1.2-1.4sr how much and whats needed

[bigbened]

im going to buy a sr engine in the near future, just wanted to kbnow how much i should be paying, and what do i need to convert the 1.2 carb engene to the 1.4. am i right i will need the 1.4 exhaust system

[Jon_nova1]

the price depends on how good the engine is, for the conversion all you need is the 1.4 throttle cable, the piping for the autochoke and the module loom, which is just to wire the distributor and coil, the exhaust will flow better but isn't essential

[bigbened]

is that all i need lads, will all the coolent pipes match up and the rad, wont the down pipe not match up with the 1.2 system

[Jon_nova1]

no you just need the piping for the autochoke, the autochoke goes into the heater matrix pipes (the small ones to the little radiator in the car) using t-pieces, i had to cut mine a little but it went on ok :)

The 1.2 manifold/downpipe will fit the 1.4 engine.
But the 1.4 one is much better, but that will mean having to fit a 1.4 system too.

best bet would be a hybrid engine build before putting it in.1.4 botten 1.2 head and 1.3 inlet manafold with 32/34 carb.then GTE cam. should match a GTE there abouts. most parts are easy to pickup.

[bigbened]

could i get that type performance just by putting twin 40s on it and a 1.4 ashley manifold and system

[Adam]

T40s on a 1.2, with manifold and system would probably give Sr power if not a bit more yeah.

[bigbened]

i mean on the 1.4 engine instead or aswell as doing what timmy said

[Jon_nova1]

i did that, can't remember what carb the 32/34 is but i put a 1.6 on mine, the only difference is mine was port polished and had a 1.4 cam, and it went very well, it was faster than a mates GTE, and kept up with a mates 1.4 injection with a lightened flywheel and lightened bottom end ;)

oh keeping in mind a few months later the you could get in the GTE, put it in first, put your foot to the floor and it'd accelerate like it was in fourth till it hit about 3000RPM, it inevitably got scrapped lol

[bigbened]

??? lol i didnt understand that

you raced a gte with a 1.4 with a 32/34 carb??
