Hey ALL, we've had some time off from working on the ISF. My customer has been busy and whatever direction we go next will probably happen over the winter on his car. I just wanna know what parts you guys would like to be built and designed for the ISF and/or any IS models. If any of those of you who will be storing your F for the winter would be willing to let us use it to design some parts, please send me a PM so we can go over what we are both looking for.

We are still in need of a donor car for our single turbo kit, my current customer doesn't wanna do it unless he can sell his Twin Turbo kit first. The final list price on our single kit will be 12K, but I am willing to do the first 5 for $9,500. The kit will be capable of producing 700whp with the proper supporting mods(built motor, transmission, and fueling). Please let me know if any of you are interested in a turbo kit or a built engine we have many great product idea's waiting to be put into action. I have everything lined up to have pistons and rods produced for the F. Again just waiting for someone to want more hp! If there is anything we at Elite Autosport can do for the ISF/Lexus community please let me know, I'm sure we can help!

An ECU chip to gain more horsepower. It's a pretty beastly engine. I'm sure the gained horsepower could be handled by upgrading the ECU. BUT, I hear that it's impossible to crack the ECU on any Lexus cars for that matter. It just sucks that, a BMW 335i could just gained 60-80 horsepower just by adding a vishnu chip or juice box, and pay little to nothing for that amount of horsepower and could run with our cars.

The reason the BMW can make that much more with a "chip" or tune is because it's a turbocharged car and they turn up the boost along with a tune. The only way to get that kind of power out of the IS-F is to have us turbo your car for you. :)

How about just more affordable everything. It seems like everything from exhaust, to intake, to visual mods, seem grossly overpriced. Sorry I was ranting..... if we add a turbo, won't the ecu need to be tuned anyway? Without the ECU tune the turbo will not function properly, (see all of the turbo setups so far). As far as the headers are concerned, I heard that the install would be very difficult do to.?

Bro, I'll be honest with you, I dont mind spending $9500 on a turbokit for my car, I believe whats stopping everyone is one main reason..... WARRANTY on our brand new 08-10 $60k car... Drivetrain on this car is not easy to come by and not cheap either.

Headers and pulleys, with the addition of intake/exhaust. The goal would be 400whp with just bolt on's.

I discussed with you earlier about an engine build, and I'm becoming interested.

What WHP are we looking at for $9500? You say 700whp but I'm guessing that's with additional modifications. Also, what's the likelihood of some type of malfunction? I use my IS-F as a daily driver and need it for commute, and really cannot risk a malfunction.

If business picks up, I'll definitely pick up a turbo kit.

While I agree that turbo is the ticket, what will you do with the ECU? Will you use a piggyback? Do your use Motec?

We'll look into these parts and see if offering a more reasonably priced option is viable. Regarding tuning for a turbo system, yes a tune is a must, and is no issue for us. The difference between tuning a turbocharged IS-F and tuning an NA IS-F is that we have the ability to pull timing(turbocharged application) but we do not have the ability to add timing(NA application) as you may need in order to make more power in an NA IS-F. There probably is a little power to be had by leaning out an NA car but not as much HP as most of of you would want from a tune.

As far as headers are concerned, yes, they'd be a tough install to say the least. The same issues that make the install of a set of headers tough, make designing and building a set of headers very tough. Which would make them expensive to produce..

Understood. But it's a Lexus. You guys bought them because they don't need a warranty:D.. That's what makes Lexus/Toyota what they are.:) Drivetrain isn't as expensive I we thought it would be for this car. If our quotes on a transmission replacement was correct, you can expect 4k to be the cost of a new tranny from the dealer. Considering the complexity of this tranny, we expected it to be more.

I haven't followed the NA route that closely on the IS-F, but that may be just out of reach. Speaking of pulleys, is there currently an aftermarket crank pulley available? If so, is it dampened? I'd hope so.

550whp. We don't foresee any issues at that power level for a daily driver. Our current tt customer has been daily driving his for a good amount of time with no issues at all. And yes, to go for more then 550-600whp, there would need to be other mods to the car/engine etc.

We'll be looking into NA mods but are not sure of the 400whp goal.

We use a specially modified AEM F/I-C. You can read more about it here:

What about a standalone engine management solution? Have you looked into this and the possible issues you might run into with stability/traction control and other computer functions?

A standalone is pretty much out of the question. I'm sure there is a way to do it but it would be so complicated with the CAN system on the car that it would be too expensive.
