+1 It doesn't make sense to do that in the US because you can just get an IS350, with much more hp and torque, but in Thailand it's a different story. People don't usually buy car with big engine most of the cars on the street are under 2000cc due to import tax and fuel economy.

Also, cars over there are different from the US even if it the same make and model. It's crazy what people have to pay for watered-down luxury cars over there.

 

any updates? its been almost 60 days !

 

Lms sells the kit with out the procharger for$1900 & you can buy the prochager ati c2 $2000 or used for less ,but its 60-80hp maxs 7lbs

 

where in thailand are you located? planning a trip out there april 2011 would love to check this out!

 

Bangkok sir.

The Rotrex in UK ship the Rotrex C38 to my local shop. That was too big model for my car. So, they keep it and order the proper model for me.

 

I'm assuming that you're leaving the factory functions such as A/C to the Factory computer and using the HKS to control all the engine parameters such as fuel, timing, and traction control right? Why did you choose the HKS vpro instead of the Motec? With the Motec M880, you can pretty much use it to control the entire car.

 

Yes. I gonna leaving factory function with oem ecu.

The reason that I choose HKS F-Con V-Pro instead of Motec M800 because at here the unit + Hardness + Tunning of Motec M800 was double price of HKS F-Con V-Pro.

I also had to spend another budget for a set of low compression CP forged piston (9:1) and a set of Pauter X-Beam Rod. because the stock CR was too high for boost over 7 psi. (I plan to boost around 1 bar)

The function that come with HKS F-Con V-Pro was enough for my daily use with some weekend track with friend.

 

The price that I got for a set of Pauter X-Beam Rod (6-Cylinder) was $1,290 plus shipping and a set of CP Forged piston for $950 plus shipping. (Price quote from manufacturer)

Anyone know the supplier who can offer better price for me?

 

BTW the IS engines pistons are a very specific shape to make the stratified direct injection charge work properly- are the low compression pistons taking that into account?

 

not sure if it helps, but here are the pistons in GM's turbo DI application


and wiseco's version of the same piston.


anyone have a pic of the toyota's pistons?
Edit: I saw a diagram of the 2GR-FSE pistons and they kinda looked like these

can anyone confirm this? If so, doesn't seem like a big deal honestly.

 

Just got back from CP. They can make a custom set of low compression Piston for 4GR-FSE. They need the oem part for draw a blue print.

 

i can prob beat that price, pm me when your ready

 

Here are pics of factory Pistons & Rods as Pepo requested;

 

As I use this car for daily life. So, can wait for 4-6 weeks. So, I order a new parts and ship to the manufact for sample

 

Normally, pistons are the same in other car. But for 4GR-FSE was devided into 2 side. (Right Piston & Left Piston)

Then CP Company need both side for make a new custom Pistons.
