so I have a thread going over on saablink, but I figured I'd share on here too. I'm putting together a replacement engine for my '00 9-5 aero.
b234 block with a b235 head T5 cams, and a tdo4hl-19t with a 7 cm exhaust housing

this is not a genuine tdo4, this is from taiwan. I bought it on ebay. it cost a little over $700 altogether. I'm fairly optimistic about the performance of it. it's balanced and spins smoothly and easily. everything looks to be of very good quality actually.

and no, I did not hone the cylinders. it is a fairly low mileage motor to begin with. the cross-hatching was still very visible in the cylinder walls. I saw no reason for the extra expense.

Just for reference I paid about $100 less (I did have to send him a core) than that for a genuine TD04 professionally rebuilt to the highest of standards by Dave Kennedy and bored to fit an 18t, add a 6cm turbine housing, and mill the compressor housing to fit the King Cobra pipe. He does crazy stuff like machining the heat shield to properly set end clearances... I doubt the taiwanese are going to such extremes.

But good luck, some people do claim good things about the ebayasiachargers. But I personally am not buying it.

Very nice looking feed and return lines!!! I'm jealous of those

Yeah. I would have gone that route, but unfortunately I'm currently driving the car. I can't afford to have the car out of commission for as long as it would take to send the tdo4 that's on the car out to be worked on. This was the next best solution. I'm hoping if all goes well to have the engine swap done in a saturday.

Dave is great to work with... he has plenty of parts on the shelf, and at least with me (we have a good report from projects in the past) he sends me the new turbo and then after I swap them I send him the old turbo/core. With build time and shipping my 18t took just about 2 weeks. It all depends on how busy he is though at the time.

This is a kick *** build. I probably won't get to see it in person until Carlisle next year (will be my first time going in 8 or 9 years).

hmm I never really considered that lol. Oh well, hindsight is 20/20

I honestly have no need for a 19T, but I figured why the hell not? I'm really not building this to be a monster, I just knew that my current motor is on its way out (has had a slight knock and oil pressure issue for a couple of months now) so I've been gathering parts to get this thing together. I have a 225 lph BBK fuel pump that I'll probably install and a 3.5 bar FPR that I'll be installing. I most likely won't do injectors.

on top of all this, I'm not sure how long I'm going to hold on to the car for. I've been saving up for a down payment on a newer vehicle that I've been eyeballing.

worked from 9PM to 5 AM last night pulling the motor(out the top) and then from 1PM to midnight today getting the new motor in and hooked up. it runs, I have a leak coming from my water pump, and the valvetrain is a little noisy for now. I'll sort out the leaky water pump tomorrow and hopefully be able it to drive it to work on monday. I'll post some pictures tomorrow.

to clean all the rust and garbage off the block I used an air needle scaler, which looks like this...

all of the little fingers vibrate, kind of like an air hammer and it works great for cleaning blocks, then just spray it down with a degreaser, blow it dry and you're ready for paint.

for the engine paint I bought a pint of POR-15 engine paint. it was about $25 but it goes a long way and does an awesome job. it is a brush on application.
