OK this is on my personal truck, so I will only cut certain corners. I need opinons on exactly what parts I need. My truck is an 06 model. I have the engine out ready to tear down. The block is fine, just has minor blow-by. I have a paxton going back on the truck along with building a forged motor. I will try the smaller pully to get as much boost as the paxton will make. I am staying stock or close to stock ci. I would like to put a cam in to compliment the blower. I am running a paxton here, so the heads probably need to stay stock, correct? My performce parts are in my sig. I want BANG FOR THE BUCK! So I will spend extra if it is worth it, but otherwise I want to go the least expensive route. I will be calling Stinker, and prob getting everything through him, but I want everyones opinion here. The parts I will be needing in the next 2 weeks are:
1. Forged Pistons, which ones, what rings, what compression?
2. Forged Rods, unless my factory rods will support 800-1000HP.
3. Forged Crank, unless the factory crank will support the power.
4. Camshaft. I know its gay, but I want it lumpy as hell at the cost of a few hp. I doubt a cam costs power though, so which cam do I go with? Of course I want more power. Should I just call up Comp Cams and trust them to grind me a good one?
5. Clutch? What clutch do I go with? I have a Centerforce now that doesnt slip too bad, but is pretty sloppy with my old 640WHP. I want a GOOD tight jank when I drop the pedal/shift gears. JMB has the monster $1600 job?
6. Aluminum flywheel, or stay with factory?
7. Rocker arms, or stay with stock?
8. Mild head porting, or leave them alone right?
9. Larger injectors. I am ditching the paxton split second box. I have a VEC3, so I want to get bigger injectors, and tune it accordingly.
10. Tank fuel pump. Stock or get something stronger.
11. Throttle body. Stock or go bigger?
12. Intercooler. I am ditching the factory paxton water to air, & doing something like scrambler1 had built. I may even still buy his stuff if he wants to sell it. If not where do I get a bigass air-to-air intercooler.
*Question while I am at it. Scrambler and others have used much larger intake tubing with their paxtons from the blower to the intake. My thought is to try and keep the same size diameter plumbing between the blower and the intake. Thats the way paxton did it, is there really a reason to run larger intake tubes with the risk of lowering the boost? What do you guys think?
OK please you educated "been-there-done-that" guys, help me out. I just need opinions. Thanks in advance. Robert
1. JE, or wiseco, stay around oem compression or a couple points less in case you decide to change things later on, such as turbos, n/a, or procharger, or selling outright.
2.forged rods wil not support much, they are compressed powder rods, K1 makes really the easiest and simplest solution, plus are good for about 1200hp
3.the oem crank will support it, but i did find that mine after 7000 miles was bent 20 thousands, and i got three others that are also crooked, thats why we are going billet in eddies engine, we are having it done local.
4.camshaft needs to be a custom grind, and you can only get so much "bumpity bump' with a blower cam, you need a certain grind to work with blowers to control exhaust flow
5. I am selling spec, they have a full face stage three good for 950 ft lbs trq, but the mcleod is a killer way to go, upgrade with vipre hydraulics and your good to go.
6.stay with oem factory flywheel
7.harland, sharp,rocker arms will add hp, not sure how much , but will free up the valve train, on oem covers they have to be modified for them to work tho
8.have the heads ported, new valve springs, new valves, and hardened push rods. springs and push rods a must.
9.ditch the split second, stay with the vec its fine, go with 65lb or 75 lb injectors.
10.right now justins dual intank set up, or you can go to a custom big single, or a dual where one works and the other kicks in on boost.
11.Wait for cherry performance to finish the dual bore throttle body
12. go to a 1200hp intercooler, even a chiller for the intake temps.
stay with the normal size tubing the paxton only pushes so much air, dont make things too large
