Okay. RB25. BONE stock, stock fuel, stock turbo, stock ecu, stock maf. STOCK! The only thing I have upgraded is a FMIC and a Walbro 255 pump. That is all. No AFPR either. Here is what is happening. I go to floor it. Try to burn tires whatever. As SOON as I get just past half throttle I hit what feels like a fuel cut problem! AFR's go from low 11's all the way to lean. Past 18's. I let out of the throttle and then its back to normal driving. The car runs absolutely perfect when driving normal. But as soon as I go past 1/2 throttle I fuel cut. Not a missfire, it completely cuts out. Just out, gone, nothing. Imagine as soon as you go past half throttle, some air gets sucked into the fuel line, the more air, the longer and harder the fuel cut is. The less, and well the less. Sometimes its so minute that I can keep it to the floor and it does fine, after the lean burp, other times its so bad I have to wait a bit for the fuel to come back.. I have tried 3 MAF's, 2 FPR's, 3 Fuel Pumps, wiring the pump straight to the battery, making sure battery terminals were tight, new plugs, no boost leaks, right about 19 vacuum at idle. The car idles flawless, drives flawless, but once I try to go full throttle, it poops out! I have no idea what to check next. Some people have said I have a dirty injector. No. If I have one bad injector i would have almost a missfire, not fuel cut. PLEASE HELP!!!

No. Rpm range doesn't matter. Its more like Throttle position. Which makes me wonder if my tps is bad.

I actually don't have the solenoid. It was removed. But I do think I got my boost thing fixed. My current issue is some weird fuel cut thing. It leans out, like a burp, while in boost. Most of the time while in boost I am in low 11's AFR's. Then I have this little pop where it leans out. And the car loses power for a moment. I have all stock fuel system minus a wlly 255 pump. So I don't see how I am actually not having enough fuel. If anything I would think too much. I am running stock boost. Actually less. I noticed today I can only get 5-6 PSI. I am going to try a different MAF and see if that is a problem. I just don't get it. There is nothing evident for a lack of fuel.

Alright. Looks like it is the WG. I unplugged the boost reference and went to boost it. Once I saw 7psi I let out of the throttle and just drove normal. I didn't want to over boost it ya know. So now I either need a WG remedy that may fix my problem or a new WG.

Hey guys. I know I haven't been on here in FOREVER! But I REALLLLY need help! I had a build thread going on here for my RB25 into my S13 240. Well I finally got it all "done" and drivable. But now I am having issues that make me quite angry. lol. I can't boost the car!?!? I will be driving and when I floor the throttle the turbo spools, the cars sounds happy, and then it pins at 3 psi and sits there. Thats it. No more boost!?!?! I can't figure it out!!! The car is bone stock. Stock MAF, stock ECU all of that. I had an over heating issue but my Tstat was stuck closed so I took it out for the time being. Only once in a while when I go to floor it the car hesitates, almost feels like fuel cut. Then it acts fine and still revs up. But no more than 3PSI of boost. I have checked for leaks, I changed my BOV, I have a 255 fuel pump. New gaskets on the motor. I use premium gas. I just don't know what to do.... PLEASE HELP! And if it is easier for you (or if willing) you can call me at (803) 404-1958 Thank you!

Part 4: Well this was just kind of for kicks. I had the paint so why not see what it would look like lol... yeah... not so much. Primer And now the paint. LOL talk about bright. I don't think she is going to stay this way. I was going to take it to bare metal but I wasn't in the mood for extra work. I'll probably just end up painting it matte black. Before clear. After clear. Yeah, like I said. Probably not going to stay. lol Part 5: UPDATE!!! Well this is what the engine bay now looks like. I think the red could have been cool if the car was going to be a show car. I am going for a car that can't be seen at bight though. Black on black on black lol. And yes, I do know there is still some red peeping through in places. I need to lay one more coat on there. PICS! I did how ever find some MINOR frame rail damage. Not noticeable in the pics and it's not bad at all. But it's there. lol. Motor will be here before NOON tomorrow!!!!! I am so stocked. And it's a perfectly good reason to be late for work! I HAVE to sign for it.... and stare at it.... and ... to..u.ch. it.... ooooooohohohoh. Okay cargasm over Part 6: UPDATE: The baby. Valve covers and cams: And some beauty shots lol. And I be hiding behind my turbo! Part 7: UUUUPPPPDAAATTTEEEEE: Some random pics for your viewing pleasure. One day they shall meet! And I think this just looks bad A! I kept slipping though so I is slightly fuzzy. Part 8: DO WORK! Well I didn't get to wrap the manifold, I couldn't find any black wrap at the Auto store. Luckily we can get it at my work place, and I can get it for cheap lol. Just have to order it. More pictures... Here is a better one of this picture. Not so fuzzy... Power Steering and A/C removed. Just need to get the motor onto the stand so I can get the bracket off, it is supporting the motor at the moment. And just because Part 9: Small Update: I didn't get to do as much as I wanted to tonight because the flywheel bolts are tight as crap. I don't have an air compressor at the moment to use my impact. But the clutch does look good. Yeeeeah Part 10: As promised! Update WITH pictures! OMG WHERE'S MY MOTOR!!!! Found it!!! Then gravity had to jump in. The motor fell! She's okay though. It will still bolt up to the trans! And yeah, I picked this baby up for $60!!!! Hellz ya! Part 11: UPDATE! Gosh darn this one is going to take a while... Well I wanted to do something special for the valve covers, so this is what I came up with. Cleaned up all of the hard lines to the best of my abilities. Felt like getting everything getting nice and clean. So I did some painting ! Then we decided to fix my buddies oil leak. Part 12: Update: I had these gauges when I was going to boost my SVT focus but I didn't because I didn't want to risk my DD. Hence this build thread you are now reading. Wideband Boost Oil Pressure Some goodies I bought today with the money I got for selling a spare turbo I had laying around. Surprisingly the universal pillar pod fits extremely well. Put the dash back in. I didn't bolt it in because of needing to move it around for some wiring. Some test fitting. With the gauges The pod is not mounted yet as I am still wiring and what not. I got some wiring done on the gauges but not all of it. I'll probably be doing more this coming weekend as I work all week at both jobs. But yeah, thats what I did earlier this evening. That is where I am at, at the moment. I am shooting to have the motor back in the car by the end of this calendar year but we shall see how the finances hold out. I have a friend on this forum and said you guys are amazing. I figured I would join, share my stuff and hopefully get some constructive criticism.

This is all copy and pasted from my other Forums. Okay fellas, I figured I would go ahead and start a build thread since I am getting sorta close. The vehicle: 1991 S13 hatch. AKA, Lucile The motor: RB25DET I will try to get pictures up when I get home from work... I have ordered my radiator and I will be ordering my motor swap set on Friday, the 6th. I am uber stoked for this swap. I have pulled out the stock KADE and started to clean the engine bay and beat back the firewall and beat out the trans well to fit this bohemoth. The body of the car needs some love but for the most part, she's pretty clean. Some dents and dings and the rear bumper is beat in from a fender bender. Paint is quite fair though. For now the plans are to have the motor stock, then I will be doing coilovers, then get into the cosmetic stuff. Interior was a little rough so I gutted it out and am ready to replace the carpet, and I will be re-upholstering the door panels and some random crap. Not sure what I am going to do for exterior as yet. I am thinking of vinal wrapping it, but that gets pricey. I love the look though. I will do my best to keep this updated as much as possible. I will get pictures tonight! Part 2: Well here are some starter pics. The day I picked up my baby. I started to pull out the interior. The carpet was a little rough. Started getting the KADE out. I was originally going to build the KADE for monster boost but wanted something different. There is no one in my town with an RB so I figured I'd shoot for the first. And here are the most recent pics. Need some love on the body but I know a guy who is probably one of the best metal workers I have ever seen. Lower Radiator mount is bent from PO's accident. Not terrible but it aggravates me lol. Rear bumper bashed in pretty good. Caused the trunk pan to flex and crumple slightly. So there you have it. Thats where she sits as of right now. I have big plans for her. I hope to at least get the car running and the suspension taken car of before next summer when I move to Charlotte for NTI! Part 3: Yeah baby. Got my mishi today. Like 2 minutes before I got home from work! She's so pretty!
