turbo the 4g63(for dummies)

[HondaHunter2002]

in order to turbo my n/t 4g63 it says that i need these parts:
Turbo ECU or SAFC (to better control the fuel curve)
Turbo intake cam
Stronger Clutch
Exhuast manifold
Turbo
O2 Housing
Downpipe
Side Mount Intercooler, BOV, And all Piping
Knock sensor
MAS from a turbo 1g or a converted 2g MAS
Fuel Pressure Regulator (aftermarket)
450cc or larger fuel injectors and fuel pump
Boost Gauge, EFT Gauge, Air to Fuel Ratio Gauge
Stronger Pistons and rings (either forged(9.0:1) or 2g(8.5:1) or EVO(8.7:1))
MLS Metal head gasket

i was just wondering if someone had the time if they could just name the part and give a brief description of what each part does and why it has to be changed/added and or upgraded.. i figured that if i understood more of what the parts are and do i would understand more about the conversion and be able to approach the project easier.. thanks for ne help ne one will give.

Turbo ECU or SAFC (to better control the fuel curve) - ECU and FULL wire harness so all electical parts work (MAS, selnoids... sensors) SAFC is an air to fuel controller. It controls the amount of fuel so you don't run too much or too little gas. It's manually changed.

Turbo intake cam - need more airflow for better results. (not necessarily needed but loss of HP if not.)
Stronger Clutch - stock clutch will slip with over 2000lbs of pressure

Exhuast manifold - to fit the turbo

Turbo - for that added 75HP
O2 Housing - the housing which is used to bypass the exhaust past the turbo turbine through the wastegate.

Downpipe- so it fits the turbo exhaust manifold

Side Mount Intercooler, BOV, And all Piping - turbos consense and heat up the air, SMIC cools it down for added HP and so you don't blow a #@%#@%#@%#@%ing piston

Knock sensor - when predetonation occurs in turbo cars, the sensor picks it up, tells the ECU and it lays off on the injectors

MAS from a turbo 1g or a converted 2g MAS - the Mass airflow sensor is too small in N/T

Fuel Pressure Regulator (aftermarket) - too small to return the gas

450cc or larger fuel injectors and fuel pump - need more fuel, period.

Boost Gauge, EFT Gauge, Air to Fuel Ratio Gauge - boost guage to make sure you are running good boost, EFT -exhaust temp guage i believe, AFR guage - make sure you aren't running lean or too much gas

Stronger Pistons and rings (either forged(9.0:1) or 2g(8.5:1) or EVO(8.7:1)) - n/t pistons will blow

MLS Metal head gasket - raises the head and also is able to withstand the psi in the pistons without leaks

Hey, you don't need so much crap. Here's a list of parts you DON'T need to buy:

- Pistons: You don't need forged pistons unless you will be running over 18 pounds of boost, which you probably wouldn't anyways since NT cars have higher compression and are more prone to detonation. (9.0:1 vs 8.5:1)

You can run cast pistons to about 350 horsepower without a problem. What destroys the pistons is detonation, not horsepower, and many people don't seem to understand that.

- SAFC: just good if you are running outrageous boost or if you have a hacked 2G MAF.

- Clutch: The stock clutch will last you as long as you don't do 4000RPM clutch drops and burnouts. However, if you are one of the guys who beats up clutches, then instead of a new clutch, start saving for a new transmission, cause DSM trannies are some of the worst crap ever made by man, and you'll surelly tear it apart once you abuse it with the turbo. (turbo and non-turbo trannies are the same strenght)

- Fuel pump: Just rewire the stock fuel pump and you have more than enough fuel up to 350HP

-Turbo intake cam: Not needed unless you really want to squeeze every little bit of HP from the car. You'll probably get more power from porting the heads or from a good intercooler than from a cam specially with low boost.

-Aftermarket Fuel pressure Regulator: If the turbo cars run with a stock regulator, why can't you?

- Metal head gasket: You wont be running 20 psi, so the metal gasket is just a waste of money.

I can get you the turbo, manifold, intercooler and piping for about $500 with shipping included, let me know if you are interested.

If you think I'm talking B.S., go check this website:

http://www.hahnracecraft.com/auto/eclipse/eclipse.htm

They sell turbo kits for the 2G eclipse and make 390HP on stock pistons with race gas and 320 with 93 octane with the stage II kits. Don't underestimate the strenght of your little non-turbo car

sounds very interesting.. shoot me an email at [email protected]

You don't need pistons guys, run a 2mm Steel head gasket and that should lower your compression so you can run more boost. And by the way, the crank on the 2.0 DOHC turbo and the 2.0 DOHC NT, are almost the same,d ont' let people fool you, I have both in my garage and they are basically the same damn thing, just one is 6 bolt, and one is 7 bolt.

No one said anyting about a crank?

hey guys i was wondering i bought a 91 gs and recently purchased a 91 gst engine for it and i need some help with the wiring and all that i heard that you can run 3 wires form the orignal harness without buying a new one. but i got no clue what to do so if you know anything about this make a new thread.

just get turbo wiring harness.. much easier and it's not that expensive
