camshafts specs and all the info


OK, I'm making this thread because i feel like many TO.COM members
may not be 'up to speed' when it comes to camshaft information.

The info which follows may help in selecting the proper profile(s).

You're probably aware of the people, stores, and sites claiming they
sell some type of cams.

A while back, I was trying to get some new cams for my new crazy
ass set up (lol) so, i contacted Speedvision, Toytunning, and
Starletgtturbo.com.uk and asked each for specs on their respective
cams.

I asked for the advertise duration, the actual duration @50 thousand
and the valve lift , also what type of material (regrind or billet).

Speedvision's reply: 265 degree duration both intake and exhaust,
8.0mm lift both sides, billet material made from scratch, not in stock
(still in the testing) for around $500.00 (USD) per set. I was never
told the actual duration.

Toytunning's reply: 254 degree duration, regrinds and also, no actual
duration numbers.

Toyotagtturbo's reply: No specs at all.

Now, please read the following information carefully:
There is advertised duration, actual duration and valve lift.

Like car makers that always list flywheel HP and not wheel HP
(because flywheel HP numbers are always higher), the three
camshaft seller also only push their advertised (higher number)
duration... BUT, what about the actual duration?

Now, check this camshaft shop in NZ <- Clicky
(scroll down until you see the 4EFTE specs)

What I have in my car at the moment are the stage 2 cams but the
ones I'll soon be getting from Web Cam, will be stage 4 cams
(but, enough about me.)

If any of you try to get the so called "265 cams", please don't waste
your money. While the 'lift' is a bit different, but the HP gain will only
be around 10 WHP. Probably not worth the money you'll be spending.

For a better understanding, do your homework on cams, durations
(advertised and actual).

Denys (boostjunkie)

PS: Keep in mind, the duration that counts is the actual duration,
PS: NOT the advertise one. Always ask for the actual duration.

Wow stage 4 cams from Franklin Cams

in Canadian is only $405 plus shipping. I know that is going to be a
whole hell of a lot cheaper than getting them from Webcams out of
the states! I'm going to have to call them and see what shipping is
going to be.

Denys I said as much in a camshaft post I made a few years ago but I guess that must have been deleted like other good info that we had around here.

How does the 292 do in a street car as far as driveability? Does it give issues if you stop for a light on a hill? Or a stop sign? What rpm's do you normally take off at?

To keep the car idling, I have the idle set around 1400rpm.

Sometimes I can get it down to 1200rpm but it wants to die... I've had issues trying to get it to idle...

BUT I have fueling issues as well. I NEED to trim fuel at idle and cruise....

The cams are just starting to "open" up as I call it at 7k!!! Rite when I have to shut it down.

That's what I had been told about the 292's but wanted to hear it from a Toyota owner. For my 3s I got the 272's for streetability. Even with these I've been told to increase redline to 9000. The turbo is spose to come online at 3500 and the cams at 4000. For the 3s they say turn it over 10,000 with 292.
The funny part to me is 292 was considered a moderate hydraulic street cam for big block MoPar. I have a roller cam laying around with more than 315 duration and it's a street cam also.

the DIS cams have the weakest profiles of them all

the best stock cams are the ones from the 5EFHE

the performance increase is marginal compared to stock imo

significant increases are only noticeable with custom grinds

so is it confirmed that the 4efe 4efte and 5efe share the same profiles. Ive tried both4e & 5efe using all manifolds including acis. after a 4year gap Im back and plan to use a 50mm 4afe tb on the corolla tubular manifold, I just need to finish the 45 to 50mm gasket. I burnt out my rpm switch although im now in a low rev auto so so acis is on the backburner. love the site lads, some great info and theory

i'm pretty sure the stock 4EFTE, 1st gen 5EFE and the 5EFHE come standard with a 50mm throttle body

the 2nd gen 4EFE and 5EFE motors use a 45mm throttle

so you wont have to go with a 4AFE throttle body if the plan is to go 50mm
