APEXi VAFC question(s)...

Posts: n/a
im building a jrsc'ed b18c (6psi) that will be transplanted into a crx for my new daily driver. i already have the jrsc, jr btc, jr fmu, boost gauge, af gauge; and i am planning on getting the jr map controller, 255 lph walbro fuel pump, and a mechanical fuel pressure gauge. im wondering if i should also get an apexi vafc to be safe and make sure im getting the right af mixture. anybody else use the apexi vafc? i found a place that i can get them for $260 shipped; is that a decent price? tuning-wise; could i just cruise down my road gradually accelerating and making mental notes at each 500 rpm increment what the af mixture was, then adjust from there?
you could do that or just get a rising rate FPR and not have to worry about it at 6 psi daily driven. Its all in your preference and how deep your wallet is.

True, as for the ghetto data-logging, you could use a video camera and record the a/f ratio, rpm etc and play it back. Ghetto fabulous!

And what are you planning on monitoring the afr with?</TD></TR></TABLE>
tried going turbo, but im just too damn stupid and lazy and work at it. there was just way too much **** to handle for me. only way i could get a decent turbo system was to piece one together and that went NOWHERE. for the sake of simplicity and my sanity, i went with the jrsc. didnt i post that i had an air fuel ratio gauge (af gauge)? i actually have a crappy digital camera (pictures turn up looking like dotted ****
) thats able to take pictures really rapidly if you hold down the button, which would work better than a video camera, imo.
btw, for tuning, should i floor it to get the most accurate air fuel mixture (heavier load than at half throttle, for example)? also, my pockets are as shallow as a red neck kids pool.

Okay, if you say so. There isn't anything terribly complicated about putting a turbo kit togather... All you have to do is ask for help if you need it.
Full load is going to be the time when the car runs the leanest. SO, yeah that's where you need to do most of the tuning.

i did an *** load of asking since i knew jack **** about turbos. everytime i thought i was on a roll, somebody would mention a whole new set of problems, complications, and other **** i had looked over. just too much for me. i deal very badly with stress; either i just say "**** it" and give up, or i start breaking **** which pisses me off and its like a horrible chain reaction.
any specific gear it should be in? if not, flooring it in 5th would make me able to almost tune on the fly. btw, i have a crv pulley (8 psi); how much additional wear/stress would it put on my engine if tuned with what im planning on using? would i have to use an octane higher than 93?

Well, I know how you feel. Sometimes I throw **** too.
A turbo kit is much easier to deal with imo then the jrsc. There isn't really much to need to know about them either... It's simple.

I'd run it in third or fourth. The afr gauge isn't really the best way to do it... But as long as it's pretty much all the way on the rich side whenever you floor it you should be cool.
Listen for detonation. Be ready to pull timing out. There is no intercooler with the jrsc, so the air going into your engine is very hot. This does not give you much of a threshold for detonation.
I know 2 people around here that have jrsc... They run 2 gallons of c12 per tank of gas just to keep it from rattling. You might want to check out tolulene.

of course a turbos easier for you; youve been dealing with them for awile
.
cai is going to be a must. how would a vis cf zc hood with a hole cut out for like a wrx style hood scoop leading air directly onto the jrsc work? anything to worry about when it rains or snows, even though id have a cai with an aem bypass valve?
c12 and/or tolulene, hmmm... i think ill stick to 6 psi for the time being
; dont need 8 for daily driving.

Yep you did. But is it just an autometer (or like) thats hooked up to your stock o2 sensor?
If so let me ask you question. How are you going to know what your air/fuel ratio is? That gauge won't do much except show you a few pretty colors....
Now if you actually have a wideband o2 sensor then thats a different story.

better safe than sorry; something like this: http://cgi.ebay.com/ws/eBayISA...40930
^ that what youre talking about? to install it, would you just have to unplug the stock narrowband o2 sensor and then plug in the wideband o2 sensor?
im budgeting myself like crazy and so far; with all shipping costs, labor, and high estimated prices considered; i have $1k, if not more, left in my budget. ill try to recall everything:
crx: $400
b18c long block $1800
p72 ecu: $200
cable tranny (b18a or b16, undecided): $400
engine mounts: $400
jr map controller: $170
jr fuel pump: $150
fuel pressure gauge: $40
b18a axles: $100
apexi vafc: $260
labor: $500
by my calculations, i will spend $4420. im going to do about half the labor (easy stuff: wiring up everything + jrsc installation) and leave the rest to a friend of mine who works on exclusively hondas and vws every single day of the week (did an engine swap for me in the past for $450; excellent quality
). my budget is $6k with a $7k roof, so it SEEMS im doing good. spending hours upon hours shopping pays off
.
btw, whats the differences between a mechanical and electical boost and af gauge? how can you tell the difference?

btw, would one of those stick on hood scoops put through a vis cf zc hood with the edges welded/glued/"attached" on the underside of the hood directly over the jrsc work as a decent way to cool the jrsc? yeah, yeah, i know; that would be SUPER-GHETTO, but its better than forking over $1k to lht performance. how would i go about doing that? make an out line of the outlet of the scoop, mark that outline on the part of the hood directly over the jrsc, then cut away?

after some extensive searching, im thinkin the new sti hood scoop would be my best bet. all the other scoops i found were too long and didnt fit the general shape of the jrsc, which is more wide than it is long. any comments? or is the $100 to get an sti scoop for a ghetto way to cool a jrsc too much?

considering putting in a 10.5:1 cr cammed b18b with a block guard into the rex now; wise decision if i can get everything for the same price as a b18c long block? need a tougher crank?

ok, ive ditched the b18 crx plan and im going with a 300hp na 3.0 cl (that leather feels sooo good). i know that ill need a wideband o2 sensor to properly tune, but arent 97+ cars obd2 and have 2 o2 sensors? will i need 2 widebands or just one? which one? are they both the same?
