I've run one on a buddy's car but it was a sohc, how would i go about getting one to work with a b-series? Most b-series manifold's are t3/t4, I'm guessing i'd need an adapter fab'ed? I'm only looking to make 300whp on a b18b1. Would that be too much hp for that turbo?

 

I have a 14b on my b16. I bought a cast manifold with a t25 flange then got a adapter machined to go from the t25 flange to the dsm flange. A word of warning though, the bolts that attach the turbo to the flange thread into the exhaust housing on dsm turbos so if you don't get a manifold that through bolts from the top you will not be able to use it unless you drill the exhaust housing out so you can bolt the turbo up from the bottom. I can post pics of my set up while its off the car if it would help.

 

There are many dsm turbos, the most popular being the 14b and the T25 which neither of them will be able to hit 300whp. Check compressor maps and do some calculating. I would suggest looking at a 16g which is an old evo turbo but it they are fairly cheap and it would reach your goal!

 

i would suggest an evo 8 or 9 twin scroll turbo with a custum twin scroll manifold

check this out
Car: Honda CRX

Engine: Bone stock JDM GSR, Skunk2 intake manifold

Mods: Custom divided EL manifold, Evo 9 turbo, stock o2 housing, 3" dp, 3" exhaust, no cat, Evo 9 intercooler, Evo9 intercooler piping(modified to fit)/bov, Evo 9 injectors, Walbro 255lph HP pump, GM 3bar map sensor, Neptune

Tuning on 93 octane at 12psi:


*This was very impressive for all Evo 9 parts from the customers Evo 9 that he did a turbo kit upgrade. Instant spool, great powerband and great drivability. The pulls were all done on the base wastegate actuator level (12psi).

this is one of the best powerbands i've ever seen for a daily driver

 

Agreed. Those turbos are small. Get a 16g or an evo turbo as spoolin mentions

 

You can make 300whp on a b-series vtec motor with a 14b. I made this with a bone stock b16a. Really stretching the limits of the 14b though. I would reccomend a t3 super 60 over a 14b, t25, or 16g. Figure you will want more power down the road, so why not get a manifold that can support a t3 frame later on.

 

yes but it will only be like 60% efficient

 

i made 340hp on a 14b at 20 psi with meth injection.

 

I had a custom log made with the DSM 14b flange to fit my b16. it was a blast to drive

 

could you post up your dyno id like to see the powercurve

 

Same here, i want to see the graph, tvgz28

 

i got some adapter plates made for t3 to dsm turbo. I have 3 left to sale. Let me know. I have one of them on my eclipse so i could put a t3 flanged turbo on it...
