So, just purchased my Garrett GT2554, Obx Sump, waiting for a reply for the T25 manifold (unless anyone has one spare?). Cars in for MOT and Exedy stage 1 clutch next week. waiting for a reply from charlotte at rrrengineering to get an idea of lead times for booking in for ECU and Mapping.

its finally underway!!

I will produce as concise a list as possible for those wanting to complete a turbo build.

watch this space!

Good work, everything coming together nicely

This is going to be an awesome build.
Great turbo for a stock 1zz these make over 200 @ the wheels on M X 5s and probably more on a 1zz with a great ECU and tune.
Wickedly quick spool.
And if you ever decide you want more power pretty much a straight swap for a GT2860RS.
Although you would need to forge the engine.

What actuator or spring is included with the turbo?
Don't forget an oil feed restrictor.
Pretty sure this is needed with ball bearing turbos on a 1zz due to high oil pressure.

It's going to eat TTE and SP turbos for breakfast.

I'm looking forward to this a lot!!

A lot of thanks to all of you guys who have been advising me. Even up to this stage I wouldn't have such great choices in kit if it weren't for the experience I've been offered.
I'm just getting the internally wastegated option so couldn't really tell you  :-\ must remember to get one!! Lol.

I was just thinking that if the default setting on the wastegate actuator is 14psi if the boost solenoid stops doing its thing then you may end up with a blown engine so it would be better to have a 7psi spring.
However with EMU BLACK it's probably got safety's built in anyway.

Hmm.  I don't know if this is a thing but you can wind out the actuator and adjust he boost on spring pressure? So my plan to get from Southampton to Cambridge was to basically wind it out  so I was effectively bypassing the turbo or running 1-2 psi max.

I think I read somewhere that they come 7.5 psi stock. Will confirm today.

Thanks for pointing this out!!

7.5 should be fine and what I'd expect that turbo to come with. I'd still do your best to stay out of boost. Your best boost control is your right foot.

I'll put a brick under the accelerator  :P

Just been quoted £150 to fit my Exedy stage 1 organic clutch that cost £265(tmsmotorsport) by the guys down at Hendy performance. quite luckily know them through family. Cars booked in for the 10th for clutch and MOT.  Also after chatting to their Tech supervisor I've found out they are actually a pretty high spec garage who have recently refurbished and sold Colin Mcrae's Mk1 focus!! I'll let you know how that goes although I imagine they will be highly recommended to you southerners!

Struggling to get in touch with the Danish company for the t25 manifold so will look to get the one from Bulgaria and get a T3-T25 adaptor.

That's all so far

Advice required.

Are siemens 630cc injectors too excessive for 200whp. or will they just run comfortably? can get a set with adapters for £160 new.

440cc would be good enough for your application.
That is a good price for a set of 4 with adaptors.
Are they a straight swap?
Toyota fit denso injectors to most of their engines.

There is a thread here saying that they use them. just the plugs that are different.  these come with EV1 plugs and connectors so just Denso female connector req'd and some wire to knock out some adapters.

so are you saying that they are too large  i know that 470s from the VXR are recommended but will there be any ill effect?

No ill effect that I am aware of.
If you had a piggyback ECU then they would be too large but with a full standalone you are fine.

Assume you have read this?

yeah thats the one i was referring to.

its where i decided to check out the siemens Deka.  will purchase those now  :D

parts list coming along nicely..lots of shinies being delivered  :D

many thanks @1979scotte

Had to bite the bullet. £270 for the cast T2 manifold from Turbokits. He knocked £20 off total frice which should cover some of the tax.

lots of shiny bits arrived at home but ive yet to lay my hands on it. gonna throw some seafoam in the oil as ill be dropping it when putting the sump on anyway so may aswell clean the insides before she get another hundred ponies going through her.

Powerflow swindon currently cant do 2.5" pipes  :( so need to phone next week to see if theyve got their act together.

picking up oil,filter and spark plugs from halfords this weekend (trade card  :D) then thats me with everything except the intake pipework (which i think will be half the battle!) and exhaust.

have a very concise list and so far have spent £2812. thats including ECU (with map and fitting) probably over budget slightly but when arent we. 

Few questions to those who made it thus far.
Whats the O/D of the non return valves required?
if im running a wideband will i need the stock lambda sensors using an ECUmaster standalone?
Where the hell to Vac lines go? its probably the thing im most clueless about and researching makes no sense  :-\
wheres the best place to plumb in an IAT?
Does MAF disappear completely with standalone?

Theres probably more but my head hurts  (:< >:)

thanks in advance guys

Dan I think your in Southampton? have you tried southampton wheel and tyre in totton? They are a powerflow dealer. I used them for a repair on my Janspeed and they did a good job. They do some pretty high end cars?
2zz by Rogue. Se7en cams. BMC CDA. Competion clutches lightened flywheel, Megillian Racing Exhaust. TRD sportivo suspension and ARB\'s. TRD braces. TRD quick shift. TRD dash kit, Matts brace. Getting there but not sure when it will stop!

dan944

Cheers mike,

weirdly i'll be doing all the work in lyneham as thats where i have access to a workshop.

thank you though. depending on how my temporary exhaust is i may take her home.  always prefer local  ;D

Would be good to see your build at some point. Just up the road from you when your in southampton.

Im planning on getting to as many of the meets this summer as possible for ROC, MR2OC and MR2DC so hopefully we'll cross paths at at least one.  if not we'll hold our own southerners meet :D

IAT would be after your intercooler.
MAF can go in the bin and I am pretty sure you bin the normal O2 sensors.

Vacuum is for your blow off valve, boost controller (port at the back of the EMU), brake servo (don't have to worry about the obviously) and a rising rate fuel pressure regulator if you were to get one (very much advised but not required at all)

Btw I paid 3k fitted for a secondhand turbo kit that wasn't anywhere near as good as this is going to be.
Btw have you looked into insurance?

Thank you @shnazzle, do I just get a vacuum block and stick them both into that? or as I only have two can I just plumb the ECU to the BOV direct?


@1979scotte that makes me feel a little better.  The manifold price is a bit of a stinger but in total its not far off what I budgeted for, and I have got some pretty good quality parts in honesty. insurance has more than doubled  :o to be expected I suppose.

Will be nice to see what the 0-60 times are on this when its done, will use the OBD reader to time it.

More questions,
Compressor outlet is 2". Throttle body is 3". I was thinking a 1/2" step up straight from Compressor then another one before throttle body. or does it not matter?
Also, still need the Diameter of the non return valves if anyone knows it?

You won't need a vacuum block. It's handy if you have lots of devices that require vacuum. You can do if you want, it's cheap enough and makes it a nice clean install and if you want to add a rising rate FPR in the future you can just tap into there. In the meantime, just T-pieces will do.

Wouldn't worry about outlet to TB sizes as there will be intercooler piping in the way which won't be 3" either :)

Not sure on the size of the non-return valves. I'd have to go measure but I'm not going on in this weather hahaah

dan944

Thank you  ;D

I would NOT expect you to go out in this weather! haha

I can check this weekend when I get back to look at the car.

So...vacuum hose from BOV directly to back of ECU with a 'T' piece to boost gauge. correct?

this is all prior prep to try and make the build go as smooth as possible  :D
