Im running a blouch 18gxt currently on my v7 207 also tuned by matt from wicked. Im on my phone so cant copy and paste the link right now but you can look it up ej207 18gxt I believe I titled it. (Proven power bragging) Anyways... I made 362whp and 290 torque on a mustang. 22.9 psi I believe map is maxed at 23... could have made a bit more w map sensor and another psi or so... turbo could have handled it but just no need. I am planning on switching to the dom 1.5 at some point but only for a slightly better spool its not going to make more then probably 20hp at the same psi... but it should break me well over 300wtq as shown by matts bugeye. I am running decent timing but nothing insane his was more...93 octane also. Same dyno etc. Im at 23 psi by 4200 on the street maybe a hair more in 3rd. I have the v7 6 speed as well. My peak power is not until 7700rpm or so and barely starts to fall almost not at all by 8200. I was extremely impressed w the results w this turbo. It is an 18g..m but its 44lb a min 8cm hotside and 3inch inlet so more or less a 20g. Just another to consider I have fun w the v8s in my area

All depends on your goals. But it's definitely a proven awesome turbo. The 16gxt is to small. Mine is like perfect imo then if its any bigger id skip the 20g and go straight to the 1.5. The 1.5 is 49lb per mimute so it is capable of close to or 400hp on 93 as proven. But numbers are numbers. I can tell you right now that its not going to pull much harder then mine and like I saod make maybe 20 more hp but it will definitely make more torque and a bit earlier.

Heres mine. Definitely let us know what you do either way. My 18gxt setup was on my 205 and I switched it all over to the 207 its a huge difference between the motors w that turbo couldn't believe it. If you go w a dom 1.5 on the 207 post up id love to see results. I think 400 is the max ill go on the stock block and it should handle it fine... anymore it needs to be built further. The v7 block is incredible as is though for anything under that being pre built basically.

Also yeah I still get food mpg when I am driving nicely. The jdm shorter gears made a bigger difference on mpg then the turbo setup did. Still highway around 70 to 75mph im getting 25mpg or maybe even more sometimes.... till I hit the gas.

I feel like I remember reading that Blouch specifically designed the 1.5 for all the ej207 guys across the pond in England. Seems like the obvious choice for your goals.

You're gonna run out of steam at the top end, which is a shame because the 207 likes higher revs anyway.

16g is a good "next step" turbo for the ej205. I wouldn't put one on my ej207.

Honestly I am not sure would have to ask my tuner. Its probably up there but I have 850cc injectors that were flow tested close to 900cc. I know im not maxxed yet thats for sure. You would be ok on a setup my size or a 1.5 you just cant run 25psi... dont need to anyways. Im at 23. Your tuner who is trying to talk you into a 16g on a 207 doesnt sound to aggressive either so the 750s should be fine.

I agree though do NOT do the 16g... its not going to hold up top you wont be taking advantage of the 8200 redline and the awesome flowing heads. Thats a 205 setup. Im not sure why he would advise the 16g. My tuner advised the 18gxt on my 205 to get me around 340whp... it was only safely doing maybe 315 or so on that high mileage motor... you see what it can do now. Anr again if you go bigger then the 18gxt which is a regular 20g size...then go straight to dom 1.5 dont mess around you WILL regret it and you WILL do it over again.

I think a gtx 3071 would be an awesome turbo on the engine, maybe bigger, it might also be a good idea to talk with other tuners as a second opinion

Gtx3076r would be my choice if the wallet was fat, otherwise any holset would probably do.

It is a great turbo for sure and definitely under rated and under used as most ppl go too small like tje 16g or right to a 20g. Id suggest also going w the 8cm hotside and 3inch inlet if your looking for the power I got rhose two things help w top end and peak power... you could go 2.4 inlet and 7cm if you want quicker spool. Let me know how you make out I think you'll love it if you go w it. Make sure the tuner is not afraid to get boost into the low 20s... at 18 or 19 psi your barely using the turbos capabilities. I hit 305whp on wastegate... picked up significant gains everytime we upped boost.

The dom 1.5 is an awesome turbo... it should be about a 300 dollar difference not 100... if its rwally only 100 then I would 100 percent. My 18gxt was 1300 I believe maybe a little less that was w the 3 inch option and 8cm hotside though I believe 3inch was a little more. Tje dom 1.5 I thought was 1600+?

If money is not a concern then get the dom 1.5. W your conservative tuner you will make more power w out stressing the turbo etc. Doesnt sound like he will push the 18gxt to 23psi like my guy did so your gonna want thw 1.5
