i got a T34 with .63 ex housing on it, and tonight i took the ex housing off.

the shaft has 2 something 7 stamped on it, i cant tell the middle number cos there is a hole in the end of the shaft.

now ive heard that maram shafts are 247 - is that correct?

it looks like either 217 or could be a 4 but i can only see the the very top of the middle number, but its closer to the 7 than the 2 if that makes sense lol?

i know maram shafts are non magnetic, but i aint got a magnet to check lol

bud-weis

my .63 housing has no markings whatsoever on the turbine wheel? so i guess yours must be maram'd up just run anti lag and see how long it lasts

Maram Shafts are non magnetic as you say.. Also they are 247 not 217

Micky The Finn

may have 247 stamped on the end,or and isnt magnetic,

Micky The Finn

beat me to it.

guess i need a magnet lol

my mate said his T34 didnt have any markings at all on it.

ill try and get some pics up but it wont be till the w/e

fookin bonus if it is.

PS will be running ALS regardless lol

oh, also, one more thing lol

on the main body bit of the turbo, it has a silver coloured screw in it, looks like a flat blade screwdriver insert into a splined outer bit thats screwed into the cast bit, what is it for? - no sense again - deffo need pics

markk

iTrader: (2)

thats where the font insert has been fitted when the restrictor was removed

Fudgey

iTrader: (4)

you what?

got any pics at all?

i bought it having supposedly covered 100 miles.

but it does have FOOK ALL play in it, and looks like its pretty new.

so cant imagine its been used for rallying.

so could it be a maram shaft?

i need to learn lots about turbos asap

Charlie Chalk

iTrader: (1)

For this blue thing = Restrictor

Micky The Finn

i once did 16 miles with a brand new one and blew it to peices,rather the T6 als did.

Micky The Finn

how did you get the gorrila to stay still so long while you rested the turbo on its knee?????????

bud-weis

did any T34's come with different sized compressor housings?? cos mine seems bigger than a mates ( just at the inlet throat ) i know it's bigger because we tried fitting a boost hose off his onto mine and it wouldn't go??

Charlie Chalk

iTrader: (1)

Not my leg, Ask Red16

Charlie Chalk

iTrader: (1)

Some are T3 size 60mm iirc some bigger 70mm i think, Not sure

RobCarden

mines like that - i had to use rs500 hose - same size as the rs500 intercooler outlet

markk

iTrader: (2)

so youve answered al your questions !!

it was a motorsport turbo, so you will need to have an inlet made for it

Fudgey

iTrader: (4)

rad its not like that on the inlet, its round all the way err round

what i meant was the main body the shaft goes in, not comp or ex housings, you see the oil feed in that pic, in the middle beween that and the water feed is the silver screw thing im on about. i really need pics, but aint got none yet.

Markk - still none the wiser lol

markk

iTrader: (2)

that blue bit needs to be removed pal , have a look at it internal diameter, it will be 34mm, as per rallying regs, so it needs to be opened up mate, to more like 60mm, other wise you'll have a hell of a problem

Micky The Finn

or lots of torque!!!!!!!!!!!!!!!!!!!!!!1

markk

iTrader: (2)

well you know what my answer would be, i actually prefer an engine that will accelerate within the current millenium

Fudgey

iTrader: (4)

no no, you dont understand what im trying to explain.

mine doesnt have a restrictor, its got a normal looking inlet bit, ie about 1/2 an inch longer that the pic rad put up if you ignore the blue restrictor.

the silver screwy bit im on about is between the oil feed and the water feed, tapped into the main housing bit that hte shaft passes through.

as i said, a pic will speak a million words lol, but i aint got any pics...

markk

iTrader: (2)

get the pics

Charlie Chalk

iTrader: (1)

Pics

Micky The Finn

pics of your sister will be better,or cousins etc....

Fudgey

iTrader: (4)

no sisters sorry, and counsins are male too

i guess its one for dave PICS OR STFU

CliffRS4

iTrader: (1)

I think you might mean that it has a space for an Exhaust gas temperature or lambda sensor?

Fudgey

iTrader: (4)

cliff, quite possibly mate.

the ex housing has a bolt in it,about M10 or 12 so i guess thats for lambda?

but the one in the main housing im not sure of

defo defo need pics

Tony Ryan

You can usually see the 247 stamp in these quite easily , heres one of mine in a T4

Anonymous

That fits his description of "looks like it might be a 1" perfectly

Fudgey

iTrader: (4)

cheers Tony, it does look kinda like that but id say the middle mark is a bit closer to the 7 than the 2.

ill try and get some pics tomoz but not sure if ill get time to go over where it is.

also the numbers are nearer the middle of the shaft too.

and the blades look different but if its a T4 then i guess they prolly would lol.

Fudgey

iTrader: (4)

ok, we have some pics now lol





and this is the silver screw thing i was on about that goes into the oil way by the shaft. whats it for?





compressor wheel



and comp housing says .60 on it inside, also says M27 on the outside.

Fudgey

iTrader: (4)

oh yeah, and the shaft and wheel are NON magnetic

markk

iTrader: (2)

that my friend is a pukka group a turbo !!

it is a mar-m shaft, and the little blank you have is for measuring core temp and shaft speed

Fudgey

iTrader: (4)

sweet, cheers mark

how do they measure shaft speed tho? i didnt see any lobes or anything on the shaft?

markk

iTrader: (2)

its measured for optimum operating speeds and so as not to overspeed the turbine, as for how, the last one i saw was an optical sensor on it but i never saw what they had on the shaft to pick up from, could be the gap in the front ring

How much are these worth in good condition?

I paid £200 4 mine cheaper than a t3 recon

Fudgey

iTrader: (4)

markk

iTrader: (2)
