So the flanges have a type of slip fit, with one end being conical, and the other being flared... The direction you have them, wont that create unwanted turbulance?
You're probably right. There's a reason I did it this way. I can't remember why exactly, but it was some "mechanical" or "fit" reason. I figure with the 3" tubing, there will be enough flow (plenty in fact) that the little bit of turbulance won't make a measurable difference.
Yes, the other male portion of the interface is rounded almost like the OEM Honda donut gasket, but it's steel, and part of the pipe. I thought I might stick it in a lathe and spin it with some valve lapping compoud with the down pipe pushed up against it to lap the seal a little better. Then again, I have these same style flanges on my truck headers, and as long as I keep the bolts tight, they don't leak at all.
Well I've actually been making some progress on the build over the last couple weeks, and figured some of you might like to see what's up.
I finally got the front wheels I ordered about 15 months ago. Remind me to never pay in advance again. With the 245/40-17 tires mounted, it looks like I'm going to need to find a bit more room:
I re-finished the engine bay so I was able to dump the motor back in. Things are looking up!
I also bolted the header with the 3" down pipe back in (as can be seen from some of the photos above). There's not a lot of room in there. I hope the header wrap does a good job of keeping the heat away from the oil pan and the transfer case
Here's a bit of an idea how much room there is in the driveshaft tunnel. The driveshaft is 4" in diameter, and the exhaust is 3" tubing with a 4" diameter resonator. It fits but there's not any room to spare.
More to come as I get more completed over the next little while. I told myself on New Year's Eve that I'd have it on the road by the end of March. It'll be tight but I think I'll make it.
Today, the car saw the light of day for the 1st time in about a year. No, it's not ready to drive. Still a bunch of work to do, but I HAD to get it out for a couple pics for inspiration and a chance to clean the dust off it.
Matt, the flares will be just fine. I'll need to do a bit more trimming in the front for slightly larger diameter opening, but I've found all the room I think I'll need.
They're 245/40-17 on 17x9 in the front and 255/35-18 on 18x10.5 in the back.
It's an Endyn M62 supercharger kit for a D series. The manifold is hand fabricated, and the throttle body is on the end of an extended and straightened S tube. I've wrapped the S tube with heat barrier tape, but alas, now I'll have to take it off to weld in the threaded bung for the AEM water/meth injection nozzle.
WOW! im blown away! so you just eliminated the front transfer case and used the stock rear diff? what obx diff are you using? and how much did that drive shaft set u back? its a nice piece!
yeah how much was that driveline if u dont mind us askin. even those nice lil aluminum adapters i see on each end good idea when i was building my rex i wish i would have thought of that.
Between the driveshaft, custom Drive Shaft Shop rear axles, OBX diff with the machining and mods done to accomodate it, and the various other bits and pieces that went into putting it together, I'm probably $3,500 into the drive from the transmission to the rear wheels.
I'm still using the RT4WD transfer case. That's the only way to turn the power 90 degrees from the engine/transmission to the driveshaft. It has been modified though. I'm still not 100% confident that it'll handle the power. I guess we'll find out soon. I expect to drive the thing here in the next couple weeks. Engine bay is getting a little busy, and I don't even have the engine wiring harness in yet:
It would be done by now if my wife didn't keep asking me to work on the house ( ). Spent the last 2 days doing this new entry door. It's wider than the old one, so I had to re-frame a little to make a bigger hole:
Well I fired the thing up today for the 1st time. It started within about 15 seconds of the 1st crank! It has a bad idle surge, and because the exhaust is so bloody loud (not all there yet, only 3" cat and 3" resonator, no muffler) it's really hard to tell if it's because of a vacuum leak or because the idle fueling is way too rich. I am using the map that I ran before with 560cc injectors, but now they're 720cc, and I re-sized from the original 240 to 560 to the new 240-720. I'm going to try taking some fuel out to see what happens. The header wrap with the header wrap paint was smoking pretty heavily as well, but that was expected.
I let it run for 5-10 minutes, and decided to try and roll it around my cul-de-sac. Down the driveway I went using gravity (a bit of a slope). I put it in gear and tried to drive. It moved an inch and then I heard a small pop and then had nothing. No forward, no reverse. I feared the worst. Could the awesome weld that my Government certified welder buddy did inside the transfer case have popped that easily? No way. Just then, my neighbor came out "to see the car" (which had been making quite a lot of noise for the last 15 minutes or so).
He was nice enough to help me push it back up the driveway and into the garage. Back up on the jackstands it went. I slid under and turned the driveshaft to see only the rear passenger side wheel moving. I popped it into gear to be sure everything was tight up front, and it was. Turns out it was the passenger side axle that had popped out of the diff, so the LSD was unloading.
There's also a small oil leak at the sandwich plate to fix and I need to figure out what's wrong with the wiring on my 2 datalogging sensors (oil pressure and fuel pressure).
I may be hitting the road with this thing before the end of the month after all!
Well it lives! The idle surge ended up being a rather large vacuum leak (ie: I'm a dumbass!). After chasing my tail for 2 days, trying all sorts of things to get it to run right, ignoring the obvious, I had a eureka moment later in the evening yesterday. I pulled out the box for my AEM water injection kit to get out the instructions to give them a read through (yes I do read the instructions from time to time). As I pulled out various items from the box, I came across the little plastic baggy with the injection nozzles. That's when it hit me - BAM - right in the face! A few weeks ago I welded the threaded bung for the injection nozzle on the back side of the intake tube between the TB and the supercharger. Guess where my vacuum leak was: the empty nozzle-less bung!
Out came the 200mph tape and voila: vacuum leak fixed.
OK, here's a little video. I took it with my iPhone and for some stupid reason, I did it with the phone upside down. Quicktime is smart enough to flip it, but Photobucket is not. If anyone knows how to turn it the right side up, let me know. And if anyone knows how to embed a video here, I'd appreciate learning how to do that as well.
ill be waiting... but while ive got you here, in your opinion (since you've had that trans open)... how comfortable would you be running with the front axles plugged (but without the mod's you've done to your trans)?
My only concern was that the 2WD/4WD selector sleeve would not be able to handle the power I was going to be sending out through the transfer case. But then that sleeve is not a lot different than say the 2nd or 3rd gear selector sleeve, so who am I to say it wouldn't have worked just fine.

gottcha... if it doesnt work i do have another trans in parts
You asked for it, here it is. The Wagon driving. It's short, but it runs. Still a problem with one of the rear axles though. As soon as I put it into reverse to back up the driveway to get it back in the garage, the axle popped out (again). I'm going to call Frank at DSS on Monday to see if he can do anything (make the end of the axle a bit longer so it stays in the diff).
My wife decided it would be funny to finish the video on the flowers at the front door. Aren't they beautiful?

I've got an extra set (male/female) if anyone needs it.
Yes, the other male portion of the interface is rounded almost like the OEM Honda donut gasket, but it's steel, and part of the pipe. I thought I might stick it in a lathe and spin it with some valve lapping compoud with the down pipe pushed up against it to lap the seal a little better.

Jaker, im sending you a PM

You can't embed flash on this forum, i disabled it for security reasons.
