I want as many horsepowers as its possible to get from a B200E with out turbo. So what should I do? I have read a little about porting, does anybody knows something about it? And since its injection, can its brain/chip (dont know the right word) be modified? Any ideas?

Why would you want to go the non-turbo route? These engines are ideally suited to forced induction and are relatively poorly designed for naturally aspirated performance...
Not saying it can't be done, just that its a very non-economic choice.

Can't tell you much about it, but afaik the cost/gain ratio for chiptuning is very bad.

Step 1. Decide what amount of horsepower you would like to get.

Step 2. Determine how you can reach it, to certain point NA tuning is cheaper and after that turbo is cheaper.

Step 3. If you did not install turbo, you will now, after 6 months

My latest tunging made my engine to 130hp/170nm, Megasquirt and K-cam, I still have problems with my fuel pressure so I could get bit more, not sure.

It will cost around 600 euros to get this power from b200e, changing only cam may not give as much gain to horsepower. Anyway cheap horsepower comes from used K-cam and if you can do all by yourself then head modding is rather cheap too.

Installing turbo charger would cost around same 600 euros, maybe bit more depending where to source parts etc.

Now all work is needed to do by yourself to get these prices, also needed to aquire used parts and not to buy first part that you find, usually it is not the cheapest one.

With turbo you can get 150-170hp without major mods, just increase fuel pressure, after that it comes risky with stock parts and ecu.

I bought a used B200ET for 150E. Came with new gasket sets, new plug wires and a new clutch. Also 3 boxes full of miscellanious parts like fuse holders, relays etc...no way that you can beat that sort of price. I think there is one for sale now in Holland for around 200E..still way cheap.

I'm going to ad a better flowing tubular manifold (needs to be custom so might as well take the effort and make a nice equal length unit), intercooler and modified megasquirt unit...that would be a total of around 600E for the complete engine and setup. Estimated horsepower around a safe 200whp mark..

NA tuning with volvo's would basically mean sourcing either a B230 variant or a 16V engine and transplanting that into the volvo.

So I am now thinking about turbo. How much power can the stock engine and diff and everything else stand?

What is the K-cam?

I would not turbo the stock engine when there are turbo engines out there that are ready to go..find one and transplant it into your volvo.

Those engines will hold up to 250bhp for the b230 and more for the B200.

K-cam is the hottest std cam that volvo produced..all nice and well, but still no revs..anything less then 7500rpm imho is boring when it comes to NA engines...better of buying a crx or something like that..

Isn't the H cam hotter than K? Came in from -79 to -80 B23E. Of course these are all std cams so nothing too "race." More aggressive cams can be found at:

but what about R-camshaft?

Good luck finding one. From what I know they are pretty rare.

but is this camshaft good?

If you want as much power as possible from a 200 engine, its easy: fit a turbo. Camshafts and all that sort of stuff cost you loads of money and dont' really help. If you fit another camshaft, larger feul injectors, stronger valve springs, gas filled valves, chiptune, enz enz you might get 40 bhp extra and you will be a 1000 euro's lighter. Fit a turbo that you buy for 100 euro's, make yourself a nice manifold with a weldingmachine and someone who knows what he's doing and you also got 40 bhp extra.

B230 will hold much more if you buy an engine with strong con rods. Weak 9mm rods were used from -85 to -89. (approx. but if you buy an angine from -93< 940 you should be safe.. ) and with weak rods the limit is ~250hp in normal turbo use, though one guy here has destroyed weak rods with ~140hp NA, though in endurance racing with 4000-6000 constant rpms for few hours. But in normal street use weaker rods will hold approximately up to 250hp with turbo.

Pre 85 engines, B17, 19, 21 and B23 have also strong rods, M-rods. (Well 70's models didn't have M-rods but from 80 to 85.) Those older engines also have forged crank shaft as the B2x0 series have forged crank only in Penta models.

Of course then there are aftermarket steel rods, for example from Sten Parner, which will hold as much as needed..

I have a friend running 300bhp at the wheels on a B230ET (the weakest version, with 9mm rods)! Get the right stock bottom end, and it's good for 500bhp (if you do it right).

K cam is the hottest commonly available one, but there are various hotter ones, including the H. The R camshaft is for a B18 or B20 OHV engine. No good for us. Unless you mean the 300 series R-Sport kit cam, which is a K.

CH....It very much depends on where you want to end up. If you're happy with 150bhp, go for it without the turbo. I have 140 bhp, and I'm far from finished with the tuning (wrong ignition setup, original exhaust, no electric fan...)

If you want 250bhp+ on the cheap, fit a turbo engine. It'll probably be faster for the same BHP too, as you'll have more torque per bhp.

If you want 250bhp+ NA, it is perfectly possible, but will cost a lot of money. You'll want a 16v head, hot cams, and a long-rod bottom end which will rev to ~10k (amoungst other things). You'll also need a low ratio diff, or you'll never get up to those higher revs in normal driving!
