I had my car out and took it around the block for the first time since the swap and it was fuckin awesome. I still have a few loose ends to tidy up, but overall it's roadworthy. The car is actually reasonably quiet, which is nice. Boost comes on pretty quickly (no idea what RPM since I have no workin tach), even at part throttle but I didn't push it much all in my neighborhood.

Coilovers, bushings, and brakes are going to be the next big priorities considering it's all totally stock and 24 years old so it feels like I'm driving on marshmallows and pudding. mmm, pudding.

Anyway, I'm fuckin psyched to actually drive it.

Here are a couple more random pics.

I got my soarer 1JZ for $1750 Canadian, but all the labor was done by yours truly with a bit of help from my friends and some occasional guidance from my dad.

Just got back from a few shakedown runs. All I can say is fucking awesome. AFRs are really happy, in boost running between 10.7 and 11.7 in boost, around 15 at part throttle cruise. I still don't have a working tach but it's not too laggy, I'd estimate I have 10psi before 4k, wastegate opens at 10 psi (at least shows 10 psi on my 30 dollar mech. boost gauge). The screamer isn't nearly as loud as I was expecting, but I haven't been outside the car when it's open so it might be a little on the loud side. So far I've only hit boost on a straight in second gear and gone through second and third a few times but it's hella fun and doesn't take long. Gonna go drive it some more now. Expect pics and video up tomorrow unless it's raining or it blows up tonight.

well, that didn't last long. went to head out for a drive and heard what sounded like compressor blades contacting housing for a second. it stopped, I kept driving. hit boost once or twice and all of a sudden the car got loud so I headed home. it drive ok but doesn't make boost and the compressor wheel has definitely been hitting the housing. Time for a new holset. Fuck. Also time to get drunk.

When I bought the turbo on ebay (in unknown condition) there was no shaft play. After pretty extensive research I decided to put a 1.5mm restrictor in my 5/16" oil feed line to limit the oil feed pressure to an estimated 30-40psi. I think either the turbo had a plastic "bearing" in it, it had a bent/damaged turbo shaft, or the restrictor fucked me in the ass and now I need a new CHRA (center housing rotating assembly)

Here are the pics of the damage.

I just found this on my thread on Realhomemadeturbo.com I thought it was so funny that I had to share it.

"Last time I saw a cressida, it was in a picture, in a cops hand. He was wondering why a car with my bro's name on the slip was abandoned in a city-owned swamp, just after a man-made jump, with 2 blow-up dolls and spray painted w/phallic symbols. I didn't think he was serious at first..."

To re-phrase my previous hammered-drunk post... I went out last night, did a big burnout from a stoplight, first gear spin, second gear spin, third gear bang... spider gears in my diff shattered. I managed to limp the car home while the diff gradually ate itself, sounding and feeling worse and worse. I knew the diff was going to be the weak point when I built the car. The 7.5 inch F series diffs are only good for around 300 horse/300 ft/lb and I'm assuming at 13psi I should be making right around 300 rwhp. I just didn't think it would break that soon and that easily. As one of my friends said last night while I was drinking my face off and mourning the loss of my diff, it always comes in threes... The bottom bracket on my fixie is fucked, my hard drive died on Thursday night and on Friday I go and blow up my diff. Yay me. Now I'm hung over.

Damn... My empathies. At least it wasn't your own fault like cracking carbonetic disc before it even gets in the car.

Also, I think that I'd like to save you from a 4th trajedy. I had my cone filter right where you have yours. Mine melted... Don't let it happen to yurs. Get a pipe. You need it for a catch can anyway.
No.

Thanks for the sympathy and the heads up jacob. I've gotten my car pretty hot and driven it for a couple weeks so far without any problems with the filter melting, but I do need to put in a pipe so I can plumb in my catch can. My car's been sitting for a week and will have to sit for at least another week until I can go pick up a MK2 supra diff from a buddy about 2 hours away.

make sure you fix the backlash in that diff so the teeth arent slamming into each other.

I replaced the diff today and fixed a coolant leak that I'd been meaning to fix for a while. I got a used high mileage stock LSD (that actually works, unlike my old one) for $50 bucks from a guy a few hours away. I hadn't driven the car in the wet before and damn is it hairy with a decent LSD. In 4th gear doing about 110 if I roll on the gas and get up to about 7psi the back end will break free, and since my suspension is made of marshmallows it doesn't do it in a nice predictable way. Time to start manwhoring so I can afford to pay for new suspension, wheels and tires and pay off my student loan and other debt all at the same time.

Putting the battery in the trunk was my original plan, but when I did it I didn't want to pay the $150-200 bucks I was quoted by 3 different welding supply shops for enough 00 gauge cable to do it properly (and add 60lbs to the car), so I fabbed up a battery tray, bolted it in, and bought a civic battery for $30 bucks because it was small enough to fit and went to town. It's one thing I might redo, but it works and it was fuckin' cheap.

why didnt u go to an audio store and get x number of feet to run it? the only only long wires are the power and then the ground it grounded in the back anyways. Prolly also gotta run the smaller gauge wire to run the accessorys and stuff too. My power wire is on my starter then the other smaller gauge is to the ecu/fuses/peripherals. I think I paid maybe 50 bucks in wire? and its thick, I cant remember what gauge. Then you can fab up ur own box or get a generic box from a local parts store for like 30 bucks.
