Lets Build a block!

[Turbo V6 Camaro]

yuou can do .600 lift with out piston issues, but you have to get head work for over .530 lift on the 3.8 motor.

[OneQuickV6]

Piston to valve clearance is more closely related to duration of your cam of choice than the lift. There are a ton of HIGH lift cams that don't have problems because of less duration, yet lower lift with high duration can have problems. Just an FYI.

for the short block, I'd wait and get the 4.1 stroker kit w/ some low compression pistons, between 8.0 and 8.5. take the entire rotating assembly, and balance it to 50%, remove the balance chaft, and have it all shot-peened and cryo'd. Also make sure the piston tops are thermal coated and the skirts are anti-friction coated. The thermal coating will keep the low-end cooler, and the anti-friction coating will reduce frictional power losses.

The Intense Stage 3 heads will be a great upgrade, but have 1 major drawback. U have to use leaded fuel additive to prevent the valve seats from being eaten away. read about it on Intense's website. I'd just get a good set of SSM heads w/ the combustion chambers enlarged and coated w/ thermal coating, as well as the valve faces. Stainless intake valves are good, and possibly using Inconel exhaust valves will reduce top-end heat soak from that valve since it sees so much heat. Based on head flow and blower type, match ur cam to that. if the heads flow well up high, have higher lift. if the blower is centrifugal, and the boost doesn't come on till higher rpm, then get a somewhat smaller lobe separation, 111-113.

get the lightest valvetrain parts possible for higher rpm use and less hp loss.

the leaded additive is a synthetic ..and is DOT approved...it's not real lead that is harmful to the environment.

Yeah the heads are being done now so no Stage 3. But those are nice. Do u think Super 6 makes good upper and lower Intake Manafolds?

[Turbo V6 Camaro]

ZZP is expose to have heads out for under 1000 soon its on there web site

[Gauvin007]

ok lets get this out of the way. The heads are done. I need to know more about the internals because i want to push some nice boost but i dont want to blow my engine

[Mogobs30th]

Depends on what you are trying to do, and how much boost you are looking for. If you want internals worth a ****, go with Intense. And if you are seriously going to use a good amount of boost, make the engine to L67 specs instead of L36. Go to www.intense-racing.com. Got any question, shoot me a PM.

[Turbo V6 Camaro]

i would go like i did for high boost basically what intense did only dont bye from them there to expensive

Diamond coated piston 8.5:1 c/r w/rings and wrist pins
Forged L32 2004 GTP Connecting Rods
ARP studs, bolts ect
Intense racing head gaskets
Comp Cams custom grind,
Comp cams Hydraulic Roller Lifters
Comp cams 130lb springs
Comp cams titanium retainers
Comp cams push rods
Cam install kit w/timing chain
Clevite 77® TriMetal™ Main Bearings
Clevite 77® TriMetal™ Rod Bearings
Clevite 77® TriMetal™ Cam Bearings
Lucas 42.5 pound/hour injectors (i may be going to 57 lb/hr)
Oil PSI kit to 80 PSI at WOT (get the from intense)
New oil pump

and not needed but every will tell you to get

MSD DIS 4
MSD Muti-Channle Boost Timing Control
MSD Custom Wires
MSD Blaster coils
MSD Coil Interface Modules

Gauges
A/F ratio
Boost
Fuel PSI

[Turbo V6 Camaro]

BTW i have PN#'s fo the MSD if you need them, it will cost about 1000-1400 just for the MSD things

[BadAzzRS]

L67 Pistons or Custom Forged Pistons/Rings
L32 Connecting Rods
Turbo Spec Cam
Ported Heads/Intake/Throttle Body
Bigger Valves
Roller Lifters
Stronger Pushrods
Stronger Valve Springs
Gaskets
Machined Crankshaft
Larger Fuel Injectors

That would be a very good rebuild, but if you want to go lightweight go with.

L67 Pistons
L32 Connecting Rods
Stronger Pushrods
Turbo Spec Cam
Stronger Valve Springs
Gaskets
Larger Fuel Injectors

That would be alot cheaper, but if your going to rebuild your engine you might as well do as much as you can.

I personally am probably going to buy a whole new longblock for 1700$

I could probably get 200$ for the pistons and connecting rods, 30$ for springs and retainers, $25 for connecting rods, $30 for lifters

So you figure $1500 for a new longblock, then id have to most likely get a new timming set 89$ New oil pump, new water pump, thermostat, spark plugs, wires, coils, motor mounts, new pulleys, new tensioner, new belt. so thats another 200-400 bucks. So the price gets up there, i figure if i build a strong bottom end, and do what is needed the most on the top end ill be fine and dandy. [img]smile.gif[/img]

[Turbo V6 Camaro]

if your runing hig boost 15+ PSI all the it i would get forgde pistons at least, i like the coadted ones but dont have to, coated would be good for high boost plus NOS shot

[Gauvin007]

i was thinking about getting the whole rebuild kit from Super Six. it has everything to rebuild your bottom end

[Arctc Wolf]

How insane do u wanna go w/ the motor? That's the main question that I shoulda asked u first, cuz some ppl feel that just adding a sc or turbo is good enough, and others wanna take it to the max.

For others who have mentioned it, why stick w/ stock displacement when the stroker kit will be out soon? More displacement will help make a lot more power out of a boosted motor. On average, with our motors, we gain about 1 hp per cubic inch gain on the top end. If this is true, then going ffrom 3.8, which is 231 cu. inches, to 4.1, 249 cu. inches, meaning a theoretical gain of 18 hp, on a NA car. boosted motors will of course make better use of this displacement, and along w/ heads and cam, this will help a lot.

Just to put this into perspective, a Mitsu EVO 8 got a 2.2 stroker kit(from 2.0 liters) put in it w/ just intake and exhaust mods, and gained 50 rwtq. yes, dohc 4v design helps that power output a lot, but that was on a motor 1/2 our size. Just think what our stroker kit could be capable of.

[Gauvin007]

Oh yeah man im looking at all the angles. Im still in the planning stages now. i want to put a good amount of boost from 8-10lbs. enough that would be able to really be a nice addition to the built motor. The SC will not be the power but just a adder to give me a nice boost
