Default Buying all of the parts next weekend, help me choose.

Alright, so I am about to build a new short block since the shop that built my last three have all blown up. I am knocking again, and I think it is mostly due to them using cheap junk in my motor.

Enough about them, now for the new stuff. I have already bought a spare EJ257 short block, and also a 2010 nitrate coated crank. I am looking to go with ACL or Cosworth Bearings, ARP bolts, a set of Cometic Head Gaskets which I need some help with deciding on what thickness to go with.

As for the main parts, I have a couple choices I am looking at. I am considering going with a set of Cosworth Pistons with coated skirts and Cosworth Rods which I have found for about $1600. Another choice would be Carillo H-Beam Rods with CP Pistons which is also about $1600. The Cosworth set up would be a 9.2:1 compression ratio while the CP kit would be 9:1 compression.

I have a full complement of parts for the motor already. I am running Kelford 264 cams and have an upgraded valve train. I am sending my GT3582R turbo out to get HTA treatment. I have 950 cc injectors, Turbo XS fuel rails, twin Walbro 255 fuel pumps, and I am considering a Cosworth intake manifold. I made 624 HP on VP C16 on the set up before, but I am looking to do more when this is done.

I read about your experience at the previous shop on youtube, I'm sorry to hear that man.

The 2010 cranks need HX bearings in my experience. ARP Bolts, stock head gaskets. I'd say to choose a piston with lower compression if you're going to be beating on it on pump gas a lot.

Also, the Cosworth Piston/Cosworth Rod deal.. I believe CP makes Cosworth pistons and Carillo makes their rods, so take that as you will.

Tapout, my motor was built by that shop and is still running fine. They used Wiseco psistons,Element rods,ferrera valves,ACL bearings and ARP. If that is what you considered junk then I guess I will use junk to build my motors.I just got my Blackstone back (3,000 miles) and they said the motor was in excellent shape.

I too have blown 3 motors, the first was the Magnus motor Sleeved, Paulter rods and Ross pistons (didn't make it off the dyno).The second was a stock block with Weisco pistons and stock rods that I pushed to 630 whp,needless to say the stock rods did not like that and I was warned about that.The 3rd has oil pressure issues out of the gate and the builder made good on that.

I have learned that when things don't always go our way we find fault with everyone but ourselves.That being said I hope your new build lasts as long or longer as your last one did, which is if memory serves me well was a pretty long time for junk parts.

I really did not want to bring all of this up, but since it seems you know a little of 1/2 of the story, here is a little of the other half.

Mike, they did not use the same stuff in my motor as they did for yours. The kit they used in the motor in my car is the $750 Ebay special package that they sold to me as a built short block for $6000, so yes, I think for the money spent, the parts are not up to par. The manufacturer of these parts also does not recommend them for a 600 HP application. The Wiseco pistons and Eagle Rods kit used in my car... http://cgi.ebay.com/ebaymotors/Wisec...Q5fAccessories The ACL bearings and ARP bolts they used were fine as they are standard practice for most builders. What is not fine, and I have learned from doing my real research is that they charged me such an outrageous amount for such low end stuff. I do not blame them completely as I should have done more homework. In my defense, they really didn't give me the model numbers of the parts they were using for my build so I could check them out. Also, my fist build that I admit, did last a while, had CP Pistons and not the Wiseco. Also on the first build, I was not running near the final power number for quite some time. I think the motor only lasted about 2500 miles once they put the cams in my car and everything went to **** two days after the cam install because the pulley was not installed with a torque wrench, or so the story went. Since the day the cam failed, my car had engine problems. They told me they were going to take care of it, but then after they pushed me off for five months because they said they were too busy to look at my car, when I had paid over $20K through the shop, the motor blew up. They did not even look at my car for 3 months after I dropped it off, and then when they did look at it, they told me they were going to take care of it even though it was worse than they had initially thought. Two months after that, 5 months after dropping the car off, they told me that they wanted to charge me $4500 for rebuilding the motor and replacing the internals of my turbo which they screwed up when they left screws in the intake manifold of a motor they tried to put in my car but blew it up in less than a minute.

This last motor they put together did not even last 3000 miles on the waste gate only tune. The one before only lasted about 4000. They also had one motor they put in the car that did not last 30 seconds because they left screws in the intake manifold, and when those screws went through the motor and the turbo,

As nice as my car was a couple years ago, now it looks like a bunch of teenagers put it together with a bunch of leftover parts from a junkyard. Then, after leaving my car sitting outside for 6 months, every single piece under the hood either has a bunch of rust or corrosion. I also got my car back with a nice big dent on the door from a brick and stuff missing from inside. The paint was scratched up really bad on nearly every panel and the front bumper cover had cracks from where someone ran into a curb or something while test driving it. I picked my car up with over $7500 worth of damage. Look at the differences in the pictures of my car on page 6 of my cardomain site and then these which is page 7 http://www.cardomain.com/ride/247054...ield-va-us?p=7 Also, they did not even bolt down the FPR, which was dangling down by the transmission and they left the fuel rails to rub against the A/C lines which led to a nice hole in a $100 tube and a need for a complete recharge of refrigerant. I know some of these are minor, but they all add up. The pictures alone speak volumes about the work performed. I wish things were different, but they aren't and I am rebuilding another blown engine.

Any more tips on the parts? I will look into the HX bearings. I am leaning towards the Cosworth set just because the skirts are already coated. I was thinking the higher compression would help with the spool, and give me a little more low RPM power while driving around.
