There is a great "group buy" for springs, shocks etc all set up for an R33. If you have the cash this would be the way to go.

The shocks/spring are dead easy to remove, jack the car up to remove most of the load on the springs; undo the nuts at the top and the bolt at the bottom, jack it up a bit further and it will fall out.

Repeat in reverse to reassemble.

There are plenty of good front mouns for sale (new and second hand) as a minimum get a GTR unit, or the Hybrid units are quite good. Make sure it includes all pipes and silicon joiners (between $500 and $1000)

Boos t needs to be kept a lot lower than 20psi unless you change the turbo. I wouldnt worry to much about 12psi, but 14psi for any length of time can be a great way to get a new turbo. To help you here make sure you get a good bleed valve and ensure boost dosnt creep too high under load, or better still get an electronic boost controller.

If you want to run 20psi with any turbo you will need to upgrade your fuel asystem as well (pump and injectors)

PS you will need a new ECU to make the most out of your mods. Most people recommend a Power FC, but there are others.

Hope this helps.

hey i ran 1bar (14.5psi) of boost through a standard RB25 turbo on my RB20 for about a year and a half day in day out, and the car got thrashed and drifted pretty much evryday and the turbo only recently gave up at last drift practice, but didnt go bang, just the seal got farked. But you can run up to 13psi pretty safely on those turbos, any more than that and u do it at ur own risk. might last u over a year like mine or might go bang the next day :)

      Duncan's V37.......race car?

      By The Bogan · Posted

      Can you log IAT? Whilst WTA coolers have their place, doing any sort of sustained run is not one of them There are fixes that slow down the heat soak, like ice boxes, which don't last that long, and interchillers, which are fairly expensive, up grades to the WTA cooling radiator, which may require a bigger pump, and upgrades to the reservoir size,  and upgrades to the cooling fans, but, it all still heat soaks, and takes ages to come down in hot weather  For a turbo, that isn't locked into WTA like my PD blower is, can you not possibly swap to a nice air to air intercooler????, it would be better for sustained runs then, and have alot less things that could go wrong in my opinion

      So, the other thing I've sorted is a baseline dyno run up at Unigroup's new location. The auto trans was a little unco-operative by both shifting down when the throttle was floored on the dyno (so Mark had to ramp it up more slowly than in a manual) and also by shifting up at 6,000 even in sports mode instead of the indicated redline of 7,000 Still, on a hot day it made 240rwkw at 16psi which seems about right for 300kw (400hp) through an auto at the wheels.  The shape of the curve is not quite right because it was not full throttle to about 4,500 to stop it kicking down, but until I can get a tune on the auto trans control this was the best we could do.....full boost will be well below 5,000 once that is sorted, I'll get some data logs when I can to confirm For comparison, the R32 made 255 at 12psi (at 4,500) on the same dyno with tune, n1 turbos, cam gears, big exhaust but otherwise all standard so the v37 is likely a little better out of the box. One thing that is very clear is that the standard water to air intercoolers are not up to sustained use at full throttle in warm ambient temps. After about 5 runs (so only a few minutes full throttle), it was pulling boost and timing and dropping 10-15% power. Unfortunately I didn't get that printout and the Unigroup guys are away at the moment, will try and get hold of it on their return. So, looks like a healthy engine to start modifying and the only real area of concern is the w2a heat exchangers which the aftermarket has plenty of solutions for

      MLR's Bogan cruise ship

      I maintain it actually looked really nice in person. So much so that I thought "No, this is illegal" but there it was, clear as day. I think we can easily call the wing and wheels/height to be transformative. Not saying it's better than the GR Whatever, or the 86, or the WRX STI or anything of that sort (the internet says it all bolts up so you can buy best of all worlds?) but it's still at least a thing and not nearly AS bad as people say.

      That's less offensive than the previous gen.....except for all that ugly black tupperware around the edges. Blerck!

      I leant out the window recently and took a picture of this new WRX. It looked real damn fine in person. It's faster around a track (stock) than a (stock) GR Yaris. It's much more practical despite being heavier. It's significantly cheaper. This gen tunes really well, much better than others. .... I think they're probably a lot better than people expect.
