Im boosting my B16 with stock internals and a ported head, what would be the best turbo size for it? Planning on running around 10 psi. One of my bigest queries is how fast a t3/t4 spools up? If its got crazy lag i was thinking of getting a t28 but im woried the t28 just wont compare to the top end power of a t3/t4! To be honest i would prefere better high end power but would be nice to get some feedback on the differences between different sizes (not just t3/t4 and t28).

As you can probably tell im pretty confused please help me

 

First of all, we need to know a little more about your setup before we can give you a good recommendation.

1. What are your power goals? Generally for a stock B series, you're limited to 300-325whp.
2. What do you plan to use the car for?
3. What characteristics do you need from this turbo?? Basically how important is spool vs overall power...
4. What's your budget?
5. Whats your setup so far??

Once you let us know the answers to the questions above, we can give you more specific suggestions on a turbo for your setup.

 

My setup so far is 2 1/4 inch cat back exhaust with decat, ported head with 3 angle seats, lightened flywheel, i will be running a front mount intercooler, a turbonetics external waste gate and manifold. Everything else is stock.

I have a pretty low budget but if i can get some ideas of what i can get for my money i can let you know if im willing to save up and spend that much.

Power wise ill be happy with mid 200 because of my budget and the fact that the car is my daily driver.

Im new to forced induction so any tips and advice are really appreciated if you need any more information just let me know

 

gt28

 

If you're looking for mid 200's, you could get away with using a T3 Super 60 or a T3/T04e 50 trim. Those two turbos will spool up very quickly and make the power you need. The best part is that you can find them for very little money. The Super 60 is like $500 new and around $300 used. Check through the marketplace and see what you can find

Money is low...did you read?? Not sure that's exactly a "cheap" turbo

 

thanks for the help, ive looked around a little bit and found one site with these claims/figures on their turbonetics turbos:

t3 50 trim 250-270 hp

t3 60 trim 300-320 hp

t3 super 60 trim 315-395 hp

They are all $745

So this makes it look like the t3 50 would be best?? I was just wondering, because you reccomended the super 60, have you had experience with this turbo? I would trust your word over that of someone who is trying to sell me something if you have.

 

You're a little off on the turbos i was recommending. I was suggesting either the T3 Super 60 or the T3/T04e 50 trim. The 50 you found was a straight T3. That turbo is going to be too small for your B16 IMO. The problem is that it will flow too little air at high rpms causing your car to "fall on its face."

The Super 60 is as small as i would suggest going...

the most ive ever seen out of a super 60 is 320 whp i don't think that is right

and i wouldn't buy a turbonetics turbo to me its like an overpriced ebay turbo ive heard nothing but bad about them not lasting any longer than 10k miles at the absolute max

The Super 60 is capable of more than that, but not a ton more. Its rated at 35lb/min which equates to right about 350whp on a VERY efficient setup. The turbo will make the power the OP needs without the unnecessary lag of a larger turbo.

The 50 trim on the other hand is rated for 46 lb/min which is about 460whp at the flywheel or around 400whp at the ground. If your goals are a little higher than what the Super 60 can accomodate, get the T3/T04e 50 trim

 

Ok im starting to think i need t do alot more research before i even start thinking about buying a turbo! all of these mixed opinions! ive been on a UK forum to get some help in finding a dealer over there that i could buy one of the turbos you suggested from but i just cant find one. Someone on the forum has suggested a t28 off a nissan pulsar gtir and this is the second time i have been reccomended this, it is definately cheap but im not sure it will provide the power im after (around 250 bhp) however they seem to think it will.

If i go for a t28 is there anywhere you know of that sells adaptors for a t3/t4 manifold to a t28 turbo?

 

Using a T28 like that is going to give you instant spool, but its going to fall off in the top end. Cars like the Pulsar can use a littler turbo like that because their heads are so inefficient compared to a Honda B series head. Honestly, look into the T3/T04e 50 trim. You'll be glad you did...

 

Thats what i was wuried about, ok thanks mate

but not turbonetics just get a garrett precision or BW

heres an idea for a fast spooling setup that could be had for pretty cheap with only one downside

get a used evo9 turbo and use that the downside is you would hae to get someone to make you a custom manifold that is flanged for that turbo

but i bet sls or spoolin performance or some other vendor on here could make you twin scroll mani for the twin scroll turbo give me a minute and ill find the dyno of this turbo on either a b16 or b18 vtec

 

^^The new Evo 8/9 turbo is the only OEM turbo i would ever consider using on a Honda B series. There are people who make manifolds for them, but from what i recall, they're a bit of a hassle if you try to retain the twin-scroll design

 

I like the sound of that, could i not just make an adaptor from my manifold to the turbo? If i can i think i can get one made, i used to work for an engineering/racing engine building firm, im still chummy with the people there so may be able to sort something out. Only concern is how much an evo 9 turbo is going to set me back?? Any ideas?

 

here is the setup and dyno i was talking about with an evo turbo but it was a gsr not a b16 but you know there isn't much difference in the two
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 was a gsr motor not a b16 though i think this is one of the funnest looking setups ive seen

id say 50 trim all day, youre number are off though. 50 trims will make upper 400's to the wheels.

i've heard that as well but never seen it

 

Nice one thanks for that looks pretty impressive, is it safe to run my b16 on 12 psi? Only thing im wuried about is the cost of this setup, buying an evo 9 turbo sounds kinda expensive to me and fabricating a manifold??

I dnt want you to read this and think im totaly clueless but im from the uk and have no idea what a gsr motor is? Im new to the american codes there mostly different to uk ones i think.

 

Ok would you lot say this is a good choice going with what you say it should be right.

http://www.full-race.com/catal...d=250

Its garrett so a good make and the price seems reasonable.........or does it? lol Being from the uk im not sure what prices to expect from US shops.

 

What psi to run is irrelevant, you could run 20psi on a small turbo, and make say 200bhp, but also make 200bhp on a big turbo at only 8psi because the big turbo flows the same at 8psi as the small turbo does at 20.

so ignore what boost pressures to run, and concentrate on how much power you want, and ask people on here what turbo to use for your set power goal.

for mid 200's and daily driver with less lag go for a GT28, but a gt28 is more expensive than say a 57trim t3 which would still do a good job but a little more lag.

any of them turbo's will be fine, it just depends what you prefer.... less spool time or not too bothered.

 

price doesnt seem too bad i dont think...... cheap compared to what we would pay over here in the UK anyway.

By the way with all these t3/t04's you want too look at getting the .63 housing not the .48.

you can get an evo 8 or 9 turbo used off evo forums cheap all day long
now the manifold would be a little tougher but im sure one of the fab sponsers on here would do it for you at a decent price

but its up to you i was just throughing out an option you probably hadn't thought of also those evo turbos are good to about 400 whp

 

Now ive found a garrett turbo for that price im swaying towards that option, even though an evo turbo mght not cost that much, getting the manifold fabricated and shipped over to the UK sounds like alot of trouble, thanks for the tip anyway!

Im starting to understand this a bit better now but just want to clear up what, for example 50 trim means? Also what is a .48 or .63 housing? Is it simply the size of the housing or is there more to it? I understand what the A/R is.

 

you don't want a straight t3 it'll fall off up top
if you get a 50 trim you want a 50trim t3t4

if your REALLY worried about lag get a t3t4 50 trim with a .48 turbine side

and for the people that will probably respond saying that the .48 is too small ive seen a t3t4 50 trim with a .48 hotside make over 400 whp
