You will need a big budget and couple of snails at least 16-20k. Money will go out very fast.... Currently i am collecting parts for my Project Lextreme.

yea i bet....i guess i will just try to find a motor off ebay or somthing. or i will try to find a really smashed tundra and get the motor out of it. i like this idea better...oh snap i can get a motor from a jappanesse import place for like 1200 ill check it out on monday...does any body know what year i should get it from...im thinkin like 2000-2003. probably going to have to do some major fabbing to get that big sucker to fit in my car...wonder what the horsepower is on that motor..

yea it does sound awesome...that sounds like raw horsepower...i can't belive thats a lexus motor tho....thats crazy...well maybe for now i will just use the tundra bottom end with my heads on it and a 98 sc400 intake manifold...that should give me some sorta power i hope...i got my true dual exaust yesterday with magnaflows and it sounds awesome its quiet at idle but when i step on the gas it sounds sick...

By the time we're done, displacement is up between 454-468 ci. Which translates to close to 8 liters. That's double the dispacement than the 1UZ. With the Chevy, the engine is completely custom, which again is something we don't have the resources for with the 1UZ. Final figures on a Chevy SB at that size usually yields 700hp and 650-750 lb/tq. Again, this is all dependent upon cam selection, roller ratios, intake layout, etc.
Without somesort of FI on the 1UZ, there just isn't enough out there to build up a N/A motor to the specs you are mentioning, without some SERIOUS cash outlay.
And to answer your question, your 92 SC400 was rated at 250hp at the crank from the factory. It has now been pretty much agreed upon that that number was inflated and the output was probably a lot closer to 225 at the crank.

Sure! A stroked BBC can be pushed to 900+ HP. Car Craft does it fairly often and their last time it was N/A and ran on pump gas (93 Octane).
2.25 BAR on a BBC is tough. I'm sure it's done, it's just that I haven't seen one personally. Definately need to go custom heads for that route with some monster head bolts! Plus your compression would have to seriously LOW!!!!! Tolerances on American blocks and heads are just not as exact as their Japanese counterparts.

I researched the bore and Stroke #'s one time and it was so small of a stroke diff it would only account for about a .1 to .2 difference if I remember correctly.
How to build a High Output SC400 1UZFE motor :
Crank, polished and cut.
Longest Rod you can fit . Long stroke strong Rods work. ( Exe. 350 motor to 383 is big Diff )
Over bore pistons. Bores need to be honed as straight as possible.
Full head work, flow bench porting, enlarged Combustion chamber work. CC'd for even compression and size. Bigger Valves, HD springs and Valve train components that are ligthen.
Cams High lift , long Duration cams.
Enlarged Throttle body, and high flow exhaust system exhaust.
1UZFE built like this with street gas compression reving to 8000 RPM might be capable of 550 to 750 HP depending on Bore X Stroke and building skills. Many Chey 359 motors make this.

Woa, did you read the link. It's right there. I'm not the only one who thinks this. jgscott
Sorry what are you cutting on the crank to make it high hp?
You can lighten a crank, also do Knife edging, it's been done for years. jgscott
How much longer and where do u find them? Do u think the 350 rods would work?
There are Custom rods companies that make custom rods for anything you want.jgscott
Sounds nice on paper but have anyone done this? Is it proven?

I'm kinda confused about what you are saying. You should read A Book called "Smokey Yunicks Power Secrects". This will help you understand what I am saying. Everything you are asking about is right there and been done for years. IMO some of you guys who spent big bucks on turbo charging the 1UZFE got caught up in the Turbo thing and could have put together a higher HP, unbreakable V8 for the same money or less, without the Turbo Boost stress. Seams they keep rebuilding and rebuilding. I commend you for your project but, the things you are asking are not new V8 facts. Lots of questions so where are you going with this ?

Things you can do to a Crank for HP increases
:Inspection / Teardown
___ Blueprint (true, weld, balance)
___ Polish
___ Magnaflux
___ Straighten
___ Balance
___ Index
___ Oil Flow Modifications
___ Lighten
___ Knife Edging
___ Micro-Polish Journals
___ Radius Throws
And STROKE !
