Big bore throttle bodies and 3.5 injectors

[k10]

Can I have informed opinions on M30 3.5 throttle bodies and injectors, do they fit into a M20 2.5 ?
is it worth doing and power gains?
I'm looking for more beans on a budget, so don't want to shell out £180 on a zone big bore throttle body, will others fit?
Also has anyone ever put 3.5 injectors in an M20, do they fit and can the block handle the extra fuel delivery etc...
I expect it's all been asked before, but a quick search revealled nothing.
Cheers

Leave the stock injectors in place dude, the M30 items will simply drwon the car with fuel and cost you £Â£ and power, the ECU has no way of knowing the injectros flow 20% more gas so the inj_open time will remain the same regardless, unless you chip it to suit ( more dead £Â£Ã‚£ )

there is NO need to add bigger inj on a stock M20B25( or M50 for that matter ) bigger power 2.7s can run lean as the inj max out but you need to be puching 210+ HP for that o be an issue.

Re the BBTB, its a great modification, and if you email the source ( Alpina527<at>AOL.com ) I think the exchange price will be more agreeable ??

Sorry slightly off topic

Ant what sort of BHP would an engine need to push for the M30 injectors lean out?

What engine ??

Look up the flowrate for the given Inj @ given fuel pressure, there are links in the FI section

Ant, does the BBTB work well with an ( A-Tech ) chipped M20B25 ? I'm thinking of this for my next mod.
