im installin a turbo on my friends hatchback this weekend he has a ls, its a drag kit, i was wonderin how do you retard the timing...and where would i get all my vacuum from? thx in advance!

 

what are you using for engine management?

please dont tell me you are using the fmu

fmu=poopy

Timing done either dizzy or via fuelmangment

I got my vac from the brake boost line on the firewall.

 

FMU for now
Tming done either dizzy? do you have any pictures of where u ran ur vac from

 

Vac should be taken from the intake manifold, not the brake booster. Taking the vac from the brake booster is dangerous. You can T off of any vaccuum source coming from the intake manifold. I suggest a vaccuum manifold to do it clean.

it is fine to tee off the brake booster. where do you think vacuum manifolds get their vacuum source from eh?

 

you dont want to retard the timing at all,

 

I t'd off from the fuel pressure regulator, that to my bov, and for my wg i used the fitting off my turbo....the fmu will get you by at low boost, but look into uberdata, and turboedit if your obdo for tuneing.

 

retard timing at the distributor a few degrees, or get an msd btm (but u can get other management for the same price). dont run too much boost without proper timing retard, hondas really dont like that.

run the wastegate from the brake booster BEFORE the check valve. the wastegate should be the only source off that vacuum line. bov and boost gauge can come off the fpr vacuum line

 

What year Ls motor are you installing the kit? Just to let you know uberdata or hondata is good resource to chipping your ecu. Honestly, I dont recommend getting vacuum from brake booster. Get it from intake manifold. uberdata or hondata could be used as fuel management. I am currently boosting with greddy TDO5 turbo and chipped ecu with uberdata.

 

Here is a pic of my setup if you look closely on the back of my intake manifold you can see where i tee'd off of the brake booster to my vacuum manifold. I have had it like this for a while and have seen no negative side effects and many people here run it that way.

 

get a vacuum manifold. looks a lot clean. as far as retarding the timing, you do that with a timing gun and turning of the dizzy. ditch the FMU and get better fuel management.
