Turbo Kit For The KA24E

[TrueDrifter]

Looking around the forums and didn't see anything about a Turbo kit. I see that a lot of people have turbos on the KA but what did you do, Buy part by part or as a Kit? I was looking at CXRacing look ok to me, (http://www.cxracing.com/mm5/merchant.mv ... _Code=TOKT)

CRX is the same chinese made kit as all the other Ebay brands, ect.

If you want a quality kit for an SOHC, JGS is the only way to go.

Do yourself a favor and don't boost an E motor. The DE is better and has WAY more aftermarket support. Boosting an E is more trouble than it's worth - I wish I would have never done it.

Boosting the E motor was a good move for me. I have less money invested than my buddies and i am still faster. However i will say that it is easier to boost a dohc because of the support. If you are a DIY'er then you should be fine. Plus if you blow them up their cheap as hell to get another one. I wouldn't build it if i was wanting more than 400whp though.

Nelson, what is your setup as far as injectors, MAF, tune?

[nelson8708]

Right now i have a chipped ecu using the EC1 adr/bin modified for 460cc injectors and stock mafs. I am switching to 1000cc / z32 mafs in the spring for some fun with e85 using the EC3 adr/bin.

Just waiting for it to get warm

[Edub1]

How much boost? Do you have a wideband and Consult?

I messed with that stuff for a long time. I ran the same setup as you but when I put in the Z32 MAF I found that it ran pig rich no matter what. It ran OK with just the K reduced for the 460s but still it ran rich.

PS. You will have difficulty with injectors over 550cc unless you go peak hold which requires a paek hold driver which the E motor ECU doesn't have and the DE does. AMS has one for $350 IIRC.

[nelson8708]

i'll be fine with out the injector driver since i am on e85. I seen it done mulitple times on my buddies honda's with crome so i'm not worried. I just decided to go blow through using the stock mafs but, i hacked it some what like the s14 mafs hack. Since its blow though and using a larger diameter pipe i should be able to boost around 10psi before it maxxes out compared to the 6psi that i was maxing it out with on my pull through setup.

[Edub1]

OK but do you have any actual data on what your motor is doing? I assume you are getting this info from hybridka. Has anyone posted a really sweet tune with no bugs for an E motor yet? My guess is no.

I'll be honest, I monkeyed with all that stuff for the longest time, tried every possible setting and couldn't get a stable AF ratio to save my life. I think there is a lot of BS being bantered about over there.

Good luck though. Let me know how it works out.

You can't get the Megasquirt to work, nor the gm ecu, nor the stock ecu, you say the safc doesn't/can't work.....maybe engine mapping isn't for you. Maybe it's not the ecu at all, the e ecu is one of the most fully hacked and understood nissan ecu's thanks to Deviouska.

[nelson8708]

They know what there doing / talking about over on hybridka. Ever since i have chipped my ecu i havent had one problem. Its been chipped for about 1.5 years all of which is on boost. Had a tune on it for my t25 setup and now one on my holset setup also. Will be using e85 and low boost on the 460cc injectors before i do the 1000cc injectors. No i dont have consult or any feedback from the ecu. All i do is get it in the ball park then fine tune it with the safc. Once i get over 15psi if i decide to continue with the hybridka tuning i will invest in consult and a ostrich. It probably takes me about 10 burns to get the tune where i like it (gets old reburning chips). I will most likely go to nistune if i want more power but, the plan now is to have fun with a little more than 300hp (stock block). If i get bored i am going to do a 7mgte swap from a MKIII .

If you went through all those different programs and never got it to work you should have cut your losses and went with a tuned ecu from JWT or something IMHO.

[Edub1]

I'm still into the MSII. The guys at DIY Autotune are working on a bug they found with the extra code. My ECU probably fried as a result of a system flaw.

I tried ROM tuning and tried using tunes that people sent me that were supposedly solid only to find they all sucked. I never tried using a GM ECU although it is an option I was considering.

But anyway, I haven't looked at the car in over a year due to my now owning a 2008 Ridgeline and losing interest in the project.

The reason you have not had problems is because you are probably running around 10:1 AFR and only 6lbs of boost. Ever notice the black soot coming from your tail pipe?

If you want, search the articles section for ROM tuning and you can read my article on the subject. The technique is right but it simply didn't do what it was supposed to.

I mean you can go ahead and try it but I would advise you to first make sure there are other guys out there with solid E motor tunes along the lines of what you are after. If there isn't at least a few by now this ought to tell you something.

Anyway, in the end by the time you deal with tuning issues and with injector issues and with ****ty manifolds and no adjustible lifters and with having to make a custom down pipe and custome IC pipe and everything else, you may as well just swap a DE in there and save yourself the headaches.

Oh and one more thing. If the numbers bantered about are corrrect, larger injectors with a Z32 MAF should put you close to where the stock K and TP settings were so a piggyback should be a pretty good option.

If all else fails I will put my BTM back on and get an SAFCII for fuel.

I'm sorry you didnt have sucess with the rom tuning but, there is no need to take it out on me and hybridka by saying they dont know what there are doing, and that my tunes have black soot coming out the tail pipe. There are plenty of people with rom tuned E motors running around. Me and my local buddy for one, along with undesiredshoe and others on hybridka. None of my tune's had black smoke / soot coming from my tail pipe. I run about 11.5:1 under boost and cruise around 14.7:1 -15.2:1...

I am going to have to go with what bernard said "maybe mapping is not for you". I'm done on this subject.

Good day sir

Nelson, don't get me wrong I'm glad to hear it if that's the case. It just wasn't when I was messing with that stuff. When I was doing ROM tuning there wasn't a single person with a solid e motor tune. I'll have to check back in and see if there are any posted ROMs with setups similar to mine.
