Plonking a 4.5 in the 4.0 - issues?

[China100]

Hi Guys,

I am at the point of putting a new engine in my Chim. I got this as a project without the engine but was standard 4.00

So as I need an engine - am I better just getting a 4.5 in there? I do have some decent 4.00 heads??

if I went with the 4.5 - am i looking at many issues? insurance, further upgrades like brakes etc??

I would welcome your thoughts ......

Hi guys

Some great comments and very thought provoking... would be a shone to go down the 4.0 let standard route as I have to opportunity to do something different. The car it's self was a project - off the road for 8 years, no engine and just a wreck. Now chassis rewrorked and looks great - new wish bones, bushes, refurbed T5 and Diff.. so it s getting there - but the point being at 73k and no engine/service history the car once done will only really hold the value for myself. I don't want to go to mad .. but there great cars and have no desire to get shot...

So back to it... the heads are the 10 bolt version. So general thoughts go for the gems 4.6. New cam, my heads.. using the original fuel system/injection - would this be an alternate ECU to the standard 4.0 I have already?

Fortunately at mid 30's I should be ok on the insurance front just didn't know how it would be classed.
