Hi guys,

I'm out here in Australia and my radiator on my Series 2 decided to have a good cry all over the driveway (rather there than in the city), so while it was all taken apart at the front I thought I would give the turbo a little wiggle to test for play in the shaft and it is rooted, so I jumped on turborebuild.co.uk to organise a replacement cartridge and they recommend measuring the impeller to be sure that their cartridge will fit. Their replacement has a measurement of 40.5mm side to side on the photo on their website but after measuring mine it is only 38.5 which means (obviously) their replacement cartridge won't fit into my turbo housing. I looked back through the receipts for the car and sure enough theres a receipt for a TB0355 which should be the turbo to match 40.5mm shouldn't it? So I don't know what to do for the best now, buy a proper sized (but used and knackered) turbo and rebuild it to have the correct turbo or rebuild what I have and keep using it?

Any advice would be gratefully received!

Craig.

What are your goals mate?
If it's tuned for what you have then you could just get yours rebuilt, or maybe take the opportunity to go for more power? Plenty of options if you have a decent RST tuner over there to set it up?

Hi Karlos - thanks for your reply,

On the turbo rebuild website they do a standard cartridge and a 'stage 1' also, I wanted to go with the stage 1 as just a small upgrade as I have a 2 1/2" straight through pipe and the car is on standalone management - it's a weird setup, the previous owner pulled all the k-jetronic equipment out and had an efi system custom made for the car. Due to the fact that European RS's are as rare as hen's teeth out here they used parts from a Nissan RB20 (AFM etc etc) to make the whole thing work, which it does pretty well. At the last dyno tune it pulled 169 bhp which is not bad for an engine I'm fairly sure is standard except for an exhaust and air filter.

My goals are to just get her up and running again as she's my daily driver and obviously work out why the turbo seems to be smaller than standard, then decide whether to buy a used one in need of repair off someone to get the correct size or to try and get this 'smaller' one rebuilt, or third option buy a new turbo but I would have no idea what I need to look for to compare like for like for garrett or any other turbo manufacturer, so I would need help from someone in the know.

Thanks mate

Craig.

Ok Craig well the EFi system really helps you out here, if there's someone that can map it and your engine is in good health then the normal route would be a stage 2 T3 (.36/50), an uprated clutch and intercooler and you could make over 200bhp.
I'm sure there must be someone over there that can supply you a recon T3, if not shipping a whole turbo from the UK really isn't that much money either.
There's a guy on here username Wilky that does turbo rebuilds and he's very helpful, might be worth dropping him a PM, or if you're on Facebook here's a link to his page: I'm assuming your on the standard exhaust manifold of course?
