Re: Possible to control KA24E with CA18DET ECU?

That's my understanding, after a certain point the cam angle sensor was added but the distributor signal was kept.

Re: Possible to control KA24E with CA18DET ECU?

Makes sense. You're looking at a lot of work though, but would pay back some novelty factor. The KA up to 94 (?) uses the distributor alone for the crankshaft position signal, after that a camshaft position sensor was added as well. For ignition you may be able to use the stock KA stuff or find a co...

Re: Possible to control KA24E with CA18DET ECU?

It's a niche forum but this is a super niche topic :D I don't think you'd have anywhere to start with but I'm not going to say it's impossible. Fuel and spark mappings would be different, MAFs are different, surely a lot more. You'd have to repin everything. I believe the KA ECU is 16-bit and the CA...

Re: Trouble pulling timing chain idler

Is there a way you could upload a picture or two to somewhere like imgur.com and share links with us?

The piece pictured at 13016 is definitely not fastened to anything. It simply slides into the idler gear and acts as its shaft.

Re: Trouble pulling timing chain idler

The piece 13016 is not attached to the idler gear in any way; chances are it's just stuck in there. The OD of the shaft and ID of the idler gear are very close to each other but not interfering.

Re: line kit for isis t25 replacement

On the stock oil filter housing is a 1/8" BSPT (not NPT) port - you can find an NPT to BSPT adapter and go from there. Another option is an oil sandwich plate which sits between the oil filter and the block, and provides several NPT ports you can use for oil lines, gauges, coolers, etc.

Re: npr piston set

I'm sure they are fine for a "stock replacement", but they won't provide the level of strength you would find in a set of forged (as opposed to cast) pistons. I would treat them like stock pistons, which, depending on the tune can fail below 300hp. Enough detonation/knock will be a quick end to stoc...

Re: Starting my KA24DE-t build soon. Advice needed!

It looks like a good, solid start to a build. As far as CP/Arias, you can't go wrong with either although there may be a difference in the alloys used; one may be ever-so-slightly superior but I am not sure. If you are sticking with stock bore pistons, I do not see why you would need to have the eng...

For finding vacuum leaks, a can of brake cleaner sprayed around the intake components is a good start. If there's a leak, it will pull in the brake/carb cleaner and your revs will increase.

Re: Dual vs single maf?

Wrong MAF will definitely cause the car to run strangely if the ECU is expecting a different MAF. The air flow/voltage output characteristics (I believe you can call this a VQ map?) are different from MAF to MAF.

If you're in a bind, you can use a piston from your old block - but it is my understanding when Nissan assembles the blocks, the pistons are likely cherry-picked by weight/overall dimensions.
