why a ca18? its going to be harder to reach those numbers with a 1.8L engine, good luck though

 

cheaper and better block than a sr.

run 18 psi and you should have an issue... i'd prolly get a GT32 or GT30 though.

 

A GT2871r should hit 300 wheel I thought...Let me know if I should buy a bigger turbo. I want to get a FMIC this week for fab up purposes. What size do you think I should get to support 300 whp, not heatsoak and not cause a ton of lag.

 

Yes it can, a .64 A/R(IIRC) should yeild 350ish and an .86 A/R around 400ish, an eBay IC core should be good for 300(http://cgi.ebay.com/ebaymotors/2-75...QitemZ320171422706QQihZ011QQcategoryZ33742QQssPageNameZWDVWQQrdZ1QQcmdZViewItem)

 

Don't forget about other things like fuel pump, fpr, maf, and tuning of course. Definately a wideband if your gonna self tune.

Wei

 

I understand all this. I'm not new to cars or any of that. I'm just unsure on a few details and those are the ones I'm asking about.

 

I'm getting an Yonaka(sp?) intercooler. What size do you think? Big as I can fit? 2.5 or 3" thick?

 

you can fit a 3, but that only gives you more weight you dont need and lag due to a small turbo only making 300

 

Bought an 18x9x2.5 core size and 26" total width.

What injector size should I be looking for?

 

Your biggest problem is going to be fuel management... You need something to tell the ecu you need more fuel at a certain rpm, or all of your winter investment goes boom. Some guys are good enough that they can use a wideband + SAFC to adjust it enough to make it run decent, but I would suggest some other type of piggy back at the very least. Lot's of people use the Emange Ultimate, and it is damn near a standalone as far as tuning capabilities are considered. So make sure to look into it.

As for the turbo, I would go with the gt3076r. 550cc injectors should do it, aftermarket fuel pump such as walbro or a tt300zx or supra pump, that intercooler is pretty small, but it doesn't need to be huge to be effective - I hope you know/are a good welder. The exhaust should be rather easy. All that would be needed is a custom dump and downpipe.

That should net you 300whp pretty easy on 10psi, but the turbo is big enough with additional tuning and some more psi, it could net 350hp if you ever choose to do so!

 

Well I'm at a point were my 300 is just what I want from this turbo. Next year I'm buying my buddies 35r. I also want internally gated for now because I'm sticking with the stock manifold. I am a good welder but I was told you can use an SR down pipe and O2 housing. Am I wrong? My exhaust is an Apexi Noir Catback.

So an SAFC won't cut it for fuel managemnt? Does Power FC work with the CA? I want to stay away from Emanage because everyone I know that uses it has bad experiences.

550cc injectors do sound like the size I should be going with so thats what I'll get. I plan on getting a Walbro 255 for a fuel pump and obviously a regulator.

 

stock o2 housing should fit, it may need some filing on the bolt holes though. maybe a little.
you can probably get a power fc for the ca if you look hard enough. just find one for a 180sx. as far as emanage ask bojangles.

 

Not if, I will find a PowerFC. End of story there. Just purchased a Synapse FPR. Getting a Walbro later this week.

 

Why wast all the time and effort looking for a PowerFC, just ROM tune it, or get Calum/etc to do a realtime set up

 

a power fc can do realtime map value changes or changes to any other value, at realtime, with fc datalogit software. buying the fc datalogit box and software is very worth it if you plan on tuning any of it, any time, yourself. otherwise the only person that will be able to do anything cell by cell REALTIME would be a lisenced apexi tuner, using their software. you can edit cell by cell with a hand commander that comes with the power fc, but its alot lot better doing it on a laptop with the software.

the power fc iseasy and convinient since you just swap out the ecu, plug in some shit, plug some shit to your laptop, do the idle correction and go drive. thats why i like the power fc. simple and less problems. if you live where its nice most of the time, and want to make a shitload of power at a later date get a d jetro and convert to map.

also you can tune the stock ecu with rom tuning. or a daughterboard setup. im not too informed on that shit though. for rom tuning just contact enthalpy. hes all you need to know.

 

Educate me on whats out there for these cars as far as tuning. I was going to do SAFC and some kind of chip but I wasn't sure if anything was out there. Thanks for the help.

 

why are guys suggesting enormous turbos for 300hp. gay. i hit ~220whp at 7-9psi with 450cc injectors z32 maf and a shitty tune giving me 13.0 af. on a gt28r. deet..300 will be no problem on this turbo. 2871 is good for 400. 3076 is good for ~500.

 

The biggest question I'm at right now is what I should be doing for tuning.

 

piggyback. greddy emange with the ignition harness. emange ultimate. aem fic, megasquirt. etc.

 

^^^ wrong screw piggyback systems when there is stuff like calumsult out there its all about the real time daughter board or full standalone stay away from piggy backs. emanage ultimate is the only decent one and its not that great especially since calumsult blows it away in price and usability.

 

how about eat a dick. i have first hand experience having to worry about writing/burning/chipping ecu's. try datalogging on a CA without a piggyback. you cant. have you had experience with any of the system i mentioned? i love how you have to put your 2 cents into everything. but now that you have, whats wrong with a good piggyback that you can datalog, tune realtime with fuel and ignition, not have to even open your factory ecu, and monitor engine parameters while driving?

 

Is there ways to tune the stock ECU? That would deff be the route I'd like to go otherwise full stand alone. Piggybacks are just half assed.

 

i wouldnt say piggybacks are half assed but they do their job and are appropiate in some cases. if i were to spend 450 on emanage ultimate i would just get megasquirt but even some people would say MS is half assed. its just preference. im doing MS right now so of course i think you should too..

 

No one has answered my question though. Is there ways of tuning the stock ECU?

 

1300 for an AP Engineering power fc is a little steep though. plus a boost control kit. meh...

atriczap. yes. CA ecu's are rather easy to chip. i have a chip i can sell you. i have a socketed ecu i can sell you too. you can take out the factory 28pin EPROM and solder in a socket. unless you have an emulator its a pain in the ass. its one of the reasons my shit isnt running and has never run right and im going standalone

 

Also, since this is for a CA, it has an 8bit eeprom chip, meaning you can directly socket the ECU without needing a db. Also, because of this, you can pick up a moats emulator for pretty cheap and do real time tuning directly with that, and not need to burn chips etc.

However, the CA ecu does NOT support Nissans consult, so, you will need a stand alone widevband o2 with data logging atleast to tune.

 

wanna buy it?

tuned for 450cc injectors, z32 maf, timing good for 20psi.

I think I'm going to go with that for my CA....




Is that .bin for that tune something you would/could share with a fellow CA18 tuner?
