Big bore throttle body

Post by alec.m »

I`m getting tempted to do the conversion but can`t find out which throttle body you have to use. I`ve looked in the knowledge base but "Fixer" bought a kit which included all the parts. I`m going to buy all the bits as I find them on ebay unless someone knows of a reasonably priced kit with all the parts included.

The fitting requires an "interface" which allows the existing throttle to work with the big bore throttle body... it also then connects correctly to the M50 intake manifold...send a message to:- alpina527@aol.com He makes up the necessary interface etc...and his price is reasonable for the full kit too...
Ask him to email you the pics etc...:wink:

Thanks, II`ll do that. Seems a cheap way to get quite a few extra horses. I`ve seen the adapter/interface plates on ebay on and off over the years.

Update:- Had a word with alpina and it doesn`t work with the 2.8 TU Engine so that leaves me with plenty of money to invest in Southernboys new cupholder!
