What exactly is the deal with sc on '96 Tacos? Ive heard its something to do with the ECU, they were changed in 97 or something.

Has anyone done a 96 or earlier Taco or is it possible at all?

Car and Driver had a shootout of tuners and one came with a Toyota Truck with a camper. It was turbo charged. It blew a cylinder in the competition and drove home on 3 cylinders.

Definately possible, lots of reading for you on that:

Yeah... like Jamie said, a LOT of folks have S/C'd that engine. Not a problem, but to do it right, there's more to it than bolting in the S/C.

Check the link that Jamie's posted. It's where 97.3% of us have started.

I looked at the link, didnt talk about the '96 Taco. If you look at the applications for the TRD SC's its always for 1997-up Tacos and 96 up 4Runners. Just wondering why '96 Tacos are excluded.

If we're talking about the 3.4L 6 banger, then it's the same engine that's in my truck. The S/C bolts on the same, the fuel delivery issues and fixes are the same, the timing issues and fixes are the same.

Drop a line to Gadget at URDUSA or through his private site above and ask.

Yup talkin 3.4 here. Thanks for the replies so far....

As Mark has stated, the supercharger will fit with no problem. The problem, and the reason TRD and Toyota says it won't work on your 96, is that you and have a different ECU. On the earlier model ECUs like yours, 95-98 year models, the ECU continues to try and trim fuel even in boost. This is unacceptable because under boost conditions, the ECU is still trying to get the fuel mix to 14.7 AFR giving you very lean running conditions doing definite damage to your engine. The 99 and newer ECUs don't do this. However, you can still run a supercharger safely if you use URD's fuel kit that is designed for your year truck:

Read the section about the earlier trucks and you will see what I mean.

I understand, but I think its more than just that. If you look on Ebay at SC's for instance, you will notice the application on all of them is 96 up 4Runner and 97 up Tacoma.

I think I will throw the question to Gadget or maybe he may chime in.

TRDOLMAN

Well, I have told you the answer to your question but if you doubt me then continue searching. Gadget will tell you the same thing I did.

What does that have to do with this?

And I'd listen to the guy with 300+ whp on his Taco

Cool, just want to make sure before I go spending $3k.

Before you drop your money on the supercharger, check with URD and make sure they have the fuel kit for your 96. The supercharger will physically fit the engine but it is imperitive that you have URD's proper fuel controller for it to work right. A good fuel kit is a must in my opinion for any supercharger application no matter what the year or ECU configuration.
