Okay I need some direction!!

[l3thalyendl3ss]

Okay small history, 91 180sx conversion ka powered na, standard bs I/H/E, throttle body( BBK ), xcessive intake manifold, aerotech fuel pump, hks fuel pressure reg, 3 angle valve job, 10.5:1 compression cp pistons. no standalone. stage 2 luk clutch

Okay heres the issue my 3 and 4 injectors are failing, I was thinking of replacing them with some rc components 555cc injectors and grabbing some cams, moneys not an issue car has 190 on the chassis, about 10k on rebuild, so heres the nitty should i just swap a ca18det and go trubo or continue building the ka with lower compression pistons and redo the valve guide rods and and seals along with different cam springs following up with ti retainers or just build the ca18det.

This is not my first ka powered 180 this is the second time around and i dont want to f it up so someone give me a little bit of help in trying to make up my mind. :

[sOhcS_13]

personally i think the ca is the way to go, its a very strong motor with good design, plus it would be more correct to the 180sx too. i plan to do the ca swap in my hatch, so im a little bias.

[OutToWinPAHC]

Fresh motor, what are the current rebuild specs?

[PapaSmurf2k3]

why not just replace the current injectors?

Maybe sell the car and get another one if you want to go turbo... it would be a shame to rip that engine apart again and replace all its components.

[nifares240]

why waste a nice KA! get another 240sx or whatever you wanna call it and turbo it if money is not an issue. replace the failing injector, and please get a tune for that KA. this way, you'll have a running car to get around while you're working on the CA swapped on the other car.

well ive also been considering a vq swap and single turbo or a rb swap as well i just said ca18 for the simple fact its really accessible ive been looking around too a company in japan called tiger japanese sells swaps cheap problem being the engines have to be shipped here from JAPAN F that i dont want wait that long I want this running before the end of jan not march lol,

Btw the car has been tuned at a local subi shop only place i really trust with the tune and dyno

Iam still torn between each, all have good points about each swap Iam just simply considering rebuild the ka and going turbo but its gonna cost the same as a sr20 red or black as well as a ca18det along with intercooler and fittings, piping etc.,

Iam still trying to find builds of each with the respective parts but everyone else also choose's there own parts which makes each car unique hense the scene anyway anyone out there with these swaps let me know

[OutToWinPAHC]

Once again you said rebuilt motor. Is that rebuilt with goodies, or OE rebuilt? People push stock KA's into the 300's all day. Makes sense to me to use the fresh motor VS buying an unknown used one.

[laxands13]

i dont know if you read the full description or not, but Tiger Japanese doesn't appear to include the ECU as well as some other parts with the $900 ca. just pointing that out..

[l3thalyendl3ss]

yeah the motor has been refreshed with cp xtp 10.5:1 compression stock oem size bore 89.5mm, toga +.25 race bearings, ams full gasket kit from the intranet, water pump gmb oem replacement, toga high flow oil pump as well. I spent some time researching and this is the best I could find for my budget at the time, the rods and the crank haven't been touched excluding the the wrist pins from when i changed them with the xtp kit.

Iam also looking for a better distributor cant stand this pos black s*** I want aftermarket hard to find tho

I think I found the grandaddy of all swaps http://us.ebid.net/perl/auctio...ebase this is also a possibility dont know tho let me know

[l3thalyendl3ss]

okay i think ive decided on the swap heres the run down correct me if Iam wrong someone

Rb25det 2500 Nitto RB series high volume oil pump 1400GT3582r DBB spool fast turbo 1200HKS F-CON V PRO GOLD 1700SARD injectors 700cc 610greddy tic downback 480

ill throw an extra 1800 on odds and end parts maybe more

thats the current list allmost 7 gs worth or more work to shell out on the car

[visser003]

Keep in mind, the engine you will swap for your fresh ka will have an unknown amount of miles with unknown usage.For MUCH less than any swap choices, you could get some lower compression pistons + forged rods and boost 20psi all day out of whatever turbo you were planning for your 'swapped' motor.

Also, the motor you swap in will have stock internals...so it will not be nearly as strong/resilient as a built KA.

P.S- $1400 for an oil pump? You sir, are an idiot.

Hi reving/power rb's, hell even stock ones that spend to much time in the upper rpms bouncing off the rev limiter have a nasty habbit of shattering the gears in the oil pump, stock or after market. The tomi and nitto pump are retard expensive, but they can by far take more abuse than any other pumps on the market. The only down side to them(other than price) is that they require a larger pacity sump, because they can and will suck the stock one dry.

Look at it this way, you spend the $1500 on the oil pump, then you are much less likely to spend 2x the money on rebuilding the bottom end after a bearing spinns because the gears in the factory oil pump broke and the motor lost oil pressure.(then you also spend the $1500 that you should have to begin with)

[visser003]

You schooled me sir. Thanks.

Yet another reason for me to not swap in an rb

[kouki munster]

Don't let that turn you away from getting an rb, just remember that the chances of it happening increase as the power increases, expecialy if your doing something that has it bouncing off the rev limiter on a fairly regular basis. A soft cut rev limiter helps to keep some stress off the pump gears to. (don't get me started on the hard fuel cut rev limiter that nissan used on the rb )

[visser003]

Well, first off...the RB is a hefty motor so that cuts it out of the running for me.

I wouldn't swap a motor that weighs more than +50 lbs or something that would throw of the balance of the car.

To me, power isn't everything...power with control is where its at.

[l3thalyendl3ss]

okay if you think taking care of my daily driver is something that shouldnt be done. I have a couple of friends with rb swaps and they all have bought this same pump one of my friends is boosting 20 all day every day with no problems with track use as well as drag use (I live 10 mins from Firebird raceway) so if you think taking precautions is stupid with a 20k car, well then guess what sir you are the a**. I guess it all falls back on how you were brought up and they way you were taught to take care of things.

BtW: swap hasnt started will take detailed picks of the rebuild and post.
