Intake manifold m50b25-->m52b28

[Young Thrash Driver 1020]

Just trying to clear up a wee argument here...

Will the intake manifold from an M50B25 fit on an M52B28? Or will it need modification

2ndly, once the manifold is on there, what happens? I reckon the 2.8 will be have more power, where the other guy contends there will be a minute gain way up the top but all low end torque will vanish

Just of note. If you do decide to do this make sure the manifolds all sealed up well. Ive read of some of the guys in the states with various leaks from not sealing up properly and spent hours trying to find exactly why their motor was not performing right.

Google for plenty of views - in particular from the UK - of it being a good idea, in particular with a bigger throttle body. Then again, there are other opinions that you lose torque low down. Sort of depends what you want.

3pedals who posts here is adamant it is a crap idea and you are better getting M3 headers for a power gain (through the rev range).

I've googled it before and found dynos that suggest that:

- you do lose torque below say 4000rpm - quite a bit

- you do gain power above that

- the power holds on longer

- it works better with other complementary mods (eg headers/exhaust/throttle body)

It's sort of bolt on, but not really.

I was hoping there was a thread like this buried out there somewhere

Cheers, that clears things up

Conclusion seems to be: it'll work well enough by itself but other mods will help

: M3 bits a better but more $$ option

Not intending to do this, we were just arguing for the sake of it
