I have an 87 Turbo and need a new MK3 engine, as I have rod knock and the car struggles to keep idle and blows out black smoke. The car is worthless as it is right now. Does anyone have any suggestions for a couple of good places to get an MK3 turbo engine? I saw that some come with a...

Background: Lexus/550 mod, AFPR, Walbro fuel pump, HKS BOV recirculating, complete 3 inch exhaust from turbo to muffler (TANABE CAT-back). After changing old engine parts and setting the timing my idle issues with missing and sputtering have gone away. Using a wideband oxygen sensor helped...

I set the timing as per the TSRM and it smoothed out my idle but still have the backfire problem between gears, especially between 1st and 2nd. What causes the backfire upon deceleration? (I have the Lexus/550, S-AFC, HKS SSQV BOV, new plugs, new coil packs, new coil pack ground wire. The...

My problem: The car was missing at idle, and also stalling after stopping at a stop sign. I bought an ISC off of a list member, cleaned it and installed it. I also have new spark plugs (it was time) and new coil packs (one was bad). I took off my TPS and cleaned that too. I made sure the...

I looked at the TSRM and it outlines a lot of steps to take out the timing belt. Is this all required -- take out radiator, take off clutch fan assembly, etc. It seems like I can do it without taking the radiator out. It also says no dirt, dust or oil should hit the belt but I see a lot of...

I went to a local airport to an 1/8 mile "flashlight" race and beat: 1- 1987 Mustang GT stock 2- 1990 Lincoln Mark VII with a modified Mustang GT motor 3- 1999 Pontiac Grand Prix Supercharged stock Cars that gave me some trouble 1- 1987 Buick Grand National modified (very close race -...

I know this has been talked about a ton since 2001 and this is not completely technical or about the MK3 but I thought everyone would enjoy it. It seems Toyota may have finally given in. Here is a picture from Road and Track. It is expected to be a V-8. :dunno: Click the link below for...

Thanks for the previous inputs. I purchased a Sears timing gun and was wondering what degree to set the timing to as 10.5 is for the stock spec. I have the Lexus/550 mod with an electronic boost controller. I usually boost to 12 PSI. Is there a range anyone can give me as far as degrees...

My car always had regular (non synthetic) oil and I was wondering if just draining the oil, replacing the filter and adding a synthetic oil like Mobil-1 was OK? Is there anything I need to do like a motor flush? I always thought it was OK to switch over but some say once you have regular oil...

I have a small backfire after deceleration, when shifting between gears and going from a higher RPM to a lower RPM. Anything I can check or a suggestion? Thanks

Anyone know the cause of a 5-speed 7M-GTE stalling after hitting higher RPMs? For example, say a half hour drive on the highway and then winding down the RPMs when approaching a stop sign or stop light? It does not happen all the time but seems to happen the most when going from a high RPM...

Just wondering what my boost controller should have as a vacuum value when the car is idling? It looks like around 16.5 (a little past the 16 hash mark). Is this normal? Why I am asking is the car idles a bit rough (misses). Thanks, Sal
