ARPs to stop the head lifting with boost.

Cool project, and I applaud the idea of doing the brain work before the building. It takes a lot of time, but in the end it's worthwhile. And you learn a lot too.

When I was doing the specs for my build, a tuned k04 b5s4 was my target to beat. Spent quite a bit of time online reading, watching videos and using the BorgWarner MatchBot. From what I could gather, 60#/min is about the target I was looking for, so that equals ~GT30r size turbo. After much research and comparison, I chose an EFR7163. Hope that helps.

What car is the motor going into?

I'm just starting to look at the BorgWarner matchbot, got no idea what most of the variables mean but I'm eager to learn as it seems like it will educate me on some of the more intricate details of turbo operation! Thank god they have tutorials too

I've been flip-flopping on whether I'll be able to do this, but I think it's worth having a car I really want to keep for many years to come once I get to NZ at the expense of a bit more of my house deposit. I've had a few emails with the guy behind the VR5 turbo kit at carlicious parts in Germany, interestingly he told me this morning he ran standard drivetrain with 400hp for 3 years no problem and, for what I'm looking at making, the GT3071R running 1 bar will make 280hp.

I don't know how it compares to other turbo kits (except for a lot of stuff on ebay for VR6s and E36 BMWs which all look cheap and seem suspiciously under £1,000 for a kit of parts that are supposed to boost air and fuel into your car's engine...) but €4,400 seems reasonable for a kit which clearly has a few years behind it, not strictly R&D but still customers and indeed the chap selling it running with his own car.

Other than what carlicious parts sell I'd need a stronger clutch, get the 'basic' map customised somewhere in UK, exhaust - ideally with one of my cutout valves as part of it - and do we think a FMIC kit designed for my 1.8T (as it's supposed to fit in the B5 engine bay) will be suitable? The kit from carlicious parts is specifically for the transverse engines so intercooler and downpipe aren't 100% ideal for this. But as he told me in an email "the intercooler piping needs to be changed also. i can attach universal intercooler hoses and pipings if you want."

hi, just curious to find out if your any further forwards with this?

what car are you intending on installing it into?

Jase.

No I was sure I could afford the parts and all other items/services required to get it working in my B5 quattro but the cost of importing it to NZ when I move out there would likely be too much for me to take out of my house deposit fund. Before I gave myself the chance to properly investigate said cost I got it into my head that a good use of my free time between selling my house and leaving for NZ would be to go on a road trip through Europe in my A4. I'm going to head to the Alps to see Rallye Monte Carlo then tour round France/Switzerland/Austria/Germany to make my way up to Sweden and spectate at Rally Sweden. I plan on going to the Audi and Porsche museums too.

I really wanted to do it because it would be such a unique car and would be something I'd keep for so long but really I don't know how little I'm be earning in NZ so I should remain slightly sensible (not including the expense of a four-week drive through Europe!) and just buy a Legacy GT-B once I'm out there and hopefully still have a healthy amount of cash for a deposit for when I buy a house again!

I just can't keep this idea out of my head for more than 3 days at the most, so it's not dead in the water just yet... As I see it my options for the foreseeable future in terms of my personal motoring are:

A) Buy a 3rd gen Legacy twin turbo (so one of either a GT, GT-B or GT-B E-Tune) for somewhere between $4,000-$8,000
B) Buy a B5 S4 once in NZ and buy the parts from carliciousparts and find either VR5 engine complete (local or from Europe) or a cheap Passat VR5 donor car and get a manual ECU from Europe (they love their automatics in NZ for some reason). An S4 can be had for anywhere from $8,000 and up - which doesn't seem too far off UK £ prices.
C) Actually use my time off (now that I'm coming to the end of my last week at work) to properly find out if I can import the A4 by sending out enquiries on car importing to NZ. I had a quick check the other day and read that you can't bring in a car which doesn't meet Euro4 emissions unless you aren't going to register it on the road.... As I had a few removals companies come round for quotes and they mentioned cars I'll find out for sure.

In all honesty option A) is likely going to result in B) sooner or later. A similar option to B) is buy a Mk1 S3 and do the swap - but only if I'm satisfied that one of these Haldex controllers can actually make it handle like a 4WD vehicle - I doubt it, Torsen is just better than everything else.
