just from glancing at the list it seems like the most reliable option is the jrsc with jr ems/fmu.... i hate to sound clueless but what does ems and fmu stand for?

I speak fluent typo
that's what the JRSC comes with - EMS = "engine management system," which is basically a black box that retards timing and spoofs the map sensor and intake air temperature sensor readings. fmu is fuel management unit, it's a rising rate FPR.

Ran 6psi daily, not driving it to hard. Ran 12-15psi a couple times (Say 5-6 runs) which I feel weaked my motor pretty badly. I was tuning with a Vortech SFMU and a VAFC using a friends Lambda meter so I wasn't running too lean.
It blew up on a 4th gear 6psi run. She lasted 6 months of abuse though, more than I would have expected because of all the high boost runs.
All fixed now though, 1300 miles on new piston and going strong.
ok, now that this thread has been going on for so long.... somone list some things that should be bought with the jrsc kit to ensure that you won't blow your engine. I'm planning on doing this and i figure i might as well spend the money to do it right so i don't have to rebuild my motor.

There is no consensus yet. Several people have tried different things. Results are slowly coming in.
chomorro's approach (nice results, but not ran long, uninstalled to go turbo):
Add me to the non blown list (knock-knock).
JRSC @6psi jr ems/fmu. 10 months and 15,000 miles of fairlly aggressive driving consisting of the occasional couple gallons of 110 for the track (x4), a 150+ mph run with an M3, and the constant messing around on the streets.
A recent compression test checked good. I also flushed the radiator and added 70/30/watter wetter. Also got colder plugs gapped to .032. VPAC's at 3500rpm and BTC's at 3 from min. No detonation.

man this sucks. i have an f-max kit falling into my lap, with a bigger fmic, basically for free. im spraying a 75 shot right now but a turbo will be much more fun... but now what?? i dont have money to build my engine, i dont have money for a hondata... what do i do? ive got 70k miles on my 93 VTEC...

bleh
Don't up the boost above 7psi, make sure you've got good tuning. And then between now and 6 months from now, save your money for a built motor.
just to clear this up, i had no FMU inplace after the install. So my first good run or so sucked. I took it back and they 'tested it'. unplugged the 'wastegate' because they 'couldnt find out why it wouldnt boost higher' and took it for a 10psi ring busting, moment. patched me all up and sent me him ... to post here to find out i had busted rings. just for the record
MOTORSPORT TECHNIQUE =
and for some more clarity, i busted 3 rings into atleast 3 or more pieces.
4gen here.
Prelude Si, 6-7 psi daily.
been to 10psi a few times.
never any detonation.
no problems.
*BUT I real curious on any precautions or warning signs for blown ring lands!

BluLuder: what you have to look for is smoke coming out of the valve cover breather. But to have an accurate assessment of your stock internals shape, just do a compression test.
I just blew rings in cylinders 3-4 smoking like a frieght train.
175 in 1-2 and 100 on 3-4 on the compression test.
I'am running a stock motor with a T04e T-72 compressor wheel and p-trim turbine wheel with .70a/r .... custom kit and 3in. exhaust turbo back.
fuel....I'am running 450cc injectors with resister box....Aem fuel rail vdo press gauge and walbro 255l high press pump.

rebuilding motor this weekend, new rings, Cometic head gasket to drop compression to 9.0:1
then I will boost no more than 15, an 18 once in a while. By time I break something my serious motor should here.
...................That I will explain in my next post................................
What boost levels were you running before the ringlands blew?

What do you guys mean by ring lands blowing. A ring is a ring and the land is what the rings rest on. So when you guys say ring lands are you referring to actually breaking the lands off the pistons.
I was about at 10psi untuned when this occured, and I detonated pretty bad. blew flams out the exaust. everyone traveling behind me quickly moved.
My car is blowing out clouds of white smoke through the exhaust and the breather, however the smoke doesnt have a blue tint to it so I'am thinking I must be burning some water as well.
My car runs smooth without a hickup at all and idles good and no vibrations what so ever from the motor, I can put my hnd on the valve cover and no shakes it purrs even when reved. So what the hell is going on, answers anybody
If not for the compression test and the smoke show no one would see anything wrong. And I cant drive it cause if I make a smoke show, in my rearview I'am sure to see a light show.
My antifreeze is still green and is full in the radiator so I dont think I cracked the block. My only hope is that I didnt score the cylinders to bad if the lands did break.
Well people please let me know what you think on this subject thanx!!!!

Add me to the list. I've been supercharged for 3 months and 6k miles. I compression checked the car last week and it was 205, 200, 205, 205. Right now I'm running the basic setup with a VAFC to richen in the midrange and top end. Getting ready to add Hondata 2b, 440cc injectors, and P28 ECU.
