I met a guy with this swap in his 89 DX hatchback. It seems almost like a ZC setup. The block # shows D series but the head is 2 cams so basically DOHC. It is fuel injected b/c it has the PGMFI on the intake manifold. The guy has a junkyard turbo setup on it and he just bought my nitrous system and is running a 50 shot on it. He laid down a 9.1 on the 1/8th without the nos and only 7psi. Now it's at 12psi and the NOS. He's taking it to the track today to see how it does. What the hell is this Motor???

 

the d16a1 first gen integra motor, zc, d16a8 are all pretty much the same. I think the a8 is from europe or australia.

 

Don't know where a D16A8 comes from, but...
1986-87 Integra D16A1 113HP/99TQ
1988-89 Integra D16A3 118HP/103TQ

 

d16a8 and 9 is the DOHC ZC....from the UK.....one has a cat one does not.....thats why the numbers are different..

Almost the same motor as the 88-89 teg...
