1jz turbo upgrade opinion

[MetaL]

Feel kind of stupid to post this thread but the search came up emtpy on what i wanted to know. I was wondering if anyone here is running a T67 dbb or a T71 dbb turbo on a 1jz with a ported head and cams. I'm mainly asking because I am coming up empty handed on compressor maps for either of these two turbos since I am very worried about surging with a T71. My aim is at least 600rwhp and i know a t67 dbb has done this on high boost. I was just curious if anyone has done a T71 dbb on a 1jz and if it surges. Thanks.

I haven't had any issues before. My car isn't on the road right now due to some engine work but by turbo is a .70 A/R and haven't had any problems in the past.

I'm running a 65mm turbo.. drives just fine.

If you want a solid 600whp without crazy boost, you'll need at least a 67mm. If you got the flow, get a GT4067R. If you dont, get a ITS GT67.

If you want to try and do it on pump gas, check out the PT72GTS

gt4067r would be a great turbo hands down, I was looking at that turbo vs a gt4088 just haven't found a compressor map for the gt4067r either lol

GT4067R is one of the most famous turbos to be ever put on a 2JZGTE. It works just as great on a 1JZGTE.

530whp being conservitive with the boost

11.6 1/4mi letting off

He wanted 800whp, so he did this

These are all MTR sponsored cars. This doesn't reflect what he built that is unsponsored. Miami is ballin'

The GT4067r is a hybrid turbo.
