Wondering if anyone has done it or if it would even fit. I was just thinking about engien swaps and instead of SBC like everyone else, i thought i would try to be more unique!

What do you think?

robtechfabrications

why would you swap an oldschool supra motor into an rx7??

sLoW'n'StEaDy

why not?
i could swap in a SBC with pretty much the same amount of power, probably about the same amount of work, but not unique in any way. Plus 1JZGTTE is way more fun to say then "small block chevy"

Why can't the engine names be simple like "13B".

twilight slide

most people refer to them as 1jz which is simple. Why go 1jz, though? Besides the "unique factor". There is a thread where someone did this, and the oil pan work didn't look fun. Really though, how are SBC swaps *in a rx7* not unique. It's not like there are tons of them cruising around. They will be laughing all the way to the end of the strip since they have tons of support and 1jz is not going to be the funnest engine to find parts for.

Why dont you just leave the 13b in there, instead of ruining a perfectly good rx7

sLoW'n'StEaDy

Im not doing anything right this second. However the amount fo money i would spend trying to make a 13B fast i could buy an engine/trans, end up with the same power and probably save money.



twilight slide- Boondock saints is a kick as movie!!

why do a 1jz and not the 2jz?
when it comes down to it the 2jz makes more sense in my mind

Buy an s5 T2 Motor/trans from Osokajdmmotors.com , buy a microtech lt-8s ecu from someone, have it rebuilt and streetported from banzairacing.net , and have your self a sweet ride!

.................................................. ..................like I did

a few more parts needed but not much, fuel,exhaust, ect.

There was one of those on ebay the other day. it must've gotten sold. I've never even seen or heard of a swap like that until i saw it. Anybody else see it?

monkhommey

i say go for it. 1jz are cool also. plus you get a couple things you will hardly ever have at the same time in an rx7: torque, power, reliability, and ok fuel economy!

apparently you haven't been to cali before, SBC 7's are starting to take over in this state.

robtechfabrications

its all about the 20b

1JZ is just as simple as 13B... the GTTE is pretty much understood.
I don't know about the other guys on the board, but I've seen more then my share of smallblock swapped 7's. Living in VA, pretty much any odd RWD import in local-yokel hands ends up with a smallblock chevy in it.

sLoW'n'StEaDy

Yeah, there are 2-350 carb'd RX7s and an LT1 RX7 within about 30 miles of me. Which is saying something since i have only seen MAY BE 4 or 5 including mine!

plus 300HP froma stock engine shich i can get for $590.... seems worth it to me. How much are 13B's sellin for now days? I could probably sell my engine and trans and have enough to buy the 1JZ...

Little tidbit. The engine designation isn't "TTE" Nissan is the only japanese manufacturer to use a "T" designating a turbo so then you would have 2 "T's" for 2 turbos. Toyota is simply "1JZGTE" or "4AGZE" or even "3SGTE".. I am not trying to bag on you, but if you are going to use a designation, might as well say it right. I just told this to a guy who has done that swap into a mkIII supra last night.
On a side note, one of the nicest sounding L6 motors I have heard.

i did this swap and it's been running for bout 2 years now.starts up every single time, great tourque, crazy horse power potential, parts are sill in production, most 2jz accessories are the same, pistons and rods you can order from eagle, crower or wiseco, you can even use 2jz pistons.corwer makes 1jz cams now.i'm in the 700hp club with no standalone just chippd ecu with a greddy emanage, injectors,upgraded twin turbos and 25 psi on stock internals.

Last time I was in cali was before I could drive :P. Still though, I am the only one that thinks its lame to swap an engine cause it's "unique". Anyways good luck if you go for it, be sure and post up some pics

Written by my son awhile back...... pretty much says it all.

Every time I read one of these threads I just sit and shake my head. "you killed your handling...you took the "soul" out...it would lose to its non-piston counterpart" etc, etc, etc. I guess ignorance is bliss. I can guarantee that NONE of you have ever ridden in or seen an LS1 FD in person. Let's address these one by one...

1)You killed your handling-
Really? How so? The car retains its 50/50 weight distribution after the swap seeing as the weight between an LS1 and a 13brew with the turbos/intercooler/etc is about 30lbs. Move the battery to the back (which you have to do anyway), and the car is just as balanced as it was before. I guess you go into everyone's thread posting about the stereo system they put in their FD and start posting about how they killed the handling right? This conversion does NOT kill the handling. The car still handles the same. The CG of the engine post/prior conversion changes about 1.5%...meaning that if you had a professional driver driving both cars, he may notice the absolute slightest of difference...however the extra 200 ft/lbs of torque to get you out of the corner MORE than makes up for it. In other words...an LS1 FD will beat an equivalent powered rotary FD around a road course. It's called area under the curve...look it up.

2)You took the "soul" out.
Yeah, I guess you're right. He took one of the most finicky, unreliable, gas hogging "souls" out of the car and replaced it with a more efficient, reliable soul. Did I mention that it makes well over 400 whp N/A? AND gets 30mpg on the interstate? Are there any rotary FD's that can do that? Nope. 400whp FD's are few and far between. Yes, they are out there...but the vast majority of those that have the mods capable of doing it, either aren't tuned correctly or aren't running correctly. I have every bolt-on there is on my FD, including a PowerFC, intercooler, etc, etc, etc...and my car would absolutely get RAPED by 2hotrod's car. So I guess some people are content to keep the "soul" in there. I obviously have my 13brew still, so it must be for a reason. I understand that you like the idea that it makes the car unique, etc. But guess what, the car with the LS1 conversion is even MORE unique.

3)It would lose to its non-piston counterpart...
Not a chance in hell. A very mildly modded LS1 will make over 400whp to the ground. I know there are a few 500+, even 600+ whp 13bs running around...but like I said before, not many. For those, a simple 150shot would probably do the trick. Or, you could go all out and to a turbo LS1...then its all over. How does 800+whp and 700+ft lbs in a 2700lb car sound? The LS1 has WAY more hp potential than any 13b, swap in a 20b and mod the **** out of it and now you might stand a chance. (Of course, they WOULD be killing the handling and 50/50 distribution of the car since the 20b is WAY heavier than an LS1...but you knew that right?) Hinson is working on a twin turbo monster as we speak. The car will hit 1000+ hp and will most likely run 8s on pump gas, and we're not talking about a stripped down car, or a tube chassis or anything. Its an honest to goodness "street" car. I guess there are 13b powered street FD's running 8s on pump gas? riiiiiiight.


In summary...you all have the right to your own opinion (even if you are misinformed or wrong altogether). But try to at least have a little bit of knowledge about this conversion before you step up and start bashing it. My guess is that everyone here who just bashed this car would get there asses stomped by it, and afterwards would be crying about how they don't care if its faster, theirs is better because it still has the "soul" of the Rx7. Or how they don't like the sound of an uncorked V8, they prefer the sound of the uncorked weed whacker that an opened up 13b has.

If you were comparing a moderately powered 13b, I would probably say you are close to having a valid argument there...as a sequential 3rd gen's power at 4k can be pretty decent compared to its peak. However, we are talking about 400-450whp 13bs as compared to a 400-450whp LS1. (which will rev to about 6800-7k btw, so its not as shallow as you think) Take a 13b with a ported motor and a t78 or the like. The cars I've seen aren't even at full boost yet by 4k, and are only making in the 230hp range...if that. Are they as peaky as a 4cyl Honda? Of course not...but they don't have the area under the curve like a V8 does.

If you had a 13b with power only between 6 and 8k you would have a point, but most 13b's at least have a good 4k rpm powerband, and that's all you need for road racing.


True to an extent...but even in road racing there are times you come out of a low speed turn and the low end grunt will help. There is a thread about this in the "other engines" section about road course testing an LS1/FD. Besides that...how many of the 3rd gens on this board do you think would survive a day of road racing? Spending 30+ minutes at redline or near it? How many owners do you think would sign up to go do that? Not saying there aren't any...because obviously there are. However, most 3rd gens are driven on the street...and the street only. So unless you drive around everywhere on the street banging off the rev limiter...then yes, low rpm horsepower is a good thing to have.

So, in summary...if you ever get the opportunity to drive an LS1/FD, please do it, even if you would never entertain the idea of swapping your Rx7. It will help you to understand better. I used to say the exact same things you are saying now until I got behind the wheel of 2hotrod's car and drove it. It will slam you to the seat in any gear...at any rpm INSTANTLY, and hold you there until you shift. Don't get me wrong, I like the feel of "boost" but the difference is substantial. As far as racing goes...I'll take a 2k-7k power band over a 5-8k power band any day of the week.

OH... i thought there where to versions, the 1JZGTE (single turbo) and a 1JZGTTE (twin turbo) my bad. The one i am looking at is twin turbo.

Sorry 4 teh ignance

woods420

i had a 1jz in my mklll supra and on stock internals and twin gt28s i had around 500 crank hp on relativaly low boost.

twilight slide

Just curious, for how long?

sLoW'n'StEaDy

Hey, i found i nice used 5-speed trans from a 7MGTE. I am told it will work fine with on the 1JZ as long as i get a 1JZ bellhousing. I cant seem to find any 1JZ housings, but i have found a few 2JZ housings, will the 2JZ housing allow me to bolt the tranny from the 7MGTE to the 1JZ?

m5q8

Ok
nice to see your car with 1jz
but from whare you will get the subframe for your FD ?...

sLoW'n'StEaDy

I will get it from my FD. Stock subframe, suspension and evrythign will be used...

back to the trans/ bellhousing question
