I bought myself a '91 GTS-T rb20det as a 2008 Christmas present and replacement car in December, and it's time to start working on it. Compression was bad in a few cylinders, leaks all over the place, a rattle from the power steering pump...so everything's coming out. Here's what I've got so far, I'll be updating it frequently since I'm just starting the engine rebuild. Feel free to let me know if you see any potential problems or parts I should consider replacing:
Here's my baby (Lucy). She needs some TLC but nothing that can't be made perfect
Just after the compression test:
There's my little turbo!
Turbo coming out, this is the first time I've actually seen it. I thought it'd be a bit bigger, might get a new one. Look at that nasty power steering leak. Gross.
The exhaust wheel looks a bit worn but not too awful. Correction: Thrust bearing is shot. Crap.
Why the heck is there a Mitsubishi logo on the front of my cam?
That's all for now! Power steering pump will come out in the next couple days.
Update:
Got the leaky hoses off the power steering reservoir and pushed the pump out of the way.
Took off the exhaust manifold and found some problems: Gasket is broken and cooked, and the manifold and block are black from the bad seal.
Most disturbing, the bolts came off the manifold so easily a 10 year old could have twisted them off with a small wrench. They are also worryingly short-threaded. Do your manifold bolts look like these pics or are mine just wrong?
Fan and radiator are out, stupid fan pulley bolts wouldnt loosen because the pulley kept turning but i prevailed in the end.
And after alot of reaching in awkward places and scraping of the arms, the top half of my intake manifold was removed, with the exception of the throttle cable (trying to avoid removing that if possible since i can just push this out of the way)
Okay, after a few more hours of getting crap out of the way I'm at this point right hurr...
LOOK HOW DIRTY THIS THING IS! Definitely time for cleaning and new seals.
Charly's helping out apparently.
And this is how the engine bay looks as of today.
A/C needs to be unbolted from the engine block, and a few more wires and hoses need to come off but it's almost ready! Thinking black edges fading into white for the engine bay paint job.
Just got my new dead pedal in the mail today, courtesy of EliteGTR. Thanks dude!
Engine's coming out today! I hope...Anyways, car's up on jack stands, engine oil's all gone, about to do the tranny oil. Electrical connections are off the tranny, shifter's out. Here's where I sit at the moment.
Engine's out! Thats a damn big fish!
And after a day of clean-up, it's time to start tearing the engine down. Here's what we got done over a few hours today. Tranny taken off and set aside, clutch and flywheel off, head is off, pistons out, crank is still in. cant find the socket i need to get the crank pulley off. AND THERE ARE PROBLEMS! 2 of the cylinder walls have some bumps in the middle which you can actually see just looking down the cylinder. Cylinder 6 piston looks kinda cooked. Once it's all down, it's time to send the block to be dunked, cleaned, and checked for any cracks. Looks like it's going to need to be rebored and get new pistons! boy howdy.
After a few days spent with my lady it's time to get back to the car. Took out the cams today, a couple of the bolts holding down the cam brackets were a bit iffy. a few of them don't come out of the bracket, they seem to be unscrewing INTO the bracket itself. Taking the valves out tomorrow, and maybe the crank if I've got time before work. Check this out, one of my exhaust valves is COOOOOKED. Here's a pic of the normal valves, and then of the valves on cylinder 3 or 4 (don't remember which it was). Any thoughts on what might cause this?
Got some parts degreased today, definitely need to sand and polish
Did some more work today. Finally got the crank out, but since the timing gear wouldn't come off i had to drill the oil pump off. Hillbilly solutions to the rescue!
Well the engine's entirely apart, ready to send the block off to get dunked, cleaned, and checked for any cracks or internal structural problems. There's engine pieces lying all over the floor, under the car, in the trunk, but I've managed not to take up the other half of the garage.
I tried sanding a few parts down to get all shiny and ready to polish but failed lol
Trunk's filled in and primered, ready for paint!
Bought a power sander today, reeeeeally helped get the rest of that powder coat crap off my cam covers. It's also made prepping my engine bay for painting a heck of a lot easier.
Special order engine paint came in today! Sexy hot rod electric blue...
Here we go, got my strut bar in a couple days ago, just test fitted it and it should work!
Hopefully all these colors won't look too bad when it's all together, otherwise the strut bar might have to get painted.
