Is It Worth Tuning Non-modded N/a Cars?

After changing (years ago) from a slightly modded GTST, standard ECU, to an un-tuned Power FC....

I obvisouly noticed a better midrange in power and better drivabilty overall.....even before tuned...and even better after!

My question is this,

If i have a, lets say, a 2000yr, 1.8 Corolla, is it worth adding a piggy back to punch in some extra timing and getting that better feal?

Would it work?

Are NA standard cars already at their optimum or are they running super safe where you could squeeze some extra omph outta them?

What are your thoughts?

NA cars won't lean out as easily as a turbo car, so they don't have to be as careful with the tune I guess. There are always things you can do with an NA though, like advancing the timing for instance.

All OEM cars are tuned conservatively. You can always find a little extra by tuning the ECU, especially if you're willing to always run it on a higher octane fuel. Then there's removing inherent restrictions like the intake and exhaust if you're willing to put up with a bit more noise.

As for whether its "worth" it, its up to you. You'll still need to spend money on it, and you won't see the gains you would on an FI car. If you have to have more punch and you can afford it, then do it. But I get the feeling you've got better things to spend your money on than getting a handful of fwkW on a $600 outlay with an A'PEXi S-AFC.

I had a very clean EF falcon.It was one of my most enjoyable cars.

Full exhuast

Headers

XR ECU and fuel reg

Cam

Valve springs

Lowered springs

KYB shocks

Nice wheels

I wish i never sold it. :P

Not the fastest thing in the world,but it sounded horn and was a great drive.I only mod inline 6s though.4s dont do it for me.

Its definitely worth it You will see roughly 14+kw gain from intake + exhaust

Sky is the limit. plenty of go fast bits for them! more than enough market and experience out there

twincam.net will be the best place to ask around :P

I love the power delivery and throttle response from my z...

but nothing compares to the rush when the skyline's on boost :P .

Most n/a 4 banger posers add a cannon and leave it at that.

I would do;

2.5" exhaust

good size extractors (not too large)

hi flow panel filter

adjustable cams

decent Air/Fuel management

in the end its going to be a 1.8 corolla, put a better flowing exhaust on it, filter, spend some money on suspension parts and put some nice work rims on it....

no point in modding the engine with a computer etc to get 5extra fwkw

i had an r33 gts-4 non-turbo with the rb25de engine

it had pod, zorst and unichip ecu which made a ridiculously pathetic 78awkw!

a full 2kw gain for 900bux

Thanks for all your replies.

I guess i was hoping for some sort of easy piggy back ECU that could easily be tuned from the passenger seat....leaving AFR's and punching in an extra 5' of timing or something for $500??

I'm more interested in an increase in low-midrange torque feal, upgrades.

Not interested in top output power ( i guess i shoulda stated that earlier)

Thinking i'll just leave it as is.

Cheers big ears.

Birnie :P

It's like giving a fat boy a pair of Nikes and asking him to run quickly... won't happen. So why bother?

worth tuning an NA car? it's not even worth driving one.... :D

ok ok.. some of us haven't earned our boost wings yet. I'm glad my first car was a charade i probably would have killed myself in anything quicker :D

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
