Sam's 1.6 MX-3- LT Turbo project.

[youdirtyfox]

Cheers! bit by bit yes just bought some M14x1.5 banjo bolts with a 10mm hose connection to try for the water lines on the turbo
Still to buy:

Clutch.
downpipe flange.
Oil lines.
injectors.
lambda boss.
few more silicon joiners now the turbo has changed.
lots of various hose clips.

Still to do:
fit clutch.
clock the turbo.
sort water unions on turbo
modify oil drain outlet on turbo.
make downpipe.> not my favourite job, currently looking into a chop saw/hard disk cutter arbour for stainless! either that or its going to a hacksaw job:(
swage/bead alu intercooler pipes.
I/C mounting bracket + weld outlet/inlet back on.
IACV spigot on boost hose.
recirc spigot on air pipe

Thanks! I had a friend help me out, we probably spent 5 hours doing research, then another five hours wiring it in.

There is no tune right now, all the fuel, ignition tables are set to 0. So its just there running but not affecting anything.
We are either going to street tune it when boosted or take it to be mapped on a rolling road unless I can find a map for a miata
that might work on the AEM/miataturbo.net forum.

nice work. Use the data logs to help out with the tune. It can be a bit of a pain, but it will at least get you rolling.

[youdirtyfox]

cheers mate, the data logger is the bit we didn't understand really, what does it do and what's it triggered from?

[youdirtyfox]

Been busy lately configuring & clocking the turbo so the compressor housing points more towards the intercooler. It does spin without taking the circlip off just needed a few tap with a rubber mallet to get it going. This does now mean a new wastegate actuator though which is on order from the states, went for a 10psi unit with an adjustable arm to be able to set the spring pretension and a custom bracket.



Have also bought 2 x M14x1.5mm banjo bolts with a 10mm hose tail to use for the water, but I also managed to redrill the VJ water connection pipes from 12 to 14mm so I can use them if needed too. Oil drain I did modify then realised it was the wrong size hose connection so an oil drain kit with a 45 degree 12mm hose tail is on order along with 1/2 meter of stainless steel overbraided hose to connect to the sump and a 57mm-64mm silicon reducer for the air intake. also got an issue with the compressor flange to overcome as the pipe that came off the 200sx points in the wrong direction
so that will need a flange buying for or the existing on being used but with a more favourable direction on it.

Will edit pics into this post as things start arriving

Compressor flange issue sorted! cut off both ends of the elbow and machined them flat again ready for welding.


Rear of Turbo water connection, 90 deg. bend to hopefully miss actuator arm.


reducers good.

Good progress, cant wait to see you up and running with some boost.

[RS_OBD'oh_2]

you have little work to do now. But you did things in a better order than I did. Save some data logs with the stock injectors (print them if you can). This will give you a great idea of what AFRs the ecu is trying to pull / load/ rmp. Go slow, try to keep it at what ever rpm for a few secs, instead of driving normally. Trust me, you'll figure it out, you seem smart enough and did things I wish I would have. Always stay on the rich side when you start hitting the boost. If you start to see some higher numbers on your afr or any boost creep... back off. Often, the hardest part is lifting.

TBH, funds have gotten a little tight and I never did my pro tune. She drives good and is a hell of a ride... but runs as rich as Jay-z at a house party. Use the AEM forums, they pointed me in the right direction.

[youdirtyfox]

ECU was the main thing I want to get sorted and working, the rest now is just a bit more fab. and nuts and bolts! Then the tune..
Ok thanks sure will sort something out will hit up the forums when needed.

With warnings of a few car break ins round my area I wanted to get the AEM tucked out the way incase it was mistaken for amp.
managed to squeeze it in behind the stock ecu and stuck it to the floor with heavy duty velcro, comms lead routed up to the back of the glovebox also.
Will put the side panel covers back on as soon as I have found the fixings again, as there are also some new MOT laws in force now I think concerning ecu tampering?!

[youdirtyfox]

Designed the intercooler bracket monday and made it today,
it will bolt to the upright holding the bonnet realease catch with plenty of rubber grommets/washers so its got some movement as not to stress the end tanks.

Im thinking body pins to attach the bracket to the 'cooler?!

38mm - 51mm silicone 45 degree elbow bought for intercooler to cold pipe.

Nice progress! Cant wait to see some running
Videos!

Feel like we need some new pics of slammage

[youdirtyfox]

Thanks, yeah i'm alot further along then I was before,lol

Tbh I have been too busy with the build for photoshoots, I have found THE perfect spot for some new ones though! although there is a big steep incline to get too it, so I'll have to get prepped one day to see if I can make it down there:D

Here is an old one though that I have been playing around with in PS!
Next lot I would like to take I would have my new wheels on before though

[Josh]

Nice Sam, Looks so good. I wish I could go this low. but I would not be able to get in and out of my condo building It looks FU@#IN beautiful!

[youdirtyfox]

Thanks Man if it didn't look so good I would think about raising it a little, but just cant bring myself to do it though.
16's will give me a little more ground clearence I guess.

On a slightly different note had my insurance renewal through this morning and its actually gone down! as some of my speeding points have come off (after five years!) This is all good when it comes to the extra they are going to charge for the turbo.

really? you have to report the turbo to them? I have never said anything about my swaps to my insurance. They told me that as long as I have pictures and receipts of parts installed then I will get it payed back if anything happens.

[youdirtyfox]

Yeah you have to report all mods. otherwise your insurance is void in the event of an accident. luckily I'm with a specialist insurer who doesnt take cosmetic mods into account ( or charge extra) but power increases will cost more, I think when I asked it will be another 250 pounds (GBP) a year with the turbo quoting an extra 40% power increase. Thats why if I wait till next year when my other set of points come off it will make it pretty reasonable with the power increase. At the moment I pay 420 pounds a year fully comprehensive.

[Josh]

Well that is not so bad then. every time i look at your car I want to lower mine.. Every time!
