Default higher volume vs higher psi?

currently im at 338hp @ 9psi on a borg warner s362 .81 a/r turbine side pretty much stock everything. tuned via aem ems

what do you other guys that run single think about running a bigger higher flowing compressor wheel vs raising the boost?

getting a tt head gasket installed later and wanted to up it around maybe 15-17psi (i think thats safe on a tt headgasket on pump gas right? lol) with some 550 injectors and new fuel pump etc.


since its going to be all apart anyways i was thinking what if i swapped in one of the 66 wheels instead of the 62 for more flow.. but retain the smaller turbine side for spool time. not trying to max anything out so i doubt it will hinder top end

thoughts? will it be significantly more laggy?

cost isnt going to be an issue gonna be a hookup so thats not a factor.

15-17 psi on tt hg is more than safe .. im at 19psi pure pump gas and we saw zero knock .. my advice is get cams .. it will allow the head to breath and you would be surprised at 17 psi what kinda of power your car will make.. at 14 psi my car did just under 500 rwhp and at just touching 19 psi it did a easy 592

stay with .81 hotside .. ,68 is too small for a 2jz it will choke the turbo and create too much backpressure which adds wear to motor .. let it breath and get some cams

no sir very different .. you would have to remove your cams and send them to web cams to ave them reground after they cold weld them to the proper specs..

ge have the gear on ex side for dist pickup gte uses a sensor in the head to pick signal

I am getting mine done by these guys they are really good, and very reliable.
These guys charge $145.00 per cam, you can't beat their price.
Like ED said the cams will make it easier for you and i am glad to see you are running w/o any issues, and you didn't waste your time on stock 2jzge ecu and safc because it's garbage.

even if you don't need/want my cams hit me up. I have someone that needs his AEM tuned in his SC300. Wondering if your buddy is able to do it.
