    7M oil leak. Looking for references

    Okay, so I've just put a 7M-GTE that's been getting built up over the last 4 years or so bit by bit into my '90. Am I 100% sure of anything that was done 4 years ago? Of course not. Block was taken to a machine shop, and matched for tolerances to the forged pistons I bought for it...

    Possible oil leak sources? Remedy ideas.

    Just wanted to see if anyone has a second opinion on where I could be getting an oil leak. Lots of possibilities, since I just had much of the engine stripped down, but I think that it's the turbo drain. Why "think"? Because I can't actually see the source of oil. I installed an oil...

    Any pointers getting to coolant hose?

    Well, while installing my PTE560cc injectors, I managed to damage the coolant hose that goes from the ISC to the pipe nipple underneath the intake runner to#2. So I obviously need to replace it, since I don't want a coolant leak, but I'm a bit stymied as to how to approach getting to it. If...

    BIC Targa Bars, impressions.

    Well, my BIC Targa bars arrived today, but it wasn't until evening that I was able to give them a good go. (It was raining earlier.) Chassis flex: On a scale of 1 to 10 where 1 is the targa off, windows down, and 10 is my hardtop (Targa roof bolted on is about a 9) I'd give these a solid...

    Theory v. Practice: Wideband sensor location

    Okay, I see lots of pictures of downpipes, turbo elbows and other things with a wideband sensor right next to the stock sensor location. I've read a number of documents that say not to place the sensor right next to the turbo outlet, place more than 15 degrees from horizontal and 10 degrees...

    Piggyback power

    I'm looking at adding a couple of things to my '90 ECU, and was curious as to the best strategy for power. I don't want to overload the fuse to the TCCS, and I'm having some trouble finding power requirements for things. On the other hand, I really want to avoid relying on an otherwise...

    eBay knock-off TRD shift knob

    This Item just arrived in the mail today. It's billed as being a real TRD shift knob, though it came in Momo packaging, which my genuine one did not. The genuine one is on the left, the eBay knock-off on the right. My genuine one is a couple years old, and is shinier (Though I think that it...

    Exhaust recommendations please.

    Okay, I've got 2 Mk3 Supras. One is going to be built with whatever I have that's suitable, the other, I'd like to do as well as I can budget for. I have 1 exhaust that I'm pretty sure that I don't want to keep. Stock elbow, some sort of downpipe that I haven't measured for size, though it's...

    Compression Ratio and target boost.

    Okay, so I'm almost at the stage where it's time to bolt the head on, and I'm getting cold feet about the static compression ratio. The block and head have been milled 0.005" each, so this is about 0.25mm shaved off. I have a 1.4mm MHG on the bench, but I'm thinking that it may not be such a...

    In-car removal of oil pan

    I'm giving up hope of having the new 7M built and installed before the snow flies. As it sits, it's knocking. Pretty sure that it's the rod on #5, though it might be #4. So here's my idea. Slap in new rod bearings so that I can maybe get some seat time in, and get the car around to a few...

    Oil pump line threads / Driftmotion braided hose.

    I'm puzzled. I got a Driftmotion braided SS line for the oil pump tot he block from someone who won't be using it, but it wasn't quite complete. The adapter from the oil pump to the line was missing, and the other adapter wouldn't thread in on either block or oil pump side. The adapter...

    '87 7M-GTE teardown/rebuild.

    Okay, after swapping in a 7M-GTE which had been sitting for an unknown period of time, and had (Surprise surprise) a BHG, got rod knock. Bought another 7M-GTE which had been pulled, and disassembly started for $250, which I was originally just going to swap in. Well, currently I'm glad that I...

    7M build advise please

    Okay, after replacing the clutch last year (ACT stage 3), I got some issues, which seem to fit with a walked crank, or at the very least, rod knock. I've got another 7M-GTE lined up, and should be here before the weekend, which I want to get ready to drop in. In preparation for this, I've...

    Rod knock Qs

    I'm pretty sure that my 7M-GTE has rod knock. Kinda bummed about this, but it is what it is, and I've got decisions to make. I haven't touched bearings in a very long time, and never on a 7M. Not looking forward to doing this, either, but if it's what I've got to do, then it's what I've got...

    Electric fan control idea. Looking for comments.

    Okay, well, I was thinking about electric fans, and of course the problem is, how to control them. I've got an idea for this, and would like some feedback on the idea. I want to build an electric fan controller, which would trigger a relay to provide 12V to a set of electric fans. In my car...

    Boost peaks, then drops.

    Looking for suggestions here. I've got one of the older Turbonetics bolt-ons with a 60-1 compressor on the front of it. Unsure what the A/R is on the hot-side turbine, but I think that it's 0.50. It's got an internal wastegate, connected to a BOSS turbo elbow, and RT downpipe. Good exhaust...

    Clutch job woes.

    Okay, so the clutch started slipping. It happens. Ordered a new one from Driftmotion. No problems so far... Well, then I looked at the garage. No room. At all, and no reasonable way to make room. Then, the post office goes on strike, so the parts get delayed in arriving. Well, they got...

    Toyota Axle Codes

    Since I see the occasional thread about installing a 6 speed in the A70 chassis, I found the following information that I had stored away. The bolded ratios are the ones that already come in an A70 chassis, however, it shoud be possible to use 8" differentials from other models, some of which...

    New Turbo, supporting mods?

    Okay, got a new (used) turbo. Very happy with the deal, but I want to ensure that I'm not going to do anything bad bolting it on. :) It's a Turbonetics bolt-on, internal wastegate, should bolt up to the manifold (with a spacer) and LIPP elbow. Supporting mods (Either installed, or will...

    6.5" speakers in your pre-91 doors

    Okay, I just got my set of MB Quart 6.5" separates, and I'm going to make 'em fit these doors, for sure. I also got a set of Kicker SSMB6 6.5" subwoofers, which I may install instead, if I can get more than 0.3 ft^3 and the requisite mounting depth, and locate the components in kickpanels...
