Injection to Carbs

[SteveP]

Evening chaps...

Right, well I've bought Rich's (Volvo360GLS) B230K and Weber 40's along with my K cam to go in my 360 which is injection. Just wondering if anyone knows what I'd need for this... I assume a FI > Carb fuel pressure regulator to step the fuel pressure down and the fuel pump blanking plate from the B200E fitted to the 230K. Can anyone else see any other complexities?

Also, are 40's big enough for such a capacity?

[Bilbo]

Depends on the chamber/jet sizes,what they came off etc,but with the right ones they'll be ok imo....I'd bang em on and get it running for a trip to the local RR man! You wouldbt want it running lean on cam or rich off cam etc....

That's most definitely the plan

Try and get some K+N's or similar rather than those sock thingies.
Caused many an underbonnet malady as Bilbo knows.

When I was looking at the same conversion I'd decided that 40s should be ok but they'd be at their limits. 45s would be much better, but obviously the price jump is quite substantial and may not justify the potential benefits.

for that engine 40's ought to be fine, the 230fk has the pretty appalling 631 head which makes it interference and has combustion chambers milled into the pistons iirc so I'd imagine the webers won't quite run out of puff reaching full potential. Should still see a nice 140 ish bhp from the engine though.

[SteveP]

Yeah, tis the 631 head - heard mixed things about it too... but with a K cam any redblock would surely be interference, so that really doesn't matter too much. Wasn't aware of the combustion chambers being like that though

[Jason B]

still, I know you got the engine seriously seriously cheeeep! as I know what price I turned it down at when I realised it was a 230fk (only on basis that I couldn't really justify driving that far for an engine which isn't compatible with my b230fb)

Not exactly sure on how much lift makes each 2.3l lump interference and tbh I don't really care either (H-cam on the way )

With the carb conversion once the fuel pump is sorted I would just try and scrounge some jets similar to a ford 2.3 as there is probably loads of info on them and the 8v's won't be hugely different.

[SteveP]

Yeah, it should work out ok then with the 40's it seems! So does anyone know what the stock carb fuel pump is like, is it like a B14 one in the side of the block? I assume I can use the blanking plate from my 360 and run the electric fuel pump still

[meintag]

I've the same plan, and I want to tune the carbs with a wideband lambda sensor. A LC1 from innovate motorsports + a RPM module is 'cheap' and effective.

For the pump, I'll run a continuous electric fuel pump from Carter in the US... High flow capacity and very low pressure. No FPR is needed. Tomorrow I look for a reference to you

40s will be fine IMO

Thanks meintag!

40 are a bit small on the b200, but it will be fine as it don't rev that much. But why a K cam? Get a h-cam

A friend of mine once told me that diffence between H and K is just few precent and racey idle. So i would go for the one which i can find easier and cheaper.

[Jason B]

Bit more torque etc, not hugely different but still better I would have bought the cheapest as well, but luckily I found an H with adjustable gear for less than I'd get a K for in the UK

[SteveP]

K cam because I already have one... and it was cheap
