5 Attachment(s)
Hey every one so its been a few months since I started my engine build in school. decided it's time I FINALY put up a thread for the build feel free to leave any comments or opinions it's much apriciated as this will be met first major build I'm sure I'll be putting up questions. Just to give you a little info on the build its a 1.8 94-97 block and head running forged internals and once broken in will being working on turbo charging it.
I'll start with some pics from when I got it back in February and run you through progress so far https://www.miataturbo.net/attachmen...ine=1460083224 Bottom veiw https://www.miataturbo.net/attachmen...ine=1460083224 Dirty AF https://www.miataturbo.net/attachmen...ine=1460083224 https://www.miataturbo.net/attachmen...ine=1460083224 Initial removal and tagging https://www.miataturbo.net/attachmen...ine=1460083224 |

Primer/ painted the inside of the block after removing all the bad casting material at recomemdation from my teacher who is an NHRA dragster for improved oil flow back https://www.miataturbo.net/attachmen...ine=1460084081 Primer applied time for paint https://www.miataturbo.net/attachmen...ine=1460084081 Omg I'm in love ���� https://www.miataturbo.net/attachmen...ine=1460084081 https://www.miataturbo.net/attachmen...ine=1460084081 Now ready for assembly https://www.miataturbo.net/attachmen...ine=1460084081 https://www.miataturbo.net/attachmen...ine=1460084081 |

Nice pics.
|
Thank u
|
Looks like a great build so far. One note of concern from my point of view would be the paint on the inside of the block. I would be concerned that over time the paint may degrade and flake off causing debris to clog the oil pickup.
|
Wow this is looking good so far! Keep on keeping on man
|
The inner coat of paint was suggested to me by my teacher I had the same concerns my self but my teacher has been doing NHRA top fuel cars and building engines for 40 years so when he told me to do it I asked him y and he said it helps improve oil drain back flow and said he hadn't ever had any deterioration with time and he was pretty insistent about it so I figured I'd go for it I mean if 8000 hp engines can use it with no problem but idk I'll keep it posted over time if you want I'm curious too

This is an interesting watch: I think it is not worth the effort on a Miata engine, but why not while you are at it anyway? :) |
8,000 hp engines get rebuilt every 45,000 rpm. Yep. 10,000 rpm engine runs about 4.5 minutes, give or take. Fire, set idle, brunout, stage, race. Dead. Tear down.

Lmfao �� That sounds about right if not sooner hahaha ....but they don't repaint it every time basically I just had to make sure I cleaned the surface very thoroughly with brake cleaner so there was zero oil on it when it was painted

https://www.miataturbo.net/attachmen...ine=1462470790What's everyone think of color combo https://www.miataturbo.net/attachmen...ine=1462470790Fm throttle bracket thanks Keith and all the good guys in Colorado |
That's a lot of paint. Show us a picture after you've finished installing it.
...before all the touchup and oil smudges |
Ya that picture probably won't look nearly as good lol but I will for sure should be goin in about 2-3 weeks it should be running hopefully
hey I have a question for everyone though in regards to ignition timing my engine didn't come with a cam angle sensor and came disassembled so I was not able to put any marks on CAS now my only worry is that to adjust timing the engine is supposed to be running but how can I start it if it's not timed.....or is that just like a fine tune adjustment and and putting the CAS in the correct way gets you close enough to start the engine |

So, the timing is something I too am curious about. I have had a hard time finding any definitive way the timing process, installing timing belt, then getting the motor to start, then doing the actual timing after that. I will not be running the CAS so that is not really an option for me. If someone could link some info that would be great, I am sure its out there, but as I mentioned, I haven't had much luck finding it.
BTW OP, everything looks beautiful thus far, keep up the good work :) |

Kthnxbai ;) |
I won't have any ignition problems or worse detonation doing it like that will I ?
And does anyone else have any helpful tid bits to ad for the swap to make it easier. just FYI engine will be swapped in about 2 1/2 weeks is the hope as I'll be moving at the end of it the engine it self will be going in n/a just for the brake in and time it will take me to buy everything else and get it ready for the turbo. any comments or Questions greatly encouraged I'm still pretty new to this so all help is much appreciated |
I usually mark the CAS and head with a punch before I take it apart. If you didn't do that, putting it back in "about in the middle" should get you fired and then you can adjust after that. No worries about detonation at idle, it'll just kick and sputter if it's not right.
|
Alrighty thanks hornet that ones been troubling me for a while do you think I could mark the position it's in on 1.6 then transfer it to my 1.8 that's what I'll be doing if so
|
Well my car comes apart either Friday or Saturday for the swap I'll have roughly 3weeks to finish it and will be doing nothing but packing to to move and the swap for those three weeks. This will be my first engine swap on my own car I've helped friends with theirs before but this will be my first on my own car and I'm not gonna lie I'm getting pretty nurvious and starting to get cold feet

https://www.miataturbo.net/attachmen...ine=1463739448Engine and trans mated
https://www.miataturbo.net/attachmen...ine=1463739448Engine in the car https://www.miataturbo.net/attachmen...ine=1463739448Everything all bolted in just few odds and ends loving the exhaust wrap look https://www.miataturbo.net/attachmen...ine=1463739448ITS ALIVE runs great I'm super happy to say I have fixed almost all the minor problems I encountered (exeption being my coolant gauge is no longer reading on dash) and now it's running great and am super happy with the swap next step is finish break in then go turbo |
Your life looks a lot like mine for the next month. 1.8 build, swap into 90-93, move. No biggie right!?!?
Excellent work so far I shall say! |
Thank you petrolmed and yeah no Biggy hahahhaha ha little harder when it's moving to a different state but part one (the car) is done.
its running great though I'm real excited I wanna get the break in done so I can thrash it already lol but I know I'm pretty new to the Miata community and have kept my head down but I'm here now and here to stay so get used to me ;) |
I don't think you could put that air filter in a location any worse that that. Unless there is something i am missing, find that thing a cooler home.
|
^Yeah he has a point. Also, are you worried about paint rubbing off the cam gears and dirtying or affecting the timing belt and such?
|
Ya the intake location is horrible that was my reasoning for exhaust wrapping the headers I realize that's not exactly a fix for the problem but it's only temporary tell the turbo goes on I also might build a little heat shield and no havnt had any cam issues had to remove valve cover a few days ago to check on everything and if anything the belt is black in the gears but only barely it's been almost unnoticeable but I'll keep everything posted on this of anything
