ToyoII

Found it from looking through old pics . . .

So nearly done, but there are a few things I forgot / didn't take a photo of as I was undoing it. So first thing is this silver cable . . . does anyone know where it goes or what it does? It wasn't connected to anything when I removed the engine and I forgot to investigate while engine was out. Second thing is these boost pipes, where do they go? I know one goes to a nozzel on the side of the plenum but the other . . . I have no idea. Thanks in advance.

Didn't realize though that it would give me access to the top bell-housing bolts though, defiantly would make my life easier as they were a pain to remove, so was dreading trying to put them back in. :blink:

Fear not, I have done the EGR delete, I just did it straight after taking the pic, was waiting till someone mentioned that lol :laugh:

No, my new o2 sensors arrived today, so will be fitted before engine is reinstalled :blush: Thanks for your help though, always nice to get another opinion. Would have been nice though if there was just am L and an R on them.

Just to check, because hopefully the engines going back in tomorrow, weather permitting, so Itook a photo, and can people confirm this, because it's alot easier to swap over when the engines out :blink: [/img]

Great, that's the way I fitted them, but it's nice to be sure. :balloon:

Hello, I've just fitted my new aftermarket exhaust downpipes, but I'm not too sure which way round they go, they have no left or right markings. So do they fit so they swing inwards towards the transmission or outwards towards the sills? Thanks.

I have bought some aftermarket downpipes, so wanted to just re-use my lambda sensors as there is nothing wrong with them, but as its only £80 delivered for some new AMS ones I might do that and sell on my old ones.

They're good I would like to reuse them, I've been told a blow torch can help, is this true?

My o2 sensors are being a right pain is there any trick I can use to remove them easier? Thanks in advance, Dave.

Progress so far . . .

Looks great, well done!!!

*946ml*

Thanks, Looks like I'll need to buy 3 bottles of 946mm to do a complete oil change then.

Ok, great, I guess the next question is, how much will I need?

On the way with changing my turbo's and was just wondering if anyone knew what transmission oil to use? As I might as well change it while I'm at it. Is 75W-90 Semi Synthetic alright? Thanks in advance :laugh:

Well I've got the feeling I'm going to be postponing this till next week due to the weather turning. But I'll defiantly let you know how it's going. No doubt I'll have a few more questions soon enough.

I pretty sure it will go past 14psi on the gauge (may not though) . . . but the gauge isn't the most accurate :tongue_smilie: As long as my aftermarket gauge / garage gauge says I'm doing 12psi ish I'm happy.

Yes I'll admit its rare, but I'm happy with just uprating the actuators and I can add one later. Also there not the cheapest and I know people with them and they just end up turning them up and up, getting the bug and wanting more power. May not break the car but it just adds more wear which I want to avoid, hence only a marginal increase that I was looking for. So in conclusion . . . it appears I'm going to be running about 12psi. Which from what other people say there running or have run is not all that extreme - denfinatly won't "let him blow his engine up and then he will know your all correct": "MarkDerby - with a remap u can up the boost to 13/14psi ish", "bigh - I was running 14 psi with boost jets and upgraded chip, on the dyno it maxed out at 370bhp" "vodkashots - 14 to 16 on stock is what ive heard countless times." "Yowser - With a remapped ECU , 14psi is a safe maximum raised boost level with Stock Injectors." "jaylox - i used to run 16psi boost on stock tubs, remapped ecu" "z32bolt - you could run a max of 16 psi on stock injectors and a chipped ecu" So thanks for all the info guys, it's kind of put my mind at rest. I'm starting the turbo swap on Tuesday so nice to know I'm not going to spend however long and it all be for nothing. :blush:

You don't get an answer, if you don't ask the question. :stupid:

That's why I'm on this forum . . . for the great guys on here that are in the know. My stock gauge at the moment is getting to just over 3/4. But I have a knackered turbo and am pretty sure it was closer to the +7x100mmHg than the 3/4 mark when working fully. But I know the stock gauges aren't amazing, just an indicator really. I did buy the actuators from Z1 Motorsport. Which are defiantly in the know too, and I'm pretty sure they wouldn't sell me something that they say can be used with a stock setup, that would blow my engine to bits. Not exactly a great way too get a good rep as a company. So I'm happy with my decision. My engine may be 21 years old but it's only done 69k miles and in my opinion that is a more of a contributing factor in the life of an engine than age. With boost controllers, to be honest, I don't trust them. It only takes one software glitch and you could be putting 20+psi though your engine (bang). Feel safer with good old fashioned mech eng.

Ok as I understand . . . over the stock 7.5 psi the boost solenoids will give a little extra boost, by restricting the actuator, to 9psi. Thus a 17% increase. So am I right in saying that I will likely get an approximate increase of 17% over my new 10 psi actuator as well (assuming no ECU errors), therefore about 11.7psi of actual boost pressure?

Ha now I've gone from thinking my actuators are set too high, to thinking there set too low. Hmm well my gut instinct was to go for 10psi just because I didn't want to go crazy, just to get a little extra umph. I've had other cars running at higher without issues but I want this to be my longest lasting and last Z/car I'll ever own. I.e money is no object to keep this car going.

To many people saying to many different things, I asked JKM to set my actuator to 10psi. If what Yowser is saying is true and "The stock turbo's run 9psi each (or about 7psi in safety mode)." then 10psi is only a fractional increase over stock.
