I have already asked this question but I need more reasurance. I am planning on running a td05h(14b not16g) on a b16. Too small? I was told by some of you guys that it would be just fine and I felt good about it until reading this..

The argument was made by marty that since they boost to 8k on an eclipse or evo that they should just as well on a b16, but supposedly a b16 head flows alot more cfm's than a 4g63 head making the turbo spool too quickly and lose boost early in the rpm range on a b16. My main concern is that when Im on the highway doing 80mph at 4k rpm's Im not boosting getting 18mpg. Any technical help, websites with uplifting info, or personal experience with this turbo on a DOHC VTEC honda motor would be awsome.

 

14b is going to make full boost probably at around 2500rpms... it will be useless by 7K, especially on a Bseries.

If you want to be going down the highway at 4K and not be in boost, you're looking at something like a T3T4 60trim with a .63AR.

 

Sorry but a 14B is good for a B series. They are put on 2000cc engines stock so with 400 less cc with a B16 you are going to spool slightly later(around 3200 to 3400rpm) and it will make power up top fine as the 4g63 makes power upto 7800ish rpm stock. The B16's head flows great and you are right but to tell the truth and what alot seem to either not know or forget is that the 1st gen 4G63 and the 3rd gen 4G63(EVO) is one of the benchmarks of stock boosted 4cyl engines. They flow fine and the 4G63 without aid from any variable timing makes around 140hp in N/A form which is right where the B20/B18B's power sits. The heads on B20/B18B's can flow just as much as the B16/B18C's heads with different cams added.

 

Right, but for practicality reasons the 14B is gonna be a bit on the small side. The B16 tranny is way on the short side, he'd be stuck in boost traveling down the highway even in 5th. Also, depends what PSI and what manifold he decides to run. I'd say that 15psi and a tubular manifold would smote the 14B up top pretty quickly.

I guess the best question would be to ask... what kind of power are you looking for?

 

14b=cheap supercharger either way you look at it. we were seeing a full 16psi last night at 2700 in a b18a1

 

Thanx for the comments guys but this is why Im still in depate about this subject is because I have marty, a guy who I think knows a thing or two about turboing a honda tell me that it should be a pretty good match for the motor and then I hear other people tell me they used a 14b on a b18 and it spooled 16 psi at 2700! Honestly common sense tells me to agree with marty but on the other hand I still have doubts in the back of my mind. Really my only concern with the whole thing is boosting on the highway! Now correct me if Im wrong but it seems to me like boost wouldnt come on at 3-4k or even 5k on the highway if your cruising at very partial throttle. now as soon as you push on the gas and open the throttle boost would come on. Im assuming that when someone says a particular turbo with reach full boost at "X" rps they are assuming your at WOT, am I right?

 

14B will NOT make 16PSI at 2700.











but if uve got one that does, Ill buy it!

 

you sure..........ill get a pic for you thursday night

 

hey man, I might have made a mistake.........Its sat nite, 2:44 am.........And ive been doing some boozin!
