I haven't added injector ports to the model yet. As you can see the runners follow the 98 degree incline of the intake ports from flange mounting surface. The plenum is modeled out of 0.125" thickness material. The velocity stacks and runner material are from Ross Machining. The plenum material is readily available. I was going to use the factory intake flange, but the ports are being enlarged a lot from their factory cross section. This just seems like a cleaner way to get everything done. I'm going to model 2 injectors per cylinder. I'm placing the injectors up the runner for better atomization. Justin

I'm not really worried about removing the driveshaft. Maybe I'll be pissed when I need to remove it. For now its all good. I'll figure something out when I do the R230 swap and TH400. Justin

Looks like he is wanting to move on: http://yellowbullet.com/forum/showthread.php?t=67361&highlight=240z Justin

Could you post some pictures of the wheels with tires with a more complete view? I'm trying to decide which color to go with on my Z. Justin

Are you using R230TT or S14 outer CV joints? Is there a different spline count between the two? Justin

Here are some pictures showing the transmission and driveshaft clearance. I don't think its going to be an issue on my car. The exhaust is going to need to get updated until I drop in the 2JZ w/ side exit exhaust. BTW, please excuse the big hole in my floor pan. I removed the catalytic converter bulge to make more room for these wide s2k seats. I'll be welding in some new sheetmetal

Say I connected the two tubes like you say. I imagine I should plate that entire area then? Justin

I'm going to be running S2000 seats. The tubes are spaced 12" apart. I'm going to plate the rocker and the 45 degree edge of the floorpan. Then I'm going to weld the seat tubes to that. I'll get more pictures up once I'm further along. Justin

Here's what I have started so far. I'm going to have to do some more cutting to lower the tubing down a ten of an inch. I should be able to weld in the rocker plates this weekend and get this thing all buttoned up. Justin

I'm doing coilovers on my 280z. I'm just unsure what struts to use. I wanted to try the Bilsteins (F4-P30-0032-MO). They seem like a big PITA to do on a 280z strut tube. I'm left wondering if I should do Tokico Illumina's or HTS112? Do the HTS have enough travel for drag racing? Are there any other recommendations that aren't over $175/strut? Justin

So I'm making seat mounting brackets in a bit of a different way. I've taken 1" X 2" X 0.083" wall tubing in 5 ft lengths. I've cut away the existing seat brackets. I've also cut holes in the floor pan so that I run the rectangular tubing from the left rocker to the right rocker. The way I have it currently it slips in just barely over the factory floor pan. It sits on the underside of the rocker/dogleg. I'm wondering if I have to plate the rocker before I weld the 1" X 2" tubing to it? This would cause me to space the tubing down another 0.125" lower. I am already touching the bulge on the passenger side floor board that is there for the fuel/brake lines. If I need to plate the rockers before welding the tubing to it, I'm going to need to cut away the factory floor pan in the area of the bulge. I'll get some pictures up tonight when I get home. Btw, this does limit exhaust clearance. I'm doing a side dump exhaust that will exit out the passenger side fender and run along the passenger side rocker. Thats the only reason I'm able to get away with this. Justin

I don't believe you need the injector driver box for the secondary 160lb/hr injectors. Since they won't be used at really low pulse widths you should be able to control them fine. You just need to make sure you keep the current usage down to a reasonable level per injector output. I'd imagine you are going to pair the secondaries to injector outputs 7,8 & 9? Regards, Justin

Hey Guys, I don't have enough room for a lift in my garage. I've been thinking of picking up 4 of the 12 ton jack stands from harbor frieght. The main reason I want them is the 30" max height. That would be nice for working under the Z Just curious if anyone has some good input for me? The only problem I see is geting the Z up on these jack stands. Min heigh is 19.5". http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=34924 To get the Z off the floor and up on the highest setting I'd need this jack http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=42820 Justin

Yeah, shouldn't you be able to get the pulse width low enough with the 72lb injectors operated sequentially? Justin

Doug, Here's you UPS tracking number. 1Z99E7F36880555000 -Justin

Thats a good price. I'm machining my own since I have the RMR tool for my 2JZ build. I hope you can get 10+ people that need this rail. Justin

The harbor freight grinder is pretty big. Its nice since you have the aluminum shaft to hold onto close to the collet. I couldn't use it without the speed control though. It runs way to fast out of the box. Its over a foot long. I'll measure it when I get home. Edit.... The link says its 14.25" long. BTW, I got it for $30 in the store when they had a special. Justin

If someone wants to compare the dimensions I posted above to the palnet fuel rail that may be a good option. I'm unsure if their spacing is the same. Justin

Btw, those that are looking for a affordable tool to port match their cylinder head. This is what I'm using: http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=44141 and this router controller to turn down the RPM: http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=43060 Its been working great for me so far doing all kinda of cutting on my 280z. Regards, Justin

From what I can tell from the original models Ron sent me, we'll need about 3ft of runner tubing. The best price I've found on the 1.75" OD X 0.125" wall was $9/ft: http://rossmachineracing.com/175tube.html Anyone find a more affordable source? Justin

Bump this back up. Should I do 18ga or 16ga? Justin

I was trying to have it shipped here at work with the last two packages. They gave the package back to me yesterday because they can't ship personal items international. I'm headed to UPS in an hour. Sorry for the delay. Justin

Can a R230 differential be easily added to a 240sx rear suspension? If not, will it only bolt into to? Are the 240sx, Z32 and Q45 IRS the same? I have a R230TT diff and axels that I was intending on doing the conversion with. I'm thinking at this point I want to get a Z32TT "stub axels/ hub" for my car. I could do this by either doing the TechnoToy Tuning R230 kit or swaping in a Z32 IRS. Regards, Justin
