Frankenstein motor

Hi everyone. We are working on a 91 CRX si. it has a bunk D16Z6 (Vtec) in it and I'm looking to put some parts together to replace it. I have a B20B4 CR-V block i got for $65 and a B18 P72 Vtec head that iv had for some time now. I'm thinking about putting the two together for our car. would I use the engine swap points system for the B20 and take the 100 points for a cylinder head change? Its a nonVtec block being mated to a Vtec head. Thanks

Don't forget the 50 points for the intake

[zack_280]

Wouldn't the head swap include the intake and exhaust that go with the head being swapped on?  If not, the OP may be better off just claiming the swap and finding a "VTEC" block.

thanks guys! I was hopping to use the B20 block just because we have it and its in great shape. I thought the manifolds would be part of the head swap.

Short answer: No

 

Long answer, you "pay" for the swap and get a complete new powerplant, anything that you want back from the discarded engine is now points as if it is a foreign component, otherwise, if one wants to get the intake for free they are welcome to run the CRV intake.

Opinions on this should be interesting. 

 

How many horespower do these franken motor Honda’s make?   They are remarkably fast.   Not like Ludicrously fast or anything

Ray has already ruled.

Were not sure on power yet. that B20 offers more torque gain than HP.  Were not 100% sure thats the way we want to go. that set up isn't the most reliable set up in the world but its super cool and we already have the parts.

He did.  But this is the Internet. And surely someone’s head is exploding right now as they work up an essay to correct his evil ways

In a 1900lb Crx or Civic hatch they are blindingly fast, as in I think 2nd fastest lap out of 84 cars at Road Atlanta this year...

 

195+ hp at the wheels, so pushing over 100hp per liter at the crank...

He is swapping in a “complete” b20 engine (50pts), then putting on a b18 head (100 pts). I assume all parts need to be b20 except the head and everything inside the head. So he he would pay for a non-Oe intake if and only if he isn’t using a b20 intake. Correct?

[ironworks]

so what about the b18 cams? would we than have to add points for b18 cams since we can't use the b20 cams?

Why would you put it in one that weighs that much

You swap the head and get the stock b18 cams/valvetrain

Sweet!

[ironworks]

if we go with this set up were probably going to wire the vtec to a switch so we can leave it off for engine longevity. 

[Black Magic]

Although you have the block, if you want to be competitive you have tied up a lot of points in the motor. The rules tend to fit better with stock motors swapped in when budgeting your points.

Thanks for the input! I think we would much rather use the points to build for longevity then chassis then power. The D16Z6 that is in the car (since I bout it) isn't the stock engine. but at least its an engine using the same head for that engine.

and transmission

[rod rammage]

Would there be  points to claim if he uses the CRV intake manifold? (Or do the intakes from the B20 not fit the B18 head that he wants to use?)

If i swap the heads on a mustang 5.0, do I get the cam and valvetrain upgrades free too? 100 pts total?

  Logic  would say that you get the rockers valve springs and pushrods  as you your Cam will work.

 In Honda world, you would deprive the head swap of the  stock internal pieces  to the point of having an incomplete   assembly ?

 

 This isn't an engine swap where we are contesting cast iron versus exhaust header, the Honda would be getting a stock street camshaft

If you can figure out how to put Mod Motor heads on a Windsor, I think yes you also get the cam(s) free.

I think your interpretation is logical, but if that's the intent I don't think the rules are written that way.

 

Sorry if pointing out these areas that need clarification irks you.
