1st Consider the state of your engine kms and service history before you upgrade the pulley to a higher psi and rule of thumb on l67s is at 20 psi they just produce heat and that's no good 15psi would be the limit but that will depend on the state of your engine, t56 manual is a must if you do...

This How to will teach you how to disassemble a VE/WM Door Card Tool's Needed: 1 Stanley Knife, 2 Flat Head Screwdrivers 1 medium size 1 tiny size, 1 T20 Torx Key 1 Hot Glue Gun Step 1 Using the Stanley Knife Cut off the insulation on the back of the Door Card, it is only glued on there are...

funny how you both decide to reply back at silly hours in the morning when eyes are not up to fully reading and understanding what was written a suggestion and a example :(

Most of them, why? Just yank the plugs and pressurize the cylinder. No need for heads off. do i need to answer this really? how stupid would a mechanic be to do that and possibly drop a valve into the block when its far easier to take a ecotec head off for the repair then torque them back down...

omg your all blowing a suggestion out of the water if he gets lim gasket and stem seals for the exhaust might as well get head gaskets and get them from mace as there a high quality set used them my self a few times on ecotecs and l67's, and krusing i was just using your post as an example as i...

it was just a suggestion while at it with a rely good brand recommended by this site as he needs to do lim gaskets assuming he gets it done at a mechanics a mace vrs kit will sort the lims and seal the exhaust as mentioned here: and heads don't have to come off for that but a bugger of a job to...

well if you checked after a start then yer inlet manifolds while doing them you might as well do the head gaskets and valve stem seals full VRS kit with head bolts from mace are pretty cheap

how have you checked the oil? as the only other place that much water could go without being noticeable on ground is the inlet manifold, and if you are checking the dipstick before running the engine all you will see is oil as it floats on water once it sits in engine and separates start the car...

also you said it was left at the mechs for a few weeks while you moved house the hoses could have gotten brittle and when you started the engine could of cracked them your self as the engine dose shake side to side slightly as it kicks over

no it wont make it idle higher if they took it out and thrashed it they could have done something internal which you would hear ticks and knocks the idle would probably be ether a loose or broken air hose around the back of the charger forgot the names of them there small and go from the valley...

Hi Levi12345 its easy enough to swap a V6 ecotech done 3 on my old vx but if doing at a mechanics any engine will swap easy as you just unplug/un bolt everything then drop the engine and transmission on the k-frame, then reverse. but if you want to say change it from a v6 ecotech to a 5.7ltr...

i have a fabricator friend who dose small fabrications he told me what i roughly be up for and who i can talk to about having it made up for me, i have also gone over my designs and have the internal and external dimensions for the l98 inlet manifold and find that it will be better to produce...

Update #2: so after speaking with a fabricator there is 2 ways i can do it 1 whole pice or 2 pice the whole 1 pice will cost a bit more as the mold needed would take longer to do than in 2 pices at current aluminum price im not looking more than $2500 thats if the fabricator makes the mold up...

Update: i'll be speaking with a fabricator today going to go over the plans i drew to add length's and width's to my design's and find out a rough cost by the end of the day ill update again with my finding's.

cost wise should be always cheaper than a twin v8 supercharger/ twin turbo setup as the m90 to buy now are like 300 a charger compared to the v8 ones at secondhand price of 2500 upwards and the repair costs to said chargers wold be less as well

id think that once its set up with the twin turbo's i would run 2 intercoolers and 1 small one that should help dissipate the temperature at the block also the size of the inlet manifold that would need to be made to house the 2 l67's is a good opportunity to have a bonnet vent strait onto the...

so thats how i got my answer of no it wont wreck his diff

also from his other post 17inch vx ss rims with a spare stockie

Mullerman22 asked if 5mm difference would wreck his diff answer is no. And ok even if it was the old leaf style suspension my answer would still be no R_J_K as i have been told this before as i have had 18 inches on with a 17 inch spare and they dont do anything to the diff

now talking about tuning it and end goals are way off topic also (Quote: This is for the the purpose of getting a price to fabricate a duel into one for a l98 to see if it's fessable for me to do, For my plan is to put twin L67's both running 20psi plus twin turbo for a drag engine i'd like to...

no as vr/vs onward are independent rear suspension if one side sits lower because the Tyre is smaller that wont wreck your diff

i have watched drags plenty of times immortality but want something different and new haven't seen a twin l67 S/c LS series with Twin Turbo before

cam im not too sure of ATM am thinking a quite aggressive one, drag car? one day R_J_K_ ! yes i have a l98 Wm statesman but i also have a l98 with a bent rod picked it up cheap from a friend, so i nearly have enough saved for a full engine rebuild kit LSX have them at nearly $1600 then get the...

if the custom inlet manifold was made is it plausible remember the twin S/C is for low rpm once the twin turbo's kick in they will get negated im sure of, doing this because it id far cheaper to repair a m90 opposed to a tvs2650 for the l98 and they are far cheaper to replace and to find just a...

i intend to have a custom inlet manifold made for it read my first post and my first post on second page

anyway enough about losh's old 3.8ltr immortality and R_J_K_ what are you're thought's on my project?

but that could be fixed by ether using the us heads with it and fuel rail or port the inlet manifold and heads to be same

mhe though it would be what he needed as it dont look like a l67 inlet and says for buick 3.8ltr

Hey losh was looking for l98 supercharger inlet manifolds to draw and i think ive found what you need for the buick: https://www.ebay.com/itm/Dorman-Lower-Intake-Manifold-for-95-09-Chevy-Buick-Olds-Pontiac-3800-3-8L-V6/312542588934?epid=1124190162&hash=item48c4fd7006:g:rHEAAOSwzeldefRU

Above the middle vents in the dash nice and open there for ease of access

so i wouldn't know how the charger would react to that, where as the l98 v8 is like the l67 and l36 where it fills and fires each cylinder in its sequence

you just have to plumb it the way the buick is but i dont know how you would go about the injectors they are considerably different to the l67 as it was the l36 ecotecs needed to change heads as the injectors ran through the inlet manifold opposed to the l67 that had the injector holes in the...

1st pic is how ill extend the l67 inlet manifold to add the 4th port 2nd pic is how i want them set up on the block 3rd pic is inlet manifold top down view 4th pic is a side view of the inlet manifold 5th pic is the underside of a ls1/2/3/6 supercharged inlet manifold 6th pic is the best i could...

losh i am fitting it to a l98 v8 not the old buick v6

was thinking extend the front but the internals are going to be plumbed to suit the l98 heads ill quickly draw how i intend to plumb it

tyvm krusing

a pic of the underside and side would be good too as i cant seem to find them pics

i would like the underside of the inlet manifold measured the part that sits on top of the block just a length not width would be sufficient as i want to measure it compared to a l98 manifold and how much it would need to be lengthened to add the 4th rectangle port to be added to it

Hello JC Forumer's I am looking for pictures of L67 inlet manifolds for the purpose of drawing so far i have drawn a aus L67 charger, and the us charger as well i have drawn the aus L67 inlet manifold but now am up to the us one and when i search it in Google i only get pics of the one like aus...

and you will see the balancer and belt's wobble when engine is idling
