Getting The Best Out Of Your N/a Rb25de

[heapsgood]

Hey, i am soon to be the proud owner of a 1994 R33 GTS RB25DE,

Just wondering, performance and handling wise, what can i, and others, do to get the best out of the car.

Thanks.

exhaust, suspension, ecu. pretty much sums it up for an NA. you'll only get limited performance gains without spending big bucks or going turbo

Keep it above 3600rpm when driving it spirited

ok im gona break it down nice and simple for ya.

DO NOT WASTE MONEY SAVE FOR TURBO / WAIT TILL OFF Ps

but i know its hard to do so when young / on Ps (personal experience)

1. Exhaust 2.5" catback + extractors if you want them..

2. Pod filter / heat shield

3. Cut hole / feed a cold air intake

4. Get a nice body kit if you want.

5. Wait till your off Ps

Mines pulling 123rwkw with just a cat back / pod. Helps to have a healthy engine. Also manual.

Thanks, also would it be worth twin turbocharging this engine later on down the track?

nah be better to just single turbo it, use all the gts-t gear from a wreck. theres a thread for it.

get a good set of lightweight rims + good tyres (dont waste money on shitty tyres) go get good ones!!

get a set of coilovers + whiteline sway bars etc etc

simple 2.5" catback exhaust with a nice muffler (dont go cheap on teh muffler) + extractors if u really want but if ur going to turbo it dont as turbo's dont use extractors...

then jus get the basics, tinting, some nice speakers maybe and jus save save save for a turbo car/turbo your own car

thanks, the car that i;m looking at has a 3'' exhaust, which i think is too big for a 2,5l n.a motor. will that be affecting the performance?

cos some people say it does, some say it doesnt.

The best thing you can do to your non turbo engie being a P plater is go out and get some essentials (carby cleaner-throttle body cleaner, lube spray, electrical connector and wire cleaner, WD40, Wire dryer ETC ETC ETC)

Buy some automotive tools if you dont have some etc etc

-Change air filter

-Change oil filter

-Change fuel filter

-Change engine oil with an oil flush (try changing to a full synthetic such as nulon which is about $150 less than a redline oil usually $50 at automotive stores)

-Change gearbox oil

-Change diff oil

-Change brake oil

-Change Clutch oil

-Change coolant with a system flush before

-Total fuel system cleaner is 28 times more concentrated than a injector cleaner so spend your money there and it will do the best job on the place you cant reach without pulling an engine apart

-Clean throttle body (spray the hell out of it with carby cleaner and wipe down)

-Clean the AAC (IACV) (spray the hell out of it with carby cleaner and wipe down)

-Clean the Cold start valve

-Change sparkplugs

-Go around and pull all your electrical plugs out, from headlights and brake lights - throttle position sensor and O2 sensor. Clean all conections with an electrical contact cleaner and wire cleaner on the wires in the engine bay such as earth wires (will be very time consuming )

-Clean all sensors E.G. your radiator sensors may be gooped up if oil has ever come into contact with the coolant, O2 sensor can become conjested with carbon so carby cleaner can get rid of that

-Change all your relays and fuses that are not working (using a test light you will see if there is a current passing through or not)

-Test all your sensors with a multimeter providing you know what volts, resistance etc you are looking for. This will determine if any sensors are dead or not up to scratch (Read next line for other option)

-You can also have Nissan diagnostics scan tool pluged into your car (or even buy the CD and plug online) too read out any errors that may be present and you can also have your timing set, air/fuel ratio mixtures adjusted and a few more things (this is best as it will read all sensors too and give accurate readings). This test is really the last thing you will have too do as it will read your whole car and you will be able too tell things like the volts in your battery or even shut down the spark too a cylinder. When it reads 'error code: 58' you dont have any errors in your car and its running fine.

Once all that is done if you are getting the ECU scaned the tool can reset it. Once reset take it out for a nice calm drive and it will load all information from the car back up onto itself. The car will feel new and will definatly give you some power back, hopefuly get you all the way too stock power output

All up you could spend $500 here depending on what tools, etc etc, inc the Nissan diagnostics scan tool which is about $250 or you can get it done at a performance shop.

Oils and filters and spark plugs are common things and you wont pay more than $400-500 if you buy all you aerosols and oils from nulon.

And asuming you do all the cleaning and (all this is very easy and a w/e can be the best time to complete all this) taking apart of small electricals and parts you will be doing labour youself. I can see it cost all up $500-$1000

THIS IS THE BEST THING YOU CAN DO TOO YOUR NA!!!!!!!!!! so much easier than a turbo and you will gain power and also piece of mind that your car it a lot more reliable......

^^^^^^^^^^^^^^^^^^^^^^^^^^ Thats the best you can do but after that i suggest

Coilovers (height and camber adjustable)

Links (adjustable re enforced Nismo ones)

EBC brake pads and rotors (They do non turbo skylines )

Whiteline sway bars and links

Change everysingle bush on the car too Superpro nolythane bushings

Kakimoto 2.5" catback then have a exhaust shop custom make a cat and front pipe too bolt onto DKNE extractors

Falken 452 tyres or Toyo Proxies T1r (best road going tyre with very soft compound for light track work)

Thats like a little $10,000-$20,000 worth of stuff there depending on what brand you use

Hope thats enough too keep you busy

Simply just too big for a stock engine doing everday driving
