 |
|
I'm going to look at what a guy claims is a CDT Head this weekend - can anyone tell me what to look for? What's the difference between a CDT Head and a normal large valve head??
Part 2. How much better are they performance wise?? |

| The CDT S3 (turbo) heads had over 100 man hours spent on them with attention paid to gas flow, blueprinting and matching the manifolds. |

| That's good but how will I know to look at it? He's running a Rajay turbo (no external wastegate) but with a decent size turbo on top a 1800 block (bored to 2.0 ltr)??? Anything could happen. |

| unless you want to measure everything up you wont know if its been modified but still, you could do a bit of port work to any head and say it was off a cdt. Unfortunatly the heads didnt come with a big CDT stamped into tem and there were a very limited number of them so either its good or the guys full of shit. Running a 1600 head on a 2ltr bottom end will also require some serious decomp pistons for a turbo motor. |
