:) here is a rabbit I picked up a couple months ago. got an mk2 1.6 td, and swapped it in. Now im working on the exhaust so far i have a 3" dp, and Im waiting on a couple other bends to get here so I can finish the exhaust.
here is the car

Thats all I have so far.

got the exhaust all done up. These are quiet once the exhaust is pointed out back.

is a 3" exhaust not a little bit excessive??
I can barely fit 2.5" on my VNT20 flange, and this is an engine hoping to do 180hp
Any other plans for the golf(rabbit)?
-
maybe? it allows room to grow. i just picked up a gt2860 for it, so that 3" will help it breath a little better

Damn a GT2860?! If that thing doesn't spool til its time to shift, it won't be much fun...you may as well just use it in a compound setup, feed it with a K14 or something similar! 8)
-
I know, I hope its not to bad. I was spooling t3/t04e with the stock governor, and the gt28 has a much smaller turbine wheel, and much tighter housing, with a nearly identical compressor. So it should spool considerably faster, and I will try to shim the governor next weekend which will give a much wider power band. I hope it drives ok. if not ill try something new.
-
Link in my signature if there is any concern with opening the pump to do the Governor Mod.
-
thank you I have looked over that link several times. it will be very helpful
-
Feel free to PM me if you have any questions :)
-
ok probably will
-
How was the to4e? Do u no the specs of it? I would expect the disco potato to spool much much faster it doesn't have an ideal compressor map but I'm curious to hear how it works. Is it a chinese turbo?
-
yes its a chines turbo. I have used several chines turbos on this car, and been pleased with them.
specs for the t3/4 are
Compressor:
Trim: 55
A/R: .50
Inducer: 50.50
Exducer: 76.00
Turbine:
Trim: 73
A/R: .63
Inducer: 65.50
Exducer: 55.90
turbo kind of sucked but it would spool

the chinese turbos make me laugh, for one there is no such thing as a 55 trim t4, and then it lists inducer and exducer sizes, so you can calculate the trim yourself, and their numbers make it a 44 trim t4, again no such thing and it doesn't even match what they say, ha. anyways im still watching ur build here, very interesting, i don't think i'd ever run the chinese knock off stuff myself tho, id rather use used but good stuff. not that i blame you.
-
I'm not one to trust Chinese snails either, but from what I hear it's mostly concerns with the wheel assemblies and their general lack of proper balancing. MOSTLY. I've still heard of cracking CRH's, badly cast turbine housings, restrictive casting flash, inoperative waste gate actuators . . . umm sorry, not trying to scare you. :-[ I do hope you've scored a diamond in the rough, because a Disco Potato TD was a topic on my mind as well. Too bad the good ones cost 1,200 dollars. Ah, well, good luck with it being funner!
-
im with you guys on the chines stuff for long term. but for the short term experimenting, and abuse ive been doing they have worked wonderfully ;D.
on the inducer exducer measurements, thats what I have always looked at with borg warner and larger garretts. Im not even sure what a trim is ??? ? any who the "disco potato" spools every bit as fast as the stock t3 did. it climbs quickly to 8 psi were the wastegate is supused to be set. so tomorrow when it is cooled off ill put a few turns on the actuator and see what kind of boost this will make
-
On paper the compressor isn't good for a td but in practice who knows for anything bigger than stock turbos a modded pump is reall necessary
-
ya well see how the compressor works when boost is turned up. and yes I have increased the fueling on the pump ;) I have been playing with diesels for a few years now, but just recently started with the little vdubs.

Just ordered a new set of h beam rods! not sure when ill get around to building the motor but I'm excited
