    Hi

    I love my E36 318is - it looks great, drives great, it is in great condition - i was just wondering if there are any other peeps out there who have had one and have been able to eek out an extra 20-40 bhp on the cheap...

    - is it possible?
    - if so, what have you done and what did it cost?

    It would be interesting to know as i am really thinking about it. I know some would say to sell/part ex mine for a 323 or 328, but insurance etc is an issue

    Please any suggestions would be great

    Thanks

    any changes you make will have to go on the insurance anyways so it might actually work out better to upgrade anyway, otherwise you havnt really got much choice when it comes to budget tuning, 20 bhp is a lot to eek out of an engine on a low budget, what sort of money are you looking at throwing into the car and ill try and help out.

    well first up your not getting a supercharger for a few hundred quid, not that i would advise it on a 318 anyways, 2nd for lets say 300 quid your not really going to get any noticeable gains from your engine, my advice is to spend a bit of money on a really good service, a good service can usually bring back a few bhp from an engine, and then assuming you have any money left either get good brakes or suspension, that way you can go faster on the same engine plus there is less fear of spinning into an oncoming car.

    im guessing your quite young so give it time, get a few years ncb and then upgrade to a faster car, its been said before you could spend a couple of thousand on getting your car to 200bhp when the 328 is already 190 and for a few hundred will goto 220+ however if you really are keen i think you should go down the handling route so you can go faster on the stock engine, new suspension and brakes should come into your budget if you look hard enough, if you need help just ask

    It is possible to get quite a bit out of the M42/M44 but it's damn expensive.

    Supercharger will get you up to 200bhp but will cost you £1500-2000 DIY.

    Custom cams and a remap might get you 20-25bhp. Not going to be cheap!

    Actually thinking about it insurance on the 323 is quite cheap. Have you got any quotes? The 318is I always found expensive to insure compared to other E36's.

    I spent the best part of £1k messing with my 1999 318is and should imagine it was putting out just over 160bhp (based on what friends cars were putting out). It would stay with a 323 up to about 100mph. What you have to remember is the gearing also makes a big difference. From memory the big sixes are geared to do over 160mph whilst the 318is will bounce off the limiter in top.

    lose 200kg off your car in weight and you will have the same power to weight ratio as a 323, meaning you will be as quick as having 160-170 bhp in your engine, and it saves you loads of money too

    You need to weigh up the odds...

    Sell and replace the car with one with a larger engine or replace the engine in your car for a larger one.

    I opted for the latter but that is because my car was heavily modified and it would've actually cost me far more to sell the car and start all over again. The car had already been featured by two car magazines and there was only one lump that would do

    MOTORSPORT all the way
