FWIW I used a big brass brush wheel to clean my rotors. Brass is perfectly safe on iron parts. MEGA CLEAN ROTORS!!!! For the tiny spots and edges, I used a Dremel with the paint stripping bits. They are kind of like hard sponge, and come in different colors. Finally, for grooves and other crevices, I used carb cleaner and old seals.

It's somewhat therapeutic cleaning rotors...

PS
Don't buy into the myth that using a brush will wear the cadmium coating on the rotor. That was temporary for a long time ago when the rotors were first made and they sat on shelves... Some people don't seem to realize cadmium has a lower melting point than lead. The coating is long gone by now.

You ain't seen nothing yet!!!!

The trailer will bolt to any FC, I just have to wire it up. So yes, if I get it tagged, then I will be bringing it. it passed the inspection, I just need to get to the DMV which is about 150 miles away...

Becuase i am a firm believer in every heat exchanger having it's own source of fresh air. It's why my coolant temps stay ~180 on the track, and my AIT's stay damn near ambient. I'll be using a fluidyne rad that I'm going to make into a double pass, but I need to fit the exchanger for the W2A intercooling infront of it. up higher which is why the flyidyne will be a double pass. If I stuck with an FC oil cooler, there would be a wall of heat exchangers between the nose of the car and the rad..... no bueno.

Yes, yes it is... I use nothing but old seals and a brass brush and lots of carb clean..

I usually do it with the radio cranked, but tonight I had the Ipod on... if anyone saw me it would've been embarassing... I was actually singing along :rofl:

Official update: 62 days left and not much done... Colin came by to colelct his parts so I spent a fair amount of time welding tonight, and then a fair amount of time on the phone... I did start cleaning the rotors and I did start working on the front iron... taking teh paint off. Luckily for me I put in so much time this week @ work, I'll be clocking out early and will have probably 6-8 hrs tomorrow night. Plan is to decide which rotors to use, finish cleaning up the center iron, port all three and tape them off for paint on saturday... then build build build on Sunday... so we'll see what happens.

Off to play a quick game of chess then back to the parts washer .... then there's a shower with my name all over it

What seals are you using in the rebuild? Were any reusable in that motor that you plan to keep in it (IE: side seals, corner seals, etc)

GL man - word down this way is snow on Sunday so you all are hosed :)

I am sure you'll have plenty of time to hate all over my RX-8 at DGRR.

I'll be sure to make a bed of rose petals for you and Paul to lay in while admiring your matching turbo verts. :grouphug:

Why not other TDI coolers? They are the parent company of Fluidyne. I have worked with them on a few big projects. Pm me if you want the details.

How do you find so much time to post and work on your car? Post pic too :) See you at the DGRR.

Stock 2-piece Apex Seals & Springs - Useable and will reuse
Stock Side seals and springs - Useable and will re-use
Stock Corner seals - Meh... they look ok at best. I'll probably snatch those from my coupe rotors
Oil Control rings and O-rings. Looked awesome and the rings feel brandy new. Re-using those.

I decided that I'm going to rock some S4 N/A rotors becuase I want to keep the stock S4 flywheel. The counterweights are the same so the engine will be balanced. Tomorrow Chris (our badass engine builder) and I are going to go through the stock of rotors we have and find the best looking ones. Not caring about bearings because we have a damn nice set of bearings waiting in the freezer we can press in if we need to. I have brand new main bearings in the fridge waiting to be pressed in.

So tomorrow I need to find rotors and get the bearings dealt with. I also need to press in the main bearings. Mic out the e-shaft. Go through about 50 side seals and hope I can find 12 that get me to min Mazda spec... If not I have 14 new ones sitting in a box that were bought for the coupe, I can snag those if need be because that engine ain't going back together soon and order new ones when need be. Paint the steels and maybe repaint the housings/front cover. Need to see how the color scheme looks after the steels are painted. Fun times ahead for tomorrow!

Whatchu talkin' bout man? We ain't getting snow, rain and maybe 1"

Psh... I'll do something all over the hood of your 8 :rofl:

Yeah, our 'verts don't match.... mine will be together in a year ;)

Hmmmmm. shoot me a PM, I'm curious what you're talking about.

Another benefit of FD coolers, they'er here and they're practically free ;)

I live off of a carefully measured amount of RedBull, coffee, Starbucks energy drinks, zingers and Omelettes... and it's time for my omelette :rofl:

And I have a strict, "I'll sleep when I'm dead" attitude.

It's just dicipline. Theres a solid 15 hours in a day that are useable.

I will post some pics tomorrow. Right now I do need to eat and sleep, work tomorrow and the gf is coming up, need to be rested.

Official update from tonight though, with 61 days left. Got the plates fully cleaned and prepped. Got the plates ported and got my nipples tapped in. Also re-tapped off the housings and front cover incase I do decide to re-paint them I can do it tomorrow. I didn't get EVERYTHING done that I wanted to, but that's ok, tomorrow.... err today rather, is another day.

Yea I trashed a set of bearings because of purple power, it attacks the coating or absorbs into the bearing and just destorys the bearing less then a 1000 miles on the motor siezed it.


End of story purple power can suck a whole bag of dicks.

Im also curious why your not using solid corners is that super secret titanium red bull fueled knowledge

Wow.... I dunno what the eff we're using, but it can't be purple power. We've never had a motor come back so short like that. I pulled them out, they look and feel fine, the only soaked for like 24 hrs, but Chris has said some of the really nasty ones he's let soak for 3 days and the carbon just falls off.

I'm wondering if it isn't shit that's getting caught in the rotors and infecting the oil system?

Atkins don't seal all that great from the start and CAN have starting issues. The ones from RX7 specialties are supposed to be VERY tough on plates.

The more I think about the more I think I'm just going to rock stockers. The only reason they broke was because I banged the plates. The rotors that go in will be clearanced so hopefully this doesn't happen again. Basically the engien that I build next for the coupe will be rockin' a super DUPER secret turbo if the BNR's don't at least get back what I made stock. So I'm building that engine in anticipation of over 500wheel. Rotors will be balanced, lightened, and clearanced so touching plates shouldn't happen and the need for soild corners shouldn't exist.

I think the guy who are having problems with purple power didn't dilute it. The MSDS says it has Complete Solubility in Water. I am thinking some people have been using it straight up, which may lead to the pitting.

Just found out that the guy you bought the block from swapped all the matching accessories off before he sold it to you hahahaha

(j/k, just a random pic i found, titled "engine swap for DGRR")

WOW!!!!! Thankfully I didn't get those mani's... that shit looks like it's on there THICK! gross....
