At school this guy keeps talking about piggyback cams but hes full of crap and noone knows when hes telling the truth.

The thing I am asking is what is a piggyback cam if there is such a thing.

He says his bluebird has one but I looked in his bluebird handbook and its SOHC so I'm confused.

I looked up on the internet for anything but it was talking about piggyback cameras LOL.

I asked the guy today what exactly piggyback cams are and he changed the subject so its hard to get an answer, I am beginning to think they don't exist and hes full of crap.

2T-G, 3T-GTE and 18R-G all use a dummy cam in the original place to run distributor/oil pump/fuel pump, as well as the twin overhead cams.
I think this guy is just talking out his arse though.

Cool. But would any of this make a car go faster anyway.

Heh, no. You cant add a 'piggyback' cam to a motor. Its just a different design, will only add more weight, not any faster or superior to a car with a conventional design.

I knew it. This guy's a joke. He looked at my engine this morning and was like, oh nah its not piggyback cam. Now I can say so what.

Thanks for your help

Haha I hate it when people talk out their asses and actually get people to believe their story.

Like this dude I know, "My dad blew the head gasket spacers in his van".... Ok then I'm sure it would be smart to have a spacer or washer spacing the head or block from the gasket :roll:

Yeah I have heaps of them at my school.

One guy once said.

Oh we were driving towards the railway line in this RX7 and a train was coming and the turbo hadn't kicked in so we had to hit the Nos and we just got over the railway line before the train went past.

Everyone looked at him and was like. "Why didn't you just brake?"

Or the same guy said once.

We were in a Pontiac TransAm and we sped up and we were going 300km/h and we went 10 kms in 45 seconds.

Oh right: to actually go 10 kms in 45 seconds you need to be travelling 800km/h and I don't think you can do that in a TransAm.

Some people aye?

I spose you could say an F series head is piggyback,as in it runs the inlet cam off the exaust cam, not that it means SFA.

I really hate that kinda person eh, im sorry but watching 2F2F and preformance car tv makes you no expert :lol:

He might have been talking about a head gasket shim. We've only used one once at work when we had to machine quite a bit off a head, we used a spacer sorta like a template that comes in different thicknesses, to set the compression back to where it was.

by **FLAWLES** » Thu Nov 17, 2005 10:26 pm

hes not talkin bout balancin shafts?

but yea some engines " air cooled " use shims/spacers has head gaskets u get diff sizes to
