I guess it all comes down to personal preference.

I paid ~$1500 all up for my exhaust system. The extractors were $440, with $250 HPC plus another ~$250 for postage and labour. The other $500 went into the high flow cat and cannon.

When I did it I thought "great, an extra 20rwkw (plus the low end power) on my NA Supra is just what I need", spent all the money and was... unimpressed. I don't want people to make the same mistake. It's definitely there, and you can feel it, but its nothing amazing.

when i did the pulsar i did the catback and didn't notice much. then a month or so later did the extractors and it made a massive difference. not much down low but above 5000rpm was totally different. pulled hard all the way to 7500 instead of starting to choke at 5500rpm. all up the system cost me about $650. left the stock cat cause it was 2.5". then another guy in town with a SSS who still had the stock headers took ot for a drive to see if it was worthwhile getting some and was very impressed with the difference it made.

then when i got the magna i did the catback first. made a noticable difference. then did the extractors and it didn't really make any difference. so when i got my second magna i didn't bother putting extractors on there. and from reading on the magna forums most people agree. they say that there is no point putting on extractors unless you have put in bigger cams. and when you look at the times people have run there is little difference between those with extractors and those without, yet if you look at the pulsars there is a bit of a difference.

Personally, i'd be stoked if i paid $1500 for 20rwkw gain!

I have paid $1200 to gain 6rwkw, and given the chance, i'd do it again. It's not all just the peak power too...the response, power curve/average, power delivery and knocking/detonation all counts too when you do a mod. At least that's how i look at it.

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      Did you panel beat the dents or have you tried to repair this only using filler?  Is your sanding block soft/flexible and is following the shape of the panel rather then just knocking down the high points?

      I haven't knocked them down yet. I think I made the repair more complex than it should have been. I had rock chips combined with waviness and dents and I tackled it all in one because it was near each other and just end up wasting a bunch of bog lol. I'll knock down those areas and see how I go. And yep what you are saying at the end is correct. I think I might be sanding the top of a steep hill then my sanding block falls into the dent and gets rid of the guidecoat if that makes sense. Though shouldnt unless I'm covering too big of an area with not a long enough block. I'll try something new and provide some updates. Getting there though! Thanks as always.

      Yeah makes sense, hard to comment on your situation without seeing what your doing. I was talking generally before, I would not be looking to randomly create low spots with a hammer to then have to fill them.  It's hard without seeing what your doing, it sounds like you are using the guide coat to identify low spots, as you're saying the panel is still wavy. I don't see how you're not ending up with patches of guide coat remaining in a wavy panel? Once the high spots are knocked down to the correct level, surely to have a wavy panel you need low spots. And those low spots would have guide coat still in them?

      So I'll put filler past the repair area a bit to make sure I don't miss anything. Then I'll block it until it's almost level, put the guidecoat, then keep blocking until it's gone. Then it's still wavy.  In regards to hitting the panel, I saw this video might give more context - Skip to 0:47 he knocks it down. But yeah I'm sanding until the guidecoat is gone then checking because otherwise my filler is still well above the bodyline. Unless what you're saying is I should put guidecoat around it early, surrounding the filler then stip once it's gone?

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.
