ya im going to have a pump gas and e85 tune, and hell if i make over 500whp on pump i may troll around on that map and switch to e85 if i really need to do some damage

My tuner and i decided to go with a ERL sleeved shortblock with manley rods, cp pistons, and a compression of 9:1 for e85.

Just curious, has there been several motors in this car? I swear I remember an old owner of this car and he sold it. Due to a broken rod I think. Not sure if it was from a bad tune or what.

Not sure if it was from a bad tune or what.[/quoteIm the third owner of the vehicle, the first guy put the 35r kit on the stock motor and ended up blowing it up. He then sold it to the second owner because he didnt have the funds to fix it. the second guy thought he would only have like 3k in the new motor for some reason and put the car up for sale after having to put 9k into the motor. So when i got the car i started perfecting the build on it and when i got it to where i liked it a vacuum line popped off while i was wot and it went way lean causing the motor to have low compression in two cylinders. So this is where i am at now throwing a sleeved shortblock in it and building the heads.

Bummer on the low compression. ERL makes some good stuff, good luck on the build!

little update on whats going on with the build. decided against the erl shortblock as I would have been waiting even longer than I already am. so far all of my internals have arrived. I went with darton sleeves, using my eagle rods, 100mm cp pistons with 9:1 compression for e85, gscs2 cams, retainers, springs, valves, doing a perrin big tube equal length header, upgrading the fuel pump from 400lph to a 450lph. that's a general outline of the build so far, they did a light port job on the heads as well. my tuner thinks we will have no problem hitting high 500s to the wheels. the block should be back tomorrow from being machined. More updates to come!

Nice build coming along...don't take it the wrong way but since you went all out with sleeves and aiming for 500+ I would look into a better rod than eagle for that high hp like manley turbo tuffs,pauters or carillos just to name a few

no offense taken man, I had a lengthy discussion with my tuner about this. he was on the phone with eagle for awhile discussing what the rods can take. they are rated at 600whp at 9k rpms. we will not be revving it nearly that high. my tuner is very confident in these rods.

where'd did you end up getting the block machined at? did the shop helping out with any of the cost of the rebuild?

No help because the motor was not built by this shop, I got the car in north carolina and the motor was built by 42 autosports. The machine work on this motor is being done by one of the instructors at unoh. He does all of the subies and lambo's for covert.

My XTI with 264 Kelford's spools my Dom 3.5XTR like its a VF. I am going to overlay my current build with the Dom 3.5XTR over my stock EJ255 with the VF48 and I'll bet the stock build curve will fit almost completely inside the current build!
What do you think of the GSC S1 cams over Kelford and especially for 450-500whp using the Dom 3.0 XTR?

I am looking at a rev range to 7500-8000rpm or stock STI EJ207 Rev Limit.

I personally would go with Gsc s2 cams for 45-500hp..also perfect cam if you look to go up in hp in the future

I'm feeling so. Weak point is the tranny. Im just looking at what GSC states for s3, while kelford states less.

Do you have any graphs of that? I know the gsc s3 is 282/282.

GSC S3
Intake 282/282 11.3mm/11.3mm Lift

Kelford D
280/278 Duration, 11.55mm/11.00mm Lift


But for this engine, the GSC S2 and the Kelford C cams are appropriate. It just boils down to which one. The Kelford have more lift but the duration on the exhaust is less.

GSC S2
Intake 272 / 230 @ .040" / Peak Lift 10.7MM / Centerline AVCS
Exhaust 272 / 228 @ .040" / Peak Lift 10.4MM / Centerline AVCS

Kelford C
Intake 272 / 232 @ .040" / Peak Lift 11.50MM / Centerline AVCS
Exhaust 268 / 228 @ .040" / Peak Lift 10.7MM / Centerline AVCS

Ok I understand. I dont have a liken for AEM.

I feel the Kelford C can slightly out perform the GSC S2, but not sure. But I am leaning toward GSC, but Kelford have good history.

There both great companies don't get me wrong I have just seen many high hp subarus go with Gsc s2 or s3 over and over again

I sent you a reply to your pm to me. Is this for the newer spec c car with the ej207? The way I see it is; I think it's a toss up with the different approaches. I think more lift yields more early torque and more duration holds power further in the rpms. I'm sure they're close performance wise. I'd also consider that GSC is a US company and Kelford is Australian, you might have better customer service with GSC. Availability should also play a factor in your decision. What's more readily available to you?

My thinking maybe flawed but those are my thoughts on your choices.

There are ok. I saw the PM. Its a built engine into a 2008+ JDM WRX. EJ207 block with JDM WRX heads. I have no pics of the heads for the world. Its the 2008+ JDM S-GT.
