Now I'm getting uprated cams soon for my car, now the question or opinions should I say as I keep asking myself am I just wasting my money over gucci'ing it.

I have Jdm/spec c heads which have already the uprated cams (8250 rpm) on avcs heads.
Now given that I already have a decent redline, am I wasting my money going for wilder cams to create a bit more rpm, is it worth the cost vs benefit?

I know what I want and if the cost is x amount then so be it but I need a good enough reason to sack the idea lol.

I'm having my heads fully refreshed at same time with uprated valves and springs also.



Thanks

 

I would say it is down to perhaps how you use the car.

If you are mainly on track and are most of the time high up the rev range then I would go for it. Assuming that your bottom end and ancillaries can easily cope with it all.

For a road car I might personaly give it a miss. As those upgraded AVCS heads will be more than enough.

Each to their own. But my thoughts.

 

 

This is the thing, it will be a weekend track car that will get driven hard and that extra will help I suppose so yes id like it to be capable.
I think i will go for it so its there when i need it, better than not.

 

I’d Slap them in with a big dirty turbo aswell

 

Don't want a 'big' turbo, want it very drivable low down and with a nice top end to match. (Maximum power band)

 

You would be better timing in the spec c exhaust cams correctly than using the generic timing cover marks, with vernier pulleys, you can then tweak the timing to suit your engine power/driveability requirements, the spec c cams are very good for what you are after.

 

Ah, now there's something to look into, never knew you could do that (go outside of stock alignment with them cams, I thought they were set?)

 

Why do you think adjustable pulleys are made for, the alignment of std pulleys & marks are way of in most cases, you can tweak the timing for low down torque, or top end power.

 

I always assumed if going for adjustment pulleys then there are uprated cams and a big turbo to control timing a bit better for such a large power figure etc, never knew it was beneficial to just add adjustable pulleys on their own for more gain etc.

 

Is this a engine out job to do?

 

To do it properly yes, its an engine out job, as you will have to use a dial gauge on the cams, & a 360 deg protractor disc on the crank, to dial the cams in.
