91_4x4runner Posted June 22, 2007 Author Share Posted June 22, 2007 I don't think it's going to be too much of a problem with the springs. The 1UZ is a relatively light motor (aluminum alloy, plus only running an alt. on it). Even if it is a screwup and ends up being a waste of money, I'm not too downhearted about it. Live and learn (I'll just keep a positive attitude about it). I've decided that I want to get in on the Sportmax 002 group buy before it runs out. I'm going to get gunmetal grey (car will be painted a silver color). Then I'm going to try out these tires: General Exclaim UHP 225/50ZR16 93W They're quite a deal (80 bucks a pop on tirerack.com) and have great reviews. I'm really looking for a cheap summer tire that has good traction. They seem to fit the bill. If someone has a better suggestion of tire to go with (sub 140 per tire), please let me know.

Clifton Posted June 22, 2007 Share Posted June 22, 2007 The R154 won't have a problem with a n/a 1uz or even a lightly boosted one. People do break the thrust washers but you have to beat on them hard with alot of power. I would put the trans you want in it now. If you put the auto in now and later swap it later it will cost more. You might have to redo the trans mount and the exhaust and deffinatly the driveshaft. Here's a bunch of 1uz link http://1uzfe.com/hp_links.htm Quote Link to comment Share on other sites More sharing options...
91_4x4runner Posted June 22, 2007 Author Share Posted June 22, 2007 Yeah, I'm looking at custom exhaust (2x probably, turbo'ing it later), custom driveshaft at least once, fixing the trans. computer to accept a standard trans., bellhousing and other trans. costs. There is very little aftermarket for this motor, but that's what makes it unique. The more I think about it, the more I know I should do it right the first time. My original plan was to get it on the road ASAP and do the mods I want as I go, but that doesn't look like the most money efficient way to do it.

91_4x4runner Posted June 22, 2007 Author Share Posted June 22, 2007 Since the UZ blocks all share the same exhaust flange, I could go with SSAutochrome tundra headers ($175/set) while I leave it NA (quite some time... FI is over 5 years and countless lessons away). I've got to do more research on the different transmission options now, so I'll get back to y'all later on that one.

Wedge Posted June 22, 2007 Share Posted June 22, 2007 I was under the impression that the R154 could handle over 1K horsepower. Guess I was wrong. I'm a regular at lextreme.com as well as HybridZ. R154 is rated around 500hp most them break because of week a thrust washers in the tranny like clifton said it can be fix by chryo"ing" it . But i was saying go with tremec because Thorracing sells a kit with all you need to hook up the TKO man. 5 speed to it its nearly bullet proof .

Clifton Posted June 22, 2007 Share Posted June 22, 2007 It's not the HP that breaks things. It's the torque. If you can get a better trans for less I would do it. If you are going to keep it under 600 rwtq and not drag race every weekend an r154 would survive. Quote Link to comment Share on other sites More sharing options...
91_4x4runner Posted June 23, 2007 Author Share Posted June 23, 2007 I've been looking around for a cheap Tremec transmission since yesterday. I found one about 5 hours from me for 500 bucks obo (Tremec T56). I don't know much about these transmissions, except for the fact that they've been used in many high power applications. Only problem I see with them is most of them have incredibly low 6th gear (0.62 or 0.5), which would be nearly unusable at highway speeds.... Even if I was going for top speed, I don't think my little V8 would be able to push it. Not really a big deal, the 6th gear would be nice to have for the flat plains of west Texas. EDIT: Found quite a few TKO-500's near me, sub-500 bucks (Ford version). Can someone give me an idea of a decent price for one? Quote Link to comment Share on other sites More sharing options...
Clifton Posted June 23, 2007 Share Posted June 23, 2007 They are double over drive. 6th gear would ony really be good for cruise. A 4 liter engine should be fine with that in such a light car. You would definatly get good mileage on a road trip. Quote Link to comment Share on other sites More sharing options...

It has to be a Chevy one to work with the 1UZFE or the the input shaft wont be of the right dimension . Quote Link to comment Share on other sites More sharing options...
91_4x4runner Posted November 22, 2007 Author Share Posted November 22, 2007 Small and pitiful update: After about 6 months and 5 real hours of labor, I pulled the engine, computer, and harness (uncut). I ordered a complete top end rebuild kit with pretty much every gasket and seal available. (325 bucks) I should start disassembling and swapping stuff out this coming weekend if I can come up with some time. From there, it's time to wheel out the Lexus donor and wheel in the Z. Moving along slowly... Quote Link to comment Share on other sites More sharing options...
ROVdriver Posted December 5, 2007 Share Posted December 5, 2007 Have you bought the SSAutochrome headers for your UZ? I'm doing the same swap in my Z, but I can't decide if i'm gonna do FI or NA/with itb's. Quote Link to comment Share on other sites More sharing options...
91_4x4runner Posted December 6, 2007 Author Share Posted December 6, 2007 I haven't bought them yet as I have just begun my engine rebuild. Also, I started talking with a friend of mine the other evening and he has started a plan on building his own car (80's camaro). It looks like it is going to be a horsepower shootout between the two of us. The only way I can beat him is FI. For the time being, I am going to use the stock exhaust manifolds with side exits (uses less pipe). I settled on the T-56 transmission for the double overdrive and as I doubt I could make enough power to break one. (If anyone has one for sale in TX, let me know). Some folks at Lextreme are having a custom bellhousing/flywheel/clutch kit made. Here's some initial teardown pics: http://img.photobucket.com/albums/v235/trainman235/1UZ/IMG_1211.jpg http://img.photobucket.com/albums/v235/trainman235/1UZ/IMG_1218.jpg http://img.photobucket.com/albums/v235/trainman235/1UZ/IMG_1225.jpg http://img.photobucket.com/albums/v235/trainman235/1UZ/IMG_1226.jpg http://img.photobucket.com/albums/v235/trainman235/1UZ/IMG_1236.jpg http://img.photobucket.com/albums/v235/trainman235/1UZ/IMG_1243.jpg Quote Link to comment Share on other sites More sharing options...

91_4x4runner Posted December 6, 2007 Author Share Posted December 6, 2007 I left them off initially..... It's not a big deal either way. Click a link or make the poor dial-up folks wait ages. Quote Link to comment Share on other sites More sharing options...
Pete84 Posted December 6, 2007 Share Posted December 6, 2007 Is that the complete wiring harness? Quote Link to comment Share on other sites More sharing options...
91_4x4runner Posted December 8, 2007 Author Share Posted December 8, 2007 That's the complete harness from the engine to the ECU/internal harness. It doesn't include the wires that go to the instrument cluster and whatnot. I've got to fish out the fuse block and whatnot today after work.

91_4x4runner Posted December 8, 2007 Author Share Posted December 8, 2007 Sometime around Christmas I plan on buying new rims (and I've got credit for tires). I'm only going to be putting about 200hp to the wheels at first, but I don't want to upgrade to wider rims when I start putting more power down (won't be going over 500hp, ever). I'd like recommendations for rim/tire size. My current idea is 16x7 (0 offset) and 225 55 16's. Ideally, I'd like to find the compromise between low drag and ability to put power to the ground.

Clifton Posted December 8, 2007 Share Posted December 8, 2007 I wouldn't worry about low drag, it's an S30 not a Honda insight:mrgreen:. Having a narrow (streetable) tire and getting power down doesn't happen, I'm sure others on here with big power will agree with that. If you are planning 500 hp with a turbo, your torque will be high and there will be more of a traction problem than a 500 hp n/a motor. Go as wide as you can and hopefully you can use a street compound. Quote Link to comment Share on other sites More sharing options...
91_4x4runner Posted December 8, 2007 Author Share Posted December 8, 2007 I completely agree with you that a narrow tire won't get alot of power to the ground. Lets say though that I keep the stock setup for a year or two, do I really need a huge set of tires? I think not. I figure that I'll put 35K miles on between the initial setup and the turbo'd setup, so that's one set of tires down (depending on tread life). So for my stock 1UZ (generous guess, 200hp to the wheels), do you think that 225 55 16's will suffice? That's roughly 25.7" tall and 8.9" wide.

Clifton Posted December 8, 2007 Share Posted December 8, 2007 It's the torque that's the problem. A stock 1U shouldn't make too much to the wheels. Tread wear is a good indication of traction. A tread wear rating of 340 won't be nearly as soft as a tire with a TW or 180, the lower the number the better it will stick but the less tire mileage. If your stock for now I would run what you have. Quote Link to comment Share on other sites More sharing options...
