My drop-in wisecos have cracks in their skirts, and they were never abused or assembled poorly. I measured everything, broke in the motor correctly and had shane tune it.

Still, cracks showed up. Googling shows i'm not alone with this issue.

If you're going wiseco, get the HDs. Otherwise get a better piston like Ross, CP, etc.

What are you trying to do with the car? Do you need low/mid range torque/spoolup?
All out power? Why are you building a motor?

A stock 2G head will usually beat a ported 1G head in powerband and peak power until you get into some big turbos. Porting a head, adding oversize valves, doing a 1g head vs a 2g will all hurt your spoolup and low/mid range power. Yes, a ported 1G head can beat a 2G, but unless you are trying to make 800+whp I would possibly go with a 2g head. Some of the big power guys like Kiggly run 2G heads, the 2G head is closer to the Evo head, which also have small ports. Big cfm numbers/big flow make power at very high rpms/very high power but will hurt power on a 16G.

Don't get the 1600s. Get FIC 1350s or FIC 2150s. The 1550s/1600s/1650s are junk.

The normal Wiseco's have well known cracking problems, unless they fixed that in the last couple years.

You don't want my vote on this one. injectors I would say 1450s and a single pump should be enough.

i got 40psi out of my 16g a few times 37psi was the normal spike. 272s would rock.

1g head vs. 2g head, if u have a 2g then do it if not I've been informed not really worth the trouble.

Figure I spend my lunch break answering a few of you folks haha.

Josh, bunch of questions, a lot of which have been answered haha.
What are your tuning options?
Going to be using DSMlink v3
Are you using a 1g head or a 2g head?
Was stated, the original plan was a 1g head...debating that now
How high are you reving?
No more than 8000
What intake/exhaust manifolds are you using?
Stock 1g intake manifold, fp race manifold.
Do you plan on keeping the 16g forever? Evo 16g?
Nope, just for the rest of the summer, then hopefully buy an fp30xx during the winter downtime.
How long is "for now"?
^^^answered above
Why an external gate?
Cause the 16g I have is setup for it already, the wastegate hole has been welded shut. Plus less to buy when it's time to switch to the bigger turbo.
What boost levels are you trying to run?
Pretty much maxxing out the 16g, so 26-28psi, 30psi max.
How much "bigger" do you plan on going?
Ideally, an fp3052 or 3065
What are your overall power goals?
Reliable 400hp, maybe upwards of 500 when the turbo is upgraded
DSMlink is a good system, which version?
V3
Do you have a wideband?
One of the first things on the list to buy
Will you be doing any tuning or having a professional do it?
Professional, tuning is something thats new to me, and completely foreign.

I like the HD Wiseco's, but man it is serious overkill for your setup. I don't really know about the Manley pistons but they seem affordable and may be worth looking into. ExtremePSI shows them in both 8.5 and 9.0 ratios. I personally would go with 8.5 because I feel it will only assist in making tuning simpler, and well if you want more power, just add more boost!

Is there something wrong with the motor, because really it seems like the money spent building the bottom end could be wisely spent elsewhere since you're going to be on a 16g setup.

Everyone will have their own opinions, and it's your choice in the end to decide what is best for you. Good luck with the build!!!
I would ideally like to overbuild the motor, so that it can handle whatever needs to be thrown at it. The current motor is blown, so its time for a new one. 16g setup may only be for a month or so, so that's why I'm building up.

But running a 16G means you can't really run much boost on top end; 30 at most even with all the tweaks and 'tricks'. I would go 9:1 if you want to save a little money, otherwise 10:1 custom pistons. He's going to run E85, so it can handle it fine.

I do agree on running the 2G head.

I think the BC272 cams are the perfect match for a 16G, no big loss of off-boost power, same spool as stock cams, more power and torque everywhere. They seem to make the most of the 16G, bigger cams will just trade off torque and spool for maybe a few more unnoticed hp. It doesn't pay to lose a bunch of torque with a turbo that's basically known for torque and mid range power. The torque hit is what makes the 16G so fun; I regret getting bigger cams for my car.

Save the extra expense and parts of an external gate and just get a higher pressure WGA, such as a Holset one, so you can hold a few more PSI on the top end. Ebay downpipe and exhaust, or just no exhaust at all :)
That's why I wanted to do a 9:1, get that little extra compression, and still be able to go a bit bigger. I want to get everything I can out of the 16g, which would be the reasoning for higher comp.
I will look into BC272's, a friend of mine uses them, and likes them.
Turbo is setup for a EWG, and I already have the exhaust.

What is your REAL goal for this car? Mightas well do it all at once. With all that, mightas well just do a 6765 setup on a built bottom end w/ a stock head/mildly modded head. Call it good and just go from there. Anyone who knows me though knows I think the steps between that are meh.
Summer DD, street/strip car. I don't want to do anything that big, that sounds like too deep of a money pit for me.

Wiseco makes a shelf stock piston in 9:1, and we've built many motors with standard Wiseco's without a known failure. Standard Wiseco / Eagle will be more than enough for your goals, you would be wasting money on HD's in my opinion, but what do I know ;)
Thanks for the info boss, but I have seen A LOT of wiseco issues this past year. The HD's would be an extra precaution.

A fun DD summer car, that I can take to the track and have fun with too. I enjoy the low/mid ranged spoolup on the street, which is why I don't want anything too huge for a turbo. Building a motor to help me sleep at night. I understand stock dsm motors can take a beating, but that extra reassurance (paired with a good tune), would make me feel better about my setup.
I will definatley look into using a 2g head. And as for injectors, I have a set of 1600's, maybe I should start looking for new, less huge injectors.

Thanks, Aaron. And 40psi?!?! Jesus...haha. 272's of some kind will be my choice in the end.

Sounds like you have a decent plan then.

So in the end I'd just make sure you spend the money wisely, which planning ahead like you are doing now will help with.

HD's are great pistons, and are definately "overbuilt" for you as you stated you wanted anyway. But money could be saved by going with those manley's (again I have no experience with them) or other cheaper proven pistons like were menioned (Ross, Mahle, etc). But like I and others said, I'd personaly opt against the standard Wiseco's.

Eagle rods are going to be more then fine for your goals.

272 cams. Im still a fan of the very much proven HKS's. Find a set of good condition used ones and they should be decently priced, and you'll be good for years to come. If you do plan to rev semi high, you may want to consider some better springs just to "help you sleep" as you put it. Stock springs aren't aweful, but if we're talking about a head with 120k miles, those stock springs may not be like new anymore. Some cheap crower springs would be affordable, and would again work for plenty of years to come, as long as you don't go to some more extreme cam setup.

I think you're going to end up with a pretty strong platform that you'll be able to build upon in the future and will withstand a lot of abuse.

One thing not mentioned, that is becomming more important to me, is ensuring you get a good seal on your head/block. Consider L19's and a decent headgasket. Once you go to a larger turbo setup and higher boost levels, you start to run into head lifting issues. If you get a nice good seal from the get go with strong fastners and a good HG, then you hopefully won't have to worry about that ever.

Those injectors will be rough to tune at idle, too big, especially for a 2.0L. Don't regrind the cams, just pick up a good set of used HKS 272's for a couple of dollars more.

AH yes, the headgasket/headstud combo. I will be adressing that issue as well. Wouldn't spend all that time and money, just to toss a crap headgasket on there haha. Most likely will be using a set of MAP heavy duty headstuds, paired with a permatorque or maybe just an MLS (seeing as the head and block will be resurfaced).

Hmm, well I may have to look into other injectors then. Seems that there is a consensus that 1600's aren't the way to go. I had comtemplated just getting a set of delta regrinds, as people have been seeing some good results with them. When the time comes, I will be looking for a set of used hks cams, as I did like the 264's I had in my car.

Once again, thanks everyone for the input, really appreciate it!

The only issue that 1600s have is the cruise miss. Idle is no problem I got them to idle with BC280s perfectly.
