a custom titanium motor based on a hemi stroked out to like 9.4L or something like that with a rev limit of around 15k and produces around 900hp natural and equal torque numbers that is also super streetable and gets around 150mpg.. thats the v8 id go with... ohh wait that was in my dream.. but still haha!!

to be honest and ill get flamed, but i always wanted to see a 302 5.0L motor in a fd..

how much does a sr20 weigh?????

the motor itself is around 300 pounds.. then you add turbo stuff.. its comparable to a ls1 or a 13b-rew give or take 20-30 pounds..

Don't know if anyone else has brought this up yet (Didn't read the whole thread) but if I were going to stick a V8 into an FD, it would be this one :D

For those of you who have never seen this, its two 1400cc (Stroked) Hayabusa Motorcycle engines sandwiched together with a custom crankcase ect...

Naturally aspirated specs are:

* 75 degree odd fire V8
* 2.8 LITER, 170 cu. in. displacement
* 84mm Bore X 63mm Stroke
* 4 cams, 32 valves via internal silent chain
* 530mm wide x 485mm long x 530mm high
* 400HP @ 10,000 rpm with stock street cams
* 245 ft-lbs torque @ 7500 rpm
* 200 lbs engine weight
* Billet nitrided steel 180 degree crank
* 4340 H-beam con-rods with ARP bolts
* Billet 6061-T6 aluminum crankcase
* Dry sump oil system with 4 stage pump
* 7.25" or 5.5" Twin disc clutch
* DTA S80 full sequential ECU
* Unique cylinder offset and cam drive arrangement yields a compact design- Patented

So about the same size, lighter and makes more power than a 13B turbo, slap some twins on that and pick up a nice 600+
No need to worry about the rpm's the engine was originally designed to rev allot higher than that.

Oh, and with a price of $30,000 you can run down and pick one right up! Forgot to mention that part...

Funny you should mention that..........check my name. New build in process...:rock:

I know it's not good to quote pics but I think this engine deserves to continue to be seen. That is unfricken believable. It looks like a F1 Engine almost.

Anybody around here have 30k for just the engine?

You could have a fully built FD for less.

Cool idea though just not practical at all.

If I was spending that kind of money I would have one of the Katech engines I quoted before... the 8000rpm 346cu in. LS7 produces a lot more power than that haybusa v8. If you look at the torque curve of that H1...why would you move away from the rotary? It is a great engine, and it is pretty sweet and a really interesting engineering experiment, but it seems sort of halfway between the rotary and a standard larger displacement v8.

Part of the draw for most of the V8 swappers is the fact that it is a little less high strung and a lot more reliable. Moving to a high strung v8 requiring as much or more attention as the rotary seems rather pointless to me. I would just stick with the triangles.

That is my opinion though...

Someone above listed an old F1 cosworth engine for $7k... that could be interesting... but I still hold to what I said above.

i like it! If i didnt already have my ls1 and the full hinson kit.. id be looking for a donor 5.0L engine, and stick it behind a t56 that summit sells for the 5.0L motors.. that would be fun i think! good luck on ur swap n keep us or well me posted :icon_tup:

That Hyabusa V8 is awesome, but a little too small displacement for N/A in a car this size. You see them in Radicals. Might be awesome in an Elise... 200 lb. motor!

the busa v8 is begging for boost.. people are making over 500 on the 1.3's so i would think the 2.8 could make all the power you want. and with its itty dimensions, theres plenty of room for plumbing!
too bad about the price tho.

Would be an interesting project. A little out of my price range though.

Motec controlled boosted busa V8 in an FD or Exige could be a lot of fun. Any other street car chassis out there that could house the thing?

A boosted busa v8 is kind of like the Ferrari F40 engine...or at least in the same vein.

Errr... Your car currently has a 1.3L motor that makes less than the H1 and weighs more...

If I had cash just to go spending willy nilly I would put one dem der in a smart car ----->SUICIDE

LS7 if I had the $. I'd settle for a C6 LS2 either do a crazy NA build or just wack a pair of snails on it.

Honestly in terms of ease of modification, lightness, compactness, it's easily the best choice. And I'm not even a muscle car fan nor do I live in the states.

Look at the torque curve of the Busa V8. Peter's car would be faster up till the busa v8 starts making max power around 9-10k rpm. Peter's car would FEEL a LOT faster than the same car with that Busa V8, because of how the engine delivers torque. Getting a rotary to rev to 8000rpm and make 400whp with 300tq is not all that difficult or cost prohibitive anymore. Why would you spend $30k on an engine to give you less? Just for the revvs?


I have a friend that has a Ferrari F430. He took me for a ride and I took him for a ride in my car down the same road. We both said the same thing...the V8 FD 'feels' faster because of the torque. It was actually pretty interesting the way the F430 felt, really started to take off around 7000rpm. That car's most impressive feature (aside from the sounds it makes) is its brakes! HOLY mother!

Some people don't like the 'immediate' torque feel of the larger displacement V8, and I can see that point of view, but one thing that does is make the car a little easier to drive fast because the torque curve is so broad.

Ls1 is a great way to go. Light tons of power revs to 7K and cheap.

ive actually been thinkin of kickin it old school.. and dropping an old 350 small block in a fc shell

anyone consider Volvos V8? lol me and my volvos.

Agreed. If anyone wants more rpm just put a solid roller cam and a ported intake in it and the power band can extend to 7500+ ... without sacrificing the broad torque curve. The LS motors are an awesome powerplant from stock to wildly stroked and modified.

Would have to be anything LSx.. due to cost tho I just stuffed an LT1 in mine. ;) It's a freakin' hoot.
