4Age Bigport Cams. Difference Between The 2 Types.

[justin_es]

Good afternoon peoples.

I am after a set of bigport cams for my smallport ae93.

 

I was advised that I need to be carefull when buying bigport cams as there is 2 sizes. One size is same as stock smallport cams. 232 I think it is. Then there is the larger ones. 240 I think.

 

Now I have found a set of bigports claimed to be out of a series 2.

 

How do I know what cams are what size?

Or am I miss informed and all bigport cams are the same?

 

Also what are they worth? I've noticed a few people sold and are selling for $50 over a few forums does that sound about right.

 

I have a few sets available to buy but no one can tell me what size they are.

 

Cheers guys. Help will be greatly appreciated. Thanks.

that's an easy one, compare the lift with a digital caliper. Check Bill sherwoods site but I am pretty sure the earlier cams had more lift. So use a digital caliper to measure the total minus the base.

Mirroring what I posted on Toymods, just to help clear any confusion for future reference here:

 

 

 

Not only do 7-rib bigport cams have the same lift as smallport cams' date=' they ARE the same cams. Lets put this to rest - part numbers tell the whole story

 

1984 MR2 - 3rib bigport (bluetop)

Intake cam: 13501-16010

Exhaust cam:13502-16010

 

1987 MR2 - 7rib bigport (red/blacktop)

Intake cam: 13501-16030

Exhaust cam: 13502-16020

 

1987 MR2 - 7rib bigport GZE

Intake cam: 13501-16030

Exhaust cam: 13502-16020

 

1991 AE92 Levin - 7rib smallport (redtop)

Intake cam: 13501-16030

Exhaust cam: 13502-16020

 

1991 AE92 Levin - 7rib smallport GZE

Intake cam: 13501-16030

Exhaust cam: 13502-16020

 

As you can see, 3-rib bigports have a different part number for both cams compared to all the other 7-rib models (both bigport and smallport). This correlates to the 3-rib bigport cams having more lift.[/quote']

Cheers Hiro and Sam

I'm still learning which forums out of a few seem to be more informative than others so i can not double post in different forums

Clearly the other one is becoming number 1 at this point.

[justin_es]

thats for the 232 cam obviously.

 

cheers.

There's nothing wrong with posting the same question across multiple forums (at last count I'm on 9 different Toyota forums), and plenty of people here have knowledge/experience with 4AGEs. Yes Toymods probably has a larger knowledge base than here, and Twincam more experience with the FWD 4AGEs, but doesn't mean you should discount Rollaclub.

[justin_es]

Out of the 4 I'm using at the moment rollaclub is one of the more informative ones. Definately not leaving any of them out.

 

Tocau though seems to be very sportivo dominant and no one is interested in the old rollas. With the exception of yourself that got me onto all these other sites haha.

 

Cheers.

Yeah, TOCAU is very ZZE/ZRE Corolla and XV40/XV50 Camry/Aurion based, but there are a few that lurk around with knowledge of the older models. Not that it's a bad forum though.

 

And if you think there's not much love for the AE9x on TOCAU, there is barely any love ANYWHERE for the AE102 (except AE101oc) :P I'm the bastard orphan child of the Corolla world, too new for the old-skool sites, too old for the new crowd, and didn't have a local 4AGE model for the Twincam crowd.

[justin_es]

haha. regardless of where your generation lies you seem to have alot of knowledge about them all haha.

 

i used tocau heaps when i owned a sportivo. so i already knew how sportivo strong it was but yeah back then i always saw threads pop up about older ones. not so much any more.

 

i have to say (completely different car here) the best set out forum i have ever used has to be the street commodore forum. and no not because i love commodores (well as of last few months i have strongly turned away from holden/ford) I'm purely talking the way the forum is layed out and looks etc etc.
