Exhaust
Intake
Pistons
Cams
Cam gears
Pulley's
Chips
Rods
Intake Manifolds
throttle body
Radiator
Fuel pump

............and anything and i mean anything else i can do to my car please tell me because im doing every upgraded part possible or nething that will give me more horsepower or torque...thanks hope i get a good response need to know as much as possible

You are no understanding the concept behind modding your car.

By the way, you are missing the turbo.

 

[talon3787]

umm....to bad i no almost everything about my car and im just tryin to know as much as possible. plus i do understand b/c i work on cars all the time and i dont want turbo..im going all engine
but thanks for your wrong comments

 

[TimG]

So you know ALL about cars, then why ask the DSMers? You want info. Here you go...
Exhaust - headers all the way to muffler. As straight through as possible. 2.25" would be sufficient. Screw the cat, screw the resinators. Live with loud.
Intake - solid pipe intake. I suggest you look at my old sticky post on the top on the non-turbo page intitles 'overkill on the CAI'
Pistons - highest compression you can get with a large bore. Maybe .03" over. Try 12:1 pistons for max power output.
Cams - High lift cams in this situation are necessary. You want to create a vacuum in your engine to suck as much air in as possible.
Cam gears - SEE CAMS and time these gears so that vaccum has it's max pull.
Pulley's - yeah yeah, lightens rotational mass. Not a big HP increase. You will most likely be lacking the harmonic balancer and may damage your engine. I'd look for ones with a harmoninc balance.
Chips - No one makes one. In in your case 'chip(s)', two.
Rods - Stock 91 rods are PLENTY.
Intake Manifolds - Port it out if you want. Won't help too much in a sub-230HP car.
throttle body - n/t t-body is huge. leave it.
Radiator - stock one will suffice. Go fluidyne if you see overheating problems.
Fuel pump - stock turbo fuel pump will give you enough fuel.
Injectors - keep stock until you hit fuel cut. you probably won't.
Flywheel - lighten that bi*** up as much as possible and step it for your new clutch. You must get a new clutch cause the n/t one sucks.

There you go pal.

Exhaust - home made, doesn't get any cheaper than that. maybe a well ported pacesetter header and a n1 style muffler for max flow. no bigger than 2.25 to 2.5 inches though.

Intake- again make your own out of a 2 1/2 with a reducer at the mass air sensor or 3" with a reducer at the tb. might be a little off as i can't remember off hand how big the exit is at the 1g nt maf offhand.

Pistons- arias makes good ones, but honestly it doesn't really matter if you're staying all motor

Cams- hks makes the best street cams for our cars

Cam gears- may as well stick with hks again here, very well built.

Pulley's- unorthodox racing i suppose

Chips- apexi s-afc 10x better than any "chip" but if its a chip you want contact jet and shell out $400 instead of $300 for a s-afc.

Rods - ok here you have a weak 7 bolt engine, but those rods will still handle 400hp and since they're smaller than the 6 bolts they're a little lighter and that's a nice little bonus.

Intake Manifolds- venom makes a cheap one, but prepare to lose low end torque

throttle body- maybe bore out the nt throttle body, but its already huge, just have it powdercoated or polished to make it pretty i suppose.

Radiator- go with a fluidyne and spal flat fans if you feel you have to but my nt radiator has no problem running a turbo engine at full boost on hot summer days even with the water cooled oil cooler and water cooled turbo.

Fuel pump- stock turbo pump will give you more than you need.

Injectors- if you have an nt you can throw in some low impedance injectors from a 1g automatic really cheap. 390cc will be more than enough, but you'll have to pick up the injector resistor pack for them as well.

Flywheel- to my knowledge noone makes a lightened flywheel for the nt 1g's. just drop yours off to a machine shop and tell them what you want.


there hope that helped you.

Thanks like the input so far keep it coming and tell me if theres anything else that i didnt mention that i can do to make my car faster. thanks

How about some heads with a nicd port job on them. I would think that would be nice.

I plan on doing these things above and looking into a wet NX kit or Zex kit and then also possible a turbo with a nice big intercooler and the gizmos to go with it.

the cylinder heads on a 2.0 nt are identical to a turbo car so they'll flow plenty good for 200+hp. a good set of hks cams like the 264 would make a great addition to the stock head. so you could look into maybe some stiffer springs and retainers and a rev limit removal and wind the thing out to 8-9 grand i suppose. that would help.

 

[MorpheusGPR]

Mavisky,

Please tell me more about the heads and the HKS cams and what I can do wiht the revs. Would I need to rev that high, i.e. will it sill hold together and make power that high? That might be an added bonus for using a wet nitrous kit to get more out of it.

Please let me know what you think.

Is that 264 cam going to be the best ones for me?

I need two of those then right? (yeah import nub)

I was thinking about some built heads and the nthose cams and a wet kit at 75hp from NX with the goods.

How do I tune it then for those higher revs and what ever else I would need.

Can you recomend some ignition upgrades other then wires and colder NGK plugs (well which ones and what gap would be nice?) but like a high spark coil, ignition box (MSD?) etc.

Thanks a lot.

You are near where I am from, I am from Churubusco, relocated to Greenwood south of Indy but will be going home to track down my escaped boa in my parents place

with all the standard mods a higher rev limit will allow you to continue to utilize each gear and its resultant torque multiplication to your advantage. essentially you could hold on to first gear to almost 40mph if you were reving to 9000rpm. for a street car the 264's would be the most practical although the most power might come from the 272's. since i don't know of anyone doing back to back comparisons of the cams on a dyno on an nt i can't honestly say which is better. remember biger isn't always necesarily better.

in your car i wouldn't go with colder plugs for your ignition, that's a mod for the turbo guys. for you i'd get a nice set of bosch platinum +4's (had em in my nt, and the a lifetime guarantee is always nice) or if you money really isn't an object get some iridiums. then maybe pick up a set of spark plug wires (who's the best is arguable, but accel makes a good set for only $47 and they're readily available at any performance or auto parts store that sells accel stuff). then for the ultimate in ignition for your setup i'd go with a msd dis igntion setup. i think its the dis 6, if i remember right this would give you an adjustable rev limiter as well a separate revlimiter when the clutch is depressed for launch control (i think). your stock coils are really pretty good, they've driven many a dsm into the low 11's and 10's.

without replacing pistons the next best step is probably the nitrous setup. i'd start at a 50 shot and see how the car handles that, then adjust the jetting for 75 if all is good. might want to pick up a stock tsi fuel pump to make sure you have adequate fuel.

 

[MorpheusGPR]

You would go platnium plugs even with the nitrous setup? I thought that was a no no?

Which heads would you suggest so that a 9k RPM redline could be achieved. But also I want them to be some of the best heads I can get.

The HKS cams with the 264 sounds like what I need but how would the 272 do with nitrous and being driven?

The underdrive pulleys I was thinking of have..crank, water, and alt. in a set for about 320 bucks I think.

That MSD is what I was thinking as well, letting me change the redline will be nice. You think its good to 9k rpm with this setup? That sure would be different for me, my Lightning only goes to like 5500, .

Sounds like you got me a good start here. I am also looking into light weight wheels, maybe a change in gauges (although if I go to a 9k rpm redline I will be looking for some with a so stated tach) and some sway bars and strut bars for handleing.

 

[MorpheusGPR]

Oh one other thing,

Exhaust. I know the catback is going to have to be custom bent I guess, and I would like to at least get my stock manifolds ported nice (slow boy I think is going to get to do that) but what about mufflers and cats. and I saw something about porting the O2 housing?


As for the 9k rpm redline, will this kill my engine? I know imports are high revvers but that is nearing double to what I am use to.

. You don't have an O2 sensor housing. That's for turbo cars only. Your O2 sensor is built into the exhaust manifold. You want the best exhaust? Port the hell out of your stock exhaust manifold with a carbide bit. Do this on the ports and the bottom side. Then get 2.5" piping custom mendrel bent with a high flow cat (if your state deems you to need one) and some sort of a stock looking aftermarket muffler. You could get a race fat can muffler but that's not my preference even though I have one on my car.

Just take it to a custom exhaust shop and tell them what you want done.

i'm not a nitrous expert, look into the nitrous vs platinum debate elsewhere on the site.

like i said before for max power and the upped redline the best head for you would be a totally stock head with new cams, springs, and retainers. if you want the best compromise between power and driveability go with the 264's, if you want max power the 272's might be better. although like i mentioned before the 272's might actually be too big for your current setup so they might not be any better or could potentially be worse.

beware of under drive pulleys that don't have a harmonic dampener built into the crankshaft pulley. they could cause potentially serious damage if your cars rotating assembly hasn't been perfectly balanced.

while the engine will spin to 9000 rpm, as usual a set of new crank and rod bearings along with the balance shaft elimination mod would be a good idea. many of the top dsm racecars will run the 4g63 up to around 9000 rpm.

about the exhaust, either do as timg mentioned or get a good header ( i can't remember who makes the other one aside from pacesetter) and then get a matching 2.5" mandrel bent catback exhaust from any of the better dsm vendors for a 1g fwd. both the fwd turbo and the fwd nt use the same exhaust layout.

also keep in mind that if you're going to be winding out the engine to above its current redline of 7000 that the manual trannys in our car can be a bit bitchy at that high an rpm. before long you may want to look into a good rebuild. it'd be nice to get some of the upgrades available like steel shift forks, and double synchros, but our nt transmissions are different and don't fit any of those parts. the best we can do would be a stock like rebuild.

as for handling, strut tower braces and sway bars should come after a good set of adjustable shocks and a spring setup. whether you go with coilovers and adjustable shocks, or some eibach or equivalent replacement springs and adjustable shocks is pretty much up to your personal preference and the depth of your bank account. if you were to buy and do all the work i've mentioned in here yourself the parts alone would run you a couple of thousand dollars easily. if you need help doing it you can easily double that number.
