i have a 06 z with 65k miles. i does have the oil consumption issue. however the dealer said since its past the 60k factory warranty and my warranty i bought with the car wont cover it, ive decieded that im going to fix this issue. i plan on throwing a vortech kit on in this winter. my dilemma is, is it cost effective to......

1.rebuild the block? i.e. pistons,rods,bearings,gaskets,machine work.
2. buy a built short block.
3. buy a used short block out of a wrecked z

im aiming for 425whp and 375-400wtq.. i know the goals are high. but i think i can make them.

v2 blower with the 928 impeller and rebuild kit, along with the 3.12 or 2.87 pulley.. thanks for your input.

 

if you can afford the downtime then building the current motor is your cheapest option.

 

build it. sell the vortech and buy a TT kit or momentum single. thank me later.

 

If you are going to build the block, don't bother with the S/C.

 

If you are set on going SC, then picking up a used motor out of a wrecked Z will be your best and most cost effective option. SC is king for the stock motor. Mine is putting down 392/317 with just the 3.33 pulley and its a fun ride, but I also don't strive for big power numbers like some people.

If you are planning to build the motor or buy a built motor, then you'll get more power and torque from a single or twin turbo kit. You'll be able to max out the SC's limits easily with a built motor. You'll be able to hit your goal no problem with a Vortech and stock motor though.

 

i basically made those numbers u are seeking on stock block and 3.12 pulley no impellar upgrade or anything...bolt ons and 3.12 pulley and you will make over 400whp all day on a dynojet...

i will say if u are paying for everything weigh out ur cost of what you can find another motor vs. building for future plans...

 

Oil Consumption is not a problem as long as you keep an eye on it, letting the oil get low is the problem.
Unless you have the $ for a built block and TT i wouldnt touch the block.
Just do a Vortech on that block with a oil pan spacer, keep an eye on your oil and you'll be fine. You should be able to make those numbers on stock block without any problems.

 

He'll be tough pressed to get 375-400 tq out of a vortech. I was on 2.87 pulley with fully built engine, heads, and all supporting mods and barely got 370tq (but again this was a DD so maybe mine read low). Either way, about 18 grand in motor work to get about 400tq from a vortech. Not worth it when a packages turbo kit on a stock block can get 400tq easily.

 

ps: Not to highjack but I have a shortblock on my engine stand right now for a non-rev if you need a short block for a core charge. Core charges are usually 1500$ for a shop so I'll let this one go for cheap if you want to send it in and use it for a core charge for your built engine then you can strip and sell your oem block.

 

The reason for the sc instead of a tt is that it's my daily driver. I wasn't going to spend mOre mOney for the tt kit. I'd like to keep the stock block. I was just wanting to fix the oil issue and make sure it wouldn't b a issue with the sc. IPP has a built block for 2600$ I weighed that option. Time is no factor as I will be building it this fall/winter

 

2600 is a shortblock, you still need gaskets, oil pump, water pump, headgaskets, and headstuds. All that adds up to ~$1200 + assembly if you don't do it yourself.

 

Ya. Would a simple rebuild kit fix the oil issue? Or would a v3 blower b a better option.

I'm leaning towards just the sc and not touching the block now

 

A "simple rebuild" would fix it as long as that includes replacing the rings, but would still be costly and risk something not being put back together right.

V3 would keep you from starving your Vortech in the case that you let your oil get low. Im not sure if there are any disadvantages to the V3.

 

If your engine has a problem (oil consumption, likely fault is rings), I would recommend fixing the engine before boosting. We have competitive short block packages and are just down the road in KY. Please contact us before purchasing It sounds like you are going to be doing the work yourself, but if not we would be happy to handle the labor as well.

 

I have infamous 06 rev up oil issue. I was reading that doing a simple rebuild on the vq isn't worth it. Since it's a pita. so this makes me more confused.

If u build the block I'm going TT. But if I rebuild it's v2 or v3.
Would a "rebuild kit" b worth the money and time?


Btw, Jason with the insane g35 speaks highly of you guys. Did you fix his issues? I know your doing his block again right now.

 

If you are going to open the motor to replace rings, why not replace the pistons and rods while you are there so you don't have to worry about them as much?

 

I would probably pick up a good condition used block without any issues before I did a stock rebuild.

 

a "simple" rebuild would involve a full teardown, all gaskets extras. Like stated, it's pointless to do a tear down that far just to replace the rings (if the rings are even the problem, the problem might be with the cylinder walls).

Either way: rebuild or "build" you are going to have the expensive of tearing the motor all the way down and a few hundred $$ in cost of gaskets and materials.

 

like hal@dynosty stated, i wanna fix the oil issue before i boost it... i know the gaskets will add up... im looking to keep everything under 6k roughly

 

The issue was the built block I had was old and it was machined pretty loose

here is some engine ****







Im starting work on the car tomorrow, should be done in a few weeks
