Found the limits of 2LTE! Shade tree repairs question.... (3 Viewers)

Nice, good call! Having a truck apart is like being off work. The longer someone or something is not working the less likely it’s ever going to again.


For camping I have a new plan.

In an effort to not pop my motor and to bring all my toys, dogs and people camping across BC. I need more secure storage space but! don’t want to tow a small house around through the mountain passes. I been searching and collecting parts to build something like this.

Have a Trailer axle and papers
Need Service truck cabinets
And Roof top tent

A couple things I would do different than this one:

The tent frame would be higher at least 6,6 so I can walk under it and the bears have to stand on their tip toes.

The tent should have the second room curtains under it that go to the ground. If more room is needed for people have a second tent on the truck?

And wider tire track to match or near my track width, possibly slip a fly fishing boat in between the cabinets.

Picked up some cheap but fun temporary wheels. Will actually end up my son's car. Bit of a project, but runs decent. 2006 mini cooper s Rallye. Always thought of these as pos BMW, but after some reading and driving, I have some respect for it....

Thanks! Yeah, lots of used parts around for these cars. Lots were produced which means lots to scavenge from. That appeals to me.

Replaced strut mounts and front control arm bushings on the sling shot this weekend. Requires removing bumper and subframe. Pinch bolt in knuckle broke off and even easy out didn't work. Had to drill out until almost nothing was there, peel out. New bolts and anti-sieze on every thing now.

This job reminds me of the front axle job on a solid axle cruiser. Sort of an "initiation right", haha. I feel like I know the car well now.

Got the kid to help with this job. Took most of the weekend which he wasn't thrilled about. I gave him the alternate option of taking to BMW and spending a few grand, lol!

I need to do my 60 knuckles. Thanks for bringing that up.

looks like so much fun... barrel of laughs.

Snow in forecast is motivating me to get my ass in gear and work on cruiser again.... I took for granted snow was never a big deal before. Now it's a show stopper getting out my neighborhood (single access via steep hill).

Funny thing. Mini Cooper S mileage is supposed to be good. But I drive all my cars like I stole them. Mini has been getting the same city mpg as my cruiser! Maybe it has a sensor issue, I don't know. Gotta learn how use one of those new fangled code reader things I guess.... But I suspect it's not an issue. Again, took the cruiser for granted: Twice the weight, but same fuel economy as a Mini.

New (used) head is ready to go on. Confirmed it's the late model 2LTE one which is improved over original. Valve clearances shimmed within 1thou of middle of Toyota spec! I put in all new seals and bearings. Head seems to have had little use, as the valves/seats were mint and looked to have been recently ground. But whoever removed glow plugs broke one off. That was a real PITA to deal with.

Was trying to do pistons yesterday, but couldn't get the damn oil pan off yet. Sealant I last used appears to have been nearly permanent. Good thing I have a spare oil pan, as this one might not survive removal. Ugh.

I was doing some research the other day thinking of building a square tube style log manifold when I read something about four-cylinder engines with firing order 1-3-4-2:
Will have cylinder 1 ending its expansion stroke and opening its exhaust valve while cylinder 2 still has its exhaust valve open and vice versa.

In an undivided exhaust manifold, this pressure pulse from cylinder exhaust blowdown event is much more likely to contaminate the paired cylinder with high pressure exhaust gas. this hurts the other cylinders ability to breathe properly and obviously efficiency.



I wonder if in a cast factory log style manifold the long runners of cylinder 1 and 4 don’t breathe as well? Say if during a push but the egt probe being right in front of cylinder 2 and 3 doesn’t show the true temperature of cylinders 1 and 4 being much further away. Like say a post turbo egt probe reads 200 degrees less just a couple inches further away.

And a divided manifold

Just some rambling thoughts..

While working on a project and clearing metal shavings with my air chuck i incidentally discovered the stock undivided 3b manifold is not as inefficient as I might have guessed.

 

[stevebradford]

Built a simple undivided log turbo manifold and not surprisingly it doesn’t vent as well as the stock NA manifold. I will still run it because I love how it hugs the engine keeps things tight and clean.

Cool. That for your 40?

I've been thinking I might have to steal your hood scoop method for my 60 intake. No plans to intercool it, but I would like something better than the skinny hose inside the fender.

 

[stevebradford]

Yeah that manifold is for my bj42. I have always thought that nook centre hood could scoop up massive air. And without changing the sexy brick sh!thouse lines of the 40 series.

Sounds like a great plan. I was definitively pulling a negative pressure in my air box with the turbo 3b and stock setup at 2 7/8 inch, I imagine I was always pulling some negative pressure. Upsizing to 3 1/2 intake pipe pre turbo was definitely worth doing. More free air, less heat and happier motor.

Yeah I upped the tube size on the 40. Up to 4" I think .

Noticeably quicker to build boost, just haven't gotten around to doing it to the 60 yet.

I've debated the same thing many times over... I thought it would make a great source of cooler air.

One concern I've had is that I've submerged the front of the hood in water in the past. Were I to do that again with a hood scoop there it would be bye bye engine. Similarly in '96, when I got stuck in the snow, the snow was usually at least to the top of the hood. Although, I don't think that the snow would be sucked in very well... it's hard to say for sure.

Since I have a Safari Snorkel sitting on the shelf, I'll probably go that route before doing a stealth hood scoop.

 

[seapotato]

With the diesel trucks, the intake is a hose snaked through the side apron up to that front area. So, the location isn't really changing a lot.

But a 2' long snaky small diameter hose before the filter is terrible for air flow.

In my case, I'm thinking basically a funnel that aims it at the intake of the filter box, (which I'll increase in size as well.)

Wouldn't be a sealed connection because of the hood opening and closing , just ballpark to let more air in than that s***ty little hose.

The one in my 40. Smidge larger than stock, noticeable difference on first drive.

@stevebradford How's this going? Running yet?

 

[stevebradford]

No not yet. There’s no shop on the island that rebuilds turbos is there? I damaged the compressor wheel trying to clock it. The centre was oxidized to the compressor housing and I used a little too much persuasion to free it!

Just buy an aftermarket compressor. I *believe* they're balanced independent of the shaft and turbine. But there is a place in lower mainland that can check balance for you. Nut is reverse thread.

Intercooler is there for the chunks if it isn't...

I mixed and matched a few different bits into a turbo in the past. Even rebuilt one with new bearings...it didn't explode
