would make the engine bay look a lil cleaner. just outta curiosity what are the cons of a push fan?

 

My only thing would be that it would be a restriction at higher speeds when the fan isn't needed, or at least that's how it looks to me.

So no one else has come across this issue before when swapping in a 13b??

 

Well in the meantime while I hope someone will have an idea as to why I don't have enough space to fit my trimmed Taurus fan...

In case I end up having to make it a pusher, anyone know if I reverse polarity on the wires, will it make the motor tfn the other way or is there a circuit inside the motor that prevents that?

 

Should be fine. You might have to remove the blades and flip them over too.

 

I don't think I can flip the fan over... its domed on the outside end...

Well I got some more work done today, cleaned up the wires and extended short areas. Put the battery tray in, installed the coils and engine bay fuse box. Not to happy with how the coils are mounted but it will work for now. Still trying to figure out how to fit the radiator with such little space, what other high powered E-fans that are pretty thin can I use? They'd have to be less than 6 inches thick.

 

The guys over here use mark 2 MR2 fans side by side as they are the perfect height for an S3 rad-not sure how that would work on an S5 or whatever but it might be worth a look.

 

Hey Guys! I'm back from the dead!

Well, not really dead... I got caught up in stuff and distracted from my Seven, eventually ran into the good 'ol lack-o-cash issue and project once again went on the ice. But I just started working full time at my dealership and bringing the seven back to life is the first step in my plan to buy a V8 4WD 4Runner.

Don't worry I am not replacing the RX7, in fact I am replacing the '93 S10 Blazer... but I need a second car so when I sell the current junker I have something to drive!

Not that many of you really care or noticed I disappeared...

ANYWAYS! Quick update is done with, back to the nitty gritty.

Waiting on my paycheck to come through and planning this weekend to work on the Seven a little. Have the harness in her and mostly everything done. Just need to pick up some engine oil to break her in, an Optima Red-top, and route all the vacuum and heater hose lines.

Still have an issue with the fan though and I could use some help with that if you guys don't mind.

 

nice build man, subscribed

 

Good job on bringing it back!! Subscribed.

 

I put a second gen rad in mine and put a volvo fan on it. The fan is a nice Bosch and it fit like a glove. The second gen rad is supper easy and gained a lot of room.

 

I run a S4 rad in my FB look at the other guys pics and at mine in my album. You need to cut the header pannel in order for it to fit perfectly w/o hitting anything. I even have my stock undertray in place.

 

Looking through your pictures, I didn't have a header panel to cut unless you mean that short 1-2 inch bit from the edge of the hinge brackets.

In any case, I ditched the S5 radiator in favor of the stock radiator I pulled from an '83. But if you look at the pictures I showed, the E-Fan won't clear the water pump pulley and I can't trim the fan down any more...

 

yup. thats exactly what i mean. that small *** area needs to be cut out.

 

Hey guys, long time no post. Lot of stuffs come up in the past few months, quick recap.

~Working Full-Time at the dealership
~Taking a Tue night class to get my degree (in colonial American History... OMG could I have picked anything more dull... )
~I just bought a new (to me) 2004 Toyota 4Runner Sport Edition V8 4WD and the mod bug has dug deep on this future Trailblazer (Picture/thread https://www.rx7club.com/1st-gen-general-discussion-207/im-alive-really-i-am-944766/)
~Got sick for over about a month (high fevers 102+ consistently and other bad stuff. lets just say that if it wasn't for Vicodin I wouldn't have been able to eat and drink during those few weeks...)
~and to top it all off; some jackass thought it'd be a wonderful idea to see if his pellet gun's pellet can occupy the same space as my cat's eyeball. (If you're wondering, yes they can occupy the same space, but the cat will not be happy) so now I am medicating her and taking care of her hoping she won't lose her eye or go blind due to infection.

So the basic story so far as you might have guessed from my other thread is that I am on rather inflexible deadline...

My stepdad, bless him has been patient with me and the Seven but understandably after almost 2 years of seeing the car not running he's not too happy. Mostly because I am using the parking spot for the house we rent right next door to store it and some new tenants want that spot. So basically the car hasn't been touched since about March and its so close! I'm hoping I can hold him off until the end of June... I just have no where else to store my car (I can't afford to store it somewhere...) so if I can't get it running and registered by roughly the end of June I'm gonna have to find her a new home!

Now then! Sorry about the gargantuan post, I just figured some updates where in order. I just ran to the junkyard today and luckily found an old GSL-SE to snag the radiator supports from, which should help my cooling fan issue.

So here's the to-do list as of now:

-Install and wire in Taurus cooling fan
-Install the battery cables, splice harnesses together to eliminate double relays.
-Wire up the FC Fuse boxes.
-Fill the Transmission, Engine, Cooling System, and gas tank with fluids.
-Cut and install all the vacuum lines.
-Alignment
-Fabricate a 3" exhaust system from collector back (Cat & muffler, possibly pre-scilencer)
-Find and install a battery

It looks like a bit, but really more detail stuff than anything serious... The biggest problem is the exhaust system. My college's welding shop has been closed all this semester since December to accommodate remodeling and won't be done until the Fall semester (around end of August/Sept) so I can't weld in my own system like I planned.

Now this wouldn't have been an issue as it was planned to fab and install it in the fall, but my stepdad is leaning on me to get the car not only up and running but registered before then which throws me in a bit of a pickle... Between car payments, and some stuff that was already set aside for the 4Runner I can't drop a grand or so to have a shop fab up and install me an exhaust system.

So yeah... That's whats up so far, once again sorry for the long post.

 

You could shorten your list somewhat to meet your short-term goal (running, registered):

Reinstall clutch fan
Reinstall original exhaust
Skip the alignment til after
Borrow a battery

The wiring and vacuum lines you pretty much have to do.

 

I'd love to do that Divin' but there's a couple problems with that...

~The exhaust was scrapped with the old wrecked car after they stole the Catalytic Converter while I was rebuilding the car, (stated it in like the first three pages IIRC... ) and that was for a 12A not the 13B I have now...
~When I got the shell it had no radiator supports or radiator and when I bought the engine it had no clutch fan because the PO had switched to a E-Fan...

The last two are easy, I should be able to get at least a half-dead battery from work (Most of the batteries at work still have 350+ CCA even though they got replaced) to use temporarily. And if I get it up and running, the dealership is less than a mile from the house, so I'll knock the alignment out on a lunch break or day off.

Unfortunately, the GSL-SE Radiator Supports weren't short enough to get the fan to squeeze in... I'll try trimming down the fan shroud some more tomorrow, but for now at least the cooling system is ready to get filled up.

 

Quick Update as of 6/20/11

What's been done:
-Routed most of the vacuum lines for the rats nest and so on, some minor coolant lines and such still need to be connected.
-Bolted down some bits that were loose

What needs to be done:
-Need to thin out the duplicate relays I have
-Fill fluids and bleed brakes and clutch
-Still F#@&!n' with the Taurus E-Fan and still not able to make it fit right for some reason... don't have the tools/fabrication equipment to make new mounts right now, so I may try snagging an actual GSL-SE Engine Bracket and see if that will fix things... probably sometime this weekend if I can find one.
-Grab a battery at work.

Comments/Questions:
~Anyone know how truly important those green vacuum delay valves really are? I'd rather not have to go find some at the junkyard if I don't have to
~Its like 90 degrees here lately and bright as hell, so not the work environment I want to play in when I already put 9 hours a day in a giant concrete oven wrenching on cars!
~Oh right, I am still alive, lazy but alive...

 

I feel your pain man. On the vacuum delay valve this thread should have what you're looking for. https://www.rx7club.com/2nd-generation-specific-1986-1992-17/one-way-check-valve-939142/
Long thread short just scrap the valve, you won't be flooring the throttle with a cold motor anyway, right??? Glad to see you back finishing the project, I had wondered what ever happened with the build.

 

Oi, well my B-Day is tomorrow... (yay for me I guess?) was working on the Seven earlier today, just buttoning stuff up, got most of the vaccum routing done except for one or two hoses for the secondary throttle butterflies, and I think i am missing a couple hoses on the intake manifold; the diagram doesn't show any hoses there but I see vacuum nipples...

Bolted the ECM down to the passenger side footwell, covered it and then started to install the HVAC system. bolted down the throttlebody and upper intake plenum...not much else, have had a splitting headache today.

Honestly... as close as I am, I am starting to seriously doubt I will get the car up and running let alone drivable and registered anytime soon. And what's more, if I do get it running, I just don't know what I will end up doing with it. My life has changed a lot these past couple years and I just don't have the time and money to split on a second car. I barely have time for myself let alone anything else these days and I just don't have the space to store a second vehicle let alone one that isn't running. I am starting to consider the possibility of just selling what I have done now and coming back to rebuilding an RX7 later in my life when I have more time and space.

Truth be told, if I had enough space, I'd love to pick up the 12 Rotary Engines I have been offered a year ago (offer still stands as long as I pick them up) and just rebuild and sell them... but I just don't have a garage or storage area to work and store the engines let alone my RX7.

Sorry for how scatter brained this post is, the headache is messing with my train of thought right now...

 

i just want to say happy birthday and a sweet project going on redoing a 7 from the ground up is impressive looking forward to the finished product
-kyle

 

Happy birthday. Tough choice. So close. Good luck. Great work so far though :-)

 

Nice build thread man! Just went through it all! More pics please?

 

Why not ditch the rad mounts? Or jus trim them shorter to move the rad forward? You could always cut away however much is necessary & use L-brackets to connect it back to the original mounting spots...all you would need to do is drill holes.

 

Anything new with the car? Hope all is well man!
