I just picked up an fd, no motor or trans, which is a good thing because there was no way i was going to keep the rotary in it anyway, i love rxx7s body lines and suspension set up but i cant stand that motor. Im pretty familiar with swaps, ive put together a 1jz supra, an rb25 240, a few v8 datsuns, a v8 fc.. etc.. my current car is a 7mgte powered 74 datsun Z. So making mounts and stuff like that is not a problem.

so i was planning on doing an ls1, however i would really like a turbo motor and i dont really want a turbo ls1 so question is, has anyone tried,measured for putting in a vg30dett from a 90 plus 300zx twin turbo? I was thinking the only problem i could see would be the turbos since they may interfere with the steering stuff but with the room you save having two less cylinders sitting forward you could mount them in front of the engine right? Any extra thoughts on this?

 

Interesting. I know of some people doing the Buick turbo V6 swap so I don`t see why the VG30 would be any harder. You should check out www.torquecentral.com and check out their links.

Would be another site to visit as they can probably make the craddle needed to mount the engine. Good luck.

RB26DETT. Enough said?

 

dont take that to sevenstock you'll be laughed at. just get rid of the car if your not going to put a rotary in it,

 

Oh no. He's not going to get laughed at is he?

What an argument against doing an engine swap. I don't want to be laughed at.

Anyways, what's up with your recent string of posts?

Are you just going to post in everyone's conversion threads and tell them that they're:

1) A hick, or a good old boy

2) Only doing the swap because they don't know how to work on a rotary engine

3) Goingto get laughed at if they bring their car to sevenstock.

If you hadn't noticed, this whole section is for people doing engine conversions. Maybe you should stay out of this subforum if all you can do is flame people. You're not going to change anyone's mind by telling them they'll be laughed at.

 

Rofl@ricerbuner... Obviously his chosen screen name automatically voids any credibility to his name. He probably doesn't even own an Rx-7.... Repair bills pile up and unless you're sponsored or have outrageous amounts of money to just throw away, the rotary is the worst engine for daily driving. I know the N/A guys will say differently, but who wants to be slow? The only way the N/A guys go fast is with displacement or stripping the car to the ground and riding on metal with no luxuries whatsoever.

 

ehh, vg30dett isn't a great motor.... it's got a lot of power stock, but limited upgradability/cost ratio...

RB25DETT, cheap, readily available, and AWESOME potential. Much stronger bottom end then the VG, and they're honestly getting pretty common to find parts for anymore (with all the importing done....)

It'd be a cool setup either way (the rotary obsessed guys will hate you though, they really hate me, I'm putting a stupid, heavy, pushrod in my 86....)

Oh yeah, better take pictures!

 

I think all vehicles should have atleast two rotors and one turbo

 

I think even the dimmest person should be able to find their way back out of the Other Engine Conversions forum without posting if all they care about are rotary engines. There are plenty of other forums to choose from which cater to that sickness...

 

nissan engines are really nice (for piston engines) especially the rb series, rb26dett is hardcore....

btw if you dont mind swapping to a sohc, in australia there was a rb30e and a rb30et.... thats if you value displacement over quantity of cams

 

i'm a fan of the rotary engine myself...but i have driven a few good piston engined cars in my time.

never had the chance to drive a VG30DETT 300ZX, but I did have a chance to drive the old Z31 (1980s) 300ZX turbo...very fun car, good rival for the FC back then.

well, IMHO...the V6turbo would be rather heavy...and a bit bigger than you might require. perhaps you should reconsider, and possibly look at the smaller engine class 2.0L DOHC inline-4 single turbo?

it's true that they generally lack the torque provided by a 6 cylinder engine...but they are rather lightweight and have lots of potential. not as much torque, but they do have a higher redline and are capable of pushing out 550HP+

I've driven my friends old MR2 turbo which was a road course car...it was just lightly modded, but it pulled really damn hard whenever you mashed the pedal.

a Toyota 3S-GTE or Nissan SR20DET would be a great swap into an FD, well...at least i think so.

regardless of which engine you decide to put in, HAPPY SWAPPING!

 

high-RPM and from what I understand people get that RB30det block and put RB26dett heads on it.

 

i just like the idea of a twin turbo 3L engine....

just to be pedantic

no rb30det just rb30et
no DOHC

yeah
but you're right
hybridising engines is interesting

i've been told you can also make a ca18det into a ca20et using some aussie parts

i like how interchangeable the nissan engine parts are

i've heard of people using the throttle bodies from the rb30 engines in turbo nissan exas to make them go harder

like i've said before... if i were going for a pistoned engine... it'd have to be a nissan...

 

rb30det(t) = rb30de block + rb26 head redrilled to fit rb30 block + rb26 manifolds/turbos/etc.

If you're gonna do a 3L turbo, you COULD go with vg30et. There's nothing wrong with a single cammed engine. There's also 1jzgte, 2jzgte, 7mgte, 3sgte, sr20det, ca18det, fj20et, the list goes on and on.

 

Build the crap out of an SR20DET and put it in.

The motor is lightweight, moves a car about the same weight and it's very short as well. TO my knowledge, it'd been done once in the US, so that means you can do it again.

I'd put another rotary in. But that's just me.

 

and nobody has answered his question.........

 

I think the implied answer was "no" on all counts...

 

one could argue that point. i just hate how people get off topic and suggest a number of other options right away without even looking at the possibilities of the original idea. just whoring, don't mind me.

 

If he's done all these swaps, why is he asking us? He should be well-versed on the process by now, I'd think...

 

he knows his ****, don't worry. however i can not answer that question.

 

you'd think right. Just wondering if its ever been looked at. Before I tore down the z32 donor vehicle, i was looking on here to see if anyone had tried it, what problems they found so id know to be ready for something. Ive thought of doing straight 6's, its just NOT what i want to do. Id rather put a v engine in it, it was just my choice. z32 motor sounded fun. at 350ish rwhp a vg30dett has a faster powerband than a supra motor, and if i were to go l6, it would be a 1jz. I asked you because if there was one place where someone would know if its been tried, it would be here. I have actually gotten rid of the car, needed money for some other stuff, but im sure ill try it later. They Idea wasnt that I needed your help, it was that i was asking for a heads up.

 

No I don't think a VG30det into an rx-7 has been done before. I looked for information on nissan engine swaps into Rx-7's and the ones I found were 4 cyl ones. However not being afraid to make my own way I'm doing a nissan V-6 into an FC (VQ30de-K). I had looked at a VG from a 300z for awhile and it might be a good choice but I would definately look at the length of the engine. With the intake runners sweeping behind the valve covers it may make the firewall clearance tight (I know when a VG turbo is put in pathfinders it always is). Yes the V-6 is 2 cyl less than the v-8's but most V-8's that are used are push rod's and are apparently much shorter vertically and therefore can be placed farther forward without hitting the hood.

Also the front sump clearance with the steering rack may be an issue. Again that vertical height problem again. However, with enough cutting and welding though just about anything will fit

 

no vg30det`s where in any usdm cars. only `de and detts.

i too an really thinking about putting a s13 black top i have in a 88 GTU that i found for pretty cheap. i have seen the FD from Talli Fla that has a s13 red top in it, and it was on E-bey recently, but i was wondering if any one with a FC has done this swap too...

and like what Majik16106 asked. i m just looking for a heads up of things to look for.

 

yeah, the sr swap has been done. it's short enough to fit with tons of space leftover for the rad. and fan. however the oil pan can interfere with steering linkage and the subframe, depending on how you make your mounts. you'll also need to remove a chunk of the metal lip sticking out from the firewall. it's there for water protection so removing it will not cause any major damage to the strength of the car.

 

sweet, any pics around? the google search i did, didn't bing up much.

TIA.
