Hi! Im looking for a 1uz engine block. Best regards, Kristian

It is 93 octane, Im running dual ITS 61mm turbos. There is no problem with 25psi of boost. Compression ratio is 8,4:1. I have done some work on the combustioncambers. But it should´nt be a problem even with stock cambers. Im at work right now and a little short of time. I will tell you more later.

=) well then, tell me what you want to know and I will tell you. ;)

Hi there! To begin with, Im okay! Im also very happy to see that you like the car. For you guys that dont know about the car. It is an Ultima GTR with a twin turbo Lexus 1uzfe engine. 4litre displacment. Im running the car on pump gas. It produces 962hp at max boost (arund 1,7 bar). In the...

If you have camshafts with hight lift (~10mm) you will have to grind/machine the center gear to get it on.

I´m reving my 1uzfe to 8500rpm

Yes! thats right!

I did about 20 900hp + runs and alot more on 16psi (820hp). We used a total of 150 liters of fuel so the engine was running quite hard during these days. As soon as I got home I took everything apart. The pistons and everything was like "new". I will now put the engine back together and run it...

Well, my plan was 1k. But we I some small problems, thats why I stoped at this point. I will break the 1000hp limit later on when I get some more time and money.

It is 960hp @ about 23 psi. It made 820hp @ 16 psi.

Im using a Porsche G64 transaxle from a 993 turbo.

You cant realy use factory specs if you are using the ARP studs. I was just curios what torque you guys use. Not a big problem at all..

Does anyone know the torque to use for lextreme ARP head studs?

The pump itself cost about $1000. Then you need a tank, thats about $400. You also need the drysump oil pan, I made my by myself so I dont know about the cost. And finaly all the hoses =(. Dont underestimate the cost of braded hoses (atleast in Sweden) I will post a movie as soon as the snow...

Thats right! But I live in Sweden. We can actualy get 99RON on shell stations. But mine is fine with 95RON octane.

Yes, it is in a engine dyno. Regarding the glow, you have to have in mind that it produces over 820hp and 7500rpm in that pull. I didnt have time to film the 961hp/8500rpm pull. Im realy sorry for that. I will scan my dyno-paper tonight so you can see the power curve. BTW, it felt that...

I finaly got i finnished and dynoed! 960hp and 1060Nm(1060Nm = 782Tq) on pump gas. I will post a small movie from the dyno later on.

Its is a streetcar. The car is not 100% completed yet. But it will be street leagal. I still have a few more things to clear before getting it registred. I will also take the engine to a dyno soon So I can tune everything. It also feels nice to know how much hp you have :smile:
