Hey guys,
As we all know and read on here ZPI is trying to put together a production line for the xb and xa. Unfortunately, from what i've been hearing from ZPI there has been lack of interests. I'm calling everyone that owns an xa and xb in this community to step up. This thread is designed not to put down the idea of building a 1nz, or about any product they have in specifics. I'm making this thread to show ZPI what support there is from our community for a production line.

I'm also calling out ZPI on this one. I do realize you guys have been backed up with orders and pre-orders from the tC owners on scionlife and other sources, however i'm starting to get PM's and IM's daily from people asking me whats going on and product information that you guys have or will be releasing. I feel like some of these owners expressing concerns and seeking information would feel more comfortable hearing feedback and answers from you guys (zpi) directly rather than having passed down information through me. I hope you understand I'm not trying to add additional stress for you, however I do feel like if you guys could respond on this thread with answers regarding all of your products and future products...It may spark more interest that is currently lacking to buy your products.

Thank you, and please support this company otherwise I'm afraid they may have to discountinue their products for us due to lack of interests.

 

Bump.

 

I definately agree with killerx, make us the parts!!! I really would like to see what my car with a proper N\A setup can do. I have massive interest in the ZPI your pistons and port and polish head work. Please ZPI help us out!!!

 

i'm waiting repsonse from zpi on their head work. i really want to see a dyno to get an idea as to the kind of response the modified head generates.
The 24HP P&P failed: https://www.scionlife.com/forums/viewtopic.php?t=67782
So i'd like to see some proof to back up their claim of 15% gain.

The 11:1 pistons sound nice. Will be glad to get a set. with the pulley.

Maybe we could get a group buy going on the pulley and pistons? I can order those before I get my engine.

Get on their forum and ask questions!

 

I don't have an interest in a product that doesn't exist. If they can bring a kit to market that performs well and has soem reliability with good scientific backing to it (as far as testing goes) I may be inclined to purchase.

But really, how can we be excited and interested in things that are not available? Build the fastest turbo xB and you will have sales... *shrug*

 

Make us parts......nuff said

 

the thing is that they have some parts already. i just want more info on the head work. my decision about buying the pistons kind of depends on whether the head will help me with my NA scheme.

head, pistons (11:1 and 8(?):1) and a crank pulley lighter than the perrin.

apparently, people have not been buying the parts that they do have, which discourages them from making more.

 

Head, how much?

Pistons, They should release a F/I kit that requires them then... as of now, blitz/greedy guys aren't making enough power to need the forged internals.

Crank pulley, I'll buy it, but it's not HIGH priority right now. *shrug*

 

I agree with you, im trying going for the same thing. Im trying to get close or maybe even equal to the HP gain as if you were going F/I. There head job does seem kind of skeptical that alot of power by just port and polishing, but i guess we will just have to wait and see. But definately the pistons have to go with the head.

 

we want parts

 

plz make us parts

 

Yes, they already have out the following:
-8:5:1 pistons.
-11:1 pistons
-1.1lbs light weight crank pulley

They have a port and polished head package that they need someone to do a test fit for them before they start production of the head. Last time i talked to Kenny about f/i, they were hoping to have their first kit made by spring.

 

I think there would be a lot more interest in their parts if we could see what the results were from using them.

I think a lot more people would be inclined to order a set of the 8.5:1 pistons than the 11:1 pistons at this point. People ordering the 8.5:1 pistons will be running forced induction. And if they are running forced induction, chances are any issues with the ecu have already been addressed to some degree by either stand alone, or some sort of piggy back system. This is likely not the case for folks going the naturally aspirated route and eyeballing the 11:1 pistons.

Does anyone even know at this point how the ecu would react to the bump in compression? Has any dyno testing been invested to see what kind of gains we might be able to see providing the ecu doesn't completely negate the modification?

Then there are the heads. How can you build interest when there is a product that is only rumored to be a prototype at this point? How much more speculation can we throw into the mix? Get a working, tested, dynoed prototype up and working, and you will see interest soar. The same holds true for anything they are considering doing.

I think what everyone is looking for at this point is real world, streetable power packages. This appears to be the direction ZPI is wanting to go, but they are treading lightly. I understand why, but they also need to realize that it is hard to build a market for a product that doesn't exist. Especially in a market so many are skeptical about to begin with.

I think once ZPI can produce proven dyno gains with their products, and offer "power packages" they will see interest in their xB line of products increase exponentially. Until then I don't see much more than the few die-hard hopefuls we see on Scionlife every week making much of a commitment to the company.

Now that I have said my piece, let me throw my hat in the ring. Right now, the only xB in the family is my wife's. However, I am looking to dump my Prelude in favor of a 5 speed xB within the next few months. Once this happens, I will be watching intently to see what ZPI comes up with. I am definitely interested in ZPI products if and when they have done the research and introduce a market ready product.

And lastly, a question for ZPI...

Do you have any plans to address the stock xB/xA ECU? Obviously if you are planning on a turbo you will likely address this. But what about in your options for owners who want to stay naturally aspirated? Will you be the ones to finally "beat the system?"

 

^ The chances of the 1nz having issues with 11:1 compression is slim, stock is 10:5:1 so the compression increase isn't enough, or shouldn't be enough for there to cause any additional wear than what there would be to begin with. The ECU should be able to handle it just fine.

There are a good number of people wanting to continue n/a build up's on the 1nz if someone can show gains using the 11:1 and head package together. I really hope ZPI finds this thread because people need to see that ZPI can take care of us just as well as they do the tC crowd.

 

I'm definitely interested in an N/A build up at first, then proceed onto FI, based on dyno proven results.

 

I would agree that everyone want more power. If the cost is fair for the performance gains, I am in.

 

we want a swap.......

 

From what ive heard from ZPI, this should be a simple swapping of parts without any computer changes. The only difference i was told that you will be needing premium fuel and more spark due to the added heat from the higher compression ratio. They ar eincreasing the compression that much, i mean i dont think that are rods or crank should have a problem with a little more compression. The only thing i worry about is the heat.

 

Heat wouldn't be a huge issue. Just run full synthetic motor and tranny oil and you will be fine. The added heat wouldn't be significant enough to overwhelm all the moving parts.

As for the motor swap kit, just swap yourself. Everyone keeps asking for kits but no one has anything to show for it. If you want a swap that bad, buy the motor and trans you want, work with a shop and have mount mounts changed if needed and whatever else that will be needed in order to fit the new motor and trans (depending upon what motor you choose) and bam, you will be done.

 

I was up there on Thursday when I was selling a car to Kennys brother and got to see a little on what they had.

I do have to say that their pulley is very light and looks to be well designed. I didn't get to see one of the heads, but I do agree that if more people were interested then production would pick up and they would get produced.
