Did you do anything else besides pistons?
Do you have a larger fuel pump and bigger injectors installed now?

Unless you'll want to bore it to 75.5mm.
I have Crower rods and sleeves, titanum oversized valves and bushings.
All pullies, 4-1 headers dual exhaust and I polished the block and transmition
I don't have the pump and injectors yet.

Hector, how much was it to have your black sleeved??? I need that done to protect my investment and was just wondering how much it was and what company you bought the sleeves from??? Know of anybody in the Tampa area that can tune my ECU without me owning an E-manage or any kind of piggyback?

I like the Bosch Fuel Pumps you can get em for good prices, and are built to last, good quality product and will outflow a BBK 255 Pump all day long.... but venom makes a good pump as well... just not looking to spend that much on a pump right now...

I'm in the process of getting my kit from rscivic... these info really help me out alot... but I need more info about:
fuel injectors---by putting these on do I need to convert my returnless fuel system into return fuel system?
Will my ECU compensate with the larger fuel injectors with out any engine trouble?
Emanage or VAFC2---I have VAFC2 will these be fine with my turbo set up or do I have to get an emanage?
Can you guys provide me a Part# and or Website to get a direct replacement fuel injectors I wanna get a set before putting on my turbo kit...
any other initial prep prior to installing my turbo kit? I'm searching also but seems like it's all half *** info that I need...
thanks you guys!

Why are you upgrading to larger injectors? Is it a SF turbo system you are getting from rscivic, if so you don't need to upgrade the injectors, the SF fuel system is designed for the stock injectors (using a fuel pressure plate at a 12:1 ratio). I think something in the stock engine will give out before the stock injectors get max out by pushing more than 12-13 psi of boost.
If you do use larger injectors, the VAFC 2, can handle it by adding less fuel, but the e-manage is easier to program the injector change.
When are you getting your turbo kit? New/used?

^^^I'm getting rscivic's kit
I just thought of converting my fuel system into a return system i've seen some guys who did it... I fear detonation
but I thought of the theory: more gas and air=more whp!
I also seen opto trying to fit the RSX-S OEM injectors... no confirmation if it is a direct fit... opto isolator! help me!!!!!
So now I'm now searching on VAFC2 VS. EMANAGE sigh*** too much home work...

I am going to be installing RSX injectors too (they fit in, but need slightly longer bolts on manifold to secure it down), but I have a P&P head, TB & IM to install too, allowing for greater airflow.
Turbo - more pressurized air + Pressurized fuel = more Power.
If you have VAFC already, you can use it. Just start at low boost, and work up to higher boost (adjusting Vafc accordingly) when you are dyno tuning.

I took the time to read the Turbo FAQ on top of this forum.
ALL OF IT
I highly recomend reading it is long but is full of information and links to more info.
This will explain most of the basics and what to use.

They are a direct replacement. The only modification that is necessary is the mounting studs on the intake manifold spacer plate.......
u need to just extend the tabs on the fuel rail so it can bolt up
Quoted from here:
http://www.7thgencivic.com/forums/sh...4&page=1&pp=40
That is all the info I have, if you get any more please post it up, so we all can enjoy. I am also wondering exactly how much it needs to be extended?

An interesting qute from the E-manage support group in Yahoo talking about that maximum injector size the emaage can handle properly:
"Your math is off. I posted it before but in the wrong message. My friend runs 525cc on his SR20DE brain. The Stock injectors are 250cc, That guy prob has bad orings or dirty injectors.
Wael El-Dasher <wael.eldasher@aya.yale.edu> wrote:Actually it is only 50% larger, the 150% is only a marketing gimmick.
All I am trying to do is help. The guy is asking why is his car running
bad with 450cc injectors even though he used the injector change
table... and I told him because he has the wrong size injectors. GReddy
math is as follows... you take the stock injector, multiply it by 1.5
(150/100) and you have the maximum size.
He can run whatever injectors he likes but the compensation will not
work for beyond 1.5 times the size of stock. He will have to retune and
modify his map, put whatever resistors that will do the job...etc.
I am not trying to argue, he asked for a solution and I hold him to
return the 450cc and get 360cc. That's it, problem solved and why are
we debating all this anyway? He should pick up the phone and call a PSD
dealer (or more than one if necessary) and get the answer is a few
minutes!
I frankly don't understand why is there a big fuss and why I have to
prove anything. GReddy math is different from the rest of the world and
if they advertise that you can only run 50% larger injectors it won't
look as sexy as 150%, just like when all the Japanese shock companies
say stupid things like 16 way adjustable shocks...that is clearly a
marketing gimmick because there is no such thing as 16 way! They are 1
way adjustable with 16 steps, not 16 way. But 1 way adjustable doesn't
sound sexy. The emanage is very good computer but it's limited and it
can not simply control accurately injectors that much larger, which is
why it cost $300 not $1200 or more. It can not add more than 50% fuel
in the map tables....why?
The separation of marketing and engineering is blurry, but this is a
very good tool up to a limit. It can not replace a stand alone and
don't expect it to control injectors approximately 3 times the size of
stock.
I will use an example from the Support Tool manual. On page 26 it
explains simply.
"If the factory ECU injector duty cycle is 50%, and 30% was inputted in
this Additional Injection Map (which is a misnomer since the Additional
Injection Map increases factory fuel injectors)
50+ (50 x 0.3) = 65%" That means that 50% increase in duty cycle is
really only a 15% increase in fuel.
Using that example let's look at the fuel used.
a 240cc injector running at 100% is putting out 240cc of fuel correct?
Now if you add 50% more to the injector duty cycle...the max that you
can possible input in the table (even though the manual says you can
input 100% but it can't). Then you have the following
240cc + (240 x 0.5) = 360cc correct?
BUT, your injector is ALREADY AT 100%, adding 50% in the table is not
going to add any more fuel. So, you need a 120cc more
240+ 120 is 360
Which is also why GReddy say you can only run 150% larger injector, but
it's really only 50% larger.
Can you run a larger injector that 360cc? Sure, but you will have to do
more tuning and can not depend on the correction from the injector
change table and you are asking the computer to work at a resolution
much higher than it can handle, at that point you need a standalone.
