my sr20 problem

[dave87rx7]

my 89 s13 with a s13 sr20det rwd is pouring out white smoke and has a strong smell of gas. Also the car has trouble running and has a boost leak. this car was handed to me after my uncle died cuz it was his car. i assumed that it was the head gasket because he had a spare sr head. so after i found that i took it to get ported & polished and the had bc springs and retainers put in. that was back in the spring the cars been parked up since he died i had it towed to my house and its been tarpped up since. i took the tarp off today to play with it a lil bit and started to think maybe its not the head gasket ????????????????? he also had a top feed fuel rail with injectors in it soooooooooo maybe it has a bad injector? idk but im getting ready to buy a Nissan head gasket kit to drop the new head on but if its something dumb that might be a easy fix i rather do that . like i said i have a huge boost leak going to my inter cooler. by huge i mean the exhaust manifold melted a nice size hold in a rubber hose coming off my turbo idk if that has something to do with this or not. im really learning as im going but any info would help at this point thanks

Sorry about your uncle passing away. The hole in the hose might have something to do with it. You need to find out what size fuel injectors are being used. White smoke that smells like fuel might mean that the car needs to be ECU tuned for the injectors you are using. Check the ECU to see if it has been chipped for the injectors. If the car has been sitting and was his project he probably was going to get some kind of engine management for his setup.

the injectors are stock . when i got the car it came with all kinds of goodies the top feed injectors are one of many. i hand them tested they all work but how and i find out what size they are?

Ok then yeah you could have an injector that is stuck open. Take a screw driver and listen to see if the injectors are clicking.

If they aren't marked then you are going to have to take it to an injector place and they can tell you what size they are. Sr injectors can come in all kind of sizes and colors. 370cc stock. Aftermarket 480,550,600,740,850,1000,1600cc's.

do u think it could be a bed fuel pressure regulator? im just trying to figure every thing it could be before i jump to a H.G.

Moved this to RWD SR and deleted your duplicate thread.

First fix the hole in the rubber tube - this will cause fueling issues and many other testing procedures you try will give incorrect results unless it is fixed. Anything will do temporarily like duct tape - but don't drive using duct tape.

Second, replacing a head gasket is a hell of a job. Personally I hate it. Lot's of places where inexperience can really mess you up and kill the engine. If it ain't bad, don't fix it.

I would buy or borrow an engine cylinder compression tester and follow the instructions (unplug ignitor, pull fuel pump fuse, have throttle wide open when cranking, use a full battery to get good, consistent cranking). Post your results here.

You may want to make 100% sure you can get the engine running right with 100% stock fuel system. Verify you have stock MAF, stock ECU and stock injectors. Throwing upgraded items (MAF/ECU/injectors) in the mix with the rest stock will make it very hard to troubleshoot.

f*** i put a q45 maf on it i guess i need to pull that off and go stock............... but today i pulled all the spark plugs they were all black and covered in gas so i killed the fuel pump and cranked it with the plugs out. it was just pouring gas out like a volcano then died out a bit but the one cylinder was still spraying gas out ?????????? i read some where on here that someone had the same problem so they put new plugs in because they felt the old plug weren't strong enough to burn the gas off and it worked for him. but it didn't work for me sooooooo i unplugged the fuel pump and cranked it again to get the pressure out of the fuel lines . i think ill pull the fuel rail next because the rings look a lil bad. but the car still wont start and run longer then 10sec........... idk

Sounds to me like it is running super rich. What Fuel Pressure Regulator is on it? I would definitely send the injectors to Deatschwerks for testing and also get a tune done by JWT once you know what you have.

It's definitely a stock regulator
