I know this sounds like a stupid question but is that really how these water-to-air intercoolers work for a roots styles supercharger. I know the water is plumbed through the intercooler and then to a heat exchange located somewhere else to cool the water after it was made hot by the air...

Lextreme, What type of Roots style intercooler are you looking at? Do you have any links or pictures of what you are thinking about? I ask because I was considering doing a roots style supercharger but didn't like the fact that the intercooler options were limited. I liked Jordy's setup...

Here is a question for you guys. It is not necessarily related to any specific Lexus model but since my race car has a 1UZ I figured I would ask it here. What is the proper design for a vented or non-vented gas tank? Like how much pressure or vacuum should be present? Should it be designed kind...

Kiwi, Here is the US it is the exact opposite as you describe. We can get small block chevy's for extremely cheap. (We can buy 1UZ's for cheap too but the Chevy's are even cheaper.) You can build a monster Chevy for much cheaper then you can a 1UZ here is the USA. I guess that is because...

Well at first I was going to turbo or supercharge teh engine. Then I decided lets just keep the car the way it is because it is already insanely fast and if I increase the power too much then I would start to break things more often then I already do as it is a race car and not a production...

yeah its a race car of some sort. Actually its a street version of a Saker SVS. It is light enough with a mid engine that you don't need/want power steering or brakes. But what are the vacuum lines for that I currently have on my car? Aren't they used by the ecu as ONE OF THE MANY parameters...

What would that be without the ITB's? Just curious as I am looking at getting a set of those but don't know if I want to spend the money on the hp increase.

Wll I don't have power brakes or power steering so do I even need a vacuum tank? I have a couple of lines that run from the manifold to other parts of the car. Like I have a really small tube that when unplugged makes the car run very rich, so I'm assuming this is the vacuum line that tells...

Well this discussion has of course sidelined into the chevy vs lexus thread, but that was expected. At least no one has started an arguing match. But there is no doubt that the lexus engine is built better then the Chevy engines, which is why they are more reliable. But I honestly don’t think...

Looking for 500hp at the crank. Of course if you can make one that will give me that at the wheels I wouldn't so no butr I don't see that happening in reality. Would you guys be willing to build an extra engine strictly for sale? I am wililng to buy.

Ok, Does anyone know of a place that will build a high performance 1UZ for me? Or does anyone with experience want to take on this challenge for me? I’m looking at buying a 500hp (475-550hp is my range) and wanted to know if anyone knew where I could get such an item. Toysport.com seems to...

I was talking with Tony Milla at 1uzquadcam.co.nz about his 8 throttle body setup for the 1UZ. He said the fuel rails can be used but must be reversed and that the lugs need to be re-welded for this to fit. Probably not to bad but definitely not a bolt on item. He also said that a central...

Well I have a LINK ECU in my car so the tuning should not be a problem. I am planning on getting it retuned here shortly so then I will have an exact idea of what type of power I'm making exactly. Here is a spec sheet of my cams. I don't know much about this topic so if you could tell me if...

Peewee, the hp/l figure is impressive as you state. Thats why I like the Subaru STi as it makes 300hp with only 2.2L 4 cylinder (I think that is the right size). Of course it is turboed but that is still very good for a production car. But I still wouldn't buy one even though it is very...

wow, that was actually the best reply one could give. Know I see that over head cams are a better design then pushrods as I always knew they were. Although you have a point of the less mass in the OHC engines as opposed to the pushrods, I don't really always see the reality of the advatanges...

I have a question for you guys. To put it plainly, why are Overhead cams better then push rods. I'm sure they are better but exactly why is that the case. I mean everyone knocks the Chevy V8 for being old school technology because of the pushrods but then again how long ago were over head...

Hey, I have a question concerning cam timing. I have an engine with a modified cam. After I received the engine the engine builder said that more power can be gotten if a degree cam timing change was made. He gave me a spec sheet of what I need to set it to in order to get the power...

Hey, My engine is leaking oil from somewhere at the top front, right side of the engine. When I take the black plastic cover for the cam timing belt off there is oil inside there. It is NOT on the belt, gear holding the belt, or distributor but it is further back closer to teh valve covers. I...

Thanks guys, I think PeeWee and Zuffen are hitting this on the head. The car is running way to rich so I need to reprogram the ECU to run leaner. I am already in the works of adding a fuel cooler to the system, more heat shielding to the fuel lines (even though they aren't really near any heat...

OK, I am having a problem with my 1UZ-FE in my Saker SVS and I can't figure out what it is. Lets see if you guys can help me figure it out. My car seems to "run out of gas" after driving it for a while. I trailered my car to the drag strip with a full tank of gas. I drove it out to tech...
