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.

      Not too sure just yet, want to have a go at doing what I can myself, but to start with want someone to cast their eye over it tell me what needs doing to get it running and back on the road, so anyone with great overall knowledge would be ideal.

      Rear subframe stay bracket bolt removal issues

      By MBS206 · Posted

      I personally would go with cutting out the rubber. Then deal with getting sleeve off separately. Rubber can be painful to cut, it loves to jam up cutting tools. I normally have success with drill bits, deburr bits, angle grinders, jigsaw, reciprocating saw, and never forget... fire. Obviously different tools won't work in all locations you're trying to work with, and you need to be comfortable with each. You personally may be happy slowly slicing it out with a razor blade, if you are, go for it with one too! Feel free to wait for others to weigh in also on their thoughts.

      Rear subframe stay bracket bolt removal issues

      By DatsunBanana · Posted

      So ... I got everything disconnected and started dropping the frame. Three of the four mounts started to come down but the fourth one (the one with the nut that gave me all the trouble) won't budge. The inner metal sleeve stays up tight against the chassis rail although the outer part of the mount drops a bit (and can be levered quite a lot more) but it's just stretching the rubber bushing. So I reckon there's some serious corrosion inside the inner sleeve and holding it tight to the lug at the top of the bolt. Tried everything I can think of so far: penetrating oil, whacking the top of the sleeve to vibrate it and wedge a screwdriver blade in there. I also tried to turn the inner sleeve a bit by hitting it with a chisel at the bottom. It's stuck solid. What do you think about cutting the rubber with a blade so I can drop the subframe around it anyway. Then worry about getting the inner sleeve off after? Will that work? Is it gonna give me even more problems?

      Blue/grey smoke after idle

      By hypergear · Posted

      Steam valve seals are usually responsible for cold start smoke, it goes away once engine warmed up. Disconnect it let engine breathers and let it breath freely, see if problem goes away after a short drive. Also check to make sure engine oil drain pipe is not blocked or kinked.

      Haha thanks! Yea I'm moving over from 2x 1000cc jets pre throttle over to 6x 190cc direct port jets and 1x 500cc pre throttle jet.  Direct port comes with all the advantages you would expect, except that pre throttle does cool down IAT'S more. That's why my direct port nozzle placement is closest to the plenum as possible in the runners to allow the air more time to cool before being sucked in. I'm also putting that one 500cc pre throttle jet to help with more cooling. It's a hybrid system. There's a lot more advantages to moving over to a PWM solenoid with a constant pressure system vs my old PWM pump setup, but I'll get more into that once I'm done converting everything over. The ricer in me is excited to see SS tubing all over my manifold though!
