Evan Purple240zt Posted October 5, 2001 Share Posted October 5, 2001 Hey guys, one of my buddies is paying me some good money to build him a rice rocket 240sx. We already have the car and plan to get a sr20det for it. My question is whether any of you have done this, seen it done, or know where a good place to get the power plant is. I figured its a hybrid so why not ask. GEE, i wonder if the grand national motor might fit! Whew, may be a change of plans here. Just thought about that. Ill have to take some measurements. Evan PS... any one else notice im OBSESSED with the GN drivetrane? LOL Quote Link to comment Share on other sites More sharing options...
auxilary Posted October 5, 2001 Share Posted October 5, 2001 the sr20det swap is a good swap, but not as good as slapping a turbo kit on the stock ka24e motor. The advantage of the sr20det is that the motor can handle insane amount of boost on the stock bottom end, and put out a lot of power. But you know, you still get better results with bigger displacement along with the same turbo Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted October 5, 2001 Share Posted October 5, 2001 I second that motion!! I've been in plenty of 240sx's to tell you that the SR20DET is a great swap but not as good as turbo'ing the KA24DE. I've never driven an SR20DET 240sx but I'll tell you that it has a reputation for being a high-strung motor and with the same amount of boost, the KA24DET would have plenty more low-end juice while still matching the SR20DET's high-end power if not eclipsing it. About the only bad thing about the KA24DE is that it is a loud motor but just use some dynamat and your problem will be solved. To me, the 50-60 pounds you save with the SR swap just can't justify importing the engine and the hassle of putting it in. However, if you are set on doing this, SR20DET's are popping up everywhere just check out Ebay or ThePartsTrader. Quote Link to comment Share on other sites More sharing options...
ZROSSA Posted October 5, 2001 Share Posted October 5, 2001 lookie here, www.sdsefi.com they did a turbo project on the 240. Douglas Quote Link to comment Share on other sites More sharing options...
clint78z Posted October 5, 2001 Share Posted October 5, 2001 Hmm I generally prefer a little more displacement for some low end grunt. The 2.4l has one of best low end torque of any 4cyl I have driven. Now from what I have read the SR20det has amazing low end torque for a 2.0l, and you would surely make it up in top end. My pick would be an SR20DET, you give up a bit in torque, however the you gain so much up top. Plus who can leave one of these motors stock, 350hp is so easy. The fuel system and all the mods that need to be done to the KA24. A stock SR20det against an turbo KA24, the KA will be more impressive. However the SR20det will be more reliable and can give you more power for less $$ in the long run. Shop around and make sure you get all EFI it can add up.

Guest Anonymous Posted October 5, 2001 Share Posted October 5, 2001 i like the SR20. one of my favorite motors. for info on getting them and what not check out the fresalloy.com forums. HUUUUUUUUGE 240sx forum. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted October 5, 2001 Share Posted October 5, 2001 Oh hey, since you are building up a 240sx I forgot to mention that I do have brake calipers, pads and rotors from a Q45 if you want them. Some folks have installed these on their 240sx's and they work like a dream. Mind you, I'm not using stock rotors or pads, I have Powerstop rotors with Axxis MM pads. If you don't have ABS, these will be even better. Some guy who had ABS installed the 300ZX calipers and said they don't work in emergency braking situations. So anyways, if you want them, just let me know. Quote Link to comment Share on other sites More sharing options...
Guest jens Posted October 6, 2001 Share Posted October 6, 2001 Search the net for a 200sx with a 2.0 turbo. They there available a short time in other countries before they made the new 200sx. Ask if the 1.8 turbo 200 sx motormounts fit i think they do. Look at this english site www.norrisdesigns.com They make 400 hp 1.8 engines Quote Link to comment Share on other sites More sharing options...
Twentyfourouncer Posted October 6, 2001 Share Posted October 6, 2001 I've seen it done before. I think the website to look on would be www.240sx.org. Quote Link to comment Share on other sites More sharing options...

fl327 Posted October 25, 2001 Share Posted October 25, 2001 the ka24 is more common out here isnt it? wouldnt that make it easier to turbo, blow, and turbo again???? parts at kragen, ka24 yes, sr20 no. Quote Link to comment Share on other sites More sharing options...
Guest mospeed1 Posted October 26, 2001 Share Posted October 26, 2001 the ka motor was built for trucks and has alot of low end grunt parts for the sr20 are easy to find they sell the fwd version in the u.s as the sentra se-r 200sx se-r infinty g20 check out se-r.net for more info on the sr20 Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted October 27, 2001 Share Posted October 27, 2001 A turbo 2.4L would be nice but the potential of the SR20 is awesome. Just to give you some idea. One of my buddie's here in Orlando (and also a friend of Stony) has a RHD 1.8L Silvia. It has a T04, cam upgrade and SDS and it ran 12.0 @ 119 with a lot of wheelspin. We estimate about 345RWHP and is driven daily. As was previously stated, the SR20 will make 350RWHP very easily, BUT, remember you will always need parts.

260DET Posted October 31, 2001 Share Posted October 31, 2001 The only 'bad' thing I've heard about the SR20 is that the aluminium block flexes when putting out a lot of power. This claim may have been realised by Nissan when they brought out a race version for some series in Japan. That version is dry sumped and has what looks like a substantial cast iron 'sump', which is almost flat. Such a sump would assist in preventing block flex. I suppose that something similar could be fabricated. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted October 31, 2001 Share Posted October 31, 2001 Isnt the SR20DET illegal to use in the united states because its not approved by the department of transportation or something like that? Quote Link to comment Share on other sites More sharing options...

Guest Anonymous Posted November 1, 2001 Share Posted November 1, 2001 wana know what would be cooler a sr20det in a 240/280 one of the older ones id like to see this.. sence they say those motors are bad for there size and the z is deff bad for the price put 2 and 2 together well you think about it it would be cool Quote Link to comment Share on other sites More sharing options...
stony Posted November 2, 2001 Share Posted November 2, 2001 yep and that was the ca-18 not sr-20 ;> 1800cc motor putting out that much is cool... ive seen a 240 with a rb-26 jammed in it and it was modified 2.6 with putting like 500 to the tires. the thing just tore up nittos 555Rs the. the engine compartment is kinda small and i would recommend an engine that is similar in length to teh stock motor. i like the gn motor for the 240sx as it would stay behind the strut mounts . anything longer and you get crapy weight distribution. my 2 cents stony Quote Link to comment Share on other sites More sharing options...
