Man!!! finally i got my car running. @ first i thought it was my wiring...but turned out it was the tps sensor not getting proper power. After messing around with the tps sensor she fired right up every time. @ first it idle @ around 2000rpm and then went down to 1200- 1300rpm. I can bring the idle donw to around 800rpm but it kinda rough (like the 1200-1300rpm better....sound meaner... ). Also, if i pluged the maf sensor in then she would die on me....and so i cut the black(ground) wire and connected it to the engine- ground and it work fine. The biggest problem that i had is that my temp sensor gauge inside the car rock sky high(almost near the H)....but my engine is not hot at all!!!!! guess i might have to replace or clean the temp-sensor....and put the after-market in. Hadn't taken her out yet because i still had to do the shiftlink...and probably had to figure out how to wire all the a/t input sensors wires. Just finished put the down-pipe....catless and exhaust in and she sound sweet!!!!! hadn't putting the side-mount intercooler in yet cause i am still debating whether should i wait and but the fimc or not. I played with the throttle a little bit and it went very smooth all the way to 4000rpm and then it kinda choke out on me....i thought it might be the maf but then i remembered that it had the neutral-swicth sensor Oh, btw, i found out that the ngk spark plug pfr5g-11 working fine on the rb20det...i hadn't re-gap it yet (maybe i don't had to). just can't wait to finish mounting the intercooler and the shiftlink so i can take her on the road.

Thanks, today after got home from work i finished working on the shiftlink and so i decided to take it out for a little test despite the fact that i hadn't connect the sidemount intercooler and the engine a/t control input signal...and let me tell you....she ran like she was pulling the 18-wheelers!!!!! one second she pull hard all the way to 3000rpm and then sputter and the next second she just crawling up to speed but @ about 3000-3500rpm she began to sputter!!!! this is running on 1st and 2nd gear only. i guess maybe b'cause the intercooler isn't connect and the a/t input signals or maybe the maf and then again it might be the tps sensor causing it not to accellerate smoothly. oh well, guess i will had to figure it out the hard way. Anyway, to answer to your question why did i chose to do the automatic.....well, before owning an automatic i owned an 5-speed and always love the 5-speed...but let me tell you, i had experience racing with an automatic on the freeway and it's seen to me that the automatic is down-shift more quicker than the 5-speed and it can redline more quicker if you modify it right (like my nephew's sr20det-auto RHD...came straight from japan and it can redline every gear)....but the main reason is because i just got tired of the 5-speed. If you lived in Dallas, Texas then you will know what i am talking about (traffic jam)

Yeah,Makes sense to have auto if you have to sit in traffic! Nice to see someone not doing what everyone else is doing by gettin a 5spd or doing a 5spd swap! +1 to you!
