Im going to be running a DSM TDO4 and i was just wonder what i should use for management...

I was thinking i would use the AFC hack..with dsm 450cc injectors..if i do this can i use my stock regulator or will i have to get an adjustable regulator..


Sorry for the noobish question..im just confused (so much on my mind)

Thanks

Yes, you can use that with your stock fuel pressure regulator. Ask away. I'm good at answering noob questions.

Alright heres another one..

When rebuilding for turbo project i will need to to use a different gasket or spacer?... plus wouldn't i need different head bolts?..

Nah man your stock engine should be fine as long as it's in good shape to begin with. When you start pushing your block to the limit then you start having problems. I ran my stock d16z6 for about 7 months at 10 psi (about 215whp) and it has always held fine. I have recently did a compression test and I got 190 in all 4 cylinders.

A few weeks ago I turned the boost up though to 14 tappering to 12 psi (shitty internal wastegate) and I ended up slightly blowing my head gasket, so I just got a new OEM gasket and upgraded to ARP head studs. Seems to be running fine now and no more overflow tank problems or bubbles in my radiator. I think I might go do a compression test right now just for ***** and giggles.

Dr.Boost

Head gasket? No, unless your current gasket is blown, there is no real reason to replace it. Head studs are a good safety precation to prevent head gaskets from blowing, but not 100% necessary. I wouldn't worry about any of that unless you're planning on running some serious boost, or you're gasket is already fucked.

EDIT: Pat beat me to it. :P

Someone was telling me i would need to get a spacer to lower the compression before turboing...he seemed pretty certain but i thought i could just keep my gasket..

What's the compression of engine are you boosting? Unless it's like 10:1 or over you shouln't be too worried. Just make sure you have good fuel management and tuning.

My engine is 9.2:1 stock and it's fine for boost.

Dr.Boost

The stock gasket is fine. Some people like to lower the compression by using a thicker head gasket so they can run more boost with less chances of detonation, but you're not going to be running a scary amount of boost so you have nothing to worry about.

yeah a thicker gasket would lower the compression. Thats what I did and I'm running 8.0:1 and it ------- sucks. Stay with your stock compression

ya god help me, JE 8.1:1 comp pistons with a 2mm greddy head gasket.
