Anything is possible, but why would you want to. The S54 is not as good as a tuned N54 and the S65 would be very expensive.

Pretty much, you can squeeze a reliable 450bhp out of the N54. Why would you ever want a S65?

because of the high rpm and V8 sound, and you can squeeze even more power from supercharging the S65

If E89 Z4M existed with this engine, I think people would buy it...

It is going to cost $$$ OP, and I have not seen it done.

Can probably go buy a 911 for the same price as this mod.

Google Manhart performance, they do the older m3 as long as v8-v10 transplants on the e89. He might have the 23i guys

Yes I agree, take a look at Manhart. Laugh and then move on.

You would have to be absolutely in love with the design of the e89, or be getting it or the donor car gratis from somewhere for this to make some sense.

But just so you know, any car that does not have a front mounted inline 6 is not a real roadster in my book. Ok ok, a V12 would be acceptable as well, but why would you need such a long bonnet if you were to use a compact V6 or V8 anyway?

Not many engines out there with a linear powerband like a S54... People need to stop looking at just peak numbers unless you're looking for the highest number on a dyno.

Both are completely possible, just need to get a standalone that works properly.

yes S54 is not good as S65 but im thinking buy S54 or S65 engine and make supercharger upgrade. and it will be more than 500hp.

because i didint find best supercharger or turbo kits for e89.
for example G-Power or ESS they dont have any engine kit. only have ECU update.

does anyone make turbo upgrade do you know how many powers get on e89 3.5 N54 engine?

Yes. RB turbo, Vargas Turbo Technologies, Vishnu-FFTEC, ASR turbos.

They all make turbo systems for the N54

Oh, also Manhart makes turbo upgrades. Manhart is good, they are considered a good tuner/engine builder in Germany.

I will PM you info with another very good reliable solution.

This. A Z4 with the S65 would be ah-may-zing. Slap on the M3 suspension parts and it would be a historic car. The sound of the S65 upwards of 5k RPM is unbelievable.

One reason would be able to do a 'front mid-engine' design, so the car will rotate more quickly

Speaking of.. OP.. if you are seriously going to throw down this much money on a German convertible engine swap, how about getting a GT3 engine into a Boxster....

Plenty of room for the v8 but let's review the math once again:

s65 + tranny + all supporting components (radiators, a/c etc) 6-7000 euros if you're lucky

revised harness + unlocked ecu + integration of dashboard readings 5000 euros by awron.de (these are the guys manhart collaborate with for electronics).
You could get away with half the price if you choose twincam.co.uk for that matter with a standalone but don't because this is not a race car and you want to have a working dashboard I presume.

1000-2000 euros mounting all that stuff back together in an independent shop plus new engine mounts and plus a new custom cut and balanced driveshaft (add 1000 euros).

By now you have reached 15.000 euros in a best case scenario without even touching the diff, driveshaft and rear axle which will require a ton of modification if you select e85/86 m or even e92 m bits in case you won't add a quaife unit and call it a day.

And then when it breaks down, which it will, the repair costs will be significant to say the least

at that point, it is an OEM drivetrain. The mounts and driveshaft are the only customized parts.

Shouldn't be any worse than E9X M3

Also, what about starting with a 20i or the smallest engine possible or a 35i or 35is with engine troubles to keep the cost of the body low.

It is not a bad idea, particularly in europe, where car prices are hugely inflated vs. US...
