20 Valves really that bad?

[~SlideWays~]

My butt dyno tells me that my mates blacktop pulls much better than my gf's silvertop.

The silvertop feels flat all the way through, almost choked. Whether this is because of the AFM restricting or that it needs a tune I don't know. Its a very healthy low k's engine though, I've just always been a bit disappointed with it...one day she'll let me change a few things

Very impressed with the blacktop, although the silvertop isn't going to throw a rod out now is it

[Mr Revhead]

yeah damn straight the BT should feel faster!

throw a link on it

[skoty]

Prehaps the 5 valves/cylinder was an over kill for toyota? I mean it's not very common in other performance engines.

:roll:

20v's have there place hate them or love them... they turn the wheels around...


mines not to bad power wise but I wont say that coz ill get flamed for saying its quick

yea but ures is quick lol

[frost]

has anyone tried using a vtec controller on vvt? say apexi vafc.

i was reading my neo install manual and it hooks up just the same as vvt, how about the signals? what voltage does vtec use?

[Mr Revhead]

that would slow it down

VVT is not like VTEC..... having it switch at one point constantly is pointless.

also, its on most of the time, and they run real flat with it diabled

[AceSniper]

vvt runs best when switched off after 6200rpm area, silvertops keep it on till redline, blacktop drop it sometime b4 redline.

fuel and playing with vvt wont really change power, My thoughts are its all in the advance... and to do it right you need a aftermarket ecu.

iv found that the "usual barrage" ie pod filter, silly exhaut/fartcan
actually looses power in a lot of cases

Not for me. At Chequered Flag the typical "stock" one made 77-80fwkw, the ones with exhaust etc made into the mid 80s. Loudtoys freak cracked 90 if I remember rightly.

[Mr Revhead]

depends on the exhaust.....
a 3" pipe and cannon prob wont be as good as a stock system with improved 2-1 section

[Cakky]

my mates have both been dyno'd

one with good exhaust and trumpets made 135hp ( on nzefi dyno i think user gasman on these forums ) and another friends with exhaust and airfilter made around the same on CF dyno

Or 2 1/4 from headers back with one x 3 inch cannon style stainless jobby that actually did make it a lot quiter than say having no exhaust from the headers back . Pods can give you quite a good gain provided they are done properly i got 4kw from mine alone.
Car was making 85kw atw when i got it, stock standard and had only done 60k. When i sold it at 184k was making 94kw atw, had exhaust and intake and i think 2 deg - timing. Regular oil changes, cam belt and water pump was the only maintainence.
Still see it drving around in palmy every now and again.

Mine runs a cam/vtec controler, but it's able to turn it off as well at high rpms, or at least I think it can, it controls my fuel too, so I'm not playing around with it

I think the 20V should of had a forced induction model, mine goes pretty well, at the end of the day it is only a 1600.

I've never driven a n/a 20V, aside from around the block, and I'm not really the type of c**t to rape a customers car. So I can't compare mine to a standard one.

Would love to give one bit of a poke one day, but the 101/111's just don't do it for me. Give me a coversion in a 82/92 any day

[bluemaumau]

does anyone think toyota would have got similar results in they had stayed 16v?

with or without ITBs

[Lanius]

Brilliant, tough, reliable little engines with good power for their capacity. Might not win any Bathurst titles any time soon, but anyone who discards them as rubbish is an idiot

Having said that ... I'll agree with Lith, B16a > 4AGE

When did I say that in this thread - did I subconsciously blurt it out???

Edit: While I agree with that comment, you'll find Si is who made that statement

[Blackstripe]

I like my 101, I am probably one of those "first time performance oriented car owners". But I can notice its sluggishness when compared to my previous car a bluetop fxgt, the 20V is much less torquey down low and the gears feel like they are way too long.

Its also very unpredictable, sometimes it feels pretty damn fast with VVT off and sometimes its sluggish as hell with VVT on (And vice versa). I think Toyata screwed up the ratios, the third gear should have been way shorter, as it has lead to a many unsatisfied quick pullout. Havin said that in 1st and 2nd gear it brakes traction easily which is why the long third seems so out of place. It also feels like it takes way too long to get to 8K, (When not in first) and doesnt really need all those revs (Unless your in first )

Moral of the story I think is, although the 20V engine alone is inferior to expectations, coupled with a slightly heavier-than-usual car and weird gear ratios gives it a reputation far worse than it deserves. I need to buy a 20V AE82/92 to test my theory lol

[AceSniper]

Blackstripe : find a c56 they are slightly better ratios

[the fallen303]

20v as a daily is great, cheap to run, peppy enough to have some fun, and just a nice car all round. if i want to drive something angry, i take out the jz

[AceSniper]

something angry, i take out the jz

Bring it... 20v challange

[B1NZ]

There seems to be too many people using the seat of the pants dyno when comparing the 20v to the 16v
