hi i have a 98 civic hatchback the d16y7 motor blew a head gasket and whoever did the previous head gasket tightened the head down to much and it stripped the threads in the block. i picked up a D17A2 motor for free from a local shop n have no idea on anything bout the motor. my qeustion is it would be a straight up swap into my 98 hatch? from jus looking at the engine the only difference from the d17 to the d16 is the thermostat housing is on the front. plz help this is my daily driver!!!!!!!!!!!!

Its not anywhere near a bolt in affair. From what I recal it was about the same amount of effort to install a K-series. It will be far easier and cheaper to just drop in another D16Y7.

I wouldnt touch a D17A2 with a 10' pole. Just get another Y7 bro, itll probably be cheaper too.

The D17A2 comes from 2001-2005 Civics. There is not a lot of potentials for the D17A2. It's like the K series mount of the D series. If I were you i'd sell it and just buy another swap. Don't want to mess around with the D17A2. You can spend thousands for internal work and only get about 10-20hp gain.So you mine as well Supercharge it or Turbo the thing for real HP gain.
I mean I drive a 2005 Civic Ex SE. I just like the whole body of the EM2. But as the motor, it's not that great. Just get a D16Y7 or do a mini me swap and add a Vtec head.

Here's the specs for the D17A2

Displacement (cc): 1668
Power (bhp@rpm): 127 @ 6,300 rpm
Torque (ft/lbs@rpm): 114 @ 4,400 rpm
Compression Ratio: 9.9:1
Bore (mm): 75
Stroke (mm): 94.4
Cam Design: SOHC
Valve Train: VTEC

Oh and I've heard Vtec engages around 2.8k RPM. Still have to look for that.

I'll also let you know, this engine (D17A2) is badged as a VTEC engine, but it functions as a VTEC-E. I tore this engine down and to my surprise only had 2 cam lobes on the intake side, and only 2 intake rocker arms. I've been searching about this, and if you look around at the right sites, you'll be notified it functions as a VTEC-E, and not the performance oriented VTEC.

VTEC-E basically operates as 3 valves per cylinder until VTEC engages and it is ran on 4 valves per cylinder, but does not operate the cams hotter (cams opening more).

I know, it's a horrible fact :[.
