What do I need to turbo my N/T?

[94_eclipse]

I have a 94 eclipse with the 4g63 engine. A friend of mine has a 1g that was totaled and it was turboed. I am new with DSM's and well imports for that matter. I am not sure what all i would need for my car to make it turboed. I know i need the turbo, intercooler and pipes. But all the other stuff im almost clueless. He said i can have anything i need so i just need a list. If anyone could help me out with a list i would be greatly thankful. Thanks!

Quoted from hypno in the 1g n/t forums

The 4G63 NT Engine, and How to make a turbo kit for it!
I am writing this post, to clear up a lot of common misconceptions about the 1g 4G63 Non- turbo motor.

There were 3 models produced:

4G63 F 6 Bolt Crank 135hp
4G63 M 7 Bolt Crank 135hp
4G63 K 7 Bolt Crank 167hp (94 Talon ES SE only 250 sold in US)

(I will now call the motors by there corresponding letters: F, M, K)

F and M had 240cc Fuel injectors.
K had 300cc Fuel injectors.

F and M had short lift period cams (less then turbo on intake, same on exhuast)
K had long lift period cams (same as turbo on intake and exhaust)

Cast Piston with compression ratio of 9.0:1.

These pistons are weaker then the turbo pistons, and also have thinner ring shelfs.

The 5spd Tranny’s on the Non-Turbo have a higher final gear then the turbos, allowing for a faster bottom end, but less top end (unless there is more horsepower put behind it).

A Faster Bottom end, means beter ¼ mile, so why switch to a turbo tranny, all the parts inside are the same strength, just not the same gear ratio.

I have a 4G63K in my car and it toped out stock at 152mph, clock by radar gun (license suspended for 6 months for that stunt, won’t do it again).

At Moroso Speed Park with 130 Octane gas, the car ran a 14.9sec ¼ @ 84mph with just a cut air can and complete exhaust system (ported and polished exhaust headers, not performance ones).

Other then the things listed above the engines are the same as the 4G63T except for the ECU and a couple of sensors (knock and MAS).

But what can be done about a NT to make it faster….. NOS would be the most logical solution for the price. But the increased pressure from the NOS can lead to the same detonation as a turbo, melting internals, (so don’t go over 25 shot, but I don’t suggest it for long periods of time).

And then you think turbo… Too expensive!!! Or maybe not!!!!!

To make a NT into a turbo pocket rocket, is really no that hard, with a lot less boost then the turbo cars.

First there are a few things you need:

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

That’s it!!!

The common misconception is that lower compression pistons are needed. But this is simply not true, the Chrysler portion of DSM in the 60’s was known as the HEMI motor Corp. I4 Hemi Head were designed just for the 4G63 motor, allowing for extreme pressure to be achieved. All that you need to do is put in a Multi layer steel head Gasket to contain the extreme pressure.

With more pressure, you need more fuel to stop detonation. As long as a turbo ECU monitors fuel or a SFAC does, the engine will be free of detonation at standard levels of boost.

By Standard levels of boost, I mean on a NT 8psi or less, and this should take a car that produces 135hp (F and M) and 167hp (K) up to about 230hp (F and M) and 250hp(K), (maybe 10hp or more less).

Ok a turbo maxing at 8psi (even a TD05 with a 16g compressor) will spool at about 1800rpm (already tested on my friends 94 gs, and worked perfectly), allowing for 13 and 12 second ¼ miles. (My friend ran a 13.23@104mph on this setup I created for the NT 1g carsat 8psi).

You must do the install right though, THIS IS NOT FOR THE NOVICE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

All the parts can be purchased used for as low as $600.00 and new for $2500.00 (Plus the price to install, if not doing yourself).

Are you turboing the non turbo engine or using a turbo short block
Either way youll need everything listed above
If your going to spend the money for this swap which Ive done before
you might as well build the bottom end, or at least install turbo pistons.
Without a tuning device or chip that 9:1 compression wont like your stock timing maps very well when boost is added.

Youll also need a turbo slave cylinder which is different
and youll need a turbo cars ecu, all the turbo components ( turbo, mani, bov, w.g. etc.)
and on top of that a turbo cars tranny and clutch and flywheel which you should get
aftermarket units while your at it.
Talk to mavisky, a wiseman on this site whose done this swap and he'll tell you that he
grenaded a few n/t trannys before just going to get a turbo versions tranny in which
the n/t tranny is indeed not as durable to high hp.
Let me know if you need more info because there is a lot more to provide.

Thanks guys! ill make sure i do that. Its gona be a few months before its done but i plan on starting it soon.

Why would he go to a site that is based on a second generation eclipse. They dont use the same engine in the 2G non turbo's. I dont see how that website would even be any help to him.

I do suggest checking the 1gnt forums as well, there is a section related to turning your g63 into a g63t.
