Exhaust Cam Gears

[duh!]

Guys... anyone here changed their exhaust side cam gears before? What are your feedback on this mod? Is it worth?.... do let me know....:regular_smile:

Unless u r running a turbo or SC, i doubt there would be any significant increase in performance on a NA engine .

Anyways, how do just 'change' the exhaust cam?!Do u mean re-grinding it?Pls enlighthen me..:shades_smile:

 

[duh!]

http://my.is/forums/showthread.php?t=243053 is a nice thread about cam gears, discussed in IS forum.
http://www.mvpmotorsports.com/Templ...=361&SearchYN=N is a list of cam gears available. Again, these are all for IS300 specifically...
I was thinking it may apply to Altezzas too.... well.. I did a search, and found a website selling it... but not sure about the gains in our car... hence the question... comprehendo?

duh,

thanx for the links. Btw i got the cam gears mixed up with the camshaft earlier (was half asleep during my earlier reply..hehe). Just realized u were talking about pulleys...


Back to the topic, i'm not sure on whether the camshaft configuration (as in ilnlet and exhaust) for the altezza and is300 are the same or not.The altezza runs on a 4-inline (dual camshafts= each shaft to 2 cylinders i think) whereas the the IS300's 2JZ runs on a inline-6 set up. There's a huge difference there.

However, if ur concern is on pulleys for 3sge, i think there are at least two forummers here with aftermarket ones. never got to ask them on the benefits...i wonder if they are still active forummers...poro?:regular_smile:

 

[duh!]

Dude... I think this cant work on our cars lah... I got a reply from the Australian forum... so.. gotta ditch this ... hehehehe.... now.. thinking of what to do next.. hahaha...

You are discussing about adjustable pulley and High cam? Need Sifu here to explain..poro san, Encik Jahax?? Stepyew??? JayD...hello...

 

[duh!]

I'd just drop this discussion seriously.... its no longer the path for me.... unless one would one to meddle with all the crazy hassle of settings and timings on the intake cams... and totally (perhaps) disable the VVTi.. which is a waste.... hhmm...

 

[JaHaX]

disable the VVTi ... then install Toda oversized piston, adjustable cam pulley, valve spring etc ... and the icing on the cake is the HKS V-Pro ... sweet ...

oh ... then istall the Toda 4throttle system ... double sweet ... 250 HP on crank ... 210 Hp on rear wheel ...

kick in the arse man ... oh mind u ... burn ur pocket also ... hehehe

 

[duh!]

N.A mods... as usual... exhausting and expensive... that is why I requested to drop the discussion altogether... heheheh.... I think one of the guys in Singapore tried the 4 throttle system.. did not know how it went.. but I know it was removed not too long after that... dunno why...

 

[JaHaX]

as jack black said ... "u are not hardcore, unless u live hardcore" ...

thats the price u need to pay if u wanna be different than the rest ...

 

[JayDM]

duh, wise move

test, hello bro

jahax, dont abuse the engine..btw, whr u got that part combination?really can churn 250hp?!:confused_smile:

 

[JaHaX]

Jay Dee ... the calculation is on a conservative mode ... actually it can go up to 275 hp on crank ... hehehe ... and still maintain NA

we are talking about TODA oversize kits here dude ... which will bump the displacement up to 2.2 cubic capacity ... and all other shiny stuffs from TODA ... and blueprint/port-polish the engine

and mind u ... we are talking in the region of 50 grand poorer dude

 

[duh!]

50k RM for all that...talking about hardcore.. hahaha

 

[JaHaX]

a crazy hardcore to be precise dude ...
