we put a 1.6 d16 into a dx crx and used the dx intake manifold and now it won't rev past 3500rpms. I did a search and found nothing. Using everything stock dx with the obvisious exception of the engine itself. Any ideas?

 

sounds like u have issues good luck on finding out on it keep us posted

 

If youre not throwing and engine codes (CEL) if not the it sounds like you have an air leak? well did you reuse the intake manifold gasket? if you did you might have a break in it somewhere.....if you didnt. Did you scrape the gasket surface area good? if not then thats youre problem?

 

what codes is it throwing? 4 or 9 i bet

No way, I don't think he knew that.

But it sounds like it is in limbo/limp mode. Like the dude above me said, you didnt give much detail about your problem but is it throwing any codes?

 

not throwing any codes at all. Used the same gasket but it looked good. I'll try a new gasket. Thanks for the feed back

 

A air leak will usually cause the car to idel high not lower the idel.

 

the distributor is different from the si to the dx. which dizzy did you use? it is your crank position sensor (code 4) that is causing your car to stop at 3500 rpms. You will either need to change the dizzy to the dx or wire it in properly. I'm betting that is your problem. i don't think it has anything to do with the intake manifold.

 

already using the dx dizzy, and no codes are thrown and dx ecu. Tried using An integra ecu with same results. 89 teg

 

Why didn't you just convert it to mpfi?

thank you captain obvious!

Sounds like intake air temperature problem. make sure you have the clips plugged in right, there are a few spots on the back side of the intake where the same clips can fit...

 

Reverse your throttle position sensor wires. The DX one turns backwards.

 

wasn't my choice, did it for a friend and he was trying to avoid the rewiring.

 

still using the dx throttle postion sensor, so it shouldn't need to be reversed, right? THE only thing that we used from the si engine is the long block. Used the dx throttle body, intake, etc

Tell him to trust me, it's soooooo easy to do. Just that it takes a bit long to solder all the connections. One of the simplest things to do on a DX. He'll really benefit it rather than use a dx DPFI. Here's one of the best write-ups I've ever seen (& personally used).
