Default Does anyone have info on swapping a cl-s v6 into a prelude??

Guys after seeing the accords with cl-s swaps, my prelude wants one lol

I'm mainly concerned with mounts....

My original thought was as follows, those guys are able to swap h22s no problem, right? So if they can also swap j series v6s, why can't I??

If anyone has some info, please post it up, in the meantime, I'm on the search for a cl or tl service manual for some dimensions.

Thanks

Isn't the accord V6 engine bay larger than the accord 4cyl engine bay?

I have been told that on the 5th gen accords (99 style) that your statement is right, but on the newer ones, they're the same. Honestly I have no concrete info. I was hoping someone knows of somebody who has done this before, I heard from one guy that he has seen it.

Either way 90% of the "info" that I have gotten so far has been hearsay.

Ok, so I was asking a rhetorical question. The 94-97 Accord V6 is 3" longer than the standard Accord and that extra 3" is in the engine bay. The subframe is also different on the V6 and they are not interchangeable because of the engine bay size difference.

The 98-02 Accords also have a larger engine bay when compared with their 4 cylinder counterparts. The firewall is pushed back on these, you can tell by looking at the master cylinder, it sits underneath the cowl on the V6 and it sticks out on the I4.

All preludes 92 and newer share the same engine bay dimensions with the 4 cylinder Accord of it's same year, so in other words, the V6 swap won't fit. The heads on the V6 are too tall and you'll have to modify your firewall in order to get it to fit.

This statement is incorrect because This would mean that a 99 prelude would fit a v6 because the 99 accord did.

And you can't say the v6 is to tall because its short then the i4 because the cylinders are not straight up and down but in a 60 degree v
