Author Topic: using 1.6TD garrett turbo on a gasoline engine? (Read 3327 times)

do you think that garrett turbo off of the 1.6TD engine would work on a gasonline engine. specifically an aircooled VW engine.

would likely run 7-10psi boost pressure on an engine that will not see more than 6000rpm.

also need to know of there is a carbon seal available for this turbo (being a diesel turbo i am going to assume it doesn't have one).

I haven't pulled the engine to get at the turbo in my Quantum, so can't tell you from that VW part number. However, since the 1.6TD put out only about 68 hp (IIRC), it should work okay on a larger air-cooled VW engine. If you want to use it in a draw-thru setup, you'll need to ensure a carbon seal is in there. Garrett can supply them, I am confident.

how large is larger? i am running a 1776cc motor right now. it has 7.7:1CR, stock heads with 3 angle and upgraded valve springs, moderate cam (intake and exhaust lift and duration are equal), counterweighted crank and stock rods with ARP bolts (the stock rods on the air cooled motors are quite strong as are the cranks).

is the turbine flange unique or is it like a T2, or KKK flange? I know its not a T3 flange.

this doesn't sound too far off from the typical aircooled turbo. the most common turbo put on aircooled motors is the .42, .48 T3 (the T3 used on the saab 900s, some volvos, and some chryslers). that turbo on an aircooled needs 6500-6800 rpm on a 1776 or 1915cc motor and around 7k on a 1600.

From your description, it sounds like the turbo from a Quantum will work fine. The turbo on my Quantum's engine is a KKK K24, but I know Garretts came on them as well, depending on the model year. Same power turbo, though, so it too should work. Unfortunately, I am not personally familiar with this turbo, so can't tell you its flange style.

sorry but my english is not at top, what and were this : carbon seal?

A carbon seal is a seal that goes on the compressor side of the turbo (where the shaft and housing meet). on turbos run in a draw through configuration (carbureted engines that have the carb before the compressor inlet - basically pulling through the carburetor) the carbon seal prevents the tremendous vacum generated when off throttle from sucking all the oil out of the bearings and into the compressor.

ok! i understand!
why don't you try to make an intercooled fitting?
in this case you don't need this?

so may be you can answer to me, why in air cooled evryone make this ? ( carbu before turbo?)

i have a dune buggy lm1c ( french buggy like manx) and i will fit a 2l t4 engine with a turbo soon, i will use a tdi turbo but with injection, and watercooler.( :wink: )
