****98 Civic Coupe (JDM B18C Boosted Sputtering / Idle Issues Help!*****
Hi guys I have a 1998 Honda Civic SI coupe with a JDM b18c swap boosted. About2 weeks ago I noticed the car started to sputter and bog down. I went here on the forums and I searched up what my issue might be. Here is the list of things I have already done:
1) Ignition wires checked and replaced with new NGK's
2)Spark Plugs removed and replaced with new NGK's
3) I have an MSD External Coil Ignition. Replaced my Cap, Rotor, and External MSD coil all brand new.
4) Checked my Fuel pump. Primes fine at start up.
5) Compression Tested 200 across all 4 cylinders.
6) My Edelbrock intake is off the car at the moment since i need to change my intake and exhaust gaskets. I removed the throttle body and have cleaned it up looking like new and also the inside of the manifold has also been thoroughly cleaned out.
Just a quick thing I would like to add in when I removed my intake manifold my fuel rail was still attached with the injectors on it and I noticed that the first 3 injectors starting from the left we're saturated in fuel BUT the last on on the right which I guess is cylinder 1 the injector looked very clean. I have not checked the TPS, MAP sensor or the distributor itsself yet. Any help would greatly be appreciated as I have not driven the car for almost 1 month now trying to figure this out.

Almost 200 views and not a single comment cmon guys someone's gotta have some kind of idea. I really wanna get this fixed so I can move on with painting the car and getting it on the road...
Turbo setup? What is this tuned on? What are your AFRs reading when it starts bogging down? Check timing? Eliminate/rule out that MSD setup as a culprit? Those are what immediately spring to mind. More experienced turbo gurus may have more insight.
For future reference if you have issues with a boosted car you might want to post in the Forced Induction section for faster responses.
