Can the C35 be bored?

LOL I really didn't know if it was a serious question or if people were adding to the sarcasm. My response was serious in case anyone really didn't get it. Carry on

Science of Speed has a stroker kit for the NSX to go up to 3.8 liters.
That kit is 95mm bore X 88mm stroke

So, if the piston spacing is the same as the NSX like Matt says, then we should be able to get 95mm bore too. C35 has a 91 mm stroke so that calculates to 3870.167 Cubic Centimeters or 236.080 cubic inches.

So, who will be the first to stick 95mm pistons in their Legend?

I did look into it very briefly when i was contemplating a 3.5L swap or to stick with a 3.2L (i stuck with the 3.2L and did major servicing)

Pricing would be astronomically high in G2 Legend terms (well that's relative since most of my customers wouldn't be bothered with that )

the custom sleeves won't be cheap the pistons alone will set you 700-900$
If you'd need a custom crank to stroke it - $1250-2000, Connecting rods for the custom crank $600-800

Those prices would be US prices for europe add 50-70%

Then you'd also run in to intake problems since a 3.2L IM is not designed for 3.9L so factor those costs in as well,

I think your getting my point it ain't cheap although personally i say it's partially worth it.

But factory cost in to a sort of chart of ultimate or worth while mods it isn't going to rank above a RWD or AWD conversion.

I never said it was going to be cheap. Sleeves and pistons will set you back more than $2000. Most people would say an All Motor build will cost more than F/I and net you less power. I agree with that. But there are plenty of pros, and with F/I there are plenty of cons.

Also, you touched on stroking in your post. (that sounded dirty ) I never mentioned stroking the Legend but was making a comparison to the NSX stroker kit from SOS. I think the OEM stroke of 91mm on the C35 is plenty and piston speeds are already high enough. I'm skeptical that the C35 could even be stroked at all. I think a bore and stoke of 93-95mm X 91mm sounds great and would make a very powerful engine without a stroker kit. No need to stroke unless you just want it square. Oversquare sounds fine to me.

You made a great point about the intake. Most people that do an All Motor build would add ITB's and a significant port and polish. That would be great and all but is more uncharted, expensive territory. Perhaps the NSX ITB's would fit? If I were to do this type of build, I would start out with a P&P and use a type II intake manifold. I think the type II IM may work.

Re-sleeving for the NSX block is around the 1500.00, and the NSX TB I know fits the G1 intake manifold it might fit the G2.
