Anyone tell me what the cheapest options are for repairing leaky turbo seals?

I hear that I might as well get the turbos re-done or replaced at the same time and I was wondering what the options might be without spending a fortune.

 

All helpful suggestions welcome.

Nige, 2 areas that restrict power on the Zed are the stock turbo pipes as explained the turbulence above and the stock manifolds due to their design, by using the dump pipes it is helped in gaining more power from the turbo's and an even quicker spool up time as the turbulence can cause the opposite effect, so in this case, nowt really specila as regards back pressure and dump pipes but gets things really smoothhhh.

ok, Do I need to account for some special dump pipes in my costing? - do you supply these with the turbos?

 

and what is the availability on all of this kit?

 

and (finally esther!) can you tell me what boost pressures people are running with the stage 1 tubs?

Dump pipes are simply your choice mate, if you want more from turbos, these will do it, so only buy if a) that's what you want and b) yer have the cash. Yep i supply them just look in my traders section. 1 point though on them, in order to achieve the best possible gain they designed to the same length as a series 2 Zed stock turbo pipes, if your series 1, pre sept 1992, thenm you need to shorten your existing down pipes, very easy to do, any gargae worth their salt in about 40 mins, i can help with that explanation to them if needed. This is for any make size of turbo BTW.

If you decide on the roller bearing turbo's and NOT the dump pipes, as they are larger than stock, new turbo pipes are required anyways, i can supply these for about 180 quid, if stage ones are bought, then no need to alter down pipes at all UNLESS you decide to have dump pipes. Geez hope that explains it mate.

Availability is good, turbo's take approx 3 days after cleared funds to me and dump pipes 8 days.

As for boost, many i know have in fact lowered the boost pressure when going with hybrids as it actually gives same power, (cos their using uprated tubs) some go up, i was running 18psi on mine, but boost is dependant on correct fuelling and mixture etc, so you don't need to go high boost to make the power is what am trying to say.

I can tell you know what you're talking about, but I'm struggling to keep up here. I had a look on your web site, but didn't find the dump pipes (!)

 

I can't justify the expense of Stage 2's at the moment, so I'm confident that it will have to be stage 1's. My car is a 1991 Jap import. I'm sure my garage can shorten the pipes if required, but if they've run up a huge bill getting to fit the new tubs, would it not be in my best interest to get the dump pipes? - and if so, is that the £180 you mention??

Ta muchly for the help!

ah, just found the info trawling through the traders forum - you need to add these to your list of products!

 

It mentions 4 bolt and 5 bolt varieties, which do I need and, if I get these, do they replace the stock pipes (so I don't need to shorten them?)

 

(Just noticed that there's only £745 difference between the stage 1 and stage 2 tubs and I can see my potential bill getting BIGGER by the minute!)

Hi mate, stage 1 tubs on their own need no mods done to anything, stage 2 tubs cos are bigger need new TURBO pipes fabricated which are very much shorter, these ones i can do. IF you have the DUMP pipes as advertised in my traders section with ANY of the turbos you need to shorten the DOWN PIPES these connect onto your turbo pipes see and would be too long, this job the garage can very easily do. I advise the customer when buying dump pipes which ones he needs, 5 bolt or 4 bolt, though it does list it already, in the case of my turbo's the stage 1 are 4 bolt and the stage 2 are 5 bolt. Hows that fella ? finally even though i've not advertised it, any one having stage 2 turbos and DUMP pipes i'll cover the cost of new braided oil feeds to suit normally 75 quid as obviously when changing tubs you fit new oil feeds, rather than using nissan ones i throw in something better.

OK, it is complicated for someone with a tired brain.

I think I'm getting my head around it slowly, but perhaps you could give me the breakdown in a simplified format?

 

Option 1 - stage 1 Turbos

(cost of new turbos and labour)

Option 1 a - stage 1 Turbos and 4 bolt dump pipes - needs the stock down pipes shortening

Option 2 - stage 2 Turbos + new turbo pipes (what do these cost?) + labour (anything else I need to include?)

Option 2 a - stage 2 turbos and 5 bolt dump pipes (do these still need new turbo pipes or do the dump pipes replace them?)

I was considering that i might need new turbos soon!! After reading all of this im well confused and completly lost!!!

 

Fas

I am now and i bloody typed it :rofl:

option 1, stage 1 turbos at 1175, Labour depends on where you go but at around 700 quid, no mods requierd for ANYTHING

option 1a, stage 1 turbo's AND Greg dupree dump pipes cost as above PLUS 370 quid for the turbo pipes, the DOWN pipes require modification to suit the dump pipes if your series 1 and i estimate that cost to be 30 quid ish

Option 2, stage 2 roller bearing turbo's cost 1920, being larger require a shorter TURBO pipe, which i can do for around 180 a pair, NO modifications to DOWN pipes, labour is same as above.

Otion 2a, roller bearing turbo's with Greg dupree 5 bolt dump pipes, cost as above for turbo's plus 390 for DUMP pipes (in stainless) modification required to DOWN pipes to make them shorter, estimate is same as above for this. Also at this stage i throw in 75 quids worth of braided oil feed hoses for FREE.

So in short, you ONLY make modifications to DOWN pipes IF you decide to use the Greg dupree dump pipes, if you don't use em, then no mods required.

Your a gentleman for taking the time to explain this and I think your last email should go into the FAQ section for being so completely clear and understandable.

 

Now I just need to speak to my mechanic and decide how much money I can throw at it!

 

Thanks again, I'll be back!
