I have a 97 civic dx that we have done a mini me head swap on as well as many bolt ons. V-afcII walbro 255 fuel pump and aem fuel rail regulater, msd complete ignition system and skunk2 intake, exhaust all the way back other parts as well. I have just completed the turbo (14b) setup and apon starting the motor we realized that the intake side has a bad seal and is throwing oil into the charge pipes. what i want to know is screw the 14b and what kind of power do you think i'd be looking at with a 16g. i know it takes a little longer to spool up but besides that how am i looking?
thanks in advance

 

How much power are you looking to make?
I would go with the 16b.

 

see thats the thing that i am trying to figure out. i know a stock civic dx is 106HP but with everything i have on and am putting into the motor my goal is around 200 or so. the only reason that i am looking doing the 16g is because the thing is identical to my 14b just a little bigger turbines and it will bolt right in place. we still have the turbo setup on the car and all we are trying to do is have a new one and unbolt the old one and put new one in and go at it.

 

Check ur turbo oil or coolant piping there could of been a losed bolt or a crack on the pipe and about the 200WHP i thing u got it closer that u think (I recommend to DYNO-IT) when u bolted the Turbo and find out ur specs

 

the other day i took the pipe off that bolts up to the intake part of th turbo. ya know the pipe that goes down and feeds the intercooler, and when i did i had someone start the car and as soon as they did and we tried to rev the engine it started blowing oil at me. there is also oil in the intercooler so now i have to take that off and clean it out and that is why i am thinking of just going to a 16g plus it has a warranty

 

Well if you run the 16g, i would only run about 8psi on stock internals, it flows alot more then the 14b, and running 10 with it would certainly lead to some nasty engine issues. Also make sure you check your oil pressure. What size oil feed line are you using? Stealthmodeperformance.com sells an oil restrictor which is cheap insurance to help keep pressure down, i run that on my 14b set up. Also, i dont suggest boosting long with nothing but a VAFC to control the fuel. Look into chrome or uberdata so you can tune fuel and timing correctly.

 

I know its not to much better but i also forgot to mintion that ihave a 12:1 fmu. Also so lt me ask another question, when i did have the turbo in the car and the car was running my boost guage was down in the vacuum around 15 or maybe a little more and when i would rev the engine the guage would should up to maybe 1 pound of boost but take the engine a second or two to rev up. what could be causing this? i have checked all my vacuum lines and the person that i bought the original turbo (14b) he told me that the wastegate was set at about 7-8 psi.

 

Your car is supposed to be sitting in vaccume at idle. Your not going to build boost by just reving the motor, there has to be a load. Once you take it out, it will spool to about 8psi. If it doesnt, then you have a boost leak somewhere, or the wastegate isnt sealing properly

 

I'm making 433hp on a 2.0L 4g63 and a self-hacked 16g with 550cc injectors. At 1bar, a 14b flows 390 cfms. A small 16g flows 505 cfms, a polished big16g will flow 560cfms using the same TD05H compressor housing. You will be running .5 bar. The 16g's flow way more once they spool than a 14b will... but the 14b will be more efficient at lower pressures making it a whole lot more driver friendly. You will be driving a lag factory if you bolt a 16g on a 1.6L... and once it spools, .5bar on a 16g delivers a LOT more cfm than a 14b.
