Intro turned hopefully epic build thread
 

Hey guys, Adam here. Been a member here since December when I got my first Miata, a 1992 C package with only 68,000 miles :fawk: My boss got me hooked on them after driving his for the first time. I already knew I wanted to turbo it before I bought it. I did a bunch of research on here got everything ordered that I needed. It was fun for about a week before I had all my turbo goodies in, and about another week to get everything installed in my garage, all without having to post any threads on here asking noob questions :noob:.

Pics of car when I first got it.

Ran great, stock clutch couldn't handle the power so I upgraded to a SuperMiata organic clutch

It worked great until I got bored at 10psi and turned it up to 15lbs. I wanted to test the limits of the stock 1.6 so I converted to E85 and ID1000s and also a FM stage 2 clutch since the SuperMiata clutch was starting to slip.

Oh yeah and I blew up the stock 1.6 VLSD at the dragstrip after multiple passes. I'm surprised it lasted this long, I sure beat the crap out of it. So I swapped in an open 1.8 diff and I got a Rx7 clutch type lsd and installed it at the same time along with Solid Delrin diff mounts.

Started getting spark blow out with that much boost and e85 so I got myself some LS truck coils and fabbed up this custom laser cut stainless bracket. And went sequential ignition at the same time.

At this point the car was pretty fast and seriously fun. I also competed in local autocross and many trips to the drag strip. Best pass at the 1000 foot track was 11.25 @ 100mph on street tire.
But of course this had to happen at some point since I know I was past the safe limit of the stock rods.

Don't hate to much. It was fun and a huge learning experience. It lasted for a good 6 months of beating the **** out of it. But now comes the good part...

Welcome.

Awesome intro, love the pictures and carnage.

Engine-popping success! ;)
When you get it running again, wrap that stainless braided oil line so that it doesn't wear a hole in the brake reservoir or the brake line.

Oh and heres a quick, crappy video (its only the first race) from a couple months ago racing my buddies boosted integra at the drag strip. This was before I went E85 and higher boost. It was a crappy run around 11.70 I believe.

^ what i was gonna say.

Cut some rubber tubing down the middle and slip it over, should do the trick.

Good build so far though. I'm shocked that little 1.6 took all that boost. Then again, the blue one i built is running around at 15lbs on a td04 (against my best judgment because it's on my tune). You should be able to get some decent internal parts for a 1.6.

Love it. Good quality work. Fun to be had with building up a new motor as well. Good luck with getting it back together again.

Yes at least I blew it up the right way lol. I will definitely wrap the oil feed line when I get it back together.
I will post more pics of all the new engine goodies later tonight.

Oh no, no more 1.6 :cool:

So I was lucky enough to get a free 1.8 engine from a 94 along with the transmission. Only problem was that it had been sitting for 10 years so you can imagine how much gunk and corrosion was built up from old fuel sitting in the engine. It was so bad on the head that it ate into the intake valves and valve seats. I figured it would be cheaper to be a used good head and rebuild it vs. getting the old one machined with new valve seats, etc.

Here is the engine before it was pulled.

Here you can see some of the nasty gunk and cylinder wall rust that had built up over the years.

Block is at the machine shop right now getting magafluxed, bored and honed.

I tore down the "new" used head and cleaned it really well. Cleaned all the HLA's, put in new valves and put it all back together. Much better

Painted valve cover, I like how it turned out.

Still waiting on a few more parts to come in and for the machine shop to finish up before I can start assembly on the new motor. Still undecided on turbo manifold and downpipe setup since I can't reuse the ones from the 1.6

I really hope you had the head machined

Cause it looks like you hit it with a wire wheel

Yes that was a pic before it was decked

Welcome to the site 92turbomiata, thanks for joining up!

Looks like a lot of fun, welcome.

Here's a hint though, when you click the IMG link on photobucket, it copies everything you need, just paste it into the post. Do NOT click the image button, then paste it. That's why you're getting the double [IMG] [/IMG] tags.

More goodies arrived

Supertech 11:1 pistons. I will be strictly on E85. Should be a good combo with boost. Hopefully I will have the engine put back together and back in the car in the next week or so. I'm really excited to see how she runs on the new setup compared to the old 1.6 setup

11:1 and boost? Really?

Damn.... that tune had better be spot on... lol
Im definitely looking forward to the results, no matter which way this goes. haha

Yes, if I were on pump gas I would have gone much lower but since I will be on e85 all the time I figured I would give it a shot. I know the tune we still need to be pretty spot on.

In for more catastrophic failure!

Ok what would you guys recommend for a built, boosted motor on e85? 9.5:1, 9:1, 8.6:1? I'm all ears since I don't want another catastrophic failure. I did some research on here and have seen people running 10.5:1 on e85 and I also talked to Bryan at Fab9 and he said I would be fine on 11:1 and e85 as that is what he is running in his miata.

If the tune is good and you run e85 all the time, AND you ensure it's good quality ethanol that is actually 85% ethanol, it should be alright.

I would trust what Bryan says more than all these haters posting in here
