Jwink25 Posted June 10, 2003 Share Posted June 10, 2003 I tore apart my intake to clean it all up and had been thinking about porting it while it is off the engine. I have never ported an intake before and have a few questions. 1. Being a turbo engine...would a mild port job be of any real benifit? I am upgrading the turbo and will be running a 3" DP. 2. I can see where the old gasket ended and where the extra metal is...should I buy a new gasket first, to make sure, it fits the same way? 3. Do I need to tapper it back into the intake? Start out getting all the extra metal up front, and then just tapper it back, as far as, I can go? 4. With the bits I bought, I can only go in about 3 maybe 4 inches...is this enough? Any other tips or thoughts to add to this? Thanks, Jason Quote Link to comment Share on other sites More sharing options...
Jwink25 Posted June 10, 2003 Author Share Posted June 10, 2003 One more thing, at the very top of the intake port opening, where the fuel flows in from the injectors, is it ok to grind some of that away. It won't mess up the fuel spray patteren or something? Just wondering. Jason Quote Link to comment Share on other sites More sharing options...
Kazuya1274 Posted June 11, 2003 Share Posted June 11, 2003 I have the old How to modify your Nissan/Datsun engine, and it has a section on head porting. I'm in Pittsburg, KS have you ever taken your car out to MOKAN? What color is your car? I'm in Joplin all the time, maybe we can meet up sometime.

Lockjaw Posted June 11, 2003 Share Posted June 11, 2003 Are you talking about porting the intake manifold? If so, match it to the gasket(s). You just want to make the transitions smooth. Quote Link to comment Share on other sites More sharing options...
Jwink25 Posted June 11, 2003 Author Share Posted June 11, 2003 Just match the gaskets and then tapper it back as far as I can each? Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted June 11, 2003 Share Posted June 11, 2003 On what, the throttle body or the intake runners? On the tb, just go in until it opens up, on the runners, I wouldn't worry about going in more then an inch or so. Quote Link to comment Share on other sites More sharing options...
Jwink25 Posted June 11, 2003 Author Share Posted June 11, 2003 Yeah, on the intake runners, I'll do the throttle body as well. I'll just wait until I get my 240SX TB. Jason Quote Link to comment Share on other sites More sharing options...
