The VFR1200 engine puts out 170 hp and 95 lb ft of torque with a dual clutch transmission. Is an engine swap possible?

Sure it is so as long you have the necessary fabrication skills/funds needed to do the swap right.

 

X2. Anything is possible. If you have money.

 

anything is possible... as long as you got the dough to back it up.

 

id love to put a bike engine in the fit i wouldnt care if it made it slower i want a car to rev to 16000 rpm!

 

i just wouldnt like to push it out of all the parking spaces - no reverse on a bike

 

retarded thread is retarded

 

Tell us how you really feel!

But I kinda agree with that sentiment..

Not that bike engines in small cars haven't worked out in the past... like GSXR/Hayabusa powered Smart cars, but this would be a very technical and expensive endeavor, and the power band of the 1200cc would not really be a whole lot of fun in a street car, the transmission was not designed for a vehicle that weighs that much either. It is a DCT constant mesh for a ~550lb GVW bike..



So while we are on the subject of outlandish but potentially cool engine swaps.. as a blend of this and the small block V8 Fit thread I give you this:


2.8L V8 producing >450HP @ 10,500rpm. Here is a dyno video in a Caterham 7:

If your little heart desires, they do exist and have been tried and true for a couple years now, like in the Radical SR8 they keep flogging around the Nordschleife.

The potential for >500HP at the flywheel in a ~200lb package.

For the money involved to take a brand new engine from a brand new $17,000 bike or to do a small block V8 swap into a GD/GE, this is the route I would go!

But still at the very least I can say it would be prohibitively involved and expensive for those without the skills and most of the tools required to pull it off.

Edit: Something I would like to point out is that even though each turbo is getting 4cylinders, for a total of 1.3x liter displacement, the smallest turbos they will use are GT28s or GT30s vs the GT25s you see coming in GD turbo kits.

This is significant because they will rev this engine to 10.5k vs our 7k, but it starts boosting (which you can see/hear in the dyno video) well before that on LESS exhaust gas volume than our L15As put out at the same rpm and still flows enough for the 470cfm (assuming 90%VE) that just one bank of the Busa V8 puts out at 10k redline.

For comparison our Fits flow only ~350cfm @ 7k redline (assuming 90% VE), but puts out more exhaust gas at a given rpm because our engine has an extra 100cc displacement/rev. Which would make for a mean torque curve down low with way more top end potential then a GT25 at lower required boost on the same size turbine housing.

Or you could make the bigger GT28R spool as fast or quicker than a GT25R (making considerably more torque), run the same boost on a smaller turbine housing and still have better top end, until you up the boost to a point that requires enough drive pressure to take you out of the 60% compressor efficiency islands.

What I am getting at is some of you turbo GD guys with an AEM FIC or comparable should try swapping out the GT25 compressor wheel and housing that came with your turbo kits, and mate a GT28R compressor wheel and housing onto the GT25 CHRA and turbine wheel/housing combo. It is a bolt on affair!

This compressor upgrade would provide the same power at less boost which is easier on you fuel pump and injectors or more power at same boost with any given turbine wheel/housing combo attached at the other end..

 

Haha... Gold-Wing engine it is. 1.8L flat 6.

Wait... thats only 118 HP.

I haven't heard 170 for the VFR; more like 140-145.

What would be fun is that it's a V4, and designed to mount longitudinally, and outputs to a shaft. You could run it to the rear tires, and have a badass RWD Fit that revs to 10,000. Has anyone ever made a V4 for a car?

 

Lancia made v4's back in the 50's 60's maybe even later than that

 

My friend's 17' runabout has a 3.0L V4, sounds mean and it'll do 45mph with people and gear!

 

haha then id be just like my old 240!
