Turbo options????????????
I am in the middle of doing the head gaskets on my scooby and have noticed the inlet blades on the turbo look worn
It's a V2 car but im running a small front entry hybrid IHI turbo.
My question is this if I put a bigger turbo on it am I going to get clearence issues with the manifold, at the moment i have a 90 degree samco hose connecting the turbo to the main inlet pipe and it's avery tight fit
The car is running about 320/320 and it spools up very quickly, I dont want to go backwards in terms of spool and max power but an early tdo5 would solve my inlet hose problem but would it be a big difference in spool?
At the moment it makes a small amount of positive boost at 2.5k and 1 bar at 3k and max at 3.2-3.3k then holds it until 6.5k then it tails off to less than a bar at 8k
i would like to get everyones opinion on this while the car is in bit's!
Thanks

James, if the bigger turbo has the same inlet size you shouldn't get a clearance issue. Also can I suggest a small hijack here? I think it would be nice if we had a list of turbos and what their boost threshold is?
My experiences are on 2l engines
TD05: Full boost at about 3500rpm
VF11:Positive manifold pressure at 2000rpm, full boost at 2800rpm
Any other takers?

hi mate the IHI serial number has been ground away because it's a hybrid, having had a good look at it I think it would have been a VF22/23 before it was modified with different compressor wheels etc.
I was thinking about putting a VF28 on or maybe a standard VF22/23 but I was worried about the inlet on the front sticking out further than it does already due to the clearence issues with the inlet hose.
I was considering raising the manifold as well but from what I can gather it's not as simple as just fitting the spacers, I think I have to relocate the power steering bit's and pieces!
What was a straight forward head hasket job is turning into a bit of a nightmare!!
Having said that I want to get the car right so Im going to take my time and do it right first time!
