ABF 16v Turbo...... Possible???

OK TT I know you know your stuff


8v 2E pistons would give low enough CR, but manifold would need to be home made or imported, which looks cheap but check the import tax or get a friendly vortexer to send it over as a gift


g60 management has potential, but not many people in uk will map it, jeff ex AMD quoted me approx 600 notes to map a turbo ABF, Jabba about 500 so depending on the deal you get, DTA or something may actually work out better/easier


cossie intercoolers look cheap on ebay and if you are only shooting for 200bhp ish should be ok. lots to it really


I agree it can be done cheap but you have to be well informed

 

there was a german site that had a full kit with videos of the demo car etc


mk3 ABF did 170mph or something bonkers, they offered a few states of tune, but also remapped ABF ecus. was about 3k for the kit


i'll see if i can find a link


however there is a rough 20vt in the scrappies for 350......

 

S2/RS2 pistons are 81mm. perfect for a kr but not a 83mm ABF

Thought I'd point it out incase you order a set

Audi 3A pistons are 82.5mm, and should drop the CR to about 8:1...

 

I`m half way through a supercharger conversion, I used 2 g60 head gaskets and ARP head stud kit to lower the compression, the fuel rail is a BBM one (work out around 150 shipped to the uk?).

Also opted for DIGI1, but if I did it again from scratch I`d of gone for the MegaSquirt (mapped from a laptop) the problem with digi1 is you have to have an eprom burned for every change to the map. SNS may be able to sort you a chip though? I was quoted 160.

Mines a KR but the ABF shouldn`t be too different.

 

Im putting a turbo on my 16v abf engine , if you can do most of the work yourself , it will be quite cheap, ive got atp manifold, stage 3 t3, g60 managment, cossie intercooler, tial external wastegate ,im doing the engine the way alot of americans do it by using the 16v head on a 2L8v mk3 bottom end. this gives you the right compression,and if tuned properley can be run up to 300bhp. if you use forged pistons and steel rods you can have a lot more pwer than that.

 

damo have a look at eurospeed.ca in performamce section has lots of parts you need ! prices don't look to bad tbh considing the exchange rate ! just need to find a friendly vortexer to send them over

 

Damo, as you said, teh 16v Turbo has alot of potential, and is one way around things people in this country seem to be ignoring. Look to the states and europe and they don't seem to really bother with the 20vt and stick to trusty old 16vt. I think tbh, if I were going that route I would prefer the 16vt route. And the good pound to dollar rate will make it cheap to get any uprated pistons etc from the states.

For the management front, you could run it on a Pug ECU, relatively cheap as chips and easyish to find and should help get good power gains. A bit of research into what ECU to use and who to get it chipped would be needed as I've forgotten the name of the one I was told is good

 

I was reading a feature in PVW the other day actually about a guy that was running pug management and Escort RST Turbo...... sounds like a proper mishmash of parts but they all worked very well and was very cheap to do.......

Deffo lots of options out there to build this sort of engine..... and as you say, why there arent more people in this country doing it i dont know..... seems much easier that paying for and fitting a 20vT....

 

I disagree with the easy bit, if you've not got the knowledge/time/space/tools etc to do the conversion yourself then it's always going to be easier to pay someone else to slap in a 20vt for you. I think that's the difference, over in the states there is a lot more space - having a big double garage to rip cars apart in is almost the norm over there. Their DIY culture isn't dying as fast as ours, the british attitude to virtually anything these days seems to be 'get a man in to do it'

 

yeah see i have access to that so i forget that alot of people havent and cant do these things themsleves..... i will say that i see not havent the knowledge to do something is not a reason to get someone else to do it.... the knowledge and information is out there. You just got to find it!!

As you say though, its down to attitude in this country, most seem to be lazy these days which is not what car modifying is about i dont think

 

if you can get the parts from a friendly vortexer, then it'd be great as the 2.0 capacity will get it on boost sooner than a 1.8 i guess [total guess ]

ABFs didn't come with sodium cooled ex valves, but KRs did so some jiggery pokery may help

8v pistons will be the cheapest, but if importing from the states then going to 83mm won't cost much more.

Also the yanks will buy your ABF pistons from you for good money

i can't see it being easier than a 20vt really, as you still have to plumb in the intercooler etc, and wire in an ecu to run it.

some good prices on gt27rs turbos at the moment, but make sure you have a beefy gearbox and a nice diff or it'll be wasted

 

Nah, keep the standard 020, then you can have a race with tubs to see who's box goes first

 

Go to the atp turbo site or eip they are both in the states and do a lot of turbo parts for volkswagens .they also do alot of the silly little parts that you cant get in this country.In this country they say "forget it just fit a 20vt" but over their and also in europe they are alot more willing to help with home made projects

 

"Killa" from vwsport.com got 506 whp (I think that's right - over 500 anyway) from a turboed 16v on std. bottom end - including reused rod bolts. Not exactly going to be a daily driver with a turbo that size, but I don't think a beefier crank or rods are going to be neede if you run an earlier 2l 8v block with forged crank and rods as standard.....

 

The ABA is the 2.0 8v xflow, the bottom end of which is fitted to the 16v
head to get a lower compression ratio. That's why the "ABA 16vT" is so
popular on Vortex. The VW Sport forum is pretty good too.

 

As far as I know the 2E bottom end is pretty much identical to the ABA
bottom end.

 

guys I think the US guys only use the early ABA as it alledgedly has a forged crankshaft. later ones aren't forged I believe.

 

well if going for low comp pistons for a turbo ABF then why not spec em for a deisel crank too, you wont break that easily

 

yes ,the aba block that they use im the usa is the same as our 2e mk3 gti engine. try not to use the later gti 8v block which i think is agg code ,because its not as strong an doesent have under piston oil squirters,I am using this later agg engine but only because i found one, very low milage,im hoping it will last for a while . 2l8v gti engines are easy to get hold of anyway.and dont be put of by any one who says that the pistons will hit the valves with this combination.ive done it and they dont.
