Just wondering really, what other engines have been put in Z's?

I know of V8's, Skylines, a beemer engine... anything from the Honda/Toyota side of the world, would that even be feasable?

Thanks :)

How about a 350Z and 6 speed box?

RX7 engines have been fitted

a honda S2000 engine and gearbox would be an excellent combination for a Z,i have seen a MK1 Escort in a ford mag with one fitted and they only had to trim a bit of the heat shield on the manfold to get it to fit so it would fit a Z no problem,240 Bhp and 6 speedbox nice!!!!!!!

Already done in California...and, undoubtedly, elsewhere in the world.

Nissan SR20DET 4 cyl. is popular too.

as far as I know a 2.5 tt out of a soarer has also been done.

We already have a Toyota engined 240 on this forum :)

Anything is feasible, 27ltr tank engine in a Rover SD1 anyone?

I wouldn't fancy a wankel twofourty...

An s2000 sounds very tasty Moggy! :) But no doubt quite expensive!

Ah yes MR F the Nissan Engines, I've heard of but didn't know exactly which was used!

That rover is awful Russ, why would someone do such a thing? :D It'd be fast, but not a looker :D

If I was going to do a swap it would have to be something like this http://www.themustangnews.com/fomoco/st-0511_35v6.htm

We have a racecar 240z running a Supercharged LS1 in NZ. Absolutely insane, massive amounts of torque and hp full stop.

Hi,
Although the Honda motor produces 237hp, it's torque figure is quite low at 153 ft/lbs, so you would have to drive everywhere at 9000 revs!

You'd probably be better off with the wankel against the S2000 lump :) The Zs light, depends how you want your engine to make it's power. Zs tend to be pretty torquey cars so I wouldn't want to lose that and make driving the car hard work (hmm hangon, I bought a turbo Z with nothing much below 3k, d'oh!).

I think stroked RB engine, but set ALLLLLL the way back and with an ally block, so like SR20 weight/weight distribution, RB looks and power :)

My favourite engine would be something like the 1987 F1 BMW qualifying engine, 1500hp from a 1.4 or something running 70psi boost ;)

Wankle ;) ...interesting but sound DREADFUL, less torque than the Honda engine plus it needs a rebuild every 50K and your lucky if you can get 18 to the gallon....on a good run.

An RB30 with an RB25 head is what you need, bottom end is good for silly silly HP as standard, plus its still a straight six Nissan unit. Phone RIPS in Newzealand and you can have one landed ready to go for peanuts, all you need then is a space framed, fully tubbed shell to handle the power.

Wankel all the way :)

The Honda makes 147lbft, the RX8 160lbft, and still does a combined 26.2 in a (relatively lardy) RX-8 :)

How many years will it take you to do 50k in your Z?

The beauty of a wankel is that it only has about 3 parts, so your tuning path is more simple. And so smooth as well.

What I want is two of them, side by side, spinning alternate directions. Or one in each wheel on the back.

Look at this for some rotary acceleration, 600bhp, http://uk.youtube.com/watch?v=fvPfi-ZeQRM

I agree though, RB makes more sense :)

What about a Jag straight-six? The 3.6 in my Dad's old XJS used to make 225 brake in stock form and they were horrible restricted on the air intake so more power was easily available. Pretty bulletproof old lumps and cheap to get hold of I'd have thought. Bloody heavy though I expect :-(

Russ, I used to have a Mk1 Elford turbo RX7 and it was mad mental at high engine speeds but low down was rubbish and I dont know where Mazda got those mpg figures from (lucky bag probably) but they are poles apart from the real world especially when you start tuning the ports

This should give you some idea's what engines to use....:eek:

Mazda got the figures from the RX-8, not a hotted up RX-7 ;)

Neither was I sir, I have a work colleague who owns one (an RX8) and the fuel bill is killing him

Russ

Lying Mazda! Tell him to get a 350, faster and less fuel. Or if he wants to keep his fuel bill a 300zx tt :)

BMW 850Csi V12 and 6-speed in a 1977 z chassis :)
As far as I know we have the only one so far, though a friend as a Jag V12 in a Z

Now that would be impressive. All that extra power and torque squeezed into a small Zed body.

How about a jag v12 5.3 like in this 240 !!

That is mad! Good find, the engineering to get that to fit must have been some feat.

Not sure about the power to weight ratio with such a heavy engine, surely the back will be too light now?

Yep, stick a coulpe of big blowers on that bad boy and you would have some serious power!

Plus you can bore those suckers to 8.1 litres!!!!!

Plus don't they burn oil like a 2 stroke?

Saying that, how would you lift it onto a centrestand (if it had one).

That's the one I was referring to - That is Glenn, he made the headers on that as well and they are wild to look at. The Jag engine is a little heavy for my taste..

here's a couple pics of the BMW V12 in our 280z based ferrari replica. Weight distribution is almost 50/50 as the engine was set back a lot and it's very light for a V12

I'm actually in love with those headers. They're like the exposed ribcage of the engine and look brilliant!

Looks like changing an oil filter is easy! :)

Sorry, getting to this one late...

Thanks for posting Chelle!

I'm sure I've told you before, but this is the most amazing engine swap I've ever seen in a Z. B-E-A-UTIFUL! :)
