rb26....... not too sure about the bottom end 2jz's are tested and true when i put this much money in a car i dont want to be unsure about anythin

 

You know the I-6 RB26s are tuned to 1000+ hp time and time again as well. there is a RB drift car 350z. perhaps someone could chime in on the disadvantages of going one way or another?

From what Ive read so far, the 2JZ is preferred because of the strong stock bottom end and produces more torque due to the .4L difference, but with a built RB26DETT it revs higher and has similar power outputs especially if you do a long stroke build to RB30DETT, it's pretty much identical to the 2JZ.

It comes down to how much you are willing to spend, also the turbo placement on the 2JZ is on the side, so the Twins won't fit in our engine bay, where the turbos are bottom mounted on the RB and MAYBE could clear the steering rack, then in this case it'd make more power with a RB than a 2JZ with single turbo.

 

I'd go all aluminum LS3 but anyhoo.

In regards to the stock twins on the 2JZ, no one keeps those if you want over 400hp or so. So no problems with turbo placement as everyone goes single anyway

 

With the swap it has to be a single turbo. Can't use twins - no room.

no offense to the op, but ur in way over ur head. go to a shop that has experience with wiring, and ask how much they will do it for.

 

Properly built Vq's that are stroked and boosted have hit 1800 hp. You would spend more putting in a 2jz and tuning it to 1000+ hp than you would just building boosting the VQ. You would have a lot more tq with the VQ too.

 

wonderfull thats where all our money is going.

cant wait until we figure out an alternative fuel. so they can stop raping us.

 

vq with more tq than an I 6 cmon you gotta be kidding if you show me were there is a 1800 hp vq i will personally stop calling these guys and start ordering parts for the vq i alredy found a guy that wants to sell me a 2jz stock with twins for 2000 usd no trans yet but the motor has like 156000 km on it

 

witch do you think would be more reliable some

 

how much HP are you aiming at.
basically, between 300 to 500hp you can run the 2jz with little to no modifications to stock internals, when you are going to 1000hp the amount of money you going to spend is the same as an RB and potentially a RB will be more daily driving friendly at 1000hp than 2JZ single turbo at 1000hp.

personally with such similar specs, i'd rather put a Nissan engine in a Nissan. call me weird but that'd be more impressive than putting a Toyota engine in a Nissan despite it's the best Toyota engine. It would almost be like once you cross the brand boundaries people will start asking...oh why didnt you just put a big block in it and call it a day, it makes the same hp with less money. you know what Im trying to say? on that note there is a Z with a corvette engine swap.

This is just one example. Of course the Vq's will produce more tq, they already have more displacement, and with a stroke and bore they will have even more displacement. Dont get me wrong, the 2jz is an awesome motor, and ive rode in a supra with 700whp and that thing is a monster, but these two motors cannot be compared. I also love the rb26's..i have one sitting in my garage. The Rb's and 2jz fully built net similar hp. These builds to get them to 1000+ hp can run you 40-50k, not counting the money it will cost you to custom swap the motor in. For less than the cost of building a 2jz or an RB you could have a VQ with more power and tq.

 

^cheaper if you go with GTM or Brian Crower and twin turbo if you want to go that route. Wongy's car had the Brian Crower 4.2 stroker with JWT TT and Haltech running daily driving at 600whp on pump gas.

 

well that was just one example...He used the example of a 2jz with 1300 hp. so basically fully build the motor and slap on twin 35rs or go with twin gt40's.

 

Wow that would be one sick project. I mean hell if the Wicked CAS guys can drop a Vette Motor into a 350Z then I dont see why this swap cant get done.
