I wonder if Crower would let you specify crank and rod dimensions. Specifically, things like the rod diameters and such. I think the best thing to do would be to get a 4.3 block (since these engines are pretty cheap anyway) and offset grind the crank to the SBC spec. Use an SBC rod with a...

It would be nice to buy an engine to modify and not have to even machine the bottom end at all.

That sounds about right. I am looking at using 950cc injectors for headroom of 600 hp for my 4-cylinder. High impedance injectors are usually easily swapped for low impedance. Does the 1UZ use a resistor pack for the high impedance injectors? If so, it should be as easy as taking that out...

This is a great thread, you're a fast worker!

The T56 is a bit large for the chassis I'd like to put the engine in. Is there any good reason to choose a TKO over a G-Force T5? Has anyone ever used a G-Force T5? I would be using their dog box. They say that they aren't only good for 600 hp but that seems surprisingly low.

For the guys building big horsepower turbo/supercharger setups, what manual transmissions are you looking at? The Getrag V160 seems to be the best option, but are kind of pricey and require modification of the bellhousing. A built T-5 also seems like a good option, but they are only rated to...

Well, I understand it would wear out. But honing versus boring is a good deal easier when the engine is so durable.

With the 4g63 and DSMLink, I've seen 850's idle perfectly. DSMLink allows you to adjust the global fuel settings and dead time of the injectors from stock. The PowerFC does this too. I haven't really played around with any other EMS's. Basing it off the stock injectors seems to make it a lot...

That's pretty amazing. So what that means is, as long as there's no catastrophic engine failure, such as putting a hole through a piston or breaking the ring lands, that the motor shouldn't ever need to be bored over?

Well, sorry to say, I'll have to get the engine first. But I'll definitely be a pioneer for oversized valves if I must. One question though. Seeing as how the 2JZ engine was designed for "performance," can anyone tell me why it's exhaust valves are 1mm closer to the size of it's intake...

Based off my 2.0L DOHC turbo 4-cylinder, I would say at least 800 horsepower.

Well, I just checked out the site and I must say it was pretty cool. By far the best part of the site is the videos. The sound of the exhaust is what I expected; well-muffled by the turbo, with lots of turbine wheel noise. The problem is, for me, I don't like the sound of some of the v8's...

I would imagine, seeing how real intercoolers have fins and turbulators to transfer heat, that the heat loss of hot compressed air through piping would be fairly small. I just don't see how lengthening the piping could cool the air enough. I mean, some cars already have that much piping, AND...

Nice car! I kind of like the stock car look better than the yellow one, but hey, it's your car. It'll be nice seeing the 1UZ there when you pop the hood. :)

I think I'd be willing to try 1mm over using the stock seats. I'd rather get lighter, swirl-polished and nitrided valves anyway, and since oversize valves are common (and using the stock seats wouldn't require much work), I figure why not. What about naturally aspirated? I realize that...

I realize that; however, I don't have the fortune of having a 1UZ head to look at. I've heard of shops machining the stock seats on other engines, any particular reason why you don't think it would work? I hope I am not coming off sounding arrogant, I am honestly just searching for...

Trying to find where to mount two turbos on a 1UZ RX-7... and then I read this thread... hmmm... I would say that I also do not like the idea of a rear-mount turbo. Not only do you have much more exhaust pipe before the turbo, but you also have a lot more intake pipe after. But I know some...

Looks like the 60-ft's need to be switched. 1.8 and you ran a 16? Seriously? I don't see how that is. But nice job, 1.8 60-ft is pretty good.

To dig this thread up, I've seen the video of the induction setup, and it sounds great. But I was wondering if someone could make a video of what the exhaust sounds like. I imagine these would make it much more aggressive.

If we are using Supra valves and valve springs, then logic dictates we'd be able to use the Supra retainers too... Titanium retainers... drool...
