preliminary ITB pics.

[Gomeler]

I can't even imagine the gains in flow that ITB's would have on a turbo setup, but my question is, for N/A, I guess the risk of having dust/dirt in your engine is outweighed by the pursuit of horses?

[DaydreamDrifter]

whats up with that crank pulley?

[PandaS14]

Dan: Ahahahaha I love that drawing. best part of this thread so far.

Gomeler: Yeah, ITB's net a much more responsive engine and power on any engine. And once I make some filters. I'll have all of the benefits of ITB's, with no side effects.

Daydream: I had a trigger wheel machined for it. The trigger wheel has a missing tooth and every time it goes past the sensor, it triggers the ignition, then the ignition system fires one of the cylinders. So there is no distributor. I did this so I could have full tuning capabilities of the ignition system, in addition to the fuel system.

[Nismo_Freak]

Please get video of this soon, I have been wanting to do this to a KA for the longest time.

The induction on that big stroke engine has to be LOUD.

can someone throw just a few finished pics of pandas setup on this page. i tried opening the first page yesterday and my shltty webtv wouldnt load it even though had it going for like 10 mins. thanks

[Redline240]

How are you controlling this? What else is needed to run ITB besides the throttle bodies and some way to tune it? Is all that funky ignition stuff necasary? Could the ITB's be tuned with Megasquirt as apposed to more expensive standalones? How does it work without the MAF? And will you need larger injectors?

[PandaS14]

I'll get a vid up asap.

I'm using MS to control this, so yeah you can use it. And it's not really a bunch of funky ignition stuff, it's a distributorless system. Much better (imo) and more accurate than stock. Plus full tunability. You don't need larger injectors if you are under 200rwhp, but above that, yes.

It's all DIY stuff, so you can do it however you please.

[4gotn1]

hey panda. what all is needed to swap to the dis from a escort? because i would love to do that to mine.

[Redline240]

What are you using in replace of the maf? What was needed?

[Redline240]

Oh, and if someone can direct me to a more elaborate explaination on whats needed to do this i'll stop with all the questions, lol...

can someone help a brotha out please. .redline, theres a few ITB threads in this forum that have alot of info in them. i forget who created them or else i would tell ya. search itb in this forum.

[Redline240]

Thanks man, will do...by the way your car looks amazing, low, black, sweet rims...not overdone, perfection!

[deviousKA]

Here ya go j-z, I grabbed some of the pics posted earlier and made them smaller and faster to load for ya. http://www.hybridka.com/ITB/PandaITB.htm

[PandaS14]

Gabe, thanks a ton! I appreciate it as well!

[j-z]

thanks a bunch devious! that loaded for me in like 15 secs. panda, looks like its coming along pretty good. i cant wait to see how she runs. do any of you know where to get an AL intake head flange?

[Redline240]

Ok so its a MAP setup, since there's no plenium or however you spell it...what runner do you put the MAP sensor in?

Redline

[j-z]

you take a vacuum source from each runner and "T" them all into one, and then run that one to the map. i searched itb, recent, and post bodies and found alot of good info. that was in there too. btw, thanks for the compliment. and oh yeah, devious, is your manifold steel, or aluminum?

[deviousKA]

Nah its not steel, lol. I usually mention that when talking about my wheels not my manifold, haha.

1 1/2" aluminum conduit is 43mm i.d., that is what i used for the runners, the flange is aluminum as well and the part is tigged to make one. I do have a steel bracket in the mid section of the manifold that is bolted to the flange, this bracket attaches to another aluminum bracket on the throttles and holds the entire assembly in place (stout). Then i have the simple rubber couplers to seal.

[deviousKA]

A couple more, why not eh? Installed on the beast.





There you can see the brake boost vacuum rail, water neck, wiring bracket etc etc. I have my fpr and map signal for ecu sourcing from each of the 4 runners, same with the brake booster rail. The MAP signal hose that runs along with the harness to the ecu is hardline. All wiring is now sheathed and 90% complete.

[PandaS14]

Devious, HOTNESS!

A little update for you guys. Unfortunately it does not include a vid/sound clip. My friend with the good camera just got it stolen.

After having done enough tuning today that it runs fairly well under all loads under 4500RPM, I've decided I'm going to try out Alpha N' (TPS based fuel map, instead of map sensor). I now know why almost all n/a ITB engines with standalones use this type of setup. This is because under low load (but constant acceleration) you can achieve map values that are the same as WOT. This is a problem because there are vastly different amounts of air entering the engine under the two conditions, but the standalone is looking up one area on the fuel map. so you can tune it to either WOT or low load, and get the correct a/f ratio, but not both. So I'm gonna try out a TPS based fuel map and see if that works better for me. I'll keep you guys updated as progress is made.

Oh and also, the fuel cut rev limiter that you can implement with MS is bad ***! You can set it to any rpm, works great, and it sounds like a friggin race car rev limiter. Love it. haha Also, it cuts until the engine has spun down 100rpm then pulls back up to redline and so on. With a relatively light reciprocating weight like mine, it cycles a few times a second, so it's really fast. super sweet.

[Redline240]

Sounds sweet Panda, keep us updated!!! On a side note, has anyone dyno'd a KA with ITB's? If so with what result?

By the way, did you ever dyno your car?

[4gotn1]

i got a couple of questions.

1. what all is required to swap the escort dis onto a ka24e. im very intrested in this. 2. how hard was it to build your own intake manifold, and what is the best materials to use?
