Hay guys did a whole heap of searching, BUT, would ralliart cams on a TL with all the breathing mods help much. I have an offer for some cams CHEEP and was wondering if it's worth it, or save a ****load and get STAGE 1 or STAGE 2 cams from RPW.

Would a stock computer run Ralliart cams and others,

Any other info greatly appriciated.

I believe that they would offer something.... teh ralliart cams will also affect your lifters in the long run as well as possibly causing further engine damage if left on open throttle for a long period of time ( which you never would do unless you are nuts hehehe ).

Look at it this way, if they are costing you bugger all then why not. I knwo if i got soem cheap i would be putting them in.

its not cheap to put cams in and out of a magna as you have to take the heads out. if your not doing the install yourself it could be expensive. if you have a mate in the business and your set on getting this mod done, why not get someone to clean up your heads while they're out with a porter to get more and smoother power.

just a thought

just a thoughtYou can actually swap cams without removing the heads, so long as you don't want to change anything in the valve train at the same time.

Regarding Ralliart cams, as I see it the power difference between the Ralliart and the VR-X is 17kW at the fly wheel on paper. This comes partly from cams, partly from increased compression, and partly from mild head work. Just installing the cams without the others will only give you a fraction of that 17kW, so unless the cams and the labour is going to be really cheap you don't stand to gain that much from it. :doubt:

However, don't let that stop you :D

I would be doing the work myself, i have done numerous engine rebuilds and yes you can change the cams without taking the heads out. Simply put in some compress air into the cylinders. I also have a mechanica frend who woudl do it for a carton of beer.

HUMM good points though, so how much of the fraction of power increase would i get 5kW.

As for the lifters getting damege, they shouldn't, same part number for ralliart and standard magna.

In regads to computers, would the stock computer compe with the new cams, seing as it would breathe more air?

Any other thourght?

The stock computer will be able to run it and you will see some gains from it, but to get the most out of the Cams, you will need an aftermarket ECU installed and tuned.

how will the ralliart cam affect the lifters???? the lifters used in ALL 3.5ltr is the same including ralliart :doubt:

Ralliart cams and lifters are hardened differently, so by putting the hardened ralliart cams into stock 6 the lifters wear alot faster

Autospeed (http://www.autospeed.com/) interviewed someone from MMAL a few years ago about this kind of thing. I think you get an extra 8kW from adding the cams on their own. Of course this will be more with headers, improved inlet manifold, etc.

I'd definately recommend a piggy back, though.

humm 8 kW hardly worth it, i think i might save up and get a nos kit. LOL they are only $600 for the US for a 100Hp shot kit.

I think i will concentrate a bit more on the suspention and breaks at the moment.

thanks guys

I agree with Brett, I think it goes quite fast enough already wogs, therefore, no more mods allowed LOL :bowrofl: lol

On a serious note though, after some of the things I have read about on this forum in regards to people changing cams, I would be very careful. The instances where people have put in new cams to find their engine rattling like a truck I think is more than coincidence. Personally, If I was going to do it, I would be looking at rebuilding the heads completely with upgraded components. Also, if taking it that far, might as well get it ported and polished at the same time and throw in a piggyback ECU to actually take advantage of the different characteristics of the engine. Just my 2 cents :D

yeah well i think i will wait and get some cheep heads and rebuild them with new cams so i can simply drop them into the car and go.

thanks guys

but the lifters are the SAME they didnt use special ones in the ralliart.if this is so than all ralliarts will have to replace there lifters :nuts:

No more mods allowed my asss. Just excatly when does one have enough power.

I'm going to be fitting barrys fuel rail kit in Feb allong with a groud wire kit aswell, mainly for better throttel response and stronger spark, allong with a voltage stabaliser.

I have found some heads in a wrecker, but a littel to expensive.

BUT i have started to design my new intake, with dual runners of different lengths. something like this.

Should be good. Got to calculate voulem ect and length so i can get the resonance frequancy right ect. BUT it should work. LOL, Famous last words.
