Newly discovered 3uz engineering info!!!
So I was surfing the old interweb on 3uz info. on fuel rail pulsation dampers. Came across a forum on lextreme that breaks down the difference between the 2000 gs400 1uz engines, and the 2001 gs430 3uz engines. I'm not talking about the pics between the connecting rods or anything im talking measurements down to the intake valve diameters. More importantly!!! Found out the crankshafts in the 3uz are forged and so are the connecting rods. yes they look thinner but if their made of a more tensile strength material than hell ya'. the link to look for those interested is http://www.lextreme.com/forums/3uzfe.pdf It makes for very interesting reading.

You are correct and that is why I said "depending how you drive it" but you must know that there are a pretty decent number of guys out there with boosted 1UZ motors who have blown them up by trial and error.
I think that as long as you've seen the same material I have to support the concern over breaking the motor (primarily the rods and the sleeves) then you assume the risk and will not be surprised or angry if it breaks.
Seems that the general consensus amongst 1UZ guys (there are lots of guys out there with plenty of experience boosting them - the 1UZ is definitely a SOLID performer boosted) is that the later VVTi bottom ends are not reliable much over 400hp.
I applaud your work here because I have long thought about how to go about doing it and have yet to come up with a design I like (I am close though). I do not want to do or say anything to criticize or deter you from your project, my only motivation here is to prevent disappointment when (or if) you break the motor - I've seen it happen before, guy spends his time and money building car, car blows up, guy hates car and life - gives up.
Sorry if I sounded like I was just talking **** I guess most people here don't know I have been building turbo setups now for over 20 years and I have seen things done just about every way conceivable, some worked, some didn't. Yours works.

Too any and all gs400/430 owners.
Lets say that I decided to remove everything I've installed on this 02gs430 of mine. sell the entire kit with fic8 and tune and everything. new turbo, intercooler all piping tial blow off valve, ceramic coated manifold, 550cc nikki injectors, turbine style walbro pump, you know. EVERYTHING. I wonder who would be interested and what kind of offers would be made if any.

turbo gs430
Looking back now I jumped ship on that build prematurely. The reason why is because the aem fic8 was the biggest pain in the but. It just wasn't sophisticated enough to be a daily driver. It didn't have cold start fueling control and the extended crank was the deal breaker. I should have just saved up for a motec or other standalone but then would have had problems with emissions testing issues probably. also should have put in a high stall converter. if those had been done than that car would have been un ****ing stoppable. it really was fast as hell at wot when 13psi was being shoved down the 3uz's throat. when I was rocking the five psi. spring in the wastegate, the tires would start breaking loose as I was accelerating in higher rpms. moral of the story.

DONT RUN AN FIC8.

badblackgs, what did you do for the turbo oil drain and how did you run your exhaust after the downpipe? Did you just replace the stock fuel pump with a walbro?

It is a good tuning tool and we use it on some cars with great success - not to say it wasn't a real pain to get used to.
The extended cranking time can be a pain with many standalone's too.
I think if I were to do it I would stick to 5-7 psi.

factory fuel control???
Angus!!! So heres the deal. sitting here thinking about how to reforce induction my car but not go all out like I did the first time, I had to think about all the things that have to be altered when forcing more air into the engine. so lets say that I slapped on some kind of whipple style supercharger on top of the engine. like from a ford cobra m112 or even a ctsv caddy supercharger known for their large displacement. ok so the supercharger is grafted on some how. slight modification and a belt is matched up to fit. and the throttle body is installed somehow, than injectors of similar flow rate to factory with high impedance resistance for stock computer. now for the most important, fuel. I went back and looked at my fic8 setup window and gauges for fueling and maf map. I discovered that the factory mass air flow sensor was under control all the way up to 8 psi. which than the fic maf clamp took over. so what that tells me is if I had a supercharger with the factory computer than I could in reality run about 7 psi on the risky side. But!!! I wonder what the air fuel ratio would be when boost is being made. also, to make things even more simple and responsive, since an intercooler wouldn't be in the mix. spraying some meth injection with a window switch that kicks in at about 2psi and up. therefore knock would completely be under control. If it wasn't for the fic8 I would have kept the turbo cuz it was sick at wot. so these are some things I was thinking. I messaged blue lex and asked him if he had an air fuel ratio reading on his car (trd supercharger gs400) under boost.
