Alright, I'm back into buissiness turboing my 93 laser 2.0 DOHC, I got all the parts I need and I'm installing them as I go. First question: Instead of drilling into my oil pan or dropping it and putting on a turbo one, do you guys think I could just hook the return to the dipstick tube? (If it's an acceptable return then I would rig up a y pipe for it so I could still have the dipstick) if not then where else can tap the return line to? I got my water lines all hooked up and ready to go, they're going to the throttle body, (they'll get a good supply of water from there right?), and the feed line is going to go to the banjo on the head, so right now I just need to find a way to rig up the return, I already got the IC an BOV in place, here's a link to my thread with all the pics of my current progress, James.
 
The link didn't show up. Why are you trying to stay away from droping the oil pan, you just have to unbolt the downpipe, which needs to be changed anyway, and than you will have full acess to the oil pan, just remove the bolts, there will be a little prying involved to break the seal. Running it into the dipstick hole is just asking for a major oil leak, there is quite a bit of oil that flows thru that drain, i would highly recomend just running it to the pan. Also are you planning on installing a knock sensor in this thing? If not than your motor isn't going to last very long at all with the stock n/a pistons, and nothing to retard the timing with you are getting knock. Make sure that you hook up the water lines to the turbo also, the 14b won't last to long without the watercooling. You have read about the rewire process correct, it is fairly easy. You will also need to get a resistor pack from a turbo car, to match the injectors that you are using (450's or 390's). Which injectors are you using. are you using the turbo throttle body, your upper intercooler pipe will not connect to the n/a tb. Change that fuel pump too. The n/a fpr will work with boost just fine, and might actually be a good thing due to the fact that it makes the fuel pressure than the turbo regulator (to compensate for the higher compression.
 
ok, here's the link

I'm posting in the newbie section because that forum is deader than a CRX ricer at a DSM shootout and I needed to have an active conversation rather than waiting a couple days for a response.

yeah, I know all that, I have a turbo ECU etc. etc., I'm doing the conversion in steps pretty much, this would encourage others to do the swap as well, so far I have the SMIC, LIC pipe, UIC pipe, BOV/Hardpipe installed in the car, and I'm actually using a 13g just to be a bit more on the safe side, I cleaned out some extra power steering lines and hooked them up to the water lines on the turbo, they'll reach the throttle body but will that be sufficient enough? I know I can drill a hole in the oilpan, I just want to be able to revert this thing back to stock if I ever need to, I was thinking about getting a 1990 oil filter housing and setting up an external oil cooler and just run the lines through the turbo, but that's my last choice right now, I will probably just mark the holes for the return line on the oilpan, drop it and drill it, my return linebroke at the flex section, so I was thinking of just brazing it, would that hold? Now, I was also thinking of selling the 90 ECU and getting a SAFC, I'm using 450cc injectors anyhow so I would need to tune it, I have a datalogger now, I just need the cradle I think, I was going to install a knock sensor but I was thinking of finding another way to know how much knock there was, I am going to run it at 5 psi so I hope there wouldn't be that much knock present.
 
Just because the forum is slow doesn't mean that this topic belongs here. I'm locking this as opposed to deleting it though so you can copy the info and paste it into the other thread. :nono:
