After some testing and increasing the boost to 1.5 bar, the HKS twin disc clutch slipped. So I had ro uprade the clutch system. Why not building a custom quad disc clutch? This quad disc clutch can handle about 1800Nm. :-) I had some new HKS discs laying around. First step... Second step...need...

What about fuel pumps? I have good experience with the 450L/h Walbro fuel pumps. So I did some mods to add two of this E85 ready Walbros into my fuel cell. I still running only one of this fuel pumps at the actually power level. It's awesome what this fuel pumps can deliver. If I switch to E85...

I take a picture of the two fuel maps, with custom short runner intake and one of the OEM Intake. Target AFR are the same in both maps. As you can see, the custom intake fuel map is very flat and peak VE is at about 6800rpm vs 4800rpm with the OEM intake. It feels like you drive with no or very...

Yes, you can easily unbolt it. But it's not easy for me because of the downpipe etc. Check the net for the 2jz hub for example. ATI part# is 916023

Intake in engine bay... ...with IAC... ...and piping and twin 50mm TIAL BOV... System is running... ...later with new radiator... and stock intake... That's an actual picture

The diameter of the crank end is exact the same like the 2JZ. But the 1UZ crank end is too short for the 2JZ ATI hub. So you have to find a way to bring the pulley on the needed position to drive your steering pump, alternator etc. That's why I build this adapter. I have to think about it again...

Inside view 90mm TB welded... another view... another inside view

I told you from my custom intake manifold which performed very bad. I will show you some pics of the fabrication and maybe you have an idea why it's so bad. I think it's the runner lenght. It's only about 70mm to the surface of the heads... It's not a peace of art but it was only a test...;)...

Here are two pictures of the adapter. If I'm right you need a longer bolt too. From the 2JZ... There is a groove in this adpater inner hole for the crank tongue . And I installed another tongue in this groove too for the ATI hub... I hope you know what I mean. If not, I could do a little...

That is awsome. The 1UZ is a very good choice and I'm happy to own a boosted one. :p

I have build an adapter. I have no pictures of this adapter only. But I have pics of it installed. Have to resize the pics and will post them soon...

Will post a lot more pictures soon...;)

WHAT???:eek: 1500-1600+HP???!!! That is unbelievable! AWESOME! Holy Moly... Do you know some details of this 1UZ? Stock crank and mains? Or billet and with girdle? 800HP out of 2000ccm isn't that new, but it's a lot stress for the engine. Do you know the boost level of your Buddy? But I've seen...

Haha...600 Maranello sounds very good! :) I wish you all the best for that "Italien (Stroker) Job" I'm sure, you will love it...

Wow John, that sounds awesome. A +600ccm is crazy! Is it a V12 engine? Darton is a good choice. I like them... We used sleeves for a Peugot disesel engine. They are cheap... My goal was to build a stronger block, not more displacement. ;)

Long block... First look at the (bad) short runner intake 90mm throttle body ...and (2JZ) ATI crank pulley...

The new 12mm ARP head stuts are a little bit shorter than the 10mm I got from David. So I had to machine the heads a little bit...
