Im looking to get a SC either the New Vortech of the JR. If I get the JR I want to go 8psi right out of the box. What would I need to make the car a daily driver and running fast?
pulley
j&s safeguard
dual monitor round guage
Btc
Injectors?
cartech FPR
Fuel pressure guage? which one?
oil pressure
Boost pressure
What else? I hope I have a good idea of what I need but will it be hard to tune? Any/all info will be a great help???
thanks

pulley ----YES
j&s safeguard ----YOU CAN GET AWAY WITHOUT ONE WITH CONSERVATIVE TUNING.
dual monitor round guage ----DITTO
Btc ----DITTO
Injectors? ----DITTO (if you don't mind 100+psi fuel pressures and get a HO fuel pump)
cartech FPR ----YES
Fuel pressure guage? ----YES
which one? ----Full sweep Autometer. Pay the price and you'll be happy you did.
oil pressure -----NOT NEEDED
Boost pressure -----YES
<<What else?>>
-A/F Ratio gauge or EGT Gauge.
-HO Fuel Pump

Holden: quick question. I asked my mechanic about installing a fuel pressure gauge and he said it was a bad idea to run the fuel to the inside of the cockpit of the car for the guage. So my question(s) [heh] are is he right and if so isn't there some under the hood (in-line gauges) you can get?
Thanks

Ooppss. Also forgot to ask if
1) how bad it is too run 80-90psi on stock injectors vs. the normal stock pressure of 30-45psi(is that right)? How long will the stock injectors last at that increased pressure/how much life span shortening to expect?
2) where can I find out how large my injectors are on my 99 Prelude. I looked all over the web but it doesn't seem like anyone hardly sells replacement OEM injectors AND indicate the size of them. Could I just easily call HOnda parts during the week?
Thanks again

The fuel pressure guage is ok to use...you dont run the fuel line into the car...instead it uses a electrical sender that mounts in the fuel line under the hood...and a wire runs to the guage inside the car

With the Autometer full sweep electrical guage you don't run fuel in the car. There is an electrical sending unit instead. You should never run fuel in the car BTW!

I think peak pressures of 80-90psi are fine. It's when you go over 100psi that I'd start to worry.
To find out what injectors you have, send them to RC for cleaning and balancing and they'll measure them exactly.

I believe the earlier H22A engines (93-95?) used 340cc injectors. I think they have since downsized the injectors to 290-310 but I am not positive.
I wonder if the size of the injectors is stated in the Helms manual.

Thanks for the info! Im still waiting for info in the Vortech from one of my buddies. Do you think the 8psi JR will be hard to tune?
thanks again

As for the J&S... I have not tested a new design yet, however, I understand that it now comes with some type of boost sensitive retard capabilities. As for having a re-mapped timing curve... unless John has tested a Jackson powered GSR or Civic, I do not see how his curves could be optimized for this application like the BTC is. In any event, John makes an excellent product and his continual advancement of the piece is commendable.

Jim, John just announced the new feature a few days ago. With the proper inexpensive testing equipment it's easy to replicate the timing curves of the BTC. By utilizing a microcontroller in the J&S unit, makes adding new features very easy. Especially, with the abundance of I/O's in the Motorola controller they're using. I'm not implying J&S tested the BTC, but I think J&S will be offering a BTC "like" feature of the new safeguard. Here's the link: http://www.hostboard.com/ubb/Forum40/HTML/005228.html
scroll to the bottom of the post.
Here's a direct quote:
New feature just added!
In addition to knock retard and boost retard, the unit recurves the Honda ECU timing. The system advances and retards as much as 8? in the mid range, depending on RPM and vacuum. This should kill any part throttle detonation, while still allowing you to run full stock timing.
