Hi guys, some interesting fact and questions here!
I'm from Holland, and bought myself (after driving a Nissan Micra/March 1.3 CG13DE for one year.....) another car. It's a P10 Primera powered by a low-port SR20De. Here in Holland you can buy these Primera's with a SR20De and the SR20DE engine. The difference is the "e" has 125 hp and the "E" has 143 hp.
Also the "E" engine is a high port.
There is a differende also between these two engines in CR! The low-port has 9,5:1 vs 10:1 on the high-port.
I've HAD a SR20De RR engine too, and put some JWT S3R cams in. The original power I had was only 132 HP, but with these cams I got to 173 HP 210 Nm!!
Now here's my thing...... I ordered some S3 cams at JWT, and Ben Pila told me the power I would gain should be around 15 HP. I truely think that I will gain MUCH more if I put these S3 cams inside my (standard 125 hp) low-port SR20De.
I believe the power I will gain should be the same as I had with the S3R cams inside the SR20 RR engine.
There is nobody who can give me a straight answer on this question....
*the 174 hp was also because I put a complete 2,5 stainless exhaust system under the car, and a modified intake, with a custom made TB 64mm. But these mods will also come on the P10 I have now.
