Someone has to keep it alive.

 

Damn, up from the dead. I am looking at getting a SOHC kit for my stock D15B7. Yeah yeah yeah, I know. I am not looking for high HP, just a little fun. I have no plans to swap my sohc unless it blows.

What is a good choice of injectors? Anyone prefer a setup within the chipped P06?

What other mods are recommended besides the I/H/E as I have a Mugen EG9 twin loop I AM NOT cutting what-so-ever!

I know I should read the thread....and I will. Expect this post to be edited with more questions.

 

Either find a used JRSC for D16z6 and may have modify a little, or make a kit.

I made my own kit using a SC14 (1.4L/rev) off of '95 to '97 Previa.

Cost me about $600 on first setup, and closer $1000 if you want better appearance under hood.

 

Pictures of your sc14 setup?

 

Here with mocking up my HE351ve on top of the SC14 for my Twincharge Setup.

 

Wow thats insane.

So I found a Z6 kit, and picking it up on Friday. I have a basically stock D15 in my Civic LX. What mods am I going to need to do to get the kit to work?? What means of tuning are you all using?? This is going to be a DD, SC'd for fun.

 

Anyone??

 

Im not much help with the d15 BUT

dont use the jackson tuning stuff its junk
aftermarket tuning like hondata is the way to go either s200 or s300
so you might need to get a new ecu
header with short primarys does help
good cold air without restrictions " blower dont have to work sucking air in"
hondata intake gasket will help with heat
gator back belts dont suffer with slip as much as others
1 heat range colder spark plugs

thats about all the help i can offer as I dont know enough about the d15

have you read the JRSC instructions yet they might help a bit

 

Hey guys ive reading alot on this thread and have searched for hours and cant really seem to get my answer. So im planning a nice fully built sc build but i cant seem to figure out what is the best gear ratio. Since the boost is constant is it better to have short gears to get up to speed or is it better to have longer gears like a turbo. I need help here, my last purchase is due which is a transmission so i need to figure what to get and quick! All help is greatly appriciated!

 

i made 190whp on my stock never open D15b7 non vtech stock pully just bisimoto headers and tune con chrome

 

92cxyd, are you going to use the nut/bolt system I see to control housing volume? The he351ve's vgt system technically should be vnt, since all the system does is control housing volume.

Fully closed it's 2cm and fully open it's 25cm, I'm afraid with a stationary volume you won't get the full benefit of the turbo, and if the housing is set too small you'll see excessively high back pressure, especially when twin charging.

It would he better to use an adjustable internal wastegate actuator on the vgt gear like a bunch of the DSM guys do, keeps the housing closed until a set boost point then it makes the housing larger to lower back pressure. With lower back pressure you'll see a power and mpg increase on the motor

And I'm referring to exhaust manifold back pressure, just so there's no confusion

I would suggest this method because even though it's only a sohc, you'll see such high back pressure that it will take a very large wastegate to control boost around 44mm or bigger.... an this is more so important because you're going to be using a log manifold.

This all being said because I have a new he351ve laying around and I'm debating on which setup to use it on, so I'm definitely in for results.

 

Now, if you keep the system like you have it, with a stopper to control how big the housing gets, when back pressure increases enough it will force the housing open but with no return spring on the vgt gear the housing won't return to its smallest size when back pressure decreases

 

Wow this thread went crazy.

 

I run the VGT on full (25ish cm2) for winter and DD w/o s/c engaged.

See boost from 3.5 to 8k (7-8psi) max. DD form

When I get to race I'll move the gate about to 18ish cm2 and get 15-16 psig @ 7k, w/o s/c engage.

With the gate set at largest size and s/c engage I have boost from 1k to 8.2k and 29-30 psig.

I've seen the different setups out there for the vgt and decided to go this route b/c of space.



As for the WG size I have a 50mm on there and need to get a second 1g DSM Bov, or get 51mm BOV instead.

The log manifold was for just getting it done and seeing what can get for boost.

A new custom top mount is in the works in the next couple of months and this give me more room to revisit the variable gate mechanism.

And by the way if you use a SC14 s/c, you do not have to have a bypass valve route turbocharged air around it when disengaged.

The s/c will just freespin since it is a roots style blower.

 

Badass!! Thanks for the help above....

Got my SC, and cleaned it up. The rotors look great, hardly any wear!

But I need a Chipped P06 ECU. Here is my setup.

1995 LX D15B7
OBD1
Jackson Racing Supercharger
310cc injectors
Golden Eagle Fuel rail, and Cam Gear.
Header with Authentic Mugen EG9 Twin Loop catback.
HKS Filter on generic intake piping
Stock internals.
No VTEC.

It's my DD. Just need a basic street tune basemap.

 

chipped will only make a mess of things you realy need hondata or similar
for good results and a safe tune

 

Hondata s300 is the only way to go. I hear the b7 motor make great hp numbers. You will want some bigger injectors than those 310's.

 

Crome Pro will work with that setup, 450cc inj. would be a better choice for your setup.

 

 

Hey guys so recently started a z6/y8 supercharged build and i just have a few question on what else i need. Besides gaskets and all those odds and ends. I have fully built bottom end low compression vitara set up, fully built crower head, and the jackson super charger. Im new to the motor building thing first go fast motor im building. I was just called out by a bone stock itr so i have to step it up and finish. Do i litterally bolt everything together and tune it? Or are there specific things i need before turning her over? All help would be greatly appreciated. Thanks alot!

 

You think? My car is just a DD. No track, no street racing. I work at a car dealership...so I have to keep a clean record. I just SC'd it for some fun.

I wouldnt mind going Hondata, but if I spend more money, it will be for a swap. This started out as a budget build cuz I got the JRSC for cheap.
