thanks for the comments lads!
i was thinking of cable tie stitching but tbh the fibre glass had blown out so i still would have had to fibreglass/fill and paint it.
ive just ordered an aem piggy back ecu.hopefully get it in and mapped within the next month,so should be running about 200bhp,with injector sizes being my only limiting factor.
bigger injectors next year,stronger diff,bigger brakes and hopefully 250bhp,btw this thing weighs less than a ford fiesta.should be fun!!
