Has anyone of you uses a B-series engine (either NA or Turbocharged) for serious track purpose? I would like to know the reliability and the strength of the engine at track....(any engine will do as long its a B (16A/16B/18C/20B))
 
I have been using a B16a motor for the past 2 years for track racing with little to no issues. I use a fully synthetic oil and do service's as per service manual. Only issues I've had are clutch but using a stronger issue now and over-heating due to seriously hot weather which a bigger radiator will fix. Motor has never been opened and has 245 000km on it, does not use oil I probably refill about 500ml in 10 000km.

My buddy has a B18C5 ITR and with Semi-slicks he experiences oil starvation under braking and cornering. We want to try fit a baffled sump to over come this but have not as yet. Maybe someone else has had similar issues and can comment on this?
 
B18C is reliable, it all depends of the track regulations of your class. If you run with a B18C where 2000 cc motors are allowed, you'll have a disadvantage against B20 motors. B20 motors can also be reliable but you'll need to tune it properly. I think the key is not to use pistons larger than 84.5 mm if you're going to run at autocross / circuit racing, if you will run on a 1/4 mile you can have your motor with bigger pistons and a after market crankshaft.
 
the shop i work at had a drag car 2.0L bseries 750whp 10.80 with full interior like 10 years ago and they never had any problems, they used the same engines for a few seasons, its all about building it right and keeping your temperatrues down.
 
are B16B a bad choice for track uses??
Have anyone of you come across the Spoon's B16B engine? its base on S2000's block design and a more polished head, stock and 10.000rpm no problem, i think there a vid of it here somewhere.....
 
why would the B16B be a bad choice for track racing? is that what you heard from rumors & hearsay? a well built B16B can last as long as how good you take care of it. for serious track racing you should have the oil pan replaced with a baffled unit, have the crankshaft, conrods & pistons balanced if you are planning on revving it past 9000 rpm all the time.
 
i use a b18c5 in my eg coupe(track car) an never have any problems i change oil an oil filter before every track day but i only go to track on bank holidays...only major prob i ever had was i burst my oil pan but thats cos i brought the car for a drive round where a live one nite to give one of my friends a spin in it an there was a rock in the road that i didn see an it hit the oil pan....other than that its jus normal wear an tear.

Click to expand...

No way, the B16B is a great motor, specially stroked to 1800 cc, against B20 the B16B has a disadvantage but you can even things up if you run in your class with the minimum weight! :naughty:

b16b, polished head, thin head gasket, B18C crankshaft, b16b oem pistons + rods, + TODA B camshafts + Toda valve train = :bow: hehehe
 
B16B is the most reliable and runs coolest because of it's Rod/Stroke ratio. Very little internal frictions compared to B18C and B20B, B16A is the next most reliable... But all Type R engines are reliable anyway.
 
well i personally thinks the 16B is a great engine, just that among those that participates usually uses B16A or 18C, there's seldom ppl uses B16B(from where i am), i don't know bout this but, i heard from my friend, its because of B16B's rarity that people scare of it got blow out and thus damage a classic engine(was it classic? or its vintage? nvm...) just what they mean was the B16B is such a engine that it should be kept in a museum rather than using it, huh?! WTF?!
Anyway, does boring it to 1800cc loses the B16B's characteristic or it still retain its own self albeit more power???
 
you don't bore the 16B to 1800cc, the more common method is to stroke it up to 1800cc, you can bore it bigger but it sacrifices the integrity of the block for high hp engines.
 
it'll just make it a B18C. Yes, 16B should be left alone... There isn't any other 1.6L engine that comes close to it, even until today.

Remember that this engine puts out more HP per Litre than a Ferrari 360Modena.
 
agree agree, how bout those Spoon's B16B or other tuners complete B16B engines? has anyone came across some??
 
fully built engines from Spoon or JUN costs an arm & a leg, only a very wealthy privateer or team can run those stuff. these engines are on everybody's wishlists. :D

example a Spoon F20C 2000cc or 2200cc engine costs JPY598,500 ($5,460) & that's just a bare engine (no flywheel, intake manifold, throttle body etc) so you when you add all the others up later on it can easily go beyond $10,000.

18c & 16B costs a bit less as the catalog i downloaded from Spoon doesn't indicate a full engine, just an overhaul kit.
 
i see..........well there are one B16B that is turbocharged whilst adding a four throttle intake system on it, it kept the 1600cc (well normal ppl will stroke(not bore, learn my lesson) it to 1800)but everything inside is well balanced and have been fitted with racing uses parts, the valve's, Hi-cam, everything and it produces 200hp/8000rpm and 24kg/m 6800rpm on a 0.4bar of boost(its a small turbo), now that was realli realli fast on track, it kinda being fast on corners although lose to imprezas and evos on straight, but its cornering time are actually way faster than the others, i wonder what suspension setup or mod has he done....(a person from thailand)also, it kinda being 890kg light only as the car was fitted with carbon bonnet, carbon rear door, carbon side door, and everything inside goes(just like normal track cars)....
