good day to you all, i see that gav dimond has a gt40 for sale , its prtty cheap to ,what is the differance between that and a t4 ,apart from thewastegate ?

and cams, well i am a bit confused my engine has just come back from richard longman and he said that it has a bd12 inlet cam in but when i looked them up in the burton power book it has less lift than a standard cam?? the thing is that it must do something differnt other wise what would be the point of selling it??
cheers gary

im no expert but... the bd12 inlet probably has more duration... so the valve is open for longer

garyrs

ok cheers, i also have an engine with a bd 10 , wich is 8.6 and 264 duration , is the bd 10 a better cam??
no one got any thing to say about the turbos ???

GT40 is much bigger than an RS500 T4.

Good for hundreds more bhp than the T4, over 700, depending on exact spec.

garyrs

thank you stavros, so its a bargin for 500 quid then, cheers

Stavros

Fairly cheap for what it is, usually about a grand new from america, so twice that from ripoff britain.

Do you need a 700bhp turbo tho? If your not putting out well over 600bhp youd be mad to use it, even a GT35 on a Cossie is bad enough.

garyrs

no im not gonna use it on the cossie, i am lookin for a big turbo for my e30 bmw, think this may well fit the bill , cheers ,gary
