spider2123 Posted July 31, 2012 Share Posted July 31, 2012 I'm thinking of going 1jzgte and was wondering how well the engine does in a supra compared to the 2jzgte? Anyone running 1jz auto? Quote Link to comment Share on other sites More sharing options...
welshbuddy Posted July 31, 2012 Share Posted July 31, 2012 I run a 1jz. As do little num and Pedro. They are a revvier engines the 1jz. Turbos are parallel on a 1jz, kick in at same time 2jz run 1st Turbo then 2nd Quote Link to comment Share on other sites More sharing options...
spider2123 Posted July 31, 2012 Author Share Posted July 31, 2012 What kind of 0-60 time you running? Is it a weight save? Quote Link to comment Share on other sites More sharing options...
Luxluc Posted July 31, 2012 Share Posted July 31, 2012 (edited) Littlenum was running 380bhp through his 1JZ. It was really fast. Edited July 31, 2012 by Luxluc (see edit history) Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted July 31, 2012 Share Posted July 31, 2012 Compared to a 2JZ the 1J is physically lighter, revs higher (but its not recommended to regularly hit the limiter without some bottom end attention), is a true twin turbo, almost as powerful in stock trim but has less torque (which helps the weaker W58 a little) and is just as strong/tuneable with almost as much in the line of tuning parts available. 1JZ head was also developed by Beams/Yamaha, I'm not sure if the same applies to the 2JZ They can also be picked up for considerably less than the 2J which means more money to get it all sorted. I'm very happy with mine, thankee sai. Quote Link to comment Share on other sites More sharing options...
spider2123 Posted July 31, 2012 Author Share Posted July 31, 2012 Sounds like more fun to be had with the 1jz and less hassle going manual (5speed). so a BPU'd 1jz would make....bhp? Quote Link to comment Share on other sites More sharing options...
welshbuddy Posted July 31, 2012 Share Posted July 31, 2012 Bout 380bhp. Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted July 31, 2012 Share Posted July 31, 2012 Sounds like more fun to be had with the 1jz and less hassle going manual (5speed). so a BPU'd 1jz would make....bhp? 380 - 400bhp at the flywheel without much fuss. I was dyno'd at 320bhp @ standard boost (0.7 Bar) and 6k rpm, couldn't take it any higher on the day than that due to me being a pleb and the petrol in the tank being 2 years old. I'll do another run in the next few weeks to get a better idea of it's full potential. The NA engine I had in the car prior to the swap produced 196bhp with a tubular manifold and a decat on the same dyno. Quote Link to comment Share on other sites More sharing options...
spider2123 Posted July 31, 2012 Author Share Posted July 31, 2012 Getting into an NA after not driving a supra for two year felt fast enough but it is wearing me down now, need to talk to Conrad and see of he's 1jz swap is still avalible . Standard power(320) would be a massive improvement. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted July 31, 2012 Share Posted July 31, 2012 I was getting 380 on stock fuelling and turbos on a 1JZ Soarer. Both engines have totally different characters when driven back to back, 1JZ is more free reving and responsive. They respond well to cams and a single turbo, nice Holsett HX35 would give you a proper quick car. Quote Link to comment Share on other sites More sharing options...
spider2123 Posted July 31, 2012 Author Share Posted July 31, 2012 Such a tempting swap, do I need to replace the diff on my NA to cope with the power? Does the soarer diff fit? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted July 31, 2012 Share Posted July 31, 2012 Soare diff is the same item as the J spec Supras, obviously geared different for autos and manual Quote Link to comment Share on other sites More sharing options...
