top...maybe that's better when its a higher-compression mini-me though.

i was pleased with my mini me swap. i had an a6 block with a y8 head using an obd0 b16a ecu. with a gutted interior i ran a 9.5. nothing to brag about but pretty damn good IMO for a basically stock single cam. and i think we put it together for less than $500. but we did get the head for free.

i was going to go z6 head but its not worth it. y8 MIGHT be worth it but just costs a little extra since its obd1.
why would you go with a y8 over a z6 head? manifold, sure, but head.. no thanks. and the z6 is obd1..

anyway, the sohc zc cam is the way to go..
your best bet is either a delta cam or a bisi cam...
vtec in the sohc motors is overrated.. spending 500+ on a mini me swap and gaining next to nothing in power is kind of pointless

I have a Bisi level 2.2 in my a6 and I have had good luck with it. I think the a6 head is better than a z6 or a y8. Spend the money you would have spent on a vtec head on a obd-1 conversion, a chip burner, some kind of software, and a wideband.
off topic....
my clutch pedal arm squeeks like a bitch when i push it down. also when it comes up sometimes. anyone ever have this damn problem? if so what did u do?

Go to Bisi's site www.bisimoto.com, get his phone # and call him. He is one of the nicest people I have ever talked with.
we went from running a 10.2 with an si motor to running a 9.5 with the a6/y8 combo. i think almost a full second off your time is worth $500.

buy a cam for your a6 and with the money saved up your compression, etc... and run more than a full second off in the 1/8th
and honestly if people are looking at drag racing a car.. then odds are their not messing with stock mini me's etc...
its all in what you want from the car
didnt somewhere above you posted saying you got the head for free? not everyone gets free parts
