any silvia/200sx owners?

[golfer17]

just wondering how many there were that frequent these forums. i have two 97 240's and two zenki sr20's. one has one in it and the other is my dad's and we're waiting until my sister is done driving it.

i have owned 2 sr20s a 200sx and i know own a sentra se-l can't beat beat them. Hope to turbo my sentra when i graduate in the summer. my friends sr20det blew up so he has every thing i need for my sentra to turbo it.

[Mike Flitcraft]

Buddy has a 240 if that counts. POS at the moment (he bought it for $500), but he enjoys it. He's talking aobut doing all kindsa stuff that I know won't get done...hell I ported his cylinder head, and he scraped the car (honda at the time) rather than put the head back on and save gas in it.

[oduman106]

i have a 94 nissan truck that has the same engine as the 240sx if that counts.

I HAD a 93 240SX with a built SR20DET in it that I had to sell to move out to California (not CARB legal). I've replaced it with a 93 RX-7 Twin Turbo and have regretted it ever since.

I can still remember the first time I drove the SR20DET. It's so frickin different than the POS KA24DE that by the time I drove 2 blocks I was demanding to know why Nissan didn't put that engine in the 240SX here in the states. That was a HUGE mistake on their part. As soon as I drove the car with the SR in it, it felt like the car was a completely different car...like....ummm....a real sports car....a car with a soul.

That engine was a breeze to work on and parts are so readliy available that it was also cheap to work on. The engine is also pertty damn bulletproof.

Don't do it man!!!

[reflexdb]

I've got a '95 240. Haven't done anything with the engine yet...not too much spare money floating around. I have done some suspension and brake upgrades. Even with the shitty KA, it's still a blast to drive. I'm glad to see that there are so many other 240 owners on here. Is anyone else on zilvia.net? Just curious.

[fsae_alum]

zilvia.....hmmmm...not in a long time.

You ought to try www.Freshalloy.com (http://www.Freshalloy.com) It's probably the biggest Nissan forum out there. They have two categories just for 240's (Basic and Advanced).

I have a '92 Sentra SE-R that's pretty much bone stock with 113k on it. It will be for sale in a few months if anybody is interested (I've been out of school a year and a half and getting ready to upgrade).

[Azim]

I've got a horribly beaten up '93 240SX with the good old unburstable KA in it...

Thoroughly enjoyable in an autocross, despite the worn shocks, abysmal brakes, and one dangerously loose TC rod bracket.

nissan put the ka24de engine in both the 240sx and the nissan pickups.

[fsae_alum]

nissan put the ka24de engine in both the 240sx and the nissan pickups.

I know.....they should have ONLY put it in the truck. The KA24DE was pretty good on torque but it's a slouch compared to the SR in terms of high performance. Likewise, there is very little aftermarket support for it when compared to the SR. If you drive one and then the other, you'll realize that the difference is not in the power or the torque but where the powerband is. It's like comparing a Harley engine to a 600RR. Same general principal but dramatically different beasts.

You preferred the 240sx to an FD RX-7? out of curiousity, why? I found the FD, and even the FC, to be better balanced unless you want to maintain drift angles all day. I used to have an S12 200sx with the CA20E... that was a pretty gutless engine, but still a fun car.

[fsae_alum]

While the FD may handle better than the 240 straight out of the box....the 13B-REW in the FD is a challenge to own and maintain. Examples are as follows:

Vacuum lines on the SR20DET = 5
Vacuum lines on the 13B-REW = 78! I am not kidding....78 vacuum lines that control the turbos, emmisions, fuel pressure, etc... that are notorious for drying out and blowing off.

Solenoids on the SR20DET = 0
Solenoids on the 13B-REW = 12 These solenoids are placed in between the top of the engine and the bottom of the upper intake manifold and connect to the majority of the 78 vacuum lines. They are known for becoming brittle over time (due to high engine bay heat in the FD) and having the nipples break off...thus affecting boost.

Time to remove the injectors on an SR20DET: 1 hour
Time to remove the injectors on an FD: 4 hours

Known Fire hazards: SR20DET = 0, 13B-REW = 1 The FD's have had a big problem with a fuel pulsation damper attached to the end of the fuel rail developing a leak and spraying fuel at 40+ psi directly on hot turbos and exhaust (intake and exhaust on rotaries are on the same side). MANY Rx-7's have gone up in smoke because of this.

Detonation tolerance: SR20DET = good; 13B-REW = VERY poor. All it takes is ONE good detonation in the rotary engine and you're doing a rebuild due to a broken Apex seal...just one. On an engine that runs notably hot, this is a constant issue.

The RX-7 is a great handling car and looks damn sexy but some of the systems in the car are just way more complicated than they really need to be when compared to the SR20DET or even the 2JZGTE for that matter.

Having worked on both I'd take the SR for power and serviceability any day. I only preferred the 240 because it had the SR in it....oh yeah...parts for the 240 were much cheaper too. Most FD owners note that RX-7 means "Retail X 7"

i've got an 89 240sx. it's a piece of crap, the wiring is all messed up, the suspension makes all kind of cool clunking sounds. but it's a blast to drive, especially in the rain/snow. i'm planning on getting another one when i get some money and putting an sr20 in it.

[golfer17]

i know about all the 240 forums, i was just wondering if there was any owners on here who had delved into the car much. meaning others who are familiar with fea, cfd, wave, etc and have a love for the sr20det engine. i am contemplating some ideas at the moment, but i likely wont find time for them anytime soon (maybe if i go to grad school).

anyways, fsae_alum, when you moved to cali, could you not just keep your car registered and tagged in another state (like maybe where your parents live)

They're cracking down on that here in socal somewhat now days. A friend of mine tried that with his Integra and they busted him in no time flat. Besides that, I'm 31, have a valid CA drivers license, have a house in CA. Think about it.....it looks very suspicious having a lowered sports car with a HUGE FMIC and an SR20DET registered to a 67 year old lady out of state with a 31 year old resident of CA driving it.

I havent done much on FD's, but I love my FC. The original engine has 140k+ miles on it and running fine, but i took it out cause i wanted to drop a turbo motor in it. While its true that they are more complicated than a 240 initially, all that takes is some creativity. I had the FC down to 4 vac lines, and will be 6 on the turbo motor. The pulsation damper problem can be fixed with another banjo bolt for incredibly cheap, and once the engine bay was cleaned up a bit, its very simple. Oh, and to get to the injectors.. about 15 minutes.

However, both the FC and FD have a much smaller polar moment of inertia than a silvia/200sx/240sx... thats gonna be a more difficult problem to solve without throwing gobs of money, a sawzall, angle grinder and welder at it.

Yeah...If I got rid of my 12 solenoids and the rats nest of 78 vacuum lines under the UIM (which requires going single turbo), I could probably get to the injectors in 15 minutes too. Living in California with smog tests, CARB laws, roadside inspections, and cops that carry photo albums of car engine bays for reference makes it a little hard to do that. You have to pay to play I suppose.

I'm picking up an S13 this summer while on co-op and a standalone to fiddle with. Starting to save up for equipment to start KA Fabrications as well.

cool. good luck with the business. what kind of fsae experience do you have and what are you planning to do/make with the business? I kinda want try to start up a business that is car related on the side after grad school, and maybe do that while teaching at a community college or something.

[RBbugBITme]

Hey thanks.

Its a slow process, but our focus is on higher quality lower production stuff. Right now we're working on a chassis stiffening piece and from there I'll be casting my own custom endtanks for an intercooler kit which will lead into a new intake manifold.

Service wise we're going to be more suspension/chassis oriented for the time being. My partner has been road racing/autoxing his RB25 powered S13 for 5 years or so. We're going to pick up scales for corner weighting, we'll do installs of course, and if they want we can "pit crew" their car during race day and hopefully help shave some time for them.

I'm actually going to look at a car tomorrow for myself so we'll have a RB25 and eventually a KA-T. Like I said before I also want to offer standalone tuning so I'll start with my own car and a Haltech E8.

BTW, new partner... new name... PdV Motorsports

I know some Nissan guys here will think this is hieracy but has anyone thought about the GM 6 that comes in the trailblazer. It's all aluminum (GM claims 402lbs, which is 50 less then they claim for the LS1), high technology piece (4 valve variable exhaust timing), with 275hp stock, almost as much as a RB25 or RB26 which weighs much more. Plus now you've got 4.2L to play with. I'm sure NA it could reach close to 350hp and turbod the sky's the limit. GM has already played around with turboing the 5 cylinder version that comes in the colorados. I've seen this exact motor turbod in a comp. eliminator drag car too.

What do you gys think? Seems like a natural fit for an old 240 to replace the L24 without being another one of those guys to put in a 350.
