My 1990 240sx sr20 build

[sicride]

croiks, where is Richboro? and where are you going to school? I goto school in Johnstown, PA- live in Pittsburgh area.

Looks like some really high quality work done here. If you're close I might have to inquire about hiring you to do some work for me lol. You really seem to know what you're talking about, gluck with the build. I'm sure a lot of us can learn a thing or two from you.

I go to wilkes university, ME major, in Northeastern PA. And live by philly.

Wilkes Univ.. Is that in Wilksbarre (sp?)? I'm gonna have to say you're a little far away lol.

My grandparents live out there in Tioga County/Mansfield PA. Quaint area, beautiful, too quiet. If that is where abouts you're at.

I picked up this clutch for my original sr20det plans but no longer need it since im not using that motor. Its brand new, make an offer if you need one.

the picture didnt work i might be interested in the clutch can you send me a pic to [email protected]? thanks.

Beat you to the painting of the support, it just takes a while to get pics on here. As for the weight issue, its not really even an issue. Yes the RB weighs more, but you need to understand that it is longer, i dont know your educational background, but its easily understood with a background in statics and dynamics. Also the additional weight is also in the transmission, the transmission is close to the center of the chassis which reduces its effect on handling since the additional weight is applied to all 4 spindles rather than the front 2. A complete KA24de weighs in at 540lbs on the scale, and the Rb25det weighs in at 720lbs. This is a 180lb difference. Yes, some of this 180lbs is putting more weight down on the front end, but like i said before its not like your putting 180lbs on the front bumper, the additional weight is spread from the radiator support back to past the shifter. It would take math and measuring to figure out exact numbers but it is obviously an insignificant number. Just think, gas weight an est 6lbs, with 15 gallons of gas in your tank, your adding 90lbs to the rear of the car then your on empty and taking 90lbs out of the rear of the car but the handling still is very close to that of the full tank of gas. Or how about when you ride with a passenger, the average male weighs somewhere in the are of 180-225lbs. Does your car handle awful when you have a passenger, no. Vehicles are designed to have verying weights in them, thats why they mark on you door sill the allowable changes in weight. Hey i dunno about you but id rather have the 300+ Hp with a resonable stock RB than the 130some of a reasonable stock KA. People can argue the handling issue all they want but it doesnt get them anywhere becuase the swap is still going to be done, and its still not going to make a noticeable effect in the handing aspect of the car. Even if it was a huge difference, suspension tuning would allow the weight to be compensated for. No built car has the same weight bias as a 100% OEM car, just due to the fact that people take off things to lighten it, change the tires and wheel setup, add turbos and other various items that all add and remove weight. This whole weight arguement has been done too many times, the biggest variable in handling with out question is SUSPENSION, you can ask any chassis builder and you will always get the same answer. Here is a set of shocks I have, axis racing, penske built, nothing will effect handling more than a set of good shocks like these but youll pay ($1500 for these 2 shocks pictured obviously they are not for a 240 but they are real racing shock absorbers, the most influential aspect of handling)

You sort of forgot one thing though. All things being equal, you'll add more polar inertia to the car which means it will ever so slightly turn into corners slightly slower because the car will want to resist rotating. This is because the straight 6 is longer, and neglecting weight differences that's more weight hanging farther out in front of the front suspension, trying to resist a change in direction by the front wheels. However once the car settles into the corner it's all the same, so the fact that the 6 sounds a lot better (my opinion) and you'll have more tuning freedom you shouldn't really care .

EDIT And BTW, that is one bada$$ 450r you got there.

Really nice progress so far.. I'm watching

[HurryupandrunS13]

I love the stance of that car with those wheels!!! Definately keep us posted. If those rims are still available let me know, one on my 240 had been curbed like a mofo

Well I picked up my motor from JDM Engine Depot last thursday. Its a clean *** motor, probably one of the cleanest Ive seen. Heres some pics of it. As of right now It is in and about 80% wired up but I cant finish it till I get a break from school. Heres some pics.



They didnt have any stock shifters so he gave me this one for free!

Looks brand new inside

hint: take shifter off before installing motor...

you probably already know this, but just making sure

Ha, yea i no. And the motor is already in so, ya, i knew that.

[homeslicej2]

Nice. Hope you get some pics up soon.

[gaehrings13]

God damn that ****ing motor is clean. I wish I could find a ka24de like that. I would be so happy if I bought a motor and it came like that. THATS AWESOME LOL!!!

[WoDan23]

woah i live about 5 minutes from wilkes university....i wanna see your project in person! and hey ill buy those rims from you maybe when your done if your willing to sell....thats cool an RB locally....never seen one in the area!
