Info on my Webcam 5sfe Cams

[mrturrari]

I received my Webcams in the mail a couple of days ago and thought I would share some of the info I have gathered during the process of ordering them. The grind I received is a slightly different one that they felt would be better for my setup. I may end up wishing I had gotten the 101 grind but we'll see. It's the 763 grind which looks very similar to the 294 but slightly less duration and more lift. Here is what I have been able to measure on them:

Webcam 763
Intake (The exhaust cam I am told is the same as the intake cam)
Lift 0.351"
Lobe centers 110*
Duration @ 0.010" 264*
Duration @ 0.020" 240* (Verified with Webcams)
Duration @ 0.040" 224*
Duration @ 0.050" 216* (Verified with Webcams)

They were also kind enough to give the specs of the 96 gen II stock cams used to make these. These should be the same as all 93-99 5sfe's.

Intake
Lift 0.0316"
Duration @ 0.010" 252*
Duration @ 0.020" 218*
Duration @ 0.040" 200*
Duration @ 0.050" 194*

Exhaust
Lift 0.0319"
Duration @ 0.010" 272*
Duration @ 0.020" 224*
Duration @ 0.040" 204*
Duration @ 0.050" 200*

I also attempted to measure some 91 cams I have lying around but with the smaller lobes it is more difficult to be exact. Probably a margin for error of +/- 4* but don't quote me on these as they could be way off. It does give a ballpark though.

Intake
Lift 0.289"
Duration @ 0.010" 256*
Duration @ 0.020" 224*
Duration @ 0.040" 208*
Duration @ 0.050" 204*

I was unable to measure the exhaust cam because it is not possible to put a degree wheel on it while in the head.

Good info, thank you for posting. What needs to be done to put these cams in a 94 head? Are they plug and play or do I have to change anything? What was your total and when do you plan to run these and are you going to dyno? Thanks

is 050 the standard measurement of duration? most cams list a duration, and then duration at 0x0.

the rated 216 at 050 is still a mild cam. should be much better, but im still dying to see someone run a hot cam set.. i really think the head will do it.

you'd need huge shims to put them in a 94 head.

The grind is independent of the cams so the same grind can be made for 91-92 cams or 93+ cams. These I have are the 93+ which will only fit the gen 2 5sfe, 93-95 MR2s, so yes they will drop right into a 94 head with just the normal shim adjustments. Fitting them may require a couple of things. One, you need to check coil bind on the valve springs to be sure you have at least 0.0360" of travel in them and if you don't then you will need new valve springs. Second as with all new cams they will need to be shimmed although you can probably use some of your existing shims because the base circle doesn't change with welded cams.

Total was way too much... about $650 after all the shipping and everything. I went directly through Webcams though. If you are looking for the 294 or 101 then places like http://www.importperformanceparts.net should get you a better deal.

Different manufactures measure differently so it is really hard to compare unless you can actually measure them. Advertised duration can be at 0.001", 0.010" or 0.020" so that doesn't tell you much and companies like HKS give you that plus 0.040"(1mm). Most American companies will give you duration at 0.050" which is probably a better indicator of actual flow duration as the valve is open 1mm at that point.

Yeah these in my book are still on the milder side of things but probably a little hotter then a 294 because of the lift and ramp. They seem to have similar specs to the HKS 264s put in the 3sgte, 224* @ 0.040" and almost 9mm lift. Then again the 294s have a similar duration at 0.050" and those don't move your power band nearly as much as with the HKS 264s. I guess we will see when I get them installed. If I don't like them then I can always sell them and try again.

you'd need huge shims to put them in a 94 head.

These are gen 2 5sfe cams so they use normal shims that you get from Toyota. One of the reasons I went with Webcams was that just grinding a set with this much lift and duration on a 93 would require some really fat shims. Those who have 91-92 heads have it much easier since you can grind down 93 cams.

also, apparently late model rav4 cams are HUGE and can be ground to hell. oregon camshaft recently ground some cams for a guy with 9.0 or 9.5mm of lift. he had a 91 head and they tried 93 cams, but they fell short. the rav4 cams had the extra meat.

[mrturrari]

That's strange... are you sure they were looking at 93 cams? These cams I had done were reportedly from a 96 Rav4 and they are the same as the 93s. Also the part numbers show the same for 93-95 MR2 5sfes and 96-00 Rav4 3sfes.

thats what oregon camshaft said.. sounded weird to me as well ill try to get the guy to chime in.

I have seen those but it says that they are designed for the 92-95 5SFE engine, is that a typo or are they actually different? Can I use them in my 91 5SFE? I have been thinking about getting those and rebuilding my engine for some more power.
