N/A tunning for newbie!

hi folks, just bought a 3.0ltr n/a and it's lacking a little in power, whats the best thing i can do to see some progress?

Any advice will be great, cheers

Andy

it been talked about loads.

try using the search button, you will loads and loads of info.

enjoy...

Ahhhhhhhhhh! Search, thats what it for.

not much you can do mate, NA guys just sort out the exhaust from the engine back.

You can buy an NA manifold, and a 2.5" exhaust will do.

not much else you can do to improve power in terms of value for money, plenty info on it already though mate, search

well

pound for pound you may as will use a wet nos kit

other than that you can

De-cat

6-3-1 manifold

Inlet cam

Light weight crank pulley

Exhaust cam (would require the dissy to be remove and control by a ECU)

ECU

port and polish

skim the head

Put your car on a diet

and finally your can put a turbo on

a little underpowered?? 225bhp. hmmm depends non what you have been used to. should have bought a twin tubbie. theres loads for sale quite cheap too

Are you talking about the same engine here?

traded a 300zx tt for the "sensible" 3.0 n/a supra, missing the twin turbo but loving the look of the Toyota!

Dump the tt engine in! lol Thats what im thinking of doing!

am i just being stupid or if you put 4-2-1 manifold on wouldnt you be missing 2 cylinders

Just go slow and look cool......

H.

One does wonder actually...

Light weight dampner as well (ohh dear...)

amusing

Want more power, buy a freakin' TT. Want a good daily driver, buy a freakin' NA

Inlet cam

Light weight crank pulley

Exhaust cam (would require the dissy to be remove and control by a ECU)

port and polish

skim the head

The above items worry me the most...

1. Light weight crank pulley -> Are you are aware of the potential damage to the crank and gearbox by fitting one of these. What benefits would expect from this.

2. Exhaust cam -> Fair play with the cam, but are you aware of the amount of work converting the car to Cam/crank sensor ignition? Doable at a price.

3. Port and polish -> Again, what sort of polish? swirl polish or mirror finish on the intake?

4. skim the head -> Why? To gain some compression? do it properly and change pistons, thinning the squish area by using a thinner headgasket or skimming the head will result in a lot of nasties. Possible detonation and possibly turning the engine into an interference design.

In summary, it is cheaper to get a TT lump *grin*, unless you want to do it as some sort of experiment.

Amen!!

jezzybabes 3k you will have a tt:D

Why waste your money, put an exhaust on, maybe a manifold and enjoy it, save your cash and get a TT later as your NA will be worth very little more than it is now even if you spend a fortune on it

Blimey I am a miserable git at the moment !

See shane's post and supercharge it:)

humm

1. from the reading i have be doing a light weight crank pully can provide a 10bhp and there reasonlby cheap from america, but seems to be a good addition with the cams.

2: no idea of the work included i'll be paying someone else to do the work

3: be honest not looked into that much, but i will be shortly

4: not researched it yet but sounds a no no already lol

Best thing to do is up rate brakes, suspension, anti roll bars ect ect then just get a direct port nos sys for the straight bits

Lol i wonder how many of these threads there is now.

Its like the NA's path, sign up, say hi, go to supra section, ask for more power:d

How does a lightweight crank pulley create 10bhp?

How does a lightweight crank pulley create 10bhp?

It doesn't.

If it took 10bhp to spin the pulley, can you imagine the rest of the ancilliaries?

You'd need 200bhp just to overcome the extra mechanical friction.

These pulleys often tend to be underdrive too, so the lower current from the alternator helps your ECU work better and the fuel pump shoves more under stress. Or maybe not.
