I am probably going to be starting an sr20det swap into a 240sx. I want in the end to have 340-360 at the wheels or enough to run about a mid 11 with a trap around 120.

What are the strength limits of the stock, crank, rods, pistons, block? So I know what needs to be replaced to hold that level of power.

you can do that on stock internals, so long as you don't plan on going any higher.

i dont think your gonna be able to run a mid 11 with only 350wHP...

well I think it would. a z06 vette dynos at 350-360 at the wheels stock. it runs a 117+ trap speed. it takes a 117-119 trap speed to run a mid 11. so if 360 can move a vette fast enough for a mid-high 11 I think that is enough to move a lighter 240sx to a mid 11. how much do you think it would take to run a mid 11 with a limited slip and slicks.

dont fall into the trap of comparing a natural aspirated car to a turbo or forced induction car's 1/4 times.

there is a lot that comes into play...your not running a 11 on a stock turbo, so it will depend on what turbo you have, cams, etc... turbo lag, while that turbo is spooling will come into play.

its hard to say...ive seen 357hp cars run 12.2's-12.5's (240's w/ SR), ive seen 450 HP cars run mid 11's to low 11's...

Its all about boost...when your making boost, at what rpm, how much boost, etc etc etc.

basically it will run a mid 11 come hell or high water. I can always spray to help get off the line and to spool the turbo.

basically sounds like my eventual goal with the car im trying to put together. but luckily i work for a shop responsible for building/tuning many 900+hp sub 9 second cars:)

if all else fails ill throw a narrowed 9" rear end and some 10.5" slicks under the damn thing

Jay's car (psi240sx) only run's mid 12's, and he has like 360 or so whp with a KA24DE (T).

His traps are 118mph. But he also has no traction. So it really is going to depend on your suspension and tire setup as well.

If you want a quick 1/4 mile car..... why go and buy a 240?

just curious....

take care,nils

hope he's not doing it just to have an 11 second car....No matter how much HP that thing will have it will still loose to the supra's, rx7's, and dsm's at the track:D

but doing it because you like 240's and the SR motor is another thing. its fun, but isnt the 'best' choice when building a drag car....I do drag my car, but i like the originality of it (even know SR's are getting played out now), its fun to have a 240 head to head with those other cars, just isnt the cheapest or the easiest way to do things : )

Why don't you buy an F-Body?

or a CRX w/ a b18+turbo and NOSSSSSSSSSSSSSSS

lol....you mean NAWZ =P

if you ain't got no NAWWWWWZZZZZZZZZ, you ain't ready to roll with the big dawgs foo. : ) Leave it to a supra owner to know the correct pronunciation of NAAAAAAAAWWWZZZ.

lol... I wouldnt put NOS on my car if my life depended on it..... NOS makes up for poor build up & tuning.. like a bodybuilder taking steroids..

The cool thing about Jay's car, is it looks like a stock 240SX with rims, yet he's running 118mph trap's! Even the motor looks stock, except for huge round spinny thing hanging off the side of the exhaust manifold

I have to disagree with that one. Nitrous can be a very good compliment to tuning when used correctly. It does narrow the tuning window, but does allow you to produce more power. There are cars w/ 14:1 compression running 150 shots, and 30psi of boost. Its not for everyone, and not all everyday applications can be benefited, but with the proper tuning it can be a blessing.

I recently read an article by Buschler about how he was the first user of nitrous in the import scene, and became its Biggest Hater, and disliked it more than anyone else on the circut, and swore against it.....Recently he has changed his opinion 180 degrees, and now is the biggest supported of nitrous on properly tuned applications.

Its a real good article, and a good magazine, if any of you pick up Drag Sport Magazing....0 rice included in every issue : D

If I wanted just a quarter mile car I'd get a mustang or a turbo buick. I want a car that is more an all around car. I won't put drag suspension or anything like that on it.

But it will see the strip and racing my friends and their dsms and wrx's. I wouldn't do any other car because I don't want to put alot of money into it and I hate fwd cars.

What do you consider a lot of money? Most people don't consider putting a SR20 powered 240 into the 11s chump change. : )

I am not denying its potential and use, specially in drag racing applications.

To me it is just temporary power for street cars, not like a turbo, where it is on your car and it will always work.. you have to go and fill a bottle up all the time and you are limited to its use... ****.. might aswell go and run your car on alcohol :o

Why not build your car so that you wont need NOS, I dont have NOS and I spank 99% of the cars on the streets, including ones with NOS.

just an opinion.

nils

Yeah, but a basketball sized turbo looks good on a supra engine. Its bigger than a SR20. : )

Again...im a drag racer:D , so all the post i make seem to have that effecting my thoughts, lol....so i wasnt even taking streetability into it, or using nitrous on your street car, i was refering just high hp drag racing applications.

Guess i gotta stop doing that : )

well I'm thinking

car 1000-1500sr20det 2200exhaust 300fuel pump 120downpipe 100clutch 320hoses etc. 100air filter 50

so 4400 for a running 240 with a sr20det

so for 11s

turbo 1500injectors 500intercooler 300blow off 155limited slip 500slicks 600

so about 8 thousand to run 11s

I'm probably forgetting something so remind me. also I can get most of the stuff wholesale and most prices listed are retail. so help me out here.

with 8,000 dollars you could run 12s.

engine/fuel management?($250-1000)radiator/cooling system?(200-600)weight reduction?(free-$50)gauges (so you can moderate your investment so u dont blow up)?($50-500)Z32 MAFS?(100-170)Rollcage?$2000 (required for 11's)id consider a larger fuel rail (50-250)Most people would do the headgasket before 11's, but it would hold it for a while i think.

ill try to think of more.

jesse

I knew about engine management electronics I forgot to add those.

so

afc 320

local track is an ihra track so I don't need a cage until 11.49.

what kind of 60ft, and front 1/8 does he have? you are aware also that if u spin your trap speed will go up a bit

There is a thread about his latest run. Check it out: http://www.nissaninfiniticlub....=1612

His 60' was 2.192 and his 1/8th was [email protected].
