FRANCO-NISMO · Jul 5th, 2003, 02:27 AM

I have 2 CA engines: CA18de and CA18DET (first generation).
i´m rebuilting now my turbo engine, but now i want to make some upgrades.
i bought a MINE´S ECU, stock turbo T25, ligthness flywheel,HKS intercooler, HKS BOV...
But i read here the CA18DE cams is a mild upgrade to CA18DET.
the head block of the CA18DE and CA18DET are different in the combustion camera area. The DE camera is little close tham the DET, the DE intake valves are more big tham the DET.

So i want to make a full head port, but i don´t know wich head port, DE head or DET head?

i just want more air flow into the cylinder to gain more power...

please help me...

and if you can give me some advice to perform more my engine, please tell me....

I would go with the DE's head and intake manifold. These are different than the first GEN CA18DET engine and combustions areas aren't really that different. Although the 1st gen's set-up is not that bad, it has too many individual runners for maintenance sake. What kind of lightened flywheel do you have or did you have someone shave the existing flywheel because the RWD's flywheel is too big for the FWD bellhousing.
