2005 Runner - Turbo or Supercharger??

[RunnerJeff]

I've been doing some research around the internet and I've come to the conclusion I want my V6 to go faster, sound better and perform better. Plus I want to dig into it more. I want either a turbo or a supercharger but I don't know which one would be easier to install and easier to maintain. If I got either, what else would I have to install for this set up to be complete? I know i'll need a cold air, gauge cluster, but I'm not for sure what else. All help would be great!!

I don't know diddly about whether Turbos or Superchargers are even available for a V6 (I know they made one for the 2004 V8s for about a minute there).

However, it's by my experience that 'used' engines typically take to a supercharger better than a turbo. You generally don't just slap a turbo and an intake on your car and go for it. It's a whole system (blowoff valves, intercoolers, oil re-routing). You'll also need to insulate the heck out of a turbo. They get VERY hot and I've seen several car-b-ques because people upgraded their turbos and didn't get it right.

A supercharger isn't as 'intense' on an engine so you can often get away with it. But for the ~$6000 or so it would take to do it right, you're better off just buying a little 2 door race car. That's what I would do. :hats off:

Here you go. A better explanation than I have time to write up. Its covers things like fuel system mods, changing compression ratios, ecu remapping. The whole 9 yards.

If you get it done, that would be sweet though!!

I'd go for the 1GR-FE supercharger kit for the FJ Cruiser (we have the same engines), but it's still $4,300+ fit kit and install....

Go for the sports car as a second car. Build yourself a factory 5 cobra like I did. Lemme tell you, that thing f*cking MOVED! On a total different level than a supercharged SUV.

You made me curious (thank you!) and I found this. Only good for the V6.

I'm new to the forum here, but I'll guess somebody on here has discussed this bad boy before.

I would say that you should PM SkylineGTR or whatever his name is, I'm sure he'll chime in on this thread once he see's it but he's big into making his v6 go fast, so you should follow his lead.

Just do some searching on here about turbo's superchargers and the like and you're bound to come across that name, I know it has skyline GTR in it.

Good luck.

I'm sure you couldnt go wrong with a TRD supercharger though, it's made for that motor so if you have the cash...

 

[rebelbowtie]

If you're going to spend thousands of dollars on forced induction, build yourself turbo set up. Bolt on superchargers like the TRD one is a waste of money IMO

 

[BlackWorksInc]

The guy who you really want to hear from is SkylineGT, he's built his rig pretty fast and IIRC he runs a supercharger on his V6.

As for the TRD Superchargers, they're pretty good superchargers. Toyota just doesn't run heavy boost out of them. My own personal mantra in regards to boosting is if I'm going to put the effort to boost an engine, I might as well go all the way and not half ass it. Whih in my mind is rebuilding the top, bottom, lowering compression ratio, and so on.

I also know that usually the more boost you run in an engine, the better the quality of fuel is needed and a lot more of it. (Could be wrong, just always noticed properly done set-ups to take higher grade fuel and such.)

 

[mrrab]

So, you could just buy a sports car.

I see value in having a supercharger or turbo if you're at altitude, otherwise it just doesn't make sense.

It does! Using more fuel when it already has an iffy mpg average to begin with. I'd do that. Haha

 

[TRDCal]

I'd go supercharger personally but I don't see the issue with a turbo. I mean hell look at Clownmeats rig, hes got a rear mount turbo! If I got a decent deal ($2000-$2500) on a nice used TRD supercharger, I did buy one. Sure its an SUV and not built for speed blah blah blah. I don't really have a good reason to argue why other than it would be really sweet and make for one badass 4runner!

I don't think he has one yet, I could be wrong but I think its on his "To Do" list.

 

[RunnerJeff]

Thanks guys for all the input. Ill see what the SkylineGT guy has to say. But I am really looking into this & of course looking for a used TRD Supercharger. In my opinion, I'll probably keep this rig around forever and I feel like I should turn it into a project vehicle. Hell I beat most people off of the line and down the stretch anyways. I don't see why I shouldn't up the anti and go big. If the supercharger does come with a complete install kit, I might go that route. Afterall this still is my daily driver until I get my bike, But the bike can't pull a trailer full of landscaping equipment so...., It needs to be a somewhat "quick" assembly.

Why not just trade it for a V8?

I was going to say the same thing but I did not want to turn this into another V6 vs. V8 discussion… :nono:

So… without hurting anyone feelings.. Since OP is looking for “go faster, sound better and perform better” solution then trading for V8 is probably the best way to do it; it is easiest and more likely the cheapest approach.
And one of the most important benefits of going with V8 (in my book anyway) is reliability factor: adding turbo or supercharger to any engine will reduce its reliability by default… so having NA engine that “go faster, sound better and perform better” and at least as reliable as his current one is very big plus.

My $.02.

:cheers:

Well that isn't a problem there. The vehicle next to mine is a 2004 V8, it's my dads. The problem is I want my body style, he just has the SR5 and I have the SE, his is the gray/blue color and mine is jet black. I have been contemplating switching motors but I feel that too complicated. He has all time 4 wheel drive and I have the 2wd/4wd option..

If you want power, Turbo. If you want easy install get a urd supercharger. For the time being I'm N/A, im not boosted but I have all the bolt on foundations for boost. Bigger fuel pump, fuel rails, id 1000's. When I graduate college I'm boosting and building my engine. Anyway regarding the TRD unit unless you have lots of free time or very creative you may want to save yourself the time for coming up with a way to bolt on the trd heat exchanger for little return unless you mod the hell outta the supercharger. If you got anymore questions post them up. For tuning I'd go for a pro efi or a aem. Go full standalone.

What he said if u have time and money go turbo. Either way turbo or Urd is gonna be 5k plus. TRD is ok the only reason im running it is bcuz i got i crazy deal on it and its gonna put me right around 400hp. Where i want to be. Other than that i wouldnt go that route. I would personally go Turbo. And for an idea of price. I priced a shop down here with legit big name parts for the kit Fabbed n all with full exhaust for 6500. Keep a look out on my link and its link. I should have everything in by the end of August latest.

 

[zimm]

I could be wrong, but I've never heard of anyone doing a v6 turbo in a 4runner. The manifolds and plumbing would have to be custom made, then you have heat issues, and how are you going to tune the ecu? Custom turbo kits take thousands of $$$ in Rnd, fab work, tuning. Plus they are for top end power, not low end torque, which is what you want in a truck. Forget that idea.

Factory supercharger is the way to go. If you think $4300 is expensive, give up on forced induction. Turbo would cost way more.

Or trade for a v8, but even that is only 265hp and not a rocketship.

Get another toy for speed like recommended here. I have a motorcycle. Also just sold a '12 Shelby gt500 that had 620hp. Was fun but useless for the driving around here in the dc area.

 

[rebelbowtie]

If you knew how to set up a turbo then you'd know it's not all for high end, high revving power. In fact unless you have a big ass turbo then you lose power as the RPM's rise.

But even with a big ass turbo their are ways around turbo lag and low RPM boost such as a quick spool valve or properly designed full length exhaust manifolds/headers that stay separated until the turbine housing.

My last turbo car made peak torque under 2500rpm and carried it over 5,000 RPM's

 

[SkylineGTRracer]

Correct, you'll need to look at the boost threshold of your turbine housing. There is a good list of standalone's so tuning is not an issue. Also remember these are auto transmission's that will have an affect on the "low end" zimm is talking about so "high end" in this case is what your looking for. Also when you want to go fast your in the mid to high rev range so again the "low end" thing falls short.

 

[zimm]

Yes you can have turbos with little lag- look at the BMW 335i. Max torque at 1500rpm. But good luck tuning a hand made turbo setup in a 4runner to be a street-able, drive-able, everyday vehicle. It can be done, but probably at a cost approaching what the whole vehicle is worth.
