I know some of the saturn guys are doing it. the intake cam has more lift and duration, so would it be possible to run two intake cams?, just a thought.

 

the intake cam won't fit on the exhaust side.

 

i know on a gsr you can run the intake cam on the exhaust side and run another cam on the intake. You should upgrade the springs.

you don't know what you're talking about. u can run the intake valve SPRINGS on the exhaust side, but you CANNOT run the intake cam on the exhaust side. There are cut outs for the distributor. get your facts straight. there's a reason why there are two separate cams.

OWNED!

 

i pretty sure u can, because i wasnt paying attention one time i was building a head i put the cams in reverse and didnt know til i went to bolt distributor up.

okay. since you're building a head, why don't u take pictures and show us that it fits and runs?

 

READ i didnt say ran, i said the intake cam bolted where the exhaust cams goes. If people are spinning honda engines backwards and using stock cams it is a possibility. Also i have built 50-60 DOHC vtec heads . I would like to hear about this from somebody else.

 

I'm not questioning you, but if you've built 50-60 vtec heads, shouldnt you know if this is possible from experience??

 

i wouldnt know never tried. i am just worried about valve to valve contact.

 

anyone who thinks that you can put a intake cam in the exhaust cam location is, quite frankly, an idiot. and if you're a "engine builder" who has done, attempted, or accidently done this...i think they should close down your shop, take away your tools, and send you back to school

Please...you're not perfect and neither is anyone else. Everyone has brainfarts and this case is no different.

Also, I don't think that valve to valve clearance would be a problem. A lot of the more aggressive cam setups use exhaust cams with more duration and lift than a lot of stock intake cams so I don't think there would be any problems installing say two GSR intake cams and getting it to run. Wouldn't it be possible to install a combination like this and turn over the motor a few times just to check. I think it would be worth it just to see how well it would run. I don't think there would be any issues with it running, but there may be some slight modifications that need to be done to the end of the camshaft.

yea you could probly make the dist. notch and it would run fine.

But the distributor notch is on the intake side, so if you're running two intake cams you shouldn't have to worry about it at all. I do think that you will have to do some major adjusting and tuning with some adjustable cam gears though.

 

interesting, maybe ill try it on mt d16z6

couldnt you just get a regring in the exhaust cam with the intake cam specs?

good call. been away from the car too long i suppose. anyways. ill try it in awhile with the LS im taking out of the hatch and using for a ghetto build up motor with all this snazy sh*t i think of all the time.

 

when u work too long or do something sometimes u slip up, it might be for the better though. Some domestics run a cam with the intake and exhaust duration and lift the same. I don't fully understand split duration cams with a turbo application, nor the benefits of this with a ported head, since the intake to exhaust cfm ratio would be different. Anybody else have any theories or sugestions?

 

It depends on the turbo if you run split duration cams on a turbo application. I believe it would be more beneficial to have the longer duration on the exhaust side though, it would make for better turbine efficiency, and the shorter intake duration would help to prevent too much air from entering the combustion chamber under boost, which could cause the engine to lean out and detonate. I don't know, just speculation.

 

if not enough air is entered through the intake wouldnt it go rich and not lean? i think the extra lift would be benefical to n/a and turbo cars to a point.

 

i never said that i was...but for the people out there who said they HAVE dont it before, and it works fine? eh...ok. MAYBE, just maybe i'll give it to you if you happen to lay down the cam and then quickly notice it. but if you start torqueing down the cam caps and you still dont notice, then somethings is definetly fishy.
