1.3, 1.4 inlet etc

[loggyboy]

will the twin 40s curently fitted to my 1.3sr fit an 1.4? (and if so which 1.4s?)

[Adam]

The inlet will bolt on yeah, but the ports are all wrong.
Assuming that is, they currently have an inlet to suit a 1300 head.

[loggyboy]

Will this have a hugely detrimental effect on performance?
Is what you say of all 1.4 heads (carb, spi and MPi?)

[tom_beverley]

A SRi head would probably be the closest match and give the least turbulance into the head if you must use a 1.4 head

SR's and SPi have square ports whereas the SRi have round ports.

[Stuart]

if tis anything but the sri then fit the 1.3 head too for a nice gain in go with the carbs.

if its an SRI then sell the inlet and buy a 1.4/1.6 mpi inlet for it.

[loggyboy]

Im selling the carbs/inlet etc and retaining the head so thats not an option. A a possible buyer has a 1.4sr and wondered if theyd suit.

[Stuart]

nope.... unless the person fitting them dosent care about feck all gains

[loggyboy]

thats a nope theres little in it or nope they wont fit well?

[Adam]

They will bolt right on.
But the ports are completely wrong, so air flow will be ****e.

They will "work" thol.
