Anybody here running this motor? I am looking into getting one on order for my 2008 STI within the next couple weeks. Which compression ratio did you go with etc.

Comments -/+ are very appreciated.

Thanks.

higher compression really isn't that bad. if your tuner knows what hes doing then it might be benefical. although it is prone to detonation.

That's actually a great deal for $3k, given it comes with a new 09 Nitraded crank, Cossie pistons and new rods.

yes, an amazing deal and Jodie knows what he is doing. Not only does he build the motors by hand himself, but he also builds 6 speeds and has all the propper tools for 07 gearing conversions, ppg's, ect.

The block i am using is stock compression, but i decked the heads so im right around 8.5:1

Okay. They have the 8.2:1 and 9.2:1 C/R pistons. This is the last thing I need to figure out. Im running a Cosworth 9.2:1 long block in my track car. But not sure what I want to do in this car. I like the idea of the higher compression but not sure if it will be beneficial to me. Right now I am running the stock vf48 turbo. But looking to upgrade to a 20g or similar this summer. What are your guys thoughts?

I am also interested in this block, is it noisy? How about oil consumption?

Do you have e85 readily available? If you do I'd run the 9.2 without a second thought, otherwise i'd stay 8.2 if your running this daily and with low grade pump.

I almost bought this block prior to finding a v7 locally.

I honestly wouldnt bump the compression up if you drive the car often, or if your NOT planning on running meth.

As you know, higher compression is great for track use, when your using the right octane. On the street, on pump, its very prone to det.

At 8.5, my WOT mapping looks very similar to a stock compression motor with my size turbo, but cruising was a bitch to tune. I literally worked on my car for a month until I was comfortable enough to drive with out a laptop.

I'd go stock compression.

When i start it in sub freezing temps, theres about a minute of slap, then the motor sounds stock. My opensource doesnt even pick up any false noise!!!
This is probably the best part about having this motor, quiet as stock!

In 3k of driving, very hard at that, I burned less than 1/4 of 1 quart. Oil was about 2mm below F line.

Stock compression from my understanding is 8.6:1 maybe I'm wrong. Maybe Ill change my mind and get the 8.2:1 and deck the heads a bit to get closer to stock. I'm not really a fan of lower compression. I didn't ever think that 9.2:1 is that high. Sure how how different a Honda would be for tuning but there are locals here with 10:1 on pump running 500+hp. So it never made sense to me of why 9.2:1 seems so high.

I'll be running 91 oct. I do have e85 available close to me but that's really the only one near by. The rest are close to an hour away so not worth it to me.

Come springtime I'm thinking about going the rallispec route. At 5,000ft elevation and only running e85 I'm thinking the higher compression might be a good idea. For the parts and quality it doesn't seem like a bad price.

The STi is 8.2, so i guess your referring to a wrx??

If your comfortable with higher compression, by all means go for it. I just figured i would share my experience. No matter, the block you choose will be stout

I was told 7200 RPM limit (using stock heads) He said 8000rpm with the proper head modifications. But 7500 if you will be up in the revs for long periods of time. This motor is IMO the best bang for the buck compared to the other companies.

I have been emailing David Anton back and forth and he seems to be a huge help!

How much did you end up shaving off the heads to get the compression ratio up to 8.5:1? I am still 50/50 on what to go with as this will be my daily driver driven on pump gas only. about 4500ft elevation.

Im assuming with a proper tune 9.2:1 will not be a problem. But for sure wont work with an OTS tune.

The stock heads are not the problem, is the shortblock. There is people reving to 8K all day with the stock valve train, and with some simple single BC springs and retainers Turbo_mike revs to 9K +.

Can you find out what is the crank balanced to?

Yeah I can. My guess would be something like 10k .25 grams like most.

I take mine to 7800 in first, 7500 in second, then 7100 in all other gears.

not sure about the balancing, but ill keep you updated on how the motor does.

Turbo_mike also has an EJ205 crank. Huge difference in revving abilities.
