Any suggestions please for my coupe for approx 250- 300bhp with a decat thanks

Just get the standard one hybrid that way you get great spool and power

http://pages.ebay.com/link/?nav=item.view&alt=web&id=261625531019

Easy 270-290 bhp with minimal extra lag...

Mods needed to get best out of this would be

fmic
Larger down pipe
3 bar for
Live map (max boost 1.3-1.4 bar)

Just check with these cossie turbos that you get a .48ar exhaust housing as for you bhp goal a larger .63ar will make the engine considerably less responsive!

Bang on the money!

Don't forget a 1.2 bar wastegate actuator (fit it using your old Coupe wastegate bracket).

Is this turbo ok ? With decat ? Is it true it damages turbo seals I'm still running stock turbo at moment with decat pipe ?

The 250-300bhp goal is quite a separation, the lower to middle end requires less investment. Is there anything wrong with your current turbo?

No mate it's all good at moment no smoke ect done 50k though

Also I think my fuel pump is on its way out I was going to buy a walbro 255 are these universal ? There's loads on ebay cheers folks

as Gillian said you can biuld your own hybrid turbo
using larger compressor wheel for sale in ebay
working your turbo and refurbing with the one of the kits
sold in the bay, then a larger free flow exhaust and a fmic
with a decent map will complete the upgrade

bear in mind that the oem exhaust is cohibented
thereby just opening and removing the inside
will work like a bigger exhaust, you need only to cover
with insulating fibreglass to avoid overheating the oil sump

you have only to buy an aftermarket bend (3inch) for the first part
of downpipe where is placed the lambda

Decats and leaking oil seals only applies to 20VTs and their T28 turbos. T3s are fine.




I've built a few custom hybrid turbos for myself and customers in the past and can tell you building a hybrid turbo isn't even close to being that easy! non-standard compressors don't just fit inside the stock housings. The housing has to be machined to fit. On rare occasions it's possible to buy a wheel and cover combo, but there are still other issues to consider; The rotating assembly has to be balanced. Also, the wastegate actuator usually has to be modified and relocated, involving more custom machining and welding.

Not to put off anyone who wants to try building their own for the challenge, but just be aware it's not just bolt on and drive off!

yes of course it needs prof machining the compressor housing
far less expensive than buy a new turbo garrett
but you can consider Turbonetics one

I was going to say I don't think it's that easy to do

Hi, tried to pm you but your box is full..

Not now

I agree with this.My short story about 16VT's.

My old original turbo was doing fine at 80,000 miles but, in the quest for more power i stripped it to build a hybrid with a larger compressor housing, change of bearings etc etc. I also built a spare hybrid using different ratios and swapped them in and out. The car ran ok but had alot of niggles, machine shop small costs (that added up) and in the end just took one of the units to turbotechnics and got one of their Custom Integrale hybrids, it worked out to be not that much more expensive than the units i had built and is far better quality. These guys do it for a living.

My units, whilst cobbled together from ebay bits, did last a few 1000 miles, a couple of trips to the nurburgring etc. But if I had to do it all again, i would go straight for an exchange unit, be it an off the shelf hybrid or something custom built
