lookin' good .... i love to see these tdi engines and trucks come together for another shot of life
very cool, i had a similar intercooler setup on my turbo 4runner years ago minus the scoop .... i am running a twinpass setup under my westy with a scoop and it makes for very cool iat's .... i'm interested to see how you'll like the lower gearing ... mine was 3:59 with 265 tires and it was way too tall ... i swapped in 4:10's and it's pretty good now ... what trans are you running ?
they are supposed to be 31.6, and like yours, because of the fresh tread they were slightly taller than the old 265's they replaced ... my fifth is .81 so with your .73 you should be fine with the 4:56's ... my truck would be a bit better with 4:30's but they are a somewhat hard to find factory ratio in the tacos ... the way my gearing works out is almost a match for a stock mkiv tdi fifth gear rpm wise ... so not bad at all because i have the extra torque to push 4wd brickJim how tall in inches are your 265s? I actually ordered 4:11s but after looking at the math again I need 4:30s minimum. They dont make 4:30s so the next step is 4:56. I plan on running a 31.6 inch tire so it will be fine. Its what is on the truck now but they are so bald they measure at like 30.9 inches right now. I have the stock NV3500 that came in the Dakota. I only use 4th now as its 1:1. It has a tall .73 5th gear. I dont think toyota put anything taller in 5th than a .83.
Yep big difference is 5th gear ratio. I have to go taller.Evguy put 31's on his cherokee swap, and did 4:10's. You could ask him what he thinks now that it's been on the road for a couple months, but last post on his thread he seemed pretty happy with it.

The stock 1.8t compressor lines hugged the compressor body. they must be cut and flipped in order to have enough room to swedge a line on.I'm new here but farm tractor dealers can order an assortment of fittings that will fit or compression fittings to adapt them

I thought about this and even ordered a VPK head compressor from across the pond to swipe the head since I couldn't buy just the head.. Unfortunately it only ca go on one way as there is offset in the bolt spacing that would put the connections at the 5 oclock position.you could change the compressor head to one that matches your truck's fittings or buy adapters .... https://coldhose.com/sanden-compressor-heads.html
I have the SD7 fittings in your link as they fit the VPK head.I've been working through making some AC hoses myself - and ordered a SD7 compressor head that had threaded #8 and #10 connections off to the side. This would have made it easy to then make my own hoses eliminating the odd-ball VW compressor fittings. However - once I had the VW compressor and my JDA style SD7 head next to each other I realized the VW compressor head is an odd duck. VW compressor has 7 bolts - all pictured SD7 compressor heads I have found have 6.
I have found that the fittings here: http://bouchillonperformance.com/inc/sdetail/6504 look an awful lot like the VW compressor pad fittings. They can be found elsewhere for less.
There are also these adapters from S&P: http://s-pautomotive.com/?product=mk4-sanden-sd7-compressor-adapters But I want to call and confirm that they are different than the Sanden SD7 fittings from Vintage Air because those DO NOT fit - I tried a set of those already.
Keep us updated on what you figure out - I'll update my post when I finally get it blowing cold - hopefully save some other folks some $$ that I have spent so far on R&D.
Im glad Mark and You worked hard to get the tune right. No doubt its a contributing factor.That a seriously impressive figure! FWD VW vans do well to crack 30, but they're literally brick shaped. Glad to hear she's working well.
Yea see for me at 100kmh/60MPH in 5th(.73) would only be 1650rpm with the current 3.55 gears. Thats to low for cruising and the EGTs go through the roof above 1300F. 4.56 gears are in my future. Its nice to know the auto does well without a gear change. What EGTs are you seeing on hwy 100kmh cruise?With the manual trans in yours I seen you where talking about changing your gearing I've drove mine with overdrive and without and the fuel millage never changed I have 355 gear ratio it runs 1900rpm at 100kms down the road
