Frankenbeater version 3

Post by ciper »

My 91 sedan is now converted to "RS Spec" with the following -

Phase 2 Ej25 block
Dished pistons that clear the deck
610 Thick MLS gasket
DOHC heads from 98 RS
RS intake manifold with Side exit Legacy harness and Legacy throttle body
WRX oil pump and engine mounts
98 Outback 4eat with 4.44 final drive :devil: (last of the phase 1 4eat and it was rebuilt by Subaru)
4.44 LSD mixed from female Outback and Legacy turbo diffs (carrier/stubs and driveshaft flange from Legacy diff)
02 WRX front brakes and Wheels
Real borla headers + stock RS cat pipe mated to legacy mid pipe and then modified RS muffler
93 Legacy ECU (thanks Jamal Spec lol)

Yes that is two widebody Impreza in the background :D

I'm thinking to use a wideband 02 sensor and configure the second output to emulate a narrow band sensor but with the graph shifted slightly so that the computer tries to automatically tune the car for better power during closed loop ;-)

This car burnt through the same exhaust valve on cylinder three on three different occasions. With the help of Thawa (yah rly) we believe it was a bad injector driver in the ECU.

I was sick and tired of driving on three cylinders and I had been gathering random parts from people so I built a 2.5 engine. The extra power made a previously ignorable problem noticable

I drive the piss out of my car. I take it over jumps. I thrash through the mud. This meant many worn out or broken parts. I once broke the headers in half lol. Before I was able to fixI wore out the front universal joint so badly that the two u shaped pieces were touching each other! This caused one hell of a vibration. I tried to use a driveshaft from a newer car and found out that it was a different length. We ended up cutting the end off both shafts and welding the new end onto my old one :)

The car drove great but had a major random failure. After driving normally for 150miles the temp suddenly shot up extremely high and the car died. I pulled over and assumed the coolant was gone,,, but it was still full! I tried to start it and it turned over very slowly (the pistons were sticking to the cylinder). It started and the noise was AMAZING to say the least. It had rod knock on at least three cylinders and more than one bad main bearing :o

Frankenbeater V1 consisted of a phase 2 complete shortblock with DOHC heads, turbo water pump and oil cooler, stock 91 computer, 98RS intake manifold, Legacy engine harness, Legacy throttle body and stock intake piping.

I crashed a White 2005 STi (with 2006 front end conversion) and we happened across a super clean 98RS so the entire wrecked car was swapped in. I could have as much of the RS as I wanted excluding the trans and heads.

Frankenbeater V2 was V1 parts but with a phase 2 block using "phase 1" pistons and I used an NA pump eliminating the oil cooler. I also installed the 98 Outback 4.44 final drive 4eat but left my 4.11 differential. (yes I installed the fwd fuse).

This engine ran great but I could hear this rattle sort of noise on rev up. It wasnt load dependant and didnt do it while cold. I ran the car on a lift and checked all sorts of crap and couldnt find it. I finally started unplugging injectors and the noise was diminished most on number three.

I tore into this block and found that the rod bearings were FARKED! They should be a silver color and they were worn down so that some were solid copper color 0_o

I removed the V2 engine, tore it apart, put it together and installed V3 all by myself.

The differential part screwed me up. Not only did I have to convert the carrier from female to male (which I have done before) but I got it all together and the mustache was upside down :( I fixed this and started to bolt up the driveshaft AND IT WOULDNT FIT!!! Come to find out there are two types of R160 mounting flanges. I had to remove the flange from my old diff and swap it onto the new one,,, which isnt easy since I had to use a puller to get the old one off and the night is supposed to be tightened to 145 ft lbs.

That's cool you got something worked out, and awesome that everyone helped you out like that.


Good thing you know your way around a Subaru with how you beat on them, lol.

Welcome back ciper. Glad to see your project coming along.

Cylinder #3 is last in line for fuel if I'm not mistaken... sure it wasn't just leaning out?

What brand MLS headgaskets are you using?

See here's the thing. Most people incorrectly calculate the CR because they dont take into consideration the bore of the headgasket (which is larger than cylinder bore) and that some pistons clear the deck while others are flush.

It should be equal to a stock EJ25D in the 96~98 Subarus. Subaru says its 9.7:1 but I get something higher. Maybe you guys can figure it out?

99.6 bore
79 stroke
46cc head (the EJ25D heads are actually modified Ej20G heads...)
14cc piston dome
.5mm over deck for the piston (guesstimate because I cant find the data)
101mm gasket bore*
1.3mm gasket thickness*

Resulting in 10.25CR ?

It was leaning out. I saved one of the valves and Ill take a picture of it. If you've ever seen what a meteorite looks like thats how the melted surface of the valve looks.

Subaru brand gaskets. The 610 and 642 gaskets are a gift from god and I can get them really cheap!

Sorry, should have been more specific. I was just wondering if maybe the injector was working properly but just starved for fuel.

The heads you're measuring CR on are carbon-free?

I didn't measure the heads myself but when I searched around multiple sources said they were 46. My heads are carbon free but they've been decked more than once so I'd assume the CR is even higher?

More pictures of the Imprezas can be found here including dyno sheets http://www.facebook.com/pages/Renner-Mo ... 7?v=photos

There is actually a third swapped Impreza at the shop that I didn't upload pictures of. It was a clean 98 RS with a headgasket leak and we swapped the 05 STi drivetrain into it. That specific car is currently for sale

I think I have figured out why frankenbeater V1 died. Recap - The coolant temp was perfect and then suddenly it shot up quickly and dropping to neutral didnt help. I checked the coolant level and it was fine and the system didn't boil over.

I was posting on Nasioc about removing the heater core http://forums.nasioc.com/forums/showthr ... ?t=1913750 and while looking over the FSM scan I figured it out.

Image

My heater core was leaking at one point so I took one of the hoses and routed it back to the engine. The hose was kinked which prevented any coolant flow. This meant there was no "equalizing flow" within the engine. It explains why when i poored water on the engine it sizzled on the head but not on the block. If you look at the diagram you'll see that the left head basically has no cooling when the thermostat is closed except for a miniscule amount through the throttle body hose.
