My friend has a 93 240SX,
He put in a sr20 motor. Stock turbo(7psi), 5 speed. He's not new to shifting, but he's also not the best. Other than swapping in a different motor its basically stock.

How would each of the Camaro's stack up to the 240? From a roll and a stop?

Thanks.

 

the only chance is gonna be that L98 car




from a dig youll pull a car then his turbo will spool up and hell most likely get up next to ya really id say its gonna be a drivers race but u should edge him out in the drag but on a street course/ autocross hes going to spank you pretty good....

 

Dad>You>Brother

As far as the 240, it's hard to say. I've seen swapped cars running 13's and I've seen them running 15's. It's one of those "just run him and see" type of situations. Good Luck!

 

the SR20 is a solid engine built on a very good nissan frame...lightweight and really likes the high RPM's definately gonna be a drivers race imo but i think the 240 has him not by mucch tho

 

wow, that bad huh.
What mods do you think I will have to do to the Iroc to keep with him or beat him(without swaping in a new motor)?Could anyone give me a 1/8 mile time for the 240.

Thanks

 

put in some giggle juice and you'll take him out pretty good. Maybe a shift kit and stall if your using a auto. Better gears like 3.42s or so. Slashing his tires. Make sure your car is well tuned seriously the difference between a good and bad tune is night and day.

 

agree'd....if its an auto id go as far as a 3.73 no bigger then that with maybe a 75 shot (thataway you wont need to adjust any timing) and youll be ready to run him ...again its gonna be all about staying in front...man your going to rip him from the dig no matter what....the x factor will be that turbo spooling up....if u get enough cars on him from the dig then youll be gold...
----------
also what kind of headers are you running on that iroc....if there shorties id definately recomend upgrading to a set of LT's which improve your mid range power....if u do that and get a tune and run a 3.73 rear youll probally get him with that....

im guessing your running shorties but correct me if im wrong...

dude imo a 350 swap is ideal specially for you who has the best handling of all the chassis listed above....your car will out handle both the Z28's and throw a 350 in there youll spank your dad something hard lol....plus there is no changing of anything except the harness and the engine itself everything bolts...including that intake....if u need more info on a swap i can help you plus it wouldnt cost a whole lot

 

What are you talking about? The following is quoted from the Media section.
"The '92 Z/28 comes with a new performance handling package that has optional 36mm front and 23mm rear anti-sway bars, as opposed to the 34mm and 21mm standard bars. This performance package also has stiffer spring rates, and overall it makes for a much more aggressive car that is incredibly stable and feels as if it has an aftermarket suspension kit."

Not to mention that in '92 Chevy changed the process used to seal the body seams that made the body more rigid. That's also in the Media section.

 

ive seen a swapped motor/turboed 240 at the track once. it clicked off a 13.8 at 105mph. never talked to the guy so i dont know how much boost he was running

 

Your right. I bought some Hooker 2055's. By the time I race him Im going to have my intake/plenum/runners ported, a bigger cam, gears, a stall, rocker arms, and a really good tune. And maybe a 75 shot just in case

 

Just for the record, the SR20DET swapped 240's are slow as dog **** on stock boost.

 

Yeah. I don't think it will be anything too spectacular either. Stock SR20DET makes 205hp. 240's aren't that light. You can check out some more info at SR20 Forum - The essential resource for all things Nissan SR20 on the Web - http://www.sr20forum.com.

 

a buddy of mine had a 95 240 with the sr20 red top, he was new to rear wheel drive and ran a 14.3 at the track. later put a boost controler and cat back and put 261 hp 313 tq at the wheels and the 1/4 simulator predicted a 13.0 run. that was at 18 psi. mostly depends upon the driver. a srt-4 with cold air intake, coilpack, wires, and boost controller at 17.5 psi pulled a car on the 240 from a 35 roll. what i say will help you most would be gears i pulled a 3.42 from a v6 and swaped them in place of my 2.73's and made a big difference. i would race him if your cool with it and don't have to hear the other run his mouth over and over about it. also the stock sr20 turbo being the t25 i belive spools up quick but is dead around 6k. so try to do our thing on the low end. good luck, justin.
