l67 wat to do?

[Beny]

Hey guys just got a 2nd hand low km l67 to put in my vs. The plan is to leave it out for six months whilst i build it up to be a super 6.Im thinking so far is heavily ported and polished heads with new valves ,springs ect. Water to air intercooler.yellaterra snout upgrade with 12psi pulley.And have the auto shift kitted and 2500 stall converter.and full dyno tune after

Just looking for peoples opinions and tips coz i may be doing something silly or unessary but not looking to go over the 5k mark on mods.

cheers

id spend a bit on the diff as well as. and the auto box will be taking a trashing especially with a stally
but yer there is a site called L67torque.com
justcomodores wont like me saying that but u might find a bit more info on that site.

You'll need a decent exhaust before you start and if you are going intercooled you'll be able to run at least 77mm/14psi even with the smallest intercooler and 67-64mm/17-19psi with a stage 2 intercooler.

Yea sorry thats wat i fogot to mention i already have a lsd in it with 3.45 gears atm and am going to have extractors going to my lukey 3inch cat bak. Does anyone know if ill get that much more outa the heads if i get em ported more arent the stock ones not to bad just wondering?

[VSIIBerlinaL67]

port the blower, u-bend, lower intake manifold. doing the heads will help. just depends how much you wanna spend.

[Beny]

yep only a 2nd yr so not going to spend heaps im thinking spending like 5k but yea cant see me sticking to budget. i see on ur page u done the conversion to how did u go getting it in did u do it ur self? or did u get it done how much did u spend on gettin it installed if u got it done pro coz im umm ing an arr ing bout it did u have any problems droping it in or was it straight fowards bolt in? hav u had ur car on a dyno? wat u getting at the wheels

[VSIIBerlinaL67]

i put it in all myself, with help from my old man, everything just plugs straight in. i havnt got my car tuned yet (im waiting for my rotors to be modifyed) but i'm expecting to have around 270rwkw

Still using the M90 and stock bottom end?

[Surfwagon]

Koo's only gets 250+rwkw with lots of special bits plus cam, heads and huge 3" tark twin exhaust so 270rwkw might just be a tad optimistic unless you are using a whiplle or M112.

Exactly what I was thinking. The M90 can only go so far...

im working with mace. and we've hollowed out the rotors on each lobe losing around 1kg or rotating mass per rotor. which will free up a shit load of power. still using the m90 with smallest pulley i can get which i think is a 57mm. ive also got stage4 heads and cam. ill just have to see once its all tuned i guess

That's the first time I've heard of someone doing that!!! Sounds good in theory. Goodluck with it, will be interesting to see how it goes!

ps. What cam are you running? Specs?

[VSIIBerlinaL67]

mace cam. the rotors are done they just need to be balanced and recoated

[Thomas1]

xpz cam. the rotors are done they just need to be balanced and recoated

Nice choice of cam. Great minds must think alike

Just cam it dude, the only way your going to improve the power decently is if you change the way the engine breathes, ie. a different cam profile.
doing the heads is all well and good, but alot of money can be wasted there without the need. just a simple tidy up and reco would be sweet.
the auto would seriously need attention, way more than just a shift kit. there will be decent torque having to go through the poor bastard and it wont like it in stock form and will definately start playing up.
with the stally you'd need to match it up with your torque, so you can't just say a 2500rpm stally. best way is to dyno the car, see where it starts to peak with the torque and take it back 500rpm or so for the stall point.

wtf are you waiting for man? wouldn't you be doing these ones ....
with it just sitting there.

[VSIIBerlinaL67]

ive been waiting for the rotors lol wanted to get it all tuned together. ive still been driving it though

[Beny]

I see i think the cam will go on my list got any sugestions like a stage 3?Oh man cant wait to rip my stock piece of shit out and put this new engine in just need the rest of the cash have yella terra snout on the way and stage 2 cooler.
