whats up

I would stick with pump gas, don't go to E-85 yet, plus isn't E-70 now? RETUNE!

You would need to upgrade the injectors again because the 680cc would get maxed out. You are set up with a good S-AFC and injectors. Leave the system alone for right now. Look at fixing your creep (but with those injectors you can let it creep up to 18-19 psi and be fine if it does), upgrading to a FMIC, Cams, ARP, list will go on.....

Plus if you are thinking about switching to a 6 bolt block, save the money for that.

I might have one available coming this spring, once I remove it from my car.

i have a 6 bolt block already i just want it cleaned up and then im going to re-use the 7 bolt cyl. head and shit but its gonna cost me 700 for the 6 bolt to be rebuilt and then 1800 or so to swap it at MAP

dont get me wrong, it runs good i just would like for it to idle at a higher rpm and it just wont do it for me

Have you tried the idle adjustment screw? There is that and the BISS. You should do a boost leak test too.

that screw is what i tried and at LSE they did a boost leak test for me.. but what is the BISS??

base idle set screw.

swap the engine yourself. save yourself the money. blageo23 has a ton of experience and wouldnt mind helping. you should check out his car in person...

Boost creep is caused by the wastegate not flowing enough. You will likely have to get the turbo ported and the O2 housing. 205 isn't too bad for low boost, get the issues figured out, then turn it up! Also, if you turn the boost up to 15 psi, it will still creep to 19, it won't make it creep higher.

Yes on needing wastegate work, incorrect on the ability to crank it up down low, here is why:

Most of the time it is an overall exhaust flow issue. The wastegate is getting choaked/can't bypass enough, so most of the time you have to start the boost lower than you'd like so you don't end up overshooting. Severe boost creep (like this car has) nearly makes the damm car nearly supercharged, increase in rpm is an increase of boost, and it says linear* when you are running into a flow restriction.


* It is not directly linear as you run out of compressor efficiency, but with his car it was shooting for 20+psi easily, something I didn't want to do on a smic w/o timing control on a 16g.

Welcome to the forums, glad you figured it out!

Then again maybe I am wrong, I only tune cars for a living and have set the boost on a 500+ of them by now... He was having a boost control issue, aka his wastegate wasn't flowing, aka he needed to address it with the ability to flow more air. If you give the compressor wheel a running start (aka more boost down low/allowing the wastegate to remain closed longer) why WOULDN'T it go higher? Again, Justin, I understand what you are saying, but his car was going higher on its own will, its a pretty common problem actually, something I get to deal with on 1/2 the dsms I work with. Unless we have a proper wastegate on it (or a good boost leak) the car will build 20+psi by redline easily, yes it will hold, but that overall boost spike will continue to rise until you run out of efficiency.
I really doubt we would tell a customer to keep the boost down for shits and giggles...

Thanks for volunteering me! But I would be glad to help if you got a place to work on it. And NOONE gets to check out my car in person until it runs!!! haha

Welcome again, darn winter now we will fight untill spring....
Here is a car that did the same thing, we did head studs and a AFPR and now its fine running that much boost.
