gday all new to this site and need some advise, own a vy ecotec on 20's with clubby kit pacemakers genie 2 3/4 stainless and ss induction, in what order should i fit, rockers, cam, injectors, and the mighty yt topmount blower?
the exhaust was fitted at 2 3/4 to accomidate the blower
any advice would be greatly apreciated , cheers
Get the rockers first so you limit the wear on the guides and valve tips, and they can be fitted without a tune.
I would do the blower and consider an intercooler next, rather than changing camshaft.
Don't get it tuned intil the blower goes on and get an LS1 or LS2 MAF fitted when you do.
Injectors are part of the blower kit.
Once it's supercharged the best value mods will be doing whats needed to increase the boost, then do the cam, throttle body and heads last.
Cheers.

cheers mark, can these mods be done on a 7grand budget or would i be better off gettins a 5.7???
Not sure about fitting and tuning costs etc but the blower kit is $4950 and rockers $740
^^^ +1....
There is more potential in the 5.7 obviously...
7G on a ecotec will have you coming up on the top end of what you can do to it...
7G on a 5.7... you got a nice clean slate to start on and with a few mods you will have something thats fairly fun.
Just do the 6 dont listen to every1 who says go an 8 they just do want a v6 to beat them
If its what you want just do it
I WISH MY GRASS WAS EMO SO IT WOULD CUT ITSELF
When the L67 M90 reaches it's limit you can always fit a more efficient charger ot go turbo. There is only so much traction available so how far do you really want to go with a GEN# even though it's an awesome motor hands down. Petrol isn't getting any cheaper.
I'm sure its been said before, but if you wanna supercharge the ecotec, it'll end up much cheaper to swap her out for an L67. As a whole, it's built for boost and has much better potential for big numbers than trying to build up the eco. Do rings and bearings before you put it in and enjoy that for a while, then up the boost, add r/r's and intercooler, then if you wanna go even more nuts get some forged pistons, H beam rods, s/c cam, a few other internal goodies and chuck a whipple on top. With the right combination you can reportedly get 400kw at the engine. Who needs a v8 lol?
Hope this helps mate![]()
dont bother with a supercharger for the l36, get your self a l67 you will get the stronger motor and box and all the other things you need for less that the cost of the charger kit
