From what I've read about the RB swap, you usually get the RWD GTS-T Skyline tranny to bolt up to the RB.

At stock tuning levels, between the RB25DET, the RB26DETT, and the SR20DET, does anyone know which engine is friendliest with the relatively low octane (91 in CA) we get in the states? I mean, which can retain the most power with minimal drawbacks (ie detonation, crappy gas mileage, excessive pollution, whatever)?

Heh, coincidentally, a friend of mine who has a Supra was just telling me last night how Supra owners on his forum are stuck up.

This' some good discussion guys. I heard there was a conversion rate for like, every X amount of pounds removed from the car = Y secs shaved off the quarter mile time. Is there a similar conversion like, for every X amount of pounds removed from car = Y gas mileage improvement?

Does adding this aftermarket vacuum brake booster thing actually increase stopping power, or does it only restore it to stock levels?

Stock-vs-stock, I know that, all other factors being a constant (ie car body weight, tire combo, etc.) a 4 cyl engine should theoretically consume less gas than an equivalent 6 or 8 cyl of the same aspiration. Now I know souping up a 4 cyl to be as powerful as a larger engine is ultimately going to require more fuel. So my question is, if you soup up a 4 cyl engine, and a 6 cyl engine to the same horsepower level, will the 4 cyl still consume less gas? I realize the lighter weight would contribute to fuel efficiency, but I'm wondering if the engine itself is still consuming less fuel. I would imagine that for normal driving, the 4 cyl of the same horsepower would consume less since it wouldn't be at peak power production all the time. Now let's say we have two engines with the same # of cylinders, but different displacement, both tuned to the same power level. I would ask the same question if the smaller displacement engine would still consume less gas. Any thoughts, confirmations, or discussions would be appreciated.

I've seen aftermarket brake vacuum boosters in the Summit Racing catalog.

I don't get why on earth the RB25DET is the heaviest setup on the list... ^^

Well, when I mean sluggish off the line, I mean like "normal" driving, without dropping the clutch from high rpm. In any case, did you guys reuse the Silva differential/axles, or did you need to convert to something else? Since I've got an NA 280ZX, I've got U-joints, which I hear are not as good as CV joints, so I need a good, simple alternative.

I would suppose you'd have any up-close pics of the mounts would ya? ^^

I was also interested in an SR20 swap in my 280ZX, but I was concerned about being sluggish off the line, since I know the torque won't be the same. Speaking of the mounting, did you weld something new to the frame rails, or did you attach something to the existing mounts on the frame rails to move the engine farther back?

Haha, that'd be freakin' sweet!

Hey, I met you at the JGTC. I could tell you were going for a beastial theme, though I didn't realize it was a shark. I see it now that you've pointed it out though. Hehe, put a big ol' dorsal fin on the roof to complete the shark look! Or one of those BMW roof antennas could work too.

Wow, if you find out, be sure to post it up!

I've got a pair of RX7 seats in my Z also. However, I'll be removing them in a few weeks (got a deal on some Recaros), so I can try and see about scaring up a scale. They don't offhand seem heavier or lighter than any other car seat, but they do hug really well.

So are sub frame supports for repairing of a rusted or weak frame/underbody, or is it a performance thing? I was kind of imagining it as a bunch of crossbars welded to the rail frames like a roll cage or something.

Can someone please explain a little bit more about subframe connectors (particularly for a 280ZX)? Does anyone have pics of what it looks like? I take it, that it's for chassis stiffening, but what kind of work does this entail to install?

Hehe, at a car show I saw a wagon or something that had several of those Bazooka bass tubes arranged vertically and placed in a "box". Each was painted a different color to look like crayons. It was certainly a unique and interesting thing.

Is there some sort of "trick" to putting in the rear hatch piston supports (specifically for a 280X)? It has such great pressure that I can't seem to compress it enough to screw the ends in. Also, the ends of one of my supports have popped out of their ball socket. I can easily put it back on the ball joint, but it pops off both ends when I reopen the trunk. Is that fixable? I don't suppose anyone's ever heard of some alternative to these gas pistons to hold the trunk up, other than a big stick prop?

I didn't find anything in Search, so has anyone heard of, or considered a Subaru WRX EJ20 swap into a chassis? I really love the growl of those boxer engines. However, I'm wondering if their width prevents them from fitting.

What did that 280ZX supposedly have in it? At first I thought it was just parked near an airplane taking off to make it look like it was making that sound.

Has anyone considered a Subaru EJ20 swap? I really like the growl of those boxer engines, but I don't know if their width will fit in a Z's engine bay.

For the JC Whitney and SummitRacing kits, can anyone tell us if their kits come with the "riser" carpet piece, that goes on the speaker/storage area between the passenger and trunk areas? (particularly for a 280ZX)

I didn't come up with anything on Search, so does anyone know someplace that has 280ZX weatherstripping for any cheaper than zcarparts.com/Motorsports Auto? The rainy season's arrived, but I don't wanna get raped on price. MSA wants like $300 for just the driver's side door-body-t top weatherstripping!

I'm installing a device in my '82 NA 280ZX and was wondering where I might find a wire to get the signal for the speedo (Vehicle Speed Sensor) and the tachometer. As I understand it, the gauge cluster reads the speed via a spinning cable of sorts connected to the differential. Do I need to somehow tap into that device to get an electrical speedo signal, or can I get it somewhere else? If not, is there such a thing as an aftermarket add-on vehicle speed sensor?
