Robin hood s7 triumph based

[Tgill]

Hi all,

I have an early s7 with the triumph spitfire 1500 engine. I have been offered a mk2 mazda mx5 1.8 engine and gearbox. Would this fit? 

Thanks

You should be able to make it fit but it certainly won't be a straight swap.  I don't know of anyone who has tried to put an MX5 engine in an S7 but somebody may well have done.

Thanks @Foz

What would be considered an easier swap out of interest?

[Foz]

Good question !  I think most later S7s had Ford pinto engines & type 9 gearboxes but I don't know that much about the S7 so I'm not sure how different the later models were.

Maybe there's some else on here who can remember and offer some advise.

I owned a Triumph S7 with a Dolomite Sprint engine and yes it is possible to change the engine but you would be giving yourself an incredible amount of work. Engine and gearbox would have to changed, mountings fabricated, totally rewired, new propshaft fabricate and that is without considering whether the rear axle , suspension and brakes could handle any extra power. my suggestion is to enjoy the car with the spitfire engine but look out for a more modern base ( 2B or 3a or Sierra based S7) to do any conversions

Thanks @alantoon
