Ooer mate, the highest BHP we had was the RS2000, was overbored to a 2.15 running a 50% NO2 system, it peaked at about 300BHP, but there was extensive work done to the chassis, and backend to deliver that to the wheels through a MT75 square cut box. Could spin the backend in 3rd at 90, that was fun I'll tell you, fairly gave the Porche's a scare, funny seeing a snotty nosed chap in his 911 turbo eat his hat when an L reg MK1 Escort blows his wheels off!!!

Take it your going down the 5 link back axle road with slipper springs? Have fun with that one. Well done in getting a MK1 shell that is good enough too!! Not easy to get now.

Hope the Induction kit work is fruitful Yodi

Hello Chaps

Just a quick question on the subject of getting more power from a 325i

325i = 170 bhp

525i = 192 bhp

Is the difference just a chip?

If so would a 325i owner just be able to get the 5 series chip from a scrapyard and get 22 bhp for very little money?

My 12 valve M20 engine is listed as 192 bhp, whereas the same engine in the 3 series is 170 bhp.

There may be more to it, but I've often wondered about the difference, and if it is just something thats plug in, with the amount of E34s in scrapyards, it would be a cheap way to get 22 bhp.

As for e34's early 520's and 525's had the 12 valve head and 170 bhp and later cars post G/H had the 24 valve 192 bhp engine which was the same engine as the e36 320 and 325 models. Hope this clears this one up, so in other words a chip will not get you 20 extra BHP, but you can always fit a later engine and this will do the job, however with much more work.

So couldnt you just put the 24 valve head on the 325? Ok maybe not that simple but surely would be easier than taking the whole engine out.

it would come down to wether u could time it up correctly or not ! the easy way to find out would be to fone a dealer and ask what the difference is on the pulleys !  if they r the same it should work !!??

  if u can fit the 24 valve timing belt/chain whatever it uses !!
