If those are the typical watanabes, then 16X9 -13 upfront and 16x9.5 -19 rear. There are other sizes, but that is the sort of idea. They look to be a bit smaller.

Richmond, Oakland, and Fairfield usually have S130s. Fairfield is the least ghetto. Talking P-n-P. Otherwise pick your part in Hayward which is also really close to the shelf style auto recyclers who should have what your looking for as well.

John, with ZG or equivalent flares though, what offset would be adviseable for this 17 by 9.5" wide wheel? Thanks.

5" BS on a 9.5 inch wheel would be... 9.5+ 1" Lip = 10.5/2 = 5.25 Need -.25" = -6 offset But is that too close for the front. Not talking strut to tire clearance. I mean tire to frame rail. My +10 16X8 grids touch with a 245 tire to the frame. Not badly, but enough to make it not clear. That would be the same back space. Could always use a bit of spacer, but it would be nice to make these fit right. Maybe rear and front offsets should be different while maintaining the same width? Watanabe 16X9 fronts use a 4.5" backspace same goes for the Wat rear. Maybe we should aim for that to be conservative? Something like -15 in the rear and -8 to -10 in the front using a spacer if needed.

Okay. I agree on the offset comments above. I doubt these will fit without flares though so attention to all those planning on running stock. The wheels are probably just too large. I have emailed Kim asking her to confirm that all we need is 25 sets of the same width and diameter. I also asked if I should compiled a list of people who are interested and their emails. Lastly I asked her to confirm a time estimate based off the knowledge that rota sometimes takes a while to deliver. She is the head of all north america for rota if I understand correctly and she has an office/warehouse 30 minutes from me. I might go meet her in person. I figure we are going to need a list of people who are commiting anyways so please if you would like to get on this, just type your email and name and I will compile a master list edited into the very first post of this thread. DO NOT TYPE if you are un willing to commit. The price is $750 a set shipped to anywhere in the continental USA or $700 picked up in Hayward, CA. Also, I did contact the 240sx forums and put a group buy post up, we shall see...

Wow, thank you very much! I have work in a few minutes, so I haven't had a chance to read your article, but i did notice on the megaefi website that they listed the unit as being able to run fans. Does this include the two speed Taurus fan?

Hmm. Thanks for the heads up. I think they also did a pickup liftgate in a water tunnel. In any case I am talking to my brothers ex girlfriend via email. She has built a 1200mph windtunnel which refracts a laser on a turbine for some reason. Not sure about it all yet as we are just starting to talk. She said she will take me to see her tunnels though, so that is cool.

It is $750 free shipping in the USA for 4 in 17X9.5 -20 offset. What do you all think? We would need 25 people... thats alot. EDIT: It doesn't have to be that size either, I just figure that is going to work out back. Does anyone know if that would be okay on the fronts with ZG's or is that really pushing it. I know the Wats are -13 16X9's, so these would stick out an extra half inch or so I would think. These would be really serious wheels though. Ever see the lip on a 16x9.5 -19 watanabe... its fat. These would be a similar lip depth.

If I end up getting these wheels I will definately run flares on my car. If I stick with the 16X8 Rotas I have now, maybe, maybe not. I used to think the same about 17"s on S30's. I think it looks fine now after seeing the cars with CCWs and other peoples builds. My main issue with 15" and 16" sizes is that there isn't really anything larger than 245 maybe 255, unless you go into Hoosiers and race tires. 17" you can go up to 285mm no problem with a wide selection.

Ya I agree. Nothing ever got done by not trying though. So here it goes: Rota Group Buy for 17X9.5" RB's http://forums.hybridz.org/showthread.php?p=785018#post785018

I guess, I was talking about their lightest wheel though which is made out of thin steel. Hence why they request you contact them before putting it on a 2500+lb vehicle.

I have been in contact with the Rota representative who is located about 30 minutes from my home. I inquired about having the Rota RB (it looks like a rewind/watanabe) made in a 17" by around 9-10 specification to our desired offset. A total of 25 people (100 wheels) would be required to run this deal. I think this one might be a long shot, but they are very attractive wheels and a 17X9.5 or so in a low negative offset might be just the ticket for our Z cars. EDIT: Update - Pricing is $750 for a set of four shipped any where in the continental US. If you pickup in Hayward, it is only $700. These wheels will be setup to clear a stock suspension, but will most likely (almost 100%) require flares or fender rolling. I am working on determining the size that fits at the moment and will be making cardboard wheels in a 245/40, 255/40, and 275/40 size. The rears should fit 275/40 no problem. The fronts may need to step down to 255. We shall see. This will help me to determine an offset that works. If you are interested and willing to jump on this, please express it. Suggestions on sizing are welcome as well. Images are in the link above. LIST OF GROUP BUYERS (Needs 25): 1. Rudypoochris - Chris Moris - chrismoris@gmail.com 2.

Yep. 25 sets or more she said. I have no clue how many people are interested. I think I shall start a group buy.

Thats great to hear that it only really omits the automatics and emissions. Since I am using a manual and am emissions exempt (although I do hope to try and save the air as much as possible). As far as configuration and installation goes, is it the same process as using a standard megasquirt (as if the adapter wasn't noticeable) or are there other hassels that come along with it?

www.megaefi.com Apparently there is an adapter to connect a Megasquirt ECU up to the stock 87-95 Mustang EFI harness. Has anyone had experience with these or a similar product? If so, do they omit any functions, are there any draw backs to them versus using your own harness? Thanks!

Right now I am just asking her about 17x9 to 17x10. Mainly because that is what I am looking for. Something in a 15X10 or 16X10 seems to be quite limited for tire selection. Hence why I am asking for 17. Her email is kim@rotawheel.com though, never hurts to ask.

Is that differential an open 2 pinion unit? It looks like it. You might have more success with an LSD or a 4-pinion (or combo) R200. Or am I missing something here?

I love the looks of Diamond Racing wheels, I just don't like the weight. Their 16X8 in the lightest series (they ask you to constact them if your car is over 2500lbs on these wheels) is 21lbs.

http://rotawheel.com/rb1.htm Should already be out... also the 17X8.5 is out. I'm currently in contact with Kim Bong @ Cosmic to see how many people they need to run widths in excess of 8.5 in. Her last reply, yesterday: My response:

I did notice that low speed drag seems to follow a more linear function, but I didn't think gears spinning fluid was low speed. I was also perplexed by the fact that the engine dyno seemed to have proportionally lower resistance until about 4500rpm when the values started becoming the same constant (check hp loss). This might indicate that a certain point all the fluids are flying any way so they don't impart more drag if the speed increases. Just food for thought any way....

I am in the middle of researching drivetrain loss for my website, and thought I knew what was up... guess not. I didn't think it would be a constant percent... After compairing dyno results from a stock LS2 on an engine dyno vs on a chassis dyno it looks compellingly so. Below are the results. The engine dyno is of unknown make, the chassis dyno was of the fixed inertia type, I believe, but am not positive. Can anyone make sense of this one? I thought since drag is usually proportional to velocity squared that so would power loss... This clearly shows a static percent... hmmm... If anyone has engine dyno graphs of common engines could you send them this way? Could the reason for this be explained based off of the way a fixed inertia dyno works in comparison to an engine dyno?

Yep. I was driving my parents GS350 today and I was thinking man this feels awesome. I was wondering how it really stacks up bottom line. There is 3700lbs swinging around even though it kicks out over 300hp. I was very disappointed with the automatic transmission lag though, seems like auto is really the only option on the larger sedans now adays unless it is a BMW. The mileage is pretty bad imho. I think these modern ultra sensitive gas pedals have me yanking the car a bit just in normal driving. Maybe I am not used to it, but I notice other people doing it too in their own automatic sedans.
