My apology I did shim mine. I spin it to 8900 without any issues. Granted it might be me.

Yeah, I'm using a 11mm and I'm still at 7,250. My tuner might push the redline back if I went with a bigger turbo. My whole engine was balanced and blue printed for it though. Because my tuner was thinking about possibly spinning my engine to 8,000 rpms. But, my turbo isn't making anymore power over 7,250. So, it is what it is.

Didn't you get a bigger turbo, like a DOM3 or something...??

as of right now im still waiting on my engine to get torn apart to see what the damage exactly is. The parts that i listed off that are going into the engine build are subject to change. As for the pistons and the compression ratio, once my motor is torn down and i get the call back ill discuss it with him.

For the record I'm not doubting your builder/tuner, just don't wanna see someone stick alot of money into a motor and only use it for a street car and once in a while a race car...

Yeah, I have a custom CHRA on my Dom 3. My tuner is saying this turbo doesn't make more without knock over 7,250. So, he kept it at that. He said if I go rotated or something bigger than the Dom 3 he can probably get more out of the top end. Again, my tuner tunes for drive ability and not numbers. I'm sure I could get him to flog the crap out of it....but, he wouldn't be happy with it. He did a pull at 28 psi on my turbo and it was making over 400 wtq, but he pulled the plug because he didn't like what he saw.

i understand where your coming from. at this point idk if i will be putting in cams. i had a talk with Jeff Perrin for a while and he said hes making over 450whp on stock heads no problem. im just trying to look at this project from every angle. yea i want a fun daily driver car i can do some fun driving in, yet if there are things in the build that i can do without i have no problem removing them.

Yeah most people don't realize the ability of the stock heads, especially STi heads. I run stock 2.0L WRX heads on my 2.34L with Spec C cams and have made pretty decent power from them. I know of people sinking thousands of dollars into a car and it is money just wasted since they will never use the full potential of the motor. You could use that money for other stuff....like beer..

just a quick up date: The block has been striped down and everything checks out and all the parts have been ordered.

cp forged low compression pistons
acl bearings
gsc stage II cams
H-beam rods
perrin header
oem gasket pack
moroso oil pickup tube
timing belt
water pump
11mm oil pump
oil (break in and pro tune)
oil filters (break in and pro tune)

just need to give shop $2,000 to have my block sent to the machine shop for machining and honing (6-8 weeks) then once it gets back it will take another week to put it all back together and then a couple hours to tune.

i should have my car back up and running by the end of the year.

update

I called the shop yesterday to check on the status on my engine build. It will be done at back at the shop from the engine builder on the 4th and it will take roughly a week to install. that weekend i will have my car back with the break in tune. oddly enough its on my birthday weekend...couldnt be timed any more perfect then this.

Just be aware that BC springs aren't unknown to kill valves. There are many tales available on the internet.
