And why don't you call a tuner up and ask him on a tuned car how much difference there is between 91-93 octane. I garentee there is more than you think (I know from experience), but since you obviously have tuned with both 91 and 93 octane I am sorry that I didn't ask you first!!

I'll make sure to keep the same thing in mind when not needing someone to provide spell check advice.

It's an SR20, hence the "140" compression numbers on stock internals, PowerFC, and red "SR" logo next to the post title.

Wayne, you're zero for two on this thread lol.

Sileighty_85 · 01-27-2009, 06:42 PM

*kingkilburn* · 01-27-2009, 10:59 PM

It could need new rings, valves or valve job, bad gasket some where. . .

Did you have the head checked out before you assembled the engine?

GSXRJJordan · 01-28-2009, 12:10 AM

HEAD GASKET.

Power Enterprise/Apexi/HKS/Tomei.

JeremyR · 01-28-2009, 12:57 AM

apexi headgasket.

thats all you need to know.

then hit up steve shadows. i think he is in the aliso viejo area???

bardabe · 01-28-2009, 01:06 AM

yeah definetly get a head gasket and hit up steve.

TheRealNighthog · 01-28-2009, 01:22 AM

A problem that I have noticed with BC cams is that they were not designed on the proper centerlines for just a drop in situation. You need to cam gears to play with them. My favorite cam for "just drop straight in and make great power" is by far the Jim Wolf S4's

ka-t_180sx · 01-28-2009, 10:39 AM

anyone got a headgasket for sale????

Om1kron · 01-28-2009, 12:29 PM

best bet is to buy new man, I would never put a used head gasket on my car... hey man at least it's running right now. whens the last time you checked the coolant and everything?

Def · 01-28-2009, 12:44 PM

You have to run right on the ragged edge of timing (on 93) to hit 300 rwhp with only ~16 psi up top on a T28 and no cams. If you can hold 18 psi up top then 300 or more is pretty easy.

I'm thinking they left a little bit on the table, but this is a good thing. "Really high" numbers for a given boost and a jagged power delivery line mean you're getting phantom knock. Engine might last like that, or it might knock a little bit more on a hot day and smoke a ring, it's a gamble.

I've seen a few dynos on here that look like they kept adding timing in until the motor stopped making more power, which is not the safest thing to do on pump gas without carefully monitoring the knock sensor, and most shops don't do that.

FWIW, I made 300rwhp/275-280rwtq at 16 psi on my GT2560R(T28) with stock cams and a FReddy intake mani. I normally took a degree of timing off in boost for street driving, and another degree off at the track and lower boost for safety.

I would drain and refil with new coolant just to make sure that it's still semi sealing correctly and it's not mixing water with your oil.

Before you go throwing good money after bad and spending time on a Head Gasket, you should have your shop do a LEAK DOWN Test and see if you are losing from the head/intake side or the block/exhaust side. this will give you a better idea of what you need to do instead of basing your repairs on desktop/keyboard diags.

Just my two yen.

ryangreg · 01-28-2009, 08:05 PM

^^^seriously....

what are all you retards shouting "headgasket" at this guy for when you have no fucking Idea.

more than likely it needs a valve job, but needs a leakdown test done to verify.

*kingkilburn* · 01-28-2009, 11:30 PM

I would be thinking valves as well.

ka-t_180sx · 01-29-2009, 02:36 PM

thanks guys...im a get a leakdown test...

ryangreg · 01-29-2009, 02:40 PM

as for everybody who shouted headgasket, suck a fat dick seriously
