Need help tuning n/a

[MySupra]

need help in tuning my 1994 manual NA

i dnt want to turbo it just yet

any ideas in what else can be done???

[stevie_b]

Not a lot. Decat, that's about it.

[Kirk]

Not much besides decats or a manifold and cat back exhaust.

 

Best thing to do it totaly service the engine and ignition components but dont think you can net 40bhp off an exhaust cause it just doesnt happen

[MySupra]

cheers

[Marco79]

Only options are to replace the stock panel air filter with a k&n or equivalent, a stainless tubular manifold and 1st decat other than that mate your paying hundreds for the odd bit of bhp failing all of that for the track days and the odd bit of fun nitrous works a treat

[Kirk]

Why would you replace the stock panel filter when its probly much more efficient than any induction kit?

[Tricky-Ricky]

Other than whats been mentioned, just

save your money for a turbo conversion, much better spent.

Just the filter element NOT the box system as that is defo the best system for the na

[Kirk]

Meh i disagree as there will be no noticable difference made by replacing the filter to another one that flows a little more.

Fair enough but if your wanting to tune an engine every little bit of extra air flow helps, it was just a suggestion as it is one of the few mods that can be made to an na without costing a fortune

[dr_jekyll]

tune the chassis if you want to make it sharper, suspension, good brakes , shed weight. decent tyres, light whells . without a turbo , trhe engines not going to gain alot

Defo agree with that

[Max Headroom]

Change all the fluids, won't make the car go faster but will improve the driving experience.

As others have said, there's not a great deal of options if you don't want to include Turbos. Best advice is service it, make it sound nice and handle and stop better

There is quiet a bit david2009 has done ..check out his profile quiet impressive

Might be worth asking him just how much time and money he has spent as well;)

i bet he's spent far more time working on it than driving it, and we are all waiting with anticipation for the final dyno plot.

Best to enjoy the car for what it is, save the money and do one of the following:

 

1) TT conversion (Keron)

2) NA-T (Kit from Whifbitz)

3) Sell up and buy a TT

[st1989]

yeah best thing to improve the engine would be to reduce the restriction in the airbox system, and also exhaust, as said above giving the engine a good check over will help it run a lot smoother!

 

could go for a new exhaust system with decat and no silencers to reduce the restriciton in the system and get the manifold and downpipe heat wrapped or coated, reduce the temprature around the engine?

could go for some weight loss in the car?

cams?

 

 

really depends on how far your willing to go without the addition of turbos.

Full service - all fluids, oil filter, air filter, plugs, distributor cap, rotor arm, plug leads, oxygen sensors, etc.

 

Tuning - tubular exhaust manifold, 2nd decat pipe, cat back exhaust designed for a 2JZ-GE. That's about it, don't expect huge gains, I'd guess around 15hp, but the car will feel more lively.

 

I'd spend the money optimising the handling and braking, get the suspension arms/joints/bushes checked for wear replace with OEM Toyota parts. Good set of shocks and springs, good quality tyres and a full geometry/alignment check.

 

Braking - If you have the smaller Supra brakes fitted, replacing with the larger Supra brakes will make a big difference. If you keep the smaller brakes then a quality set of pads, braided stainless steel brake lines and decent brake fluid will get best out of them.

[Tricky-Ricky]

Getting more air in and out of an N/A engine is just half the story, optimizing the fueling and timing for the improvements, is as, if not more important to the whole picture.

[TonytotheB]

I asked the same question - then bought a TT lol

[w41k3r]

would upping the compression not be an option too ? i`d say just go for power to weight make it lighter

[Monkpower]

Alright mate, i'm in the same boat. Got a 95 NA. Got a few plans for her.

I've got an HKS super power flow induction kit which I will make a heat shield for. 2nd sports cat going into a single box system will be next. Coilovers and bushed should stiffen things up on the bendy stuff.

I'm happy with my NA so if you are too don't listen to everyone who says 'get a TT, get a TT!!'

Obviously he isn't if he's after more power!

 

A lot of people seem to be getting their noses put out of joint lately by other club member suggesting that the ditch the n/a, and buy a TT; it's not a dig - just a sensible answer to the question "how can I get more power from my n/a?". I'm sure a lot of people have gone down the n/a tuning route, spent 1000's, then come to the conclusion that buying a TT would have been a cheaper and easier way.

 

I myself had a n/a about 3 years ago; I asked the question and got exactly the same reply - buy a TT. I took the advice. If its just the Supra looks and straight 6 roar you're after, then the n/a is fine - if you want some performance then you need to look at swapping out the engine, or buying a TT. Simples

If your going to keep your na then spend money on it, exhaust, manifold, full geo, ignition parts, full service etc

If your plan is to go tt and the na is a stepping stone dont waste cash chasing hp on the na and put it towards a nice tt and bpu parts
