Hi guys!
Do you know if there is someone who produce more performant cams for 7AFE engine?
the only site I found with aftermarket cams is Import performance
which sells TopLine cams. Who know about this manufacter?is it good?
Also, does anyone know how to get regrinds, valves and springs for better performance and which are stronger than stock?

Thanks wink.gif wink.gif wink.gif wink.gif

you'll have to get them custom re-ground, or just custom, period. no one makes performance camshafts for the 7afe. why would they? it's an economy engine. and besides, to get decent power, you'd have to go with such a high lift that your idle would be terrible, not pleasant to drive on the street. i'd expect about a 10 HP gain from getting your camshafts reground.

My advice to you is to swap with the 4AGE 16v/20v

I know West, but in Italy I'm going directly to jail if I do a swap and I also loose the insurance coverage in case of accident.....that's the way I don't do it. frown.gif
Check in my profile my performance mods. If I'm going for a reground, which duration values should I use? confused.gif

yep, that can also work.

I think the automatics have a slightly bigger cam than the manual.

Either way, if you are going to use a manual later, it is wise to get a manual ecu or an aftermarket computer since the maps will be set up differently.

it depends by the type of accident.....maybe if it's cause u're going too fast (and in Italy we ALWAYS go over the limit.... rolleyes.gif ) there are some complications......anyway....do you know which durations may I use for cams? wink.gif

Ok.

I believe that you duration right now maybe 228 -234.

If so, 254 - 262 maybe go.

Cranecams or MSD will help you out here.

You need to get a cam to operate in the engine sweet spot..

If you are going cams, get a customer header build bu pitshop or some other muffler dealer..

with new cams, look to increase air flow filter , 2.2 -2.5" exhaust with high flow muffler with increase of fuel for more HP & Torque

I all 256 or all 262.

It maybe better to go with 256 since your engine might now be able to rev to 8000rpm.

no, cams don't allow you to rev higher, valve springs do.

there are NO cams for the 7afe, i don't know why you people are all talking about like 256 and 264 for.

there's basically only 1 way to regrind your cams. webgrind or weber cams or something like that, reground some guy's 5sfe cams. it was like 600 bucks i think. but if you're in europe, i have NO idea.

I think you're not right charlie....the cams let you get higher RPM band....Of sure if u're going to get more RPMs you need better valve's springs to avoid the risk of a crap wink.gif ....also better retainers are suggested for high RPMs, but as I know are the cams that let you reach an higher RPM band....

Hi guys, please read carefully.

I stated that he should get cams in the engine sweet spot.

If you get big cam, over 262, you will have to rev a little more for more power.

These is also the problem that the engine will not be able to use the big cams due to small ports and vavle size and other small factors.

Is that clear enough?

I believe they regrind your stock cams...

Anyways, there's no real point in going with performance cams unless you're gonna build an all-motor track engine. I mean, re-ground cams idle like crap, typically shift the powerband into the high rpms, and make a daily driver drive like crap, especially since the 7A is already a fairly weak low-end motor.

And... why do you keep telling people to get 2.5" catbacks? That's too huge for 4 cylinder cars, even 6 cylinders. You'll lose more than you gain.

And about revving... your stock cams can rev beyond redline... it's the ECU that automactically cuts fuel... The revving isn't limited by the cams, it's the electronics.
