My fronts are 17x8, 25mm offset. The arms are 10mm longer, They didn't make the wheels in the offset I wanted so I had to add it at the arms. With 10mm less wheel offset my track would have been the same though. Justin, I can get the tire to frame rail to tire measurement next weekend If there is another measurement you want off it I can get that too. I think the wheels on that SC are 7's.

Tires, wheels or offsets? The S30 is the one in my pic. The wheels are about 1/2" short of being flush with the fenders.

Most people on here don't run big turbos or boost. A few do though. Boost isn't the limiting factor, it's detonation. Cast pistons are not very forgiving at high boost. You can run 30 psi if you want on turbo pistons, just don't let it knock. Timing and octane are critical at high boost. By support do you mean spool? Someone on here is running a GT42 on an L28. Wouldn't spool too quick in the lower revs but the engine will spool it. Turbonetics uses Garrett based stuff. I used one of there T58's and now have there T72. Works fine. Have a Precision on another engine.

I was at Andy's (2fiddyZ) yesterday and he has a gutted SC300. He said they use the same crossmember/suspension as the SC400 ad MK4 Supras. He also makes big brake kits (Wilwood) for them.

Don't know what it reallly is but the compressor wheel is pretty small and smaller than a T3 60 trim. There's a bunch of specs here. http://www.hksusa.com/categories/more.asp?id=1092

Ball bearing. They are pricey. I don't know if you are registered or need to be to get on to SF. If you aren't there is alot of info on there. There's a bunch of gt2835 links here with dyno sheets too. http://supraforums.com/forum/search.php?searchid=2178344

There's no way a vented rotor is going to work with a solid rotor caliper. This is just slotted. I don't think you'll notice any difference. You would be better off with a race orientated pad or going with the Z31 stuff Jon mentioned.

Stock cam, exhaust 2.5" L28 12 psi V trim /stock T3 hotside. Don't have the torque curve Stock cam 3" L28 15-16 psi V trim / O trim .69 horrible fuel. Stock cam 3" L28 22 psi V trim / O trim .69 Not an L28 but similar in size and turbo 3l 7M 21psi T58 / O trim .70

Ya, alot of people want that low rpm boost with a big turbo where on a high hp n/a car you wouldn't expect low rpm power. I'll look for the dyno sheets. Yes the center sections are the same for T3-T4 unless it's a big shaft, which the T series stuff is (T66 ect). If you swapped to a T4 turbine on a T3 center you would need the T4 heat shield too.

Don't know about RB's but 2jz guys run twin 2835's. kinda expensive but are good for around 800 rwhp.

ya, Someone on here, I think it was Pyro? in the high 200's but your right. I haven't heard of anyone over 300.

You have to post a vid when you get it running.

Ya think 4200? I can get 20 psi with a T72 P trim .70 on a 3L. I know that .58 is making 18 psi way before 4200 on the L28, even in second. If you want bolt on then a T3 flanged turbo would be easiest. That .63 on the turbo coupe is the same hot and cold side as the S130, just a different turbine outlet bolt pattern. Z31 T3 is the same too. I wouldn't go buying parts turbos unless you are comfortable rebuilding them yourself to save money. You may end up with an expensive stock T3. What are your power goals and how much boost are you wanting to run? That would help you decide. With a turbo that will make more power expect some more lag. I also wouldn't run the stock hotside with a T4 compressor. Half the problem is the turbine side. My second Z turbo was a V trim/ stock T3 hotside. When I went to the V trim/ O trim .69 it made about 80 more hp. Look at the Holsets other guys have been running. They are fairly cheap.

Holy mother of torque How much boost? What turbos? What rear and tires?

Ya, they are at the edge but still atleast 65% at peak HP, not through most of the power band. Not the best but still in on the map. 60-1's and GT35r's have made 500rwhp many times and only flow around 60lbs. Garrett rates there GT35r up to 600hp with about 5lbs/min less airflow. For less than 20 psi I wouldn't change them.

Ya, I was running it. I needed a little more. I went with a Precision (PT61) GT35R compressor with a P trim and .58. The compressor wheel isn't much larger (heavier). I have auto crossed it twice with this turbo but have no idea were it comes as there isn't time to look at the gauges. It makes boost fast in the rev range I use the car at though. I will get some in car cam of the tach, boost, ect in a few days so I can see exactly when it comes on. If you are comparing a P trim/.58 to a stock T3 it will have a bit more lag. If you are comparing it to a full with a P trim/.68 it spools fast.

Fast. At least as fast as the O trim/.69 hotside I ran with a V trim. I'll let you know exact RPMs after Sunday.

I still don't think anyone has looked at a 60 trim map X 2 and at the pressure ratio he is running.

Sucks they sent it to you in mph. They should have one with rpm and a torque curve? They got a good tach signal.

It's the torque that is the limit on the clutch. You will either need a stiff PP and a marceled stock type disk for stock like engagement or a 6 puck and a stock disk for a soft pedal but harsh, quick engagement. I would run the PP that 1 Fast Z is running. Act is good but pricey. I would stay away from Clutch Specialties. I had good luck with them along time ago but last year I had to get the credit card company to refund me. Ended up using a Clutchnet puck disk.

The stock T3's run out around 12 psi on an L but not from the boost but from flow. He's running two. They are good for an easy 27 psi at 70%. Looking at the map he shouldn't have a problem getting an 600 rwhp and maybe some more out of them, especially with how easy his motor makes power. I've seen alot of dynos were the cars make more than the turbo should have. A 750 flywheel hp Electromotive car would only be making a little over 600 rwhp. Another 10 psi should have him easily above that. Bryan, we could have stayed on there longer if your radiator cap wasn't burping and your WG controller was working right

Can cause silicosis doesn't mean it will, just as years of smoking can cause cancer. I would definitely wear a dust mask though.

So sorry:roll:. I guess I don't see all the posts on here and didn't want to search to see if it was posted already.

Found this on another board. http://www.twinturbo.net/net/viewmsg.aspx?forum=general&msg_id=2079707

That's pretty funny:lol:
