you need to find someone locally to tune the car, you are going to hurt the engine sooner than later.

it depends on how the A/F looks... do you have a wideband, or any means to check it?
I wouldnt be racing without a good tune, but thats just me I guess..
and I ran C16 this weekend at the track, but im tuned for it..

Re: (Topdawgg)
it had ran at 18 punds plenty of times on 103 at 18 psi. i just only have access to 100 and 110 so i figured its better to go a lil overboard than to try and and use less than 103.

i second that, DO NOT take that motor over 14psi on a hack, it has no way of retarding timing or anything like that. I ran a hack and blew my motor on 10psi with good AFR's. I highly doubt the hack you have is even tuned, and if it is, its not tuned for high boost and you will be running extremely lean on high boost on a hack etc...... you will be fucked.

So in other words if you have to race keep what its at now as far as boost and use the best unleaded fuel you can. All parts are not design to be used with leaded fuel.

Re: (Sr420Det)
to original poster. if you are lucky enough to have it still be alive and running well, thats simply amazing.
dont push your luck. stop running it until its tuned. it'll go faster with a tune most likely too (wow)
your silly. stop being silly

run NTK sensors
to OP: good luck but best advice turn the boost down and save your motor while its not to late

Leaded fuel is good for your motor.. .the lead fills in the irregularities in the metals (cylinder walls, etc) and it acts as a lubercant on the hot side of the piston.
It does however destroy your typical o2 sensor. You can tune unleaded, but it will make the sensor fail much quicker. Make sure you tell your tuner your running leaded, alot will have a sensor aside for tuning leaded setups
That way one lasts longer for unleaded tunes, and the other, well, has it's life.

I did it before they had all the fancy EMS's of today, didnt have a choice, was the only thing available.

Re:
Ok so we have established that everyone thinks he needs real management and tuning... which I completely agree 200% but no reason to continue hammering on about it at this point since I am sure he gets the idea.
As for the octane... just dilute the 110 with premium if you want to bring it down a little bit. Honestly you should be fine running 110 for a few passes at the track though (this is just my opinion and I am nobody so take it how you will). In your situation the 110 would probably be better with all the timing your probably running from the hack. Although getting crazy with high octane when not needed is a waste of expensive fuel and can become counter-productive. As someone else said running leaded fuel will wear on some sensors a bit quickly but it does not pose any serious problems.
Basically put simply... if you fugger up your motor it wont be because of octane or leaded fuel.

no more like 6yrs ago, and the motor blew twice. Once a stock studded block and then a GE Sleeved Block.

so you blew a stock block.... then blew a GE sleeved block...
and 6 years ago, there was engine management.... no sympathy here....
and im sure those blown blocks didnt happen in the same year.... so why wouldnt you get some EM...
way to waste your money

Boost the expletive out of it! Blow it up! Then when you build your next engine you can take the time to learn about why it is important to have a good tune, no matter what fuel you are using. Silly Billy!

didnt ask for your sympathy, I like almost all others had no idea what they were doing boosting honda's 6 yrs ago, plus being 19 kind of has it limitations as far as money, so you say what you just said now without giving it much thought. BTW the OEM block lasted longer than the GE, had a boost spike on the GE block.

Re: (96 GSR-T)
heads up, but with the cash $70 for a home built WB02, a laptop, Crome free, freelog, and chips/burner, you can easily spend less than $200 (not including computer) and get a good customizable EMS solution... Worth looking into... it just takes patience, one step at a time.
