Havnt heard anything bad about the gt525s comparable to the sport 500s and 530s from jwt. Obviously with these you'll need bigger injectors a reflashed ecu and upgraded smics assuming you're running stock

[tt300zx]

well i have a front mount intercooler and a z1 tuned ecu i just dont have the injectors. do you need them or just need them to run higher boost because i was running 12 psi on the stock turbos and thats all i plan on running on theses

[ericnjttz]

12 psi on stock is gonna be a lot different than 12 psi on the 525s injectors are pretty much necessary since the stock ones are close to maxed out now. Z1 will reflash your ecu for 50 bucks and there are a used set of nismo 555's for sale used on 3zc for 400 in jersey detchworks (sp) also sells injectors for the z which have been prove to work well and a lot less expensive. If you think you'll go even bigger turbo wise in the future consider getting 740 or 850 injectors

Either way, that puppy's gonna fly! My TT with just bolt-ons and a tune was a lot to handle even.


Hey Eric, how've you been? Still in the Z game?

You'd be more jealous if I told you what I paid haha

naa these turbos are plenty big i only need 555 injectors for sure thanks for the help ill just send my ecu away to get reflashed and pick up injectors at the same time

Your wheels probably cost more

+1 on the bigger injectors comments. If for nothing else, the upgrade should be done for safety. My TT can run 13 psi on my most aggressive (Walbro 255 and stock injectors) however it has a bit of a lean spot. Upgrade the injectors just to insure that you have plenty of fuel to feed those.

Plus, if you decide you want more power, you'll have the ability to turn them up a bit. Better to have to much and have room to play than to have to little.

Not to mention, the motor will be out and it's much easier to do injector work with it out. Do it right the first time and save yourself headache down the road.

Just my .02
