whats up fellas its been a while since I have posted. Hope everyone out there is good. So I'm trying to finish up some last few things before I go to the dyno again. So I am fully gonna run through the fuel system and install new PHR triple pump hanger with 2 450's and 1 525 walbro pumps then out to a -10 line from pump to external stainless fuel filter then split to 2 -8 lines to radium fuel rail then out the 2200cc Bosch injectors then two -8 return lines out to FPR then 1 -8 return. So my fuel is well up to par but now I feel I'm gonna be lacking in spark since I only have factory vvti coils. I'm thinking of going with r35 gtr coils. I've been told that they are good to well over 1000hp. It might be over kill for my current set up but I have always lived by i would rather have more than not enough plus im planing on getting more power later so its better to do it now IMHO. Are there any kits that u guy can recommend? Now for the Aristo 4 speed trans. I wanted to know if anybody knew how much they could handle with a valve body job and torque converter. I know factory can only handle about 500hp. I just want to have this trans until I figure out what trans I'm gonna build and I want more than 500hp. Thanks in advance

I just installed an 800whp rated A650e from Powerdynamix. It is probably your best bet if you are going for big horse power. OEM 5 speed that is made for the car and plug and play rather than a weaker 4 speed that the ecm/tcm isn't even compatible with. $2Gs well worth it if you ask me. I am working towards 700-800whp and still plan to run the three factory coil system, (though they are NGK replacements). There really isn't much negative to the output of spark IMO. Also because of the intake/throttle placement of the GE this is not very feasible if you don't have a GTE because you'd have a very hard time fitting the individual coil setup with the required adapter plate under the GE intake system. I did upgrade to some Magnacore 8.5mm wires though to help out in my case. I also tried to get a converter from PI (Precision Industries) but it doesn't fit. They did restall the OEM one to 3200 for me for $250. So you might look into that. That's the things I did that relate to your questions. Not sure what your setup is, but I'd be happy to help you in any what I can. Curious about the two 450 and one 525 pump choice though? I am running one 525 with a 8an feed and 6an return and that will be sufficient for 800whp on pump gas with 1150cc injectors. What the heck kind of power level are you trying to achieve?

Sorry if I didn't go to much i to detail before I have a 2jzgte vvti swap with the button shifters integrated in so that is working on my 98 gs300. Thats why I have the 4speed trans which would be the same trans on an automatic supra. No NA-T here lol. Currently have a borg s366 billlet with .96 back housing. Planing on getting a 7675 ball bearing tho soon. As of right now stock trans and stock diff to go along with the fuel system i said earlier. Aem infinity with all sensors

Nice I'm running an AEM Infinity with their sensors too. You could still give Jeff at Powerdynamix a call. The are crazy about these cars and do custom builds on the 4 and 5 speed transmission, turbo kits, etc. All for these cars. They can build you a trans capable of what you need.
