I looked in to this when i first bought my 34GT . From memory, simply put - by replacing your exhaust side cam gear with the GTT or aftermarket one, you can acheive a good power gain. Not 100% on the settings as to retard or advance it, depends on the driver's preferences really. Look forward to hearing from more people's experiences...I never went ahead with mine, still got the cam gear sitting on my desk!

They should be fine. Again, to retain your VCT, you should leave the intake cam gear untouched and replace only the exhaust side. I havn't had enough experience with them to recommend anything, but I'm sure there's someone in the N/A section who can clarify.

Tomei pon cams to suit the neo head will drop into the NA neo head. These cams are designed to retain VCT so you only put an adjustable gear on the exhaust side for tuning.

The stock cams between the turbo and na neo heads have the same duration and lift (according to tomei), so if you mean switching to "turbo cams", make sure they are aftermarket neo cams.

They'll fit but they are less aggressive than the NA cams so very little point.

Usually the reverse is done, people usually fit the NA cams into turbo motor

that is what i thought. i know that guys with turbo SR20s often put in the NA cams as a cheap, basic upgrade

      The final part arrived today to un-clampify and simplify the intake Who would have though a 1/2" hose stainless bulkhead fitting designed for below waterline bilge pumps would be what I needed Test fit on a 3" offcut I had laying around to see if it would work, and it worked a treat All going well the intake will be on its "final version" tomorrow

      Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
