What turbos from other cars fit the C1J as a straight bolt on?

[Woznaldo]

As per the title, what turbos from other cars bolt straight up and which need some minor mods?

The names that people most talk about are:

Rover 220 coupe turbo - Tomcat
Nissan S14 0.49 turbine housing
Saab 9000

Any others please shout out

Japanese cars are easier for me but interested to hear about anything for everyone's sake.

Think the variant you want is the N1 turbo with steel internals
Pretty good turbos roller ball bearings T25/t28 size small ar comp housing maybe small Ar turbine housing too, been a while since I researched them tho

This is why I have started this thread, to lock in some facts that people can refer to.

Fiat coupe turbo, can be used on the F7P and Volvo but not sure if too large for the C1J

Here is the std C1J T2 Turbine Housing rear end to compare.

Here's the std GT-R turbos.



looks good except no top bolt on the T2?

I notice a lot of other turbos are not water cooled. What are people doing here? Just joining the cooling hoses together?

Are you currently running a standard coolant setup? If so then yes you could just join them together. But you can make it look neater.

I am going to be running a very minimal coolant setup.
Using an oil cooled vnt and removing the degassing chamber also.
So I will be blocking the return (to waterpump)from turbo with a short discreet hose and bolt.
Water pump outlet to inlet manifold has a bung fitted - so no cooling/heating to inlet or carb either.
