Yup for sure... The group buy has not even started yet because people were not ready to go.

If we can ever get people together that are ready to go, this can move forward. I am set and ready to order whenever everyone else is.

^^^ Let it be known that he is not a member of this group buy, he ordered them on his own, not from me. So I have nothing to do with his missing ETA.

OK.

I think its time to try this again, because I am seriously ready to order my pistons. It will take until March for them to arrive, so if I want my engine ready for summer I need to get a move on!

So I have to do this now. Anyone who is IN, speak up by Monday. Then I will call and see if we have enough for any discount or not. It will take 7 sets to guarantee a discount... any less than that and I believe it is unlikely I can get the price down.

I'm in. Did you ever get news for the piston/rod combo?

I failed to follow through on that. I have been reluctant to call them again because I dont want to be the annoying guy that always calls to ask difficult questions but never purchases anything, lol. I definitely will be asking that on next contact, as I need rods myself.

It might just be you and me!

Guys please jump on this!!

Charles are these 4032 or 2618? I was planning on using Arias pistons but the ones I've seen are 2618 0% silicon content, they are stronger but they will expand more than high silicon content pistons. This means piston/wall clearance will have to be increased to compensate and I am not sure I want any piston slap on cold starts. Thoughts? Do you think 4032 forgings will support 700rwhp? What are these CP pistons rated at?

I would assume they were planning on 2618 when I spoke to them, since I said power goals were 800 to infinity. I will personally run either, it makes no difference to me.. so if you guys have a preference, that is the direction we can go.

I am sure a 4032 will have no problems with the power any of us are going to make. I mean... the factory pistons have shown to be pretty much A-OK at 575-600rwhp.

I dont know if they will quote a solid HP number for a pistons since that is a dangerous game, but I can at least inquire about their recommendation for this power range.

I will go out on a limb and make the assumption that they would allow me to mix and match in the order. I believe they start from a mostly universal forging and machine them down, so it probably makes little difference to them which they machine.. pricing may be different though.

Mine only took 6 weeks to get...

This group buy is officially closed!

It takes 7 sets to get anywhere with a discount, and I have been unable to get more than 1 or 2 solid commitments at any given time.

If anyone wishes to order a set of the pistons, feel free to PM me and I can order them with standard pricing.

Mods please close the thread.

Fawk.... Guess I won't be building a spare engine after all. Wasn't planning on doing the build right away but I would of bought the components for a good price... specially if we would've been able to bundle the rods with the piston...

Who were you going to have build the motor? The biggest thing holding me back is finding someone competent enough to build one locally.

Apart from the machining and coatings, I was going to assemble it myself. If you consider Ottawa local, I could inquire for a reputable engine builder in my area. If you're looking at Toronto, your guess is as good as mine lol.

I have no problem going to Ottawa for quality. The alternative was ship the car to the US, or have a short block build and shipped from the US.

Alright, I'll look into it. The gentlemen I deal with for most of my performance parts has been dealing with high end amateurs and pro racing drivers from Calibogie Motorsports and other racing venues for quite a while. I'm pretty sure he could point me in the right direction regarding which engine builder is more reputable/proven.

You're not in a hurry for this info are you? If not, I'll ask him next time I see him in a few weeks.

No hurry. At this point it might be next winters project, unless I smoke my motor before then.

I just knocked on wood for you.

Quick question,
I haven't really done much research into it but I'd figure I would ask since this thread is relevant.

My goal is also 800rwhp (so roughly 1000 at the crank) and I plan to use GT3071 .86 AR turbos. I haven't looked at the maps to see at what psi is most efficient for the turbos so I'm not yet sure what compression ratio would be ideal for E85.

Would 10:1 be the way to go?

If you're using E85 then yes 10 is "OK"

I went with 9.5 and couldn't be happier. didn't feel any low end power lose.

I just ordered my pistons.

2618 alloy, .020 over, 10:1 compression, compatible with HR and VHR heads. HD .250 wall 9310 steel pins. I went with no gas ports and no coatings, although the options are available.

CP does not offer a 4032 alloy piston for the VQ. They feel they are not worth it, as the 2618 is exceptionally stronger.

If anyone wants in, let me know. I have 2-3 days to let them know if the quantity is to be updated.

Without a handful of guys, we are looking at standard pricing... $1200 for the piston set with rings and pins. More if you want coatings ($25 per piston per coating) or gas ports ($16 per piston). The H Beam rods are $1725 a set. If I can get 7 sets of pistons or rods, price drops to $975 on pistons, and $1400 on rods. So that means if we had 4 guys buy pistons, and 3 guys buy rods, the discount kicks in. The pistons could get a little bit cheaper with lesser wrist pins, but I got the strongest/heaviest duty option pin they have.

I know I said the Group Buy is closed... well I guess I mean to say that its closing. We have a couple days to react, but I put my order in for my own engine and wont be revisiting the topic unless people speak up now, ready to mail a check. Pistons have to paid up front because they are custom. Rods can be paid for in 6 weeks when the pistons are done.

Count me in for the rods if we get enough people.

Pro H beam with 3/8 Carr bolts right? NI-VQ37HR>-65886S-06

Pro H Beams, cannot confirm the bolts at this time because he did not mention that there were 2 options. But I told him 8500-9000rpm and 800+ HP etc, I trust him to select the ideal option.

Ok. so between you and me we have a set of pistons and two sets of rods. 4 more sets of either pistons or rods and discount kicks in?

Precisely!

I would possibly be willing to purchase 1 additional set of pistons to keep in stock as I am sure as soon as the group buy was finished someone would show up looking for a set.

BTW pricing I quoted is with checks being made to me, and not including final shipping. PayPal/CC is an option if the buyer wants to take on the fees... but I figure this isnt exactly a RUSH item so mailing a check is a viable option for us.

That doesn't sound to hard to accomplish. We had decent list a couple of months ago...

1. phunk ; 100% in, any time before March.
2. Chuck33079
3. GaleForce
4. tibal
5. cosmogirl (already bought pistons)
6. OldBoy
7. djtodd
8. OMGWTFBBQ

guys?

Well, the pricing was much better back then too... it seems every time I call them, the price goes up $100

hahah better hurry up then. The price on rods themselves are worth it.

I'm going to have to eat the standard pricing sometime down the line. Dec/Jan is the worst time of the year for me as far as impulse buys go.

Like I said, I'm in for piston and rods.

phunk: pistons + rods
OldBoy: pistons + rods
Ron: rods

We need 2 more sets moving!!!

I know that feel bro...

Fellas

I have a few questions while I decide what brand to go with.

1) What CR are the GTM/Arias extreme series pistons?

2) What are the benefits of picking CP? If all of these pistons can tolerate 700+hp then what difference does the decision make in the grand scheme of things?

I really like that Phunk has stepped up to arrange a good deal for us- good work Phunk!

I am not sure about the Arias pistons that GTM carries. It never occurred to me to research their options!

In most scenarios, the vehicles performance or reliability will not demonstrate a superior piston between an Arias and a CP. My personal reason for choosing CP is based on experience and conversations with machine shops who see the results of built bottom ends more frequently than any performance shop. I find a general preference for CP to be rather common... but I also never hear that other brands would be considered a bad decision. I have engines running over 10 years on CP pistons now... while that doesnt exactly give me a hardcore brand loyalty or speak of any other brand, I prefer to stick with what I already know works.

The greater expense you may notice of these pistons comes into play due to the custom construction / specs. To use a "off the shelf" pistons from CP, makes their pricing much more competitive with other brands.

CP can also be trusted to properly design these custom pistons due to their experience with the VQ engine. They have all the data to compare between the difference versions of VQ motors and within a 45 minute phone call with them, we were able to come up with the specs for a 10:1 piston that is going to work with both HR and VHR heads with no drama. I can also trust that their heavy custom VQ piston experience means I will not have any trouble with misc drama such as oil squirter clearance etc... which I could mention my first set of Arias for a DE motor did not consider, requiring custom machining to the pistons... although I am sure that problem is long ago corrected (my experience was 10 years back)!

I have just had nothing but positive experiences with CP, and I have heard the same from many others. It sure would be nice if the piston manufacturers would catch up to the trends and start offering shelf pistons in the mid-range of compression ratios, especially for all the E85 builds... but until then, its a custom build price.

PM Sent ....

Last chance to get it in this!

This is it... I swear! LOL after Wednesday I am officially washing my hands of this group buy effort!

Charles, you should post something in the Forced Induction section. You'd probably get more attention there for the group buy. Just sayin'....

So... what you're saying is that if ONE person jumped in on this for a set of pistons and rods.. everyone would be saving about $250-300 for a set of pistons or rods?

You are probably right! I just dont feel right posting an ad in that section. I had it in my signature for a long time to see if people there would catch it, but it didnt appear to help!

From what I was told in my last conversation with CP... that was the case!

However, for all I know they already started on my pistons... once they start, it is too late. However I am going to assume that just like anything I do around here, it probably only takes them a few days to build the pistons, its just a matter of squeezing it in the schedule.

Good luck Charles. welcome to build block world!
