Hey everyone, some of you might recall that recently my motor failed on me. 2010 STi SE with 24k miles. Here is the original thread. TL;DR - My ringlands failed. Bad. Cylinder #2's piston is missing the entire side of the ringland (top & bottom). They easily came off after I pulled them out of the motor. Luckily they didn't break apart while in the car. There really wasn't any metal in the oil pan or filter.
Anyway, I've decided my build plan, builder, and tuner. I've been doing a lot of research to plan this out, and I think I have everything. If there's something not listed that I need or should add, please let me know. This is my first build so I may have missed something. I would like to try and keep this under $5k, but hey, you have to pay to play.
I took a 2 1/2 hour drive and dropped my block, heads and crank off at IAG Performance in Maryland on Saturday. After doing a lot of research, they seem to be very reputable, have good turnaround time, and can meet all my needs and exceed them.
My goal is a reliable, durable daily driver, but also makes good power. I'm not aiming to hit 400whp anytime soon, but I will eventually (I read the PSA and links). My car ran 330awhp on R/T Tuning's Mustang Dyno before, with intake, full catless turboback and Cobb Dynotune. I'm not really expecting this build to make over 350awhp, and that's fine...for now
Moving along, here is my proposed build as of now. I plan on reusing my shortblock and crank, but we will know for sure after IAG diagnoses everything.
- Manley Pistons (99.75mm)
- Manley H-Beam Rods (might do TurboTuff instead)
- ACL Rod & Main Bearings
- ARP Head Studs
- Perrin Air-Oil Separator
- Air Pump Delete
- Competition Stage 4 Six-Puck Clutch
- Gates Timing Belt Kit & Water Pump
- Oil Pump (What is recommended?)
- OEM Gasket Set
This comes out to a subtotal of around $3000 for the parts alone. Then there's also the other small miscallaneuos parts and fluids, which will probably add up to around $300-500. I expect labor to be aroud 15-20 hours (motor is already pulled and full disassembled), adding roughly $1500 in labor, making the grand total right around $5000. Then there is also about $500 to tune the car after it is done. So yeah, as you can see I'm already going over my budget. There's so many other little costs that I'm sure will add up as well, like towing the car to the shop.
I really want to do cams while I have everything pulled, but it looks like it's going to be around another $1500 to do that, and I'm having trouble deciding if that's worth it right now, seeing as I'm not really looking for significant power gains at the moment, I just like the way lopey cams sound.
Other possible mods I want to do in the future are:
- External WasteGate
- Walbro 255lph Fuel Pump
- Injectors (probably 1000cc)
- Boost Controller
- Perrin Front Mount Intercooler
- Of course a bigger turbo at some point
Some of those are pretty cheap and I might consider doing now, such as the boost controller. Since the boost controller and the fuel pump are pretty cheap, are they worth upgrading now for my setup, or can they wait? Since I'm not too knowledgable, I'm not sure if I should upragde my fueling system, or if stock will be fine for my build. I am also considering going Speed Density, but I might wait till I do the headers/UpPipe/EWG.
I know this is a lot, but I have so much going on in my life right now and its difficult for me to spend hours and hours trying to find every answer. I just started 2 new jobs, trying to get my PA ACT 235 Cert, and just got engaged and a place with my Fiancee right after returning home from my deployment. Thank you all so much in advance. You guys are seriously a huge help.
