turbo boost....

You're driving without your MAP sensor plugged in?

OK heres an
::update::

I did a leak test. My valve cover to the PVC valve was leaking to the catch can. I i tightened that up. But when i was taking that off i found something weird. Some greenish type of liquid. Anti-freeze i was thinking? Then i looked at my looked at dipstick no water no anti-freeze, Everything smells good too. So I'm thinking i might have a minor small crack in my head, but its not for sure yet. I'm going to give it some time and check it frequently. Tell my next oil change. As for the boost issue. Until i get my new injectors I'm going to only boost 5-6 psi. So i turned my mbc knob a 1/4th turn. this is all for now ...

I don't think you would really be able to see water or coolant on the dipstick. Drain some or all of your oil and then take a look at it. If it's a light, milky color, or if you can visibly see a water/oil emulsion, then you've got problems. You can also look at the coolant overflow reservoir and check for oil. I wouldn't necessarily jump to the conclusion that the head is cracked (although it is a possibility), but I'd certainly suspect the headgasket.

So i went to test drive again. No leaks i had to turn my mbc down a little to run 5 psi. So i rather run 5 psi then 7 that is going to make my engine lag. I Believe that its in the external waste-gate and the mbc that i can not boost more then 7. I have a spare head I'm thinking about rebuilding that because the port and polish i have probably isn't the greatest and made my head i have on now weaker. Any one have any idea's what i should throw on this new head? I have a spare intake Mani with injectors and fuel rail.

You should try to run straight vaccume to the wastegate. Take the MBC out of the equation for now. See what boost you get then. What are you going to use to control your new injectors? What size are they?

[newdsmtnr96]

right now stock injectors, Using a AFC, But no missing link sensor. i wanna get that and a sfmu before i try to boost more. But still psi is an issue. I found that there was a leak some where else too a very small one so i fixed that issue.

[newdsmtnr96]

Tial 38mm External Wastegate


Problem fixed i know the issue. I will be buying a better spring. Thanks every one who helped

Like everyone has told you ,you need a missing link or fcd. I had kinda the same prob and i had the missing link. My prob was still fuel. Get your new injectors and some sort of fcd/missing link and youll be fine. I just put slightly larger injectors in mine to hold me off till i got a sfmu. You are not sapose to boost more than 10-12 psi on an fmu though i think so dont go past that

Actually you not supposed to go over 6-8psi if you dont have a wideban, Now if you have a wideban you can turn it up til you run out of fuel im running 8psi spikeing to 10 wit no problems bu t every cars diffrent.

am running 3 psi cause the wastegate leaks.. got my new 44's and my new sfmu.. Now waiting for $$$$ for the fcd

I was hitting 6psi by redline with no wastegate actuator (basically wastegate wide open all the time).

Just some info to help educate. I see a lot of 420a guys ask what injectors someone is running and then start talking about fuel cut. Fuel cut is not a fuel thing it's a air thing. The engine in stock form or I shoudl say ECU and sensors in staock form have a air clamp. Meaning when it senses a certain amount of air or pressure it cuts fuel. Fuel cut is not a matter of not having enough fuel. If that were the case the car would just run lean and knock. I know you think yoru spring is your problem but it's not. Your manual boost controller even thought it's a cheapy is good enough to raise your boost double that of yoru spring in your wastegate. So unless you have like a 3psi spring your have another problem and like everyone said I'm betting on FCD or missing like so let us know when you get one what happens.

hey newdsmtnr96. did you get the FCD?

[newdsmtnr96]

yeah but it didn't work. We also tested in with multi-meter. tried to get it running the best we could. Didn't work, I'm going to try the missing link. I noticed that some people have bad experiences with the fcd and works good with the missing link. Then some have good experiences with the fcd and bad with the missing link. If this doesn't work, Gotta try something new.
