Sorry for my newbie question. How come your boost dial is running on the wrong way? Is your turbo creating vacuum?
Turbo is in!

What size waste gate are you using? Running same turbo but my 38mm Wast gate is not allowing me to trim low boost properly. Will be changing to 50mm waste gate.
Also running same GT35 with .70 getting 212kw and 603nm on the wheels.

Very nice install. Research and patience pays off. More power is always nice, especially with these pigs.

Yes, I track fuel mileage every tank, I always have and always will. Prior to the mod I was averaging 10-12 MPG on country roads and could Maybe get 13 on a highway trip. Post turbo I am running the same if not more like 11-12 MPG. I played with octanes before the turbo and found no gain in performance or mileage, I only run high test now because of the turbo.
Bottom line is that I see no change in MPG's. There is a huge difference in how much the pedal is pushed down at 65 on the highway. I'd love to hook up my scanner and compare throttle position with a NA rig at 65 on the highway.
I hauled my boat with it last spring 1000 miles and averaged 10-11 MPG going 65-75. I was elated that it was getting over 10.

I am running a 38mm WG. When it was first installed it had a 8 or 9 PSI spring in it which was giving me WAY too much boost AND the inability to control it any lower than the spring rating. I'll ask you first, What size is the spring? because you will not be able to control boost below that...
The second issue you may have is a diaphram leak or a stem leak on the wastegate actuator. This can be either fixed or a 'bandaid' applied by plumbing larger lines to the wastegate to over come the leak.

Yes, the turbo came with one and it is installed. I do not know the size.
Ok, so to be clear, I am not very technical. You are running a turbo application on the stock computer, injectors etc...albeit on a low boost. You did not have to remap or change to higher flowing injectors etc...This is amazing news. Almost makes it feasible to start putting together a parts list now. Thanks for all of your help.

Ditto the above....thanksLove it. Looks tempting. Have any idea of an approximate total cost?
Thanks!

Apparently Jet can, good luck finding anyone who has done that though.
Treadstone manifold runs around $400-$450 new and it's still readily available. I can't find the turbonetics manifold still available anywhere, but when they were they were around $600 (also turbonetics has a T3 flange, which is more desirable for me, but probably not for most). The only other widely available manifold is the CX racing one, which is tubular, not cast, and may not hold up too well over time (read bouncing around off road with a heavy turbo on the end).
There is a mud member who used to make a "J-pipe" that turned your stock exhaust manifolds into a turbo manifold, but I don't know if he's still in the business. His website is down.
$420 for the treadstone manifold assuming they actually have it in stock:

Ty Saxon is selling the J-pipe setup that he inherited when EMS went under:

Tubular exhaust manifolds don't generally have a good reputation (at least in the MR2 world). I would stay with cast myself.
I am really tempted to do this with my truck, but at 211k I'm a little bit leery.

I'd love to do it with mine. But I've blown a piston out of an engine before and now I'm very timid when it comes to boosting engines that really weren't designed for boost. I know the 1fz is not your everyday engine though.
Treadstone MAF on mine has been fine for nearly 30k miles now. Running a nearly identical setup to the OP, but upgraded injectors, Supra fuel pump, and step colder plugs. Good thread here and I'm not sure why more people don't Turbo their 80s. I've been very happy with mine.
Wouldn't it be fair to say MOST engines weren't designed for boost unless they came from the manufacturer that way? I think the 1FZ is plenty capable of handling some minor boost if done correctly.
Well let's add some clarification, some of the parts must have been used. Because there are no Garrett ball bearing oil and water cooled turbo's that could come in at that price point. Then you add BOV and wastegates and your going to be considerably over that number. I have priced out a simple system for several people via PM and your really looking about $4500-5000 in parts plus installation.
Thats alot more than $1500-2000........I guess time to start doing some research.

Well, let's also compare apples to apples. What are you including in those numbers for installation costs? Parts prices are pretty fixed if buying all new. Labor is relative to what's available in your area and location.
I'm sure 90% of people looking to do a simple turbo setup like this are probably going to do it themselves.
That is just parts, that's why I said "$4500-5000 in parts plus labor"
