Twin Turbo D16. I need a project
 

I figure half the people who join this thread will bash but the first two points I wanna make are that Im bored. Ive got nothing going right now and I want a project like this.

Right now I have a built d16a6 with a t3/t04E 57 trim and its probably up @ 300whp or so but for my type of driving its really no fun. 1st feels like N/a, 2nd only builds 12 lbs and third has some weird problems, along with traction which basically is knowwhere to be found

I was thinking of switchin over to a twin turbo setup mostly because it would be very different and I thikn it could spool SIGNIFICANTLY faster.

The car is daily driven and pretty much never will see the track as its so far away.

I need some opinions on running a basic twin IHI or KKK set of turbos in parallel. Where they both get 2 cylinders, downpipes merged, charge piping merged so I can retain a regular intercooler.

I would be looking to run 15psi or so. But I just want to have fun with the car, rip on stoplights, having fun on windy roads etc.

Looking to make boost before 2500 or so

I am at a loss on how boost controll would be accomplished though. I think a 35mm wastegate that I have now would work, but combining it into the manifolds could be tricky.

Any advise appreciated. Im just looking for some fun for a winter project.

inefficient, cramped, and just all around dumb.

Re: Twin Turbo D16. I need a project
 

you would be better to spend your money on a properly sized ball bearing turbo.

Re: Twin Turbo D16. I need a project
 

Twin turbos are suited for V8's.

Refer here, just do this right. https://www.homemadeturbo.com/forum/...7865#msg817865

Re: Twin Turbo D16. I need a project
 

i think whitey did a twin turbo honda. if i remember corectly.

Re: Twin Turbo D16. I need a project
 

Somebody on this site started the install twin snails on a Civic.
I dont remember who it was.
A search would find out.....

Re: Twin Turbo D16. I need a project
 

I thought Whitey and Abaz have both done twin turbo setups?

Not worth doing IMO, like already stated a ball bearing turbo would do the trick, like a GT28RS.

Re: Twin Turbo D16. I need a project
 

how would spinning 2 turbos produce faster spool than 1 snail? you only have a 1.6L....

Re: Twin Turbo D16. I need a project
 

Its been done. Both times it wasn't worth it. Both times it was done for shits and because stuff was laying around to do it.

Re: Twin Turbo D16. I need a project
 

i do belive that is why turblow is doing it because he is bord and needs a project. if any thing it gives you the ability to say i have a twin turbo civic.
i wonder if a quad turbo with four motorcycle turbos would be posible. mbay not enough room

Re: Twin Turbo D16. I need a project
 

abaz's setup was pretty nice, whiteys was kinda all over the place w/ that manifold.

Re: Twin Turbo D16. I need a project
 

Been there, done that, not worth it. Although I'm still glad I did it.

Re: Twin Turbo D16. I need a project
 

What's the count up to now Whitey?

last time I checked, there were at least 14 people who have tried to claim credit for your setup on the web.

Re: Twin Turbo D16. I need a project
 

haha thats lame

Re: Twin Turbo D16. I need a project
 

Yeah Im not doing it because its "worth it"

I know some single setups would beat it

What Im asking is would it be good for the street sleeper I posted about in the first post. I want a stoplight racer that would make boost early, hook up and run

Would one smaller ball bearing turbo do that much easier? Or would 2 ihi's or kkk's spool even faster without kealing over?

Re: Twin Turbo D16. I need a project
 

wouldnt it be better to have it spool at 5000 rpms and have the wheels break loose than spining them from the start. thats just my preferance. but i think the twin turbo will work it is still going to build boost and it will be pimp


just do it

Re: Twin Turbo D16. I need a project
 

I dont like the feeling of having to wait for the power, this car is a daily drive and I usually dont downshift from 4th or 5th and just kinda touch the gas and the cars a dog

I want something that will have power there

Maybe a single ball bearing gt28rs with a smaller trim would be good

But Id like to make a twin turbo work, need info on spool times and boost regulation though

Re: Twin Turbo D16. I need a project
 

ive thought about doing one kinda like the the newer cat engines and that cummins twin kit with the one really small turbo for hella low rpms then the bigger turbo to take over at high rpms. im more of a hook up and go kinda guy but for what i do with the car, aka little to now racing, its fun as hell to slam through gears flarin the tires damn near to 5th gear

Re: Twin Turbo D16. I need a project
 

Go all out and stage them in series. Who on the site has a 40+PSI car? That would be badass. Streetable...pobably not but badass. Just a thought.

Re: Twin Turbo D16. I need a project
 

The motor just has pistons and rods and some head work

Not going to to be seeing anything close to 40psi lol

Running a small and a large turbo is no in the question, thats defientely a pointless setup that is to complex for what Im looking for

Im looking for a stop light racer

Re: Twin Turbo D16. I need a project
 

do two t25s and call it a day.

i know two of the noobs on here asked should we use them and are now trying to sell them .. shoot some low balls and get on it

Re: Twin Turbo D16. I need a project
 

ball bearing or nitrous ftw

Re: Twin Turbo D16. I need a project
 

I think jeffs TT LS-vtec was one of the fastest cars ive been in :y Id say its worth it just to see the looks on other peoples faces when u tell them u have a TT HONDUH :6

Re: Twin Turbo D16. I need a project
 

From the video I seen it didnt seem to pull through the gears like I thought it would

What turbos would I use and how fast do you think id be seeing boost? Or would one ball bearing turbo with short intercooler piping be best?

Twin turbo to me is yeah, just different and knowone around here has it, theres only one other turbo honda and hes running an SSAC kit with an FMU

Re: Twin Turbo D16. I need a project
 

been done like 3- 4years ago theres breif pics in the HMTJOINT vid ---- looks raw but was kinda weak O0

Re: Twin Turbo D16. I need a project
 

Would it not spool very fast though? And would it be beneficial to run 2 smaler turbos to make more power>

I dont know how small IHI or KKK's are

I need some opinions on how to make this idea work

Re: Twin Turbo D16. I need a project
 

as for KKK my buddy used VAG K03 and he made on DOHC D series 155HP/185Nm at 8PSI so this thing is REALY small

Re: Twin Turbo D16. I need a project
 

No. You get faster spool with a single.

Re: Twin Turbo D16. I need a project
 

^^^^ just look at supras for example. to get the most power with faster spool time. most supra owners go single

Re: Twin Turbo D16. I need a project
 

But a single IHI would dog out probably before 5000 rpm wouldnt it? Would 2 not support a better top end?

What was your car like Whitey? Was it ever running at a descent boost level. id like to run 15-17psi, dont know how to manage that yet either reliably

Re: Twin Turbo D16. I need a project
 

Two small turbos will spool faster depending on the intended application. Keep in mind you would be dividing the amount of exhaust flow/output by two. If the a/r and frame size are too large for the exhaust output from two cylinders, spool up time would be much slower than a single. Thus running two turbos improperly sized, you would be shooting yourself in the foot.

If one were to divide the ex. flow rate by two at a given r.p.m. (3500 for example), and one were to run run two turbos with a/rs comparable to a larger turbo with a 2:1 scale a/r, the twins would spool faster due to less inertial mass in theory.

It really comes down to turbo sizing and compressor flow rates.

Re: Twin Turbo D16. I need a project
 

Well Im intersted in making power quick, and trying to hold 15psi to redline

Throw me a turbo that can do that but be spun by only 2 cylinders

Re: Twin Turbo D16. I need a project
 

I'd say if you're going to try it, go with the KKK's from a turbo diesel. They should have a smaller exhaust wheel to spool up fast, especially since most older diesel engines don't see over 4500rpm or so. I used a KKK from a mercedes turbo-diesel, and with all the timing and cam timing set properly, it started spooling at the 1800rpm mark on my 1.6 liter :S

Re: Twin Turbo D16. I need a project
 

yes, whitey did the d16a6 tt with direct port nitrous.

abaz did a twin ihi's on a ls.

get it right you fucken noobs

Re: Twin Turbo D16. I need a project
 

Okay ---> http://www.turbobygarrett.com/turbob...4_454083_2.htm

In a twin set-up, if you stage the turbos in paralell, the sum of the two compressor flow rates will be enough to feed the engine and not choke off at higher r.p.m.s

There are many others capable of boosting low and flowing enough to make 15 psi to redline. Go to Garrett's website and check out their small frame turbos. http://www.turbobygarrett.com/turbob...ch_center.html
