Hey all,I am trying to figure out what steps I should go through to figure out what is causing my issue.Some background is that the car has been put together and running since about mid April. Towards the middle or end of May it started to act like it had a misfire or something. I replaced...

Hello everyone! I'm currently rebuilding the engine in my Eclipse. It originally was a 6 bolt but i swapped a 7 bolt because the block was cracked and couldn't find a replacement.I need to change the crankshaft, a con rod and con rod and main bearings, and also the oil pump just to make sure...

I am still in search of a N/A engine harness for my 1993 Eagle Talon but I was able to find a turbo harness. What all would I need to do to be able to run a turbo engine harness on a N/A engine and ecu? I’ve read just an injector resistor pack and N/A fuel pressure regulator would need to be...

Hi All,I am working on my 1997 GST and looking for advice on best course of action to take for my situation. Read below for context.You must be registered to see element. Context: Bought the car from a young guy who for some reason decided to begin to remove the drivers side motor mount and...

Not sure if this is the right area to post this. But I’m trying to gather as much information as I can on twin charging. I’m completely new to it and I’m trying to just figure it out. My main spot of confusion is how the pluming for the intercooler piping and everything will go. I can only find...

Making a lot of progress on dream Engine build, Some stats H-beam Forged Eagle rods. Wisco Forged pistons, All ARP top to bottom, BC stage 2 cams, BC cam gears, All new Accessories. OEM 16G Turbo. Billiat intake and much more. Next is fuel system. Also still looking for the middle timing...

I currently have a 1990 Plymouth Laser 2.0 RS (FWD auto). It has overall been a great and very reliable car, except for one issue: A rusty fuel tank. I know for a fact that this car has spent most of its life sitting around, so I'm not surprised the fuel tank is gross, but it's causing problems...

So I am in the proccess of rebuilding my 4g63 engine as you can all see my previous posts. But I belive I made a terrible mistake and threw away the old torque converter and flexplate thinking I could just get another one. I'm such an idiot. Anyways, is there any way I can buy one? I saw one on...

I bought this car a week ago for pretty cheap and know it runs (at least it apparently ran a few months ago). The Haynes manual has been a bit of help on a few occasions, but I still can’t find the Ignition Control Module. Right now it’s a classic case of CNS. I have air and fuel, but no spark...

I've read through the forums to do an exaust, intake, and revamp the fuel system, my question is where do I find beefier injectors for the 1.8 4g37, I've already started building an exaust system for it but I want to look into the less at home performance parts, thanks!

So my clutch died and I need to order a new one, but some sites give me a clutch diameter and other sites give me another diameter and I do not know which one to get because I need to order it from outside my country and on most of the sites I can't return it if it doesn't fit.These are the...

Recently picked up a 1997 Eclipse Spyder GST as a first project car.One of the only issues with it is that the headlights stopped working. When turning on low beams, none of the lights work, turning on high beams results in the driver side high beam bulb to work and the low beam bulb shines...

Hi, back with more issuesAbout a week ago I installed my alternator back in the car as I had it fixed, it seemed to work fine for a few minutes but when it got to operating temperature it had a severe misfire and would not accelerate unless I pumped the pedal a bunch of times repeatedly pretty...

Posting up how I wired and configured my FuelTech FT550 with the 4 Cylinder A + B universal harness and FT Smart Coils for anyone’s reference. I’m writing this out mostly in the order of the booklet for the harness (You must be registered to see element. - starting at page 14), and I’ll include...

A bit of context: the block cracked in my 92 Eclipse, bought another 7 bolt engine since I assumed mine was also a 7 bolt, being a late 92 model.Now the new engine doesn't fit, because the oil pan hits the chassis, it's a little more left than the other one. The transmission fit perfectly...

I was building a '97 GSX when I accidentally etched one of the main bearing saddles of the block while trying to clean out the oil and water lines since these blocks are getting up there in age now. I never did figure out exactly how it happened, but it did. So now I need a new block. Also, I...

I'm a bit confused what car an engine I want to buy is from. Can you tell based on the code on the block?I spoke with the guy selling it and he says he believes is from a 95 Carsima but the Carsima didn't come with a 4g63 so it's definitely from another car, it's currently on a l300 he wanted...

I’m looking into possibly buying a 1GB eagle talon. It’s a 1993. I’m curious where major rust areas are on these cars. I’m not to familiar with the 1g’s compared to the 2g’s. Any help would be appreciated!- James

Hi guys,I drive a 1993 Eclipse GS. It has a stock non turbo 7 bolt engine.A few months ago, I noticed a weird noise coming from the engine bay, which I believe to be pinging/detonation, after reading this older thread: You must be registered to see element. I can hear it during normal...

Hi guys,My name is Bozhidar and I'm from Bulgaria. I'm the proud owner of a 1993 Eclipse GS since 2016, but I just recently decided to join the forum. These cars are really rare in my country and it's getting harder to source parts for them, but I have no plans to part ways with mine anytime...

What’s up guys. I have a 1998 GST 6-speed that I’m going to build due to having rod knock. I live in Moreno Valley/ Riverside CA. My question is, do you guys know where I can get my car tuned after I finish the build. I’ve taken my car to two different tuners in San Diego in the past and have...

Can someone help me identify which 4g63 is this, I am mostly a toyota guy so and toyota has variants of each engine, so this 4g63 which I have come across, is it a specific type of 4g? If so what problems are to be careful of with this engine? And this is a stock block with stock head with a big...

I wanna peep some 4G63s, what's going on in that engine bay? Hows it look under that hood? How clean do you keep it? Hows your piping look? Do you care how it looks or just how well it works? I wanna see it all. I wanna see a well done, clean, impressive engine build.

Hi guys!I have a 2G GS (EU spec, N/A 4G63). I converted it to turbo, mostly with stock GS-T parts. I changed the pistons to EVO 8, but I left the cylinder head OEM. Does anyone have any information about the Eu spec camshaft being different then the GS-T camshaft?The car behaves normal, I...

Would it be a problem to rotate my mostly assembled long block upside down on my engine stand and leave it like that for roughly 24 hours while I reseal the oil pan?The oil is drained out and I would drain the rest of the coolant remaining in the block prior to doing so. I am, however...

Hello this might be a stupid question but would it be possible to wire some 4G63 Fans onto a 420a?For reference this is the fan i want to wire/install. You must be registered to see element.

Would it be better to install my 1220s and log maps on MAF for base Speed Density tables OR map what I have then change to speed density AND the 1220s simultaneously?

Hello, back again with trouble on my '92 Galant.A couple of weeks ago the car developed a misfire in cylinder 2. I had them serviced along with the spark plugs (they cleaned them up with a brush and a pick, nothing fancy) and the car idled as before, but a couple of days ago the misfire on...

Hey guys, just trying to figure out what’s these plugs are for. They were connected to the auto engine harness before it being pulled. These plugs are located on passenger side bottom of dash behind. This is a 91 eagle talon awd auto. Thanks in advance!You must be registered to see element...

Hi guys, i need help, i bought OBX FWD LSD and when i tear the transmission, i figured out on the LSD missing helical ring for speed sensor. On stock diff is casted with the case, but on LSD is place to put the ring on … but here is few problems - i have measured dimensions, but dont know what...

Hi, I'm in the process of hunting down and properly testing and connecting all A/C sensors, if I'm not mistaken, that would be: 1. Air Inlet Sensor. 2. Air-thermo Sensor. 3. Air conditioning engine coolant temperature switch. 4. Engine coolant temperature switch. 5. Refrigerant temperature...

Here is my video build series of my 1997 Mitsubishi Eclipse GST. I am rebuilding the stock 4G63 turbo engine. This car had 198K miles on it when it locked up. I think it was starved of oil and was slamming gears and reving high. I was raving engine when all of a sudden the motor just stopped...
