Driveable Differences: 89-90 vs. 91-94
I know the DOHC is 155bhp, 160ft/lbs and the SOHC is 140bhp, 152ft/lbs, but for a daily driver, will I be able to tell the difference?
Im gonna look at this auto 89 fastback with 151k miles. The only reason Im thinking of getting an auto is because its only $1,150.
If it was a decent DOHC manual, I was gonna keep it NA, but since its a SOHC automatic...Im thinking of swapping.

i have driven an 89 DOHC (it was my girlfriends car that was origanally a sohc but we swapped in the dohc when her timing chain went) and my 90 sohc, and there is an enourmous differance. The DOHC has much much more power. If you are not planning on doing the swap, definatly get the ka24de

I own a 1990 240sx SOHC and I have driven DOHC 240's as well mine is much faster then a DOHC now but I have to admit stock V.S. stock that you will notice some diffrence at around 4000 rpm the DOHC seems to have a little better pep at a higher RPM but off the line there was no difference, but at a higher RPM that's where the DOHC starts to shine and seems to pull a little better. If you are going to buy the SOHC a nice simple HOTSHOT performance header with a 2 3/4 inch exhaust and a HKS cold air intake will easily help you outperform a stock DOHC. If I were you I would buy the cheaper one SOHC and use the money you saved to do an engine with an SR20 or RB25. Either way good luck

I have a 92 DOHC 240 and have a bunch of buddies with SOHC 240s and have raced them numerous times. Everytime we race, I am always plenty far ahead. My one buddy has a 90 240 with Injen CAI, Hotshot header, Apex'i N1 dual cat back, Catco cat, and a bunch of other goodies. He took it to the drag strip and ran 17's consistently. I ran my bone stock 240 and pulled a 16.4 as my best. Usually ran 16.5-16.6 consistently. So a SOHC with some go-fast stuff will not outrun a stock DOHC.

Maybe your friends need to shapen up on the 5 speed driving
I got many modifications done to my 240 now, but even when I didn't before, just with a hotshot header a straight flow magnaflow exhaust system, a HKS cold air intake and a port polished intake, I was taking out stock DOHC 240's all day long. It doesn't take much work to get a SOHC to go faster then a DOHC.
