2004年9月27日 · There's another way to check if your car have the VTC. We had both engines @ Mexico & at least here the main difference is the form of the intake & the position of the Air Filter: Air Filter Box behind the Battery, & throttle body vertical, aside of the engine, it's a …

2002年11月15日 · (these are off the top of my head) 3400, 5000, and 6700. at 3400, VTC retards timing, b/c @ lower RPM, you dont need highly-advanced timing. at 5000, VTC advances timing, b/c @ higher RPM, the engine is moving so fast, that advancing ignition helps in getting a complete burn. @ 6700, VTC retards again, so that it degrades power slightly (ga16 ...

2004年8月23日 · sorry for taking long to reply guys, hardly get time to log on these days. so before you guys think i'm b.s. you, the last time I dynoed my car was a year ago and i was making 280hp at the wheels, all I did since then was change my turbo to a custom made larger one (t3 hybred) and have not dynoed since, but i'm damm sure its well over 300 at the wheels, like i said I dynoed over a year ago so ...

2005年7月6日 · hey zellx. i read in a sport compact car a few years ago that the s13 sr20 had a high-port head and straighter intake runners and that these engines had more power potential than the later, s14 sr20 that had low-port heads and vtc. as for the swap, the s14 obviously has more stock power so unless youre doing some modding, youre better off with the s14, (blacktop), especially since the swap is ...

2012年2月5日 · I have been running the car for about 3 months since the swap and ever since I have had a loud sucking noise coming somewhere from the intake manifold. I was assuming that I had an air leak somewhere because I would sometimes get erratic idling or the engine would "race" while driving. Consequently I have had terrible gas mileage because of this.

2002年6月1日 · The VTC-equipped GA16DE produces 120 hp (85 kW) @ 6400 rpms while the European-spec non-VTC GA16DE produces 102 hp (76 kW) @ 6400 rpms. That right there should tell you not all GA16DE comes with VTC. As well, the GA16DNE (DOHC TBFI) also does not have VTC, and produces 105 hp (78 kW) @ 6400 rpms.

2004年9月1日 · Also, I think you can upgrade the internals to a GA15, but not to a GA16 as that has a bigger bore. Or I think you can just install VTC head. Definitely get a 4-2-1 header and turn your intake into a CAI. I won't install a VTC head on my car, but I believe I can get 120-125hp with the I/E/T mods I mentioned above (stock is 105hp).

2002年9月18日 · I have the VG30DE in my 90 Z, and had a tapping sound up front, driver's side. It turned out to be a weak VTC spring (inside the intake cam sprocket on the driver's side in my car). I got a new spring and O-ring seal for $4 from the dealer and changed them in half an hour and no more noise. That may be the case in your car.

2014年5月26日 · So i decided to replace the lower TC stuff since rattle is still present even after replacing upper tensioner. So far i have everything removed (except head) as per updated procedure from Nissan. I've checked, double, and triple checked that all bolts / fasteners are removed, even the 10mm top bolt under the VTC solenoid (was that a PITA to get ...

2009年7月21日 · Hi Guys my name is PFB, I'm the proud owner of two Nissan products one being a GA16DE powered sentra. In South Africa we received the GA16DE and the GA16DNE both didn't have VTC. I have done the basic modifications to my GA16DE CAI Tri-Y header 2.25 Inch Exhaust 272 Billet Cams Grounding kit...
