Has any one done the 325 - 320 throttle body conversion?

Alrite, I got a 325 throttle body off ebay for 99p! I was jus wondering how much of a difference its gona make on its own untill I get a 325 exhaust

[e30-320i]

made a nice difference to mine throttle response is better and seemed to pull abit better although i fitted a zone chip at the same time so it was probably a combination of the 2
have you seen the guide in the articles section

Go for it. Made a worthy improvement to the 320i I had. When I sold it, someone came round in a 320i from the same year, and when he test drove my car, he was amazed at how much quicker it was - his had some fancy induction kit on it too!

wiked, the cars pretty quik as it is, it does my m8s 320 but i tweaked the head a bit while it was off but from what i can see the 325 parts go straight on with a little bit of modification so its a cheap way of gettin a bit more power! But im gona leave the chip till last i think i take the chip is worth the money and also did your fuel consumption rise?

i didn't really notice much change but i do most of my driving in town and only get about 24mpg anyway

Slightly better mpg.... certainly no worse. Make sure you get the correct bellows to fit your Idle Control Valve. Search the forums if your unsure. I swapped mine for the L shaped version.

i get about 40 - 50 miles on a tenna but it depends if im raggin it or not

mine are already the L shaped ones so hopefully it,l be alrite

Replacing the coil pack made a difference if thats any use to you mine was still the original part but when i changed it it was more responsive

I think I got my replacement bellows from GSF, so you should be ok with that one. I got a new gasket from the stealers. The replacement TB I used only had one port for the brake servo, where as my 320i had two hoses. I drilled out the secondary hole, and sealed the hose connector with silicone sealer. Worked a treat.

I know a lot of people don't rate boost valves, but after I did the throttle body conversion and put the car on a rolling road they tweaked it to match the increased air flow and now it runs even better, with a vast improvement to mpg and no emissions MOT failures. Do your valve clearances as well if they haven't been done recently.
