Is getting worn out
because idi turbos arent ment to make over 10-11 psi of boost, they super heat the air after that because they are not at all effecient in anyway
Correction. Low speed advance plunger. This cam and associated hardware adjusts your timing until such time that internal pump presure is sufficient to regulate your timing. This is why these engines are timed at 2000 RPM instead of idle. Reving up to 2000 RPM takes the linkage out of the equation. You probably don't want to mess with that. It's just going to mess up your calibration at lower speeds. But from the sound of it... oops. Too late.
Mel...do you think you can talk to your pump guy to see how much more fuel he can get out of it? Besides the injectors/injector lines...what can he get out of a pump...and still be streetable?
Just curious
No offense, but isn't that kind of an absurd request? Especially since whatever the answer is, your not interested in getting one? Let's say I come back with a number. 300CC? What would that mean to you then.

Bleeds IH red...
Yeah, read my post "rough idle and smoke" that shows what happens when that arm is out a little bit.....

I would be excited if that was the number!!!!!!!

Mel I totally agree with you on the absurd. I was simply wondering, just out of curiosity. Who knows maybe youR guy use to build DB2's for sled pulls and knows off the top of his head what they can flow. Wasn't trying to offend you Mel, sorry man.
I'm just curious, these threads spur that on

Hey Abull78. I agree about the body styles, I also have an 86 reg cab long bed, great truck!
Where in Nev are you at? I am in Vegas.

If the motor doesnt work out, I would recommend a 7.3L turbo block. It will be easier and cheaper to get parts like the lower compression pistons and it will have the updated rockers already. Also with the larger headbolts you will be able to get a better grip on the heads. But i hope the 6.9 works out.
He's in vegas too. I know it sucks when you find threads like this because there is so many post in such a short time its easy to miss stuff.
Hey Abull let me know when you wanna play with the timing I'll probly have time this week end.

A copper gasket wont work for us. The heating and cooling cycles will cause leaks. That will get ugly fast too. I prefer Felpro head gaskets.. Others like Victor Reinz. There are several good brands out there. Just wait for others to post what works for them... If we can generate enough interest maybe Cometic will make a few sets of there MLS gaskets but.... If they do I bet they will cost around $150.00 each... Thats really not too bad but if your on a budget that may take them off the table. One more thing to add... The block and the head surface will need to be finished to a better surface than what the stock gaskets require....

No offense taken. We are the only ones doing anything with the DB2. All his other high flow customers are working with 6 cylinder platforms and inline pumps. Oh, and $4 to $6K budgets.
