Anyone installed or will be doing these? Have any input? As they're on my list.

Good finds

 

[Asphalt Anarchy]

Yeah, both of these have been on my list for a few months. Probably going for the Crank Pulley first since the Headers aren't all that useful until I decide on what to do about the rest of the exhaust.

Thanks! I usually do extensive searches before putting on my list/orders/Future mods lols.

Sounds good! Let us know how it is on this post of possible so we don't clutter the forums lol.

I will most likely get the crank pulley then just replace the piping from the end of scubba muffler to the black muffler (second muffler @ U bend removal) with 2.25 piping & try to shorten that U bend to be a little straighter.
I'm thinking of slowly getting the DC header afterwards as I feel as if there may be an aftermarket that may make a longer one to replace the full header to cat to scubba muffler soon.
(I lurked on Scion TC & read aftermarket parts that replaced there header, stock cat down to the scubba mufflers they had that would also be able to join with aftermarket exhaust systems)

I really want to see what the collector on the inside looks like first. If they were anything like Borlas initial first run quality.. I think I'll wait for a bit. Those crank pullies do look really nice though !

You sure have a knack of finding aftermarket parts I'd never find in a million years of Google searches! Well done!


Not trying to be a party pooper but I have read a lot of dubious things about lightweight aftermarket pulleys. It isn't the under-driving that seems to be the issue but that the effort the manufacturer put into the OEM pulley in terms of harmonic balancing is thrown out the window with these things. The central problem is that the main reason these things are lightweight is because they do not employ a harmonic balancer to the same specs as the original manufacturer's one.


I suppose it depends who you ask, but when I read stuff like this:

Thinking about buying a lightweight front pulley? READ THIS! - D-series.org


http://www.atiracing.com/products/dampers/damper_dinan.htm

It puts me off these things completely. Please don't shoot the messenger - I am just pointing out a dissenting view towards this particular type of modification The exhaust header on the other hand looks very interesting.


I should point out there is absolutely no reason why you cannot buy the aftermarket lightweight pulleys for the aircon, alternator and water pump. The Fluidampr company also makes proper aftermarket pulleys with correct harmonic balancing but so far they only make one for the FR-S in the Scion range.

 

[davect01]

Specifically, the lightweight pulleys are only advantageous if you have a highly tuned car. Generally, on a stock engine you won't see any difference.

Now headers are very useful, but only if you include them with a proper exhaust. You have to think of the entire exhaust system.

 

[MiScion]

But wouldn't headers only really come into full use when you tune the ecu to compensate for them. At that point you would do intake and full exhaust and then tune for that to get the most out of it otherwise typically it doesn't do anything and could potentially throw you're AFRs all over the place

 

[davect01]

Yes

It should be seen as part of a system.

 

[iMQuinn]

Thanks for the input or your opinions guys.

Although imho & experiences I'm not too worried about the LW Pulley as when they say Harmonic dampers (usually in older engines) the pulley would have this hard rubber in the middle of the pulleys.

In our newer engines that are usually now internally balanced/tuned (No rubber in the middle of our pulleys for "harmonic dampening effects) is to why I'm not too worried. This issue was also brought up in the older 1zzs in other forums that reported
Minor issues. Like dimming lights or not strong enough a/c etc. But we're later fixed.. From my past understanding it frees up HP that the engine already has from being LW rather then you gaining & Usually those people who report bad things are because they beat on their vehicles & don't drive/maintain them well.
From experiences with fam/friends doing n/a mods I can say that yes it may not be alot but like every penny.. That little HP counts.

I can say the same HP wise for the DC headers & exhaust system.. Yes the exhaust is key to the header other wise you'll just gain sound & like 1-4 hp like the 1Zs from past experiences lol. Some reported porting their headers showed same/better to no results then getting a aftermarket header.

Anyway I don't want this to turn into a debate. I just wanted opinions and or if anyone has an opinion who HAS already installed them.

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.

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.

Nst Pulley Ordered (Blk) will be updating along with exhaust! DC headers soon after.

 

[ultimica06]

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

 

[Ochoa365]

So has anybody installed this yet?

 

[blueBallz]

Yea all this talk of people getting these and not a single update.

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.
