Forcedtorque's new project

[ForcedTorque]

I just got home from a 14 hour trip to Atlanta or 1/2 way between Atlanta and Macon. I got a great deal on this 89 240, and it came with a KA24 and an SR20 (both good, and both with harness and ecu. The moptor you see on the trailer is the SR20 twin cam black top motor. It will be for sale if the KA install goes well. The KA is sitting in the body, but no work has been done. He put it in there so I didn't have to try to get a car and 2 motors on the trailer, but it's just sitting there. The body and interior on this car are in excellent shape, except for badly faded red paint. Absolutely no rust, or any body damage, and the seats are perfect as well.

I promised my 15 yr old son one of my turbo Supras when he turns 16 if he stayed on the A/B honor roll. He came close, and probably deserves the Supra, but he didn't quite keep it perfect, and I realized what a 16 yr old boy in a Turbo Supra would do to my insurance. With this car, he can learn how to drive first, then as he gets a little older, he can modify it to race with Dad. hehehe

 

[GotToyota?]

Ah come on, give your son the SR20. Looks like a nice start, I wish my dad would've done something like that for me.

[suprahero]

I don't know anything about 240 engines FT, but I'm glad to see you got your son something to drive around in. I'm sure he'll really enjoy it. Is he going to help you install the motor. I bet that will really make him enjoy the car more, knowing that he got it to run.............lol

 

[OneJoeZee]

use the SR!

 

[ForcedTorque]

I thought sr20 too, but all the Nissan guys on another forums say KA is better and easier instal

 

[OneJoeZee]

ha. put the SR in if you ask me. then you dont have to worry about turboing the KA in the future or anything.

 

[Oni]

too many 240s on the street =/ ... drop the KA in a 200sx!! ^_^ FTW!

they lied to you

 

[bobiseverywhere]

KA came with the Car and it's from a Truck still an ok Engine but for more Aftermarket and future tunning i would deffinatly go with the SR20

there are things for the KA but it takes allot more cash to get it to the same point as the SR20 the SR would probably be a better starting point for him

Why does this sound like a 7M vs 1JZ discussion

The SR would be a better engine to put into the car, but would it be a better engine to put into the car for him? A turbo RWD car in the hands of a 16 year old may not be the best idea. I would suggest you leave the KA in there until he's learned to handle the thing, then if he wants more power, you can teach him how to swap an engine.

You do have some good points there.

I would say it really comes down to how much you trust your child to listen to what you say about how he drives the car.

Another point i can think of is. there are allot of cheap new cars kids are getting there hands on that have nearly or just as much power as the SR. Plus that SR is old so it's not pumping out the same old stock Power that it used to.

Depending on the SR and it's year. It can be pushing anywhere between 205HP to 250HP at the crank



For the most part. It would be fun for the kid to have a Turbo car. Lower Power numbers like that means it's still a blast but he can't go buck wild like having a 300HP+ Supra. My first car was a Supra that i bought with my own Cash.

Honestly if you understand what it is and you respect the car and what it can do. As well as understand your limits you can be ok. But that still all comes down to the person behind the wheel not so much there age. Not to say age has no Factor in this

Teach the boy to drive well it won't stop him doing idiot things but it may give him enough skills to survive them when he does! (sign him up for some advanced driving courses)

Doesn't matter what motor he has 60 mph into something solid will kill him.

 

[lifesnotfair]

The people who prefer the KA over the SR are those who think "there is no replacement for displacement", and for those extra 400cc that the KA has over the SR, they prefer it. ST**ID! If you ask me.

The SR20DET is a great engine, it's made to race, it's already turbo... why go through all the problem of turboing the truck-like KA24? The 240's are not that heavy and the 2 liters of the SR will make that car move more than nicely. ...

However, because of his age and that stuff, maybe you wanna go with the KA for the moment then.

 

[Ma70.Ent]

I thought this thread was leading along the lines of putting the 7M into the 240SX. lol.

 

[ForcedTorque]

Good information! Thanks everybody. I must clear it up a bit. Neither motor is turbo at this time. I don't know Nissan motors at all, so I don't lnow if the sr20 was ever offered N/A. This one is black top, and twin cam, but it does have an exhaust manifold on it that is for an N/A. The cam covers have fresh black paint on them, so I guess it may not have been what I was told it was.

 

[lifesnotfair]

Yes, the SR20 was offered N/A, with the Nissan Primera, for example. (Infinity G20 in some countries). The SR20 also came in the Pulsar, which is an AWD vehicule, so they use THAT one in FWD vehicles. The one for a 240SX is different as it's RWD obviously, and that, I don't know if it ever came N/A.

 

[foreverpsycotic]

if i can remember correctly the ca18det came in the 180sx hence the 180 1.8ltr
the sr20de came in the 200sx, nx2000 as FWD
bluebird as AWD
silvia as rwd

the silvia is the same as the 240, except that it has a sr20det in it and the 240 has a ka24. all silvias from s13-s15 came with the sr20

either motor stock is enough to get the car sideways while stock if you really want it too.

wither motor will bolt up to the tranny in the car, and if i remember you can get a mount kit for the sr20det for relativly cheep.

SRs aren't very fast stock so it's not like he has so much more power to mess arounds with than a stock KA. but if you already have the SR, just use it now and you have a great platform to upgrade with in the future.

 

[Wills7MGTE]

I got my supra at 17, havent wrecked it yet, and 240s are not to good in a wreck, the KA is a piece of junk, I know 3 of the 240 lovers here one with an RB26 swap, the other has an sr20 and then an NA-T KA. The NA-T is unrealiable and has been rebuilt 2 times, the SR20 managed a mere 400rwhp after spending 20k on mods and he has blown it 3 times now so its a money pit, hes 60k in debt over the car because hes stupid. The RB26 is stock with a 5 speed off a gtst skyline I believe and it does very well its got exhaust FMIC, intake and boost controller on stock turbos and it smoked the 400hp sr20 the 4 times it ever raced it.

RB26 It's worth the lil extra in cost.

RB20DET ftw!
