what would it take to drop a 4g63 nt into a car that came stock with a 1.8 nt
what parts will i need other than the engine, wiring harness and new ecu
how mutch would it cost me
and what the benefits will be (in terms of modification potenitial) compared to what i have in there now.
any advice or if anyone has done this themselves, the information would be greatly appreciated.

thanks
nate

 

really the engine, wiring harness and ecu should be all, maybe new motor mounts. and if you are planning on alot of mods i would recomend a new tranny, the one for the 1.8 more than likely wont support all that much power. Of course, the 2.0 will be able to produce more power, but really the 1.8 and 2.0 should be able to have the same mods.

 

i really havent been able to find but a few parts for the 1.8 ive found a boatload for the 2.0 but maybe im not lookin in the right places
where would i be able to find mods for the 1.8.i cant find them anywhere
once again any info will be appreciated

 

Look up motor parts for a 4g93 instead of simply calling it a 1.8 Mitsu motor... Ive found a decent amount of parts for them... But I mean, the two (4g93 and 4g63) arent even really comparable when it comes to mod options or power capabilities... But theres a decent amount of mods out there for it.

 

Skip this post... for some reason it sent twice

 

dusty...unless there is something im not catching, the 1.8l is not a 4g93, its a 4g37 correct? ive never ehard of 4g93[&:]And, i have never baught from this place but i know the website carpartswholesale.corm(minus the r) has alot of parts..

 

thanks for that ive never heard of a 4g93 either but yes as you said i have a 4g37 i will check it out

thanks

I just did a 1.8 to 2.0 swap. The one I did was a SOHC 2.0, but the procedure and swap info is the same since the 2.0 SOHC is the same block as the DOHC - in fgact, I used DOHC parts for the swap.

The problems I encountered were that the 2.0 engine, although visually almost identical to the 1.8, shares no features: None of the accessories, accessory brackets, pulleys, belts or engine mounts would interchange, making the swap seem impossible.

You have to use the engine mounts and engine mount brackets from a 2.0 Eclipse - botht eh driver's side mopunts/bracket and the front & rear mount brackets. On mine, I used all of the accessories (alternator, power steering pump and A/C compressor) along with the accessory brackets off of a '92 2.0 DOHC Eclipse, but the pulleys from the Gallant 2.0 SOHC were retained. I used a Moroso Upper Radiator Hose Cap Adapter to mount a radiator cap into the upper hose right adjacent to the thermostat housing. Injectors, ox sensor, temp sensors, throttle body and all ECM-interface components were moved from the 1.8 SOHC onto the 2.0 SOHC. The 1.8 SOHC distributor was modified with a lower o-ring groove machined into the body so it would interface with the 2.0 SOHC head, allowing use of the same distributor for ECM interface. The 1.8 uses 2 oil pressure sensors, whereas the 2.0 only has 1, so I pulled one of the machining plugs out of the 2.0 oil filter adapter and used a pipe sleeve to adapt the 2nd oil pressure unit to the 2.0 housing.

The engine was installed with the tranny still in the chassis. It's a tight fit, and you have to remove the crankshaft pulley/harmonic balancer to get it to drop in. But it went in with no problem. A little wiggling to get the pulley back on the crank after installation. The engine fired right up and a quick check of ignition timing even showed the timing to be dead on without any need for adjustment. No leaks, drips or problems. The 2.0 has much better bottom-end torque, and overall performance is very nice. The installation, with everything hooked up and cleaned up, looks very stock.

Total effort was a couple of hours to pull the 1.8 out, 4 hours in a junkyard to pull accessories and brackets,3 hours to dissassemble & re-assemblethe 2.0 for installation of valve stem seals, oil pan gasket, rear main, head gasket, timing belts & water pump, and 6 hours to transplant all the accessories/brackets onto the 2.0 and install the engine into the car. Total cost came to about $600, which included the new water pump, engine gasket kit, new timing belts, fluids, radiator cap adapter, the 2.0 engine and a couple of cans of R12 freon to re-charge the A/C.
