LS7 on a Fairlady S30 - has anybody done it or seen it?

[JB-BMW1989]

It makes me wonder why putting the most powerful GM engine on the Nissan S30 model would or wouldn't be possible, so I got you guys to discuss about it. How fast can a LS7 powered S30 be and what's its maximum output when heavily modified? Has anybody done it or seen it?

Explain.

 

[Jay]

LS7 is not the most powerful GM engine for starters, and of course it would be possible. Also the LS7 is not the greatest option out of GM for heavy modifing, not by a long shot.

 

[Jim Prower]

Twin-Turbo L28, bored out to 3.0L. Blue paint and black Wantanabes, as well as a suspension setup with an intent to kill, while you're at it. Maybe some Yokohama plates.

I think I've seen a LS-1 S30 Z somewhere, and I know guys put built smallblocks and the like in their drag cars.

Take your pick of:

a.) What Jim Prower said
b.) SR20DET
c.) RB26DETT
d.) 2JZ-GE with a big turbo
e.) LS1
f.) Blown Ford V8
g.) Big turbo and intercooled Mercedes M103

With:
Riveted fender flares (mandatory)

Clear headlight covers(optional, but highly suggested)

Deep-dish RS Watanabes or a Japanese wheel of the same vintage that oozes with similar amounts of cool.

Of course it can be done! There are people that put 350s in Datsun 510s. I think a V8 Z is well within reason.

 

[Jim Prower]

I'm fairly sure there's something big and American in this.

A 350 fits nicely.

But, hell, I'm the type of guy who prefers Nissan cars to have Nissan engines

My older brother told me it's not possible to have a LS7 on the S30 because it's too big and making the Z's front heavier. I think he might be right... hmm, very hmm. The LS7 is a large engine and a small block, but a 7.0 liter on the S30? That wouldn't fit at all.

I like to discuss this, but what high-test did not listed is the LS6 since it is a higher output version of the LS1. Seems to me it's possible, right?

Disclaimer: High-Test knows absolutely nothing about engine swaps.

An LS6 ought to fit, as it's roughly the same size as the LS1. Right?

LS7 is lightweight, it is a aluminum engine, the block size is not different to LS1 and all the LS series engines.

Just because the internal displacement is 7.0 doesn't mean the external dimentions are any larger.

 

[nd 4 holden spd]

Yep, the LS7 would probably be a better, lighter, more powerful choice than an LS1. Unless you want to start heavily modifying it. LS7 doesn't handle forced induction well because of thin cylinder walls right?

 

[Joey D]

The LS7 is also more expensive, LS1's can be had for hardly anything. Back when I owned the Blazer I ran with a couple guys that had them in their S-trucks and one guy had one in an old Astro van. I'm convinced you can stick the LS1 in anything...there is even a Geo Metro with one that comes to shows.

With that said I have seen LS1 powered Z cars before, I think there was even an article in Hot Rod last year about one. I see no reason why a LS2, LS3, LS6, or LS7 wouldn't fit, you would just need a good rear end and decent suspension.

Quit teasing me. Here's to dreaming!

So you meant to say earlier that the LS7 can actually fit on to the S30 because you can put any V8 engines you want? And as for High-Test, the LS1 and the LS6 are 5.7L, but the output is different. I think they're in the same size.

 

[Jay]

No, I say you can put a LS7 in because there are already LS1's in them, they are all part of the same LS series engines, they have the same external dimentions (besides minor auxiliaries).

I almost bought a Gen I chev 350 fitted into a S30 years ago.

Are you rich? You seem to have owned a lot of cars which would be vey expensive, or at least looked at buying them which shows you could.

I stopped following the evolution of the GM smallblock after the 305..

Joey: It hurt me a whole lot to post that part.. It teases me as well. Want..Datsun...

Rich? No I do ok, but you don't need to be rich to own or buy a S30..... (from memory the 350 S30 was going for 6 grand years ago)

My 71 GTS Monaro is expensive now days but when I bought it prior to the comeback Monaro it was only 3 grand.

Oh, I see that now, VIPERGTSR01. There is a problem while putting the LS7 in the S30Z. The chassis has to be cut a bit while putting the LS7 in the S30. One of my friends at the IRC said it's not easy, but it's doable.

 

[nd 4 holden spd]

All profit baby You could keep that until retirement time and then sell it and never worry about cash again.

 

[Troux]

The LS7 will fit without hacking through the fender walls. A stock-for-stock conversion to a small-block (iron) chevy V8 adds 140 lbs to the Datsun. An aluminum LS1 is going to be almost identical weight. V8s aren't that heavy, they are just given that misconception because they are put into chassis that ARE heavy. There are a number of companies that support the Datsun V8 swaps, and make kits and full conversion manuals for a DIY job, one being Jagsthatrun (https://shell7.tdl.com/~jags/Datsun_Order.html). Things are a lot simpler once you stop speculating, guys.

 

[Jim Prower]

What about a Nissan VK56DE, (Titan) or a VK45DE (Infiniti -45 series)? I know there's been a 350Z swap with the former.

 

[Jay]

We have plenty of Chev/Holden related V8 conversion kits for Z's here in Australia also. Most production engines would be able to be converted into them, with varying levels of modification.

 

[JCE]

I've seen 3 local Z cars (260/280) with small bock Chevy V8's. Gen I, LT1, and an LS1. An LS7 would be possible but I don't think the cost is worth it. I'd rather get an LS2 and drop some forced induction on it or go carbs with a blower.

I <3 my 305.

I've always wanted to stuff a VK45 in an old Z car. The noise is sexy. But so is the VQ35.

I want to urinate in mine, grind it into dust, and melt it into a sheet of metal, only to then shoot it repeatedly with a high powered automatic weapon. and then sell it to the recycler for a little cash. Stovebolt > 305

All the new alloy Corvette-sired 'Gen3' LS-series blocks are the same external size. LS1, 2, 3, 6, 7. There are more, the iron block engine, the new supercharged engine, etc. If you can fit one it, it's more than likely you can fit the others in. I like the LS7 because it's all about smooth NA power delivery.

If you just want gobs of torque and power, go supercharger or twinturbo.

An LS-series engine is all alloy. I'd lay odds on it being a fair bit lighter than the RB26DETT. It's a remarkable piece of kit, a well developed single cam OHV V8. Cheap to make, assemble and tune. Low profile and narrow (no cams on the tops of the cylinders) and not too long - you can turn one sideways and fit it into the engine bay of a Pontiac Fiero by using a kit.

And it's cheap. For power (with torque) per dollar, you're hard pushed to beat it. The LS-series is the cumulative result of 53 years of OHV V8 development. It's gotten pretty good.

 

[JB-BMW1989]

Or either put an i-force V8 5.7L from the new Toyota Tundra and stick it in to the engine compartment of the S30, but that would be stupid, actually. The new LS9 or the LSA can actually fit to the S30 as well. Right now if somebody would be thinking of putting a LS9 or LSA engine on the S30, wait for them to come out in the local junkyard for 3-5 years after the cars' launch date.

cant beat a damn supra not evan a good corvette v8 has a much potential as this beasty engine

 

[Jim Prower]

Wow. put an engine from Nissan's mortal rival in their iconic sports car.

that's a new one.

"zomg only teh 2JZ can support 600 on stock internalzz!!!1!"


So can an M103.

Hey, some car magazine did an SBC powered 2006 Mustang...

 

[Troux]

^600? Record is 1017 WHP (about 1200HP, double what you said) last I checked. The 2JZ is about 170 lbs heavier than an LS1, I believe. Again, it's hard to compare the documented numbers, since specific inclusions for each engine vary.

[Gashlycrumb]

What about the original Scarab V8s? To my mind they must be some of the coolest Nissan Zs out there.

 

[Jim Prower]

A shame about the bodywork, though. Yech.
