DIY Turbo component sourcing thread!

[jvanzyl]

Want to introduce a bit of forced induction into your car? Look no further! For the MR2ROC club is here to create a list of all the basic components you need and where fabrication is required, sources and costs indicated  :-) :-) :-)  First priority would be UK sites, but understandably a lot of stuff is in the US...

What you need:

KNOWLEDGE
The following books are a good read on this topic:
How to Turbocharge and Tune Your Engine  Authored by J. R. Crosby

The following site seems to have a lot of good info on the topic within the forced induction section:
 m http://www.enginebasics.com/Advanced%20 ... uning.html m

The below thread contains some useful advice specific to turboing the MR2.
 m http://mr2roc.org/phpBB3/viewtopic.php?f=7&t=60040 m

Items below have been given a priority (Needs, &  might need to buy)

What you must buy at a minimum:
Turbo

Engine mgmt
  Piggy Backs
       - eManage Blue
             £346 for the EMS alone
               m http://www.garagewhifbitz.co.uk/greddy- ... e-ecu.html m
              Please note that these can be purchased second hand with relative ease - however care must be taken to ensure you obtain the correct wiring. Prices in the region of £250.

        - eManage Ultimate

        - Dastek UnichipQ

  Standalone More expensive but more power possibilities?
             - Apexi
             - AEM
                Funky Power £695
                 m http://www.funkypower.co.uk/catalogue.p ... STEMS&man= m

  MAP sensor for ECU


Also  - you will need to have the ECU/Piggyback system mapped on a rolling road. The costs vary for this service but are in the region of £400 and hour?
The following locations offer mapping:
 - Redline (Essex)

Monitoring
EGT
Boost gauge
Oil temp
AFR
oil pressure

Downpipe

Wastegate

blow-off valve

Oil lines

Oil return bung into sump

Sandwich plate for oil feed or pressure switch extension adapter for oil feed

Hose clamps
You can never have enough hose clamps... and even when you have plenty they wont be the right size!

Turbo manifolds
Water lines

T-Piece for water feed (if water cooled turbo)

Intercooler pipes

Intercooler

Exhaust

Charge cooler + radiator

Boost gauge/sensor

Injectors

Colder spark plugs

Air intake

Might have to buy:

Fuel pressure regulator
Turbo timer
Oil cooler
Thermostatically controlled oil cooller can be picked up from the usual subjects for under £100
Oil catch can
Upgraded radiator fans
Larger radiator
Boost solenoid Boost controller?
Wideband sensor
Wideband monitor
As you increase in power and torque past X/250 lb/ft you will need to invest in:

Uprated clutch (depending on target power).
Uprated gearbox

Built internals.
Forged rods and low compression pistons. - going nuts now and aiming at 350hp+
alloy fuel rails with returns. Better flowing intake manifolds and throttle bodies. etc.

[shnazzle]

Depending on how thorough of a job you want to do this list could be extended.
Charge cooler + radiator
Fuel pressure regulator
Wideband sensor
Boost gauge/sensor
Injectors
Colder spark plugs
Air intake

ah awesome! would be good to indicate which things are necessary and which things are a nice to have - if that's even possible!
Will add these to the list!

If buying a new ECU, do you not need to have the ECU mapped, therefore do you not need dyno time?

Eh? Explain please

Ah! Good point! Yes I'll add that in...

[MR Roadie 2]

Eh? Explain please

Once the ECU is fitted do they not need set up and mapped? or is this only stand alone ECU's?

This is a DIY install. Meaning that if you bought the ECU, it won't have a map on it. And even if you got it second hand from someone with a similar setup, it would likely still need mapping.
You can run very low boost without a map. But to finish the install you'd have to calibrate and tune the ECU. Whether it's piggyback or standalone.

How do you calibrate and tune a ECU?

Dastek UnichipQ  is another ECU. Redline in Essex specialises in these and is what Matt put in the SP240 kits (with additional components).
MAP sensor for ECU...gotta read boost into ECU somehow.

By wastegate do you mean the "dump valve" or blow-off valve? The wastegate usually sits on the turbo and controls how much boost the turbo makes and the blow-off valve relieves pressure from the turbo when you lift off throttle in order to keep the blades spinning and prevent massive back-pressure.

So, add blow-off valve to the list. This can be either recirculating into intake or vent to atmosphere (which we all prefer because it sounds so damn cool  s:) s:)  )

Boost solenoid - Linked to ECU or electronic boost controller to control how much boost the turbo and wastegate see. So if your wastegate is set to 6psi, but you want to run 10psi, you use a boost controller and solenoid to pass less pressure to the wastegate, so that the turbo goes on to produce the extra 4psi. Alternatively, just use a manual boost controller

Uprated clutch (depending on target power).
Uprated gearbox (if over targetting over 250-260lb/ft torque).

Built internals. Forged rods and low compression pistons. - going nuts now and aiming at 350hp+  s:) s:)  Looking at alloy fuel rails with returns. Better flowing intake manifolds and throttle bodies. etc.

OK I think you're both saying almost the same thing - with the point of differentiation being that Patrick is saying that you can get away with NOT mapping the ECU whilst running at low boost?

You assume I actually know what any of that is! Dude, I'm literally copying and pasting a "list" I don't understand it other than the sum total when installed make the car go faster!

I meant more to limp to the nearest trusted tuner to map your ECU  s:) s:)  hehe. Basically running the stock car but with a turbo in between and not allowing it to build much boost at all so that your stock ECU can still fuel sufficiently without it under-fueling and causing detonation all over the place.

I don't know. Maybe I'm missing something but if you're going to put a turbo on the car, you're going to have to change the way it fuels/times/etc to get the best out of it. There were kits that used the stock ECU but frankly I find that dodgy at best. Aside from the fact that you'd have to disconnect the knock sensor, which is scary.

haha!! sorry. Ok, maybe best to start at the beginning then

I had a recent thread with 2 manifold options within the EU currently the states is way too much money unless its the only option.

You can map the car yourself. Plenty of people do it and their cars dont explode. However for me personally a dyno session is a must.

Well if you're able to provide the links to the manifolds that'd help!

Funky power do a AEM standalone ECU.

Cheers - I've added that!

Oil cooler
With the added temperatures of the turbo.  I would seriously consider an oil cooler
Thermostatically controlled oil cooller can be picked up from the usual subjects for under £100

Hose clamps
You can never have enough hose clamps... and even when you have plenty they wont be the right size!

Turbo manifolds
Several available on ebay along with some 1ZZ Kits tho these would need some fettling to fit as they are normally for the Celica

As most people know i am running an Sp240 turbo kit.
Even though its a stonking kit i am always at ways to make my 2 faster.
On my many google searches i come up with a few things that seem good value but i wonder if i am missing anything.

 m http://www.retroturbo.com/?product=garr ... -gt28r-t25 m
626 for a gt2560 looks good value or have i just been looking in the wrong places?

 m http://www.turbomotor.dk/contents/da/d28.html m
123 for a cast 1zz t25 turbo manifold

Or

 m http://tuning-parts.bg/manifold/1324/ m
94 euro for a cast t3 manifold

 m http://www.ecumaster.co.uk/ m
Anyone have any first or even seconhand knowledge of the above.
They do a stand alone ecu with some great features for a cracking price.
Finding somone trustworthy to map it could be an issue from what i have read it is made in poland and the software is written by an ex lotus guy.

Any thoughts.

Is that what you were looking for?

Oil cooler

With the added temperatures of the turbo.  I would seriously consider an oil cooler

I will have one as i am planning on upgrades but there is no need really imho. Up to 240 bhp i reckon you only need the bear minimum of kit.

This thread is the one John

This is exactly what I was looking for! Will add it into the list as soon as I can put the kids down and get some time! Brilliant, thank you!

[shnazzle]

Can we please keep this to a list of required, optional and possible parts and stay away from advice and do's and don'ts?

There are far too many parameters to summarise in one thread and as 90% of turbo installs are different from others on here it's best looking at each separately.

Totally- I will need help telling which falls into each category though!

When I can find my Notebook (a real paper one) I'll post up my scribblings.... I basically did this when I was looking into Turboing/engine swapping mine.  Lots of links and prices etc

Not a problem  s:) s:)  And thanks for compiling a nice list!

Remember MR2ROC is an "enthusiast" club, not an "expert" club. Although a few on here could definitely be classed as such and have the credentials to back it up.

I wouldn't take a word I say for truth, for example. I'm only just an enthusiast who happens to read a lot and have a turbo mr2 in the house

[andy bird]

I'm going alittle more basic for mine

Tubular manifold with T28 turbo from 200sx. 6-7 psi.  Use the 200sx elbow which has a lambda bung in it. Then have a join up piece to go to the exhaust I have already fitted.

No water feeds but oil feeds so lines, oil return pipe and feed required and Sandwich plate.  Oil temp and pressure gauge from here as well.

No intercooler but water injection boost actuated, maybe 50% methanol maybe not.

Blow off Valve obviously

BLITZ R-FIT fuel computer, Corky maf mod and 2zz injectors.

Colder plugs

Looking at the available kits they run lower boost with no management.  The only thing I'm not sure of is what the ecu will do when it sees boost but as I said I think it's the PE kit that doesn't run any management at all.

Wide band as well would be fitted for fettling. I'd be relying on the stock knock sensor to pull timing as required  but running water injection with methanol is great at reducing knock
