Thank you...

 

I still need an ignition switch.. the black carpet I got has been pressure washed and steam cleaned im excited to see it the pix looked awesome..
For ignition I'm running stock coils, wires, and 9's all around kahren recommended me to buy some new wires. I'm gonna do that prior to starting this thing. Eventually I'd like to upgrade coils to something stronger but I need to get the car running right first,
I might get some work in this morning before football well see how it goes..

 

I would like to hear from someone who doesn't sell this service.


How do the resurfaced housings wear? How long do you expect an engine with resurfaced housings to last?

Is the apex seal spring pressure irrelevant to producing good, consistent compression? Is my concern not valid?

Will stock 3 piece seals cause the housing coating to flake faster than the 2 piece seals?

I'd like to see what resurfaced housings look like after XX,xxx miles. I've only see pictures of resurfaced housings before the engine was assembled.

I'm not trying to start a flame war but I would to keep the discussion relevant to the thread's title. Goopy street motor build and R&D implies a discussion about resurfaced housings and how they perform over time.

JWteknix, you seem to be derailing your own thread...but I guess that's within your rights because it is your thread...but its annoying to read about the color of your carpet when you have such a specific thread title.

 

Judge Ito would be the one to ask, as he was one of the first to get a set of the goopy resurfaced housings in '07-ish and to my knowledge the motors he has used the housings with all still have higher than average compression, in daily driven cars that go to the track a few times a year.

i had my skepticisms as well, but after weighing it all out soon there will be no choice as i can almost clearly see mazda discontinuing our housings on the horizon as they have already done so with the 12A housings. until we have alternate ways of rebuilding the chrome surface or another type of coating that survives, this is the only second best alternative to spending $1200-1500 for new housings or using poorer sealing used housings. i have about 6 resurfaced sets out there so far and i haven't heard any bad news as of yet, the compression from turning the engines over simply on the stand after i assemble them, i get a much more positive restrictions with the resurfaced housings than with most used housings, meaning it feels more like a piston engine than a piston engine with the plugs out while turning it over by hand.

i started the service for that simple reason alone, cost of replacements housings has always been out of most people's reach and soon replacement will not be an option. most of the time these cars fall apart or are built for higher purposes than them lasting another 100-150k miles and/or 15 more years. they're weekend warriors, so expecting new mileage from a used engine is a bit of a stretch, but i can easily see most housings getting well over 50k more abused miles out of them. so i figured now is a better time to start then when mazdatrix lists "sold out" on their page, so 2-3 years from now when it does pop up there will be more conclusiveness to it.

the drawback is that the chrome will still flake off, but so far i haven't seen any real evidence that it flakes any faster than it would in an untouched scenario, if anything it seems less likely due to chatter lines causing the seals to dig in more and sharp edges on chrome peeling areas causing the seal to grab more and dig more. trying to be unbiased, the more i think about it, there really isn't much bad to be said about it at all. there are also softer seals on the market like atkins, which will cut down on wear to an extent, if that really is of concern.

but anyways, here is his words on the subject and JI has been around longer than most any of us. he is also a third party bystander who has no binding interest as far as i know aside from friendship with Jon.

but for any real conclusive evidence here, it will take us years to give more definite feedback. so until then Ito is one of the only people who can vouch for it. i too remember the days of pushing cermet coatings, which turned out to be a ball of **** so i have tried to steer away from this issue for a while but eventually we have to bite the bullet and be guinea pigs.

 

Prerequisite? I'm not sure what you meant.

You don't resurface housings which have been used with 3 piece apex seals or you don't recommend 3 piece apex seals with the resurfaced housings? Please elaborate.

Of course JI wants housing resurfacing to be an acceptable alternative to purchasing new housings. He builds engines for-profit and works in proximity to Goopy. He is definitely not an unbiased source of information. He has an obvious business relationship with Goopy and receives discounted services.

What you've suggested is that I basically should go to a car dealership and ask a salesman about the quality of their cars instead of searching for consumer reports.

I'm not trying to accuse anyone of lying or spinning the truth in their favor to benefit their business but I can't rule that out 100%. Please try to see this from a consumer's point of view. The person selling a product shouldn't be the one to evaluate it even though they're probably the most qualified and see the most results/data.

 

i said no to using 3 piece seals after rebuilding with resurfaced housings, not engines that ran them previously. i came to this conclusion because the clearance from rotor tip to the housing surface will be slightly larger of a gap, the rotors likely will be reused and the seal slots worn to a degree. with 3 piece seals once they wear the slot it will wear much more rapidly which is why most aftermarket seals are 2 piece, so that the seals won't wear the slot and fall out, resulting in a junk housing and rotor.

all you can do is wait for other people who have done it to respond, while not wanting to attempt it yourself. which as i said will take years for conclusive results. all while it does sound as though you're making out as if he is lying about his experiences with them, just to help sell their products and selling out his reputation. the choice is simple, reuse the housings and hope for the best, shell out $1200+ for new housings or attempt an alternative such as this, all of which are viable and people have done them all, i haven't had a single person ask me not to resurface the housings so far because they trust my judgement, not because i'm trying to make a quick buck.

 

I've done a lot of engines with the Goopy resurface process. One has upwards of 7k on it, a daily driven stock turbo car with premix/haltech etc. Still going strong.. Only time will tell however..

 

yep, so far i've noticed positive results with them but only time will tell if the now thinned surface will peel any faster than an untouched housing.

turning the engines over by hand they felt like they were sealing much better than most used engines with used housings after rebuilding, especially the higher mileage engines with marginal housings. anything over about 125k miles usually the housings are well below reusable.

2 engines i built with them are local, 1 still needs assembly, 2 were out of town and 1 is going into my GFs car. those are the only ones i have done so far in the past few months since i started doing it. the 2 local FDs started and idled right off the bat, usually i have to hold the idle for about 5-10 minutes before they settle down properly, this is because of higher initial compression.

often times even if the surface looked ok a straight edge told me a different story. almost all housings have a degree of uneven wear across the board. the oil injectors almost always cause more wear in the center area of the housings. another reason i despise the OMP system.

 

Now if I send you my housings to get re-surfaced (possible PP'd)

1. powdercoat before or after?
2. can you remove my exhaust sleeves, change of plans per-emptivley re-installed the turbo ones.

 

i would recommend powder coating afterwards but it really doesn't matter and swapping the exhaust sleeves is easy.

 

yeah but I'm no longer in school with full access to the machine shop, I have Joe hill billy garage now. Not nearly as effective.

 

meaning i can do it during the service.

 

well,
Finally a me day...
I got the carpet and dash back in my car.. looks great.
Now that all the heating assembly is removed its really easy to work on the vehicle.
I spent this morning running around between mazda and a few electrical stores, that couldnt help me find 2 gauge wire ring connectors...
At Mazda I got new stock ngk sparkplug wires for 30 bux w/ a new tail shaft seal for the trans it leaks real bad...
I order and few ring terminals off line
I sorted and routed almost all my wires after putting the dash in to make it easier and neater. I really like how much room I have now that my heatercore and blower motor are gone and I lost a little more weight.
Soo a couple more days(weeks lol) to wires everything up, Im also waiting on an ignition harness I got from t66 to replace my hacked up one, and another day to finish reassembling the interior..
So Ill probly be finished by the time it snows..

Please follow the forum rules:

14. Please include a descriptive subject for your thread. People shouldn't have to open the thread to find out what the topic is!

JWteknix- this isn't a general build thread. Stop writing about anything that's not the engine R&D or Goopy serviced housings. Carpet...don't care. Wiring under the dash....don't care!

15. Allowable sales of items must be done via our Classifieds section, and users must read and agree to the Classifieds Section Rules detailed in section 4 below.

fidelity101, Karack- pm each other, stop wasting my eyesight

 

umm dude, you aren't a moderator and there is always going to be talk in the open about services and products whether you like it or not. i pay to talk about services on this website, you pay nothing to get advice and read what other people are doing.

i'm not sure why you have your panties in such a wad about it.

on a side note, i am one of the largest contributors to helping people on this forum.. i don't think a few posts here and there trying to actually make a profit is going to kill you.

 

I have nothing better to do.

 

^
we can tell....lol

 

This is my build thread, like it or not stfu or gtfo..
I dont see you going in anyone elses thread and shitting on it..
If you could, please, explain how the wiring of my computer and other accessories is not vital, to my Goopy housings or engine R&D?
If I put new capet in my car. Good for me, it belongs in my thread.
Wheres your build? post it up...
hater

 

This is your build blog and the thread title is misleading.

Can you imagine how frustrated you would be if you used the search function to research a service or part and read through pages and pages of posts that in no way reflected the thread's title? You'd feel like you wasted your time.

Would it be acceptable for me to make a thread called "How to repair the AC system" then write about how to rebuild the engine? I don't think so...

This thread is a blog about your project car. That's fine but I think the thread title is misleading. At least post up some pictures of what you're accomplishing. Reading about how you went to the store to get some item is boring.

 

pics

 

set up new engine and battery grounds and got most of the dash assembled not shown in the pix

 

Did you pull the motor apart yet?

 

Its been a while, whats the word?

 

Motor was running great, started having electrical issues. Found the main harness and fuse block melted... The body of the car was beat up so I stripped and scrapped the rest.
Bought an 89 glx I'm in the process of swapping and upgrading it.
I'll eventually Create a proper titled build thread lol

 

Yeh start ur own thread...
