Whats up im still kinda new to the Eclipse and Turbo World. I jus got my 95 GST! and i've done my research for the car. (Thanks to this fourm) but im still stuck on one thing. So heres my question


Over all, how dose the 4g63 engines hold up, is there any problems that every one has? Should i expect somethin, the motor i have has 65k miles, and the guy i bought it from said the timing belt broke, so you fixed it and rebuilt the whole engine. Pistons, rings, valves, everything.


So should i worry to much about it?

The only thing that you might want to worry about is the balance shaft belt. At times the guys who is rebuilding the engine over look at that belt and don't change it and soon that belt will brake off and will kill your engine again.

When did it break?

Basically your job before you mod the car is to make it like it just came off the showroom floor in 1995. If you replace anything use Genuine mitsubishi parts, OR upgrade.

if you need new struts, don't wait upgrade. Don't be like but I really want an Exhaust so I'll buy half decent sturts and an exhaust. Go out buy good parts and the car will not let you down.

Basic maintenance is a must. Timing belt start thinking about it at 105,000 miles get it done before 115,000 Theres a whole service involved. Its the 60k tuneup.

change the oil. the plugs and wires. flush coolant. normal stuff.

he said the timing belt broke at 60k. so he pulled the engine and went ahead and rebuilt it. struts and things like that are no worries right now. The car is really in great shape. I jus wanted to make sure im not gonna get blind sided by somethin serious! I plan on changing the oil, plugs, plug wires (any recommendations), all that on tues. I good when it comes to keeping up with the maintenance thing.

Also, the car has some good parts already on it. NOthin major. but has an HKS turbo timer, and a Injen Intake.

another question? does a stock gst have a side mount intercooler? or does it have one at all?

If its turbo YES it does have a side-mount intercooler.

Have you poped the hood yet? There's clearly intercooler pipes going to the smic location.

lol, yea but i really haven't payed attention. I was jus happy its turboed! lol

:00000732:

well where do i begin lol

my 4g63 motor is holding strong for having 150,000 miles on it.

some things to consider to start replacing soon before you hit 100k

check master cylinder
timing belt
water belt
motor mounts!!!!!!! those things are shitty after 150k is on em
axels are a must to be replaced

other than that dude its a very amazing motor to have. they can make serious power if you do the homework and think about ways to make it run great if its a daily driver.

if your gona go into internal work man, save up and get a 4g63 motor to build then throw in cause if its your daily driver, i can bet your gona be spending alot of time in the garage if you have one every weekend ripping and rebuilding your motor. poke around cause i know sites where you can find the JDM 4g63 non turbo motor for only 600 bucks and its like 170hp stock so get a motor to build and then rip everything apart then replace the pistons ods valves etc etc etc.....


its funny because i just told you my build lol thats my whole situation and what the hell ive had to replace/check out

good luck man best of luck

I hope he did think those pipes was for the coolant...... somehow my old man did

****, when I got my car at 130,000 miles, the timing belt had never been replaced. That was the first thing to happen. Apparentely it was worn THIN. I guess that was lucky...

thanks man, and thanks to everyone else thats commented. I'm sure ill have many questions later on. Also, i forget to mention that the motor mounts have been replaced with poly somthin motor mounts? idk if thats good or not.

you got the prothane inserts....they just stiffen up the motormounts....are they like red and appear to be like kinda rubbery? if so you definetly got prothane inserts.

yea thats them. are those good to have? :puzzled: :puzzled:

Yes. It helps control wheelhop. Last thing you need is a snapped tranny.

yeah what the dude above said and this also it straightens your drive train and doesnt move your motor at all cause it holds it firm. i got some new motor mounts and i noticed a hell of a difference when i would shift. still needs one replaced but 3/4's good for now

lol, yea 3/4's is better than none, but im sure you need to get that taken care of.


Whats a good front mount for A 95 gst? and will i notice a difference?

i just got brand new oem ones cause hasport discontinued motor mounts for my 93 eclipse

okay heres how you'll notice a difference and you should try this. like chill at a good speed, then just smash the accelerator, and if you notice the jerking back and forth if you do it a few times then your mounts are shot. usually your motors suppost to be nice and firm whenever you decide to smash the accelerator, not sound like tis going to fall onto the road.....

I think he wants a front mount.

How does 320 shipped for the kit? Core and piping included. Bolts right up.

PM me for details.

Actually Im going to put together a group buy. so check out that thread.
