2g N/A to Turbo Conversion

[turbo2g111]

I was wondering how much work/money would be involved in turning an n/a 2g eclipse into a turbo. I don't mean slapping a turbo on the 420A, but dropping in a 4G63. I have the opportunity to buy a 96 Eclipse RS for very cheap because it has a bad engine, but I wanted to turbo it. I know that I would need a turbo ECU and a new gauge cluster. Also, I know the engine mounts are different, but could that be changed? Also, the exhaust system would have to be upgraded, and it would need the whole intercooler system put in. What else?
Thanks,
Tim

New accessories, brackets, drivetrain, engine harness...

It doesn't matter how much money you save buying the RS; you'll spend more money trying to convert the 420A to a 4G63 than it would cost to buy a GS-T or GSX in the first place.

more of a headache tha anything, and from what i hear. it is to much money

For the record, the exhaust systems (after the cat) between the RS/GS and GS-T is practically identical, save for the muffler itself.

Also, the engine mounts can be changed, but it requires significant welding skills and substantial knowledge of chassis fabrication/modification.

for laughs

Here's the parts list.


Exhaust Manifold (1g MT, 2g, EvoIII)
Turbo (14b from a 1G MT, 16g)
02 sensor housing (1g MT, 2g, EvoIII)
02 sensor from a turbo car (it has a longer wire, to reach the new sensor location, you don't need it if your wire already will reach, or if you rewire it yourself)
Turbo Fuel Pressure Regulator (1g MT, 36 psi base pressure)
450cc turbo fuel injectors
Turbo fuel pump, or upgrade pump for turbo car
Resistor pack for 450cc injectors
MT federal turbo ecu matched to the year range of your car(1990 is different from the 91-94 cars)
Wastegate actuator
Aftermarket boost gauge
new fuel injector o-rings
new exhaust gaskets
1g Turbo throttle body
Throttle body elbow (1g or 2g, 2g is better)
Metal check valve for the purge canister line (plastic ones blow out)
UIC pipes and bov
Turbo intake tube w/ bov return hose (dont vent the BOV)
Turbo MAF and pigtail for wiring harness
16ga wire (a few Different colors)
wire loom, solder, electrical tape, heat shrink
electric fuel pressure solenoid and pigtail
knock sensor and pigtail
1g sidemount intercooler
lower i/c pipe, hose, J-pipe and turbo outlet gasket
turbo aircan
Downpipe
Turbo Oil Pan
Oil drainback tube
5 feet of 3/8" coolant hose (hydraulic hose also works, dont use fuel hose)
Turbo oil feed line w/ banjo bolts
Turbo coolant hard lines
High Temp Silicone sealer
3 extra (harness side) ecu pins, get from some used ECU plugs on junk car
bolts for the turbo-to-exhaust manifold connection and the one nut (I used normal hardware store stuff, but you might want to get the correct bolts from the dealer)
copper gaskets for the lines
a whole pile of various vaccume tube, connectors, hose clamps, and an assortment of bolts and nuts(you can never have too much of this stuff, just incase)
antifreeze
oil filter

thanks for the replies guys. Sounds like I may just try to rebuild it as n/a and have a dd or sell it.

You could always rebuild the block and slap a turbo on...

 

[XMasta19]

rebuild your 420a or find a built block and turbo that bish...you'll be happy

 

[turbo2g111]

I know a place by where I live that sells lightly used engines pretty cheap (my friend bought an engine for his supra TT with everything but the a/c condensor for $400), so I was just going to put one of those in. Would those work, or would a rebuild be necessary?

 

[VelocitàPaola]

You could buy a used engine and turbocharge it, but it won't be good for more than about 10 psi. If you rebuild with forged internals, the sky's the limit...

 

[turbo2g111]

It would be nice, but I'm on a relatively cheap budget. Thats why I was looking at just trying to drop a 4G63 into the RS.

 

[VelocitàPaola]

Well if you're on a tight budget, doing a 4G63 swap is not the way to go.

 

[turbo2g111]

As I found out....
I was just trying to save some money, because I have a complete (but not quite running) 6-bolt sitting in my garage, plus all of the other random engine stuff that goes along with that, and this looked like a good opportunity to use them and take some mileage off of my TSi AWD. I may just try to put in a new 420A and sell it.

Keep the RS and use it as a daily driver. Bring the AWD out for fun on the weekends.

 

[XMasta19]

meh...turbo the RS for your daily driver
