FRCEF3D Mits build thread 4G63t DOHC swap/vr4 big brakes/air bags

[DroppedMitsu]

The FSM's are all over ebay for $10-20. There are two for a vehicle; body/mechanical and electrical. I definitely prefer the fsm over haynes and chilton as I have them all. The factory sm is way more detailed and has more info. For the 4g63t as stated you can buy an eclipse, eagle talon, or Plymouth laser as they were all the same car. Make sure to get a fsm that is for the same year as the motor as they changed little stuff around quite often. 90, then 91-92.5, 93-9whatever etc.. You preferably want 90-92.5.

Ok thanks. Now I'm 100% committed to doing this swap I'm currently saving up for it.I wanna know what would be the best way to do this financially and mechanically? Should I buy a used 4g63t that comes with everything wiring ecu ect.and rebuild it.(send it to a specialist)or buy a crate engine and search around for everything that it doesn't come with?i come from a small town in Hawaii and its almost impossible to find parts down here! So purchasing a used one after shipping comes out close to what a crate one costs.But the crate engine doesn't come with everything,so I'm stuck on this part I just wanna make sure I spend my money right for this.SHARE YOUR THOUGHTS ON THIS!

[Natedog]

I'd make a list of everything you think you need, and look online for pricing, then compare that with the cost of the crate engine is. You might could buy a JDM galant import engine with harness and such for your needs and be better off. Many times these are low mileage, and come with most of the wiring harness, ECU, etc. Sometimes they cut the harness so be leary of this in your search (you may be able to use the cut harness and wire into yours though).

It really depends on how you want to go about it, and how much money you have to spend. You may do better to just keep your eye out for a DSM and buy it on the cheap...

[Ram50808]

I might have found a 4g63 eclipse motor still waiting for the guy to get back to me.he did say its a non turbo just waiting to find out what year. If it is a from a 90-92.5 eclipse is it worth buying and then buying a turbo kit or should I just look for a motor that's comes with turbo?

[Natedog]

It can be done, the pistons and cams are different on the NA ones. As well as the block doesn't have oil squirters... I'd just wait and get what you need.

[DroppedMitsu]

I'd definitely wait for a turbo motor, its always better to start off with the right stuff from the get go.

[Ram50808]

Yah definetly makes more sense to get a turbo one! How can I identify a non turbo from one that has a stock turbo?

[DroppedMitsu]

Driver side under intake will have hexagon sensor in block, that is a knock sensor which only turbo motors have. I'll try to think of some more ways to identify and let you know.

[Ram50808]

Thanks man appreciate it

[DroppedMitsu]

I guess the n/t blocks are tapped for the knock sensor but in a slightly different location.
Some other ways to tell:
Water pump pipe doesn't have outlet right behind wp for oil-water cooler
Lower therm housing doesn't have spot for oil-water cooler line
Back pass side of head blocked off where stock turbo oil line feed would go
No spot on pass side of oil pan for turbo oil drain(easiest way to tell I'm thinking)

[4doorciv]

Oil pan would also have a return line from the turbo. Cheapest route is to find a running parts car with damage. Emphasis on running. Lol. Dealership quoted me $350~$400 for an engine harness few years ago. Cleaner you want the install to look, expect to spend more.

[Ram50808]

I didn't know u can get a new wiring harness from the factory?

[4doorciv]

Mitsubishi dealership. These cars have been obsolete so inquire if still availible.

[Ram50808]

Ok I'll try giving a call

[4doorciv]

If you get a cheap donor car that runs, you will have almost everything you need. Just need to buy a clutch and intercooler piping, that's if you have the km132 5 speed trans with the 2.0 engine.

[Ram50808]

Tahini hoping to get a cheap donor car but being in Hawaii it's really hard to find! There is this salvage yard that I contacted in the mainland that could send me the motor,wiring,ecu,ect! So that might b the route I'm looking at if I don't come across a cheap donor car!

[4doorciv]

Weird. I'm on Oahu and was able to find one for $900. :s keep your hopes up and be patient.

[Ram50808]

Yah Oahu has way more chance of finding a donor car then big island there's a few here in Hilo but nobody wants to sell!i actually had to get my 89 ram50 from Oahu because everyone down here just didn't want to sell theirs! Next time I'm on Oahu ill try looking for one, maybe ill get lucky in the mean time ill keep praying to find one.

[4doorciv]

If it comes down to it, thedsmgraveyard.com has motors ready to drop in. Be advised they have some negative feedback since they opened. Maperformance sells blocks and heads but not complete. You might also get lucky in dsmtuners.com/classifieds. Lots of people part out their cars instead of sell as a whole.

Here's what I've been working on lately, a big brake kit for our trucks. I'm going to be using 3000gt VR4 4 piston calipers and 12.5" rotors. I've almost got it finished, I have my test bracket made and it all lines up pretty good, just need to make my final version for both sides. I'm planning on making a setup for 6-lug too as my buddy plans to keep his truck 6 lug and wants a kit. Hit me up if you guys have any questions.

Hi Josh...How are you going on the brake upgrade? I am in Oz and have been doing some research on this but striking blanks everywhare with rotors etc. I tried to resurrect the Big Rotor thread to see what people have come up with. I have been in contact with Rahtid and he has shown me some of the things that he has done...he is still trying to find some rotors...Fishpost19 is in Australia too but his is on the back burner at the moment due to other projects getting more of his attention and money... I am interested in 6 lug like your friend...I have a 2WD Macro cab (club Cab here) like yours and want to do a front disc upgrade...would love to know if it has progressed to being available soon...
A place here in Oz (hopper.com.au) have a 300 mm kit for L200/L300. I rang them and asked if they will fit the 2nd gen trucks like ours...they said only if the stub axel was the same on both the first gen and the second gen....do you know if it is? Theirs is a 5 lug kit using Ford Falcon (aussie made) calipers and I think a 5 lug Commodore disc and a conversion hub that is custom...That is all I know until I can confirm whether the stub axles are the same or not...

cheers

I have barely got my big brakes setup. I still need to do the driver's side. I do not plan to sell any kits or make a 6 lug any time soon. Merrill on this board might be of more help as he has a shop and more resources as well as also building a big brake kit

[pennyman1]

Thats a good start, but you need to get a caliper that will use more of the rotor - that one is too narrow and may cause unwanted side loading of the caliper brackets due to the tendency to fling it off the rotor at high speeds. More pad surface area means better braking.

[DroppedMitsu]

The rotor is using all the pad surface area, but I understand what you are saying and already thought about that. Also the rotor is only .5 in diameter bigger then the stock 3kgt rotor. There is another guy running a similar setup on a Toyota with no issues. If these calipers can stop a huge and heavy 3kgt then it should have no problem with the truck. If anything I'll go down to a little smaller rotor later on when I go with a custom Wildwood rotor and hat combo.

[BradMph]

I like this mod, though I kind of see what Pennyman is explaining. I can see both views though, but the photo sure looks like you could use a larger caliper to utilize that enormous rotor disk space area you have.
The small issues I see are possible balancing of the rotors and the bearing dust covers and heat buildup. Those 2 extra holes drilled on rotor hubs must be a balance drilling right? Another question I am thinking...are those rotors vented rotors? From this angle I don't see the inner vents and that's why I asked. If the rotor are not vented centers... are you going to install air vented dust covers to help cool them off? I think the 6 lug would be a great idea since the trucks are 6. All in all I like the mod, especially with that massive rotor surface area.
