I was looking at the puny size of the throttle body on my pooey 96 1.5 sohc accent, and thought hmmm, maybe i can improve it. So i pulled it off and started porting. the goal was cheap as free, like everything on this car.
Whilst i was porting I walked by one of my failed projects in the shop...a 91 240sx that was to rotted out to fix. I noticed the throttle body was considerably larger then mine. So I immedialty stopped wasting my time porting, unfortuatly 2 hours in, and pulled off teh 240 throttle body.
The damn thing almost bolted on! All i had to do was ream out the holes a little inward, lengthen the throttle cable, glue on the tps, which by the way fits perfetly on the 240 throttel plate axle, port the intake manifold to meet the throttle body so there isnt a lip, remove teh studs from the intake manifold, and after a trip to canadian tire for some longer hex bolts, Voila I had a fully functioning huge throttle body! for the intake i used the section the fit onto the 240sx throttle body, which happened to have the fitting for the IAC valve, and is the perfect length, cut off two pieces of the orignal intake for an adpter for the MAF to the much larger 240 intake, and slapped on a shitty cone filter my buddy had.
I can definatly feel the gain and i highly recomend this as it was very simply and cost me 3$ for epoxy and bolts. Ill try and get pics soon!
the first is for size comparision...it was difficult to get a good pic cause i took the pics after i was done. but the 240 tb is waaaaaaaaay bigger.
the second is of the finished installation and intake...looks stock save for the cone air filter, Im sure the stock intake would stil fit if someone so desired.
Ya I could do that no prob. Im not sure about the gas mileage as of yet Ive only had it on for 3 days now...In theory it shouldn't be any worse if you stay out of the throttle, but who the hell stays out of the throttle! Ill let you guys know about the fuel mileage in a week...Ill also try and tear it all apart agian so i can make a good DIY article.
its seems noticeable, and it cost me nothing...To be fair it is difficult to gauge beacause the throttle response is so dramatically different. Partial throttle at first was difficult to modulate, but after 10 min I became used to it. If i were to venture an educated guess I would say there should be approximatly an 8-10% gain in horsepower.
So to answer the question directly yes the gain is noticeable, but its still by no means a car i would call fast.
one more question before i start to try this. the nissan has two cables coming into it. one is trottle and one is something else i guess. the one on my hyundai has only one.also how did u manage the air intake?
