I am driving a e30 316i manual

Can the sifus here advise if it will improve acceleration if I swap the exhaust (mid to end portion) with that of a e30 320?

An exhaust shop boss say can improve...

TIA

for 316 u have to change ur rear diff ..to have better acceleration ,
changing to another bigger exhaust will just underpower ur car ..not enough air going out .

bro it is stated 316? aiseh, improve speed should be 2.5 atleast. Get a halfcut, don waste yer time on exhaust or diff. seriously. the exhaust boss said to you because he only want your business mah.

Just say you still want to spend.
Okay here are the breakdown
Diff - +-500 (if you want R&D should be atleast 3 sets of diff)
Exhaust syetem -+ 800 (you ended up go back and forth to make it your perfection... again the boss say "if you dont like the setting i can make more pick-up")
Then after that, another boss said change fuel regulator/injector/silicon copper plug wire set/spark plug or another "brother accessories shop" suggestion. +- 1k

Total spend aroun +- 2.3k already... still 316.
Then when you drive - next to you is 2.0 or 1.8 you think you can overtake them?.

Source for halfcut with geran, it only cost you 2k - 3k for 2.0 or 2.5 motronic 6 pot engine. then you can fly!

Cheers!

I in Singapore - so engine swap is illegal and maybe swap to M401.8L is not noticeable in annual inspection - so halfcut cannot leh.. Sad

aiseh.. now i know. Wokey, change diff then. BUT sourcing diff for 316 can find meh in singapore? annual checking in singapore tak buleh buat apa. they will notice also. UNLESS, rebore to 1.8. Buy engine kosong, use back your existing block but plant in 1.8 pistons, camshaft etc. You'll have 1.6 block inside 1.8 woohhooo. Then when they do the checking, everything seems to be normal. Tapi if they use diagnose engine capacity you mesti kena...mmmm good luck.

Yes, try google... it might helps. Cheers!

to be honest, its not worth to play the 316 at all. My advice to you is to do up the suspension and the chassis, bodykit blah blah....u'll be happier. Smile
