Re: D1SC-3800-Build:Ground Up

1. Skip the Nitride chemical hardening of the crank, I have yet to see a crank fail at your power levels desired
2. Get a custom cam for your application, the xp or Nic cam are nice, but if you really want to make some power, get a cam made for your setup
3. Go with Comp OE lifters, the OER lifters are so stinking noisy, or go with ls7 lifters
4. Use stock coil packs, stock > any aftermarket ones

Re: D1SC-3800-Build:Ground Up

Don't touch the bottom end

Who is going to CNC the upper and lower intake? The way CNC machined parts work is someone ports them by hand and then measures them on the CNC and then creates the program to copy that work. Might as well just have them done by hand by someone who's good.

If you're going to 130#'s get a bigger cam. Matt M@ Stattama used to sell CSC specific cams for the 3800 iirc.

LS7 lifters instead of the comp ones.

Copper plugs instead of iridium.

Stock good condition coils are proven to over 900whp.

And like I said before, don't touch the bottom end.

Why don't you save your money and just buy a cartuning kit? Car will be faster and still be super cool, and you won't be building it for 2 years.

Also, the D1SC is WAAAAY too big for a 3800. P-1SC is what you'd want.

Re: D1SC-3800-Build:Ground Up

i think he got the d1sc for free from a friend, so that is why he wants to go d1sc instead of p1sc

Re: D1SC-3800-Build:Ground Up

Your going to need to mill or buy a milled oil pump cover plate to clear the larger double roller timing chain. You will also no longer be using the balance shaft in the top of the engine due to the new timing chain. You can remove it plugging the holes in the front and back of the block and save yourself about 5lbs. Since you are going to be boosting you will need to block off your pcv valve. I did this by installing a rubber cap with rtv on the top of the valve and threading a plug into the inlet passage in the throttle body. You will also need to put a breather on one of the valve covers. Some guys have gone as far as using an oil separator which is not a bad idea.

Do you have headers? Cause your gonna need them. Any plans for an intercooler, blow off valve or methanol injection? As far as tuning; are you going to get hp tuners and a wide band?

Re: D1SC-3800-Build:Ground Up

He going to have to lower the CR Meeperor, down from stock to L67,L32 specs, because of the amount of boost he is wanting (18+ psi). The L32 rods is what hell use.

I still would use a different piston, forged over hypereuetic.

Re: D1SC-3800-Build:Ground Up

the stock l36 bottom end has seen 9s. It can be done as long as the tuning is done properly.

This!!!!!

L36/26 bottoms can take 600whp no sweat!

If he's already going to be into the bottom end replacing pistons, main and rod bearings, you might as well use rods to lower compression as well. The bottom end of an L36 has done it, but anything north of 15 lbs of pressure with L36 compression is playing with fire. Personally, it's more wise and sound to play it safe and lower the compression. He'll still be able to achieve what he needs, and with a lower compression there is room to grow.

Not sure what reason there is to use stock compression other than being humorously cheap...

What are you basing that on? I have seen lots of L36's on 20psi. Hell most Turbo+Intercooled L36's here are on 16psi daily driven.

Stock compression makes the car overall more efficient, more power with less boost, better street drive-ability and better fuel economy.

For $2700 you could buy about 6 L26's, and I've seen a couple L26's handle the power that he's trying to make in cars that are utterly beat on!

Re: D1SC-3800-Build:Ground Up

thanks for all the Replies. Keep Them Coming.
Ill be updating the List based on all of your recommendations.

Sorry guys but i will be using the l-32 rods. HELL for under three grand. Which i think is dirt cheap. IM going with new pistons and rods.

ANY-one have any advice on what forged pistons i should go with that are provin to be strong?

**thedetailman** · 10-14-2010, 03:19 PM

Re: D1SC-3800-Build:Ground Up

SO with everyones advice.
WHO here thinks i can run 9.1 compression with 15 lbs of boost? or even ten. with the same horspower gains as of a motor with 8.1 with 15-20 lbs.

**thedetailman** · 10-14-2010, 03:36 PM

Re: D1SC-3800-Build:Ground Up

MOGOBS! lol. what type of plugs do you recommend? Someone has said copper ones.

but which kind? what brand>?

**caspernicus** · 10-14-2010, 03:38 PM

Re: D1SC-3800-Build:Ground Up

I wouldn't go any lower than 8.5:1.

Diamond and JE both make forged pistons for these motors. You can melt/chip forged
pistons too, but just not as easily. It's all in the tune. Everyone has an "oh ****"
moment. Sometimes people get lucky with stock pistons and nothing gets hurt, other
times they're not so lucky.

I run NGK 3346's.
