    oil cooler kit for around 150$ with thermostat and gauge ports!

    That does seem like a cheap solution, but be aware that you are trusting the livelihood of your engine to a super cheap, cast aluminum sandwich adapter and a CX Racing cooler. If that adapter fails or if the cheap ebay cooler springs a leak you could earn yourself a full engine rebuild. At that...

    7mgte rebuild - Need Advice on Gaskets/Hoses

    Another plug for Rock Auto, especially for gasket kits and other small, or non-OEM parts. I'm not sure why anyone would hate on Rock Auto. They carry a variety of brands (some premium, some cheap, plenty in between) and offer plenty of parts you can't get through the dealer or which are...

    What did you do to your supra today? Pics

    Drove mine last night after installing the cheap ranger driveshaft bearing. Driveshaft feels fine, but my intermittent starting problem is still present. Codes 14 and 43. It only fails to start. Cranks good, but doesn't start. it will pop start just fine. Looks like I need to start a thread on...

    How to Replace a MKIII Driveshaft Carrier Bearing for $50

    I'll give the cheap Ranger bearing a try and if it fails quickly I'll re-evaluate either Yota OEM or really leaning on Frank at DSS to finish the two piece aluminum he started for me. So far, the 6062 appears to be the right size. There is much less bushing material than the OEM style and the...

    How to Replace a MKIII Driveshaft Carrier Bearing for $50

    Just bought a 6062 from Advance Auto for $25 picked up at my local store. I'll see if I can get some time tomorrow to install and report back!

    7mgte rebuild - Need Advice on Gaskets/Hoses

    This shows the difference in the Toyota OEM kit http://www.cygnusx1.net/Supra/Library/EPC/291420/catalog.aspx?F=1103&P=2 At a quick glance it looks like the bottom end kit includes these extras: Rear Main seal housing gasket Turbo Elbow Timing cover upper seal rear timing cover gasket Water...

    7mgte rebuild - Need Advice on Gaskets/Hoses

    I'd go with a bargain gasket set but use OEM for the exhaust, throttle body, and a couple other big ones. Maybe some good info for you here: http://www.yotamd.com/toyota/mk3_supra/bhg.html Sent from my XT1060 using Tapatalk

    High compression high RPM 7M-GE build

    Neat to see all the machine work. Keep the pics and info coming! Sent from my XT1060 using Tapatalk

    Bet youve never seen this.

    OEM gasket, clean the block, mill the head and change that oil a handful of times. I've always had good luck that way. Sent from my XT1060 using Tapatalk

    Painting gauge needles

    You need to paint the backs and it will require removal. It can be a pain to realign them. I've done it about ten times and its still kinda a pain. The paint should not affect the needle performance significantly. My recommendation would be to buy real aftermarket gauges and install them in...

    What did you do to your supra today? Pics

    Pi, I thought the same at first. However, there doesn't appear to be a trouble code for either G1 or G2 of the CPS. 12 and 13 deal with NE and G. Additionally, 14 points to ignition circuit. A major part of the ignition circuit is the CPS, correct? You're much more familiar with the inner...

    What did you do to your supra today? Pics

    After literally years of unconfirmed suspicion, a seal replacement attempt, multiple resistance tests, and a few failure to start episodes I can finally confirm my CPS is bad. G1 coil is reading 200k ohms or more. In trying to find the source of my starting problem I also tested the igniter...

    Here we go again--spun bearing

    Keep us updated on the results! I'm curious if the moly coated gears really up the idle pressure a noticeable amount. Of course, the oil cooler and adapter will increase your oil pressure as well so it'll be hard to tell exactly how much the pump is contributing. Good luck!

    Gauge wiring question

    You want a 12V constant in addition to the switched 12V wiring. I made a make-shift terminal block out of a 10 pin connector set for both accessory and constant 12V to feed my gauges and anything else that will need 12V. You can get the signal from a wire under your dash (above your feet), in...

    Re-tapping the exhaust threads

    Ok a couple things: 1. The 29/64 drill bit is larger than your old one, however, that's not the concern. The drill bit would need to be larger than the outer diameter of the tap/helicoil you used (assumed to be M10). I'm not confident it would be. If the drill bit cannot fully clean out your...

    Re-tapping the exhaust threads

    Something doesn't sound right here. The DM kit needs a 29/64 drill bit for the 7/16 inserts. If you used a 13/32 bit on the existing installation you won't have much material to work with going to a 29/64 bit. Not to mention a 13/32 looks like the size used for an M10x1.5 insert and the DM kit...

    Block/head engineering question

    Came here to sway just that. The mechanics of flow don't have much of an affect compared to the difference in surface area in the above situations. I think the idea with engine cooling jacket design is to get the most surface area of water jacket possible as close to the heat source as possible...

    Shimming the bypass spring on the oil pump

    Haha, no doubt Ian has me (and virtually anyone else here) beat on experience. However, I've never been one to lay back and let "because I said so" be the backbone of my learning. If he's right, then awesome, show me some proof. Surely manufacturers spec lighter oils for a reason. If using...

    Shimming the bypass spring on the oil pump

    Ian, in the case of a 7M, where is the extra flow coming from? Simply showing more pressure does not equate to more flow. Don't misunderstand me, an increase in pressure can mean an increase in flow if you have a variable flow pump. However, a car engine like the 7M (and other belt-driven oil...
