I've had my 90' 240SX for about two months now, and the awesome engine that is the KAE is going out, along with the transmission. I'm looking at R32 Skyline front end for the RB20DET. I'm sixteen, not exactly incompatent around tools. My brother who rebuilt his 280Z would definately help along with an erray of freinds. In your opinions how hard of a swap is it. And what are some specifics I would need to change to make the engine work correctly.

Thanks

I cant really follow what you are saying. If you are looking for an R32 frontend, dont do it. Why? Its ugly? If you are looking to get an RB20DET swap, dont do it. Why? Learn how to drive and handle the car first. In my opinion, a 16 year old does not need a powerful rwd car. You are going to kill yourself and may harm others in the process.

i agree with turboS14, first learn how to drive, get at least a year of experience with the car, then.......start thinkin about modding it.

am in highschool(17) and believe me, half the ppl in there who had fast cars......had them wrecked in a week or so.

as for the swap....its easy, get mckinney motor mounts, transmission mount, driveshaft, and get the wiring done(it takes time if sendin to mckinney as they have a lot of work, maybe in that time ya could learn how to drive.)

no custom work as far as mounts or place of engine/transmission.

there's many threads allready, so use the search button.

although I am going to agree about waiting till you are older, chances are you will try to do it anyway.

Start with searching this forum, and you will find all the answers that go along with the swap.

Why you should wait? Well with your new found power, you car will now bottom out the crappy stock struts as you push the car to it's new found limits.your brakes that used to rule, will not save you from yourself as you find those new limits.Your open diff will now be your one wheel free for all.

What does all this add up to??? $$$$$$$

Hope you have a good job

Thanks for your input, I'm glad that you're all considering safety first. The more and more I research this project, the less it sounds like something I want to do. But like I said I need a new engine. I'm most definately not putting back in another tired KAE. Is there much power difference between an RB20 and a SR20? Don't worry about the crazy driving thing, I'm not much for stupidity. And I wouldn't be able to afford the ticket that comes along with it. Thanks again for your input.

power output is roughly the same b/t the sr20 and rb20. Mostly just a cost difference.

swap in a good condition ka24de, start saving for suspension, wheels/tires, brake upgrade, etc... do all that, by then you will have learned the car pretty well, and then start saving for a turbo kit for the ka...

at least thats what i would do in your situation.

Good point dekand

When I did my swap, I pulled the KA24DE and sold it to a guy locally for a couple hundred bucks. He had a KA24E with a nice hole in the block. He has since put in a Kazz LSD and done some other mods in preperation for the eventual RB power.

Good way to get your car back on the road without spending a fortune.

I'm not going to preach to you either, but when I was in high school a few years back a couple of buddies past away in separate car accidents. They were both going over 100mph and lost control of their cars. The reason being... Well both were excellent drivers. Not like stops at all stop signs and were aware of what’s around them but they knew how to drive. You see I would say 7 out of 10 people who mod their cars go for the motor first. Well we all know that’s what’s impressive and wins races or whatever. Before I got my RB I made sure my suspension was well taken care of. I still have more to do but it’s a lot better than stock. Stock suspension is not made for faster driving than the speed limits on roads or cornering like an F1 car. They are made to deliver a smooth ride and get you where you’re going in comfort. Unfortunately my friends didn't think about this at the time and were more concerned about having enough hp to beat the other kids at school. Just because you upgrade you wheels and tires doesn’t mean you have a high performance-turning machine. Just like needing bigger brakes to help stop the power from a bigger faster motor, you need the suspension to back it up too. Trust me with the 125rwhp beat up SOHC KA I had in my 240sx and the tuned suspension was more than enough to have a great time. Sorry about preaching. I'm 7 months from turning 22 and I'm now getting a car that might take some time to get used to.

Werd. KA's rip it up with turbo's.. I'd never swap one out for a RB20DET.

Yeah I was planning on upgrading my suspension. I'm going with KYB AGX's with Tein Springs. Do you think those will suffice? Also Front and Rear strut tower braces. Thanks for your input.

You may want to go with something ride height adjustable.

The factory settings on my Tein Flex coilovers were so low that I had to avoid potholes and speedbumps to keep from nocking my exhaust off. Thankfully they are height adjustable, so I was able to easily add some ground clearance.

bit expensive, and they will rattle your teeth out on bad roads, but the car is glued to the road.

Hey Man,

Glad to see a young enthusiast use the net for good and not for looking at music videos or p0rn. All the guys who posted testimonies of friends losing their lives because they wanted to push the envelope or whatever, have made valid points and I whole-heartedly agree with them (I am a survivor). Learn what you can and don't feel to proud to take advice. You are about to embark on something that most younger men dream about and that's owning/building a really fast car.

Fast cars are cool, but can cost you a great deal in every aspect you can think of. A short story, I lost control of a FWD sentra while racing a ferarri at speeds of over 150mph. I was 32 y/o when that happened and I knew I could drive well, but when a car gets out of control, there's not a whole lot you can do about especially if you're doing those kind of speeds. I lived to talk about it and escaped with minimal damage. I know that I won't get another chance because I've spent my tickets to live in previous accidents, so no more highway fun for me.

My advice to you is learn the game, enjoy the fruits of your labor, but most importantly, if you have a death wish, make sure you're out on a lonely highway by yourself and not on a public street because there's no way you can stop a force fed car to prevent an accident on the city streets and I don't think you want to be responsible for the loss of life because you wanted to have some fun and show-off. But nontheless, there's more than enough abundant information to help you with your quest on this forum and these RB nuts are more than willing to either point you in the right direction or give you the information you need. Take the advice given here on this forum and you too will be having a good time minus the drama associated with owning a fast car.

Thanks for all of your input. I appreciate the concern and I understand your points. But I feel every situation has different circumstances. I don't gamble with my life or anyone elses. I can't really act stupid in my town even IF I had the desire too. It's to small and the cops would get me in a matter of minutes. I am going ahead with the swap, but I'm not going to run top boost on it. I'm going to take your advice and get used to a some what powerful car and gradually turn it up as my confidence grows in my driving. Thanks again for all of your input and concern.

You seem responsible enough. Take it easy in the streets and open it up on the autocross course. Even better, invest in a performance driving school.
