Nice car here Narfle, plenty of parts stored up too. If you don't need that duct I know someone that does! Keep up the good work Your right, one thing leads to another on these babies and it's ok if you change your mind along the way. It's yours, have fun with it.

 

what size and typ battery is that? is it the typ that fits turbo Jeff battery tray ?

 

Thanks! Just trying to take good care of it for now. Sold the duct with the IC, but Pettit sells a stand alone duct that lots people use for various applications, including the Greddy.
Cool Charge Intercooler Duct

Here's an add that shows the two side by side: https://www.rx7club.com/3rd-generati...-duct-1068554/

Yes, it's a TurboJeff battery tray. The size is 51r, a common Honda battery size. All the feedback I have about switching to something smaller involves a batter tender. The 51r one has never let me down, even after sitting for a good long time with the alarm on.

 

After my one bolt of rust in the battery tray I was thinking of a "dry cell" or gel cell or even loi. Any suggestions or seen anything fit in the stock location?

 

It's old batteries that leak, mostly. If you mind them well, I don't think it will be a continuing issue if you just want to replace and maintain. I'm not aware of any full size replacements that are dry or gel (though I'm sure they're out there). The stock size is 35 class, if you wanna look around. Not sure what the exact code is. It should be on the battery somewhere. Those fancy batteries get expensive quickly. The stock intercooler duct may also shove some moisture in the battery box during wet driving, which probably doesn't help with corrosion.

You might want to PM TurboJeff and see if he has any extra battery trays. The fitment is very nice.

Otherwise Elite Rotary makes a smaller battery box for the PC680, IIRC. Braille doesn't list their batteries with common sizes, but you might be able to squeeze more power into the smaller format with a braille or similar by checking the measurements. They expensive, tho.

 

If you haven't done your Radiator upgrade yet... I just pulled a like new Koyo N flow from my CYM when I went to the Greddy V mount. Havent listed it for sale yet. PM me an offer shipped. I will make you a fair deal on it.

Mike

 

Thanks for the offer. I sold a koyo to pick up this Ron Davis unit. Although I'm having urges to buy the ARC radiator and have that instead....OCD problems.
HUGE PICTURES ALERT! Resizing: ain't nobody got time for that!








Also working on "upgrading"/replacing the FD fans and motors with RX8 S2 units. Just need to wrap up the wiring and get them swapped in.








Saw a sweet old Ferrari, too. Seemed like the real deal, and no reason to doubt it around here. Now, how to get that much moneys....

 

Nice

(radiator that is)

 

Man alive, I ordered the Mishimoto cause it is local but you make me feel cheap! RD to ARC! To each his own but goodness gracious.

I like your fan mod too.

 

My mishimoto rad came with the wrong size nipple to the AST line, so be prepared for that

 

Haha thanks for the info and tips. Hoping I can catch up to your build a little bit!

Thanks! Gotta find some time to try my hand at pinning the connectors, or get a good crimper for the fans.
The Ron Davis is hard to argue with, but the ARC has internal fins or "micro tubes" as they call them. And, it's slightly thicker with nice quality.
MICRO TUBES!!!

All depends on who you get it from

 

Touche. I read that post from them right after I tried installing mine. I got a good deal on it though 270 I think, bought some smaller diameter coolant hose and an Re-A AST so I could change the lower fitting on it. I've read some people like to restrict flow to the AST from the rad for some reason but I can't recall why

 

I did order mine from RP just because they "fix" them before shipping and because they are close to me. Not to mention Chris will probably be tuning the car from RP...

 

Here are some threads about it. The AST basically bypasses the radiator, so the restrictor in the stock AST is assumed to limit this bypassing.

Always wise to develop a positive relationship with your preferred shop and trusted mechanic. RP are good people. That's basically why I didn't go with Koyo. I like my guy Rick, he shoots me straight and does a great job. I follow RP, and I'd trust them too if I were in their region.






I'll teach y'all a trick. If you go to google and type in "site:www.rx7club.com" and then put your search terms after that, it works better than the forum search

Let Me Google That For You

Google links are wonky, but the link above spells it out in case I wasn't clear in my explanation. That site is fun when people ask you general or easy questions at work. I've had it sent to me a few times

 

That's a nice radiator and the RX8 fan upgrade makes me wish I did that with my build. My fans aren't bad but they are just starting to rust. Looks like something I will put on the long list to do at some point.

 

Messing around with de-pinning and swapping the connectors of my donor rx7 fan motors and the new rx8 fan motors. Wanna wrap this up before dropping in the new radiator, and using the stall time to debate about the ARC rad. A few thoughts:

1. The new connectors are nicer (and easier to de-pin). If you're not into being super stock/reversible, I would consider trying to swap rx8 connectors onto the rx7 harness. I'd, personally, like to leave my stock harness stock.
2. De-pinning the old connectors is a pain in the butt, especially if you've never done it before. I never have. Almost made me wish I had cut and crimped.
3. For the FD clip. After you get the yellow clip off the back, there's a plastic pin holding the spade in place, and there's just enough room beside it to pry it up with a safety pin. Then you can use a small slotted screwdriver to force the old spades out the back. After you get one out the rest are less of a mystery. It helps free up the wires to cut the wire cover behind the plug.
4. For the RX8 clip. Pry out the rubber seal. Pry our the orange cover, with an angle pick or similar. The clips holding the spades are more visible, and easier to work with. There's no wire clip on the back and the wires are more supple, so you can pull them out the back pretty easy.
5. Need to find a source for the FD-style spades to crimp onto the new motors.
6. Need to get some new, non-rusty bolts for the new motors, and probably some loctite for the fan nuts.
7. There's a washer under the FD fan blades. It doesn't seem to go there on the RX8 fans, so I put it on top of the new blades under the fan nut. Will revisit before buttoning everything up.
8. The wires match colors, and that's the common guidance for re-wiring, so just gonna go with that. It might switch which fan speed turns on when, but as long as they all turn on...
9. I only did one of each, so I can take pictures and remember which colors go where on the connector.
10. Saw more cool cars: an amphicar with valid boat registration(never even seen one IRL, pretty sure), and a nice blue bugeye.

Here's a couple threads about the fans:
Mostly working in this one: https://www.rx7club.com/3rd-generati...x7-fd-1085155/
Good info here, too: https://www.rx7club.com/3rd-generati.../#post12038066

I think this is mostly an aesthetic upgrade. The Rx8 fans may be slower, lighter, less amps, and with better fan blades to compensate. But, I got a nice new IC crossbar from Jim Ellis Mazda online, and I'd like non-rusty motors.
If they end up causing any trouble or not satisfying, I'll buy new FD motors, which are way more expensive as listed, if they're actually not NLA. Sometimes JEM lists parts you can't have, that tease.
I guess I'll have 2x both FD fan blades lying around, some non-molested FD motors, and an extra shroud.

 

You are doing good work. For all the effort and if you wanted to keep it stock reverseable a little easier you could have skipped the depinning and made yourself an adapter harness. Just a thought.

 

Thanks, that's a good idea. Been having trouble finding a source for the electrical parts. Open to help, if anyone knows where to get the stuff (or what to call it).

And, this thread: https://www.rx7club.com/3rd-generati.../#post12038066
Point here: 250 Housing Lance Armlock - ET type Connector with Tangless Terminals
for the s6 style connectors and spades

Picked up a bunch of s6 style spades from there(already have the spare connectors from the donor motors, but don't wanna re-use the spades), so hopefully I can crimp them on and swap the connectors. Looks promising.

From the other thread:


Also ordered some shiny hardware from JEM, including new fan motor screws. All this slow progress is killing me. Hopefully some new bolts and bits will be easy wins in the engine bay.
The weather turned nice over here, so need to wrap up the radiator business and go for a long drive ASAP.

 

Not having the connectors in front of me I would say to browse some sites that sell various Denso and Japanese connectors and see what you can match up.
Here is a start

Also auction site search. And many, many other online sites.

 

Have some of the s6 stuff on order to check if the "generic" stuff works with the FD harness.
Also found the rx8 s2 connectors, they're sumitomo:
??????:Sumitomo Wiring Systems, Ltd
??????:Sumitomo Wiring Systems, Ltd

If everything works out we could make some jumper harnesses. CycleTerminal is kindof dragging their feet on my order. So, might have to do some more sourcing there.

Here's another interesting connectors thread:
https://www.rx7club.com/1st-generati...ectors-877734/

 

Good work, sometimes getting started and figuring out where to look is the hardest part.

 

Nice indeed. Wonder if those connectors on that 09' thread are still avail? Those could be used 50 ways to Sunday! Super nice and the price with shipping was nice at the time..

 

BTW, the link to the 09' thread still works for Eastern Beaver. Lots of cool stuff there for a wiring geek.

 

Yeah, they seem cool. I placed a small order with them too, cause I hand't heard back from CT. But, then noticed the order minimum is $20(or maybe $10, confusing). Anyways, CT notified my they shipped my package of connectors and lances. Really hope it works out. Now I need a special crimper :/. Might have a gang of extra pieces if the Eastern Beaver order ships too. If everything looks legit I'll try to get those rx8 connectors too and make a jumper harness. The saga continues!

 

Dave,

Here is another good resource for connectors. I was trying to remember this site as it's where I've bought some connectors and a wide band in the past.
