After owning a Z31, Z32 and a boosted S30, I've always considered myself a "Z" guy. The idea came to me one night - would it be possible to make an inline 12 using 2 RB blocks? Think of a monsterous, quad turboed, I12 tucked into G nose S30..

Well last night I was looking at the engine bay of the S and got to thinking the same thing. The F22C is a pretty compact little thing, so what would it take to fuse two F22Cs together to make a 4.4L I8?

Custom valve cover, cams, crank, intake, headers... Then tuning it to work... Those smarter than me please chime in...

 

you would need a completely new block...... that alone would cost SERIOUS money.... then you would have to have some serious brains to get everything working within the block, oil pressure, oil passages, tight clearances,

I say find another means of power........

 

This has to be a joke.

 

Rediculous.

 

Now wait just a damn minute. I realize many members on this forum are a little less than open minded and just accept the typical bolt ons but its been done and its effective. Thats not the purpose of me posting this. Is it cost effective? No. Am I looking to do it? No. So why ask? I am probing fore more information and trying to start a literate discussion as to how it COULD be accomplished were a big time tuner to ever do a project like this, whether it be practical or not.

Volkswagon uses two VR6s together to make the W12 - found in the Phaeton, Touareg, and W12 concept car.

Ford essentially used two Duratec V6s to make the V12 found in the Aston Martin DB7.

Inline 8s were used back in the day and it makes more sense to mate one inline config to anouther, albeit long, than two V configurations. Espcially with a capable motor like the 2JZ, or RB, imagine the engineering invovled and power potential attainable.

I suppose I need to be blunt like some other threads Ive seen: If you're an idiot or have nothing useful to post, then dont post in my thread. Not looking for opinions, I'm looking for technical input.

 

the question is why, of course you can do anything if you have the money.

the question for me is why, the sweet point of the motor is all the way up there, if you mate two of them together you will increase the mass and you can't spin the way it was before.

it sounds cool on paper but it's just not gonna work well enough.

i mean you can get a LS7 v8 that weight less than two f22 long block and it produce more torque and power out of the box and cost you the same if not cheaper

but as a s2k owner i must encourage you to do it

 

It might be possible. However, as iam7head stated, you will not be able to spin that much mass at 9,000 or even 8,000 RPM. Parts you would need:
- custom block
- custom head
- custom cams
- bigger oil pan, better oil pump
- bigger fuel pump
- run different size injectors to see what works and what duty cycle the injectors would run at in a motor configured like this
- 8 chamber intake plenum (BIG money to design properly)
- larger throttle body to provide air to 8 cylinders
- differently geared transmission depending on powerband of your frankenstein motor
- beefier clutch

The list goes on and on. I doubt it would be possible even if you were Bill Gates.

 

What about the guy that fused two Hayabusa motors to make a V8?

 

as far as inline goes 4 is good enough. Anymore have to goes to V configuration for better fitment and efficiency. So 2 F22C combine to make a V8 not a i8, b/c that just rediculous because it would be LONG!!!! hahhaha not compact and efficient.

Even the Bugatti Veyron with combining a 2 V8 into a W configuration. not a V16 configuration. hahhaha that is more scientific then working on something in the garage.

 

What do you think that'd do to weight distribution?

Why not just put an LS3 in.
