1915 turbo, help
 

Hello,
New here, I need some advice if anyone can help.
I have a 1915 turbo,older model engine I dont know the year its in a sandrail. I am rebuilding it now but dont know whether to stroke it to 2276 or keep it bulletproof at 1915. Ive been told its way too much $$ to turbo a 2276 and to keep it 1915turbo and possibly add a 50 shot of nitrous would be just as powerful. I would like to go the least expensive route, my budget is limited. Any advice would greatly be apprecieated.

Thank you in advance
Robert
