Under preforming 20 valve(silver top)

[AE86_4life]

I am a little concerd that my 20 valve is under preforming, I was wondering if any1 who has a silvertop can give me an indication of what kinda pwer i should be expecting. When i rev the shit outa my car like 7.5 to 8K by second gear ive just touched 100KPH if that helps refrence anything also i am running a 3.9 ratio. Also i dnt think my VVTi is working i took out the plug and put out the same power i dnt feel a change in the reves either when it was pluged in.

Ur help would be much appretiated!!

plug in the vvti it will make motr run better

and change ur diff ratio to a 4.3

ull notice the difference alot

and get a lightened fly wheel

they you should be happy


and maybe a new ecu too

<div class='quotetop'>QUOTE (AE86_4life @ Feb 27 2008, 02:28 PM) </div> hey the info you have supplied has nothing to do with power..... all your giving is revs of engine compared to final drive speed at the tyres.... power would be more comparable in regards to HOW it gets there...

if its a silver top you should have a definate kick at about 4grand ( i think thats the cross over, i could be wrong but on silver tops its a fixed value)

Check basics like ignition timing, spark plugs, lead, coil etc....

Retarded ignition timing will not the power out of a 20v....

Sorry 4 tha lack of info Guys but i should also mention I have an aftermarket lightent flywheel TODA on i belive, I also am running a A freedom ECU with individual coils. So fixing things like ign timing isnt as easy as rotating a dizzy lol but Thanx alot guys for the help

I was concerned about this too... mines using stock everything but running a little rich. been getting a mate to time me on the freeway, i get on average between 7 and 8 seconds zero to a hundred. i can't get it any better then that.... i hope mines at least close to being a good 20v st.

Friend of mine was complaining about lacking performance out of his 20v ae82 also... Ended up doing one of them 'tee-kay' tests and found combustion gases in the cooling system.

Just a thought.

is that you Anton?

is that your engine in your avatar pic? if so you need some trumpets and a tune on that ecu, most likely a change of ecu all together

i was very pleased with the power of my 20v

i have a w58 and 4.1:1 diff ratio and i will get around the 120 mark out of 2nd and 190ish out of 3rd if that helps at all, engine is stock with microtech and trd 0.5mm HG
