Supercharger install

[boydmick]

Well, I finally saved up enough for the TRD supercharger.

After extensive research here, I was most concerned about being able to handle the crankshaft bolt.

It turns out that was not as difficult as I thought. I was hesitant to use the starter bump method so I made my own SST.



it worked like a charm.

Unfortunately I didn't have enough length to connect the TPS and IAC plugs and had to lengthen the harness. This was the single most tedious part of the install. All wires were soldered and shrink tubed about 8" over stock.

The only othe problem encountered was getting the 90 degree elbow installed between the plenum and the intake runner. I had to fight with the hoses for about 15 minutes before it finally fit.



This shot shows everything except the lengthened IAC and TPS harness.

I won't go into much more detail since everything has been covered here to death.

I will add that the seat of the pants perception was not as dramatic as I had expected. It sure does pull through the mid-range better than before. At the upper rpm's (3250-4800) there sure is a lot of commotion going on! There is a distinct whine from the front and the exhaust whistle people complain about stock becomes much more pronounced (even with my Borla exhaust.)

I only have 150 miles on it so far, I will report back after some more miles add up.

I'm also waiting to compare to my girlfriend's GX470 before passing final judgement.

So far, the jury is still out if the power is worth the cost and effort.

Great job!

Oh, also . . stay tuned for aux. gauges. Probably a new thread tomorrow.

Did you add the Supra Fuel pump? You need more fuel to go with more air to get the bang for the buck. Some even add another Fuel regulator for that, I have not as of yet. Not sure I will.

Let me know if you guys break up.

Looks like s super clean install.
CONGRATS!!

Adding the fuel pump is not an automatic addition. Adding a wideband O2 sensor and gauge is really the only way to figure if you are running out of fuel. If the stock pump can deliver the fuel at the regulated pressure when it is needed, then it is ok.

On the 97 truck we did now that runs a turbo and two extra injectors, the stock pump is enough to drown the motor in fuel if we fire the extra injectors to much.

Nice and clean! Welcome to the club.... It's much easiesr change lane on the freeway.

Boyd,

Can you tell / show me where these places are that need to be extended? I have it all apart right now and want to do it now for a later SC install.

Thanks,

My wires fit, I wouldn't go cutting and adding unless you know you need to.

Clall me and I will elaborate.

No changes other than what comes from TRD. I will be watching operating temps closely to see if additional changes will be required.

As a side note, drove up to Big Bear today and the SC pulled like crazy up the mountain. I did notice an increase in temp, but nothing extreme. I will be testing in Baja next weekend and I'll post back.

Let me know if you guys break up.

You'll be the last to know

She drove the Cruiser for a year and had to one-up me when she bought a car. (During that year: 1 radiator, 1 Head Gasket, me stuck driving a POS j**p Cherokee - she's a leadfoot)

On second thought, I'll let her drive your rig anytime!

They don't *need* to be extended, btdt. The instructions aren't real clear on this, it says to cut back the harness cover, it just doesn't say how far. I ended up cutting almost to the firewall, but had enough wire to get both the TPS and the IAC harness plugged in without being tight. I then covered them with 1/2in corregated plastic tubing.

Also, if you are going to do the extension, I would not use solder, use crimp connectors. There is a lot of vibration on that engine, and a proper crimp will give a better connection anyhow.

DT, looks a lot cleaner install than my used SC. BTW, I used the intake manifold plug (step 32) for the boost guage feed.

I totally agree with this. I'd put in a rising rate FPR first, then look at the FP resistor before I'd jump on the supra pump. My concern with too big a pump is that I've seen pressure problems because the return can't return enough excess fuel from the fuel pressure regulator. Here though, I doubt the supra pump really is bigger....

Normally, a bigger pump works well with bigger line. Otherwise you are really speaking only to possibly increasing baseline pressure, which is better addressed with a fuel pressure regulator anyhow. I would also doubt that a 3liter I6 turbo has any more effective fuel pump demand than a 4.5L I6 N/A motor.

A different pump may work, I doubt it's worth the investment.

Sweet - none of us in the OC will be able to keep up with you up to Big Bear now!

Where is the best place to buy the supercharger kits? I was thinking that these would be a good project for my two '96s for next summer. Is Toyota still making them or is there a dwindling supply issue?

I got mine from cruiserdan

Man Scott, you crack me up. I guess that's why Toyota used the same size of fuel lines and a fuel pump that pumps out more than 60 lph greater and can maintain more than 20 psi above what is in the Land Cruiser for their twin turbo Supra...

And all of those clowns using the Wallbro's and Supra's fuel pumps and swapping in injectors in excess of 500 cc's are just really in need of a good fpr and that's it...

Christo, what flow rate are the two additional injectors you have with the AVO? And when are you having them come online? I'm not arguing you can flood the motor but that typically means you aren't running enough boost, right

Mike, I do not have the specs on them, but they are regular ones that are used on Corvettes and such. I can get the specs if you need them.

We are running them between 5 and 12% duty cycle and the times where they come on are programmed on the map with load on one side (from map sensor) and RPM on the other.

the "C" word

I hate to drop the C word, but can anyone give me a rough idear of what it might
"cost" to add a supercharger? for an I6. 4.5

kazuma is about $3500, just for the part.

and how does an additional 110 hp translate to rock eating or
trailor pulling?? is that an additional, what, 40%ish??

I'm adding an ARB and Kaymar bumpers and need more poop!!!
already did cold air intk.
