What turbos can I bolt onto the standard CA18DET exhaust manifold for more power?
For a cheap solution your best bet would be a T28 off an S14 Silvia/200SX. While these are non-ballbearing turbos, they are quite a bit bigger than the standard T25 on the CA18. Expect to pay $400 up to about $600 for one of these. Another cheap alternative is a T25g from an S13 Silvia, these are a bit smaller but would still be a decent upgrade and are readily available due to all the S13 owners upgrading to bb T28’s! If you have a bit more to spend you could try and get hold of a ballbearing T28 off an S15 Silvia/200SX, they go for around $1000 but are sometimes difficult to find due to their newness. Another idea if you have the money is basically any other GT28/GT25 turbo that advertises as being a bolt on job to either a SR20 or CA18 exhaust manifold. Please note that ‘bolt on’ (a misleading term really) mostly does not mean that you can just replace the turbo and bolt everything up and drive away, is most cases you will need to do some type of stuffing around to get it all workin
