N/A Tuning

[Pavin]

First I will start with a disclaimer, the Corolla is a slow car and no matter what I do it will be a slow car. I understand this, I have my dad's C350 to drive if I want to go crazy fast. So if you dont wish to add productively to the thread please just leave

With that aside, lets get this thread started. I wish to add a bit of power to my Corolla with out spending 5-6K on a turbo/supercharger. So basically I'm open to hear any ideas/info on N/A tuning etc.

(Auto S)
So far I have
Takeda SRI & OBX Muffler.

What I'm considering
Headers(carb legal c'mon PPE!), NST pulleys.

After this I have just about no idea on port, polish, spark plugs, etc. how these things improve HP/TQ or anything.

(Also I'm keeping suspension questions out of this thread to keep it on track)

Thanks for the read

Headers, Intake, Exhaust. For sparkplugs im sure we have one of the best ones since they're iridium. Get a pivot throttle controller for way better response. Nst pulley. Unichip to tune your car. Thats probably about the best your going to do without forced induction....

Standard "breathing" crap..

Just about what I had in mind, what about the port & polish route, I've seen it done on previous corollas? Regarding spark plugs I thought similar plus new car so compression should be tits.

Regarding the Pivot Controller, from what I've read its basically a signal amplifier and I could receive the same effects by pressing the pedal more...

I've also heard strange things about Unichip, that it could actually cause problems, and aside from air/fuel this wont do much will it?

Thanks, I want this thread to help others in search for a bit more pep, rather than having to search and post questions with others just telling them its stupid.

A nice N/A tuning will often cost more than force induction. And the 1.8L on the 10th gen is no even close to a performance engine compare to the 2ZZGE 1.8L. And since the 1.8L on our car is fairly new, there aren't any performance fast cam that we can buy in the market or other engine internals performance add on....so rather than the usual stuff, it is hard to make it go fast without spend $ for a full n/a build or force induction.

Until you install one you will never understand the benefit. I tried pushing the throttle more, it doesn't get rid of the delay. This single mod will do more to your driving fun than even the intake & exhaust. Those sound nice & I love mine too but the Pivot is simply an amazing product & must be fely to understand the benefit.

To bad you have an auto because my 5M feels very quick & responsive now with the Pivot, intake & exhaust mods.

On your first point, I'm curious to what an N/A tuning consists of? And what to look out for?

Second point, I dont understand what you mean by performance fast cam, also could you go into more detail regarding engine internals and how they'd increase power etc?

I'm seriously considering the Weapon R alternative as it seems the pivots are all but run out!

Hopefully one day by sheer luck I'll come across a wrecked Tenth Gen with all manual transmission in perfect condition and be the first ever to do a swap

On the plus side, Flawed (Greg) has an auto & it made a huge difference when he installed the Pivot on his LE. I'm sure that the Weapon R will work just as well.

As thestone11 said before its not a performance oriented engine it would take custom ground cams(since none are made for this engine) upgraded valvetrain before you see any real power and even then you will really need a piggy back computer to make every thing work like it should.

So basically its the waiting game for the performance parts to start rolling out for the tenth gen :/ Hopefully it ends up coming out..

Yes I understand its not a performance oriented engine but just trying to get as much power I can from this 1.8, and not be neck in neck w/ a prius

i have an auto and the weapon r throttle controller definitely makes the car feel different.

flooring the car completely reduces that 2sec delay where the corolla is "asleep"
and in mid range rpms the delay practically disappears. it feels way different and im glad i did this first cause although its not a true increase in hp ...it definitely feels more than an intake and exhaust.


just spend the money and do a 2jz swap,. there....fast car....done! yay!

Since the 1.8L on our car is not aim for performance, so I don't think we will see any of those high performance engine internals, such as fast cam, forged pistons, intake manifold....etc. And as I mentioned before, building a fast n/a engine will cost way more than a force induction setup, porting and polishing of an engine block costs extensive labour cost and experiences to do it right. So for that it make no sense to do a full n/a build unless you will be racing the car under a race class that specific engine displacement and wouldn't allow force induction. Even so, I don't think anybody will use the 10th gen 1.8L when the 2zzge and the more powerful Honda B18 or K20 series are very easy to locate.

Before doing anything serious to your engine, I think you should learn more about engine first. You should do a little study with the differences that n/a engine and force induction engines, see how they achieve their power from.

If you are not ready for that, I suggest you to stick with the normal routine, like intake, headers, exhaust, throttle controller......etc. And if you really demand a faster car, just go get a faster car, don't expect too much from the rolla in terms of performance. For about 6k, you can easily find an used SRT-4 neon, older Honda SIR that will provide you with a little performance oriented platform.

Nothing to worry about as the Prius isn't faster than the Corolla, I have a new 2010 Prius to testify to that fact. Although the 50+ mpg the Prius delivers is awesome.

stone11 just said what i was about to say as well.

I do understand that you said it would be more expensive to do a n/a build(labour aside I have a mechanic who got laid off from the place he worked at and does work super cheap).
I think your missing the point of this thread, if I havent made this clear already, I have a fast car at my disposal, If I want I can borrow my parents C350 V6, or the ML500 V8, thats not the issue! I want to get as much power as I can from my corolla. Instead of the usual "not a fast car, dont try it, just supercharge" that most seem to push I wanted to get other ideas other alternative I or any of TN members might be interested in taking to increase the power of our cars!

The normal I/H/E route makes a very small difference to Rolla's as I'm sure most of those who frequent TN know, however we still do them, Why? For more enjoyment and power from our cars. If we were to stick to this no go, or blow logic we would all be driving full stock (engine wise) cars.

Also, any engine mod I'd make would be after my warranty was up completely, giving me plenty of time to plot and wait
