Rb26dett swap
 

i know I'm gonna get flamed,and ive searched but does anyone know of anyone who makes a prefabbed mount kit?or any ideas to go about sourcing one.I dont care to hear about not doing it or whatever else .I'd just like to find out where I can find one

You are talking about sticking a Nissan engine into a Mazda. Its like saying you want prefabbed mounts so you can stick an LS1 into a Mustang. Nothing is prefabbed so just make them yourself or get a shop to make some for you. This is something that requires alot of thought and planning before even trying to stick the engine in.

Yeah I don't think you'll find anything pre-fabbed for that swap, I've only seen it done a handful of times. Maybe work something out with one of the companies putting out V8 kits?

dude what rock do you live under,they make swap kits to put ls1s into mustangs.Also about 5-6 prefabbed kits for fcs....You should do some research before you say something you know nothing about

A 1jz or 2jz would be a better choice if you want a I6 turbo. You realize that the rb26 is inferior correct?

Tech2 makes a swap kit for the jz motors.

Yah i saw tech2's set up,haha ive just got a hardon for the rb26 for some reason.The 1jz is my next choice but i dont know i just want the rb26.

i have a rb25 in my fd. It was a huge pain in the ass to do everything. Although it was worth it in the end I would strongly reccomend going with the 2jz and the tech 2 kit. It sucks because the exhaust is on the wrong side on the nissan motors for this swap. Good luck on whatever you decide.

Yah thats what I was wondering,well thanks for the heads up.

jz > rb

Opinions are like assholes man,everyone has got one.

It's not a opinion.

JZ engines cost less, make more power and are more reliable. There is more information available on them, replacement parts are easily available, there are parts to make it a nearly bolt in, plug and play swap.


rb engines cost more and are harder to get. They are proven to make less power and be less reliable on stock internals. Not to mention there are no parts available state side.

If you want an I6, the logical engine is the JZ motor. A rb26 would be for the "hype" and nothing else.

That is unless you already have the full swap lying around. Then my all means go for it. But a JZ swap would be better in every category and that's fact.

fact is theres never a mass production car sold legally in the US with the RB engine
you are in trouble if u blow a couple bearings

good luck

I could not disagree with this post more. 2JZ motorsets and RB motors sets cost roughly the same. RB not reliable on stock internals? people take this to 500+ on stock internals all the time. (its called tuning) 2JZ motor isnt hype?

And i know of plenty of places that either stock RB parts or could get them within a few days.

2JZ is also a more difficult engine to fit than an RB.

how about them apples :D

+1

They are all good motors. Stop hating and let people do what they wanna do. Im sure they dont make mounts for RB to RX. Just custom fab it. But also you know you will need a custom driveshaft, standalone, you cant use the RB26 trans because its a AWD trans and you need the RB25 trans and ect...It all adds up to the point that you should have just stayed rotary.

People make 1000hp on stock 2jz. All business!

You can get 2jz parts at a toyota dealership, online or even at an auto part retailer like autozone or whatever.

You can't deny that 2jz parts are cheaper and easier to get. We also have the strong and cheap r154 5 speed easily and cheaply available.

They make more power for less money... indisputable.

Show me a complete rb26 motor (ecu harness etc) set under 1900!

JZ > RB ... always!

Anyways, I realize this logic could be applied to the concept of even using a I6 over a v8 at all. After all a LS1 is probably a better swap (lighter, bigger, etc)

It does just come down to a matter of personal preference. If you are really set on doing the rb26 swap... go for it! But if you want to pick the best I6 regardless of brand etc. , I would recommend you go with a JZ swap.


Anyways good luck.

If you really want that RB26... you're going to have to invest heavily into the oiling system.

The RB's oiling system is very weak.... which is counter productive to a motor that can rev to 8k

You are correct you can go to the dealership and get 2jz parts, typically of which are not in stock and have to be ordered which will take 2 days to a week (i work at a dealership i know)

2JZ motors DO make more power easier, HOWEVER, 2JZ motorsets are not as cheap as you make it sound, if your picking up 2JZ's for 1900 (im guessing motor ecu harness only, no tranny) i would hate to see them.

I have done a 2JZ swap before, the motorset W/ R154 tranny cost me nearly 3k. In which i can get a RB25/6 motor set WITH tranny for that price also.

Anywho, its a pissing match, I like both motors, but your blinded i believe by the fact you think the 2JZ is the cure all for power. To be honest in the short time i had my 2JZ i hated it.

Thats right i said it. Good power, piece of shit to work on.

When I did the swap on my mkiv, I got the R154 for $300 and the swap for $2200... it was all in great condition and runs great till this day.

You have to shop around to get the best deal (obviously)

When I did valve steam seals on it they had the parts in stock at my local dealer. Maybe it's different in South Dakota?

I've always found the 2jz a pleasure to work on, then again I never even ran the stock turbos lol

There is a difference between working a a 2JZ in a supra and one in a rx7 or 240. (note that)

Im not a big far of "shopping around" typically because your cheapest bidder (if you will) is typically just some schmo company trying to make money on motors they no nothing about or the condition of them. So i always buy from reputable companies.

as far as the tranny goes i believe i paid 800 bucks, plus i had to buy a shifter extension as the stock one sits to far forward. (im guessing the same issue would arise on a rx7) Which is typically a $125 piece by itself.

As far as you valve stem seals they very well can also cross reference from other motors (same valve size ect.) therefore it would typically be in stock. (and yes being in south dakota does make a difference obviously as we dont have alot of supras running around here) And your in cali chances are SOMEBODY i going to have a part you need within a day of driving. (or delivering.) OP is from Oklahoma, chances are they dont have many there either.

just noticed this part, chances are if your not running stock turbos anymore than chances are your not running the factory vacuum mess up on top (atleast i wouldnt) That is alot of the pain, plus the twin setup is a PITA to work around. So yes, in your case it simplifies alot. lol

^ I made my shifter extension with about $10 worth of metal :O

I got my engine from a local importer that i've purchased over 20 engines and transmissions from (i fix up cars on a regular basis) and it was super clean :D In fact I've never had an issue with anything I bought from them!

They do compression, leak-down and oil pressure checks on every engine they sell, with a 6 mo warranty

this is all from attarco in sacramento BTW

They are also practically throwing distance from me... and they know me by first name :D
This might have been a factor in the deals i got.... :)

Just remember cash talks and it helps to know people :D

Not everyone is stones throw from a engine distributor so shipping is a huge issue for 75% of people buying.

Yes shifter extensions can be made cheap, how nice did it look?

Listen to the smart people.

JZ > RB.

Only reason i am building the RB is because i don't want to waste my time with a swap, and i like the challenge.

let's just say not everyone has a couple years of fab experience and a nice TIG at home too :D

It looks great....

But I wouldn't care. You don't see it when driving the car or even under the hood.

:D
