Damn, 5 min of craigslist searching and I have already found a R154 for 400 bucks and a 2JZ-GE out of a 93 SC300 for 800 bucks.

If only I was back on the east coast right now......

The W58 will hold 400 hp 450 max and there is no need to go r154 unless you find a good deal. Witch it seems you did. You need to run a different bell housing I will check with my buddy to verify witch one. Also the clutch set up is a little weird but works great. I have another 2j sitting behind my house right now.lo, but it has no oil pan or wiring harness it ran fine when we pulled it out the other day to do a 1jzgte swap. If you look on craigslist or supra forums you can find complete 2jzge's for $600 with harness but $800 complete for a running motor is not bad at all. I along with almost everyone I know with a supra or 2j car is running a xs power ebay manifold they are $150 bucks and hold up great. I am also using a knock off hks 50mm waste gate. I would deff say go 50mm and not 40mm so you do not run into boost creep problems at high rpm and low boost.

If you want to wire your car up as a stand alone and run your stock starting and charging system let me know I know a guy that will do it for a decent price. He is the one that helped me with my harness. The fastest way by far is still Dr. Tweak and will be the best. Unless you do it yourself witch is what I did and it is not that bad.

I was planning on pulling out wires from a RX7 chassis to the point where I can still put a battery in the car and operate the wipers all lights and all that good stuff. If I get a 2JZ-GE, I would like to get it running NA using the appropriate OEM ECU. If I get the swap harness just Plug it in and go. anyother route and ill probly get lost! lol

I got this planned out really well in my head, I just cant explain what my thoughts on it are all that well.

I've worked on the SR20 (I've done about 4 SR20 swaps in to 240sx'), RB25, and RB26 (did a motor swap on a skyline, and also worked extensively on another skyline). The RB25 is definitely a waste of time. You're much better off to just get a sr20 and boost it up. They can easily make 300+ hp. The RB26 is a sweet motor, I love how the intake manifold is essentially a bunch of ITB's. The only problem with that motor is the cost and how freaking huge it is. Otherwise it's ****.

I just sent an email earlier today to the company that makes swap kits for the Datsun and Nissan community exspressing that there is interest in SR20 swap and that the only place actually making a swaps wants an arm and a dick for it. I just made a thread about it! If this can be done, ill be one of the first customers, if not the first!

No offence but thats pure american talk. Here in australia there are tens of thousands of both. The head design is almost identical with only a slight capacity decrease and no crank girdle. The rb25 oil pump cannot be run at over 7500 rpm reliably. and the stock computer has a low 14 psi boost cut.

I just finished a customers car (an rb25/30) with a stock rb30 bottom end that just made 470rwhp on 18psi wth a gt3076r. Nothing wrong with that.
Also why a 1j instead of a 2j? seems stupid.

Agreed with the above post.


I'm a pretty big fan of the Mazda engines. The idea of a 1j,2j,rb25,rb26 swap seems extremely generic to me. It's nothing new and will not be cheap. The power made will not be extraordinary at all, especially compared to some of the nut jobs on here that are shooting for 600whp+

If I had to consider a engine change it would be a fe-3 or klze(seeing as they are capable of running low 11's N/A in a 323 and sound godlike)

As an aussie, i love hearing americans talk about japanese stuff, we have heaps of sr20s rb's 2j's CA's etc etc etc. R33s everywhere. And when I hear Yanks talk about them its clear you guys just dont tend to have the experience.

Once again I agree. I guess it is just the appeal of running a motor that is not common.

But to each their own. No shame is running what you want.
