First to boost the new 1GR-FE

[Torspd]

Makes me curious if the lower intake manifold is the same between both models? If that be the case , then most likely a swap of upper intake manifolds with the TB would be the easiest route. Unless the TB bolts right up to ours.

It is different, a one piece design, but it is kind of similar. I do not think the plenum parts will bolt right up.

When I take the throttle body off I will see if that will bolt up to the current engine or not. It is supposed to be larger, but I never measured it to see by how much.

I do have a 4.7 TB around here that is definitely bigger.

Here is some more info on the new 1GRFE:top::http://www.fjcruiserforums.com/foru...ine-redesign-2010-engine-1gr-fe_engine-1-.pdf. It's interesting it doesn't have ASIC , it has been discontinued. Also 5mm larger throttle body. I wonder if the crank is also stronger...... it shows that they lightened it up with less counter weights. Also shows the cylinder liner spacers.

I am going to have a brand new 2012 FJ in the shop Monday evening for a final test fit of the supercharger compressor assembly.

It fits the 4Runner perfectly, but the FJ had a slight hood clearance issue so part of the manifold adapter had to be redesigned. If it fits on this test fit we are going to start the production run!!!

Wish me luck!!!

Sweet! There's gonna be alot of happy new FJ owners out there...especially if you got the new ECU harness adapters available. Is it going to be like the one listed above or like the current mkIII Rotrex unit? If different, why the change?

 

[gotrdwoohoo]

Gadget, can you tell us more about the twin screw compressor?

Cant wait to boost this new xr! My 05 would have wanted it this way

Hey Gadget,

considering it's a twin-screw positive displacement SC, you must be running water-to-air intercooling, am I right?

You need to look out for the intercooler cores getting contaminated with engine oil and hindering heat exchange, very likely to happen with boosted applications. Consider an oil collector to be fitted in-line between the PCV valve and intake manifold.

May I ask why did you favor twin-screw over Rotrex? I hear Rotrex is far more efficient.

Whatever happened to this BTW?!

Still ready for production waiting on getting the ECU connectors needed for the UCON.

:beavbutt: hell yes!!!

Very nice.... a whipple.

 

[darthyota]

what about offering a trd upgrade package gman? for those with trd scs that have maxed them out but still want more power yet still want that down low power delivery that a roots/twin screw supercharger delivers

 

[Gadget]

You need to come drive my XRunner. How much wheel spin do you want down low?

Which event are you going to show up for??

[rennurx]

That's one thing I like about my turbo. No wheel spin lol. So what did the new motors come in? Is it worth a swap?

 

[ntinhri]

Vury nice!

BTW Gadget, I believe Bullet Cars of Australia beat you to supercharging the 2nd Gen 1GR-FE.

 

[Gadget]

Maybe, but I think our prototype was up and running before theirs was, maybe not.
