I have my engine torn down to fix a spun bearing, along with a pile of bearing fragments, I find these guys in my oil pan. I've been looking all over to find where they broke off from. They are magnetic, so they're either steel or part of the cast iron block. They're pretty thick chunks, I...

I'm slowly working the bugs out of my car. My car still runs extremely rich after a hard acceleration coming to a stop.

When should you replace the na fuel pressure regulator? Is there a point that the na fpr will fail with multiple pumps and high boost? I'm mostly wondering why replace the fpr, is it so you can stretch out the limits of your injectors? Please explain, I'm thoroughly confused on the issue

Hi all, So, I'd like to turbocharge my NA soon and I want to start gathering parts. My goals (on a motor with 160,000KM, well maintained and still going strong) are: 1. to gain as much power as possible on stock compression (for now) 2. build the car in such a way that if I decide I want more...

MK3 R154 Retainer length. Hey everyone, I have read 3 detailed R154 threads including shern's swap from Clublexus. Has anyone come up with a definite length for a 95 5-Speed swap to the R154? I know the auto/R154 is usually "4.25" inches. If someone can get me a length I'm in the process of...

Hey guys, There has been a page made on Facebook just recently by a few members off mkivsupra.net Its mainly about NA and NA-t supras but its worth a look for all NA-t owners and people running NA thinking of going NA-t. The main reason for its set up was to help each other out with...

While driving, the yellow oil warning light came on and immediately car starts running very rough. I start to hear a hissing sound and stop the car as soon as I could. Checked the oil dipstick, and unfortunately it was dry. I took off the radiator cap, and there was a lot of brown gunky stuff on...

Hello all, I want to order a new turbo, injectors and fuel pump. Any of you can suggest a good place to buy without getting ripped off and paying an arm and a leg ? Also, what would you recommend (part number) for 1200cc or higher injectors and a drop in fuel pump that will support big...

Hey guys, I ordered my ID1000CC injectors before I purchased my FSM kit. My id's are 1000cc TT so its 14mm, and the rail fits 11mm. I have a buddy at a shop that does fuel rails said he can drill it out to 14mm for about half the price of the hats. Should i chance it or just buy the 11mm hats...

I've been searching but all the info relate to mk3s.. Has any mk4 replaced their #2 knock sensor and harness? Consensus is that the wiring goes bad before the sensor actually does and the starter needs to be removed... But that's on mk3s.. How hard is the job on Mkiv NAs? Pls chime in..
