this is for a friend. Got a 20V silvertop,what can be done SIMPLY to add extra HP, can you change the cams in them to some 272's or something with stock ecu?
tellme how to get this motor screaming with the stock ECU for least $$$ possible without using NOS

i dont think you can upgrade cam without ecu upgrades on a 20v
vvt interferes i think
unless you turn it off that is..
afm or map ?

thought all silvertops were AFM? whioch would mean larger cams would be easier to use on the stock ecu.
switching VVT off isnt too much of a drama i spose.

If your gunna to do that, they're worst than a 100Kw.... don't know where people get the Idea from... only way to get more power from these is rip the head rip, port, shave... if you want cams, well you'll need and A/M ECU to advance them at a different rpm. Tried and True method. Decent cams for these also cost $1100, not incl cam gear to dial them in properly

exactly! VVT is there so that at LOWER rpm you have MORE torque and power!!! without VVT, it's just a cammed 100kw with an extra valve and quads. low-mid range will suffer..
the 20V's already have pretty good torque (ie close to as much as possible) so abotu all you can do is move the torque band upwards and get more POWAH...
as Johnny said:
exhaust, air filter, then expensive internal mods.
or turbo

very nice cams.... I use the 264 9.0mm IN/EX, but a standard S/T they made bugger All difference til we did the head work.... Truefully, We get B/T and S/T with Microtech, Pulling 115-120WHp, just with a port, shave and a well setup exhaust system, standard bottom and cams.....

correct
and no (omg this thread is old) but 20v's came in 2 formats
earl;y and late
early ones had AFM
older ones had MAP
the older ones werent AE101 sedan's tho
they came in an ae101R wagon released in 1995 (yes the yeaf of release of the blacktop) and nothing else
these waghon engines are rumored to be the basis of the TRD group a engines.. having SOME ae111 parts and SOME ae101 parts
so that answers simons question (if somewhat late)

Hey Jonny, How much do you shave off the 20v heads what sort of Microtech. I have 20v in corolla 4wd wagon. Wahoo

one the Blacktop, nothing, just a clean up and a TRD 0.8 mm gasket and the Silvertop, very little ( 1 thou max) and the same gasket (TRD 0.8mm). But it also depends on fuel. As for the ECU, any aftermarket one will do.

Which engine are you talking about? If it the B/top,Yes the AE101R wagon did come with it as this is where I got mine from; BZ touring and also the GT sedan... the Hatch was quickily phased out by 1995 as it didn't sell for some reason and never got the late model 20V's

Not 100% sure, but just get the ones to suit your engine

|
Yes, but very not a great amount

Depends on lift duration and redline. Any different cams will need the correct shims, but some will be fine with standard shim etc. Clearences will always need to be checked, and unfortuately, this will be after a dumby fit.

Talk to me in a few more weeks as this is exactly what we are doing ie Blacktop Cams, Throttles and manifold on to a S/top. So far I haven't heard any thing about this setup; only B/top on B/top or S/top on S/top. I'm just lucky that I have a couple of each sitting around and with a S/top currently going into the rally car for next year's comp, this would be the best time to find out. First run is going to be the standardish setup's that are outlined above, then we'll fit the B/top gear to the same engine and see what the dyno tells us, and it should as the B/top cams are a have more lift and more duration then the S/top's, so this should give some changes. The throttles, well, I think that they won't make the greatest of difference, but it'll be worth seeing anyway.

it would be awesome if you could do that Johnny, it would lay some debates to rest for sure. Also I though it was only the intake that had 0.5mm more lift on a blacktop and a 5 degree later duration.

You are right on that, exhaust is identical to the silvertop. I keep forgetting it's another engine that where running identical cams with higher lift,(256deg 9.0mm lift in/ex) this is going into a Brand spanking new rally shell...GARC here we come
