Default ej205 - 2.1L - stock turbo

I'm building a 2.1L Manley stroker EJ205 for a friend. He bought a used 2005 SAAB 9-2x in TX and tried to drive it home to Alaska. During that trip the engine spun two rod bearings. That was a bad day.

Anyway, the car is in my shop in Seattle with the engine on the stand. I have the 2.1 short block done and am working on the heads now. I'll be doing some mild upgrades on the heads including BC stainless valves, new BC springs and stock retainers.

My actual question regards the turbo, intercooler, and injectors. Can I keep these components stock? I know that I'll be leaving some power on the table but the goal of this project is a fun daily driver with some better bottom end and good mid range. There will be no racing.

Here are the mods so far:

Manley 2.1L stroker kit
rotating assembly fully balanced
STI 11mm oil pump
ARP head studs
Perrin up-pipe
Walbro fuel pump
KillerB oil pickup
06+ STI oil pan
Brian Crower stock size valves
Brian Crower valve springs
K&N Typhoon Intake
Perrin crank pulley
Stromung down-pipe (still working on fitment issues)
GrimmSpeed EBCS

I'm planning to use the Cobb Access Port and a tune from PDX Tuning.

Thanks,

Patrick

sounds like a neat build. You should be able to resuse the turbo, intercooler and injectors..but with the added displacement you will max the turbo quick for being small.
Work with what you have, set aside for a bigger turbo and injector set.

I also have a 2.1 stroker. With a stronger bottom end why leave it stock. At the very least you should upgrade to a vfxx turbo and some 565's. Yes you can use the tdo4 but they really wake up with a bigger turbo and injectors.

I'd love to find a good used VF39 to put on this car. That and an STI intercooler and pink injectors and this would be a pretty fun car.

I'll let the owner of the car take on those projects. He was looking for a good AWD car to run in Anchorage instead of the F150. He's already into the car for $9K plus the $7K for the overhaul and other repair parts (tires, brakes, axles, gauges, etc...). This car turned out to be a real lemon.

I've run EJ205 with 2.1 stroker and I've loved mine,with right turbo will be fun and you will gain something like on spool up and on the top end

Here is on our one with MDX321T

I just picked up the heads from the machine shop. Now for some assembly work and setting valve lash. Still waiting for my new valve springs to arrive.

What are you setting your valve lash too? Also are you just purchase maps from pdx tuning or are you going to start the motor from stock ecu settings and then trying to tune it. Would love to know. My motor goes to the machine shop this weekend and am wondering on where to start tuning it.

I will be setting lash to the settings as indicated in the tech manual. I plan to get a PDX map prior to startup. I will not be starting on the factory map. I have more displacement and the compression ratio has changed from 8:1 to 8.5:1.

Valve springs are here ('bout a week ago). I have one head assembled.

I got worried that I forgot the o-ring for the oil pump. I pulled the water pump and oil pump. Guess what? The o-ring was there. Oh well. It was for piece of mind.

I had my heads done at Action Machine in Shoreline. I just had them machine the seats, resurface the heads and clean. I took them apart myself and am reassembling them now. This is a budget build so I didn't want to get crazy. The machine work was ~$210.

Default Bucket Time

Someone please help me out with buckets. The largest I have is marked 516. When setting my right side exhaust I get measurements of .406 .406 .406 and .457. What buckets do I need to buy to bring the gaps to .35mm? What does the 516 number on the bucket indicate? Is that 5.16mm? If so then I think I need three 521's and a 526.

I have my right side intake done. The left side is done except for one. I need a 508 bucket to that. I also need a 508 for one exhaust on the drivers side.

So I need six buckets and I can move forward.

I ordered the buckets tonight. I hope I ordered the right ones. I did mic a couple of the unused buckets to confirm the numbers were what I thought they were.

Still plugging along. I actually have the engine back in the car as of this evening. Now I need to get it all hooked up.

I ordered a Cobb AccessPort v2 today. I will be getting an eTune from PDXTuning.

I did some research on boost management. I decided to add a GrimmSpeed EBCS to the system since it was getting a tune anyway. That is on order plus a black Perrin turbo heat shield. Forgot the the stock one wouldn't fit my new downpipe.

I have the MAPs from PDX and the base MAP in loaded in the ECU.

I'm having some trouble getting my new downpipe lined up. I may have to do some minor cutting and welding to work it out.

I'm really close to having this thing running.

Default Problem

I started the engine and it ran great until I noticed that I was pumping oil out onto the ground. It looks like it's coming from the front of the left head. There must have been a plug there that the machine shop removed. Does anyone have a photo? I need to find one and I assume a crush washer to go under it.

Hopefully I didn't do any damage to the internals. That would really piss me off.

Hopefully it wasnt gushing out and just leaking out, because if its leaking then you know the internals were still getting some type of oil

Can you be more specific about where the oil is leaking? Tube with banjo bolt? Small hole in head? Big hole in cyl head?

There was gushing for sure. I did get the engine shut down the moment I realized oil was coming out.

I found the missing plug and installed it. Oil is topped off and it starts and runs leak free now. I do have some clean up to do on the engine and the floor.

My oil pressure gauge reads 90PSI. This seems high. I'm running Castrol 5W30 full synthetic oil. Should I be concerned?

Here is the plug that was missing.

You should have pulled fuse number 11 and cranked the motor over to prime the oil system. If you would have done that you would have seen the leak before you started it.

I actually did that but couldn't get any pressure. I did some searches of this site and learned that I should have pre-primed the oil pump. I pulled my oil sensors and they were dry.

Several people reported similar results and ended up starting the engine to get pressure.
