as the turbo is one the rear of the 4b11 and hangs on the front of the the 4g63, this wouldn't be a straight forward swap, sorry, but I'd say stupid question, imo the 4b11t is the better engine.....waits for the flames.........

It's an improvement in power potential, that's for sure. Time will tell the rest.

Whats the point of doing this swap? It would be an excercise in frustration for no real difference in power making potential.

no flames. I would put the 4B11T in the CT9A, only reason is; simply because it is lighter and better weight distribution since the turbo is on the other side, so closer to the CG of the car.. If you want to be real serious building a strictly race car. ANd you lost all the weight already.
Thats all.
No other reason. The same reason i wouldn't put the 4G63T in the X , because it is the opposite.

Besides the fact the engine swap is really not worth the hassle at all, in both case.

I know you guys push the limits down in PR but wow what kind of failures occurred to go through 3 engines and now on to the 4th?

Any insight on what is/was happening and how to avoid it?

As for swapping a a 4B11 with a 4G63 I think you can do great with either unless you are pushing the engine past 800 crank HP and want something that has had more development time. For the VAST majority of people that are staying under 600 crank HP I think the 4B11 is the much easier route although both engines have proven their performance potential.

Yup. Back in the mid-late 90's, Honda guys would blow up their engines by just doing bolt-on mods. It would change the VE of the engines enough that they ran lean and kaboom, there went the head gaskets, etc.
