Due to an unfortunate mishap...I was forced to stand around the Boost Logic shop for a couple hours today....

Now this is a beefy driveshaft! It's much thicker than a stocker..


The BL guys tipped me off to lowering the diff down so that I could install the driveshaft. It was alot easier than I thought it'd be. Took about 25min to install the driveshaft. I'm still looking for a TT auto pumpkin to replace rusty

any links or help with polishing my intake?

I got everything pretty much done today except the exhaust. I fired it up and let it warm up for a little while....this is weird the gauge was reading cold for a long time..it wasn't until shortly after I actually started driving down the road, that the temp gauge shot up to halfway, and started working...(it also fluctuated one time while I was driving...it went down then came back up wtf...)

It ran ok, but anytime I'd try to barely give it a little more gas than normal it'd breakup real bad.

Once I pulled into garage I noticed a coolant hose was making a hissing noise so I pulled the radiator cap and the hiss stopped as it let out alot of pressure. I did let it run without the radiator cap for a little while, but I didn't park at an angle to bleed the system so I may need to do that.

The weirdest thing is that I looked under the car and noticed a small puddle of water/coolant and it was right beneath the downpipe outlet...that is not good.

I need to do a leak down, but I dont have the kit to do it.

Here is a video. Let me know what you think of how it's running.

couple other thing's
1.didn't install the walbro fuel pump yet
2.used 1 2jzge knock sensor(supposedly this was ok from what I read on Supraforums)

it could be either ignition or fuel related. That knock sensor is questionable, but if it has been done then it might not be ignition. See if installing that fuel pump will do the trick and also flush the system with some injector cleaner.

I'll try some injector cleaner, that's a good idea.

Seem's like it's breaking up, but even at low rpm's. Usually people say it break sup at high rpm's.

I know there are people running with the stock sc300 fuel pump out there, and they don't have issues.

I'm thinking I need to find a 1jz knock sensor or maybe the ignitor is bad. The coils do not have any cracks in them, and I just changed the plugs to NGK 6097 gapped to .030 so we'll see if that does anything since the 1jz are gap sensitive from what I read.

Here's what I've done so far..I got these ideas off the Supraforums 1jz tech section

1.Wrapped coils with electrical tape
2.Regapped Plugs to .026(stock is .028 and anything over that is too much)
3.Routed Map sensor vac line directly to intake mnaifold bypassing the filter is usually connects to at the intake
4.fuel cleaner
5.ECU caps look ok, dont see any leakage

Try using 1" diameter heat shrink on the coils instead of electrical tape. The tape will become brittle over time and unravel.

RyanV

I definitely plan on it.

Here's an update-

One of my heater hoses was leaking and making a leak that looked like coolant was coming out of the exhaust. I fixed that

Changing plugs made no diff
Electrical tape on the coils made no diff
Moving MAP sensor vac source made no diff

I'm really starting to suspect that the 2jzge knock sensor from a 1995 is not working with 1992 1jzgte ECU(makes sense right??)

Anyone have a spare 1jz knock sensor?

StiCk3

iTrader: (5)

it could also be the actual MAP sensor itself. Have you unplugged it and seen if the engine runs differently without it?

also i just found out that the SC3 fuel pump and 1JZ fuel pump are both the same so that shouldn't cause any probs.

I believe the TPS out of adjustment will also cause this

I will look into this as well.

Thanks guys

hey if you need anything to test let me know. I have a couple of the parts that are just sitting there waiting on my harness so you can use them to test.

that knock sensor was not off a black sc300 was it
