Re: Flooding when cold

Think I got it figured out, turns out one of the leads to the fuse box was loose where I extended the battery/alternator wire for battery relocation. It was partially pulled out of it's ring terminal, so I think when it was cold it was contracted and making a poor connection. I've got it secured wit...

Re: Flooding when cold

Checked the o-rings, all four injectors are bone dry when priming the pump. I got her back to starting up and idling albeit very rough, had to do so by reloading a stock S14 tune, corrected for injectors and MAF (All done through Nistune) On top of this, I had to crank up the fuel pressure to ~56psi...

The valve cover doesn't get nearly as hot as, say, the head or block and can be painted with pretty much any type of paint. Find something you like and just make sure you do good prep-work and it should turn out great

My money is on a bad injector O-ring, they aren't reusable.

Your impression is correct, it's not very reliable, you will have to control timing via retard at dizzy in order to not blow motor, and even then you'll probably still blow it.
Don't go cheap on a tune, it will determine whether or not your car is reliable.

theoretically: you can run it as high as you can get it

N60 is cheaper than N62 and tend to be much easier to find in junkyards, and as said, above uses the same wiring as an N62 which makes a great starting point. Even if the power rating is similar to the stock maf (going off Nistune, at least), the N60 has a 3" housing which is less restrictive and a ...

I've got an Isis RS3871, it came with an adjustable wastegate. I've lengthened the rod to turn down the boost.

exhaust leak near the sensor will definitely mess up your afr reading. When my car normally idles at 15, it was reading 18-19 even with a relatively small leak after the sensor, and very spastic. I'd recommend sorting that leak out, you want that wideband reading as accurately as possible if you are...

The original setup I had cost about $1500 for a t25, manifold, injectors, fmic, exhaust, and nistune which outperformed stock sr20's
Since the majority of the 240 community views the ka as garbage they are selling KA's for dirt cheap, you can get a running motor for less than $500
