Because its a waste of a perfectly set up platform. There are many other b-series motors that you can use to get what your looking for, give someone else the B18C5 and go buy and LS. I would do the cams, pistons, etc. for reliable power, I would spend the extra $$$. I have had a turboed B18B1 its fun, too much torque even with an LSD, it was only a straight line car. If money is an issue dont bother building any project, you get what you pay for, I spent 5k building my turbo setup from a garrett Gt25r bb turbo, tial bov, hondata s300, trans build, rc injectors, etc. I got the LS to 276WHP... My 2 cents...

When does a B18C5 stop being a B18C5? Once its bored to 2 liters, new pistons, cams, valves, springs, rods, crank I don't consider it a B18C5 anymore. B18C5 is a reference to the stock motor with stock internals. I stopped referring to mine as a type R a while ago...

(. )( .)

even though ive seen alot of boosted c5 builds, i agree. the engine works fine as is, a mild NA build just adds fuel to the fire!

racebum

why? it's still a b18c block, they are all p72 castings and all the same thing.

you can change all you want and still have an itr block

yup im about $10-11k into my 81.5x84.5 destroker C5 motor as well. I'm expecting something close to your numbers when i tune this coming up week. Really, ill be happy with anything above 176whp from my 1.76L B18C5/PR3-4.


Hahahaha thats where i have been for months now, waiting on machine shops, waiting on custom CP pistons, waiting on camshafts, etc etc however as of now my C5 is also making 0hp LoL

cibao2ner

why destroke the b18c? for more rpm?

S2kRyan

Are these $10k+ N/A builds for power in the first place? If so you guys need to find yourself a new tuner...

4DRDB8GSR

Exactly my goal was safe RPM well over 10k so i needed a higher Rod/Stroke Ratio, with a 84.5mm stroke i was able to fit 140mm rods vs the stock 137.9mm rods with the 87.2mm stroke the shorter stroke relieves side wall stress and makes the rods/pistons sit down straighter in the cylinder.

S2kRyan

I agree with this completley. Ever since my S2000 days I have been a HUGE fan of gearing on hondas. It is by far the best bang for your buck and doesn't sacrifice reliability at all. However, this isn't what the OP was asking about, although the higher final drive will free up gobbs of torque to the wheels. Nothing like a nice set of light wheels and a higher tooth count FD to get the most out of your current motor setup.

S2kRyan

What is the point of taking away the little but of torque you do have and moving the redline up so high? What cams will you be using that you expect to make power above 10k rpms and only put down 175whp? I'm sorry but if you could explain the reasoning for your build a little better, it doesn't make much sense... Why rev so high and not make any power? Or are you just doing it to say you rev over 10k rpms?

Also, IIRC, the RP Racing ITR only reved to 9800 rpm and made 250+ out of a 2.0L block. It did have a Skunk 2 CNC head and all the other bells and whistles.

If you are doing this build for some kind of road racing reason, then you could have saved yourself $9000.00 and just purchased a 4.7 or 4.9 FD and made more torque and been ALOT faster around a road course than sitting at 9-10k rpm trying to pull out of turns. Torque is what pulls you out of turns.

H-PIMP

Reliable, 100K mile daily driveable, 210whp is realistic. Built, tuned, and, maintained properly.

240-250whp is possible without going 2.0, but the life expectancy will be way down. High compression, high revving, high hp n/a B series aren't really known for their life expectancy.

lol ^^^ My jdm b18c type r made 194whp untuned hahaha

Yea seems kinda odd i had a b18c5 in 04 and we had it at 227hp for 3years and was a 5k bulid just keep it simple those motors can take a beating if bulit right and has a great tune plus u can tune a stock ecu and still make power. Yea it depends on the tunner and builder and just do a lot of research.

i have the 4.9fd in my R and it makes a nice difference over someone who doesnt have one. Awesome upgrade if you ask me.

racebum

how exactly does tuning a stock ecu work? no one makes support for obd2a or obd2b

HYREV2NR

More than likely referring to a VAFC which I am not a huge fan of being Hondata is the way to do it correctly.

racebum

oh lordy, a vafc can comp for minor mods but they have a very narrow window of change. you can't change the injectors or really even cams well. all one of those does is jump in front of the factory signal. you also can't change ignition tables

HYREV2NR

^^^Yeah and I remember when a VAFC and a re-chipped ECU was the only way to go. Thanks God for S300.

You bumped a 2 year old thread just to post this?

the cheapest way to make the most tq/hp is to do a nice kswap.

my stock tsx motor puts out more tq than a fully built streetable c5 motor will ever get you.

gwarfare

Well anything these day can be tune,plus a kswap is ok,not the best for dd,seen a lot of kswaps go bad after 30k. Seen b18c5 last years if "bulit right" do what u want but now chp in Cali is starting to crack down on kswaps and the state ref is getting tougher to pass? Was just there with a buddy of mine doing his kswap to pass and it failed visual inspection,he has droped well over 15k with swap to pass legit and they said no.

blacK_Dc4

lol a stock longblock? otherwise, i highly recommend tuning it.
