fueling and oilways problems (fitting a std t3 setup)
Turbo Mini Forums

hi there,
ive recently purchased a FULL t3 conversion (standard metro stuff not fancy gear) to fit to my standard 1.3 metro :) ive come across a few problems i cant seem to work out though (i have used the search function and current builds to check some things which have been a GREAT help) ... however there are some question for these few things i cant find answers for.

1. ive taken the carb and manifold off my metro ready for the conversion , started with swopping hoses to the turbo carb ready for a mock up before the lines get upgraded e.t.c.
i swopped the choke cable and the vacuum and then hit a problem.. i realised the mounts for the choke and accelerator on the turbo carb are differant to my standard carb, am i ment to swop my std items onto the turbo carb so the accelerator cable then fits?

2. after looking through 4 years of mini world and mini mag ive worked out where the top oil hose goes to (the hole just below the block to oil filter housing) is this correct?
But the lower ''return'' hose im baffled by... i have NO idea as to where it goes, im guessing the blank at the bottom of the block, but ive never seen a hose (or similar) to go to here? ive only seen the top feed hose in minispeed or avonbar

3. i have purchased a fuel pump and a fuel pressure regluator BUT working out there positions has been some what of a hard task to say the least!
i cant work out what to do with the standard machanical pump as surely this will slow fuel delivery down if used with the aftermarket parts?
Do i bypass it and fit a blank or do i use the standard pump aswell as the aftermarket fueling parts?

sorry for all the questions, im just abit puzzled by all these things, if you have links i can read on these instead of typing them up they will be greatly apreciated also, thanks

p.s. this is the car that everything will be going on, ok its abit of a work in progress at the moment but it si getting there

Just to add, anyone local to lathom, lancashire that wouldnt mind popping down for abit helping out for beer tokens it would be greatly apreciated

2) My oil return from the turbo goes to the blank and works perfectly.

3) Is the new fuel pump a high pressure pump? and i removed the mech pump and plumbed in the electronic pump and mounted it under my boot and fitted my regulator also under the car near the front wheel so its easy accessible if it needs replacin, u'r fuel lines will also need to be upgraded to handle the pressure of the fuel.

Hi,
1) Don't know never fitted a turbo carb, but no one has ever mentioned this before. Won't the cables just fit to the linkages that are on the turbo carb already?

2) The oil return goes to the hole in the back of the block where the mechanical pump was. There is a proper plate (with a pipe) for this job, but I don't think you can buy them new? Then you need a 90 degree hose to connect it to the turbo. A normal silicon hose is not resistant to hot oil!

3) Are they turbo pump and regulator? Nothing else will work right.
You'll need to run a feed and return pipe down the length of the car. People use micro-bore central heating copper pipe from B&Q 10mm I think?
Regulator on the bulkhead, not to far from the carb. There a diagram on how to plumb it in on here
Fuel pump goes level with the bottom of the tank, you'll need to modify your tank to work with the new pump for the best results.
Mechanical pump goes in the bin!
Cheers,
Gavin :)

My Mini build diary

thanks mate,

1. on all the carbs ive got (hif38/44 non turbo) there is a small groove in the fixing for the accelerator cable to go through then into a fixing, on the turbo carb its just flat plates. one looks correct for the choke but the other doesen look right, i can get a pic if it helps?

2. OHHHHH! ive got a small piece on the turbo and another (very similar if not the same) that i now think must replace the pump, its a flat plate with two holes either side and a pipe in it that goes out then up... this osviously faces the turbo
Im ordering all my I/C and turbo hosing from deamon tweeks (sfs or samco depending on prices ) so i will mock everything up with what i have them check everything over.

3. yep its a turbo part or more of they both are, i will go read the packets later and i can tell you what they are, the name has escaped me i cant think of it.
I have all the hosing and its is the central heating stuff i think (a slightly milky white fairly rigid pipe)
Now i know what to do with that bloody mechanical pump everything fueling and oil related is preety much sorted

Thanks gavin, helped alot!

Cheers
Ben

Thanks tweaked, with regards two it was that i was abit struck with.. i didnt no where they went on the block haha, i understand it abit better now thanks

I dont like the sound of the pipework you propose to use as it is plastic of some sort which may or may not be long term proof against fuel.Most people use copper.

If it's central heating "plastic" pipe you're thinking of, I agree entirely with tadge44... DON'T.

If it's the correct grade of nylon fuel line tube - like most modern cars use - then no problem.

I'm running mine in nylon, but NOT central heating plastic.

Most people though, choose to use copper central heating (small bore) tube.

Schrödinger's cat - so which one am I ???

hmm, i will have to check it. i got it when i bought the kit off a mate so i may ask him what it was, it appears to be a plastic type construction, but i will ask to be on the safe side.


These are the the two carbs ive got, the top being turbo the lower the std metro unit. At the bottom of the pic you can see the fixings the turbo one has the choke mount but not the acellerator mount, i tried swopping them over but it hits the inlet so i cant see what im ment to do?

Edited by MINIMON on 25th Oct, 2008.

the throttle cam is just on the other side of tha carb?

no need to do anything is there?

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

there isent a fixing for it thats the problem, the mounting on the plate between the inlet and carb is there for it to be on the other side but there doesent appear to be a ''cam'' if thats what its called?

i tried fitting the piece off the other carb to that side and it didnt seem to fit due to the inlet manifold :-?

i think i have a part missing... random question but do you have a piccy of it or have you got a pic of a carb from that side you can post up please.

p.s. does anyone have one they want to sell hehe

alright mate had same problem with rev cable i went to local scrapyard and took one of another car i used one of them threaded bar types with the 2 nuts cable goes through middle dont know name of them but do you get my drift had to look for a while as most are bigger and wont fit in grooves

only mocked up when i took this pic, obviously the sandwich plate to secure the cables is missing

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

THATS GREAT! (yes caps needed haha) i could probbaly nock one of them up, i was under the impression they were suposed to have a small dish like all other accelerator cams have

and just to add the hose i have is 30 metres of 7.5 internal bore nylon hose

you lot had me worrying so first thing this morning (9 o' clock) i shot into the workshop to check out the hose haha!
Its all cable tied to the roof streightening out now

Thanks guys, oh actually i knew there was something else.
The oil return fixing that replaces the std fuel pump, when you fit the plate are you suposed to use the small plastic spacer off the std pump as i have?

Not necessary

helpful... lol its on and seems to be fine with the return pipe (the turbo is loosely on)
it was just the bolts i used were the std fuel pump ones and they had a smooth bit at the top which wouldnt of bolted tight enough without a spacer

Own the day

thanks about the shoulder thing mate, its all fitted and sorted.


If you read what i was asking about the carb properly you will see i was asking if i coudl swop the STANDARD throttle cam onto the TURBO ONE as the TURBO ONE doesent have one...

i AM fitting the turbo carb, i was just asking if i could fit the STD throttle cam, joey explained what i needed though and the pic was worth 1000 words :)
i will try to source one, if i ahev no luck i will nock one up

Thanks again

OH-OH! ive just read elsewhere on the forumt hat a redtop fuel pump cant handle more that 3.5 psi, is this true?

I think this is the pump i have

Thanks

Hi,
The only pump that will definately work properly is a Metro turbo one. These are a roller cell injection type pump.
You could use an MPi tank with the built in pump instead :)
Cheers,
Gavin :)

its all going in a metro though... :lol: i cant fit a MPI tank im just going to either find a Turbo sender with return feed and a fuel pump off a turbo or try and use the facet red top i have

The thread for the car is in the show us yours section

Edited by MINIMON on 29th Oct, 2008.

mon, have a search in the 'how to' and faq section, all these things have been answered a million times over

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

i cheers dude, i was just on that i was going to edit my post and u had already replied, i feel a n00b now lol thanks for that :p

Thats the one ive got, i should be fine as im only going to be running 5/6 psi with it being a standard engine.
im setting everything up ready for a worked 1293 ive started building. im setting it up now so i can see what the quality of a few parts are like and to iron out any small problems before the bigger engine comes into play. :) less to worry about then i suppose
