I'am putting 2 X 2" SU's on my l28. Has anyone here done this?

I've got all the linkages etc. but I'am interested in needle or seat changes.

Any ideas???

Give Dave Rebello a call in northern California. I don't have his phone number on hand, but you can get it from his website. He modifies early SUs to 50mm and may have the info you are looking for. I had a set done by him for my L28 and as I remember the needles were hand profiled.

I put a set on my last 240Z (L28 engine) off a 4.2 XJ6, and found the stock needles and seats from some parts carbs that I also got were pretty close, much better than the Jag set - they were from a Rover 2000TC, but cant remember the year, sorry - think they were the AAA profile.

That sounds good...ill suss it out...

did the 2" su's make the car drive much different?

Does rebello have a website ?

or a email address?

Datfreak,

Type in REBELLO RACING....it will take you to their site!

I had a pair on my 3.1 liter. They did improve the cars urge down the straights at Watkins Glen and Mosport. But NOTHING like what I got when I went to 45mm 3x2s. Not even close.

SU's are not a patch on triple side-draughts
