Cam ?

[muddevil01]

I am wondering if I could use the aspire roller "rockers" and such with an aftermarket cam(FMS)? Is there any benefit to doing this? A friend of mine used the aspire stuff in his stock B3 and he said it made a difference in throttle response. I don't know if this is true or not so I thought I would ask here to confirm it thanks

This is on the FMS site with the cams:


PART NAME PRICE DESCRIPTION
155-10

Festiva/Aspire Competition Camshaft

$160.00/ea

All new performance camshaft. Uses Hydraulic rocker arms. Great for street/strip. Makes power from 2500 RPMs to redline. Good idle.
155-11

Festiva/Aspire Race Camshaft

$250.00/ea

All new performance camshaft. Uses Hydraulic rocker arms. Power from 3500 to redline. Recommended minimum 10:1 compression. Rough idle


If I remember correctly someone on here said that they tried it with no bad effects, but ..... FMS says no to roller rockers with their performance cams.

This has been the subject of many discussions before. Try this thread;
Also, there are several other threads in the Custom Engine & Drivetrain forum. Just do the search in the forum, there's a ton of info and it will be a lot easier to direct you to it than go through it all!

Aspire uses a roller cam and followers, naturally this means less friction in the valvetrain, so possibly slightly more power/better mpg. Oh yeah you can safely run oil that lacks ZDDP too.

Thanks for the link that's enough to make me not do it. However when I called FMS and finally talked to someone they said that their cams could be used in the Festiva and the aspire with out changing anything else on the motor so this confused me because I thought that aspires had the roller setup from the factory. Thanks for the help

Every Aspire I've taken the VC off of had the rollers. Supposedly the carb cam with the hydraulically adjusted rockers is a good combo. I remember we put in a carb cam and manually adjusted rockers on an Aspire. It pulled hard up to about 2500 but almost no power at all cruising above 3k (might not have been so bad if it hadn't been an auto though).

[muddevil01]

That's a good point the carb cars didn't have hydraulic rockers so according to what has been said here you couldn't use a FMS cam in a carb motor without changing to hla's am I correct in this assumption if so if so someone should inform whoever answers the phone at Fms that you can only use their cam in the aspire and carbed Festiva if you swap the rocker assembly I just hate getting told two different things. It is confusing although it would be alot better if I could get more info on the cam but that isn't gonna happen

I have the Competition Camshaft with Aspire roller rockers and I have had ZERO issues

[muddevil01]

How long have you had it? Are you running stock springs?

I have an Aspire engine with an FMS performance cam, and HLA rockers out of a '91 Festy, in an '89 LX carbed car and it runs great. Of course this doesn't answer your question. I used the roller rockers for a long time with the original Festy cam and didn't have any problems, just always knew it wasn't right.

From what I've read that is the way you are supposed to do it I was trying to get better performance with an after market cam, with a little better lower end throttle response with the roller assy. with out getting a custom ground cam. I still don't know if using a roller assy. the benefits out weigh the risks(price)
