I am going to get a CA18 so with that now in mind here is what I was wondering, I have seen bits and pieces of info on this spread around the forum but lets see if we cant condense a little here shall we?

1)Where can aftermarket CA clutches be purchased (best prices)or is the KA clutch a perfect fit( or what is the best fitting clutch)

2)Is there any reason not to use an izusu black intercooler if I am only shooting for 300-350 HP

3)Will T28 also fit the CA as a direct fit and which/where t28 should be used if shooting for 300-350HP

4)With the Izusu intercooler, walbro fuel pump, intake, exaust, would popping in the Rx7 Turbo 2 injectors benefit me at all as far as allowing higher boost on the t25 or t28?

5)What PSI will achieve my goal and can the stock t25 do this SAFELY

6)Where is the best place for buying boost controllers at the lowest price

7)Is there any sites that are a how-to on CA18 installs

8)Can the powersteering and A/C be retained after the swap and if so is it the CA or KA A/C or P/S systems that are used. also is the alternator kept or is the CA used

I am sure some of these questions are n00l3 but they are things I spent some time trying to figure out. Gimme a hand guys!

1. SR clutches bolt up if you use an SR flywheel. i would get a 4 or 6 puck if you are aiming at 350rwhp

2. only 350rwhp is a lot. if you are aiming that high i would get an aftermarket IC not a junkyard one. get a nice apexi, sparco, hks, or ND core. hks and ND even make kits that will fit.

3. a T28 will fit the manifold directly but 350hp is past the efficiency range of all t28's that i know of. ND's T28/T3 hybrid (what i use) is only good to about 330hp, and the turbonetics big 28 is supposidly only good to 350hp. but why would you want to run a turbo on the ragged edge of its effeciency range? get a T3/T04E if you want to make those numbers reliably. and while you're at it you are going to need to get at least a fuel controller, a chip (or just an ems), a metal headgasket, larger injectors, a larger MAFS, free flowing intake, some cams, and 3" piping from the turbo back.

4. larger injectors will help you from destroying your engine, yes. higher boost on a s14 T28 would require more fuel but you could get away with a rising rate fuel pressure regulator. again tho, for your goals a t28 is just not a realistic option.

5. no, the stock T25 is very small and would never be able to put out those power numbers, let alone do it safely. im guessing with the ca16de inlet cam that 350hp would be around 22psi, but thats just a guess.

6. http://www.wholesalehyperformance.com sells most of their electronics pretty cheap.

7. my site ( http://www.ca18det.net ) will soon.

8. the CA alternator comes with the engine in almost all cases, so you probably would just want to use that since its already hooked up and ready to go. i guess with enough fabrication you could use whatever alternator you wanted tho. a/c can be retained, people have done it, i dont know the specifics of how they got it to work so someone else will have to comment on that. powersteering will work with a KA24DE reservior and CA pump, i personally just ditched both.

If someone can comment on being able to have AC on a CA, that would be great. Not sure I want to put an engine in my car that doesn't have AC....call me a p**** but I like AC in Austin summer.

havent had a chance to dyno it yet. i will know the power #'s after i take it in to get tuned for 550cc injectors.
