So I just installed my 3inch downpipe and my coupler from the the 3000 pipe to the throttle body ripped so I got a new one installed. My problem is that around 4k rpm car sounds like its missing/hesitating and I hit fuel cut. It threw a code 12 and 34. I replaced my MAF and the boost is stock. I...

So I just got my walbro 255 in the tank and then I find out my Fuel pump relay is dead. I bypassed the relay because I am going to 12V fuel pump mod soon and was wondering why my car dies if I'm cruising at 3k rpm and I put the clutch in it will die. If I let the RPM's come down in a gear to...

So this problem has been pissing me off for the longest time. Every 3 or four days my car looses about a gallon of coolant. No signs of leaks, etc. I have a gallon of coolant and the rest is tap water in the system. I bleed the system and 4-5 days later the waterfall sound is back. I have no...

So I hooked up my MBC two ways first wast vacume line with a T-fitting straight to where the arrow pointed. The second nipple on the MBC was set to atmosphere. It's only boosted to stock PSI. This is how I have it hooked up now after researching a little bit and it still boosts to stock psi no...

Well when I run my car hard I hear hissing and sizzling where the turbo water line adapter is. I have the SS lines for my turbo water lines. I was wondering if this would cause my car to overheat and lose coolant. I recently did MHG / ARP. There is not a single coolant leek elsewhere, no oil...

so I replaced my front knock sensor and reset tje code. after starting the car up, about 15 seconds later check engine light came on. the weird thing is the check engine light goes away on a warm start up but them comes right back. im guessing its the wiring? all replies are appreciated.

I've broken 3 knock sensors and I've had it! These things get so damn brittle. When it breaks, code 52 shows up and the car runs like shit. Anyone know how to bypass just one knock sensor? I'm going to leave the one behind the starter because that one has never been replaced and it's holding up...

I feel like my car has drive line lag or slack. When I let off the throttle and get back on it really quick, it takes a second, and I feel like everything underneath me move then comes back into the same place and then I start moving. I don't have the turbo manifold support or the intake...

When I drive my car I can hear it tick from the exhaust side. It's not a knock, just a tick tick tick when giving it gas. I did the 2000-3000 rpm test and no knock was present. I checked my manifold studs and one is stripped, all the others seem fine. Also under boost, a squeaking noise begins...

Well I recently did a full swap on my car, complete 7mgte with all new internal HKS MHG, ARP studs. The first time we torqued the head down, we had a stuck valve so we had to pull the head again. Then I got a complete head job done, new valves, seals, etc. I cleaned the MHG with acetone and used...

I finally figured out my starter problem and now the car cranks, has fuel and spark, fire starts and doesn't idle at all. Dies the second you let off the throttle. I even readjusted the timing, took the entire cps, etc. I'm lost, also my gauge cluster doesn't want to work either so that's also...

So I got this motor from drift motion claiming it had only 800 miles on it. It was also said that it had a bhg. Now I was wondering what this looks like to you. The bhg was for sure, but what is that crap on the cylinder walls? Do you think I can clean it off or do I need to take it apart and...

I have an aftermarket water temp gauge which has a 3/8's NPT fitting. I was wondering if I could just re-tap the stock temp sensor housing and use it there. :1zhelp: It is a pain in the ass to find a 3/8's NPT radiator hose adapter plus using the OEM location will look clean. What do you guys...

Hey guys, just picked up a supra and I loved it for the first 5 days and then the motor blew. Here are some pics: I picked up a 7MGTE from drift motion which is now going into my car. Some other problems with the car are the entire gauge cluster not working, I guess I'll...

Hey guys I need some help with my dash. My car is a 5 speed turbo but the dash has a o/d light under the tach, so I'm guessing that the dash is from a auto. My entire dash doesn't work, the only thing that works is the sport suspension, when I switch it back and forth it lights up, everything...
