Thanks for the link, kind of a let down to find out that this is readily available cheaper than sourcing parts from junkyard. Flywheel $50, machining of flywheel $30, and as mentioned cluthc kit $400. Mind you with duty and shipping to Canada I might be able to squeak this a tad cheaper than what en...

White bunny clutch sort of

I currently have a modified 1990 D21 pick up flywheel bolted to my ka24de mock up engine. I have bolted a 350z clutch pressure plate to this flywheel and it seems to fit. Most of the references to this setup use a 300zx clutch which is 240mm but the 350z is 250mm. For reference purposes I drilled th...

I agree megasquirt gives you room to grow. However the initial setup and learning curve is high. I run megasquirt for my ka24de and I have no regrets. I have also used Microtech on a supercharged rx-7 it is a nice system to use. The trouble with piggy back and rom tunes is that if you never plan on ...

I use Megasquirt to run the KA24DE in my 510 it is easy to wire, eliminates things like the MAF sensor and now DIYAutotune produces a replacement trigger wheel eliminating the start-up problems. Tuner Studio makes things easy and if you run MSExtra code you can get things like launch control, full t...

I woul dthink that this may affect spray pattern but leaking is a band pintle if the leak is fuel and o-rings if air is getting in. Either way I would look at getting some new injectors

Suspension, if you don't have to slow down for corners you do not need as much power to speed up. When a car manufacturer builds a car the brakes and suspension are setup for a certain horsepower and therefore speed. Adding horsepower without suspension will up the odds of meeting a terrible end.

Well if the injectors were adding too much fuel due to a leak then that is why when A/C idle solenoid kicked in adding air things got better, and when the throttle was cracked also better. I think you have found your problem.

Just checked on IATN for Nissan 2.4L stall on decel and one fix was bad vacuum lines would colapse, they look good from the outside but if removed they are soft from heat and collapse. Mostly the hose to the EGR. Not sure if you are running EGR but this may also be present on other rubber lines.

I think that incorrect timing and possible lean mixtures can cause heat, but also you are asking for a lot more from your turbo and engine in terms of power at the higher boost level, which means heat. I would suggest an oil cooler to help when you go back to the bigger setup. Also I like Water Wett...

I will look forward to seeing your dyno with the new turbo and be able to compare the two graphs. I am not sold on the gt3071r but am looking for a turbo that will give as broad of a powerband as possible while making somewhere near 350-400hp

heli-coil

My apologies I missed that he knew about helicoil. However if done right a heli-coil will hold. Stud may break but threads will hold. Biggest downside is that sometimes the coil comes out with the stud, but if the stud is not removed it is good. So lesson learned I will take some reading lessons.

If your friends spark plugs worked good in the car and your new plugs don't it is very definitely a spark plug problem. Check which cylinder is not firing by pulling the wires one by one and when you find that cylinder change that plug.
