So you want to go single turbo... Heres a list of things you might need.

So you want to go single turbo?! Welcome to the club.

I thought id wright up this thread to give a list to what you might need to build yourself a single kit.

diffrent goals will require diffrent kits, porting etc will also change your choice of setup but ill keep this simple as i can.

You will need:

Turbo (T4 is most popular footprint)
Air filter to fit your new turbo.
Single turbo manifold (i use 3mm ebay)
Oil lines (AN4 commonly)
Oil return lines (AN10 Commonly)
Oil return fitting.
Boost pipes.
Wastegate. (50mm is commonly used on rotary engines for most boost ranges. Also id recomend a genuine make such as tial or Turbosmart... Ive tried all sorts of ebay gates. they die)
Wastegate dump tube.
Downpipe (Generaly custom made. x2 45deg bends and a short legnth of straight. ( diffrent turbos have diffrent flanges etc)
Dump valve. (users preference whether to run one or not)
Block off plates
Fuel!- bigger injectors, pump (Direct feed (relay modification))
Adjustable FPR
Intercooler kit (FMIC or VMOUNT)
ECU (Power FC)(Adaptronic)(Link)(ME) & any tuning stuff you may want (WB, Dataloger)
hose for wastegate (id recomend 4-6mm ID)


And a lot of other stuff that will probably need upgraded if not already.

Wideband (AEM, INOVATE)
Boost Gauge
Boost controller (If runing more than wastegate pressure
Colder plugs, 9, 10,11 (depending on hp Craig TGS has made a thread for selection)
Ignition (HKS twin power) (AEM Smart coils)
Bigger Radiator
Better Clutch
Motormounts
BOV
Water/Alc injection
Full 3" exhaust
Battery relocation
Pulley kit (remove air pump)
Diff brace
Wideband (AEM, INOVATE)

So in many ways its not just a case of buying a turbo and manifold and sticking the hoor on.

Hope this helps some people looking to go single.

Every thread needs to have a little picture. Heres my messy build. not a kit in sight.

I'll add my own personal experience of single turbo transformation...

Had a reasonably decent spec twin turbo car; big FMIC, radiator, full exhaust, Apexi PFC, Supra TT fuel pump rewired.

Bought a single turbo kit for £700. I was thinking bargain! Just throw a new secondary rail on with some 1680s and off we go! Nope. I ended up spending an extra £500-750 on all the various fittings and bits needed. Of course I then had to trouble shoot a car with an all new fuel system, ignition system and turbo set up. Not cool.

I would whole heartedly recommend your upgrade path from a twins car looks like this, using the oh-so-confusing stages system so popular with tuning shops:

Stage 1
Radiator
Standalone ECU of your choice
Exhaust

Stage 2
FMIC/VMIC
Larger primary and secondary injectors
Adjustable FPR
All of the associated fuel lines to fit the above
Fuel pump and rewire

Stage 3
Beefier ignition (AEM smart coils, MSD CDi, Twinpower...)
Single turbo

EWWW dont you dare use stages.. haha. it does help to have some sort of order though! The only problem here is how much of an upgrade for you go for. Future proofing but not in a way where it would effect the current running condition. Ie putting twin GST450 pumps when the car is running stock rails and 350bhp or a big twin plate clutch that will handle 800nm torque but will ruin the drive quality (i done this) haha.

Like you say. it does cost more than you would think dosnt it. fittings and fuel lines alone can spring way past £100.


Cheers for the input dude.

Yeah, I fucking hate the whole 'stages' thing. You end up with total bellends going on about their Stage 6 Fiesta ST. It is quite a good way of breaking it down though, you don't want to end up slapping loads of parts on all at once then not knowing why it doesn't start and run properly.

The main issue with stages is each stage needs a remap. Might be easiest to save up and one winter when the car isn't in use do that lot imo!

Don't forget a fat wallet / expensive loan / high interest credit card

 

[Myocardial Infarction]

As stated a stage 1 ecu would most likely have to be a PowerFC as many of the other ecu's can't fully support the twins with all emissions etc in place. So you might end up replacing the ecu a second time if you want other options such as direct fire.

Deffinatly. Turbos nowadays are seriously impressive. When i was down at rotary revs i was playing with a couple cars with efr turbos. Arron took me for a run in his 8374. Holly christ ive never felt power like it. 2800 boosting with serious torque. I love them turbos. Just cant afford them hence going for the sxe version.

Also i should say. EBAY Parts. Yeah some are great but some parts really need to be genuine. Typicaly wastegates and intercoolers are naff. Ive tested a few diffrent styles. Wastegates alllways died when pushed. Intercoolers tend to be too restrictive or too free flowing heating up ait. Alright for drag racing or a little hit here or there. Deffinatly not for track.
