Good evening fellow Rovers,
I've been thinking of porting my 2.25l as I have the engine apart. I have a 63 109 with a bog standard 2.25l. I've put a Rochester carb in it and that seems to help it breath a bit.
Has anyone had experience with a ported 2.25l?
Thanks!
Jordan

It was popular back in the 90's, LR manifold were known not to line up well with the openings

Good to know.
Does anyone know if it made a noticeable difference?

Re: Porting a 2.25l?
This may or may not shed some light. On my S2 I run a stock SU carb, and I have had a Rochester carb on it. There is a slight, but noticeable power reduction with the SU This would make me think that the porting is not the weak point of the intake system, but the carb itself. This would make me think that it wouldn't matter how much I opened the intake ports, I would not get any increase in power. There are likely some guys here who can offer other experiences.
The reason I continue to use the SU, despite it's lower power, is that the engine runs like a top through all it's power range, and on pretty well any side slopes, or hills.

Seems to be good and I've only come across the vapur lock once... so more work to do there.

Most US carbs work well on the road but not steep inclines. My brother had the Rochester on his 88 and nothing but problems offroad. I had the Solex which was fincky to get right, but never burped offroad

Re: Porting a 2.25l?
It's not vapour lock on slopes. It's the fuel in the float bowl spilling into the intake.
As you run a Rochester, with more power potential, my statement about the carb being the weak point might not be valid for you.
I said I have SU. This is from my (not always perfect) memory. It may be a Solex.

2.5 diesel camshaft really helps the 2.25 petrol motor.
