thanks alot man

Hey guys, I have an autotragic 91 240sx with a ka24de

Well my uncle has a 89 240sx with the ka24e that is a stick shift thats not running. I was wondering if I can use all the parts from the 89 240 and convert my automatic into a stick? I heard by word of mouth that the transmission is interchangeable. Do you think I can get all the parts from the 89 and put it into my 91 and make it a stick?

Thanks guys.

[AZ89two4Tsx]

Yes the transmisions are interchangeable. The KA transmission is also interchangeable with the sr20 and ca18, all you have to do is swap the bellhousings.

ok im in the process of buying a 180sx with blacktop. i was told by the previous/current owner that the wastegate "does not open "and the car will start and run but when its out of 1st gear it kinda bogs down and you gotta give it some throttle to keep it running.

a friend said i have 3 options

1. external wastgate2. replace the T253. get a bigger turbo since im taking it out anyway.

i was wondering what would be the best/easiest way to go about fixing the problem.

[AZ89two4Tsx]

^ Definately replacing the turbo. If that is all that's wrong you just replace the stock t25 (which has it's own wastegate) and you're done. Of course if you're wanting more power than you should upgrade the turbo. But by far, just replacing the turbo will be your easiest and cheapest option. SR T25's can be had for pretty cheap as far as turbos go.

IIRC you also need the flywheel for the application, as well as a pilot bushing.

this queston is directed to papa smurf

u in he past have answered very important questions to the t for me and the 240 u helped me with sorry to say burnt down . to the fact of bad wiring by a bad company were i live . enough said iam looking to buy a guys 1989 240sx hatchback with a rb20det . with that said the body and interior is in grat shape and the motor has 55,000 miles on paperwork to prove it . i am not expernced in rb20 det . do you have any suggestions on wat to look for , that is diffrent from regular 240sx motors . thank you in advance and wat would be a decent price for this

[PapaSmurf2k3]

I'm also not familiar with the RB series motor. I always get TONS of questions on them too... really really weird ones.

Just ask the owner where he got it from and if he knows a good spot to get spare parts... most of the questions directed towards me are about getting replacement parts (alternators, etc).

I guess you should also look for some shotty wiring so the car won't burn down again.

[nismo guy]

thanks . and th motor runs great just runs a lil rich when first started then 30 seconds later its fine . has been sitting in his garage for 3 years . he had kids i guess that kills the car lover in him . and he onl wants 3 grand for it . better than a pos one with rb in it the guy was selling it for 9 grand , and it was shot inside and out lol i guess iam getting a deal of a life time

[PapaSmurf2k3]

yeah I'd pick that bad mofo up for 3 grand.

thank you, i will try to find a t25 then. i have another question.

the brake lights are always on and eventually drain the battery, so im guessing its the switch. the question is, does the usdm 240sx and the jdm 180sx share the same brake light switch? im guessing they do, justmaking sure because im having trouble finding one here in japan

[AZ89two4Tsx]

^ Unless Smurf can answer that for you I'd post that in the 240sx tech section. I'm by no means an expert and more people would see it if your question was posted there.

[nismo guy]

for sure papa smurf iam go buy it today and should get some pics up today too

Yeah, you could probably even use a switch out of something else if you can make it work. A switch is a switch is a switch.

I'm extremely new to the import world, but I've been an american muscle person for quite some time. I've built many motors and restored many cars. 240 sx is by far my favorite import. I really like the 95. Well anyway heres my question. Is it extremely difficult to rebuild a fuel injected motor if say I purchased the sr20det motor build dvd's. I dont want a car I can't work on. Is it that hard to just step in and take over with proper guidance from the dvds if I've built carburetor engines before? This will be the determining factor whether or not I am to buy a s14 or not. Thanks for the excellent forum.

[needfaster240]

yeah, could be MAF, or bad injector. Hell, it could even be an O2 sensor. Try pulling your sparkplugs and see if they all look the same, or if one of them is blacker than the rest (indicating one of your injectors is bad).

ok finally checked it out to no avail!!!! coolant temp sensor good, mas air good, no codes, and injectors not leaking...... took it for a spin and 20 miles later still nothing. it looks like the ecu had a brain fart!!!!once again papa smurf thanks for the help!

Yeah, there have been people with little to no mechanical experience at all jump into doing these swaps, so you should have no problem with your mechanical background.

You should make an intro thread and try and include some pics of your past builds. We NICO folk love us some muscle cars!

OK then! Intermittent stuff sucks the big one. Keep us posted if it happens again.

trust i know!!!! but i will keep you posted....hopefully someone else will learn from my goofs and problems.

[importconversion]

If I get a car I really dont wanna go through the trouble of swapping the rb25det, but just wondering how much horsepower is attainable with the sr?

[dickie]

assuming you buy a pre-swapped sr, its more than capable of making the peak hp numbers you are looking for.

the question you should be asking is, which motor would be better for my goals. the person you should be asking this question is yourself. you should figure out what you want to do with the car, then take a look at the basics of each motor, look around those engine subforums and see what other users' experiences with each have been, then form an educated opinion.

i have a friend doing an rb swap, he will probably love it. then again, he knows what he is headed for. for most people, going rb is not cost-effective compared to an sr when you factor in the work and parts needed to install each and get them running.

RE: your brake light problem..Check the brake pedal itself. They have a ribber plug that gets old and brittle. It breaks and there's just a hole left in the pedal. The stopper was what contacted the brake sensor plunger. With it gone,there is nothing to push the plunger back in and brake stays on. I've had to do this on two s-13's already. You can get a new plug or just replace it with a small bolt,screw,or super glue a penny across the hole. just something to push that plunger...

What kind of reputation does Arospeed have for coilovers? I've been looking around forever and can't seem to find any opinions on them. Thanks

[odmoht]

Hello all, i need someone to verify my situation kind of.My car has been over heating recently and frequently , i have a new thermostat , flushed the rad for air bubbles and a new rad. cap. When my brother checked it out , he said the lower rad. hose wasn't hot/warm(it was cold, you can say), and he said it could be my water pump. I want to know if he is right because i want to know for sure before i buy a new water pump.oh and none of my hoses are leaking either.

Thanks

[hockeyhelmet0727]

what is the size of the exhaust going into a atock muffler. and if i wanted to take off the stock air filter doo hickey what size fitment would i need for a new air filter. on a 95 se don know if it matters

[justinedible4]

Whats crackin lackin?!?!Im new here and I am planning on buying a 240sx in the next few months. I am planning on buying an 89-93 and doing a silvia front end conversion. My question is when I do the conversion will the replacement fenders, hood, bumper, and lights fit in place of the old ones or will i have to buy/make a separate bracket to mount them.Thanks for ur help andTHIS IS THE GREATEST SITE EVER!?!?!

[PapaSmurf2k3]

Maybe you should search for Aerospeed? I don't know, I've never heard of them either. Good luck.

The lower radiator hose isn't supposed to get hot. The upper does. You might think that you've gotten all the air bubbles out, but you probably haven't. 240s are notorious for difficulty in bleeding (coolant systems and clutch systems). If the upper hose is hot and the lower is cold, your pump is working correctly. You'll have to open the bleeder hole above the throttle body (when the car is cold), start the car, and massage the hoses until you don't see anymore bubbles. Good luck!

2.25" AKA "two and a quarter inch". For the air filter MAF adaptor, I think there are a couple different sizes. Just search for cone filter adaptor on Ebay or something.

I'm pretty sure fenders, lights (with supplied brackets?), hood, and bumper all bolt right up. The only thing I'm not sure about is whether or not the lights need brackets.

Hi I have been looking around here for awhile and liked what i saw.I am looking at 240sx's for a starter car and had a few Questions about the car. I have looked but i figured you guys would know, how much would i expect to pay for a good condition car with under 100k. Not picky about the year. Can they be entertaining stock or are they as balless as they say. My plans were to pick up a nice car then save for a turbo but that gap would be awhile so I don't want to get bored with it and sell it.How do these cars handle stock, I hear its pretty good. Would this car be expensive to buy parts for or get it worked on? Would a 300z be better for me?I have used the search button

Thank you alot

[justinedible4]

thanks PapaSmurf2k3ur info really helped

[odmoht]

another question...i kinda broke the top of the bleeder bolt , the one on top of the intake manifold.how do i get it out?

thanks again.
