Turbo type 3
I have recently purchased a type 3 notchback.It has a 1600 stroked to a 1904cc engine with 74mm scat crank,90.5 mahle pistons (7.5:1 cr) ,berg 308
cam,CB performance 041 head ,1.4:1 roller rockers,twin 40mm delorto carbs,deep sump with remote oil cooler,and strengthened 4 speed type 3 gearbox
etc.
I was wondering what would be needed to turbocharge this car.I intend using a TO3/4 hybrid on 18psi.Would a turbo grind Engle 120 or 110 cam best or
is the cam currently in the car fine? (it has big lift & duration).Also should I use a single 48mm weber or go fuel injection such as microtech
with a 50mm throttlebody?
Also how could I upgrade brakes and diff etc?
Any help would be much appreciated. |

there is no comparison between injection and carbs. If you can afford injection that is teh only way to go. I'm no extert but I'm guessing
that a little bugs exhaust flow would be wasted on a inpellor of that size unless it was for hillcliming or something where it's always going to
be bounced off the limiter. What about a IHI RB5 or 6 or a T28? |

that car used to live near me, saw it on the odd morning, heaps cool.
that's a nice spec list. how does it go?
maybe you could just bolt on an OzNos kit if you want insane quarter mile times, and some block off gear for the street.
if you get injection, go all the way and get engine management with timing control. i wish i did.

first up, do you want just a little bit more power, or do you want it to absolutley hammer? it's all in the setup.
microtech is ok but they arent so good on a daily driver as they are more meant for wide open throttle such as in racing.
Driveability is really the domain of the uber-expensive ones such as MoTec and Autronic. The surprise here is the Delco is also very good on light
throttle and is cheap as dirt, i'll explain in a sec 
With ECU choice, the biggest issue is finding someone to tune it. no point buying a motec if there's no-one near you that can tune it.
For a turbo, look at something off a motor slightly larger in capacity, say 1800 to 2000cc's such as a CA18DET or SR20DET nissan motor. Some of
these are ball bearing, and are very cheap, and will absolutlely hammer on high boost, but will be pretty laggy. If you just want a little more poke,
look for a TD04 from a late WRX, as these can be had for around $300 or less, and are near new. People upgrade to the larger TD05 almost straight
away on the WRX as the TD04 was far too small for the 2.0L. (Too many hairdressers complained about lag on the early WRX that came with the TD05 ) so a TD04 should spin up quite well on the 1600.
Use the EFI manifold from the late Type 3, use a hall effect distributor from a Caravelle, and a small intercooler such as from an R32 skyline GTSt (I
bought two for $50 ea as they are too small for anything over 2.0, but will work well on the 1600).
As for ECU's and fuelling it, you'll need to run a fuel return line to the fuel tank, and fit a larger diameter fuel line to the injector
rails. Also, DO NOT use normal fuel hose as you will need to run the fuel at high pressure. VW's stupid idea of no lips on the fuel lines and
cloth bound fuel hose will cause spontaneous combustion of your car with an EFI fuel pump.
Look for a JE Camira fuel pump as these are the same as VL commodore, and unbelievably, same as VL commodre Turbo fuel pump! it's cheaper to buy
it from a camira, as not many ppl know that
MoTec is indesputebly the best aftermarket ECU money can buy, but they are priced to suit (over $2k just for the box) Autronic is a very close second
in both quality and price. (you get what you pay for)
Microtech is kinda bargain basement and will work, as will wolf 3D and Haltech but trying to find someone that can competently tune them can be a
nightmare. they are also not well suited to daily driving like the MoTec/Autronic.
However there is Delco. Camiras are finally making themselves useful by becoming organ donors :P
Find a rusty dead JE camira (MUST BE A JE! Only the JE, '88 and on model had the multi point fuel injection system you need) and strip out the
ECU, wiring loom, all engine and engine bay sensors, and aforementioned fuel pump.
Use some hose tail injectors that are the same impedence as the camira ones but from a larger cylinder capacity motor, such as V8 merc or 244 volvo.
you'll have to research which ones, I dont know specifically here.
You should be able to use the caravelle distributor with the delco ok, as the camira is hall effect too. the caravelle distributor should fit straight
into your block.
then find a tuner with Kalmaker that can tune the delco for you.
the best part of the delco is you can get a donor JE camira with almost everything you need for under $300 if you are lucky. it's also good for
nuts, bolts, screws, fuel line and various other things handy to have.
hope this helps. 
If it aint broke,
Make it go faster!!  |
