I see the potential and thanks for info , but what has been made from the 3.0 NA? 325rwhp? Thats a magic number. Can the VVti be fitted to the non vvti head? Can you fit the vvti cams to the non vvti head? Less torque but more up top.
The turbo spec sounds great but will have the same issues as the 3S engine with weight,heat, build costs and with more than likely too much power for the application.

Go 2AR with a small turbo. All alloy 2.5l motor with dual vvti, same weight as a 4age. Good for 500hp with forged internals and more than 700 with sleeves.

TBH a race car driver could get anything out of anything.

dont forget im a amatuer at best just like Pete :-)



with hundreds of driveline options the simplest will always be the engine it left the factory with as you know.

VVTI components cannot be swapped around.

To get a 1MZ up to 300+HP in NA form is going to take some serious cash and it's then cheaper to go 2GR. However throwing a Turbo on the 1MZ is cheaper then 2GR.
 
2AZ is a good suggestion, killer little motors them.

Thanks for the input on the engine guys and its great to have something to think about. I will keep you updated on the progress.
Im looking forward to seeing the completion of the chassis ready for paint. Expect it will be black.

My point was, the V6 is just as good/quick as the Turbo option at tracks like Wakefield,Winton, Morgan Park but with less chance of problems if driven back to back by the same driver. PI, EC would favour the Turbo for speed and less heat management due to high airflow but a rear mounted turbo would hit the nail on the head in saving the heat issues with the current system.
I do appreciate the point of a standard factory set up, but a modified set can be just as good as long as its done right. Something I  personally have a lot of trouble with..but Im getting there! Things rattling apart is the biggest pain. If you can stop bolts falling out, your half way there. Until then, you almost feel like you own a Harley..man..

Is this going to be YOUR car or MARKS car. havent seen Mark on here for a while
Supercharged V6 for a change would be nice in a track car.

It was a joint venture which i stepped away from, but will be stepping back into it as Im going to add a reasonable amount of motivation,input and parts into the project. Once I got him started he didnt want to stop and really enjoyed himself. 
Hopefully Mark will be back on the forum but at this stage, Im waving the flag.
The engine comes down to cost and a 2GR SC would be out of the budget.
 
I have been in contact with another crew who are building a SW20 with a 2GRFE SC or the 2AZ for endurance racing. They asked for my input which Im looking forward to providing. They want ultralight SW20 so I will also cover the progress on another thread when it all falls into place. This will be ready for the MTC 2014 and W300 2014. Expect this one to be a very serious unit.
 
Trav, I love it! We ran the screamer stright to the road at the W300. Pete said it was shooting flames every which way. Pretty crazy.

I think you mean Aaron? hahahaha, who doesn't love a rediculous screamer pipe!
