From what I can tell, Modified_85 on this page http://www.redz31.com/turbofaq/intercoolers.html has a Treadstone TRV185. Flow wise, that TRV185 should be more than enough as it will support upwards of 720 hp. That up/down style is supposed to be the most efficient, and it makes sense, so that would definitely be the way to go if at all possible.

I know for sure the 90-93 Q45 R200V has 30 splines, just counted.

I think I may look into that. I read up on it a bit and now that I understand better exactly what it does that will definitely make it a little easier. Thanks!

I'm working on a project right now that I have to deal with this and had a question... What if you don't have any access to the backside of the spot you're patching? Can you still spot weld the patch on and grind it smooth or is there another, better way of doing it? Its an exterior piece that will be painted once finished, I just have no idea what the best route of doing it would be. Thanks in advance!

I wouldn't even mess with a clip. You could get a long block from a Maxima and just swap everything from your Z VG to the Maxima VG and it would drop right in.

You'd have to get a 350Z 6-speed for the transmission I believe. I'm pretty sure that one bolts right up to the VQ however I know for sure that the VG transmission will not. Also nothing on the VG will swap over to the VQ that I know of, they're totally different. Doing the mounts and such should be a pretty simple task however I think the biggest issue will just be wiring everything. The VQ runs on an OBDII system, which could cause some headaches. The cheapest and easiest way to get it going again would be to get another VG30E. They can be found in salvage yards for very cheap. The VQ would definitely be more fun than the VG but you will definitely have to put some work into getting it in there.

From what I hear, its lighter than the SR20DE but I have no solid info to back that up. All I know is there was someone who swapped a VQ35 into a 240SX after having an SR20 and the front end of the car was slightly higher with the VQ, no spring changes.

I personally believe the VQ has even more potential than the VG once its been built up. Stock for stock I know the VG will hold out a little longer but, regardless of having an aluminum block, the VQ can definitely make some insane numbers as has been proven. I'm not sure why most people can't believe that.

A VG30ET would be a pretty good choice as well I think. Its at least 100 lbs. lighter than the VG30DE(TT) and is quite a bit more compact. It is also very strong like the DE(TT) and can make a ton of torque and power.

The VG30DETT uses T22/T25 hybrids.

If its a case of over heating you'll definitely want to check for warping in the heads. That's usually the most common cause of bad head gaskets when over heating occurs.

Same thing, just swap the pickup tube and oil pan.

It'll swap over perfectly. Just take all of the external stuff from your engine and put it on his then drop it in. Same castings for the heads and block so the motor mounts, accessory brackets, everything will swap right over.

Ahh, nice deal. I can't believe anyone would really buy anything directly from them..... they're so overpriced that I could get a custom set of pistons made for my VH45 probably 2 or 3 times for the price of theirs. With those pistons that thing will definitely have some very nice low end compared to a low compression setup and should get pretty decent gas mileage. I'm going to be running the stock 9:1 compression in my Maxima with a Holset HX35. I was using the 8.3:1 engine but the low end was just terrible compared to the 9:1. Going from 8.5:1 or even 9:1 to a 10:1 setup would make for an awesome power band. Definitely, definitely get some videos of it when you're done. I want to see what that thing will do.

Yeah, I'm going to toss it in the oven and see how it does with an even heat. If it doesn't work from there, I'm just going to make one like the Thaggard one.

Wouldn't need... the valve? It wouldn't matter what setup you have, it'll allow the turbo to spool quicker regardless. Not sure on the intercooler, you'll have to search around a little bit. I wouldn't try fitting the largest intercooler you can in there, just the size you need for the power you're aiming for. On to the valve. Finished it last Sunday and finally got the pictures... I still need some more welding practice but the new welder definitely makes a difference over the cheapo welders. Now I just need to get the Maxima running so I can test it and check for leaks in the valve itself. http://www.machzracing.com/Maxima/QSV/P1020193.JPG http://www.machzracing.com/Maxima/QSV/P1020192.JPG http://www.machzracing.com/Maxima/QSV/P1020195.JPG http://www.machzracing.com/Maxima/QSV/P1020194.JPG Threaded the holes to make for an easier time bolting it all up. Due to it being square, a nut or bolt wouldn't have fit and this looks better anyways. http://www.machzracing.com/Maxima/QSV/P1020201.JPG The clearances are a little too tight for the valve to open and close smoothly so I need to modify the inside of it a little bit, but once I get it working smooth it should work very well. More to come!

Holy hell... they make expensive stuff. I didn't think they made any high compression VG pistons though... it should be somewhere around stock TT compression ratio I believe, unless its a custom piston.

And people wonder why I won't own american made vehicles... Granted I wouldn't mind a new Corvette or a Ford GT... TT... but I would never turn away from Nissans.

Are you planning on building up the engine aiming for that power? I could see the n/a setup maybe handling 400 whp or so, maybe, but at the power you're aiming at you'll definitely need to get some better internals. I'm sure you already know this but I just wanted to be on the safe side. The 60-1 doesn't have the greatest of maps imo but it should definitely flow enough for the power lever you're looking for.

Really you won't see much of a lag difference between twins and a single if both setups are sized properly. There's actually a stock single turbo VG setup, the VG30DET over in Japan. It uses a crossover pipe over the bell housing just like the VG30ET in the Z31 300ZX. Intake manifold is different than the VG's over here but it still has dual throttle bodies, just pointing to one side of the engine.

That's what I'm aiming for... hopefully before the end of the month. I'm going to work my ass off tomorrow on it so hopefully I'll get quite a bit accomplished. If I have enough pipe I should be able to get the turbo set in place and get the crossover pipe welded up. Finish the aftercooler piping and the rest of the exhaust. After that I just need to wait for the headgasket kit to come in so that I can put my 9:1 block with the JDM heads... hooray for a whopping 10 hp or so with euro cams.

pull the engine, tranny, diff, and cut a hole in the floorboard and do a fred flintstone! That would be good for at least 500-600 lbs. (i'm sorry, i don't have anything better to add)

That's what I thought it looked like but I wasn't sure. The idea had crossed my mind but I wasn't sure if I could match the radius... and... was just too lazy to check.

Ehh... I already have exhaust shooting into the engine bay from bad exhaust studs. I'll be fixing those once I get the engine out though.

Actually I did see your post and was going to ask you how you did that but kept forgetting... so... how did you do that? Its just in a tight fitting bushing basically. I was worried about leaks but I set it up like the internal wastegates so hopefully it'll work the same. Pressure will be a little higher on this side of the turbo compared to the other side like the internal gates but I'll find out the hard way. I'm also curious how James sealed his valve, it doesn't look much different but I'm not sure.
