I gained throttle response and (admittedly subjectively) a little bit more torque even just with a TRD axleback exhaust (obviously no ECU tuning). I accept I could be imaging it but I don't think I am. If there is any more power though I wouldn't think it more than a few hp at the very most - probably more like 2. But it was more the throttle response that I really liked about that modification.


But for a serious gain I agree with what you say. Here in Australia we have a production Toyota 86 Racing Series and the cars are remarkably similar to showroom stock. They obviously have to have significant modifications related to safety and the brakes are upgraded but so far as the drivetrain is concerned, the only mods are the exhaust (from headers all the way back) plus an ECU upgrade. The intake including air filter is 100% stock. It was explained that the two upgrades (ECU and exhaust) had to go hand in hand and if they didn't, it just wouldn't work at all. The competition cars in this configuration have 179 kw flywheel output 7,500 versus the stock output of 147 kw at 7,000. Torque is also considerably raised lower down - up to 246 nm from 205 nm.


Granted the 1.8 Corolla engine is not the 86 engine but it is still a normally aspirated current model Toyota and I think the same would apply in that to get the maximum out of a new exhaust, an ECU tune is necessary.

Anyone installed or will be doing these? Have any input? As they're on my list.
You sure have a knack of finding aftermarket parts I'd never find in a million years of Google searches! Well done!
Thanks! I try not only for me but for everyone else who may be looking into doing modifications as well & may not have the time.

Pulley Kit doesnt do much for a stock tuned car....You might be actual hurting the motor...since the pulleys are lighter etc..

When I had my 1st Gen tC....I bought the NST Pulley Set.....After reading reviews of others having issues w/ the motor I did not want to gamble using this...I sold it off.

~I honestly feel that as a negative statement.. Like saying don't remove the carbon filter because of so and so (which I hear that carbon filter will also be revamped anyway) or don't do this exhaust mod because of back pressure etc. Honestly most that report bad news are those that floor the vehicle, beat and don't maintain them like they should. Which I honestly will not be doing 247 as it is a DD.. I've got fam & friends running N/A mods such as this with no problems as they do care and maintain their cars only doing short bursts to pass traffic etc.. Being as it's only the Crank Pulley it is light it will then lessen the load for the motor to work freeing up Hp that the heavier CP would hold back others on Toyota Nation and other forums have been happy with this mod as it did give better response.. that harmonic stuff imho is irrelevant as our motors are internally balanced & if something goes wrong hey I can always throw the oem back on & wait for a fix.. As an old gear head said to me If you take the chance to buy it take the chance to experience it yourself before having wasted what could have been.

But thank you for your input/Concern.

Your Welcome!....That why there are Car Forums.....People post their experiences and thoughts...

You are right...the iM Motor is a different beast vs. a regular VVT-i toyota motor.....So maybe the Pulley will do some good....

For sure, the 86 stock on a base map tune can gain 20hp so I wouldn't doubt those numbers at all. Honestly even going with just an axle back, it could improve the response, but remember, you're shedding a lot of weight too so it helps in other ways too

No worries. I ordered one almost a month ago and they said the pulley was out of stock. When I get it installed I will post an update since nobody else has.
