You are running the ej22e S/B with the ej205 everything else?

How does the combustion chamber volume of the ej22e heads compare to the ej205 (49cc) heads. Where does that put your static CR? Just curious.

Almost 1000 miles on the newly rebuilt ej257 in the RSTi. Blew up the stock RS radiator. Replaced it with a stock ej22t radiator (the core is twice as thick). Planning on swapping to a WRX/STi style Koyo V-series at some point in time. Also installed a P1 replica lip on the RSTi....wow what a differ...

The misfiring came back soon after the new tank of gas, back in mid January. I did a full inspection of the motor and found the FPR vacuum line was popped off. That did not solve the misfiring. I double checked the base timing and it was set correctly. Finally I removed the coil pack to test that an...

'let's just get 'em past the warranty period'

I've always thought the same thing.

If you figure out a CR that works for you with the 49cc combustion chambers, choice of piston and HG, then this setup will work great. The more important question is the the correct choice EM. Either a standalone or the 2.0L WRX ECU can be made to work. Both options will require wiring modification ...

When I ran the original ej236t setup last year, after the oil pressure issues and dis assembly of the block, the thrust surface was the only surface not destroyed, and looked brand new. IIRC, when I originally got the crank machined for 0.010" oversized bearings, the thrust surface looked untou...

Maciek, please elaborate a little more. I did some comparisons on main journal diameter sizes between the phase 1 75mm and the phase 2 79mm cranks. The diameters are very close in range as are the thrust clearance requirements. So, as long as the phase 2 79mm stroke crank was cast with a correct th...

I have been starting to develop a strategy for the ej236t rebuild. Doing some initial comparisons between the Phase1 75mm stroke crank and the phase 2 79mm crank, it seems that you could just drop a standard sized position 5 thrust 2.5L crank into the 2.2t block.....as long as the thrust clearance i...

For break in I used a cheap 5W30 for the first 20 min of idle. Now I'm still using a cheap dino 5W30 with Lucas break in additive....possibly 1000 miles at low load and 5.5K max RPM. Then I was thinking of running Valvoline conventional 5W30 or 10W30 for a few K miles while turning the power up. The...

And both cars up and running again.

Going to take it easy on the RSTi for at least a 1000 miles.

I drove 8K miles on sub 60 psi max oil pressure. Bad news. All bearings were worn as well as the whole crankshaft toast. The low oil pressure is increasing wear on the main and rod bearings as well as affecting your lifters. Since the oil system works as a whole, any bleeding in the system lowers fl...

I tested a revised assembly process last night. Original process was as follows: Cleaned all surfaces with microfiber rag and alcohol. Wiped surfaces with dry microfiber rag. Inserted the bearings by hand and seated by hand. Applied 1/4" diameter bead across the whole bearing. Installed rod on ...

I have done the same type of rev limiter bouncing in the RSTi, especially in 1st gear....sounds bad ass when it happens. That redline comes quick when you got some go juice....haha On the rev limiter settings, do you have it set up as a soft fuel cut or hard? I think mine is set to soft cut over 200...

There was definitely compressed grease under the bearings. A thin film, but observable shiny residue and noticeable to the touch. I even wiped off all grease off the rod before pulling the bearing out, to make sure it is not contaminated during dis-assembly. I seated them by pressing down on both en...

Spinning a fresh rod bearing got me thinking deeper about the assembly process and eliminating any root causes of failed bearings from the actual process itself. I disassembled a fresh crank shaft and rod assembly just for observation purposes. I wanted to observe what the bearings looked like after...

I have not had a chance to verify the bast timing yet. I will update the thread with the data, once I pull off the timing belt cover and verify TDC location to the mark on the pulley. The misfiring started to happen again, even at the newly set conservative trigger angle. I filled up the other day w...

Just before Christmas, I grenaded the #4 rod bearing on the fresh ej257. I was doing a pull from 20mph to 120 mph (2nd-4th gears), just baselining with my buddies 410whp WRX. The RSTi was a tiny bit faster at 20 psi, but maybe a little too much too soon (300 miles on motor). All bearings looked grea...

I will update this once I verify. I'm going to be gone for a couple weeks and won't have time until I get back.

For now I'm just running it on the safe side of things. But it sure is pointing in the direction of incorrect base timing.

I have not done a compression test yet. Vacuum seems good while idling. It's just the quick ramp up which is strange to me, but might be normal. The misfire and vacuum are probably not related. It's just strange how I notice all these things all of a sudden. Maybe the failing transmission was maskin...

Sick Wagon! Love it. My favorite body style for sure.

That view from your work space....wow!

I verified with the vacuum behavior with the standalone....blip the throttle. Immediately goes form 19 inHg to 3 inHg....a little strange, but maybe its normal for that car??? I did some logging and was able to catch the misfires. Break up happens at or right before peak torque, and sometimes after ...

Mechanical.

I will verify this with my standalone, just to eliminate the boost gauge.

I want to see what you guys think about the strange vacuum readings on my 93 TW. It is run by a Haltech standalone ECU and is running a speed density setup. I've been having issues with the car lately. I thought the skipped timing belt was the cause of all of the issues, but apparently not. I have n...

Sorry, never mind.....you are running a pull type clutch set up, not push. On the push style clutch setups, the TOB will not clip into the pressure plate. Have you tried clipping it to the pressure plate first, and then inserting the fork into the TOB tabs once you are close to mating the engine/tra...

I like all the comparison data. Nice that the performance is better with less boost this time around. The power output really gets put in perspective with the WRX/STi output curves. You definitely squeezed out a pinch more then I did on my 91 SS running E85.....by like 5 wtq and 5 whp. Great Numbers!
