Also going to need a new manifold cause the ones I have don't suit the larger turbo well (no room).

50,000 miles so far on factory sleeves, no excessive blow-by indicating cylinder distortion. Haven't done a leakdown test in a while, but the last one was good.

Do you think I need to get my IC piping welded? I could save about $500 just by cut and clamp. What worries my is the 20psi I will running. Open to suggestions

Focus_Sh1ft · 02-13-2013, 10:33 PM

Are you worried about blowing couplers off? My tC pushes 22 psi with silicone couplers and t-bolt clamps with no issues. I did have problems with a vacuum plug being blown off... That was fun.

Definitely opt for t-bolt over worm gear at that point.

cali yaris · 02-13-2013, 10:59 PM

24 psi here, no issues with silicone couplings or fittings. A lot of clamps would make me nervous though.

pimp my yaris · 02-14-2013, 07:59 AM

20 psi and my couplers are holding. Are U running a FIC or a standalone? My FIC is maxed out at 20. 15psi atmosphere plus 20psi boost runs to the top of the FIC map at 35.

Yoda · 02-14-2013, 09:47 AM

Running the fic still but if I am able to save a few here and there I will be upgrading to standalone. Garm did you have to modify anything to get your turbo to fit back there? Think I still have your manifold in my garage.

cali yaris · 02-14-2013, 12:23 PM

^ I remember having to clock it, and I insulated the firewall, but otherwise it fits okay.

Remember, we now offer plug 'n play AEM EMS + Boomslang harness. Best of all worlds, and certainly the way I would have done it.

Yoda · 02-14-2013, 05:24 PM

Ok cool I may take you up on that offer. My FIC is wired in gonna be a pain to remove .

Focus_Sh1ft · 02-14-2013, 09:55 PM

^ Just throw the bypass plug in and be done with it.

pimp my yaris · 02-15-2013, 01:59 PM

What's the price on that Aem Ems boomslang combo Garm? We need a YW discount.

Yeah but then he's stuck with the FIC sitting there. Gotta be some resale value there!

True. I wonder if AEM sells just the universal harness (and if so, for a reasonable price).

The thought of having to remove that harness after it's installed is worth no worldly sum of money to me for the effort involved, lol.

LOL i know right

Yoda · 02-20-2013, 01:02 PM

Question did anyone need to change to tolerances when installing the pistons? I think it says 35 thousandths but not sure if it should be more for my boost level

Bluevitz-rs · 02-20-2013, 01:09 PM

Piston to wall clearance?

Yea that.

Bluevitz-rs · 02-20-2013, 07:04 PM

It's different if you're using forged or cast pistons. Each has a different expansion rate so you'll have to do a bit more research to get it correct.

pimp my yaris · 02-24-2013, 09:05 PM

I went with the standard piston size. I beleve it was 75mm. I did not have a proper cyl. Bore guage. I have a little to much clearance. Noisy piston slap when the motor is cold. It gets a lot more quite when the motor is warm. It sounds like a old VW diesel. I have beaten the shit out of it with no problems yet. No oil burning at all. Its just sounds shitty when cold. Both Garm and blown xa said they have some piston slap noise. I beleve you can have some tighter tolerance on forged pistons as opposed to cast because they dont expand as much. This would explain my noise. I dont know what sizes you can by for custom cp pistons. I know 75 and 75.5 mm are available. Best to measure with a bore guage. And remember pistons are not perfectly round.
