I would like to see how strong the motor / clutch / tranny / fuel system / intercooler / etc are compared to what we are used to. So to find the limit we buy one and bolt a GT47 on there and start breaking stuff. Open deck motors ftw.

It is not an open deck motor, they modified the 4B11 for the turbo, it is now a semi-closed deck. It is also nice to see that a manual X GSR is only 60 lbs heavier than a IX MR.

What does open deck or semi-open deck mean anyways?

**JET** · 10-04-2007

Open deck means the cylinders have one big coolant passage all the way around the deck and it is not supported. 4g63 is a closed deck, with just the coolant passages open. A semi-closed deck will have supports going from the cylinder to the block, but still fairly open. It should be fine for high HP though from that aspect. That is why the Honda guys put a block guard in, like so:

That turns an open deck into a semi closed deck, the 4B11T will come with something like that installed from the factory.

Just search for pics of STi, Honda, and 4G63 short blocks. The 4G63 has a fully closed deck. Most Honda engines like a GSR(B18C1), D16, NSX, Type-R, later H22s, etc have an open deck block. To make decent power with the Honda engines, you need to sleeve the blocks, which usually involves totally boring out the stock sleeves and replacing them with a supported sleeve or one close to a semi-closed deck. The STi has a semi-closed deck design, which lets them handle some power compared to the WRX that has an open deck design and is a fairly weak motor.

The Honda guys stopped using block guards a while ago. They usually only made things worse, since putting them in distorted the cylinder placement and the sleeves often cracked at the bottom anyways. You can get farther on the stock Honda sleeves than people used to think 5 years ago, but if you want to run big boost reliabily you need to sleeve it or buy a closed deck Dat Honda block.

Thank you for the awesome answers guys!

pictures from Do-Luck this morning of the Evo 10 that they have in colloboration with ARC.

Parts for the car are already under development by both Do-Luck and ARC and they expect to showcase the car very soon, more than likely at the Tokyo Auto Salon.

Safe to say Do-Luck is continuing its development with Evo's with products expected to be released shortly for the Evo 10, we'll before UK cars arrive even, which is great news.

We can expect to see some Aero parts as well as strengthening , and cooling parts of course such as intercoolers and radiators etc.

Picture of a Ti exhaust in planning

I like the fact they have gone to a timing chain, and have eliminated the balance shafts.

No doubt, I have never had a white car that I cared about, but this may change it. I have always went with black or silver. A white MR with tinted windows may be in my future when I sell this house!

sleepydsm · 10-07-2007

I'm kinda disappointed with this car in terms of styling. I'm curious to see how the engine handles more power.

**Kracka** · 10-07-2007

I like the addition of factory foglights.

My car has fog lights! Just for the 7,8, and 9 they were integrated into the main headlight array. I like having separate fog lights though, looks cooler IMHO (a-la the HUGE ones on an Evo6).

Just to let people know, the white one is a GSR. It has black vents on it (hood and behind front wheels) and MR's have body color vents. The MR has better wheels, brakes and suspension, but the white GSR has the performance package to get the same ones. The MR also gets the silver grille and little chrome piece around the grille. MR also gets an upgraded interior and SST (think DSG with better tuning and options).
