How to Turbocharge your NA for 2k, build with TONNES of pics and info.
Gday,
So I opened my mouth on the Aus forum and said I would turbo someones NA for 2k, just so they didnt buy ITBs.
So here we are.
This is for everyone who is wondering, and all of the blokes who swear black and blue its impossible.
This is for everyone who says you cannot do it 'right' for under 5000 etc etc :mrgreen:
In this thread I will go through all the steps to build a basic, Greddy style system, done properly, with no corners cut for a big improvement in power and much more torque. It will be updated as the progress happens.
This car is 100% stock except a 2" exhaust and intake, the only part that will remain is the catback, this setup would work on a stock exhaust, but we have the 2" so we will use it.
It will use a Log manifold for reliability, spool, its small size and price. It will use a Garrett T02, which owes me about 80 dollars, and has a brand new never used CHRA (Centre housing, rotating assembly) so its vital moving parts are brand spankers. A used T25 or t28 or TD04 from a wrx could be used, all of these are available used for a couple of hundred dollars in good nick from ebay and the forums.
It will use good quality oil feed and return, and a 2.5" downpipe that will bolt to a stock exhaust, although this car has a 2" straight through SS system already. It will not have an intercooler or blow off valve, and as a result boost will be kept sensible, and expect a little turbo flutter (also known as 'dose') on throttle lift off.
Top these basic reliable parts off with a brand new MegaSquirt Plug and Play 2 and you have a very quick, completely lag free daily, thats quiet, great value, OEM reliable and can be reverted to stock in an hour.
Upgrade path is intercooler, injectors, clutch, T25 or T28, and 3" exhaust, all the way up to 300whp.
Lets get into it.
Here is the engine bay, the car already has a Works Engineering universal intake system and a nice stainless crossover pipe, and a full 2" mandrel SS exhaust and Wozzahs excellent headers.
This is an SE stock turbo, the Garrett T02 being used, and a Garrett GT2560r (AKA T28, stock SP, japspec S14 and all S15 turbo).
Remove the intake.
Remove the headers, These are from Warren Heath Performance (username on Auscartalk Wozzah1975), these are about a year old, and still look great, in coated mild steel these wont crack like stainless headers are so well known for, and fit perfectly every time, they also work great through the mid range and top end with stock or near stock cams.
Here is the first little bit of money saving, this is a stock header exhaust flange, cut from an OEM na6 header and cleaned up, given a coat of paint a year ago to protect it. This saves over $100, its not bling bling but thats not the point here.

Don't forget to head over to DIYautotune and order your megasquirt.
This is a full standalone ECU, out of the box it will plug straight in where the stock ecu was and run a stock car, however it will need tuning to get the most from it on a stock car and should at least do a run or 2 on a dyno with a wideband to ensure the tune is safe. In this case we also ordered the AIT (Air Intake temperature) sensor, so we can delete the stock air flow meter.
A good ecu is the difference between a car that is 100% bulletproof reliable, or not.
Its the difference between getting stock economy, or not.
Its the difference between great driveability or a lumpy flatspot filled experience (just ask the intake/exhaust/boost stock ecu MSM owners)
Its the difference between having a future upgrade path and proper tyre shredding torque, or not.
This will allow us to get away with no intercooler for now, and still make good power safely, using bandaids alone you are stuck with a very weak, very poor very low boost tune, this is why the greddy system uses 4psi only. Once this gets on the dyno we will know, it may well be happy to run 10psi, with a very conservative tune, despite not having an intercooler. Without a good tuneable ecu you are stuck with bandaids like rising rate fuel pressure regs, running super low boost for safety, and a car that drives rubbish.

you state PROPERLY TURBO THIS CAR FOR 2K
you make it sound like you're about to actually do that
then you state that it won't be running like 50% of the parts to properly turbo a car, but rather the most bare bones of basic "starter" systems and be upgraded from there, after you've completed your "mission".
Am I understanding that correctly? If not, please do explain.
So the bottom line is: I applaud you for taking on this task, and attempting to do this on a budget without bandaids, but for the love of turbo miatas would you please stop making it sound like you're about to do something impossible? No one ever said you can't piece together a basic barebones system for under 5k.
This kinda sounds like your claims to achieve the impossible: "FIT A BW EFR TO A MIATA USING A BOTTOM MOUNT MANIFOLD"
-except neglecting to tell people you're doing it on a right hand drive car and don't have the main obstacle, the steering shaft, in the way.
****EDIT:
and before you start crying and call me a hater, here is my FIRST build thread from beginning of 2009, where I did what you did but for 2500, except I didn't leave anything out: full exhaust, fmic, injectors, bov, ems, etc etc etc. a whole PROPER turbo setup:

Please note 18.
Im in Australia, not only is our market COMPLETELY different and having only 4000 NAs in total is much must smaller with much much less competition, our dollar is worth a fair bit less, and our parts have to get shipped to the other side of the planet first.
Also, cut and paste from the Aus forum, so some bits wont be applicable (Ive proof read it to swap the name of the Mazdaspeed Miata for example, but not all will be 100% relevant in your country).
its been said many times you cannot possibly turbocharge an NA in a correct reliable way for anywhere near this price in Australia. Well Im just showing that it can be and exactly how its done. For the record, its basically complete however Ive lost a post and am waiting for that to come back, then Ill post another 10 updates across.

Here is my answer to that question from over there also regarding what to consider a 'proper' job.

For interest sakes for those playing at home, a full SS piping setup with a 300whp capable front mount with everything you need, is 500 dollars for an MX5, if you supply a BOV (Im only going to order it online like you so you might as well cut out the middle man) ill fit it in any configuration for no extra cost. So add that to it.
But that Isnt the point, you can add 100 things to the 'do it right list' that simply aren't needed for a reliable bump in power of 40-50%. You could add that it needs a BOV, the car with this turbo from factory never had one. (ET pulsar)
You could say it needs an intercooler, again, nissan didnt think so for the ET pulsar.
You could say it has to have an exhaust bigger than stock, again Nissan Disagreed.
And the stock na6 clutch if in good nick will cope just fine.
Anyways, everyone hold their horses Ill put more photos up as the day goes on.

IT CAN'T BE DONE IN AUSTRALIA
Got it.
Okay, I'll give you that. I have no idea what its like over there, so carry on.
Just remember: you said yourself " PROPERLY TURBO".
Then you go and justify every single statement that literally contradicts your original one.
Confused?

Good, I already know this is possible if you can weld, and you're saving even more money than be because I was factoring buying the flanges.
You can do it on LHD too. I would never make a jig off of mine because I bet it wouldnt with in 50% of the cars out there. You could easily raise mine a 1/2" and fit every car.

thats still kindof alot of heat... and when that TB closes, thats 5psi backpressure against the turbo, which may seem miniscule, but still long term damaging
i mean, i see what you are getting at, but i dont see this being an efficient reliable LONG TERM thing, might run into problems a little down the road.
what i DO see, is this being a possibility WITH all the necessary parts (ie:bov, intercooler, piping) if you can source the parts cheap, and do a diypnp for $400 or so
$400 diypnp
$100 for injectors (whatever size you decide necessary)
$100 for decent condition TD04 (or equivalent, assuming one can be sourced)
$100 for decent BOV
$200 for good intercooler AND piping (only thing besides the turbo itself that i would source from EBAY)
with some welding skills/experience $200 or so in materials (flanges, piping (maybe cheaper, depending on sourcing and connections)) +time to piece together and weld.
We are at $1100 now, with some decent condition sourced parts. $1400 if you decide to buy an already built MS.
also, ASSUMING you had Fabrication skills and necessary equipment, a downpipe can be made within $200 easily
leaving $400 to play with, that can be used towards a Better turbo option, or whatever you choose.
this is ALL assuming you can source those particular parts within those price ranges (usually can be done) and again, that you have the time, fabrication skills, and equipment to do it all yourself.
May be used stuff, and by all means NOT necessarily ARTECH quality or whatever... but all of this seems like a better option than running a NON cooled charge, with no relief of backpressure from the turbo.
by far NOT the best setup possible, but still reliable with NO bandaids, and just as, if not MORE efficient, than the 2k setup without intercooling or bov
As i said, this is all being extremely budget concious, and having access to the fab required to pull it off. I by no means claim to know everything about turbos or miatas, but i can definitely see all of this as an option.
And i realize that this may not ALL be attainable QUICKLY, but just since February, ive seen these parts for THESE prices here in the FS section of just Miataturbo. so, may take time, but if you are patient, you can source it all, and do it just as i listed.

I think his main thing is baing in AU and apparently they can't source parts as cheap as we can here in the USA.
Apparently.
But even with that obstacle, you just can't say you're PROPERLY turbocharging anything and then brush off like half the parts as "unneeded". That's just ignorant.
And no clutch? really?
At this rate you can buy a used greddy kit at like 800-900, add a mspnp and cross over tube and be done with like $1600 spent.
oh okay
so it will be reliable. it won't be reliable but it will be reliable. it might put wear and tear on the turbo and possibly the throttle body leading to premature failure, but it will be reliable. just not reliable.

The setup has a BOV fitting welded to the crossover, Add 20 bucks for a Bosch bov and quit whining 18, when I get another 50 photos up with instructions on the fitment, checking the turbo, porting the wastegate, and how to fabricate the parts, you will understand the point is instructions and showing what can be done on a budget, first time, no chasing used parts and guessing etc, NOT to argue with you about every minute detail regarding what I can buy if I live in the states from the forum if I wait a year, we all know what can be found in the classifieds.
Let the thread just continue man.

As i said, this is all being extremely budget concious, and having access to the fab required to pull it off. I by no means claim to know everything about turbos or miatas, but i can definitely see all of this as an option.
And i realize that this may not ALL be attainable QUICKLY, but just since February, ive seen these parts for THESE prices here in the FS section of just Miataturbo. so, may take time, but if you are patient, you can source it all, and do it just as i listed.
AGAIN... its alot of assuming..... but definitely possible
i mean, i see what you are getting at, but i dont see this being an efficient reliable LONG TERM thing, might run into problems a little down the road.
what i DO see, is this being a possibility WITH all the necessary parts (ie:bov, intercooler, piping) if you can source the parts cheap, and do a diypnp for $400 or so
$400 diypnp
$100 for injectors (whatever size you decide necessary)
$100 for decent condition TD04 (or equivalent, assuming one can be sourced)
$100 for decent BOV
$200 for good intercooler AND piping (only thing besides the turbo itself that i would source from EBAY)
with some welding skills/experience $200 or so in materials (flanges, piping (maybe cheaper, depending on sourcing and connections)) +time to piece together and weld.
We are at $1100 now, with some decent condition sourced parts. $1400 if you decide to buy an already built MS.
also, ASSUMING you had Fabrication skills and necessary equipment, a downpipe can be made within $200 easily
leaving $400 to play with, that can be used towards a Better turbo option, or whatever you choose.
this is ALL assuming you can source those particular parts within those price ranges (usually can be done) and again, that you have the time, fabrication skills, and equipment to do it all yourself.

This is totally doable... My setup is as follows:
Used Greddy Kit with TurboTony Downpipe $500
3" custom Catback with Magnaflow muffler (DP6061 style) $200
DIYPnP $350
RX8 injectors $60
TurboXS RFL Bov $25
ABD Front mount for MK4 VW 1.8t $100
IC Piping $150
FlyinMiata Stage 1 clutch $350
PLX Wideband $100
I'm at $1835 for my setup... Add $100 for miscellaneous vacuum lines, fittings, etc and I'm under $2k.

Enough with the mini rant, thank you for taking the time to post this. However, I would make this is build thread rather than a "how to" since many people will disagree with your choices and there is a million ways to build a turbo system with none being the absolute correct way.
My suggestion for a $2k range build, Begi-s kit, with a used sr20 t25 and megasquirt with wideband. With the price Begi takes off for the turbo and FPR it should put you right around that price for a non-intercooled reliable 6psi system.
or the more fun method of trolling the FS section for good deals for a year to piece together a kit. Mine will be about $1200 with BEGI mani/DP, MS, injectors, intercooler and gt2560 when done (i hope...)
