SuperSupraNA Posted July 6, 2007 Share Posted July 6, 2007 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 Link to comment Share on other sites More sharing options...
couv3z Posted July 6, 2007 Share Posted July 6, 2007 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 Link to comment Share on other sites More sharing options...

Digsy Posted July 6, 2007 Share Posted July 6, 2007 well pound for pound you may as will use a wet nos kit other than that you can De-cat 4-2-1 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 Are you talking about the same engine here?

JustGav Posted July 6, 2007 Share Posted July 6, 2007 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. Link to comment Share on other sites More sharing options...
JustGav Posted July 6, 2007 Share Posted July 6, 2007 In summary, it is cheaper to get a TT lump *grin*, unless you want to do it as some sort of experiment. Link to comment Share on other sites More sharing options...

tooquicktostop Posted July 6, 2007 Share Posted July 6, 2007 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 !

Possible detonation and possibly turning the engine into an interference design. 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 Link to comment Share on other sites More sharing options...
naybad Posted July 6, 2007 Share Posted July 6, 2007 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 Link to comment Share on other sites More sharing options...
Guest Phillw454 Posted July 6, 2007 Share Posted July 6, 2007 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 Link to comment Share on other sites More sharing options...
Gazboy Posted July 6, 2007 Share Posted July 6, 2007 How does a lightweight crank pulley create 10bhp? Link to comment Share on other sites More sharing options...
JohnA Posted July 6, 2007 Share Posted July 6, 2007 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.
