Second Gen Posted June 13, 2011 Report Share Posted June 13, 2011 I have a 1993 Mazda RX7 and have been thinking about going piston.. Lots of people doing LSX swaps, but wondered about the Toyota/Lexus swap for a 2UZFE (4.7 in a couple SUV/trucks). Facts about the motor Seems to be mostly aluminum 270HP/340 Tq Want to autocross it again (Miss it) Opinions?? Know of anyone that has used this motor in anything else?

ImUrOBGYN Posted June 13, 2011 Report Share Posted June 13, 2011 I know they've been succesfully swapped into other applications and seem to do well, but honestly I dont know details. Would be interesting. I wonder what the size and weight diff is between the two v8's. Quote Link to comment Share on other sites More sharing options...
Second Gen Posted June 13, 2011 Author Report Share Posted June 13, 2011 Just found a build (Way more than I want to spend) on a guy doing one in a Supra. Nutty/crazy build.. Still reading it.. http://www.supraforums.com.au/forum/mkiv-discussion/23708-pics-my-4-7l-tt-build-up-mkiv-swap.html Quote Link to comment Share on other sites More sharing options...
Alex L. Posted June 13, 2011 Report Share Posted June 13, 2011 Don't base your build off bebop's, there's more than meets the eye in a bad way. Quote Link to comment Share on other sites More sharing options...
Squidward Posted June 13, 2011 Report Share Posted June 13, 2011 I know there are a bunch of 1uz and 2uz's being dropped into toyota trucks with a good amount of success. Quote Link to comment Share on other sites More sharing options...
Second Gen Posted June 13, 2011 Author Report Share Posted June 13, 2011 (edited) Both of you work @ the same place and completely different opinions. Got to love it.. Agreed on the Bebop's build. Was looking for a cost effective build and one that would be a good fit for autocrossing.. Since it is a truck motor it should be great for torque and being a toyota it should last a while (Did I mention I had a 2000 Tundra and own a 2006 now too). Both were/are the 4.7 2UZFE motors.

Alex L. Posted June 13, 2011 Report Share Posted June 13, 2011 If you haven't registered on Supraforums, do so and look through this: http://www.supraforums.com/forum/showthread.php?602477-New-SP-Project-Cowboy-Bebop-s-4.7L-TT-Supra-visits-for-some-quot-minor-quot-work They're good motors and would be awesome for what you want to do, but you'll see why I said to look away from bebop's. Everything Eric does isn't quite as it seems. Quote Link to comment Share on other sites More sharing options...
Second Gen Posted June 13, 2011 Author Report Share Posted June 13, 2011 Appreciate the clarification and was concerned it was a problem with the motor/drivetrain.. Your reply was about the quality of work (Or lack of) on the build listed above.. Thanks!!! Quote Link to comment Share on other sites More sharing options...
Nickey4271647545519 Posted June 13, 2011 Report Share Posted June 13, 2011 If you want to do something different. Why not do a nissan VK56DE swap. Came in the titan and a few others. Makes more power, and is also all aluminum. Quote Link to comment Share on other sites More sharing options...
carl1647545492 Posted June 14, 2011 Report Share Posted June 14, 2011 2 jz would be a cool swap ie its jdm! most of the motors sit high so the shape of the hood is a bit off I have a link on my other comp that i will post has some good info Quote Link to comment Share on other sites More sharing options...
Toyotahead Posted June 14, 2011 Report Share Posted June 14, 2011 2uz-fe is an iron block with alloy heads, weighs approximately 80 pounds more than its siblings the 1 and 3uz. They're excellent blocks if you're looking to make loads of horsepower, but if you're worried about maintaining balance I'd toss the crank into an early 1uz block and use appropriate rods and pistons to match. You'd still be a 4.7L, just without the added weight. Alternatively there are other options as well, the 1uz-fe without vvti is extremely tunable, cams, supercharger manifolds (using the ubiquitous Eaton M series), individual throttle body manifolds, and even Holley carb manifolds are available, and they're much easier to tune with an aftermarket ecu given the lack of vvt. Here's a great website with loads of information and discussion on the engine and tuning possibilities. www.v-eight.com Also check out this link for an idea of tuning the car if you go with a vvt based engine, 4.3L all alloy quad cam making silly power at 9300 rpm (short shifting no less, cams were designed for 10k+): http://www.v-eight.com/tech_forum/viewtopic.php?f=10&t=99 I would recommend heavy reading before diving into the swap, as parts can be somewhat problematic to find. I was thinking about doing it for a long time, but decided I didn't want to run a ton of power and I'm broke as a joke. I will say this: the engine itself is fantastic, but do not use the factory intake manifold, exhaust manifolds, or ECU. You'll be putting out a max of about 180 hp and 240 tq if you do, they're huge bottlenecks and they're wastes of time. A back to back dyno between equal 1uzs, the only difference being one had ITBs, showed a 75+ horsepower increase just by going ITB (185 vs 274 iirc). Both of those were W58 transmission Soarers with fully programmable ECUs and headers/exhaust. That's how terrible the factory manifold is. Mild cams will also give massive gains, a1turbos in New Zealand is currently putting down over 330 whp with what amounts to being a mild 256 or 264 grind in their rally Levin with ITBs. Some vids for you to enjoy haha: 13.x:1 compression, 288 cams, itbs w/ trumpets lengthened 100mm, w55 or w58 trans, headers/exhaust, and standalone. 370 whp iirc, may be a bit less. Ed's JZA80, 410 whp and 9300 rpm redline. He's now building a new block and dry sumping the engine to make more power and rev it to where it needs to be.

neonkiller Posted June 14, 2011 Report Share Posted June 14, 2011 Just buy a 600 truck lsx motor and be done with it, good heads and a cam +450hp... Last forever. Quote Link to comment Share on other sites More sharing options...
