Gen 1 Montero / 2.6L G54b Turbo Swap Tech
« on: May 23, 2018, 06:17:58 AM »
Starting this thread as a resource for G54B turbocharger installation onto a stock 2.6L Gen 1, focusing on directly swapping over turbo TBI G54B parts for a "low boost" build.  A high boost forged bottom end, port injection manifold, etc. would be the ticket, but this is a budget build list.

Please post any info, tips, or issues you ran into the way during a turbo install. Will update this first post as info comes in!

Gen 2 Montero / Re: Gen 2 Engine Swaps - Knowledge Dump

Is the 6G75 MIVEC available in any US sold car? I'll update the list

I've got the 3.8l 6g75 MIVEC in my 1990 Mighty Max. I don't think your options get any better than that. Everything bolt up just fine. One side of the block lacks a few motor mount bosses but there are ways around that.

Wiring harness isn't that bad either. I opted to use the existing one with my car and just ran a few extra lines for other circuits like knock, temp, o2, etc. I just made a conversion harness that clipped into my existing one. The real key is using the correct ecu. 98-99 montero and sport guys are in luck. You are perfectly poised to do virtually any 74 or 75 swap.

Gen 2 Montero / Gen 2 Engine Swaps - Knowledge Dump
« on: September 12, 2017, 05:13:50 AM »
In trying to determine all the various engine swap possibilites for a Gen 2, I didn't find a single thread that compiled all the info for all the various swaps possible (unless I missed it!) Making this thread for a knowledge dump of resources and experiences on engine swaps into Gen 2 vehicles. 

General Engine Info

Montero Engines

3.0L 6G72 SOHC 12V 1991-1995
151 HP
174 ft-lbs
-Least powerful engine offered in gen 2s
-6G72 block/heads/parts not interchangeable with 6G74

3.0L 6G72 SOHC 24V 1996-2000
177 HP
188 ft-lbs
-24V improves power over 12V 3.0L
-6G72 block/heads/parts not interchangeable with 6G74
-OBDII, more diagnostic sensors

3.5L 6G74 DOHC 95-96
213 HP
228 ft-lbs
-Top-end power, and power potential
-DOHC cool factor  8)
-Parts interchangeability with 3000GT/Stealth engines (turbos!!)
-Complexity, reliability, cost vs. SOHC
-Powerband for offroading (higher in RPM range than SOHC)
-OBDII with a multitude of diagnostic sensors

3.5L 6G74 SOHC 96+
200 HP
228 ft-lbs
-Most desirable for 3.0L vehicles
-Simple and reliable
-Many applications for engine parts compatibility
-6G75 crank fits in block for stroker engine (would need new pistons?)
-Less HP and top end than the DOHC 6g74 variant (and less cool factor!)

3.5L 6G74 2001-2003
200 HP
235 ft-lbs
-Slightly more torque than Gen 2 3.5L SOHC
-Wiring complexity

3.8L 6G75 2003-2006
215 HP
248 ft-lbs
-Most powerful engine offered in Monteros
-6G75 crank fits into 6G74 block
-ECU and TCU integration (? confirm) may necessitate swapping engine and transmission together, along with wiring harness for both systems. 
-Cluster from Gen 2 would need modification to work with CAN bus system, aftermarket tach/speedometer may be easier, or CAN bus display

Non-Montero Engines

3.5L 6G74 SOHC 96+ Montero Sport
200 HP
228 ft-lbs
-Easy to find!
-Some wiring harness differences possible?

JDM Engines:

6G74 DOHC MIVEC 3.5L (Pajero Evo)
276 HP
256 ft-lb
-Evo Power!
-Cost, complexity, parts are rare

4D56T Diesel (Intercooled variant) 1992-????
136 HP
236 ft-lb
-Diesel torque
-Available in Gen 2 JDM vehicles, swap would be easy with engine, harness,
-Accessory parts are unique to 4D56T (intake air box, etc.)
-Requires finding a complete donor vehicle to make swap feasible

Non-Mitsu Engines

Toyota 1UZ-FE Engine
251-300 HP
260-310 ft-lbs
-Potentially bolts onto gen2 transmission (confirm?)
-V8 noises
-Toyota reliability
-Timing belt

LS1 5.3+ 1996+ Anything Chevy
270-315+ HP
315-338+ ft-lbs
-V8 noises
-Requires full swap of engine, transmission, transfer case, custom driveshaft.
-OR custom transfer case adapter ($1000+) to adapt 4L60e to 31 spline transfer case

This is just starting point, please post to correct errors and add info and I'll update the main post.

Also had the chance to use some of this excellent "Shinetsu" grease on all the door seals.  I've heard it is used at the plant/factory for some vehicles.  It really restores the softness to the rubber seals, also works great on trim, works much better than Back to Black.



The dirt and old rubber that comes off with the grease:

Got the front end done on the both sides finally!  New rotors, pads, and re-greased the sliders on the calipers (both sides were frozen!).  Suspension replaced: struts w/ KYB Gas-a-Just, upper ball joint, lower ball joint, inner/outer tie rod ends, sway bar bushings and links, and the steering arms on both sides.  Need to do a string alignment to get it close, but it should drive much nicer now!

I'm up there in MI, so no worries about overheating, just getting the carb tuned to cold start properly!  I will be needing to address that among other little small things.

Gen 2 Montero / Re: SR Fender Flares on LS
« on: August 29, 2017, 05:57:46 PM »
OH!!!!! PA_JERO has brand new aftermarket SR clone flares for sale! 

 Short answer, the SR has a ton of rectangle holes in the doors and fenders to fasten the flares. Check out the ones PA_JERO has, they require nutzerts to install so it would be a lot less work and less holes in your body.

Is he selling them on a different forum? I can't seem to find the post here, or I'm being really dull

Eh you've convinced me, I'll look into the aftermarket ones!

I just want some sweet sweet fender flares and '92 SR wheels to match, just love that look.

Is it possible to swap the SR fender flares, bumpers, and ground effects onto an LS model?  Or are they integrated into the actual fender?

Looking into buying an LS but I just love the SR body lines! 

Gen 1 Montero / Re: Gen 1 Shifter Refresh - Seals & Springs
« on: August 29, 2017, 06:41:05 AM »
Now to find the return springs, was thinking of checking a trans rebuild shop who specializes in KM145s.

I would just give the Lowes stuff a shot, its so cheap and its meant for insulation on outdoor exposed pipes.  Make sure you clean the surface with acetone first so it sticks well.  Time will tell if it holds up to heat!

The interior is so quiet now all we hear is the engine roar  ;D Need to fix some exhaust leaks and get a fan shroud, it's noisy!

Dude, bummer the pics aren't showing, would love to see it.

Thanks for sharing info on the deadner you used. While I agree there is "lot of good info out there," in my opinion there is "TOO MUCH INFO OUT THERE." I read up and think I want something, then don't because that particular product smells like tar. So I start over and think I find something "then come to find out it doesn't do too well in the heat (i live in AZ) then i start over and find something, but then I find out it doesn't have adhesive back.......I think i'm just going to go to lowes and pick up the cheap stuff everyone talks about......something is better than nothing i suppose....amiright???

Weird, I can get em to work sometimes...I re-host on imgur later to fix it. 

Please let me know if the pics worked! Tried to fix it again.
