First, congrats on your ROTM. Nice car.
Now let me answer your questions.
I am running the stock NA block and head, I pulled the engine to do the conversion cause it is easier to do. I also put the R-154 on too. I am using a stock headgasket with ARP bolts @ 80ft/lbs.
Oil lines are custom. I have a -4AN feed line off a tee from the oil pressure sender, and the drain line is -10AN. I pulled the oil pan off when the engine was out and drilled a hole, then welded in a -10 bung. Stainless braided lines. You can buy the lines from Rabidchimp.com. I think MDC on here makes them too, but if I am right, his are for a turbo block and the lines are a little shorter. I don't know if they would be long enough to go down to the pan as the turbo return is midway up the block.
Injectors are stock turbo 440's.
I bypassed the turbo coolent lines, didn't need them, just use a turbo timer.
As for max boost, I think 12-13 is about it without some fuel/timing management. I am staying with 10 for now, I have an HK$ MHG hanging on the wall in my garage but I didn't want to strip the motor down for machining this time around so to keep reliability up somewhat 10psi is max for now.
I plan on dynoing soon, so HP #'s will be up then. But the ass dyno says 287.4rwhp:biglaugh: 300rwhp is my goal. I need to swap in my 3.91 LSD then I will take it down the quarter. My goal there is 13's, but that is more up to me and my skills (or lack of) than the car!
Honestly, this is the best thing you could do to an NA. It really is a great car, I love driving this thing, and the turbo power just makes it 10 times more fun. I haven't run against any local turbo guys but it is obvious that 10psi to 10psi I will toast them!!! No lag, boosting + from about 1800rpm:naughty:
I have owned high boost turbo cars before and that kick when it boosts is fun, but this car is more driveable. This car will be used for autocross more than drag so the current powerband is better suited to that.
Do it!!!!!! You will fall in love with your supra all over again.

Cost is relative to your patience! I was in no hurry as this car is not my daily driver, so I just kept checking the forums and picked up deals when I could.
I ended up buying an 87 turbo with a BHG for my parts. I actually made money on it so this conversion cost me nothing. I got the 87 from some honduh kids that needed it gone from their momma's house for cheap. I parted out what I didn't take and sold the shell. I ended up with the R-154, LSD and block/head, and the electronics. The engine is sitting in the corner of my garage for the future. The rest is on the car now.
But here's an example of how you can do stuff cheap if you look araound.
I made my intercooler hardpipes from a honda crx intake-$15, and some mandrel bent piping from ebay-$27. About $50 for silicon couplers and clamps-ebay again. Probably around $100 total for hardpipes that would sell for $300+.
Got my 3inch downpipe and high flow turbo elbow for $120, all stainless. Just needed some holes enlarged to fit. Ebay again.....
Read above for my exhaust $$$ savings. The key is being able to do stuff yourself.
If I had to guess on your cost here's the list, and what I would pay for each:
ECU and harness $150-200
CPS $30-50
Coilpacks $30-50
Ignitor $20-30
Injectors $30-50
Turbo $100-150
Manifold $20-30
Stock intercooler and piping $75-100
Stock elbow/downpipe $20-40
AFM $40-50
So low side $500ish, high side eleventy billion depending on how many toys you buy:biglaugh:
My best advice, shop around. I have seen guys selling the whole list I just wrote for $3-400.
Here's a link to my main resource for my supra questions
www.supramania.com then "search" :naughty:
I've done so much to my car lately it is hard to list it all, but if anyone has any NA-T questions ask me and I will try to help, I certainly learned a few things this summer and would be glad to share.
