My 12a with the Mikuni 2-barrel pulls like a sonofa compared to the stock Nikki.

Congratulations!!! That is one serious fb. I'm finding out how much work goes into just rebuilding an engine and putting it back in let alone swapping a whole different one lol. Goodwork!

I keep watching the comparison video and it just reminds me how quick my old T2 was... I think I'm sold on doing the swap. Got a long road ahead of me. I'll be looking forward to your wiring write up cause I know I'll need it along with many others lol.
Also thanks for reminding me about the writeup, I'll be working on that tonight if I can get the time.

The 12a is a beautiful engine, don't get me wrong. It's just it feels underpowered for the chassis it is in. It was probably equivalent to a current V6 Camaro in its time, in the mid power range for the price. It' purrs and is very cool but just doesn't give me the goosebumps I wanted

Congrats! |
12a's can definitely be fun, no doubt about that. Once you have 200+ ponies and boost though it's hard to go back lol.
Austin - this thread did turn out really well - you're better at documenting what you're doing than i am apparently lol. I'm impressed that you followed through on my advice etc and also impressed that you got this thing done so damn quickly :) |

I do love the feel of boost though. My dad has a 98' 300ZXTT that's bone stock w/ the HICAS system and it's an absolute joy to drive. We are planning a build with it soon to turn it into a road race car. I am hoping to grab the old turbos off it and use one on the 12a. |

I am probably around 290-300 rwhp (probably being a little generous here). I personally find my 85' 12a more fun to drive. Granted it doesn't have the power but it's so damn light and maneuverable it feels faster.

I think when I get my 12A right, I'll be quite satisfied... She's to be my daily driver. Just think, 20-30 years from now when I can't see far enough to get my driver's license any more, Someone will be thrilled to get a stock vehicle to do their mods from scratch... With whatever technology is available then! I have to say, Your upgrade looks like a ball! You've made a huge gain! :worship:I'm impressed. But, I'll just get my 12A "right" and be content. I'm certain you've been MORE than an inspiration to others! You've probably provoked a few. Congrats!

In that case I can heartily agree with you that a 7 would be much more fun to drive even under 12a power. That person I eluded to earlier with the Mustang may be me and I couldn't barely stand to drive that thing after getting used to the 7. There's just something about how these cars drive that cannot be matched... The 300ZXTT is truly a pretty car and looks like a blast, I'd love to drive one someday.

Well unto a point. They handle great until they dont :D Yeah, I'm not going to be pushing this thing too hard on stock 13's and open rear end with no rear sway bar as it is now. Once LSD, 5 lug, larger tires maybe I'll try some more fun things out :nod: Updates as of Late: FMIC, Optima Red Top, Optima battery box, relocation to storage bin, and some other parts will be ordered tomorrow and will be installed as soon as I get them all in so that I can close the hood. Pure Evil Genius I've now put a few hundred miles on the car and have loved them all. Just within the last few days however I've had some dastardly evil thoughts cross my mind... We set record lows here in MN for July, like highs of 60's and lows towards 50's and with 6 month winters (winter described as having snow on the ground, could be extended to 7 or 8 months with temperatures reaching freezing at night) you're always thinking about getting ready for winter...winter......winter storage! I have some huge plans and updates that will be revealed within the next week or so after figuring out some final details on this school year. Just be assured that they are going to alter this car for the better, faster and stronger :bigthumb: |
Shrimp - I agree, a 12a would be more fun than a Mustang, but that's because Rx7 > all other cars lol :P
Yeah man, glad I could help you with the swap. One of these days I'd like to make a "how-to" thread about it. Currently most of the swap info is hidden within build threads like ours. Would be nice to have a how-to like I see a lot of on the Subaru forums I'm on. Oh well, maybe someday. |

Updates as of Yet This week marks the two year anniversary of the car and myself. I went to my fiance's grandpa's house for his birthday (he's the one who bought the car and sold it to me) and thought I'd take a few pics. 1st Pics I Ever Received Of The Car Attachment 664546 Attachment 664547 Attachment 664548 As She Sits Attachment 664549 Attachment 664550 Hanging out with some buddies, mainly working on the Monster Audi Attachment 664551 Attachment 664552 FMIC piping kit with everything necessary for installation Attachment 664553 From turbo to TB 2.0" to 2.5" 90deg silicone elbow 2.0" t-bolt clamp for turbo 2.5" BOV adapter kit with BOV 2.5" 12 piece piping kit with 18x12x3" outside (12x11x3" core) FMIC and silicone adapters and clamps 3.25" to 2.5" silicone reducers for piping to FMIC inlet and outlet 2.5" ~2ft extra pipe GReddy throttle body adapter AAAAAAAAANNDD the bombshell. I was adjusting the TPS on the car since it felt a little off. Sure enough it was at 0.7v at idle and I adjusted it up to 1.0v. While driving it would cut out at about 3,500RPM while starting to make boost. I was testing this and found that it kept doing it so I adjusted it a little more and tried again. I boosted it and let it go back to idle and it died. Like completely died. While cranking there's no oil pressure, even while cranking with the low oil pressure problem. Car won't even fire anymore. Seriously scared I wrecked an apex seal and will need to move the rebuild date up much much sooner than expected. You don't want to run too rich or lean, but I don't think adjusting the TPS to the correct voltage would have done that. Of course, I don't know what happened just hoping that wasn't it. I adjusted that other screw that's on the driver's side closest to the throttle body (not the one with the 8mm nut securing it) before it happened but I wouldn't think that would have done it either. I didn't check AFR's after the adjustment so that worries me. Will be testing compression first thing when I have time. Headed down to a Dr. appointment tomorrow for a long needed surgery consultation and will try to make enough time to come home and test compression to make sure it's still good. If it's not I'm not sure what will happen with the car right now. Returning to college after the summer off really messes with your brain. |
The fact that it isn't firing makes me think its not an apex seal. My buddy blew 2 seals in his S4 and it still started. If the compression is good perhaps the ECU?
Whatever it is hopefully you get her diagnosed and back on the road quickly. |

FMIC stuff should all be here and I'll start installing that no matter what here real soon :egrin: |

Well went out and checked on the car for less than 5min last night. Found out that this fuse was blown:
Attachment 664327 So I replaced the fuse with a spare 60a fuse I had around (couldn't find a 30a) and tried cranking the engine over. The car sputtered and fired, to which I got quite happy about. Then I noticed smoke coming from the wiring harness on my side of the car. I quickly ran and unhooked the battery and that's how the car sits right now. I'll have to go over and through each wire to figure out if there's another fuse blown that's causing the melting wires. It's the same wire coming from that fuse to the Main Relay that was melted and I'll be double checking each and every fuse in the car as well as the grounds. Hopefully I don't need an ECU or anything. |
I'm sure you'll figure it out fairly easily. Still, it's stories like this that quickly dampen my occasional bouts of turbo envy. Keep at it!
|
So you're saying there used to be a melted wire before the swap-in?
|
Glad the engine is ok, Same question as Iotus, was the wire already damaged previously? Makes me wonder if the main relay is bad, or has a loose connection internally that's shorting out...

Essentially: I boosted the engine and it died when trying to idle afterwards. I tried cranking it for maybe 3 or 4 minutes total right after it happened thinking I just killed it with an ill-adjusted idle. I saw some smoke but thought it was just from some water I spilled on the engine when filling the cooling system. Pushed the car and left it for a few days. Came back and saw the EGI Comp fuse was blown and replaced it. Again, while cranking the smoke appeared from the wiring. I unattached the battery just to be safe and have left it again. While feeling the wire I can feel that it is melting going to the Main Relay from the fuse box EGI Comp fuse. I'll go through the whole wiring system tomorrow hopefully.

I have tomorrow morning off and it's pretty much my only day in the last 2 weeks and for another week. Wednesday I'm technically off but I'll be doing other things besides car work. |
My wiring issue:
I tested it today and it is the W/L (White/Blue) wire that goes from the 2nd gen fuse box labeled "EGI Comp" to the W/L wire in the large plug of the main relay. I tried cranking it and it melted the insulation for the length of the wire a second time. It's only that one that's out too and I already have sent money for one from a member with a good iTrader score so hopefully that can get here at the beginning of next week so I can install and test it. By then I hope to have the FMIC mounted and ready to go as well as some other things I'd like to see done in the car before too long. New windshield installed! Now I don't have to look through a huge crack anymore and can actually enjoy the drive http://i1052.photobucket.com/albums/...psd5f2ef59.jpg Hole through radiator support for FMIC piping - made it about 3.25in just for future needs up to 3" pipe and I'll be lining the hole with a hose cut in half so it doesn't scratch or cut into the silicone adapter that will be there http://i1052.photobucket.com/albums/...ps92326278.jpg Top view of TB side of the piping - only way I could get it to clear the brake lines that made any sense. Luckily I got the kit with 12 pieces in it so I have all sorts of bends and interesting ways to run the piping http://i1052.photobucket.com/albums/...ps70a5510d.jpg Pic of the TB adapter and its piping http://i1052.photobucket.com/albums/...ps5fe0e044.jpg Will try to make some more progress here over the next few hours before work - we will see! |
So it was the main relay that was fried?

Some progress on the FMIC and finishing wiring tonight, pretty happy with its direction so far! Wrapped up the wires near the firewall and cleaned them up tremendously so they actually look presentable now http://i1052.photobucket.com/albums/...ps75c1597e.jpg Took out battery tray and cleaned up the wiring on that side a bit http://i1052.photobucket.com/albums/...psf609525b.jpg TB side without battery tray and cleaned up wiring http://i1052.photobucket.com/albums/...psc731d800.jpg How the engine bay looked after I couldn't take the mosquitos anymore http://i1052.photobucket.com/albums/...ps4010e22e.jpg |
Accidentally posted here. Woops.
Well, personal update just because then! I'm going back to the University of Minnesota - Twin Cities campus here starting the day after Labor Day. I'll be living with family closer to the campus with the garage that I have stored my car in the last two winters. It's very small and cramped but if I play my cards right I can use it enough to swap out to an FC subframe and do a full 5 lug swap. This will be among other things but I won't disclose them until later when more things are decided. I also have to have a surgery over winter break so I wouldn't be able to use the almost month long break to get car stuff done but that's whatever. |
Got the FMIC and piping all finalized tonight!
Will be making brackets out of flat steel tomorrow morning probably and getting it all finished up. This is what it will look like though, pretty happy with it. http://i1052.photobucket.com/albums/...psfb402fdb.jpg http://i1052.photobucket.com/albums/...ps90786393.jpg http://i1052.photobucket.com/albums/...psd8fb18e4.jpg Also reunited my hood with my car, such a glorious reunion :nod: http://i1052.photobucket.com/albums/...psf2b66d65.jpg Can't wait to get it running again! :bigthumb: |
Where did the battery end up?

Yeah buddy :)
You're gonna flip when you feel the extra power that intercooler adds, and reduction in turbo lag from that blow off valve! HUGE diff! |

Austin, does it keep poppin the same fuse? or is it random intermittent 80s wiring?
must be grounding out somewhere and should not be too difficult to trace if you follow the wires out of the fuse box. What air filter is that? specs on the sizing too? I need to replace mine soon |
