  1. Haha the old garden hose theory!

    Basically by the time you engineered a turbo with bigger wheels to fit inside a gt35 you could have paid for a manifold etc and had a proper setup. This is without even considering that once you did squeeze the bigger internals into the gt35 that the housing and stock manifold would become so much of a restriction that it would basically negate any gains that you would see. The end result would be lots of lag with not much power increase and you would be a very disapointed camper.

    My back to back testing on only 10 psi showed that the stock manifold is costing 12% power as it is, the more power you make the more power it will cost you so trying to cheat the system so to speak simply does not work.

  2. Water injection when done properly is great, the plan you have though will only end in disappointment.

    We tested the effects that water/metho in a 50/50 mix had on my ute over 12 months ago and the results were a gain of 20rwkw but it didnt just happen instantly. I used a snow performance kit which has its own little computer that lets you adjust the amount of total water aswell as the ramp rate at which the water gets injected. The ramp rate is crucial to getting good results, just using a boost activated switch will cause the engine to bog down as too much water will be injected initially if you are to get anywhere near the correct amount of water being injected at max rpm. You need to find the sweet spot to get it working to your advantage and without that little computer you will be pissing in the wind. You would have more chance of guessing the lotto numbers than of getting it right with the system you were thinking of.

    In short save your coin for a snow performance kit and some dyno time.

  3. I have put some thought into the design of tailshaft loops into xr6 turbos. I use a 360 degree chromoly loop which is welded into place in the transmission tunnel and has been andra approved. They weigh next to nothing and can be fitted in under an hour unlike the bulky bolt in generic versions out there.

    If you would like more info send me a pm and I will be more than happy to help you out.

  4. Not all manifolds are created equal, boost control is something that not a lot of turbo manufacturers take into account and ETM manifolds have the best boost control on the market bar none.

    If you want to have a chat about it brad give me a call on 0242 628 774 or email me at turbomanifolds@bigpond.com and I will help you out with anything you need to know.

    AIM-300 I am not sure where your information comes from but it is incorrect.

  5. On my work ute I have standard coils 160,000klm old the car has been making 400rwkw for the last 40,000klm of its life, run a 10.4 quarter mile,towed cars from melb to qld in near 40 degree heat ,gone to the snow no less than 15 times in sub zero conditions (see pic). I also have an alloy cover plate (see pic) and have NEVER HAD AN ISSUE WITH COILS.

    We have also made well over 500rwkw with another car using stock coils.

    Strawberry you obviously have other problems and are blindly blaming the coils.

  6. If it were on less of an angle the air filter pipe would hit the power steering pump. Fitting a gt42 into a ba engine bay there is a lot of things to take into account that most people probably dont notice when they look at it finished in the engine bay.

  7. That is perfectly normal, when you think about it the burnt fuel is what makes the turbo spin causing boost. As the engines rpm increases it consumes more and more air and therefore the turbo has to work harder to keep the boost level stable. Since you are not applying enough throttle the boost will drop off before the rpm ceases to increase, try it with full throttle and it wont happen untill higher in the rev range where the engine actually consumes more air than the gt3582r can physically supply it and the boost level drops.
