why should i get a 2jz swap instead of an sr20?

[Black R]

I have a budget of $10k, and I already have an s13 coupe.

Now adding up all the parts, for a 2jz swap it looks like it'll cost $9842.94 in parts alone - without getting any hookups or deals.

We all know an sr20det swap is about $7k less than that!

So... for a 300whp goal, sure an SR swap is the winner, right?

BUT, what if your goal is 500whp or even 600-700whp?

The cost of getting an SR built to those levels is going to equal that of the 2jz swap...

I guess there are three options open to me:

1. sr swap and be done with 300whp.

2. 2jz swap and be done with 300whp. Later add bigger turbo and bpu's to get 500whp.

3. sr swap for a while, then later change over to 2jz swap when I want 500whp.

Thoughts?

If you cant afford the 2JZ why not use a RB series. They can be had for 2500 bucks. And you can make that 500RQHP in time on it

[TotalDPerformance]

The 2JZ can be bought for around 2500 as well. The cost for an RB is going to cost around the same if not more honestly. I'm sure your talking about rb20/25 though not 26.

OP: First figure out your goal. If its over 500 then Id be more inclined to rb/2jz either of those, the sr can do it as well. I went with a 2jz and honestly I thought it was the same as you 9k+. Well added a bunch of pluses to it. I'm cureently at around 15k and thats not inculdint the car and its everything I need and nothing really more. So make sure you do all the searching you can, ask more questions. This swap can be and will be expensive. I wish you the best but if your budget is 10k go SR, becasue your deff going over with 2jz. Hope this helps alittle.

Find me a 2JZ 6 speed motor set for 2500 and Ill buy it right now. 2JZ with 6 speed run over 3500-4000 maybe with an auto and high mileage you might get one for 2500.

[OutToWinPAHC]

I dont know the toyota engine codes I think its a 2JZGTE, they run about what blown says 3500+ iv seen up to 5500 with lower miles and a 6 speed. You may be talking about a NA 2JZ from a IS300 for that price.

But the RB25DET is not a hard swap in that, just do your reading a head of time. But you should be able to get the engine for 2500, and into your car for another 2500-3000 with some goodies. Then build in time.

[TotalDPerformance]

BLOWN: First of all, no one said anything about using the six speed or any transmission for the matter, second most people that use a manuel ,use a mk3 transmission for the swap, third I bought mine for 2600 + whatever I spent on transmission and others. So, you can get the motor for 2500 with auto. Im just saying there is no way hes going to do it for under 10k regardless what transmission he uses. Unless he has super discounts.

Im doing the swap now in my car. I wouldnt come here and say anything unless i knew what I was talking about.

Please dont take this the wrong way just making my statement since I am doing the swap right now and im over 15k into it just doing the normal stuff to get it running. Also I have really good discounts so even with that Im well over 10k.

Bad choice in swaps then. I had less than 10 in my motor setup and made 430 NA hp. Another 2K and Id have over 500 whp NA

Yeah I was afraid I'd be over $10k.... which is bad and good. It's bad because it's more $, but it's good because I kinda figured that would happen. Even were I to spend $15k swapping a 2jz in, I think I could stomach that.Of course, I'd prefer to do it for less.

Is it really WORTH it though?

[irocznissan]

actually a jdm 2jzgte can be obtained for only 2200. now a usdm 2jzgte is different. those go for 3k-6k depending on wether u get the 6spd. im doin the same thing. im just gettin a jdm 2j and buyin the usdm cams injectors and twins. and f0r 2500 i got a usdm 2jz. a 2jz swap is far cheaper than a rb26. mount kit is 1700 from tech 2 or just mounts can be got for 400. r154 is about 1k max but can be had for cheaper if ur patient. wiring can be done by yourself or for 450 from tech2. thats it.

[TotalDPerformance]

Man its really what you want. Honestly I'm doing becasue its something I have wanted to do and just stepping in that direction. Its expensive but at the same time there are not many of us out that have this swap. Im sure I could have cut some corners and not spent so much but I like doing it right and having nice well made parts then just doing it ebay style, you know what I mean.

To me, Yes its worth it. But something thats worth it to me may not be for you. Take your time think about. Put all the swaps on paper and see what fits your goals better and your pocket, then go from there.

Hope this helps you and others out there.

So you got a JDM 2JZGTE for 2200 and cams, injectors, and turbos from a USDM for another 2500? So 4800? The RB26DETT I purchased last year was 4000 with the AWD trans and all of the goodies. R32 crossmember, some wire (wiring specialties about 350), drife shaft, fuel system and RB26 S car. Much cheaper then 10000 and if you go with a RB25DET you can pull it off for under 5K and have pleanty of cash for upgrades

no are you crazy wat cams u know are 2k. the motor cams injectors and twins are 2500.

[irocznissan]

a 2jz setup is just waaaaay better. u start off with more....usdm 2j of course. and u can end up with a lot more wit simple upgrades. 500hp is easily obtainable. 700 is easily obtainable. show me an rb swap that can get 500 hp for under 10k without touching internals.............. illl answer that for you, none!!!

No your English was not that decisive so its really hard to tell what you were talking about. You through out 3 numbers in that one statement. Perhaps you should clarify what you said then.

IE... 3-6 K then you said 2200, then you said 2500 so its realy hard to explain. Then 1700 for premade mounts, and 450 for wiring.

So with what you said about using the JDM engine with the cams and turbos that you said were 2500 plus your mounts, and wiring you have one hell of an exspensive swap that is nowhere near 500 RWHP yet. the OP said he was looking to do the swap for under 10K, it would be nice to see him do that with money to spare for the this and thats they we occur.

But let me ask, 1700 for mounts, are these things made of gold or something?

[irocznissan]

my english was clear. and add it up 2200 for aristo 2jzgte. 100 for usdm cams 100 for usdm injectors and 150 or more for usdm twins. lets do some math 2200+100+100+150=2550. 2550+1700 for mounts + 450 for wiring= 4700. 4700 + 1k for soarer r154= 5700 under 6k. =) done! swap is done and in the car

and as for mounts being made of gold. read and do a bit of reasearch b4 saying anything. i clearly said mount kit. meaning more thatn just mounts http://tech2motorsports.com/te....aspx

Yes, BUT what about the AEM EMS, ALuminum radiator, fans, exhaust, downpipe, FMIC and piping, SAFC, tach adapter and speedo adapter so gauges work, etc?

Assume I'm buying a GOOD Motor and I'd still be replacing the oil pump, timing belt, water pump, cam seals, rear main, front main, tensioner, headstuds, and so on.

I can see where the prices are going up and up and up.

[RCA]

Sry about that forgot to add the water pump and belts =/

You guys are all silly gooses. A soarer r154 for 1k is ridiculous. You get um for like 1.8k... not worth it. You don't need an AEM EMS, usdm injectors or cams. You don't need to replace the oil pump, cams seals, rear main, front main, tensioner, headstuds ect. If you are buying a motor set that need these to be replace then you shouldn't buy your motor there.

A stock bones Aristo in a 240sx with FMIC and cat back dynos at 350whp

Aristo 2JZGTE:$1600

R154 + shift linkage extention:$700+250 (optional $300-$150 for bellhousing if you got a 7MGTE r154)

Clutch kit:$700ish

Flywheel:Free-$350ish

Swap kit (non ebay):$1500

Water Pump:$250ish

Belts:$75Wireing: $550

Ratiator:$280-$450

Fans: $200

FMIC:$600

Fuel Pump:$100

Misc: (should cost around $250-$300

Then you need to find a fab shop that will help you with welding the factory 2jz throttle cable braket.

Heater line & cuplings for the heater linesPower Steering lines (not hard lines)Many little clamps for the heater line/steering pump lines set up.

Radiator hoses

Some stick pipe to be used for fuel lines

Fan control box or a thermal control which for thermostaticly controling your fans (unless you want them hard wired and the fans always on)

Well the math is done and we are looking at $7625 swap (parts only) that comes with: Fidenza lightweight flywheel ACT stage 6 clutchKoyo radiator (with moded inlet to use stock supra hoses)Spal fansTransmission Shifter fits dead centerA transmission with a 700hp ratingAnd an engine with a +1500hp bottom end + 800hp rating on the stock internals + 500hp rating on factory turbos.And finnally an engine with an God-like torque curve.Also RB replacement parts come from japan... that is a long wait for parts.

PS you could save a lot of money if you go with the 1992-1996 Toyota Chaser or 1992-1996 Toyota Soarer motor set. It comes with a 1jz but it also come with the R154 trans that doesn't need a bellhousing or a shifter extention. The sets sell for 3k-2.2k

PSS if 500hp is your goal swap a LS1 engine + full exsaust (headers + no cats + cat back exsaust) and some aggressive cams. It will come out cheaper.

No cats helps, headers are usually already custom, very open exhaust, and there is only 1 cam.

Yes, duh, what I thought I said and right. One cam on each valve cover? Or am I thinkin SOHC instead of OHV?

If I am not mistaken, isn't the LS6 in the C5 Z06... if so, how much did the engine cost?Was it used? Or a new crate LS6

If you want to get down to it the LS6 inst much different than a standard LS1. Heads/Cam/intake/oil pump were main differences but all things you replace on a build so it doesnt matter if its a LS6 or not.

[OutToWinPAHC]

Single cam engine,the valves are overhead, the single cam operates the 16 valves

[RCA]

Ah good stuff. But isn't the bore & stroke diffrent on the two motors?

Yea I went to Howstuffworks and searched OHV... learned a lot... but the LS series engines could unlock an ish load of power if GM engineered at S/DOHC system. The OHV set up seems so archaic, it limits the engines abillity to rev higher. So less potential HP =(Oh well thanks for the info!

[OutToWinPAHC]

They just don't need to, they did it with the old ZR1's. But aftermarket LS based engines make 2000+ hp, and have seen them rev up to 9500RPM. It cost a hell of a lot however. Most LS vehicles sold are just driven, most people are more then happy with stock power. Every car and engine has room for improvement, But as blown said, head, cam, valvetrain, bolt ons and a tune will make 500+ RWHP on a LS1
