i still dont see why people are crying for tc cams when we dont work on lift were cams would be appclicable.. we work on timing....

power VS money your better off getting an EMS and tunning your car to perfect the fuel and vvti timing controls... this is VVTI not VVTL ppl..

This isnt a 350 chevy that you can push 500hp out of easilly NA, it is a small econo motor that is already nearing its peak operation as far as power output, so boost is the best way to go. The NA build would be a fun experiment, and should yield a nice power curve out at the end. Not to mention having a rock solid motor.

Maybe someone will come up with some good NA cams for it. .who knows. And that would be cool, but most likely still not worth the small gains for most people, other than those of us who enjoy building it as much as driving it.
If I want to spend $10,000 and have a car that burns through tires until 3rd gear and may blow up at any second, I'll buy a turbo. And, I actually may!
But right now we are discussing cams and people who are interested in cams.

No, your not going to make 500whp. You aren't with a turbo either and don't try to compare this to a 350 chevy....

You still haven't shown any proof of what cams do for a TC, just made a lot of assumptions. And you still haven't told me who tested them and why they don't make power or are worth the development.

No assumptions from you, I see. It is proven fact that all turbos on the tC blow up and cost $10,000. Good to know

People do not know how small of an engine it is. When they picture an engine they dont take into consideration (mentallY) how big a few ltr's is. this is verrryyyyy small ....but when adding FI into the picture you can make some sweet power.

i put it bold and some flashy neon colors this time so more ppl would read it and not skim over it..maybe ill put some LED's or blinky things to make that statement more appleaing for ppl to read.

IT doesnt matter, pete... people still think this is a honda Granted having more lift across the board would be nice, but not significant given our displacement and everything else in the picture (including price). And if you mess with duration at all you will have to visit the realm of messing with the VVTi control to get it tuned correctly again.

And tcengel.. I just said it ISNT a 350 chevy.. I wasnt comparing it to one... quite opposites, at least in the english language :p And I also just said that in the past, shops have talked about why the DID NOT BUILD AND TEST ANY CAMS. So why do you keep asking who tested them???? Is there a comprehension issue here? ZPI was one the came out talking about it and decided later to only produce FI cams. I honestly cant remember the others, since it was ages ago in one of the other million "anyone got cams?" threads. Others of us have realized what Pete and I have already stated. No one is saying they wont produce power, but the simplified view that you will just spend $500, slap em in and gain a magical amount is ridiculous.

And again, you sit there and assume your bolt ons match those dynos you keep talking about, which is ridiculous as well. For one, you dont know who ran the dyno, the other variables involved, the before and after comparison, etc.. and any dyno from the manufacturer themeselves can be taken with a HUGE grain of salt. So again, you havent dynoed yours.. .but assume it is making X hp and you just assume that the mid pipe got you another x amount of hp.....

Now who is making assumptions????????

Does anyone know if the Brian Crower cams will be for N/A or F/I? Also I know that cams wont make a great gain our car, but I need posts so I that I can post in the classifieds section. lol

Cant make 500hp with the 2az with forced induction?.... um tell Kenny Tran that!!

Honestly, if you went and were to look under the hood of Kenny Tran's tC you'd probably see that they disabled or even completely removed VVT-I.

I imagine that a car with Horsepower like that; you'd not leave any amount "Variable" timing to the car. believe you me... they have FULL control of their timing, with numbers like that you NEED to have full control of the timing.

if you the ability, REMOVE VVTI. it's not worth the little amount of power you get and increase the chances of jumping timing on a high horsepower application.

since vvti is controlled on the intake cam would messing with just the exhaust cam affect vvti? reason im asking is because if you read the description for the ripp mod cams they only mention the exhaust cam, nothing about intake. im assuming becuase no one wants to mess with the vvti... and if all they're doing is a regrind on the exhaust cam $600 is a bit much imo

I'll try to re-summarize what others have already said:

The 2AZ-FE motor is NOT built for mad power with a few bolt on parts unless you go F/I. You will have to almost rebuild the entire engine from new pistons, rods, intake manifold, intake header, port and polish, and much more to get 'mad power' after a very good tune from e-manage

Emanage is for cheapo's, if you are already spending 6K+ on your motor then you need to go with a standalone unit inorder to manage all the power a built motor. don't piggy back that thing. its not a good Idea.

Again, are you going to enlarge the hole in the intake manifold? If not, you really arent getting much of anything out of a larger tb. From what many others have found, the hole in ours matches the stock TB hole, it is not larger. And I forget who, but there have been oversized TB's for the tC for a good while now. But again, not going to do much with the stock manifold.

And if someone is building a racecar, they typically dont want vvti, vtec, etc on it. Those things are great for allowing a bit more power while still keeping the car economical and emmision friendly (that is the purpose of those.. along with the egr function vvti brings to the table, eliminating a stand along egr). But if you just care about raw power, just build for it and forget those systems. There are advantages of having a good variable timing system in a high powered car, but for what yo ustart with on a typical vvti or vtec (and no, the two are not the same thing) system, a racecar is better off built to be a race car, not an eco friendly sometimes racecar

So in other words, if you want a built motor... don't even start with the 2az-fe...
