TD04 mods
Hi everybody, I've searched the forum and I cant find the information I am looking for. I own a 2001 Volvo C70 convertible with a turbocharged 5 cylinder engine and a automatic transmission
It is the low pressure model that has a 2.4 liter engine, the high pressure has a 2.3 liter. The 2.4 has a slightly higher compression ration of about 9.5.1 compared to 9.0.1
The low pressure turbo has a TD04HL13G, its a small turbo. The engine is tuned from the factory to fell like a strong V6, it has a nice smooth power band.
Now to my problem
I've been doing my research and it indicates I shouldn't use a 19T because of boost spikes that can bend rods.
So I want to run a 18T, I've seen kits on ebay that I can use to turn the 13G into a 19T by changing the cool-side compressor housing, compressor wheel & waste-gate actuator
I've also read that I can get a 16T and then have the cool-side machined so that a 18T compressor wheel can be installed.
I searched some for a 16T to use as my base for the project but I was wondering if anybody knew if I could have my 13G compressor housing machined for a 16T to 18T compressor wheel?
Sorry for writing a short book but I figured I should provide some info.
Thanks for the advice

conclusion
I emailed a turbo supplier on ebay that had a aftermarket 18T turbine compressor wheel that fits a Mitsubishi Heavy Industries TD04HL turbo and asked if it would fit in my compressor housing if it was machined and they said yes the compressor housing will need machined.
My concern is that the compressor housing will be thinner and that could lead to stress cracks. I was thinking maybe I could paint the housing with carbine-fiber resin and then lay some sheets of carbine-fiber & more resin over it to add some extra support.
As you know the cool-side of the turbo doesn't get as hot and carbine-fiber can withstand high temperatures so I think it could add some support & be ok in that environment

I contacted a turbo supplier on ebay that sells 18T compressor turbine wheels and asked if they sold the 18T compressor housing so that I didn't have to get mine machined but they don't carry them.
I asked if he know if the compressor housing would be weaker after it was machined and he didn't know and said I should talk to a machinist.
I've been thinking about my idea to try and reenforce the compressor housing with carbon-fiber and I think that even thought resin adherers well it might release from the compressor casting and then add no extra strength to the housing. I was thinking maybe I could make the carbon fiber part as planned but put some release agent on the housing so it re-leases the carbon-fiber and then use some metal epoxy {the good stuff thou-- and put a coat of that on the compressor housing and then install the carbon-fiber part and press the housing, metal epoxy and carbon-fiber cover tougher. Just a thought? The casting might be strong after machining, I need to talk to a machinist.
