(T) new TB

yeah that the thread i followed one thing i changed was to cut the
p75 spacer in half just bellow the webber logo this is the right height and ID
while leaving enough gasket face to seal

just a random thought along these lines, if the 75 tb can be made to fit, can the 43mm bored out version of it be made to fit?

Do you not think 43mm would be too much?

Luke.

prob need to start thinking about moding the inlet manifold to get any benefit from it, can't see it making much difference over a 40mm one from tricker which will be easier to fit.. Are the 43mm ones from tricker too?

yes they are also trickers, i was thinking 43mm would be a bit much, may also affect the driveability, but there is a noticable difference between a 38mm and a 40mm one, so why shouldnt there be with a 43?, every mm counts, but wether the hassle of getting it to fit would be worth any minimal performance gain is another question.

would be an interesting experiment though

Well go stick some twin 45's or some 48mm throttle bodies on it.....then see how it drives.

You can go too big you know

Yeah, too big decreases flow efficiency, so the speed of the air entering the inlet is decreased. This is bad lol.

Luke.

well i have the punto 75 tb already... but i'm waiting to find an old 1108 TB just because i don't want to stop the car as i get the "thigs" prepared...

i hope i can try this soon...

for those who tryed this swap (standard tb for the punto 75 tb) is it realy noticed? there are gains in the performance?

Hell yeh! ! ! more of a boost then the 1.1 to 1.2 easy!

i've got to try it so! let's see if i can!

thx everybody! :P

i'm working on it! :P

cool Tis a messy job but worth it. I totaly stopped mine when I did it. also took the butterfly out and rounded off the bar that it goes into.
Dont look like youve got long left.

I've been reading all this threads about TBs and I still have a question. Will the ECU need some kind of remap, chip (or something) or will it just learn how to deal with the extra flow?

nope I ran mine for months with the standard ecu. run perfectly.

It will idle wrong for a little bit while it learns but not for very long, go for a 10min drive and it will have settled
