can you still smoke em both with the true-trac?     

Haha yuup! 

[twistedtoy92]

Hell yeah buddy! Thing sounds beast!!! Nice work

[Tungsten Slayer]

Nice

Thanks guys!    So the cat is back on.       I am praying to god that I can get a deputy to sign off on this ticket and avoid the ref. I have been told by someone who has been reffed three times that they always put a sticker on the back of the ticket in the box where a signature is required for the fix it ticket to be signed off. I was also told the officer would have explained to me that i will have to take my vehicle to the referee by this date and yadayada... My ticket does not have a sticker on it so a deputy is still capable of signing the back of the ticket. I was also never told to go to the reff nor was I given a phone number to call.  Im ready to get this over with.  I hate the system and I want out.

[Tungsten Slayer]

Don't let the man get you down Nation.  Give em hell. 

I want to hear how the turbo works while wheelin'!

[twistedtoy92]

Thats why Wa kicks ass!

Thats why Wa kicks ass!

And they have a lot of Sasquatch's.  I mean, lets not downplay the squatch activity...


Still waiting for the squatch emoticon.

I tried to get a 00 4runner gas tank to fit in my rig today haha.  It sits a little low... i also made a support bracket for the intercooler piping on the cold side.  My computer is down. So no pics

[Nation [OP]]

Hey guys, does anyone have a wiring diagram that shows the vss wires for the 84-88 sr5 instrument cluster? My computer is down and I've been coming up short on the old interweb on the phone..  thanks in advance!

[Nation [OP]]

I used the tacoma cluster which I think has the vss built into it. sends signal to the ecu. I had no vss code when I got my truck reffed. I had an EVAP code, a bad gas cap  , and no brake signal to the ecu. fixed those and was good to go

What was up with the "no brake signal to ecu" ? How did you go about fixing that?

[HogCanyonHopper]

   IIRC, it was just a matter of hooking up the green wire from the brake switch to the ECU.

[1985CRAWLER]

so what ever happened with the whole ticket situation? 

[Nation [OP]]

I haven't decided which route to take... in the process of properly installing the remaining smog equipment... worst comes to worst I pull the turbo and put er back to stock and get it reffed.. whatever.. up the value of my truck and have a badge of honor haha

[Nation [OP]]

Now that the oil return bung has been welded into the pan and the exhaust is done.. the remove and replace process of the turbo would only take the lesser part of a day... i just hope the extended manifold studs still fit the stock header. Which they should..

[twistedtoy92]

what a PITA....

[Nation [OP]]

I guess it's all part of the "game" haha

TICKET HAS BEEN SIGNED OFF. NO REFF

The VSS signal comes from the speedo on the older trucks. You can use that for the VSS to the ecm. That is how mine wired and it works fine.

By the way this thread has inspired me, i just got a great deal on a Borg Warner K-16-24 dual scroll turbo off an XC- 60 Volvo with 35k on it. Worth 25 bucks lol.

Love the build!

[Nation [OP]]

Thanks for the kind words! Yeah I am trying to figure out which wires off of the instrument to connect to the ecu

Do you have a build thread?

[n6dlh]

No, no build thread on it, at least not here. I have one on YT, but not really updated.

If you give me the year of your truck, and the donor truck year, i can get you the schematic for the clusters and powetrain. I have tons of repair info at my disposal.

You get that tach working yet?

The tach is working great with the resistor mod!  I have an 84 SR5 gauge with tach, donor is a 2000 4runner 4x4 manual 3rz COP (4 coil) That would rock. Gonna get this CEL to go away. Surprised the bulb has lasted this long haha

[Nation [OP]]

Anybody interested in a G 54 HD? MC built.. about 7,000 miles on it.

Hey the difference in in the wiring harness and colors what year is your truck, it is easier to decipher the schematic at the ECM as the VSS input.

[n6dlh]

Ok the problem I am seeing is the newer motor uses a hall effect sensor for the VSS, the hall effect is a digital signal that is sent to the ECM at 4 pulses per revolution. Now the problem lies on how the systems work. Usually on the hall effect sensor the ECM would send a voltage out on the signal wire, and as the hall effect is running it effectively grounds the wire. The computer see the ground as one pulse. The VSS in the cluster on the older trucks are just a switch that turns on and off, since one end is connected to ground I am assuming that the ECM is sending out 12v on the wire and is being grounded. I did not test this fact on mine, since the 97 and 89 had the same component test for the VSS in cluster, so I just hooked them up and called it a day.

Might have to check the VSS + wire on the ecm to see if there is voltage on it, if there is I think it will work fine hooked to the cluster, if there is no voltage, it is looking for voltage being sent by the transmission mounted hall effect VSS and the cluster will not work, well not as a direct hook up.

[Tungsten Slayer]

The 01' Tacoma has the VSS signal go to the speedo and then it is modified to a 4 pulse and sent to the ecu....

How much mula did you get that intercooler for?

[Nation [OP]]

Free 99. It had been sitting for a very long time.

[Nation [OP]]

If Anybody has a 2TR bell housing laying around for a 3rz / R150F swap id love to take it off of their hands.     

[Nation [OP]]

Parts to come in the next week:

1. R150F transmission (3.0 style, short 6.5" spline)
2. R150F to Gear drive T/case adapter
3. 23 spline Tcase input (total spline i believe) MC
4. 2TR Bellhousing
5. Exhaust cutout pre cat

[Nation [OP]]

Ill double check on that in a bit! Id assume theyre the same. thanks for the information. So you just cut the B4 (green with blue stripe) wire and tap it into the 3rz ecu vss signal wire and done?
