Cams? Options

[yfn16]

It's been a while since I've done any work to my Celica, but I'm getting ready to tear down the motor again. Does anyone know if there are any companies making cams for the 5sfe? I know years ago you couldn't find anything. -Thanks

Webcams:

now the real info



now my motor has 156K miles on it and my compression was low, but consistant.

here's a comparison was another 5s, 1998 51K miles on it



and some #s info



and the INFO

my 5s topped out at 123whp and 126ft/lbs of torque.

on the 1998 stock 5s (intake) at 4700 RPMs it doesn't make any more power, it drops hp like a rock. My 1995 156K 5s continues to make hp. I peaked out close to redline and CONTINUED TO MAKE POWER until then. So at redline (about 6000 RPMs) I had about 123hp while the stock had The stock 5s 103hp. As for torque, the 98 drops off at 4700 and mine continued hold out longer. I had 110ft/lbs of torque and the stock 98 had 92ft/lbs.

The bottom line is I didn't dyno my car before the cams were installed so I don't know exactly were I'm starting from. From the research I've done they seem to average around 105-110hp to the wheels. If my motor was in peak condition like the 98 then I have gained about 10hp to the wheels. The important thing here is my car now holds the power later in the RPM band and where any other stock 5s drops off, my car continues to make power, right to redline.

now when I turbo...

Colt Cams:

i forgot my thumb drive, so ill have to go back to get the runfiles to be able to overlay the runs, but just by the numbers, he made 135whp, uncorrected, and ~ 140ftlbs IIRC. he has some printouts that im sure he'll post later tonight when he gets home.

dustin made ~123whp with the webcams, but the powerband is quite diffrent between the 2. the coltcams are definetly smoother, with more overall gains, where the webcams were much peakier, with all the gains coming above 4K rpm. once i get the runfiles, ill be able to illustrate this much better, with more details.
for now, i will add a pic i took while tuning it at the dyno.
it shows 2 runs.
the blue one is when we first got there, without any tuning, the red one is after a handful of runs of playing with the SAFCII.
blue run = 115.16whp, 131.06ftlbs with STD correction.
red run = 128.61whp and 140.17ftlbs with STD correction.



goes to show its definetly worth it to pick up and dyno tune a SAFC or somthing after mods like this..hell, even stock you can probably gain 10-15whp from an SAFC by leaning the fuel curve some.
enjoy zac!
