breaking my turbo virginity
Hello everyone..
Currently on the road to putting a kit together to get my car charged.. The car I have is a 1990 eunos roaster 1.6 and pretty much bog standard... Im based over in Cork in the south of ireland.. Im a virgin to turbo engines so ease it in slowly :noob: I've pretty mch spent a month researching and im reading corky bells book after seeing all the recommendations My list includes the following Garrett t25. Obtained Hoping to save up for an Artech main and down pipe Wb02 Braided lines IAT Knock sensor I have a n uprated clutch.. |
ill throw up a picture of the car as it stands tomorrow....
Oh and an mspnp2.. they look the tits |

Nice work Rhys!
Just curious which clutch you are using? |
Are you going to rebuild the engine? Why did you remove it?

farted around again for a bit last night. waiting on parts and then ill tear the engine from the donor car.. for now i did my gearbox seal
https://www.miataturbo.net/attachmen...ine=1335941196 and cleaned and painted the rocker cover.. https://www.miataturbo.net/attachmen...ine=1335941196 https://www.miataturbo.net/attachmen...ine=1335941196 Cannot wait to get working on the engine.. the turbo is just looking at me from the shelf :P |

did a bot more this weekend. the Ecu and manifold will be ordered at the end of the week :D Rang Joe Power in Dublin and had a chat about mapping.. . pics below of the hydraulic cam followers. most of them were pretty much solid so hopefully the clean will sort the ticking on warm up

Looks like a good parts list, only thing is I would go with a more proven clutch: ACT or FM in particular. Don't want to have to replace that sucker after all this work.
|
I agree with you completely.. I dont like the clutch really but it might have to do for a while.. I shouldnt have bothered getting it in the first place but ill have to see how funds are after i get my injectors.. Which is actually something i have no idea about.. Is it a case of the biggr the better or is there a fine balance there..
|
Another thing i never highlighted properly was the reason the old engine is being changed.. Apart from it being ridulously high mileage wise it was also a short nose crank version. The new one is a long nose
|
That clutch has been proven time and again by many people on this forum and many others too.
As for injectors, go big and never look back. |

With injectors the size is not the only specification that matters. Injector technology matters, and you want the newest tech.
https://www.miataturbo.net/attachmen...ine=1337888037 Miata/RX7 injectors are EV1 (1976 design, yo!) RX8/Deatschwerks are EV6 Injector Dynamics are EV14 If you only want to buy injectors once, go with Injector Dynamics ID1000. |

Cheers sixshooter small update from the weekend.. went at the bushes on the front of the car but got pissed off trying to undo all the bolts in the awkward areas.. so off with the frame https://www.miataturbo.net/attachmen...ine=1338161321 https://www.miataturbo.net/attachmen...ine=1338161321 https://www.miataturbo.net/attachmen...ine=1338161321 https://www.miataturbo.net/attachmen...ine=1338161321 did the crank seal.. was easier than i thought otd be https://www.miataturbo.net/attachmen...ine=1338161321 https://www.miataturbo.net/attachmen...ine=1338161321 https://www.miataturbo.net/attachmen...ine=1338161321 new spigot bearing https://www.miataturbo.net/attachmen...ine=1338161321 and dropped the sump so i could clean the oil pickup and drill and tap out the turbo oil return at work :D https://www.miataturbo.net/attachmen...ine=1338161321 |
found these on ebay.
http://go.redirectingat.com/?id=1125...%23post2106884 opinions? cant go wrong for £40 |
Not a bad deal at all! Keep up the good work. Did the crank seal take long to change? Would it be much more difficult to change it with the engine still in the car?

Got the engine and subframe back into the car last night..
https://www.miataturbo.net/attachmen...ine=1339053009 https://www.miataturbo.net/attachmen...ine=1339053009 next step is to rebuild the rear subframe... |
If you are doing the rear too it will be tight as new when you are finished.
|
the full car has new bushes including diff mounts and all new alignment bolts.. :)

for any man woman or child thats interested heres and update...all boost pipes are on and fitted, the iat sensor and bov are pretty much on, the MS is fitted and base map loaded (how do i double check this?) so im hoping the have it running tomorrow.. actuator and boost solenoid arent in the car yet but im gonna run the flapper open for a while.. get the feel of the tuning and make sure everything is working
https://www.miataturbo.net/attachmen...ine=1350683215 https://www.miataturbo.net/attachmen...ine=1350683215 https://www.miataturbo.net/attachmen...ine=1350683215 i just hope my next update doent have the word ''explosion'' in it |

after much messing with diff and so on i finally got the car onto its wheels again. ive wired the waste gate open for now so it wont build any boost as it isnt mapped. i might attempt to map it myself but i dont think ill be able to.. for now heres a small video of the exhaust.. i wasnt revving it much but you get the idea
https://www.miataturbo.net/attachmen...ine=1357914031 just click on the picture and itll link the video. ill get pics of the interior when i have it back together fully.. and then some more videos |
Nice looking ride. That exhaust looks great, keen for vids when its running.

I've been following this as well. Just because we don't have anything significant enough to offer a post doesn't mean we don't pay attention to your updates. I try not to clutter up people's build threads with empty posts.
We enjoy pictures of how others are doing their builds because everyone does things a little bit differently. I pick up better ideas to incorporate into my build quite often. |

We enjoy pictures of how others are doing their builds because everyone does things a little bit differently. I pick up better ideas to incorporate into my build quite often. i want to start tuning it soon.. my only problem is there is no one within 300 miles that knows how to tune mega squirt.. it just isn't the done thing in Ireland.. So i'm worried ill blow my engine up! I've read in the manuals that all you have to change is the Fuel and ignition tables? i want to start at 5psi to get the feel for it as thats as low as the waste gate is supposed to work at. i still havent bought injectors, im running the standard blue tops. are they adequate for 5psi? |
Start tuning with the wastegate arm disconnected so the flapper stays open initially. You will likely still see a couple of positive pounds at full throttle still.
Use the overboost protection feature of the MS to protect yourself from running out of fuel. Set it about a half psi above your intended max. If it starts cutting, back off the throttle a bit. You wouldn't want to spike to 6psi and blow it up due to going lean already. I don't think you'll have enough headroom to make but a couple of psi with stock 1.6 injectors. Watch the duty cycle while you are driving. If it isn't already on your main gauge screen, put it there. 85% duty is effectively wide open all the time and should not be exceeded. Above that you will go lean quickly because the MS cannot add any more fuel. Use the TunerStudio VE Analyze Live to autotune your fuel to your intended targets and get your unboosted cells functioning properly. Wait to tune the boosted cells after you get the normal ones dialed in. It will make life easier. And it will tell you if you are already in danger of running out of fuel when approaching boost. What base map are you using? Can you take a screen shot of your target afr map and your ignition map and post them here? |
Am i correct in thinking that the ve analyze is the add on for tuner studio? I still have to buy it.. Ill try what you say with the open flapper and see does it build boost. Im using the diyautotune base map that came with the ecu. I can post the tables tomorrow on my laptop when i get to work maybe you can point out where changes must be made.. (almost bed time here and im on my phone)
Cheers sixshooter |

Here are the tables sixshooter.. they are the tables i got with the basemap in the ecu.. i drove the car yesterday and noticed the AFR gauge never went lean. i have a video ill post it and i can do a data log tonight.

Wait! Your AFR target table is garbage! It doesn't even have positive manifold pressure (boost) targets (numbers above 101kpa)!
Yes, you need to buy the add on for TunerStudio to autotune fuel but it will only be as good as the target AFR table. I assume you must have been seeing some boost in the videos but I don't know how much. Do you know? I was seeing some high 12.x numbers in second and third gear and that might not be great depending upon how much pressure you were seeing. For the AFR targets you will need to change the scaling of the matrix by clicking on the grey boxes on the side and across the bottom one at a time and entering the new values. Then you can enter each of the targets manually as well. If the table I give you has less cells than yours (since mine is a lowly MS1), then add a line or column in between my values and interpolate the difference in between. https://www.miataturbo.net/attachmen...ine=1358179767 Are you using your laptop while driving to determine if your duty cycle under load is getting above 85%? How about using it to datalog an acceleration run in TunerStudio, then posting a screen capture of the important bits? |
The turbo spooling slightly will only cause a lean condition when it runs out of injector capacity (volume of fuel).
|
im going up to my shed now to drive it with my laptop. i can datalog and post the log here.
ill change the afr table and put on my boost protection before i drive again. I also have to refit my boost gauge as it isnt working.. ill have that working before i drive also. my table looks slightly different to yours but i see what you want me to do. itll post back in a few hours |
