Hi, it´s my first post and i want to start with some questions about my built .

Here is what i got:

Y5 block
Y5 Pistons
Y5 Tranny
Y8 Head (Ported and polish)
Y8 Headers and 2.5" pipe
Skunk 2 Admision
Skunk 2 Throttle Body
Y8 Cam
Another "Hot" Cam but i believe its for Z6 because the motor makes a click click sound.
AEM Cam Gear
P72 stock ECU

What you think about this guys?
Should i look for good specs from this?

Sorry for my English

 

I'd drop the Y5 transmission and look for a Y8. Also unless you plan on chipping the P72 (if it's OBD1) I'd look for something that is chippable.

 

Thanks bro, im looking for a y8 tranny and the P72 its OBD2A.

chipped ecu and obd1 harness right?

 

How is this engine even running with this ecu? Thats crazy. Did you even ask the previous owner all the details on this build? How sure are you that the ecu is obd2a?

 

The engine run pretty good but i feel likes the engine needs something.

The ECU its OBD2A because i running a 96 - 98 civic harness whitout a jumper.

 

So I take it you didn't ask the previous owner details on the engine frankenstein, great....

 

The built is mine, the car was stock when i bought it.

The car is a 99 civic HX and the stock harness its OBD2A, the P72 ECU plugs whitout problem but obviously runs very bad.

Now im running a 96 - 98 civic Harness whit vtec conversion n_n

 

So from running good to running very bad...........

chipped ecu will have to do since you can't make up your mind.

I'm not sure why you're being quiet about those cams but k.....

 

Sorry Bro. Lets start again

1.- When i got the car its was stock (Every Stock) 99 civic HX, the stock harness its a OBD2A.

2.- I bought the P72 ECU, test the ECU connection, plugs right (Becasue the Stock Harness its OBD2A and the ECU too) but obviously the car runs very bad.

3.- Made the built like the post description whit the P72 ECU and a "HOT CAM" but the engine makes a click sound, take a Y8 cam, put it in and the click sound its gone.

4.- The engine runs very good but i feel its need something more.

5.- Im looking for a chippeable ecu n_n.

 

What hp were you expecting to gain from using a p72 anyways, "hot cam" doesn't really explain much to me.

D16y8 isn't gonna much performance if you don't do something big with it, and what you're doing isnt big at all. Not to mention this motor is only able to rev up to 8k so if you're hitting that 9k expect something to go.
