Hi I've got an r33 gtst s2. I have done a fue mods to my care from suspension breaks through to the engine which is where I need help. I have upgraded the coil packs, inter cooler, pod, turbo timer electronic boost controller and a new upgrade turbo to the car. I'm wondering if I should now do the computer and if so what to go for. My budget is limited as I've blown the bank ont the rest of the mods any ideas. I've tried doing a tone of research but keep coming up with all different things

This has been covered a bazillion times and I should tell you to search and/or read the stickies. Nevertheless....

Easiest is to buy a PowerFC. Next easiest is to get a Z32 ECU modded with Nistune to suit R33. After that there are various aftermarket ECUs that come in plug in form.

If you really want to bump the power you're going to run out of injector and AFM capacity, so you'd need to upgrade those. AFM only needed with PowerFC and Nistune, otherwise you convert to MAP sensing.

You need ay least $1500 to start this exercise. Got to buy the ECU, get it fitted and tuned. Injectors and AFM upgrades will cost more than another grand, and you will want to upgrade the fuel pump probably even before you have to do those (old std fuel pumps are just waiting to diw and kill your engine, especially when you wind up the boost).

For budget, contact Toshiba on this forum. He will be able to do a mail order remap for your mods at cheap price.

Username = toshi (unless he's changed it). You'd still want to do a dyno run after just to make sure it doesnt ping. Toshi has to make his remaps on the assumption that all the components in your car are working normally, if they're not you may find that while it wasn't a problem with the super conservative factory tune, it is a problem with the remap. Also, the remap tune can never be as good as a proper dyno tune, however, it will be way better than the factory tune.

    • I've replaced the front brakes of my NA to 324 brembos and 350z calipers: i'm going for 225/40-18 up front and 245/35-18 in the back. I have Rays 7.5*19 ET35(225/35) in the front with 5mm spacers otherwise the calipers "lock up/ won't rotate". When i use the calculator i come up with 8*18 ET30 for 225/40...... but not sure i get problems with the calipers. Anyone riding around with 18 inch. that can confirm "that it'll fit"? In the back it's 7.5*9 ET30 (245/30) with the 5mm spacers, but there is no problem with the standard small brakes, so i want to take 8.5*18 ET25 (245/35).
    • Lol.. but then.. always come back to a JDM..
    • Glad to hear. If possible, get your tuner to check air's to make sure everything is still where it should be.
    • The problem with FB/Insta/Reddit etc comments relating to cars is simple. You get to ask a question once, and get one round of replies. For things that can actually be answered in a few lines of text, once, it's fine. After 6 hours, your original question is lost to the void. There are no follow ups, additional questions, anything. No project car is ever such a simple list of questions to ask. You need discussion.
    • Welcome.  Here's what I have noticed about forum vs FB..... FB; seems to be wallet racing, and the same few questions asked over and over. There *may* be some groups that are closer knit, but most have changed for the worse. SAU; unfortunately, no longer in its glory days. But....genuine people with similar interests. Not all about how much you spent and saying you dont have enough power. Sooooooo much knowledge available. Have personally seen people post up about literally topics I made myself, asking on FB like no one has done it before. Most has been done, and most of that is here.   If you ever feel like just general chatting theres the wasteland.  Other interests are also generally covered in other areas of the forum. Hope you enjoy hanging around. We would love to have you.   P.s. nice 32 😀
