I may need to see if someone had a fender roller i can rent, fucked up and didnt do it before the paint..

This is only my opinion, but a fender roller is a waste of time and energy. I used one on a friends s14, the real nice expensive one, and its super time consuming!! I found a MUCH better approach is to purchase a good selection of wood dowels from a lumber yard in the area. Start with a small dowel, like 1-2" o.d. , and continue on up in size. Its much easier, as the weight of the car will do all the hard work, and have a friend push it forward and backward. You will have to get a hand for it, like how much of a angle on the dowel while rolling, but the results will be very nice once you get the hang of it. The front of the FD is hard though, as the fenders are aluminum, and the paint will crack easy if its not soft enough. Good luck!

Oh-BTW- Nice progress!! The car looks great!

Are you going NA rotary with this project?

Yeah, its going to go 13b PP with fuel injection

Damn, very very impressive Rob. This car is going to be absolutely killer when it's done.

Nice! Good luck!

You rock, I want your car

This is very nice... too rich for me though... If only I had the money...

Lookin good. Just curious, what size tires/wheels you looking at? I am building a FD for local track events.

I can't wait till I'm out of college and can do stuff like this. Oh well, at least I can auto x

LOL ! you just gotta work hard to play hard. as for the tires, i will be using 285/30/18 and 245/35/18

why not 285's all around? they fit with coilovers.

Tire sizes
 

I dont think i should go any bigger than 245 in the front because of the turning issue. may hit inside the well. has does anyone have any expirience with this?

Run 285's....... as long as your offset is correct.......I believe 45-50mm.....( I may be wrong) you shouldn't have a problem........

To take it one step farther hoosier makes a 295 only .4" wider then the 285.
The 18" wheel makes fitmint easier.

I am running 17's..... 275 front and 295 rear...It is a great set up but I can't get the front end low because of the overall diameter.......an issue you won't have as the 285/18 are about the same diameter as stock.....

BTW...I ran 245/40 17 up front for a while.....and the car was very very low....great aero but lousy geometry.....changing to the 275 front and the increase in ride height has dramatically improved the "feel" of the car.

Go 285 up front, you won't be disappointed.

A smaller front tire is desirable on the street, but you'll want the bigger one up front on the track.

Nice progress and can't wait to see it in the light.

Either roll or cut the front lips from the fenders for 285/30/18's up front. If you don't under compression the tire can catch a lip and rip it out.

+50mm on my 18x10.5" CCW's works great. Call John at CCW to get hooked up. Titanium bolt options saves 10 ounces I believe per rim. Mine were 19.6lbs.

Good reference here: http://www.negative-camber.org/crispyrx7/

I love the color and the black roof. Can't wait to see the car in one piece.

i gues that i will have to go with an 18x9.5 rim all the way around and then go with 285 all the way around. just have to make sure i can find a 45 or 50mm offset

IF you don't have rims yet, go at least with a 10" width min.

Even if you don't end up buy a CCW wheel, John can give you the advice you need to get the correct size....

Although I don't have CCW's now, I highly recommend them as I have had them on previous cars.

since your putting all this money into this car why stop at a N/A 13B PP why not a N/A 20B pp? sorry if this was already asked i just glanced through all of the posts. i'm not really sure what the max power you can get out of a N/A 13b but it doesn't seem it could be enough to full utilize what kind of car your biulding here. it would seem way underpowered. maybe this is in the regs for scca same engine N/A. i guessing your building this to compet with older FCs and Miatas?

Engine
 

2 reasons i cannot do a 20b PP. #1 $. Dont have the cash. This may look like an expensive project. And thats looking at it from a perspective that im doing everything myself other than the roll cage and the paint. Im already running into fund shortage situations and im not even complete with the motor yet. second. The car is being built to compete in SCCA GT2 class which is allowed to run 13pp as of last year. for me to run a 20b pp. i would have to run in GT 1 and in that class the least of my problems would be older Rx7 and miatas. In the game of racing, its not by how much power you have only. Its a ratios game. And if you take the HP to weight ratio im shooting for which is in the mid sixes. I should be just fine. the rest will be up to my driving. RX7 = 2200lb with driver 325 HP 13b PP (6.77 HP to weight ratio) Camaro 3200 with driver 500 HP 8cyl (6.40 HP to weight ratio) See the comparison

I have 285/30/18's all around using 18x10 CCW wheels (track use). At anything close to full lock the fronts do contact the fender liner. Not an issue for the track because you shouldn't ever be at full lock anyway. Street use it may be any issue.

I run 4x 285/30-18s BFG KDs on Enkei RPF1 9.5s with +38 offest on the street. Yeah they rub the liners but only at full lock or big bumps (and my liners are precious because...?), and you have to roll (or cut) fenders as mentioned, but you can rotate them for life and the car is stuck like glue. No rubbing on hard components and for 1400 shipped for the wheels the price is tough to beat with a stick!

Because on the left front a main wiring harness is attached just behind. If you wear through the top of the liner you then wear through the electrical wiring...

^EEK, I guess I need to replace my liner then! Is there any way to re-route the wires?

Sorry rob20rx7, don't mean to jack the thread.

nice car. looks like its going to be a real nice setup cant wait to see what it loks like when done

Any updates.... I'm dying to see the final product.

yea you gotta be carefull, I had a friend whos tire ate through the liner and then the wiring...lets just say it wasnt pretty ;)

im lovin it keep the pics moving!

Hurrryy

Post some update pics if you have any.

Track Car updates
 

here are some pics i shot today. I know i havnt posted any but as we sit. im waiting on the housings to get peripheral ported. (Put sleeve through them) and then build the motor. I pretty much have everything purchased already except for the plumbing which is my next step now. The brakes have been installed and brake line run and connected. I will next install the tranny with the dummy engine and start measuring the lengths for all the plumbing so i can order everything. im shooting for November to be completed but this all really depends on the engine builder.

Laters!

Have you made a cover yet for your fuel cell,Most sanctioning bodies require you to seperate your drivers compartment from the fuel cell.Looking good though

I am in total awe. :bigok:

My first born for your car?

Im sure for scca i will have to make a splitter for both the fuel tank and the oil tank. but for now im planning on running NASA to get the car set up. when im ready then i will finish teching the car for SCCA which will be the Points competion series i plan on running in. specificly GT2

Damn. There is definitely no mistaking that for a street car, haha. It's funny how small just the short block looks sitting in the engine bay with no accessories. Looks really good.

The car is looking great.

I hope you don't mind me easking a few questions.
Who made your engine?
Why the RX3 bellhousing?
CLR made me an engine, I see yours has the red color like he uses.
I hope he made yours.
PM me if you don't want to post.

any updates;i will love to see the car finish..................

Ok Here we go!
 

Got the Rotor housings in today. Along with Ianetti Ceramic Apex seals and also a set of Special Star Mazda Crank and water pullies. Next step is to send housings out to get machined and have Peripheral Port Sleeve installed.

Just for info, these are regular 13B GSL-SE housings and they will be machined around the area above the exaust to have a sleeve installed for Peripheral Port. I will post pics when i get them back. Hopefully around the weekend of the 28th.

For SCCA racing don't you need to run MFR PP housings or whatever other authorized housings? I thought that home made housings are illegal.

Well im not aware of that rule but that doesnt mean it doesnt exist. I can however assure you that i can not afford 2500.00 per housing. So if this is the case. I will be a happy NASA running MoFo.... LOL

Are you using old school plates with thoose rotor housing?? If so how do you plan on mounting the motor to the chassis?

Im using old school Front and Intermidiate plates and the rear plate will be a 3rd Gen Plate to mount to the subframe. As for the water o-rings. the engine builder uses double and then a special seal bonder to complete the bond. This works flawlessly on N/A Motors.

Cool :bigthumb:

In GT, any Peripheral Port Housing IS legal.

The correct name is "Alternate Rotor Housing"
The rules for GT as per the GCR states : The standart production or specified alternate rotor housing shall be used.

Many rule changes have come about in recent years once EFI was finally adopted for GT.

The GCR ( General Competition Rules & Specificationsm ) is available on lime at www.scca.com

It says approved alternates though, unless a homebuilt is an approved alternate I'd interprate the rule such that it's illegal.

I'd remembered this from reading Racing Beat's site where they said that their PP housings aren't legal in the SCCA, so if theirs aren't...

Anyway, it's probably not a big deal, they'll probably let you run with them anyway, and only the most anal competitor would protest over that. If not you can always run in SPO, or SPM (which is for the PP 13B?) in the SCCA.

If I may, I've run a 20b PP. Rx7 in SCCA as a GT-1 car for some years, in which time I've entered several Nationals, won a chanpionship, set a track record at my local track.....and no problems w/ SCCA even at a National level.

Always with "made up" Rotor Housings.

That's good to know. You never know how these rules will be interpereted, sometimes it seems to say one thing, but has grown to mean something else.
