My new car!

Was bored today so I decided to drop in one of my Denso Supra pumps (the other one is for sale!!!). I got the OEM fuel pump out without much trouble thanks to some hose separating pliers I got at Harbor Freight. Things work AMAZINGLY.

Anyways, got the OEM hanger assembly out and I was shocked that the OEM fuel pump looks pretty damn identical to the Supra pump. There are really only a few key differences, mainly the model numbering on the top of the plastic casing.

Anyways, after managing to spill at least a quart or so of gasoline on my pants and shirt (I call that a success), got the new Supra pump on the hanger without much fuss. It's basically a bolt-in affair. Dropped the assembly back in the tank, buttoned everything up, cleaned myself up and went to go take the car for a spin.

It started up no problem so at least I installed everything correctly haha. It's funny because I was half expecting the entire map to be richer but it really wasn't. Of course I was still having the high rpm/in boost stupid rich mixture so I pulled some fuel from the map in those areas and took it for a spin. Now I'm seeing roughly 10.5:1 at high rpm in boost which is still pretty damn rich but not too bad, at least there is no more ignition break up from a 9:1 mixture haha.

Other than that the car drove beautifully expect for massive oil smoking from the secondary. I pulled into a gas station to fill up and the guy working there looks at me and says "Looks like you need some ring work".

I was confused and said, "Huh?" and he replied with "You need new pistons rings".

I chuckled and said, "Oh it doesn't have any pistons rings". Then he just tilted his head and gave me this look like I was a retard. Haha it was pretty funny. He was just some old redneck.

The only weird thing now is during tip-in on the throttle it goes lean then swings back to where it should be immediately. It's only for a split second but that's all it takes to blow a motor so I'm a little worried. I adjusted my "accelerator pump" settings via the Datalogit and it started to get a little better so I'll have to keep playing with it.

I thought you already knew just how alike the stock and Supra pumps are. FREAKISHLY alike, which is why I like it so much better than the Walbros. Takes about 5 minutes to drop it in, and I usually manage to not spill a quart of fuel LOL.

I'm not surprised it didn't make it richer at idle though. I believe the pump is just made to flow more up top. And the car is set up to run only so many volts at idle anyway, so it shouldn't be ANY different at that point.

And will people ever stop commenting on what another person needs to do with their car? What kind of work they need done and all? Because honestly, you OF COURSE know my car better than I do, right? I would agree with that in some cases, but most of the time if the person has a sports car you can bet they know more about it than you do. I can't stand when people do that. I'm just waiting for someone to tell me not to dump oil in my gas tank. God help that person.

Well I have a re-wired fuel pump with a relay so I've bypassed the resistor for idle/low load. But yeah I was thinking it should have gotten richer at idle. I double checked the model numbers and the pump I pulled out of the fuel tank is the OEM pump for sure, and the pumps I have are the Denso Supra pumps for sure as well, so I'm not concerned.

It doesn't really bother me, I mostly find it funny being a rotary owner, you know we get that kind of stuff a lot. We might as well be driving a spaceship. I've heard some funny stuff about rotary cars before, funny how most of it happens at gas stations :confused:

Funniest has to be riding in my friends half bridge FC and we get into a gas station and he lets it idle (brap brap brap) while he goes in to get some stuff and I'm waiting outside with the car. This guy approaches me and is like, "Your car is running real weird!" And before I can even say it's a ported rotary he hands me this business card for a mechanic "He's my brother, he can fix it for cheap. I guarantee something is broken." It was too funny for me to say anything I just laughed.

If you did the same fuel pump rewire as most people do (and like myself) it shouldn't bypass the resistor, it should just feed power straight from the battery to the pump but using the same operational setup as stock otherwise. I never was able to verify my Supra pump because the numbers were ground off.

Yeah I was thinking about it the other day. You know, with most people (the ones that DON'T know more about your car than you do haha), owning a rotary is like owning a dragon. They've never seen one in person but they've always heard about them and they're in awe when they finally see one LOL.

See, that would piss me off. "I guarantee something is broken"...yeah, because YOU'RE the mechanic, and how could I forget YOU built the car. Please. My only response would be something like "and I guarantee you're an idiot that knows nothing about these cars. Leave now."

^Haha I love your responses to stupid people. "I guarantee you're an idiot"

Well, essentially the resistor is bypassed because I have a wire coming off the battery to a relay and the relay is triggered by the stock fuel power wire, so there is no more resistor in the power line of the pump since the old power line (with the resistor) is now just a trigger for the relay. Hopefully I phrased that right haha.

I can't help it, I just can't take being around stupid people LOL.

Uh oh, that sounds a lot like how I have mine wired HAHA. And I was told it's still controlled by the stock system. But you are making sense haha.

I figured someone would like that lol. It's true though. One time back in NC, I was at the drag track and my buddy told me he saw two kids bowing down to my car, and it was STOCK lol. That's a bit much if you ask me lol. There weren't too many around in NC though, not near as many as there are here.

^Really? Colorado seems pretty damn sparse on FD's. I think there are under 40 registered in the State. But there seems to be a lot of people from NC on 7club at least haha. Plus, they have the climate that supports driving an FD nearly year-round. I wouldn't mind living in NC come to think of it haha.

Yeah I've seen way more FDs just in C Springs than I did in all of NC. I did like being able to drive it year round though haha. If you want to move to NC, make sure it's either Raleigh or Wilmington, just stay away from Fayetteville at all costs LOL.

I always enjoyed vacationing to the Outer Banks area and Kitty Hawk, but I think it would be impractical to live there. We should totally road trip out there sometime and rent a beach house, Eric.

Oh hey, here's an idea, how about we road trip out there about this time next year?! Or maybe we can leave tonight and stay over the weekend. No reason. LOL

Not to bash or anything, but I doubt both your cars would make it the entire way!

Christi's FC. Case and point

Well sort of. Not an FD, but you get what I'm saying

^I'm not sure if you're joking or not, but I bought my FD in Littleton, CO back in Sept 04 and drove it all the way back to Fayetteville, NC. It was almost entirely stock, with what I found out later was a slipping clutch, and who knows how many other problems. So you'd be surprised how far an FD can make it, even in bad shape. And I consider my FD to be in MUCH better shape than what it was when I bought it.

I am planning on DGRR next year (if it happens). I just couldn't go this year because most of my free cash is taken up by the wedding and subsequent honeymoon.

But I am seriously planning on going next year, so we should rent a cabin together to split cost. It would be fun to keep pushing further east and rent out a beach house in Kitty Hawk after DGRR.

Says the kid with a basically blown 6...want to take bets on who could drive further now :lol:

Oh I really want to go, and I already regret not going this year, but I'm really hoping we can make the trip next year. And I discovered this year that there are more than just the Nanthahahahala Village, so it shouldn't be too difficult to find a place. My NC crew always rented a mansion and we had a BLAST there, but we didn't spend too much time with the rest of the community that was there.

OUCH! LOL!!!!! But very well put haha.

My new car!
