My 2jzge-t swap

this is a badass thread. congratulations on your swap. you almost gave the illusion of it being easy.
just to clarify, you mounted this with MA70 mounts and JZA70 brackets? so it's virtually a bolt-in then?
good job!

yep. any suggestions with that? i want to run 14psi max, 10 for now. i have 550's, vpc, afpr, safc2, 57trim t04e, big greddy fmic, wideband, progressive methanol control. i just listed those mods so you know what i'm working with.

i used jza70 brackets, normal urethane 7m lower mounts, and a rear sump pan, and a bellhousing... nothing more. the trick is, almost everything else has to be modified. power steering, ic piping (in my case), wiring, fuel lines, alternator, cps, upper radiator hose. other than that stuff, yep, bolt in.

one time deal :biglaugh: i got lucky with that one, because he bailed my ass out.
Traction will be limited above 10psi At 15psi my rear tires(275s) don't grip until I hit 3rd :evil:

I wouldn't recommend skewing the timing using your base timing unless it's a last resort. There are other ways to do it even with a piggyback setup that has no timing control.
I can elaborate on this if you need me to^
What size HG are you running?
On my car, I was running what I considered very aggressive timing, I went to the dyno and made 450whp... I couldn't believe it. I grew a pair and went back two days later, positive that the car was in 100% mechanically and there were no physical restrictions. I added about 2-4* of timing to the ignition, map in select places, and made 677whp at less boost
.What size nozzle are you using with your methanol injection? The reason I ask is because I've heard of people running methanol and losing power vs the same boost level on 110 leaded. They were on the stock ECU, they weren't running any crazy setup that would make me think they were detonating forcing the ECU to pull timing. Methanol will not kill power if tuned correctly..
The previous story, plus my experience tuning methanol, and some of my research done on the Buick Grand National forums all lead me to believe that if you're running enough methanol, there is a chance even the stock ECU may not be able to give you enough timing.

i'm running the stock hg for now, i do realize that this is going to hold me back. hence i want to only run about 1 bar. my safc at 7psi and 5 degrees of base timing is registering 180-190 knock but i know its very brief. i also know its happening around the higher rpm. also at other times my knock at the same boost is 26 or so. afr's are around 12.4, i guess i could add some more fuel. i believe my methanol nozzle is 440cc's i have a bigger one but its only recommended for 600hp. oh well, guess, i'll just go to 10psi for now. i guess not too much bad stuff can happen from just a 3psi boost increase except for more tire destruction, 2nd gear has problems even at 7.
so, i tried 12psi tonight with the methanol too. my safc shows a knock the very millisecond i floor it, and then it never comes back. the turbo has almost zero lag, and it feels almost like i'm being rearended when i punch it. my new problem is my spark is being blown out, i know this is what it is. i've had this problem on other cars i've owned in the past. my gap is at .026 so, i guess i'll go a little tighter, if that doesnt work. new wires. but i smell a cop conversion coming...
Ahh, the stock HG.
Honestly, since you're running a 7MGTE ECU I don't think you need to retard your base timing more than a couple degrees.
From what I'm told, using the stock knock sensors with the SAFC is not going to give you a good indication of knock. Are you getting repeatable reading?

yep, or less boost :cry:

yeah, the readings are happening over and over again. its always like 190 or so right at the moment i floor it. and yes, the head gasket is stock. i'm still at 5 degrees btdc. honestly, if i add any more power, i dont know if i'll be able to put it down without my mickey thompsons. but when i get bored of this power, i'll probably go advance it to like 6 or 7 btdc. because i dont know if this ignition is going to cope with any more boost. i'm going to try a .022 gap today... lets hope that works.

ngk iridums 1 step colder, stock 7m coils, acura legend wires. i gapped the plugs down to .022 and that fixed the missing from what i can tell. i know it can make more power at this boost. so, i'm going to tune it a little more. so, you think i can run more timing? i'm nervous about running more timing because of the compression ratio on this engine...
new video... same as before. 60-120 pull starting at 60 in 3rd gear. about 13psi of boost, 5degrees of base timing, w/ methanol (green light in video)
