Hi guys,

a freind of mine have just removed a turbo kit (Greedy turbo, Trust intercooler, ecu, pipes, waste gate, exhaust manifold) because he is selling the car.
This kit was installed on a civic 1998 d15 engine.
Can i install it on my b16 (civic si 00)??
He is asking for USD 1500 and is that a good price?

Thanks for your help

 

you will need a new manifold and downpipe the rest should work. also will need to have it tuned. even if it comes with the blue box that will be for a single cam not a dual cam

 

thanks man for the info.
BTW can i run 7 psi on stock engine?
My goal is to reach about 230 hp, will a boost of 7 psi achieve this hp goal?

thx

 

dont be concerned with boost pressure just aim for your goal. Im not sure what turbo comes in that kit but you can reach 230hp no problem on stock engine just be sure you get it tuned dont drive it around without a tune and a basemap isnt a tune

 

Hi again,

I have spent several hours reading atricles to understand the concept of tuning and avoid the below question but i got really lost!

Once i take my car to a tune shop, i would like to have a full idea on the process that will be done.

So now there is the stock ECU and base map that came witht he turbo.. how thing will be working now?
will he tune my ECU using an already set map or what?

Thank u

 

I don't think you can retune the greddy blue box. Have you invested into hondata for your ecu?

 

In order to understand the process completely, you'll need to start understanding ignition and fuel timing in fuel injected engines. PGMFI.org should help, but it takes a very long time to master. Unfortunately, you more than likely will not be able to monitor or dictate his abilities to adjust for fuel trims and timing while on the dyno. If he has a good reputation and does well, there is not much you could tell him even if you did study these systems

As for the turbocharger, the GReddy D-series kits used a 15G turbocharger capable of about 36lbs/min, about 220whp or so, but that is really pushed to over 20psi of boost pressure to do so. That also means that you would need to change wastegate actuators in order to do so, as the one that came in the kit is not capable of over 20psi. The new manifold that you purchase need to be of a T25 flanging system, and not that a standard T3. That would need to be made.

The "blue box" for the 15G (depending upon year) was not reprogrammable. Neither you nor the tuner wouldn't be able to change most of the programming in it anyway.

I'd honestly try for another approach with new equipment for your goal.

 

That little 15G regularly makes 200-210whp on far less volumetricley efficient D-series motors at less than 12psi, I think he'll safely be at 230whp with no more than 10-11psi on a B16.

 

I doubt that very seriously. We've tested the B16 on that 15G turbocharger for a number of years, for true accuracy, it was over 16-18psi of actual pressure to get what he's asking. At 36lbs/min, 10psi is NOTHING for a B16. Even with the appropriate intercooler, though he'll come close.

 

+1
16 psi was the most i could get with my rebuilt 15g.
that was with new actuator and a spring from a screen door holding it shut.
its beyond its efficiency by then, making more heat than boost.

 

I don't.

If a used TD04-15G could make 217whp @ ~11psi on a, relativity speaking, highly inefficient D16Y8, and another 226whp @ ~11psi on an arguable less efficient D16Z6, I can't see why it wouldn't be able to support 230whp at 10 +/- 2psi on an engine/head with a far greater ability to move volume like the PR3. The math just isn't there. I don't argue that it would be an incredibly inefficient if not virtually ineffective turbocharger at levels higher than 15psi without the aid of meth or some other thermal modifier, but that wasn't the point.

 

Its not just about the math. its about the idea that running turbocharger for over that amount at under 68% efficiency doesn't make sense. Especially with the amount of work that the OP would have to perform in order to integrate such an inefficient turbo on a much more inefficient engine package such as the B16.

The OP can do what he wants. i'm not going to have an opinion anymore than this. But it really doesn't make much sense.

But, whatever, hopefully he'll have better luck.

 

Got some real numbers.
Greddy 15g max out at 23 psi
Several D series engines are making between 200 and 230 hp with a boost range of 8 and 12 psi
It is really confusinggg!!

Just a small comparison, dunno if im right to think this way:

d16y8 is 127 hp
with 15G turbo boosted at 10 psi it made 210hp
which is additional 83 hp

b16 is 160 hp
all i need is additional 70 hp, so why this turbo cant get me this power! which is less than what was made to d16 engine !

 

I'd have to agree 100%, for the sheer amount of work involved in mating a B-series manifold to such a small T25 based turbine inlet and running the associated hardware, frankly I don't know why anyone would go through the effort for such minimal gains.

As they say, you can lead a horse to water.....

 

I think you might be missing the bigger picture here. While I do believe a 15G will produce 230whp on a B16, it's a matter of efficiency, or rather a lack of. The little TD04 was chosen by GReddy for the D-series for it's ability to complement the engines natural tendencies, lower rev range, flatter torque curve, very much a mismatch for a high rpm/peaky motor like the B16. For the effort and expense of finding a T25 flanged B-series manifold and having the rest of the hardware adapted to your car, well, you probably could've found yourself a nice 18G B-series kit and be ready to bolt it right up. Just my .02

P.S. the examples I used were both my own Civic ('98 EX coupe, 217whp @ 11psi), and a close friends Civic ('95 Si hatch, 226 @ 11 or 12psi), both ran on GReddy TD04H kits and were all kinds of fun to drive, but there's nothing like a screaming 'B'. Good luck!

 

yes, the 15g is kind of small for a d16, boost starts falling off around 6800 rpm.
funny thing though, Greddy did offer a 15g kit for b16's.
my friend had one on his em1.
he only saw about 6-7psi, with greddy's eManage, no idea how much power it made

 

Hey guys first time posting trying to look more info up but getting stuck. I just bought an eBay turbo kit from DNA motoring , speed daddy... The turbo I got was a t04e 48 trim with external waste gate , front mount... I'll be finished installing the mismatched kit in 2 days now my question is on what supporting mods do I need if this is on a 2000 Honda civic si b16 a2 vtec engine. I have dsm injectors, I don't mind buying a walbro fuel pump, don't mind getting the car tuned... Or do I just take car stock to get tuned? I found a rewrite up on a d series turo install but not on a b series... Anyone got one so I can read options I got?

 

They offered the 18G for all B-series VTEC engines. All the d-series received the 15G variant.

 

HI and welcome. please check the FAQs (highlighted in grey) at the top of the forum. they have links that have direct answers to those particular questions, including your decision to get an "eBay kit"..

Thanks for coming by. Its best to start your own thread as opposed to attaching to this one.

 

The 15g will not be very efficient on a B-series motor. Howevere it will spool quick.
