Thread: B18C -R mods

Tune at Speedtech

Good luck getting 183kw with bolt ons.

Boost. 180kw from a N/A B18cR is hard / expensive work.

Are you just making up figures? I dont know anyone who has made more than 200hp or 150kws with just bolt ons. Whats your budget?

That's still 170kW...

With just bolt on's, you might make 145-150kW (So ~200hp) max, on a healthy engine.

Yea aim for 150-160.

Good start is quality headers Buddyclub etc
Full exhaust (debatable) but either 2 3/4" or 3"
Intake manifold / Larger throttle body - Skunk2
Tune - Crome / Hondata

If your going for 150/160+ kw your also going to need cams + adjustable camgears (and related headwork, springs, retainers etc)

^ at least stage 2's which then you'll probabyl need a bit fo head work done etc

250HP with just bolt on wont ever happen.
You could get 250HP at the flywheel tho but youd need to do more things such as bore out to 2L or raise revs to 11,000RPM and acturally make power that high. Which would require some high compression a lot of port work and some crazy cams and supporting valve train then have a fantastic tune. So with a budget of 20K you could do it NA.

Easyest way would be to just turbo it and a good tune. Could be done for 4-6K then.

how can you all say that it would only put out 200hp MAX, when Integra Type Rs come out with about 200HP STOCK.
a new intake manifold and extractors and a tune would all ready put it over that. so saying that 200HP MAX from bolt on aftermarket parts... doesn't sound right Champ.

ATW bro

Most cars factory power figures are im guessing at the flywheel. Since its much easier for us to measure power at the wheels most of us talk about power figures at the wheel.
Show me a stock itr making 200hp at the wheels and ill eat my face.

250 whp is about 70whp more than factory and is going to require alot of work and money.
you would need:
real agresive camshafts
adjustable cam gears
uprated valvtrain
extensive porting and probably modifications to the combustion chamber itself
probably oversised valves
intake manifold
full exhaust sytem headers inc
larger throttle body
bigger injectors
high compression either by high comp pistons or machining the head however youl want to put forged pistons and a set of aftermarket rods in also
a really good tune id go with a link g4 but depends on your tuner

also a question for all you people that like hondata and crome over link why is it you guys dont like link ecus? ive always used them and found them easy to use and have got good results.

Link = expensive and doesnt do anything needed that the stock ECU cant do with a Hondata or Crome Chip.

they do have alot of extra features that you dont essentially need but the extra features do make it run better if theyr setup properly. the older links like the link plus or the g2 are more like the hondata and crome and you can get them second hand for about the same price though

200hp, at the flywheel, on a brand new motor...

Put 150,000km's onto it, factor in drivetrain loss, and even the fact we have a different atmosphere to Japan (where the tune is written)... and you will be highly unlikely to make that factory figure.

Almost all power figures you hear of on these forums, and any others, are whp/wkw... not at the flywheel.

Bolt ons to make 140wkw, then a gearkit to make it feel like 180wkw. Done

Give the guy a break... lol as soon as he said "have already put on new air intake" you should know he's talking flywheel horsepower. Generally, if the engine has been well serviced and maintained, it shouldn't lose much power from factory.

Anyway, for decent gains to factory power you should consider:
- Getting a good exhaust (2.5" will do) with nice flowing headers (stepped tri-y or something)
- Running on BP 98octane (or Mobil 97.5)...
- Saving for a Hondata S300 + a decent dyno tune. (you'd be surprised what a good tune can do)

Just those 3 will give you a noticable difference which you won't be disappointed with... If you're really keen on making 250 flywheel hp, you'll need to consider cams + valve springs, cam gears, throttle body, porting/match porting... Possibly a rebuild if you're gonna go that far and spend that much... (it gets expensive).

As for turbo... don't do it! lol

Care to elaborate? or shall we not even go there

velvet47, better flame suit up mate... (unless you care to elaborate as 89CRWreck said)

Others have proved you wrong in some applications, not saying that 3" is right for this setup, just saying its a possibility. (Jtune? Search Honda-tech?)Nothing personal, but thats what grinds my gears about this forum, and others, people stating their opinions as facts

/end rant
