Yes, thanks. I have seen that issue raised enough now in these turbo threads to realize how important it is as a limiting factor. I am hoping to step into separate engine management as a second step.
Turbo 80 ~422hp and 631ft/lbs at the motor!

Awesome. How seamless is the FIC in part throttle and off boost drivability? Smooth like stock?

Yeah it drives great! I will try and get a video soon.
What was the actual power and torque readings at the rear wheels?
And have you got a dyno sheet to throw up yet?
Also, in post 573 of your build thread, it looks like the turbo coolant lines are plumbed the thermostat housing (supply) and heater pipe (return). Safari, and everyone else who has since turbo'd their 1FZFE, take the supply line from the heater supply pipe and the return into the outlet housing on the other side of the block (behind the dizzy). While your coolant supply point from the thermostat housing seems ok, I'm not sure about adding super heated coolant back into the engine. To me, and my reasoning why Safari have done as they indicate, it to not add any more potential risk to the cooling system, hence dumping it just before the top radiator hose. Of course, if I've not interpreted your pics correctly, I apologise in advance.

The water coming out of the turbo won't be that hot. The turbo is oil fed so much of the heat is drained away with oil. The water is there to help combat coking when the turbo is shut down. It should be fine.

The actual numbers were double the stock power and 218% of the stock torque. I don't think I will be getting the dyno sheet since the shop that did the tune and I are not on speaking terms. I called them out on an install they did on my other car and evidently they got pretty upset about it. But I feel like on a $90k car when you're doing a larger fuel pump install you use new parts and not mismatched fittings and whatever is lying around the shop and then turn around and charge me $220/hr for the job. But anyways the actual numbers don't really matter as much as its the difference between the stock dyno and the post dyno that matters. And that was 199% of stock hp and 218% of stock torque on the same all wheel dyno. I am sure I could have disconnected the front driveshaft, locked the center diff and made it look like more power, but again it was all wheel before and all wheel after. Peak HP @3550rpms peak torque @3400rpms. Post dyno being done in worse conditions, on a hot day. And just to clarify it was not EMS that did the tune. The shop that tuned it, their tuner is great but their mechanic lost my business.
I will do some 0-60 pulls once the transmission is done and that will be an easy way to validate the additional power.
Thanks for the heads up on the water lines I will take a look at them. EMS routed them just like they do on the Supra's, we talked about it before they did it but I can see how dumping the hot water back into the engine and not into the top of the radiator would be marginally worse. I will also go for a hard drive and check engine temps if it doesn't effect engine temps I probably won't mess with it. Maybe throw an IR temp reader on the fittings and see how much hotter the return is than the feed. Thanks for the idea.

Wow, impressive numbers! I would love the be "surprised" by your 80 as you pass me on the highway... so unexacting!

Oh I realized I never followed up with the dyno sheet. Here is the link to a twitter post the shop posted.
Blue is before, stock with upgraded exhaust and red is after with turbo

Might have been covered but what would something like this cost? Looks great and sounds wicked!

I think now that I have done it once, I could probably replicate it for around $7-8k. Not including the head rebuild and head gasket, etc. The actual turbo system, engine management and transmission. I think I spent about $14k doing the R&D.

7-8k you may have come people wanting it done in their Cruisers! It will be interesting to see how the transmission holds up. Will it be a daily driver or would it be ok to driver as a daily?
- Thread starter

Oh yeah I could drive it daily, I don't but I do drive it at least 3 times a week and I don't baby it. I love romping on it from stop lights and chirping the tires. haha. I think the trans will be ok, it won't last 300k miles but it doesn't seem to be glass either. I have put 4000 miles on since we finally got it dialed in, and I have never noticed any issues after I had the trans gone through by Boost Logic's guru. He says it should be safe to 800hp.
Oh and I am not building these, but I can certainly offer all the advice I have learned along the way.

800hp? Not being a d*ck but I know he is way off his rocker lol... The stock Supra autos do not even hold up to that much power. Bowtiestang has a 1996 Supra and says anymore than 15lbs of boost he can cook autos all day long 
. But I think its badass what you have done I like it. If I wouldnt have put a LS motor in my LX Id be right along with you

Stock supra transmission is an a340 same family as the 80 series. Stock they don't hold that much power, but Boost Logic and Titan both have them holding 900+ I trust the guy knows what he is talking about, we did almost everything except for the billet parts that are only a340 compatible.
Boostlogic has changed their website but here is the link to the Titan trans.

It annoys me to no end that a built Supra auto can be had for $2200, but if I want a built a442f I'm looking at $5k from Wholesale Automatic.

Yep its an economy of scale, not many people want a built 442 lots of supra guys want a beefed up auto. Lol

I don't even see a Transgo shift kit offered for the 442, so looks like your only option is Wholesale.
Livin' @ 6000 ft., I'm green with envy!! What a beautiful, sanitary install !!! Nice work, and ALL Toyota!!

This result makes me wonder why there wasn't an OEM option for turbo on the petrol version, unless everything wasn't "quite there" on the R&D back in the 90's?
- Thread starter

I think the reason it wasn't offered as an OEM option is simply that Toyota favors longevity over power, it can be seen in all of their vehicle lines. 22re in the truck, 3.slow in the 4 runner, under powered but long lasting inline 6 in the LC's. When you start adding a lot of power other things require more maintenance and upkeep.
That and cost, for a truck that was already at the top of its market.
