Couple Problems

[VectorVA]

I just swapped in my sr20det that I bought from Phase2. I used the wiring guide from HeavyThrottle to wire it up and I also followed their directions for start up regarding the oil light. I disconnected the wires going to the distributor and cranked it a couple times till the oil light went out. Then I fired the engine up.

After the engine got warm smoke started to come from the exhaust manifold & turbo. I’m assuming that it was the new gaskets, but I’m not sure.

Also, when I rev it up in neutral it didnt generate any boost. Could there be a boost leak? When I take my foot of the gas and let the engine return to idle, it bogs a little and almost dies. Not sure what the problem is, I think it might be vac. hose related so this is the way I setup the hoses.

The small nipple on the top of the TB splits and goes to my boost gauge and my FPR. The large nipple on the top of the TB Splits and goes to my Greddy Type-RS BOV and to my cannister. The small nipple on the bottom of my TB goes to my canister. Is everything hooked up right?

Also, I noticed when I was using the HT wiring guide to wire up the wires that go to the gauge cluster I noticed several black wires, assumed they were all ground and grouped them all together. Was this correct?

bump... i would also like to know more about this.. i plan on cranking my SR 20 for the first time either tommorow or sunday.....

A new problem, I tried to back it out of the driveway and when I press the clutch in I hear a vibrating or rubbing sound, and when I try to put it into gear, it grinds a little but goes in gear. I was able to back it up and move it forward but I’m worried to take it out for a drive.

***I took it for a test run and the thing spools up great, no leaks. I guess it just wont build boost while free reving. Also, the droopy idle that occurs when you let off the gas is apparently normal so I’m not worried. The only problem I am having is with the sound the clutch makes when you press it all the way in. It sounds like its the pilot bushing so I’m going to replace it and see what happens. Other than the pilot bushing, everything runs great and its a blast to drive.

that's awesome man, sorry i couldnt help you trouble shoot or anything, ive only been around SR20's for a few months and im almost done w/ my swap now... i plan on going out to get some premium gas today, and putting fluids in there to crank it up...

so in your opinion, or anyone else's..... is there a reason to hook up your boost gauge if it's the first time your cranking it, but you dont plan on moving it?

also, one more question, where did you guys find the torque specs and what bolts did you torque down?? would there be any harm if i cranked the engine w/out torqing the motor/transmission mounts down to spec... what if they were on there tight?

I disconnected the wires going to the distributor ...

SR20DET's don't have distributor. You probably mean CAS.

After the engine got warm smoke started to come from the exhaust manifold & turbo. I’m assuming that it was the new gaskets, but I’m not sure.

Mine smoked a bit too. It's normal.

Also, when I rev it up in neutral it didnt generate any boost. Could there be a boost leak?

You're right, the car won't make boost in nuetral. It needs load.

When I take my foot of the gas and let the engine return to idle, it bogs a little and almost dies.

I'm guessing your BOV is not recirculated. Recirc the BOV, and all will be well.

Bleed your clutch. Adjust your clutch engagement (pedal height). And make sure you have GL-4 transmission fluid and that your transmission has enough fluid in it.

The sound you hear might be your throw out bearing. Did you replace it ?

[VectorVA]

I never disconnected the hydraulics for my clutch. I just unbolted it from the KA transmission and then bolted it onto the SR when it was installed. I did replace the throw-out bearing when I installed the new clutch, however I did not replace the pilot bearing because it looked fine but I think it might have been damaged when my dad and I were wresting the transmission back on. I'm replacing the pilot bearing right now.

I am recirculating the BOV. But the bog happens even when I'm not building boost. I talked to a few people in the area that have SR swaps and they said it’s fairly common. It just drops down to 500rpm right after I take my foot off the gas and then it smoothes out to 800rpm and idles beautifully.

Filled the transmission with 2.5 quarts Redline GL-4.

i cranked my sr 20 last night for the first time... after it settles down, it idles smooth around 800, when i rev it up in neutral while sitting still.....and then let off the gas... it acts the same way. it will drop down to about 500 and rise back up to 800 and return to good idle. What type of exhaust do you have on there right now?? i only have the greddy turbo elbow and greddy downipe on right now....i hope it gets a little bit smoother when i get the rest of the exhaust on... someone told me it might have something to do with the back pressure..??

I'm running a megan 3" downpipe to a catco cat and the apexi n1 dual. It sounds great. The idle still bogs though even with a complete exhaust. Like I said, i think its fairly common.
