How do you draw that conclusion????

It's not weak. Far from it. It is in fact a lot stronger and far better braced than a Griff or Chimaera. There is also the roll cage which is very substantial. The problem is the Cerbera chassis is wrapped around the AJP engine which is extremely compact in itself. The space for the bellhousing is incredibly small which is where the problems come. If you get a LS1 bellhousing to fit, the engine is too low or fouls the front chassis. You can get different bellhousing that have a reverse starter motor but then there is no room for them either. It has taken a lot of time and effort and a bit of lateral thinking to solve it.

There is also the small matter of routing the manifolds as well and other bits. As I've said before there is more to it than simply dropping the lump in place.

The only reason I'm doing a body off is because the car has chassis rot in the wrong places.

I draw that conclusion from your comments. It's a tight fit:

For the Cerb chassis to be stronger the chassis tubes need to be wider apart therefore you have at least as much room as a Griff. You now say that the space for the bellhousing is the tight area so surely the T56 would have been easier? -

The T56 has the narrowist bellhousing and runs a centre realise bearing.It also has the same output spline as the T5.


As an aside the manifolds look to be the trickiest part. J

Not sure that I agree with the stronger chassis needs wider apart transmission tunnel but if that is your basis for the weak chassis then OK, I understand where you are coming from. Don't agree with it though. The rigidity and strength comes from bracing more than anything. Look at the two chassis and the difference is quite noticeable.

Bracing helps with rigidity (a lot) but adds next to nothing to the strength. Out of interest can you post the cross sectional dimensions of the transmittion tunnels of the two cars. I could then tell you the relative strengths. J
