3.8 to 4.1L, Questions

[Need4Camaro]

Would these Pistons be okay for a Forged 4.1L Turbo'd crank?

Would connecting rods be considered apart of the crank or would I need specefic forged rods aswell?

I beleive he said the rods would come with the kit but you should email him about it. the diomond racing pistons are great but i would spend a lot less money and find some used l67 pistons since they are 8.5:1 stock. if you are building an all out race motor then go with the diomonds otherwise save your money. What are you wanting out of your car?

compression doesn't afect bore x stroke ratio.

I thought the bore x stroke ratio equalled compression. I guess I was wrong?

With a lower compression ration, why would it be pointless to turbo a 4.1L? I'm lost... wouldn't more displacement set it off better? Why do turbo's require lower compression ratio's? </font>[/QUOTE]Bore X Stroke = Cubic inches I belive.

I want atleast 680 RWHP and I know I'm definately going to have to beef up the drive train. Oh yea, this is a dumb question but what kind of gas milage am I going to expect and will I have to use Premium?

First of all, the Stroked ZZP car is driven by Zoomer's GF, Vanessa. The stroker is a great option for those who have a higher mileage engine. Youll have a rebuilt engine with 0 miles and gain more power out of it. Im still undecided about what to do with my GP, but the stroker is still up there on my list of possibilites. Only ZZP has really shown what the stroker can do, and would be great to see nonsponored people running it and what times theyve gotten. I think you should do it. If you have the 4500 then go ahead and get the forged, but if not, 385 hp to snap the crank is a lot of power to be made NA. I say go for it and have fun while doing it.

you will have to run premium no two ways about it. you probably wont want to push your car that far if you want it to be a daily driver because dependability will probably go way down. Other than that your goal might be attainable but it still seems high to me. you will need to get all top of the line components for everything and i recomend having the block bored 30 over if this is indeed a race only block. you might want to get the diomond 8.0:1 pistons (which i think would be close to 8.4:1 with the stroker) instead of the 8.5:1 so you can run more boost too. you will also have to get a turbo cam to get that kind of power out of your car and you will probably want a custom grind to get the max output from your engine. I think something similar to the gt stage three cam from zzp but with less overlap, if that is possible, would be a good choice (cams are not my strong point). Upgrade all of your valvetrain components (look over at intense they have some good options). then as you said you will definately need a built tranny (if you want an auto the raptor-700 would be a good chioce). you should really start talking to zoomer about this, he is more than happy help and is quick to email back (not to mention he knows a lot more than me).

Whats zoomer's email address?

Also, just as an alternative, since I'm going to have to use premium gas anyway, would it be better if I just got a regular 350 or, LT1, LS1, or LS6 engine, mod it while it's out, (I've already spent WAY to much money on my car to just turn around and sell or trade it for a Z, thats why I'm going to mod it to be faster)

If I did this could I make a 427 Stroker without turbocharging get to 650 RWHP?

The Intense turbo car is the most powerfull series 2 3800. It is putting down around 550 fwhp i think. It is running a 10.1 in the quarter. I dont know what your plans for the car is, but for a 3800 to put out 650 rwhp, it will not be streetable.

I am planning a turbo system for mine and want around 350-400 rwhp eventually and 12s. I want to be able to drive this everyday on the street.

[T-Punk]

ok if thats the kind of power you are wanting it would be much cheaper to get an lt1, ls1 or lq4 and mod it out. you wont be able to keep control of that kind of power on the street very easily though so keep that in mind.

good catch

[Need4Camaro]

Maybee I should ask this then...

Whats the most streetable non-turbo power I could get with a 3.8 to 4.1L Stroker Kit? What Octane will I need? What kind of gas milage should I expect?

Whats the most streetable Turbo'd I could get with a 3.8 to 4.1L Forged Stroker Kit? What boost should I use? What Octane will I need? What kind of gas milage should I expect?

Whats the most reliable, streetable power I could get out of a LT1, LS1, LT4 with a Stroker Kit? What Octane will I need? What kind of gas milage should I expect?
