I'd rather have a proper map than rely on the j&s to rein it in for me. The whole idea behind the system is that you should NEVER need it...

yes, any engine management should have efficient and knock free fuel and ignition maps.
however, the j and s does exactly what its name is, its a safeguard. you cannot tune for a bad injector, for bad fuel, or any other system that may fail while pushing the engine. if he is running methanol without a failsafe, then any fault in the methanol system could cause serious damage to the engine (i.e. meth stops spraying, clogged nozzle, power failure, etc). The j and s could potentially save the engine.
I agree, the safeguard is not 100% necessary. However, the j and s is in there for peace of mind and as a preventative measure in case something does go wrong.
Mazdaspeed2oo35- don't kill yourself trying to find one. its not the end of the world if you dont... the next best thing is the knock light. no it wont retard the timing, but you will immediately know if something is wrong.
well with the power level that is planned for this engine. His window of safe tuning vs destruction is going to be very small. I would be losing sleep over the j&s myself. Shoot, I am already starting to think about it each night in bed. lol
seriously though, what's so hard about getting one? Their basic units should work just fine for your set up. Even though it's not specific to your model, that shouldnt be an issue.... I was just on their website, and it looks like nothing has changed. Have I missed something?
edit: are you running a sequential injection set up? Our engines are batch fire, so individual cylinder control shouldn't be so important.. just a thought..
And, if I had the J&S last spring. It would have saved my engine from it's current failure. An injector rail bolt worked loose, and hopped the #4 injector off the intake manifold at 24.7psi. I'm sure I wouldn't have lost that cylinder if I had the j&s when it happened...

Not much of an update but well something is something... I went and picked up the head from the Machine shop, came back in perfect shape and ready to be installed, also ordered the TurboXS Knock Light with TurboXS Bosch Knock Sensor i hope if comes this week so i can install everything at once and start tunning the car

wow thats beautiful. is that a custom head? whats been done to it?
the problem is the protege's coil packs have a built in igniter, which calls for special electronic controls for them... thats why other aftermarket ignition upgrades like MSD don't work with them... thats why you need a protege specific J&S for it to work on the protegewell with the power level that is planned for this engine.

all I have to say is to keep an eye out for a used one and jump on it when you can... I saw some here months ago
funny how nobody cared about them until its too late once they found out how good they are... the reason why its not made anymore isn't due to poor sales but the lack of parts to do so... the chips that were used are no longer made and john has to port code to a different sourced ones and guess which cars gets the priority? the ones that sold well! given time and hope, we may see the vampire version for the protege come out but don't hold your breath
is that head your original factory one? I don't think it should say "FS2" on it!Not much of an update but well something is something...

600whp - 600wtq at 30 PSI
The pistons are Custom Wossner Hi Performance in 8.0:1 low compression with Special coating done to resist more temperature and higher boost. i paid in total with shipping and coating
€ 900 Euros, straight from Germany, thats around $ 1,305 and im still using my Previous Pauter rods which runs for $ 800 with ACL .25mm Tri-metal Racing Bearings and ARP main and head studs.

That's Actually a Custom built Stage 3 Head done by Hiboost & TBK Performance , the head my car came from factory was sold and this one came from outside USA, I don`t remember exactly from where but had to wait for it around 4 months, this head has Bigger Ferrea Titanium Valves, Double Valve Springs,Titanium Retainers, 5 Angle Valve Job, a Very Aggresive Port and Polish Job, Custom very aggressive Turbo Overhead Cams, ARP Head Studs, SR Motorsport Adjustable Cam Gears, Throttle body port and Polish to 60mm, Throttle Body Coolant bypass, Mazda 626 Intake Manifold with Single Runners with aggressive port and Polish Job. The secret and success of our engines is to have a fully built head they do such of a difference you wont believe.

in there you can see more pictures of the head when it was new, you can see the valves new and port and polish job done to it..

Bro i dont know all i know Hiboost and TBK Built that head for me and came from Outside USA dont ask me where but definitely not from USA, i think from Argentina or Colombia not sure tho, then they did all of the work to it, bigger valves, etc etc etc..

According to my tracking info i should receive my TurboXS Knock light along with Knock Sensor by Saturday this week, Jesus i can't wait to have all this installed and tune the car..

wow thats pretty extreme thanks
that's what I thought.... no big deal since its ported... if it wasn't you're screwed because it looks like an earlier FS-DE head which has smaller intake ports
you need to run more antifreeze in your cooling system... that rust is getting nasty! running straight water is stupid!

i'll remind you that i blew my head gasket and water got contaminated with oil and vise versa, I've never ran water in my car. Solid Anti-Freeze..

running either strait is stupid. anti-freeze doesn't transfer heat like water does... and water obviously leads to corrosion.... no water probably contributed to blowing the HG.
running 30% antifreeze/70% water mix seems to be the best in a warm climate
higher boiling point but still good thermal capacity of straight water
add some redline diesel water wetter in there to reduce cavitation and increase heat transfer abilities... run a high pressure radiator cap and a low temp thermostat to help further reduce cavitation and increase coolant flow and boiling point

then why are all the water galleries all rusty looking?

isn't that something they typically clean up when a head is machined? at least a good shop anyway...
I got a block disassembled at a shop and it came back all cleaned up...
