A B230 will make 200bhp fairly easily - a quick balance to make it rev to 7000rpm, a naughty cam, and a set of 45s...and a decent exhaust.

He's talking about the B230K with the pierburg carb, which will drop straight into a 360 as Dai says, but not a 340 due to the differing transmissions etc.

However the B230K is not the best 2.3 engine to start with as it's the 'Heron Head' engne and as such there are no cams available for them.

True not the best of 2.3 engines but if he had a 360 then I'll still go fot the foc engine.

Good point chaps...I forgot that he mentioned a carb, hence we were talking about a B230K

Really? I was under the impression that they take normal OHC redblock cams...?

cheers

I did not know that the heron heead would not take the normal cams either - but I've never bothered doing anything with one as I hate EGR and there is another point - na turn it into a washing machine.

................ok erm...... i would have the transmision also i get the whole car with the 5 speed box will the 740 box fit (bolt on)?


foggy do you have 250hp on standard drivetran?

same i thought all redblock cams fitted all redblock it says so on the volvo performance parts site as you cam buy the cams there

No, the 740 has a standard gearbox mated with the engine, the 300 has a transaxle design with the gearbox over the rear wheels attached to the engine via a prop shaft. It could be made to fit but would mean serious mods and almost certainly isn't worth it. You'd also lose the even weight distrubution which is one of the 300's strongest points.

mmmhhh
ok that was my hope of a cheap conversion oh well i guess i could have a look through the scrappys here for a 1.7 turbo or 2.0 i hope they had them here

Well I'm only guessing, but as the Heron engine is an interference engine with its normal cam I'm ASSuming that if you were to put a hotter cam like a 'K', 'H' or 'VX' in there you'd smash the valves straight away.

they technically fit , altho rupert is right about the interference fit .

B230k has an X cam fitted ? about 10mm lift ? as a rule of thumb most engines have an extra 1mm of lift in them before you need to check .

Anyway if youre serious about it , youd machine the pistons back .

having got some b230k pistons , those valve pockets wouldnt have to be done by a machinist either .

Are you connected to Mr James' dreams thru' the powers of telepathy?

The competition Gp A trans stuff doesn't handle anywhere near 250hp.
IMHO it is the achilles heal of v300 and big power- hack the tunnel Ford type 9 and baby Atlas out back.PIA to do- but do it once and it's fit and forget

beg to differ about a type 9 , a cossie box would be better (or an Mt75), hmm baby atlas might not be as strong as a volvo dana 30 either altho all together lots more ratios and parts .

the front gearbox live axle 360 has been done before .

the only way to increase the power handling capability is

a) porsche transaxle
b) alfa transaxle
c) make your own

and get rid of the torque tube at the same time .

ive got an idea about a daf somewhere in my head .

Quoted type 9 due to ease of parts and relative cheapness- M45 s/c c/r gear kit a grand plus delivery then has to be built.
type 9 with quaiffe pro kit and fresh rebuild £1200 to the door.

Have heard the Volvo axles are strong but again lack of parts and cost would rule out to me- Atlas axle can take $hit load of power thru' it and plentiful.
Got one in the shed with a 4.6 if you're intrested-plus Capri special axles still avail for relatively little money-tighten the plates and you're laughing.

Don't get me wrong I like Volvo stuff but with a pitifil 137 @ wheels we've been thru the shaft snapping scenario-replace with shortened Cossie ones.
then you find the next weakest link and the diffs just disintergrate-overcome thet and the fancy HOR motorsport g/box lunches itself.
Bearing this in mind you must forgive me when I raise an eyebrow at figures like 200+hp thru' stock trans.
good luck with your project.

Yes, can't claim 250bhp quite yet Somewhere in that ballpark is my goal, but I'm going to get the turbo motor bedded in first before I start getting all excited about additional power. I'm planning to keep it down to that sort of level to preserve the drivetrain...har har!

Rally cars appear to be very hard on their drivetrains. John Lane (500+bhp turbo PRV V6 262 rally car) is constantly telling people on Tbricks to throw away their 'jelly' M46s, since he made a mess of one with just 140bhp. Another guy with a street car is putting just shy of 400lbft of torque through his, and has been for years...and he doesn't baby it!

Two 300s which definitely are making relatively big power are Huskyracer's 340 Turbo (~210bhp on a trusted dyno), and Kev Strong's 360 turbo (claimed 315bhp). Kev's car is running a B230ET bored to 2.5 with extensive headwork, plus balanced to rev out to ~7500rpm...and fuel system add-ons to match. Whether or not that's a formula for 315bhp is a matter for some debate, but especially with that extra RPM, it's believable.

Given that the M4x series in front-mount guise are known to reliably hold at least 250lbft in road use, there has to be something in the 'usage' when rally cars seem to commonly trash their boxes with only around 2/3rds of that torque. We've seen the same pattern on Tbricks, although us UK guys have always put that down to the yanks not being able to drive properly

cheers

James

Tbh the yanks prolly abuse the box as much as we do rallying... they arn't used to a shift stick as well as a central steering stick

Rallying does seem to be the most abusive thing you can do to a car, ask Fake, she's needing a bit of work now, and I only do the small stuff.
