msmile Posted August 20, 2014 Author Share Posted August 20, 2014 Nice find mate. Was that from the 1UZ Facebook group, forum, or website? Ebay... Quote Link to comment Share on other sites More sharing options...
Si_s Supe Posted August 22, 2014 Share Posted August 22, 2014 Subscribed!! I often think about doing this in the future. Had a TT which I sold to buy a house. Now I have an NA which I planned on selling to buy a TT (don't see the point in NA-TT when you can buy original) but my shell I so nice, would be great to have a V8. And that noise!!

j_jza80 Posted August 23, 2014 Share Posted August 23, 2014 Will be filling that gap with LS engines very shortly ;-) That's already done in the states, but LS engines are expensive. Either Uz or Jaguar Aj engines are cheap, plentiful and light. The supercharged AJs can make some serious power too. Quote Link to comment Share on other sites More sharing options...

Check this link, you can get 600hp from natually aspirated toyota v8, so I would say N/As always give you more fun that forced induction engines. http://www.v-eight.com/multimedia/pdf/600hp%20Naturally%20Aspirated%20V8%20Toyota%20Supra%20JZA80%20Hi%20Res.pdf Edited August 23, 2014 by msmile (see edit history) Quote Link to comment Share on other sites More sharing options...

I know nothing about tuning V* engines, so the above is a question, not a statement Seems to be a huge amount of work, for (what I guess is) quite a lot of money, for (in the grand scheme of things) not a lot of gain, compared to turbo'ing or supercharging.

msmile Posted August 23, 2014 Author Share Posted August 23, 2014 To get 400bhp is from N/A 1uz is cheaper than to get 400bhp from 2jz-gte (if counting the conversion price together), but If you want 500+ bhp - go for 2jz-gte. Cheapest and easiest way to get the horses but you must be sick in some way if 400 is not enough Quote Link to comment Share on other sites More sharing options...
Guest Raven Posted August 25, 2014 Share Posted August 25, 2014 Interested to know how you are planning to get 400bhp out of an Na 1uzfe, also have you removed all the cats in your conversion? would be great to see a dynograph of a derestricted VVTI 1uz you never know could be not far off 400 as it is Quote Link to comment Share on other sites More sharing options...

msmile Posted August 31, 2014 Author Share Posted August 31, 2014 (edited) ok, after some break things are getting there. Still waiting for the bloody engine mounts, which are under customs inspection for 10 days already!!! Meanwhile few more things sorted, and heres the first start Cant get enough fuel pressure for some reason...

straightsix Posted August 31, 2014 Share Posted August 31, 2014 you never know could be not far off 400 as it is Seeing as a 4.3 VVTi 3UZ is only just 300, I doubt it. Quote Link to comment Share on other sites More sharing options...
straightsix Posted August 31, 2014 Share Posted August 31, 2014 Have you bridged the fuel pump to run it at full 12 volt? Quote Link to comment Share on other sites More sharing options...
msmile Posted August 31, 2014 Author Share Posted August 31, 2014 Have you bridged the fuel pump to run it at full 12 volt? no, it runs Lexus setup with relay switching between resistor and 12volts, but that shouldnt be a problem as it is a stock setup.

straightsix Posted August 31, 2014 Share Posted August 31, 2014 no, it runs Lexus setup with relay switching between resistor and 12volts, but that shouldnt be a problem as it is a stock setup. So because it's stock, it couldn't possibly be a problem? And it must be operating correctly if you don't see the need to check anything? Just trying to help get to the bottom of your low fuel pressure..... Quote Link to comment Share on other sites More sharing options...

msmile Posted September 3, 2014 Author Share Posted September 3, 2014 I just binned three of these while clearing out the shed - didn't think I'd get any call for V8 spares thats the aftermarket one. Fuel rail is different on vvti and non vvti engines, so the vvti needs aftermarket FPC to fit Supra. Quote Link to comment Share on other sites More sharing options...
Guest Kunny Posted September 4, 2014 Share Posted September 4, 2014 Hello. Awesome project. That V8 sounds incredibly sexy. But sorry to barge into your topic. I'm also doing a V8 swap. Only my v8 still on the ground unfortunately. Anyway I am very curious on how your going to run your stock tach (that is if your using the stock tach). Are you going to modify you tach or just using a converter/adaptor? Thanks Quote Link to comment Share on other sites More sharing options...
Matty_L Posted September 4, 2014 Share Posted September 4, 2014 (edited) subscribed. I'm about to swap my soarer 1uz for a 3uz You had any thoughts on the rev counter? My non VVTI works on the stock gauge with MR2 guts in it, but that won't work when I go to the VVTI 3UZ Edited September 4, 2014 by Matty_L (see edit history) Quote Link to comment Share on other sites More sharing options...

My non VVTI works on the stock gauge with MR2 guts in it, but that won't work when I go to the VVTI 3UZ Sorry to jump in but the 3UZ picks up tacho signal feed from pin 16 on the ECU - plug E5 (Black/yellow tracer). I'd have thought it should wire up the same to the tacho input on the cluster. I know it's not relevant to your build msmile, but hope you don't mind as it's all V8 relative!

Maybe I'm misinterpreting what you said here but does this means the vvti still sends 4 pulse? I thought the vvti engines sends out a 8 pulse tach signal. I have I think a Celica tach somewhere and Techstream. Ill try this out tomorrow if the weather allows. Thanks for the heads up. Quote Link to comment Share on other sites More sharing options...

Any info regarding tacho conversion helps as this is the only point still in doubt. I do really want to use stock tacho (with or without mr2 guts) and have few ideas how to do that but nothing certain yet. Kenny - Celica mk1 tacho can be switched between any input, but 1.its really hard to find it breaking 2.not sure the tacho will fit Supra dash Let us know how it goes! I will try to use tacho signal switch from some aftermarket tachos. Edited September 6, 2014 by msmile (see edit history) Quote Link to comment Share on other sites More sharing options...
straightsix Posted September 6, 2014 Share Posted September 6, 2014 I disassembled a celica tacho and used that - I've got it in my head that it came from an ST182 model If you bend the four metal tabs out (the ones that hold the circuit board on) you can pull the circuit board from the needle mount assembly. Replace with the celica circuit board and re-drill the holes ever so slightly on the Supra cluster housing so the screws will go in and still contact the floppy circuit board on the back of the cluster. If that makes sense....... Quote Link to comment Share on other sites More sharing options...

Krister Posted September 9, 2014 Share Posted September 9, 2014 Check the link above mate, there are detailed writeups how you get 420 and 600 bhp out of 1uz N/A. I will surely try dyno after I finish with full decat. Can you link to the 420bhp writeup? Could only see the one with 600bhp. 420bhp is over 100hp / litre and stock are under 300bhp? I cant see how that is possible naturally aspirated without head work, cams, ecu etc.. Quote Link to comment Share on other sites More sharing options...
