Personally Edd i wouldn't consider it without proper management. You wouldn't get reliability or results without imo.
I'm just saying if it was me. For the price you can get management nowadays.
Just my opinion but with cash being a little tight I would hold off on the conversion.
Get it up and running and finish any jobs that need doing. Then get it on the road and enjoy it. Get to some shows too. Once you have had some fun in it then get some money saved, get a spare engine to tinker with then when you are ready do the conversion take off the road again.
Having a fun car to drive is not all about big power figures. Some of the most fun cars have little revvy engines that you can thrash about in.
Usually with more power comes more reliability issues
^What he said. If it was a cheap homebrew bit of fun it would be different, but the car its going on is special so i'd say save up and do it properly eventually
A cheap turbo build will end in expensive tears....
Cheap, power, reliability. Sums every engine build up.
