Decision time RB or 1J

[dillusion13]

okay guys, done my research but still torn between two choices.

Option 1:rb25det, greddy intake mani, greddy rspl intercooler, 3"downpipe and test pipe, 3" catback, and fuel pump.

Question.........how much do you think this would put to the wheels? If I change the turbo, to something slightly bigger, how much whp can the injectors take?

Option 2:1JZ-GTE, greddy rspl intercooler, 3"downpipe and test pipe, 3" catback, and fuel pump.

Question: how much whp do you think this will make?

I plan on changing injectors and computer at a later time, but for now, this is the only thing in my budget.

Any feedback would be appreciated.

with the rb thats a recipe for 250-270 at the wheels depends on what boost you running. on the 1jz you will get about the same but have spent less money. thats what im doing right now just sold my rb25 s14 so that i can build a 1jz s13 should be fun.

[dillusion13]

funny you mentioned that, thats the car its going into

[gani]

i have driven 1jz lexus and its pretty impressive so i cant wait to feel it in the s13 2400 pounds and 280hp stock you gotta love it.

[themadscientist]

Freind's R32; R33 RB25DET, SAFC, full exhuast, GT-R intercooler, boost up to 0.9bar and HKS 1.8mm steel head gasket 300+ HP on the dyno.1JZ is stronger in the long run but if I were going to do that I would just step up to the 2JZ

actually i know a couple of supra guys who put 1jz head on 2 jz bottom end and post better numbers.

[themadscientist]

called a 1.5JZ, very popular in Japan.

[dillusion13]

on the 2JZ, full exhaust and turned up boost.........350-400 rwhp attainable right?

[gani]

just about

[themadscientist]

yup. The J series engines are virtually bulletproof.

[gani]

i give props to nissan for producing badass 4 bangers but when it comes to inline 6 motors toyota owns. i had to learn the hard way by losing to a 2jz lexus.

[GrimDrifter]

check out http://WWW.GARAGEWORKSLTD.COM they have a 1jz s13. i cant decide on the motor either, but i really an a hardcore nissan guy, so i might just stick with the rb... http://WWW.japanesemotorsport.au <--- 600whp rb25 in r33. i dont know anything about the 1jz other than what cars they came in and that it is a TT 2.5l. i dont know which motor is stronger stock for stock. the rb25 doesnt seem to me to be a crazy monster motor..

[Project240]

1JZ S13??? WTF???

I know tuning shops do crazy inter-manufacturer engine swaps all the time, so it's probably not THAT big a deal, but is a 1JZ S13 a viable option for most of us enthusiasts who don't have full mechanics garages and bottomless bank accounts?

Gani, you said the 1JZ would net you about the same results as the RB25 but for less money. Are you talking about just the motor in general, or the motor swapped into a 240SX?? I just can't picture a swap like that being very cheap....

[rbsileighty]

I would say definitely go for it.

[l2andom]

is this swap anymore difficult than a rb swap? and how much more/less would it run you?

[rbsileighty]

It is only more difficult due to the lack of documentation. However, you could most likely use one of the guides from a RB install and try and make similarities between the two for the wiring (what is needed). Using a book for the 1JZ wiring, it should be fairly straight forward. Mounting would be a matter of having the motor and taking the time to make the mounts/adaptors). It would be a lot of fun, honestly. I'm sure it's far from easy, but it is far from being too difficult.

This would be a inexpensive swap for someone doing all of their own work.

i was considering the jz series for the J.

even though the 2JZ has more potential, i dont really like mutts.

and im dying to get some experience with the RB26's...

As you've noticed, I think it's a neat idea (thought about the JZ swap before), but I still picked up the RB20. Maybe if money and time allow later down the road. I think a 2JZ-GTE powered LS400 6spd would probably come first. Chances are I'll be playing with Nissan's for a while though.

[IvoryJ30t]

if i were to do a lex, it would be an early GS300 or SC300 with the 2JZ+6 speed.

thats an expensive endevour though. i got the J for pretty cheap, the early GS and SC's are owned by people who think they are worth their weight in gold.

after im done putting the J together, i might get rid of my Durango and pick up an S13 to play with.

[GrimDrifter]

ive seen 1jz motorsets for half of what the rb25 ones are, at least just on ebay. the cheapest 1j went for 1400, avg about 1800. im sure there are plenty of toyota sites with the wiring diagrams and whatnot. though im not sure about sticking in a toyota motor into a nissan, even if it is a better motor.

[IvoryJ30t]

i know the motors are cheap, but i would have to spend twice what i did for the j to pick up an sc or gs.

[gani]

well the motors are half the price of the rb25 and mounting it in a 240 is fairy easy then comes the wiring which i just get the 1jz wiring diagrams and for the 240 and try get some thing. or i can do it the easy way and just get a haltech...............

[RideFX]

I dont know why I havent heard much about these swaps but just recently the 1jz and 2jz swaps seem to be what every one is talking about. I think its an awsome idea seeing that the rb motors are becoming increasingly hard to source+ getting expensive. Any one interested in the 2jz swap cheak out this place...for once something sweet happening close to where I live I think if i wasnt in school I take out a loan right now to get this done!

I had seen that before, and always wondered how legitimate those guys really were. If you could stop buy and check them out, I am curious.

[Hexametaphosphate]

Alright.... assuming that you have a s13 or s14 w/o motor or transmission just sitting around would it be cheaper to get an RB25 or a 2JZ-GTE (or 1JZ-GTE) in a 240sx and running? I honestly have a little loyalty towards Toyota (my first car was Toyota... haven't had a Nissan... YET!) and have heard that a yota engine is even more reliable at high HP (looking for 600 or so) than the great Nissan engines....

I'm wondering total price..... engine/trans/wiring/ecu + any items needed for the swap (possibly done myself with aid of a friend) + little assorted things....

price to "hop up" the engine.... taking it from stock to high HP is somewhat important, but looking mainly at the cost to get it in and running. Please compare prices to go from stock to... lets say 600hp if you have that info too!

Not trying to hijak.... just trying to ask some specifics and keep from having to start a new thread (though I will if you guys think I should)

Thanks a ton!!

[rbsileighty]

If you are doing the labor and fab work, then the least expensive might be a draw between the two motors. I would say that the RB would be the least expensive if you are having the swap done. This is due to the knowledge already known about the swap.

If you really wanted the Toyota motor, then you might want to look into a MKIII with a 1jz. I would assume you could pick up a MKIII for a similar price as a S chassis Nissan.

[Andrew85cm]

a decent mkIII costs like 3 grand where as I bought my 240 for 600. LOL That is a little bit of a price difference there plus they are heavy has balls unless you are running very high horsepower to compensate I do not see the point in having a mkIII (3800 lbs) 240sx (2800 with motor). They weigh as much as mustangs!~ANDREW~

[s13sr20chris]

the grass is always greener...look at the top secret supra. i know its been brought up many times.
