The only way to change the injector size is to enlarge the nozzle diameter.
The perfect match for the rx8 yellow injectors is a 3mm dia. nozzle
Let's say that there is no huge power difference between gasoline and propane, but my setup is really basic. To have the benefits of pure propane I need another lpg ecu like the brc sequent, emmegas, or even the icom liquid injection (they guarantee more power even with stock engine, and it's green )
Oh man this thread is entertainment. Thanks for all the pics. You know you are doing some interesting things with the arduino. Im surprised you are not developing things and selling them on here to fund your build. Which also led me to wonder why you didnt build your own MS. Nonethless thank you for all the work you have done here. This thread is very enjoyable. How much longer do you think the ebay manifold will last?
talking about the ms2, I simply followed the advice, most (all) of you told me to buy rev's ms2... but I was fully satisfied: it is really a great product.
BTW
the ebay manifold have to last at least one mounth, because I plan to build it stronger
Pictures time!!
from the left: table - launch/flatshift - valet - high/low boost
the reason I put a valet switch is because I'm planning to build the engine, and for the first 1000 km the valet will be on
from 2" to 3"
downpipe is 2.75 to 3"
in this photo the exhaust seems too low, but is upper than the chassis
result: full boost at 3500 rpm (10 psi)
safe advance table:

Not really..
What was happening: casual spikes on rpm signal and boost (psi) but not on map (kpa)
That was strange, in fact I saw casual duty rises without evident reason, only after checking every single parameter on megalog I found that boost psi has the same spikes as injector duty.
Sometimes, during hard driving, expecially coming out from a corner at high revs and then wot, the battery light turned on (sometimes flashing) but with constant 14V with no spikes ever.
Sometimes the engine died with that light on, and if I do a power cycle (turning off and on the key) all disappears and the engine ran well.
I thought that the problem was bad grounds, and I rerouted the main one.
I don't know where the other ecu ground is ( from ecu gnd to chassis) but since I rerouted the main one the problem seems to be vanished

watch the knock in:
I was tuning ebc in cl (lots to do), the battery light turned on with no reason (14 volts) and during the next pull (screened) the alternator died (darker lights), if I accelerated it misfired like with launch on and clutch depressed and tunerstudio said "offline"...
turning the key off and on again (ecu reset???) resurrected the car -.-'

the only thing I've done with the emanage blue was connect the knock sensor to a portable guitar amplifier and listen with headphones, and I could hear knock rising the advance from software...

det cans.
the bp is a rough/noisy engine so I wouldn't be surprised it's picking up random noise, or perhaps it's just set too sensitive, but I would find out before you push this thing
*edit: and you've obviously have an electrical issue too if you're pegging it like crazy on that last pull

Tonight I will do another log to see if there anyways spikes or not

last log, around five minutes before buoooo CHUFF rattle rattle rattle
and the advance table I was tuning
I tried to set the advance to 26 degrees at 4500 rpm and 170 kPa to see if the oem knock sensor works, and... yes, it detected the knock and pulled 2 degrees. Obviously it lasted maybe half of a second, it was just a test.
The windows were open at 6000 rpm btw

you have:
new main bearing
ebay rods
new piston ring set
oem head gasket
supertech valve seals
8 spare 10:1 oem pistons in good condition
another block
another oil pan
lots of stuff from 3 BP's
your goal is 250-275 whp on the road
do you:
-wait two months and build with be oil pump and supertech 8.8's overbore (because money)
-istantbuild with oem pump, rev limiter to 7000 and oem pistons
are oem pistons good enough to handle 250 whp on the road, and maybe two trackdays a year?

if oem pistons are really good for 300hp, I can simply limit the power down of a certain limit
in sardinia 250 whp are, how can I tell... interesting
and I want the car back in no time
