Would this fit my Coupe ?

I'm after a better powerful turbo

These are cheap crap I take it

Am I right in thinking a rs cosworth t3 will give me power gains ?

The spec is - meh "okay". I don't think 350 bhp would squeeze through that little hot-side though - more like 300 - if that. The biggest problem with those "chinaturbos" is the quality control - or lack of it. It may last for a while or it may not. Pot luck.

Probably fair to say I've gone through a wider variety of 16VT turbochargers and engine setups than anyone in this forum Plus built a few bespoke hybrid turbos for myself and customers in the past. So if you tell me your current engine mods and power goals I can advise you of a much better turbo, plus supporting mods to match.

The picture does not match the description. Turbo looks like a std T3 with a .42 comp cover which is normal for them. It's hard to know what you'll even get.

Nothing special more or less standard , fmic , dump valve ,induction kit , a flea chip boost pressure raised to 1.1 bar running standard ebv I'd saying running 220-230ish oh and standard t3 turbo I'm looking for another 50bhp 280ish mark would be good how do I go on about the straight induction mod ? My induction kit is in same place as the standard air box I know roughy but what about dump valve which comes from the standard pipe work ?

More like 220 bhp with your current mods.

Easiest way to 280 bhp: T3 60-trim turbo, larger injectors, custom 2.5" downpipe, and a decent live-map from a 16VT specialist.

The stock routing of the induction pipework is perfectly adequate for 280 bhp, I was making well over 400 bhp by the time I moved from the stock air filter location - and those was just for issues of space. In fact I'd even recommend using the stock airbox with a panel performance panel filter over an induction kit. But not a big deal if you don't still have it.

There are few different options for turbochargers and downpipes, depending on your intended use and plans for the future. I'll PM you later on with more details.

Great

Mines running around 330 with one of those turbos, though when my oil seals went I had it fully rebuilt by turbo technics (which cost a hell of a lot more than I imagine the original owner payed for the turb0 in the first place!). I do have fuelling upgrades as well as most of the bits you mentioned
