currently running a silver top zetec 1.8
thinking about fitting a blacktop 2.0
now the car has passed its sva.

can i use the same set up ie mt75 box/ r1 carbs/ megajolt ecu.

I beleive so but be aware the water pump drives of the back of the belt so you need an aditional idler pulley.

I would guess Re tune the megajolt and the carbs.

sump/pickup and manifolds would swap over. Just the alternator and waterpump idler to sort.

Some sensors are differant / have differant threads.

Cam cover is a bit taller by the looks of it.

Any reason for not getting a good used silvertop ?

ps dont have a spare Mt75 Fs do you ?

cheers

Yes, with the following suggestions...

Fuelling will probably be out as the heads and pistons differ between the 2 versions.

Put your existing thermostat housing on the blacktop (it's a straight swap but the blacktop housing has different sensor threads)

Take the flywheel and clutch off you silvertop as you know it works.

Sump - I shortened my own blacktop sump / pickup - it's an easy job and means that you could sell your current shortened silvertop sump/pickup to offset the cost.

Well worth doing as the silvertop has hyd followers and the blacktop has solid/shimmed, i found that high revs the silvertop hyd followers leak and you loose power for a bit till they fill up again. This happened on both of my silvertops. (no problems with blacktop thow).

sorry wasa i don't have a spare mt75
there doesnt seem to be that many silver tops around now but lots of black tops,

still looking into the swap.
my silver one is smoking and has low oil presure.

thanks for the info everyone.
