Since the 240 is gonna be running on 7 psi (14 psi is stock) you might beat him if you have I/H/E.

Weight is around a 200 pound difference or a little more. A stock 240 is around 2700 but since the SR is lighter it might be 2650 or 2600.

So it might be 50/50.

Have you ever owned a 240 before? I don't think so b/c what you are saying makes no sense. I have owned a 240 before with both a sr20det and a ka-t swap. I was into the whole JDM fanboy shit and didn't care which was more expensive as long as I could say I had a Japanese turbo'd engine just like F & F. They have just as much aftermarket n/a and FI parts for ka just as much as sr. It was also cheaper turboing a ka then buying a sr redtop/black for 1800-2500+shipping. I basically bought the same exact parts for my ka as was in a stock SR and trust me, a used ka engine with 170 compression across the board was 150 bucks. Then I bought a t25, sr 370cc injectors, etc etc etc and all, it cost me around 1000 bucks for a ka-t that put just as much hp as a sr. A used ka is actually more reliable b/c it didn't start off being FI, it was NA, so it didn't have the stress like the sr did. I actually ran 13's in my ka-t at I BELIEVE 12 psi.. I was pushing it that day..

Oh, and you will get smoked though.. 2600lbs car (not stripped) vs a 3300 lbs (I believe) car

This is what I thought. The N/A SR swap was way off in left field for me.

man this thread is like a foreign language to me, but it is better than 90% of the other race threads keep it up guys lol.

Rofl noob.. random numbers/letters for engine codes >>> cubic inches and carburetors

It's funny because my dad has been into cars and still is the original owner of his 69 Goat and 73 Sprint.. I don't know shit about American cars though (except recent Mustangs and maybe some LS1 here and there). I never got into cars until I was older and I just happened to hop into the import scene with my friends. Wish I knew more!

What do you mean a 240 is going to be runnin on 7psi? 7psi is stock for a t25 and I think its 13 psi is the most it can handle w/o it blowing. A stock 240 is actually 2600 lbs. I am pretty sure the sr is actually a bit heavier then the ka, but not by much.. Don't quote me on that though

Yeah, it is pretty much pointless to get the NA sr swap seeing as the cams in the 91-94 ka is pretty damned good making the NA ka just as good if not better then a NA sr. I hate mags like Super Street that say the ka is not a good engine saying that it was a poorly made engine..

Thanks man on correcting me on the boost level. The boost I was refering to was the highest people recommend up to. Over 14 psi is useless.

A stock 240 is actually around 2700 lbs. And the Sr is actually lighter than the KA. The block of the SR is made out of aluminum where as the Ka is made out of iron.

The only problem I had with the KA was it's not a revver (sp?). The SR with some retainers and springs will rev to just about anywhere you want (ok, not anywhere). The KA needs extensive work to do that (although I have seen 8000 rpm ka's). I could see an N/A SR swap for a high revving N/A application.

I wouldn't want to build a NA KA/SR.. Way to expensive and you can swap a better high revving NA motor instead. I read about a build that this company is doing to where you send in your ka and they send it back to you. You pay 5,000 and it comes back with around 250 hp+. I would much rather throw that 5 at a better motor/project. If you had the money, it would be a cool thing getting a NA KA/SR to high hp, but I don't think any of us has that kind of cash to get 100 extra hp..

Hm, my 240 weighed in right around 2600lbs when I weighed it at a weighing station for shits n giggles. You are probably right about the SR being more, so thanks for correcting me there. I thought the KA was made out of aluminum too, I guess i was wrong

if its just a stock sr20 240, an si w/ i,h,e should handle it fine. if its boosted, may be a close race. also depends on the body style. is a s13? s14?

lol, what do you mean if its boosted? noone would put a NA sr into a s13/14.. It would still beat a si regardless of whether it has i/h/e b/c the si is not going to get past 225 na w/o some major work.. The s13 is 2600-700 lbs and pushes out around 225 on stock boost w/o a lot of different mods and some decent tuning w/ a SAFC II..

After reading 4 pages of posts, I decided to chime in. I have an 07 FG2 and 91 240sx with a blacktop sr20det and s13 front end (sil-80).

Stock for stock......fg2 (197 hp) and sr20 (205 hp), the sr20 is quicker
Once modded.......most fg2 only reach 205 whp N/A.
The same amount of money added to a sr20 will create much greater gains through a FMIC, downpipe, and boost controller.

My sil-80 is pushing 320 whp with an s15 turbo upgrade and other goodies. I don't think my fg2 will even come close.......but it's reliable.

well if you say stock for stock, then didn't the USDM 240s all come n/a and sr20det JDM? anyways its really dumb to compare the costs to mod each of the cars because a) 240 is old and parts are cheaper for that reason and b) it comes boosted so of course it is going to be cheaper to mod... now turbo both and what would the outcome be? (assuming it is not an AJP kit that breaks down )

anyways i want one of those 240s myself and put in a nice set up for my weekend car, that or a hatchback civic, but the money is the problem

edit: aren't the sr20s made for a RWD platform??

The one in the US used Ka24e and ka24de motors.

The Sr20s are made in 3 forms. FWD, RWD and AWD.. The 240s and some other cars like the infiniti g20 got the RWD. The FWD went into sentras, 200sx. And the AWD was offered to the Pulsar.

Wow, you're pushing 320whp on a t28 turbo? That is pretty damned amazing. You are right about the sr being 205 hp, but that is w/o intercooler and other essential upgrades. Especially living down south (LA) you need extra cooling. You will eventually get to 225 hp with the essential upgrades you'll need to make the sr run smoothly and reliably.

[hawjdude]

i think u misunderstood me on what i said, u should be laughing at yourself, its basic knowledge that a sr20 stock has a t28 turbo. boosted means more boost than stock. buddy, u got to get out there and race more if ur gonna contradict me on what im saying. first off, i've raced a 240 with a sr20 w/ front mount intercooler, boosted more than stock, bov, full turbo back, and piggyback tune and i did beat him about a car length. this was also with two passengers, one being about 270 pounds. so overall, i would have spanked him if it was just me in the car. then again, there are so many things u can do to an sr20, so it just depends. also, what is it with this hp comparison thing. si only 197 compared to so and so, so it'll lose. i've beaten this 240 already whom should have more hp, also, have beaten stock sti, boosted wrx, stock evos, modded srt4s, modded 05 mustang gt's, modded vw, etc. all whom should have more hp. just get out there guys and find out for yourself.

My goodness I'm gonna have to call your BS. When I had the stock T25 on my sr, at 14 psi I was putting a hurtin' on Sti's (stock ones, from a roll). If you beat an SR swapped 240 that upped the boost to 14 I promise you he had zero intent on racing you. SR swapped S13's with only bolt ons and DR's run 13 flats or better on a consistent basis while trapping about 105-106. An Si WILL need FI to get to that level.

thanks, thought it was only RWD and then i started hearing ppl do it to FWD platforms and i was like wtf?

Rofl, you should be laughing at yourself. A s13 sr20det has a t25 turbo stock. The s15 has a t28 stock. I have never heard of anyone saying boosted in the definition you have said, meaning "more then stock boost". When people say boosted, it usually means that the engine is NA and they put a turbo on there. I also guarantee you, that guy must have the shittiest tune ever, the shittiest sr swap and the guy had to have been a retard driving to have lost to you in your Si. Even the damned facts prove that the 240 is going to spank the Si left and right. The SR s13 traps 13's regularly.

I am going to have to call bullshit on you and please get out to the track more. Nobody in this forum can possibly say they can beat a sr'd s13 on a i/h/e si.

Quick facts:
2006-7 Honda Civic Si=3300+ lbs
1991-94 240sx 2600-2700 lbs

Power:
Sr'd s13 with decent tuning and some nice mods (bov fmic exhaust etc etc)=225 hp+ depending on your tuning and how much you are boosting
Honda Civic Si=197 hp, possibly 225 hp w/ i/h/e

Even if the Si has the same exact hp as the 240, the 240 will win b/c of the huge weight diff. The 240 is also RWD so it will win on the track too

The Si will never will w/o FI

Nice try for making me lookin stupid when you are the noob here.
