I'm trying to figure out what turbo will get me to the 350whp-400whp range in a built D16Z6. I'd like a fast spooling turbo but I also wanna hit my goal on 15-20psi. I also wanna go with the best bang for buck. With budget issues the lower the cost the better.

I've read tons and tons of threads which all seem to contradict each other. These are the turbos I'm looking at:

EvoIII Big 16G
GT28rs
GT30r

I'd like to roll with the 16G because I had one on my built TSI and I was in love with the response of the turbo. Fully spooled at 3200 with 22psi on the street

Let me know what any of you think because out of all the sites I've found this one seems to have the most friendly helpful users and the fastest replies. Thankyou in advance for you replys and if you have experience with any of these turbos let me know how it turned out for you!

My vote is for the precision billet 5431. Way cheaper that the gt stuff, good spool, 400whp no problem.

Easier to find a manifold for a t3 than the 16g would be.

K7-1Ktrevor

your not gonna hit those numbers on a 16g unless its on alot of boost. I love my 16g on my ls but if you want a good amount of power hes right the billet 5431 would kick *** and t3 manifolds are everywhere.

Sorry to say but without a magic wand, spool and 400whp d16 shouldn't be used in the same sentance. A guy I know went from low 300's with a gt28rs to low 400's with a gt35r on a sohc, gained less than half a sec in the quarter.

I'm presuming it's a race car, so your best bet is to make the head flow to a higher rpm, that way you'll have a more usable powerband.

Dee6teen

I'll do some research on the billet 5431!! Thanks for your responses and your input is MUCH appreciated!!!!

Schister66

Let me get this out of the way first of all, Hondas are not the same as DSMs. They have garbage head flow which is why boost comes on so quickly (its a measure of resistance in the most basic sense) yet does so little in the way of power creation.

Anyway, for 400whp out of your D series, there are a range of turbos you could use. I dont know why you would limit yourself on the basis of PSI unless you're trying not to buy a good MAP sensor. Boost isn't the problem...So moving on.

What fuel do you plan to use?
What is the use of the car?
The turbo needs to spool quickly yet still reach 400whp, are there any other criteria?

Until you answer the fuel question, there's no sense in moving forward with a suggestion. I could give you a list of turbos that would generally fit your needs but the exact one requires a little work on your part first.

Dee6teen

Alright I like the fact that your asking me questions, means you're really trying to help me out in the best possible way. So hopefully I can answer your questions.

Fuel: 93 pump gas
Use of car: Street car but i also wanna take it to the track on weekends.

The turbo doesn't have to spool super quick but with the lack of bottom end I'm going to have going with 8.5:1 pistons I want something that can help make up for that. I'm trying to hit 11s in this car at the track and from what I've read it's totally possible in the 350-400whp range. The engine is a Z6 with Y8 head. I haven't figured out what the tranny is yet.

I'm planning a vitara build with eagle rods. Not sure if I wanna spend money on the head but I am willing to spend the money on the intake mani.

My buddy who just had his CRX tuned at JKtuning is running the Garret 60-1 and it makes pretty nice power but not sure if I wanna go with that turbo. He is running a GSR with type R cams and I don't think I'm going to be able to spool that turbo like he does without a serious intake mani and some head work.
Looking forward to what you have to say Schister66!

racebum

mmmm.....toss the d16, get a b18c and use a 5557 is my first thought

i've had a garrett t3 super 60 which i had on a b18b and it made really nice mid range and pulled right too redline spooled basically instantly and before i had it it was on a d-series and the guy loved it... great turbo for fun on the street and can reach ur hp goals with quick spool and cheap also

Dee6teen

I'll do a bit of research on this turbo, still curious as to what Schister has to say. I like the twin scroll and the stage three version seems to have enough HP and then some to get where I want to be.

racebum

super 60 is stretched at 300whp if that. it's smaller than a 50 trim. pure t3, flow isn't in the ballpark of what you're after

K7-1Ktrevor

I had a t3 super 60 on a mini me and hated it. was just as laggy as a ebay t3/t4 and didn't make the same power that the ebay turbo would. Id take a 16g any day of the week over one. my 16g makes boost under 2k on my ls right now.

And a divided housing will not help you in this case either.. So.. Listen to Schister66

Dee6teen

Yea I'm waiting on his response.


K7-1Ktrevor I have a question for you, what's your setup like on the LS turbo? My best friend is running an LS swap in his EK(EJ8) and is looking to boost in the future.

Dee6teen

I like my Honda's like I like my women...with D's not B's!!!

K7-1Ktrevor

I have a ebay evo8 tubular manifold with a b series flange welded to the back and port matched and the holes drilled through. the evo8 ports are spaced a bit more so the manifold isn't really idea but it works pretty good for what I need it for. Im also running evo 9 560cc injectors and some home made charge pipes and d.p. the crx that the kit used to be on made 328wtq and 329whp on 22lbs on a stock ls, ran 11.4 @128. mine is in a civic wagon, just hoping for 12.2s or 12.0s

K7-1Ktrevor

honestly in my opinion the 16g is great and all but a ls would be better suited for a nice 50 trim t3 turbo. my car makes soo much low end and mid range tq its really hard to get it to hook for **** even on lower boost levels.

Dee6teen

Yea I was actually wondering how the hook up was with that turbo hitting full boost so early..I'll let him know about your setup because he is on a budget and I think he should piece together his set.

Schister66

The fuel makes this choice a bit tricky. You're going to need something a little larger than what I would've normally selected since you're trying to make this power on pump gas. In regards to your friend with the 60-1, that turbo is way too large to run on your D series. I ran a 60-1 on my GSR and hated it...i sold it immediately because of the lag. Your D would be even less responsive.

I'm honestly not sure which turbo to suggest to you. To make the power you want, you're going to need a turbo that flows roughly ~48-52lb/min. If you want to get a general idea of what a turbo is capable of making, multiply the lb/min by 10 and that gives an approx brake horsepower. In this case, the turbos i'm suggesting will make between 480-520bhp then after friction/drivetrain loss, you get whp...i use 20% loss for easy figuring (384-416whp). This is only an approximation.

I wouldnt go with something as small as the 16g (or possibly even the GT28rs) if you're looking to hit your goals on pump gas. The turbo is a little small for your goals AND fuel combination. If this was on E85 or race fuel, my choice might change a little.


So far, i've come up with:
GT3071R, GT3255b/e (PM TheShodan), T3/T04e 50 or 57 trim, S258 .55ar, etc...

Shodan, your thoughts?

Dee6teen

What about the 3231e or the 3431e? After doing much research I'd like to use one of those but I'm not positive how laggy they would be. Any thoughts on those two particular turbos Schister?

I'm really leaning towards the 3431e after pluging in your numbers and checking a few turbos out.

racebum

if you go precision the 5431e is the one you want. it's 50lb/min and uses the light billet aluminum compressor wheel. it will be more responsive than both the 32 and 3431e just by design. the really neat part is it only costs $75 more

if you can pony up something like that 3071R or 3076R would probably be even better yet. the conundrum you have is with a d16 and wanting at or near 400whp with a fast spool.

TheShodan

iTrader: (14)

Those are the old series. SC34=57 trim. SC32=50 trim

Schister66

I never have understood why people would be willing to pay more for a PTE SC34 when all they're really getting is a 57 trim.

Mac, what can your GT32 series make on a D series? Would that be too small for his goals on pump gas? I'm sure you have something up your sleeve...

TheShodan

iTrader: (14)

Was thinking about about it. He may have to do a GT3251B Journal bearing, the smaller of the two, if he still wants 400whp. He'll be pressed to go over 20psi and do it, and would still need a type of fuel that has the ability to resist knock (Like Meth-water, race fuel or *gulp* E85), but that would be able to do it as long as he has the correct camshaft and good tuning ability. He doesn't even need a billet aluminum designed wheel to do it..

phat00civic

I was going to say the 16G is probably too small for his application or use. I am not pushing 400HP, more like 210whp on a 15G at 10PSI. The 16G is a bit bigger but not for range, although it might help you on low end power. I do like this GT3071R but still trying to look at a good a/r to get you where you need to be on that D series. Also while minor were you looking at doing an internal wastegate or external?
