2.4L EVO VIII motors ready to rock -
http://www.slowboyracing.com/estore/home.php?cat=5660
We have been running variations of the 2.4L block in our EVO IX rally car all year with much success, however the transition for the EVO VIII guys is much more simple without the MIVEC - We CAN offer this as well for the EVO IX guys, however we need to chat on the phone first to explain what needs to be done. We actually prefer if an EVO IX would like to swap to the 2.4L block that the install would be done here at the shop to avoid any complications.
A 2.5L version is also available, but takes about 5 weeks to build due to the lead time on custom pistons - a 2.6L version will be tested soon.
Check out the link, let me know your thoughts!

The 2.4l motor has proven to be a great performer in any 4G63 platform we have tested it in. For a street car, the 2.4l motor's added displacement is noticed immediately from the first crack of the throttle - The 2.4l motor will make 30-40 more ft/lbs of torque than your factory 2.0l at the same boost levels and about 15-20 more WHP depending on your turbocharger of choice.
Why build a 2.4l motor instead of a 2.3l motor?
1) Cost less to build as core motors are abundant unlike the expensive 2.0l cores.
2) Taller deck height by 6mm than the factory 2.0l block.
3) Larger bore size by 1.5mm over the factory 2.0l block.
4) Rally tested and mother approved - it will simply make more torque than a 2.3l motor.
5) Did you catch the part where it is less expensive due to the abundance of cores?
What are you waiting for?
You had better tell all your EVO VIII buddies that the 2.4l motor is the answer to their prayers! No longer will they have to worry about the typical lag issues related to small displacement street motors. This motor is a perfect match for the GT35R guys who want a wicked street car (yea I said wicked, so sue me- that will teach me not to hang out with people from the NE part of the US) and do not want to wind the motor out to 9k to have a little fun.
2.4L EVO VIII STG III race block
OEM 100 mm crank
Manley H beam rods
Wiseco HD .020"
ACL race bearings
ARP mains
Feel free to PM any questions to me about pricing or otherwise on this engine.

Care to address some of issues that might come up with a 4g64 block. Below are some of what i've heard.
- different length timing belt due to taller deck
- timing can't bet set straight up (cam gear marks to valve cover marks) due to taller deck
- standard alternator bracket not compatible
- standard water pump needs adapter plate or modification

#1) Yes, you will need to use a 4G64 timing belt
#2) Correct, adjustable cam gears are suggested - you are welcome to call in and talk to Josh or myself when timing the motor.
#3) Have to research a bit more, I have not heard my guys bring up this issue, I will check if an oversight on my part or theirs.
#4) We will send each block with our custom water pump spacer/ adapter.
All good stuff, thank you - as a reference - our shop would charge about $1,500.00 in labor to swap in this shortblock plus parts.

We made about 35 more ft/lbs of TQ with an EVO IX turbo with the 2.5L over the 2.3L. With the GT28RS we made another 10 ft/lbs of torque over the EVO IX turbo on the same motor.
2.0 vs 2.4 would not be much of a fair comparison in my opinion - but I am willing to work with a few people on price to give me good, usable feedback that I can use as well. I will only work with people with the ability to install and tune properly - keep that in mind when you email me. I will also work closely with you if you are local to our shop.
