$13.5 for the entire motor/turbo setup with the "new" turbos. Keep in mind though, this was using the BEST materials. Same power and results can be had for about $10k or less by just using regular materials.

whats your motor specs? also i assume you fabbed up the headers or did you use something?

Nitro, What does it cost to upgrade rods and pistons? Would a 32K mile shortblock need to be machined for new pistons or could I get some standard bore pistons? What does it cost to get upgraded rods, pistons and re-bearing the engine? I guess I would need to upgrade the oil pump, rocker arms, valve springs and injectors too.

maybe some et performance heads and a big cam can get you close to 500hp on a sd tune but it would have to be a 6 speed to be a daily driver or some automatic with a high stall ...and i doubt you would get a good fuel mileage lol...on forced induction im gettin 24mpg but if i get on it it sucks the living hell out the fuel tank lol through them skinny 60# mototron injectors hehe

for a forged block average pistons are arround 600 so are the rods
then you need arp bolts and blah blah
someone to tune it or tune it yourself

Hey guys, time is your friend. I picked up my complete motor for $2400 bucks.
-I looked long and hard and found a set of new Lunati Billet rods for $600!, I would buy your rods through Competition products, there race billet I-beam rods are among the best for about $750, GREAT deal!
Pistons are Wiseco 2618 25cc dished pistons. They can be had from Summit for about $525, again, this is the best deal on a piston you will find. Diamond, JE are total rip off's! I have been there done that.
Rings are regular Moly standard tension rings 1/16,1/16,3/16. When I built my motor last year knowbody made a 3.905 Hellfire ring yet, now they do. Buy the Hellfires. Otherwise, pick up a standard set for about $90. They are holding in my motor just fine with huge boost in a heavy ass car!
You will have to take the block in and have it bored to 3.905. You will need bearings for rod, mains, Those will be about $130 for both sets if I remember correct. Buy head and main studs at the tune of about $450 bucks. Use a stock 6.0 truck head gasket set for the 4" bore. Use stock cam and valvetrain. This setup with some small turbos will make about 800+ hp on pumpgas real easy. Mpg will not be affected. This covers the motor, obviously you will need some fuel system upgrades.
If you can weld, you will need about (12) 1.75" U-bends and a chop saw. You can build a set of headers with collectors for about $1000 or less. Before I weld high dollar on my turbos, I had $5500 into the entire twin system I have with using the BEST materials.

There is so much I can say and info I can give, I could go on forever. Hope this helps a little.

For valvesprings, go with a 918 spring and be done. Use the stock valvetrain for the rest, except the pushrods. Trickflow are a good pushrod and are far cheaper then the exact same high dollar stuff. Leave the oil pump stock.
Buy the 75lb injectors through R/C. Better to go to big on the injectors for a turbo motor in a street car. They do not affect driveability at all untill you get to the 96+ range with low IMP. Use a Aeromotive A1000 pump and regulator, they are good for well over 1000 hp and are dirt cheap.

Nitro, thats for the info. Your right I should just take my time and do it right. Im about to order $6000 in DSE parts to go ahead and get my suspension finished up first then I will get started on the turbo setup. I missed this turbo setup by $25.

http://cgi.ebay.com/ebaymotors/ws/eB...RK%3AMEWA%3AIT I had offered the guy $2400 for the setup and he never got back with me and 2 days later I got beat out by $25 because I was not there to bid. Oh well, im sure another good deal will show up sooner or later.

How much power do you want to make? Those are some huge turbos! Also, the A/R is WAY to big for an LS1 application. The R's have a water cooled CHRA and it has to be used or the turbos will destruct over time. The oild is restricted in those turbos to .030 feed. not enough flow to keep the cool. Way overkill, those are what I run and have'nt even started to tickle them yet at the 1000 hp level. Figure out your exact intended usage before choosing turbos. You need to get the right ones for what you want to do.
