another newbie question

Post by **rom** » Sat Mar 01, 2003 12:39 pm

I'm getting a 240sx and an sr20 soon. so now I'm doing research on the performance upgrades. I want to know what upgrades I should get first. and what necesary parts I should get before getting a bigger turbo in the future. what parts do you use? and what brands are better than others. and don't ***** at me for asking stupid questions because i tryed the search and didn't find what i was looking for. if it helps i'm want to build street car and my horepower goals are at about 350-400. thanks for your time.

everyone new to the enigine always wants 350-400 horse power. If you are new to turbo cars i would first set more modest goals. 350-400 horse power requires a lot of work.

As far as first basic mods, everyone in here seems to go: exaust, intake, engine mounts, Front mount inter cooler (FMIC), hot pipe, BOV, boost controlor, and then after all of that they start raising the boost.

My goal is a drifting 300 WHP will little to know lag, need it for autoX too. Maybe 350 with some cams and Port and Polish.

350-400rwhp ... hmm. Do you realize what it takes to get there reliably? Do you even know how fast that would make a 240?

Reasonable questions. A 300rwhp 240 is capable of mid-12 second passes all night long. 350-400rwhp 240 is capable of 11s, possibly 10s if you get some gas (race gas not nitrous) in there with some tire. At 400rwhp you will break stuff, things include, halfshafts, rear ends, clutches, gearboxes, etc. Even if the motor can hold the power. The drivetrain still has to put up with the brunt. OEM rear ends are dying left and right w/ 290 ft.lbs. of torque to the rear. Theres another grand to spend.

Not to discourage you. I'm just trying to inform you of the kinds of things you will face.

Blitz Intercoolers seem to work best on the Silvias.

Walbro 255lph pump will feed your motor. If not a 315 T Rex pump from Vortech will.

For boost under 1.5 bar I'd suggest a Greddy Profec B. If you plan to run over that then get a Blitz SBC iD.

Look to cams and other modifications to give you power rather than boost. This will help to save life on your motor and your turbo.

Upgrade the radiator and get an oil cooler. This too will add life to the motor and turbo.

Adequate fuel is your first priority.

tai i think 350 with no lag is tough to do with a stock block

if u did a stroker kit and over bore a lil it would be easyer i think bigger turbo+ more boost = more lag

Im sorry but you guys that are talking about, "I want 350wrhp" have no clue what the hell your talking about or what your getting into. Have you ever driven a 300 hp car? My old mans camaro put 260 to the wheels and ran 12's. When you stomp the gas getting on the freeway the tires will not hook up, 255's. Honestly 300rwhp on a 240 would not be driveable, and not fun, 250 maybee, anything more than that would only go in a straight line. How many people on here have a 300rwhp 240? anyone? they are out there somewhere, ka's as well.

My blacktops goin in next week, honestly in not trying to be a **** but think about what 300rwhp is, I know you see cars with 400 and 600 hp, thoes are made for it, my sohc 240 dynoes at 114 hp. great running engine with few mods, all the sohc run that and you guys now how well the 240 already goes with the ka, not bad. add even 100 hp to that, your gona **** your pants. In excited to hit 250 with my SR. and im gona dyno it, 300 in the magic number everyone everyone wants, but seriously think about it. you guys are crazy.

I drove a 650hp viper, can we say excessive.

hey whatever floats your boat man... I still am going to hit 300rwhp.......... with a big t28 upgrade....can't wait for that. And I will stop there, after you hit that number you have to upgrade so much and it gets costly. Mid 12's are OK FOR ME

I currently have a blacktop going into my 95 240sx with Sparco seats and c/f hood to lighten the body even more...can't wait, cant wait.

My friend (who actually got me hooked on the whole 240 thing) dynoed SR'd '91 240 in Dallas about 4 months ago and he put down 293hp and 317tq to the wheels. I have driven his car multiple times (and so has my wife) and I can tell you that even 293hp is enough to light up Kumho Supra 712's sized 225/50 ZR16 in third gear if you stomp it. We went down to houston the other day and raced at HRP and he ran consistent 13.1's at roughly 107-109mph. And that was with a slipping clutch and tires that were on the wearbars. I would be more than happy if I could even get 250hp to the ground, 300 is just nuts-o.

BTW: He just ordered the CTC turbo kit and with the specs on the stuff he ordered he should hit 400hp EASY. He also got cams, valve springs and rocker arm stoppers to beef up the valvetrain a bit. He has an SDS standalone system, 75lb/hr injectors, a pretty big FMIC and 3" exhaust from the O2 elbow back. His current setup consists of the aforementioned stuff and a T3/04 turbo running 16 pounds with full boost kicking in at 3900rpm. I dunno the exact specs, but he is moving up to a T3/04S with the CTC kit and that is substantially bigger.

Hell yea SDS, good to know there are others out there! What psi was he running when he put down the 293?

Post by **240_Keyy** » Sat Mar 01, 2003 12:39 pm

He was at 16psi

All I want is 12 sec quarter times. I ahve hit 14.78 and I won't sacrifce reliablity on my new car so the 240 will become my racer. 300 hp I dont care if its 650hp as long as i hit 12'sif it can be done on 275hp thats where I will stop. i just want to smoke a few mustangs and comaros. show them that a import can run quick times too. then maybe if I can still afford it the shoot for 11's

Post by **hopesfallhxc** » Sat Mar 01, 2003 12:39 pm

i would think a more realistic goal that is takeing a bone stock 240 and makeing it into a stock sr20det would be around 250 h/p. but then again some of us only want more...

Post by **SigmaNIN** » Sat Mar 01, 2003 12:39 pm

i have a q for all u ppl that think 300hp is crazy

the stock s15 has 270-280 hp at the crank???how hard would it be to get 300whp from that?????????

300 is alot for ppl who havent driven 300whp before its fast but it no some crazy hp number that noone can reach. and it wouldnt be to back street wish. if im not mistaken a t3/to4 should do ok for about that

god damn civics use t3/t04

Post by **Samabra** » Sat Mar 01, 2003 12:39 pm

Hey 240_Kevy are you talking about avery? I think I'm in line to get ahold of his turbo, I just have to remind him. Those specs are pretty impressive. Chris

Post by **240_Keyy** » Sat Mar 01, 2003 12:39 pm

Yeah Chris, I am talkin about Avery. Jesus dude, you are one lucky mofo. Since you have to use his "custom" downpipe, can I have your 3"dp for my SR? I might give you some dollars for it if you want... shoot me an e-mail or something.

Yes, 280 at the crank, about 240 at the wheels tho..if not a little less. Im just sayin most dont understand what 300rwhp will do or is capable of.

And I never said no one can reach it.. Its very easy to reach, especially with a trubo. s*** a t28 can get you there.

And your right, god damn civics. ha ha

lol aite man i was just venting that day didnt mean to be a azz about it.

Post by **tool34684** » Sat Mar 01, 2003 12:39 pm

i have a 69' gto which dynos 350 at the wheels with a small block 400. not that impressive for the motor espicaly since the car is heavy as crap. but it does hual ***, I used to drive it every day for about a year with no problems, now its sitting and waiting untill i get the 240 done so i can start to work on it again. 300 in a 240 would be crazy fast but you only go as fast as press the pedal down. i agree with you guys warning these newbies becuse most likely they are 16 never owned a fast car before(not making fun of them) and dont realize the maintnace and time that goes with it. along with the responsibility. but if thier like most of us, once they taste 250hp they will just want more.

Post by **MarketGarden** » Sat Mar 01, 2003 12:39 pm

I know what you guys are talking about. I just ment that I want to get all the hp i can get out of the stock s13 or s14 turbo will all the bolt ons, witch id assume would be close to 300hp CRANK. And can any tell me a shop that does the SR swap in the LA area. Thanks again for your help guys.
