s16g w/14b exhaust housing

[coryd]

i just bought a s16g from a buddy who totaled his car awhile back. the exhaust housing on the 16g is badly cracked around the wga. i have an extra 14b laying around with good ported exhaust housing. i was thinking about putting the 14b exhaust housing on the 16g. so in theory wouldnt i build boost faster then a normal 16g because im pushing same amount of air into a small housing in turn it would cause the wheel to spin faster and build boost quiker??

what do u guys think?

well 14b,s16g,b16g and evo 16g all have the same exhaust housing the tdo5h but puttin the ported one on will be a good upgrade itll help will spool up, and boost creep

They do not use the same turbine housing. The 14b uses a 6cm housing, the small and big 16g's use a 7cm housing, and the evo 3 16g uses a slightly different 7cm housing. You can use a 6cm housing with a small 16g because it uses the same turbine wheel.

O my fault thanks for fixing my error.

I use a 14b housing on my evo 3 because all the mani to turbo bolts snapped off cause of the ### metal gasket. I havent had a problem with it yet and it actually spools quicker so.....then again i DO know the drawbacks to a smaller turbine housing.

ya, im hoppen for a quiker spool up because its mainly for streat use, once i get it all done i will let u guys know how it goes

I hope you dont mind running 18-20psi minimum. I put a small 16G into a stock turbine housing and it would not hold any less than 19psi. So I set it to 19psi and it holds solid till redline. Just make sure you are prepped for 19psi all the time.

Sorry for bringing this thread back to life, but I got a question. Would using the 14b exhaust housing onto a s16g be an upgrade? What is the tradeoff for using a smaller, 6cm exhausing?

I think with a smaller housing you would get a little less fuel economy, heat dissapation would be alittle less efficient, and you may loose a little top end. Of course, this is based on my thinking logic. The differences will probably be so small you wouldn't notice. I definately wouldn't call it an upgrade by any means

I figured the top end would suffer.

Great mod for guys running automatics. Makes launching and driveability so much better. Difference in spoolup is about 400-500 rpm or so. I got full boost by 3000 rpm on a 6cm housing vs. 3400 rpm on a 7cm. I had a 10* clip on the s16g/TD05 wheel so that helped the topend but hurt spoolup a bit.

Its definitely much quicker spooling than a T28 for instance. Based on my butt dyno I'd have to say a loss of maybe 15 h.p. on the topend.

well, after some time testing it i ran into problems with boost creep. it would spike up like 2-3 pounds but would hit full boots about 750 rpms sooner. and this was with a very nicely ported 6cm housing. so i wouldnt recommend it

Your topend will be horrible. I ran my 18g with a 6cm housing and it was actually slower at the track than my 14b was at the same boost. The problem was the motor was outflowing the turbo at anything over 6 grand causing boost to drop to 15 pounds. This caused the car to run pig rich up top.

I just threw a s16g into my ported 14b/6cm exhaust side and went from pulling 13.2@102 to my current 12.8@106 so I wouldn't say its a bad combination at all.
