turbocharging the b16b, my turbo b16b build/log opinions welcome.


I am pretty sure I am going to go for it.
Having done some research, Artech tuning has done a few turbo conversions reliably on DC2s on stock internals (b18c engines) which have higher compression than the b16b have they not?

Honda Integra SiR / B18c swap / Turbo kit / 285.9bhp - ARTech Tuning Ltd :: Engine tuning specialists in Guildford, Surrey. Custom tuning on Honda with eCtune, S300, Kpro, K100, etc.

My power goal is only 280bhp, which I'm lead to believe can be produced with modest boost, around 7psi?
 
Raiden why are you comparing 2 different engines? They have completely different piston designs. While i don't doubt 280bhp can be made reliably with a good tuner and high octane fuel the issue is that is only 238whp, most people who turbo there car are after 300whp or more so what will you do when your car is finished with the turbo then 2 months later you want more power? You will turn up the boost then blow up your motor, this happens to nearly every turbo b16b owner, you simply can't make enough power safely to be satisfied. The evo9 turbo is actually an outstanding match for a Honda motor as long as it has the larger turbine housing.

Do all this at your own risk but i strongly advice at least a .050" or 1.3mm head gasket, this will bring you down to 10:1 which is much safer.

Keep in mind it is rumored that the design of the b16b piston causes it to be prone to hot spots and poor flame travel due to its massive dome, many believe this is the sole reason of it failing in turbo setups while the ITR has dome is much smaller and flatter compared to the sharp angle of the b16b pistons.
 
Why dont you do as i have done and stick a set of b18c5 pistons in the b16b ? This will bring your comp down to around 9.2:1 which is good for boost. Your playing with fire turboing a stock b16b...

I do understand where you are coming from mate in regards to the my power goal.However, I do believe 238whp would suffice. Having said that, turbos are addictive and I guess, after my first hit I will crave for more:)
Interesting, about the piston differences.
After reading all your turbo posts, I trust your judgement.
The last thing I want to do is blow my motor up.

ps-the evo 9 turbo is a rebuilt unit with Garret internals - 57 trim with 0.63 back housing...any good?

Cheers

Where can you get the b18c5 pistons from?
Is the b18c5 the american equivelent to a b18c mate?
Will the b18c5 pistons work with the b16b rods? If this is the case, how would they lower they compression to 9.2:1? Would they not simply take the compression to the stock b18c compression?
I read it was 11.1:1?

Cheers

Welcome to RS Machines.com

The reason why they lower the compression in a 16B is because they have less aggressive domes and are nearly flat if you compared them side by side.

If you find this is too complicated for you and you just want a "just tell me what to do" answer.. uh... don't go pointing fingers if your motor takes a dump... caveat emptor.

just wait, i hope to get install pics and dyno graph soon:) but projects going to be delayed by 2 weeks though, i have to go visit my father from 01/03/07 to 01/13/07 its been awhile and if i dont go now i may never see him again :( i dont know how old you guys are (im not that old myself) but im sure some of you guys know what i mean.

I would kind of appreciate it if you didn't dig up stuff i talked about 3 years ago, my father has since passed and it is a touchy subject, i come here to read about cars and try to help people, not be reminded of what's in the past.
 
thinking about boosting my b18c at the end of the year. fears off it blowing are putting me off though, sadly i know how it feels when your engine goes boom ha
 
gutted mate:(
I am in the same boat really except with a b16b.
However, Ricky has been doing builds for a while, and has a seriously good rep, even with turbo'ing stock b18c's.
Artech tuning have turbo'ed a fare amount of stock b18c's too, with amazing results...with reliablity still being key.
After all the information I have siphoned through, I am confident it can be done, as long as you have a good enough tuner that is experienced in mapping high compression turbos.
Have a readup on honda tech too bud. They are some seriously informative b16b and b18c turbo threads on their:nice:
 
I plan the following configuration:

b16b block
b18c5 crank
b18c eagle rods
b18c cp pistons (81.5 mm, 9:1)
arp head studs
kms engineering block guard
acl race bearing
gsr camshaft
victor x mani
hondata s300
rc 750 cc
walbro pump
4.4 tranny
competition clutch st.4
hks 2530 turbo
apexi i/c

How you consider, what hp (whp) will show?

Romain @ Artech/Eurospec tined the ecu on my car, stock b16b, only thing changed is 440cc injectors, and tweak on the distrobutor for the timing. Ive only just got the turbo kit fitted, but it previously ran fine on another stock b16b for 18months and made a solid 270bhp at 6psi. Depends on your powergoals i guess but mine goes like a rocket ship tbh and is perfect for street driving imo
