5.0 supercharged into an LR4?
Quick update: I’ve been looking into the head differences more and more, and I made a small discovery. Originally I thought the valves were identical between the two cyl heads....as it turns out the exhaust valves are the same, but the intake valves are different. Which makes sense as the SC... -
5.0 supercharged into an LR4?
About 100K But, I’ve already bought all the timing chain/head gasket stuff. So even if I buy the RTO, I’ll probably go back through it and rebuild it just to be safe....I’m kinda OCD like that. [emoji28] Sent from my iPhone using Tapatalk Pro -
5.0 supercharged into an LR4?
I’ll keep you guys in the loop as things develop, but I too need to start a timing belt/head gasket update....at that point, I figure I’ll just pull the whole motor, rebuild everything and even put a new TC in, just to be safe. A crate motor would be the best way to do it, but so I’ve it... -
5.0 supercharged into an LR4?
Yeah, I’m kinda going for OEM feel, just more horsepower. Aka, this is my wife’s DD, so everything had better work the way it’s supposed to! Translation, no Check engine light. Truthfully, that’s what’s driving the swap for me. In theory, and I stress the theory part, I should be able to... -
5.0 supercharged into an LR4?
Thanks for the parts source! I was most likely going to use eBay for a donor engine. Although, I’m starting to think I may yank mine out and rebuild it from the ground up....it MAY be cheaper. May being the key word! Although a w low mileage drop in has its appeal as well! Sent from my... -
PWM logic assistance
As I understand it, the fan, even at full lock turns at a different rpm than the engine. This is just due to the crank pulley vs fan pulley diameter difference. Take it one step further, and when the fan isn’t at full lock, which in theory is most of the time, is spinning completely different... -
5.0 supercharged into an LR4?
The pistons are different on the supercharged engine to drop the compression ratio. Unfortunately, just bolting a supercharger on isn’t going to work, it’s kinda got to be a full engine swap....or maybe I’ll rebuild my block with the different pistons and add a supercharger. [emoji848] I may... -
PWM logic assistance
Hey guys! I’m hoping someone in the forums understands how the LR ECU handles PWM signals? Long story short, I’m in the process of swapping to an electric water pump and electric cooling fans. The only real problem I haven’t solved (aside from how to route the serpentine) is how to fool the... -
5.0 supercharged into an LR4?
Yeah, the trans/driveline was my biggest fear, but as far as I can tell, they’re identical! Sent from my iPhone using Tapatalk Pro -
5.0 supercharged into an LR4?
Hello all! Let me kick this particular conversation off with where I’m at. I’ve got a 2010 LR4 with about 170K miles on it. The engine is slightly overdue for all the timing chain fun, but it’s also developing a coolant issue. Before you ask, the water pump and crossover tube are fine... -
IID Tool - RPM fluctuates, hard downshift?
It agree it sounds like you’re having some trans issues. That said, the first thing I’d do before taking it in, is change the trans fluid, trans fluid filter (I recommend the upgraded pan with removable filter), and finally, and this is a BIG one, replace your mechatronic seals. A lot of... -
2012 LR4 HSE Speaker Upgrade
Just FYI, the timing chain isn’t due until 150K miles...hopefully that’ll relieve a little stress....and another quick FYI, I’m at about 157K on mine....but yes, I’m starting to get REALLY nervous. But $4K for the parts alone is A LOT to swallow right now. And the 825W amp...I found on... -
2012 LR4 HSE Speaker Upgrade
Pretty much the same for me too.... the JL audio speakers I’d like to put in there range from $400-$900 per pair....and at 14 (or 17) speakers, that’s getting astronomically pricey. And that doesn’t even factor amps in. When coupled to the fact that I’ve got to do the timing chains, elec... -
2012 LR4 HSE Speaker Upgrade
I can think of plenty of things to do, it’s the cheap part that’s hard! [emoji12] I too am at that point where I’ve got to invest some $$ into the engine as it’s just time. Which, while necessary, drains all available “fun” funds. [emoji22] Seriously though, try adding a sub and see how it... -
2012 LR4 HSE Speaker Upgrade
That setup look pretty good! I also liked the pics of the installed version. I unfortunately have too many kids and too much junk that gets thrown in the back...so even though there are some sound quality issues with the tailgate sub box, in my case I think the whole system will survive longer... -
2012 LR4 HSE Speaker Upgrade
Truthfully, whether or not 300 watts is enough all depends. 300 watts RMS to a speaker designed to handle that amount of power will sound quite nice. As an example, I ran a JL Audio 900HD amp in my truck, and that pushed 500 watts RMS to my sub, which was 2 10” JL audio woofers, rated at... -
2012 LR4 HSE Speaker Upgrade
I don’t know what to tell you. Truthfully, I would do it all, but that’s just me....and I’d build it better! The book says the system is pushing 50 watts per channel, but it doesn’t specify whether it’s RMS or not. My guess is that it’s peak power which means you’re really closer to about... -
2012 LR4 HSE Speaker Upgrade
Eh, it’s probably something silly like LR “upgraded” 3 of the speakers to 2 way speakers or something like that. That probably wouldn’t be apparent in the manuals. I dunno.... Sent from my iPhone using Tapatalk Pro -
2012 LR4 HSE Speaker Upgrade
As far as I can tell, the Logic7 systems only ever had 14 speakers. I'm not sure where the 17 speaker configuration came from....a RR or RRS perhaps? I've attached a screenshot from the 2010 and 2013 LR4 service manual which shows the same speaker config's across the years. -
2012 LR4 HSE Speaker Upgrade
Thankfully, I don’t think my swap will be quite as intense as I’ve already got the Logic 7 system....but as I’ve found with these things, there’s almost ALWAYS a gotcha you have to overcome! Lol Sent from my iPhone using Tapatalk Pro -
2012 LR4 HSE Speaker Upgrade
Hey Guys, I'm a little late to the party, but I've been doing a lot of research on this subject. FYI, I too have a 2010 LR4. I never realized the amp was different in the 12-13' models, but it makes sense. In theory, the infotainment system shouldn't realize there's any real difference in... -
LR4 Electric Fan Swap
Those are exactly what I was thinking of using, then just grazing/soldering some pipe together to port it either forward, or up and out....again, I’m gonna have to see exactly how much room I have to work with when I get in there and start swapping! Sent from my iPhone using Tapatalk Pro -
LR4 Electric Fan Swap
Yeah, that was the general game plan.... But as I’ve learned time and time again, it usually take anywhere from 1-20 iterations before I get it right! [emoji28] Sent from my iPhone using Tapatalk Pro -
LR4 Electric Fan Swap
Hello Rover Universe! I’m not sure if everyone’s been following the thread on the search for a new crossover tube, but as I’m on the cusp of some system repairs/upgrades/modifications, I need your help as I’m struggling with one piece of the puzzle. Long story even longer, I’ve been... -
2010 LR4 Multimedia interface update/upgrade?
Not gonna lie, this has me interested, but there are A LOT of questions I need answered before I would even consider pulling the trigger on something like that. With that in mind, I sent the seller a rather lengthy info request...we’ll see what they respond with. Sent from my iPhone using...
