4AGE cam talk.

[Nuty|Mike]

so if i put bluetop cams in my red top tvis ill get uber more fwkw au bo ?

[RedMist]

Interesting. I thought for compressed engines you hairdryer and impeller boys went for shorter duration cams. I suppose its boost dependant, the higher the boost the shorter the duration.....

Don't ask me.. I'm an NA man!

From what ive heard its:
bluetop = 240
redtop tvis = 240
redtop = 232
any gze = 232

I think ants means any NA bigport has 240 degree cams.

A lot of guys running big snails also go for bigger cams, 264 or 272 being the norm. But they set them up with less overlap than we NA guys do.

[Mr Revhead]

well according to Toyotas own info its as stated in the first post.

that is bluetops have one cam. AND ALL OTHER 4AG(Z)ES SHARE THE OTHER.

Its the overlap to stay away from if i remember correctly, not necessarily the duration

what i recon would work good is the bluetop n/a cam inlet and keep the standard gze cam for the exhaust (for forced induction). This in theory would work good..

yep seems to do the trick eh

[thaphatty]

when i put some bluetop cams in FLAWLES'S gze it got a further 3psi over its usual 12 = 15psi.

im not even gunna go into why that was

lol, yeah.

Wanna make it boost even more?
Just crush the exhasut so it is 1/2 blocked.
That will increase the boost in a superchaged 4AGZE too.
( but wont help performance )

Also trying to see why this is?

With less lift and duration, the red top should make its power at a lower RPM than is rated here? like the GZEs rated max power @6400rpm. Is that right, cams can effectively shift power up or down the rev range. Then shouldnt the crappy redtop make its power at slightly lower RPM If it indeed has the smaller duration cams.

With like the GZEs rated max power @6400rpm

But obviously toyota state differently to what I think here.

[ants_ae92]

Also I have an oddity that maybe Mr Revhead can explain?

I have a 1987 ae92 levin with a big port tvis. It has red top big port head and intake manifold but a 3 rib block? Did toyota ever bring out any thing like that in description?

[Mr Revhead]

maybe as chaos said, using last of the old stock.
effectivly the same engine as the block doesnt really effect anything

can you send me your full model and frame numbers?

i cant tell too much about the blocks from the epc as there is a few other changes as well. but i cant see anywhere the ae82s sharing p/n with ae92

[ants_ae92]

Yeah I will pm you my full model and frame numbers tomorrow morning.
