v8 4.3 into is250

Well - Lexus - IS-F. OK it's a 5 litre V8.

What's the point of trying to mod a 250 - you'd need to update the entire drive train, brakes, suspension, etc.

A whole lot easier and better to just trade in the 250 for an F.

A more sensible/easier swap would be the 3.5 2GR engine. More powerful than the V8 to boot

I have seen IS250 to 4L 1UZ-FE swap from Lexus LS400 and typical LS1/3 swaps (tell me what car didn't have LS swap?). After all IS-F mule was based on variation of 2UZ/3UZ versions, later UR1 4.6L before development of UR2 was completed. In term of 2GR and 3GR - that would obviously be easiest, but I guess the question is because of V8 - which has a charm of it's own and V6 cannot provide that.

That said - all engine swaps are possible and IS250 can certainly "fit" V8 engine. From the practical point of view - before you finish the swap you will certainly spend more money than IS-F is worth which kind of defeats the purpose. Well except of maybe having fun project.
