OK, the long Easter weekend was set aside to help Emma's Dad get the engine in to her turbo Cinq, but little fecker that it is my turbo Cinq starts blowing its exhaust on Thu morning when starting up to go to work, fine easy fix..........fatal last words, more of later.

Fri engine in Emma's car, all looking good, some modifications, which will be covered in Emma's turbo thread. Not look at my car, should be easy......

Sat Punto GT brakes and Sei Abarth stud conversion over form old Cinq to new, SuperSprint exhaust on, further modifications to car/engine bay (you may see a trend here).......

Sun look at my car, arg, manifold stud broken where turbo bolts, so remove bumper, drain cooling system and unbolt turbo and manifold etc, then shock horror there are cracks all over my turbo on inlet side, now this isn't uncommon, most if not all turbos have cracks, but not ones you can see daylight out of when looking inside turbo:eek: oh well need to wait till after weekend to phone turbo Technics who happen to be pretty local and see what can be done, tho at minimum new inlet housing is needed as its shot which is a bummer as turbo shaft has no play in it what so ever so turbo was healthy otherwise, so back to Emma's car.........

Mon final check over of all ancillaries and earths etc and refitting of Fuel Cut Defender and MF2 and turn over, nothing, no fuel, fill it up, turn over nothing, :bang: much head scratching, and then finally dawned on me the immobilizer was unplugged, turn over engine sparked into life straight away and idled away nicely :D

So one long weekend, one turbo Cinq dead, another raised from the ashes and sounding very very good.

ah thats a bummer,will they have housings in that size?

Yeah should do its not a custom thing or anything but there are 4 different kinds of Garrett GT15 listed so the easyest thing to do is drop it off and see what they say.

Oh and to add to that on removing bumper the Abarth fog lamp was cracked and it wasn't when i headed off that morning so happened on the way so need to follow up my hunch that Abarth lamps are in fact Ford Fiesta Si roughly M reg lamps as mine have Ford badges on the electrical connector and I walk past a Fiesta Si M reg everyday at work and sure lamps are the same.

You seem to be in easy reach of this never ending motorsport type tuning places Aaron you jammy c**t! LOL

That's a bummer, any ideas on the cause? Surely not a general thing for all turbos is it?

Well if its cracking, Id wanna think its gonna be something to do with creep on the turbo housing.

It wouldnt be totally unbelieveable, as theres a stress at temperature over a long time, and to compound problems the stress and temperatures cycle!!

Only real way to prevent it is to make the point under as little stress as possible, and make it as cool as feasibly possible! But I can see how that would happen in any installation, but I should imagine the Cinq / Sei is particularly bad given the heat in the engine bay - theres a lot in a small space!!

nice shiny new, bigger one :D

Spoke with Turbo Technics today, can drop off turbo and see if salvageable, but I know its not, its well and truly fecked, so looks like new turbo time which is expensive, like £500 expensive especially as the turbo I have is a Garrett T15 made in France code 454092-1 which relates to no other turbo i can find, closest was a 454091-1 on some Citroen Zantia 2.1 diesel. Doesn't help that the T15 is an old turbo now superseded by the GT15 and is not close to the turbo's off VW/Audi group turbo diesels that others have offered as where they come from.

So do i just get a new turbo albeit a newer GT series turbo, or do i get a new manifold made up with a better 4 bolt configuration and fit something a bit better like a GT17 turbo or even a T2 as fitted to R5GTT's as these are much easier and cheaper to source and produce more power from less boost.

just need to see what route i take, either fix it or destroy it by throwing ot off a cliff and buying a decent hot hatch from a French manufacturer :p
 
Van Aaken must have used a variety of different turbos. Mine's engraved on the housing with a VW logo! Had a look at the pics of Emz' car too, the zorst is different from mine as well.

Definitely the snowflake effect!
 
aaron, i've left alexs old cracked turbo manifold with a local place today to see what they make of it. if they can fix that, il ask them to make me a manifold to hold my K03 turbo. Im sure it wont cost much more to weld a differnt flange on to take a different turbo.
or just get a custom stainless one done, powerflow place in stafford quoted me around £150 for that.

re stuff from french manufacturers.. i worked on an AX today :yuck: then my cinq punished me for it by understeering into a kerb and destroying one of my wheels :(

thought you may have liked that last comment.

Mmmm dreams of MK1 106 Rallyes with hand built 1.3L homologation engines and taught chassis to die for, or MK1 16V Clios, maybe even a Williams, something cheapish to preserve the 'grale, lol
should have got that mint 5 GT of ebay couple of weeks ago.£3k,FSH and totally standard :eek:

I've had two tho, a black one and a grey one, as much as I love them after two you need to move on, tho a mint one with FSH is a good find.

A R5GTT is only 100kgs heavier than a Cinq, and 180-200bhp is not a difficult figure to get to as well realiably.

Mmmm interesting, £150 is a decent price for a s/s manifold as it's pretty small. How good is this place tho at making manifolds, did they have any examples of there work there? i would be well tempted to get one as my manifold has suffered from internal melting (i kid you not) so although usable with no side effects would be nice to get a s/s one. This was probably due to wastegate sticking as crack goes right through were it is internally and over heating.
 
ive not seen any examples of the guys work, but ive chatted to him a few times before now and sees to actually care about his work. its only him that works there it seems, and he takes pride in all the stuff he does.

it was spyke off here that put me in touch him - he'd done a manifold and some other work for a mate of his, and it was all top notch (ive not seen it myself though)

How close is he to you and can you get a confirmed price on a manifold made up but with a garrett T2 fitting which is a four bolt fitting rather than 3 bolt that is on my manifold now?

Aaron.
