If the goal is mid 11's then you won't really need any more than 280rwkw on a tune that is focused on a wide power band. On a stock motor the less rpm / boost and power you need to throw it at the better, it just makes the odds of the un thinkable that much lower. Think of it as more peice of mind when you ring it's neck, makes things more fun.

Lets not forget good tyres.

* The smaller frame SS/ -7's would do the job being capable of over 300rwkw.

* A set of tomei cams, adjustable cam gear. Some extra dyno time to set cam timing to bring the power curve down. Lop off the top end peak as a trade for mid range.

* Full exhaust

Then I would be spending a few bucks on response mods, these are not 'power gaining' although these increase accelleration;

* lightweight rims

* lightweight flywheel /clutch assembly

* Carbonfibre tail shaft

* Lightweight ATI/Ross balancer

* Electric thermo fan

* Greddy pully kit

carbonfibre tailshaft?? now your just getting a little far ahead of yourself!

no need to waste money on thermos, and lighter pulleys for tiny power gains... he is just after a qik daily street car not a race car.

Those mods on the plan should see him into the mid 11's easily.

qikgtr how many kw did your car have when you went to the drags the other day ?

I'm not 100% sure on wheather or not the KW figure the car had been sold to me with was AWKW or RWKW, it was stated that it had 206AWKW, but the shop that did the tuning has a RWD dyno only, so I'm not sure anymore...my guess would be that it is AWKW because 206RWKW would equate to 180ishRWKW and it would have more than that I'm sure.

Rev210, thanks for the input, got the clutch and lightweight rims already, certainly agree with you that I don't want to push the motor beyond what it needs to be pushed to gain me my 11....so if I only need 280 or so KW then so be it, but I am lead to believe I need at least 300 for mid 11s. I'm not going to rape the engine if I don't need to, but I also agree that the easier the engine makes the power and on lesser boost the better!

Glenn, you've got it pretty much right with what I want and I'll follow your recommendations for changing pumps etc too as I want to replace everything that may need replacing on a 10yr old car for safety sake.....not after things like CF tailshafts though :rofl:

Rev's guide is basically what I said in my initial list anyway, plus a fuel system upgrade of course! I'll stay away from some of the stuff on his added list though.

I don't want a mountain of power, I guess the 330-350 guide was a bit unnecessary, I'm more after a time than a power figure(as a power figure is dyno dependant anyway).....so if a milder setup on 16-18psi will get me an 11....then the safer and lower the pressure on the motor, the better!

I think I can drive, but most people probably think they can, depends what you define by "can drive" I suppose?!?!?

But a good set of semi's on some stockos will be a good idea....or even on my Volks!

They aren't a waste of money actually.

You basically gain no power at all with intertia reduction, you do gain very substancial accelleration however and in the case of lightweight rims better handling and stopping abillity.

If you want to inform yourself better about lightwieght tailshafts for GTR's , particularly for drag racing (as mr centre bearing gets quite upset on launches), then there are a few guys on the forum who can clue you in on whether they are a waste of money. Justinfox has one from memory.

If money is your hang up (better sell your GTR if it is - joke) just for you there is a cheap'o option with the single peice tailshaft offered by UAS, $495 exchange and drops 5.5kg's off the weight.

The response gained by dropping the weight from these items makes the car more enjoyable to drive and doesn't add to wear like extra horsepower so it's hardly a waste on a road car.

      Duncan's V37.......race car?

      By soviet_merlin · Posted

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
