I've boosted one sohc it was d16z6 and it was fun and now i'd like to try something new i wanna build a b18b non vtec but I wanna know if im using a t3/t4 55 trim trubo will a vtec b18 be anymore beneficial from a non vtec is it worth the money to get a vtec b18 or not I'm gonna use a gsr lsd tranny. Im not looking to build trying to stay stock thanks for everybodies incite into this and for everybodies help.
which is better

boosting a stock LS vs a stock GSR can put out pretty close to the same numbers. The lower compression i the LS can allow for more boost to help close the gap in power compared to the GSR.
That was a great answer thank you
IMO, As a DD, you should be more concerned with mpg...
I say start a separate build for your weekend track fun, this way you can build it up as much as you like and not have to worry about legality of emissions, etc...and also show all of us on CC your progress as you go...
BTW, what kind of mpg does a Turbo'd D series & B-Series get? My EX is not FI, but it's common sense...when you increase air and fuel flow in the engine, you are going to be burning a lot more fuel and producing more emissions...

Most turbo'd civics whether B or D series tend to do better on gas mileage after boost (as long as the driver drives normal, which tends not to happen because boost is fun). You're right about the increased air and increased fuel, but consider the fact that you need a lot less throttle (less air) to accelerate than before when driving like a sane human being. Once you upgrade to larger injectors that have a higher minimum flow, then yeah you'll be using up more fuel period. Boosting a D or B isnt your average everyday mod, so i try not to compare the not so average extreme fuel upgrades either.
Turbo the D.
Listen to what go traction has pointed out.
300 whp on a low comp built bottom end D series is far from pushing the limit. There is plenty of room to grow and a large margin for tuning changes there. 300 on a stock B is also easily achievable with a very competant tuner. You are getting close to that "basic power ceiling". Sure peole have made a lot more power on stock Bs; but there would be that concern of how long is it going to last. The power on a built D would be a cakewalk, safe and reliable w/ a sufficient tune. (And would more than likely make quite a bit more torque than a stock B18C).
$ for $ the turbo D is also more beneficial.
I would also drop the 35R/Vitara idea and go with a much more reasonable/usable turbo. A .55 or .63 50 trim would be my first choice, followed by a 57 w/ the same exhaust a/r. Make usable and enjoyable power.

they were not designed to hold much boost. for me it leaked at 16psi, for others around 18. thats why i had to upgrade to the tial 50mm
as sad as it is when these threads get posted most of these questions are for no reason. this person will more than likely NOT ever turbo his car, let alone build a motor for boost. Autoworks has alot of experience as well as product knowledge to back it up. i can only speak for what i've done and what i've seen done. im pretty knowledgable in the turbo d series game, and like i said if i dont have the answer i know people who do.
its all about ignition timing and afr's
a stock d-series isnt built to handle massive boost power...neither is a B-series. Both can be made to handle it and regardless if the motor is built or stock, ignition timing and air/fuel ratios are key when tuning.
this thread is starting to turn into a pillow fight.
Id say do either one. Your lookin for a kordenbrock mani for your car, so IM deducting that you live in or near cincinnati. You know what boost the d, you dont see too many turbo y8's around here makin that much power, so throw it together and get ahold of dave blundell and have him tune it. (if your close to cincy)
anyone that suggests a D series has more than likely never owned a stock b series turbocharged.
lmao...ok. i've owned both. i've also driving MANY other turbo cars. the d series is deff the most fun

-_-
displacement is greater in the b18 so you have potential for more torque than the d16. so if we theoritically have these two engines making the same whp, they are not making the same wtq. understand now?

i disagree.....and here is my proof
here is a 905whp 538ft lb toque b series
and a 609whp and 404ft lb torque d series
if the d series made as much whp as the b series it would made more torque

obviously those are not stock internals.
Bone Stock d16 using a 60-1 bullseye turbo
Bone Stock b18 using a Greddy 18g turbo making roughly the same whp
Powerband depends completely on everything involved in your setup from type of d or b series motor, to exhaust system, to your tune. Also, no two motors are the same. My point is it is pretty impossible to answer the question the OP posted accurately. thats why i said theoretically in my first post
