V8's aren't really my thing, but the inline 6 supra engine with the twin turbos is just plain awesome. They have such huge power potential and sound very sexy.
I'm sure someone’s got one kicking around here with the swap. Curious how they like it? Pictures would be awesome as well!
Rotary is still #1 on my list but just want to see what others have done or thought about. Please don’t turn this into a war.

Thanks

today, i saw a nice low mileage tt engine with tranny at the track today...sooooooo close in buying it but the company selling it are only 1 mile from my house so i can just go there instead track was like 40 miles away, and i had no way of bringing it home haha

Thanks!

I registered and will post up a few pictures of the swap off there website on here.. Looks pretty cool. I imagine there was quite a bit of work involved.

a supra engine is a fine engine, however, the LS1 is also a fine engine. although i do not particularly like corvettes, i am not a fool and understand that they are very capable and even more so reliable under high horsepower applications.

Well heres a Supra motor on my boy FC3S... The thing is a monster....

The 2jz in the FD is A LOT OF FUN! The twins just did not do it for me...right now I am undergoing a HUGE single turbo swap!!! The car is very quick, drives easy and sounds great.

I am pretty sure there is not going to be a kit sold for this swap...I feel there is not enough interest for somebody to actually produce one. Honestly, the swap is not that hard if you can weld and solder. If you want any details, just send me an email at supra7@gmail.com and I'll help you out in any way I can.

I think plenty of people are interested in this swap, myself included. I remember the buzz when SP's Supra 7 hit the scene.

The problem is, it's a new swap and there isn't a ready made 'kit' available. I mean, the words custom fabrication are not words you want to hear when on a budget. I'm all ears to anyone that has performed the swap and put a few thousand miles on the car..

i've done it, very easy kept the stock rx sumbframe made brakets on it and i'm using the supra motor mounts,wiring is a breeze the supra harness jus needs 12v and it already grounds it self on the motor i jus need to to give it batt 12v ,ign 12v , and a 12v constant for the ecu memory.never used the twins though went single from the get go.jus got my drive shaft a week ago,where i mounted my motor it even kept the dri shaft stock length jus added the supra front yolk onto my t2 shaft.but if u go single u need a mani that keeps the turbo close to the rear of the motor cuz bigger snails will hit the compressor on the hood.check sig

Uh, that engine says NISSAN on it. Definately not a 2JZ. Looks like the engine from a Skyline, don't know the code though.

TurboII RudeBoy

thats an rb25 det out of an skyline gts-t stout motor stock bottom end can handle a lil over 500 but the factory piston's ring lands are weak and take a **** aorund there.Personally i wouldn't put an rb in an rx7 unless it is fully built , even the rb26's (skyline gtr) have oil ing problems when u rev em upand beat on em, thats why i went with my toyo motor. if you like the nissan motor and want the least problems look for a late r33 or r34 rb the r32's tend to eat their cranks

What's the weight distribution after a swap like that?

rg42284

weight distribution would be greatly affected as the iron block of the 2jz would add at least 100 pounds.

and its sticking past the front axles, But im interested in the balance numbers mikeys car puts down when he's done

Nihilanthic

Would the oil pan interfere with the steering rack? Ive heard many a flamewar about the dangers of not putting a tie-rod kit on if you move the steering rack because of dreaded bumpsteer :P But yeah you might have issues with oilpan/steering rack clearance. I also dont know how TALL a 2JZ is but it shouldnt really matter unless its so long that it would reach where the hood starts to slope down. The Ford v8 guys sometimes have distributer clearance issues because they have it up front instead of in the back like the Chevy v8s do.

Honestly tho, having a lighter car to put a giant turbo on will help with streetability, just PLEASE dont put on some too-big turbo and make a highway queen out of it!

P.S. - all this weight difference **** is irrelevant. Do a search for "kukri" here on rx7club and see what hes done with his iron block chevy v8 FC.

TurboII RudeBoy

i rate my car like a 3 rotor swap towards balance becuase only the first 2 pistons are past the strut towers, also my motor sits low i mean in my fc the valve covers are only like 2 inches above that ridge line that runs along the fc firewall.With the right suspension and planning where ur motor will sit ur car should not be that affected to where you can't due what u 've done on a road course with the rotary.


oo **** i jus noticed fd strut towers are farther back than fc's i wonder how those fd swaps handle for real

Mikey

The oil pan is not a problem for the stock FD placement of the steering rack (so no bumpsteer). I was able to mount the engine quite a ways above the steering rack and still shut the hood. Granted, the stock hood has to be trimmed to allow cam gears and stock twins to clear...but you do not have to cut a hole through the hood.

As far as weight difference, I have not noticed anything different in the way the car drives. However, I do not auto-x the car at all.

My guess is that you have absolutely zero first-hand experience with RB motors. After driving a '95 GTS-t for a couple of months, with high boost on 91 octane, I have good reason to doubt your claims of weak piston lands.

TurboII RudeBoy

bro go to any nissan forum or nissan shop that works on rb's and they'll tell u on the rb25 the first weak point in the motor is the factory pistons.i had an rb25 to go into my rx7 and for my goals the 1j was better bang for the buck i can easily break 750 -800 hp on 1jz factory internals where as i would have had to tear down the rb fix the oiling probs they have at high rpm and change out the pistons, i'm talking out of experiance and not "internet knowledge", because you drove a skyline for a few months "high boost"? how much boost were your running? what turbo set up did you have? *** on i can turn the boost up on my 1j to make 900 plus hp the motor might make it but will it last no. My family and friends have been building motors for several race teams in and out of this country so i think i know what i'm talking about.

RB25


Pros

-good potential (500+ on stock internals)
-VVT
-strong tranny (also include this when you price rb25s)

Cons

-expensive clips (when you get that strong tranny)
-becoming rare and expensive parts
-weak pistons ring lands

does that make u feel better

rarson

Ha! You are the one with the internet knowledge. "bro go to any nissan forum or nissan shop that works on rb's and they'll tell u on the rb25 the first weak point in the motor is the factory pistons." You HAD the RB25, but you didn't actually use it, correct? So therefore you would know jack **** about it. As for shops that "work on" the RB-series engines, there are none in the US certified by Nissan. These engines aren't even common enough for very many people to have extensive knowledge of them.

Of course, if you check out some of the Aussie Skyline boards, then you'd read some real information about people who've actually been tuning these cars for YEARS. I've tuned and worked on the very Skyline I had driven for more than 2 years. We've been running it at 1.5 bar boost (that's 21.75 psi) on 91 octane every day for the last 2 years. The turbo is an Apexi AX53B-70, don't bother looking on their US site because it's only available in the Japanese market. HKS intercooler and BOV, Apexi GT-spec exhaust and downpipe, Nismo fuel pump and 800cc injectors, Apexi AVC-R and PowerFC with the FC Commander. Does that satisfy you?

A vast majority of internet racers who come to forums talking about 900 whp cars never even get to 500 whp, let alone 900. So I don't know why 500 whp isn't enough for you, but I guarentee the stock RB25DET bottom end will take you there. By the way, I don't know if you've looked lately, but RB25 clips are a dime a dozen. They are CHEAP nowadays. Most of the parts for the R33 are interchangable between the S13 and S15 Silvias and the 300ZX.

If you want 900 whp, then you really shouldn't be worrying about bang-for-the-buck. You should be worrying about producing that power reliably on whatever fuel you choose to use. In that case, I'd just get a 1UZ-FE, build it up and throw two turbos on it. The 1UZ is lighter than the 2JZ anyway.

TurboII RudeBoy

ey i never knocked the bottom end of your motor i stated that your ring lands are weak, which is true because i had an rb in a 240, and 2 motors , everything holds up in the stock motors but the pistons and the oil pumps.not trying to start a flame war just stating what i know from experiance.the internet knowledge that i posted is from a nissan forum where tons of rb swaps have been done and even nissan owners in aussie land will tell you whats up.as far as what you have done to your car your full discription is better now, and unless ur turbo kit is outta production you can get ur turbo kit from apex'i japan. i never stated 900 hp, it was 750 to 800, a stock rb25 with a mani and big single will break before a 1jz period.and i'm no internet racer, havin personally had a hand in building the only running 3 sgte 2k1 body celica whihc is now a 750 plus horsepower vehicle and the first official scion tc in the 13's 12's and 11's both vehicles winning several trophys and magazine coverage with a full spread in hci and modified mag

LookThatsMe

Thats an Rb26 i live liek 5 min away from the shop and seen it... you could go on acotsamotorsport.com they do the sawp i think they said either 70 or 74 thousand dollars lol... 800hp low boost and 1000 somthing high boost everything included
