turbo in a daily driver
57 Cal look - March 17th, 2003 at 08:35 PM

Hi Guys & Girls,

Ok .... i want to build a turbo motor for my daily driver... i have no idea so i am hoping to hear from you people who know.

I am thinking of just building a 1600 turbo... i dont want to drive like a yahoo.. just a nice responcive motor to get about with... i might go up to a 1776 turbo.. but we will see.

what i need to know is ....
* what would be the best sort of turbo for this style engine
*are there any special items i need for the internals of the motor so i won't kill the engine in a hurry... now remember i dont want a race car... just a nice daily driver
* could i use a prosche fan conversion on this motor as well... will i be able to run a manifold to suit both the turbo & the porsche fan shroud kit ? .. or is that going to be a custom buld job ?

thats about all the questions i have for now... if any of you turbo guys out there feel i have missed anything that is blindingly obvious... Please let me know ;)
cheers

Hi there,
If you would like to know the low down on a turbo, give Michael Shimmotech (Shimo) a call down at Dunham Automotive at Woollongong.

He can set you straight on all the goss...he and a few of his mates were/are big into turboing Beetles and Kombi's!

Good luck with the project, and keep us all informed of how it is going!

Regards
Kombiluva

go blow thru and use a turbo from a car with similar characteristics to what you envisage you your engine to be like. Oh and there are some awsome books on this subject, turbomania is excellent info for VW's, maximum boost is another good read and I have an old one by hmm Corky Bell I think. Just put together a tuff NA engine without much head work and a stock cam and then turbo that. Should work out nicely :bounce I'm putting together a 2276 turbo for my wifes dub :)

[size=6]MAN THATS ONE COOL LOOKING MOTOR[/size] you have done a fantastic job! it's gotta be one of the neatest jobs I have ever seen! It's made my day just looking at it!

cool looking. pity it doesnt go. how the hell is that coil supposed to live? How does the entire motor live sucking air straight off the exhaust?


555bug - March 18th, 2003 at 04:09 PM

not my motor :( I wish !! just a picture for insperation :) but yes a turbo bug for the wife should be fun.

Chris
what is the matter with a coil living at the back of the car/motor?
Where is the motor suckin' off the xhaust?
Isnt there a dual feed for an injection system with the breather in front of the genny or something?
To many shiny bits and not enough grease to tell where things are meant to be.
Gimme a motor with grease any day!


Che Castro - March 18th, 2003 at 05:29 PM

yeah i am seriously considering doing a small displacement turbo in the future when i can afford it. Probably 1776 or 1914.

i think it is definitely worth your while to go to a larger bore like 94mm, and get forged pistons and good rods combined with a good CW crank. A dual port case with 8mm studs and larger oil galleries is probably preferrable.

Definitely go blow thru programmable EFI, my guess is you might not need 911 cooling... although it looks good. A properly sealed doghouse (preferably a Fuel Injection shroud) system with all tin can cool a 2.3L NA motor.

definitely run an intercooler, either air to air (can be a bit cramped) or air to water, you need a Blow off valve (plumb it back to the intake). About manifolds, there aren't really many turbo kits available in australia so pretty much all of the exhaust manifold, intake and all other turbo tubing will need to be custom.

You don't need much work on the heads as said before, a stock cam will be ok but it's better to run a turbo cam.

hey so 555 bug, i'm guessing u have an EJ20T or similar in ur bug? is ur wife a good driver? that motor will haul some big time ass 200+ HP???

here's the V-Force 2.3L Turbo Bug... guesstimated at 200+ rwhp and a low 11 sec 1/4

I have just decided to go efi on my turbo project so may be persuaded to part with my dmtt weber for a sensible offer if your intersersted in blow thru carb.


kombi_kid - March 18th, 2003 at 07:43 PM

hey
what size carb is it for what size turbo???
cheers
rhys
p.s. what money are we talking


Menangler - March 18th, 2003 at 08:40 PM

Why not just buy that turbo engine that ????? (who had that again) the one that Shimo built. You wouldn't build one for that price.

The coil is maybe an inch away from an exhaust pipe. Its going to be toasted. There is no rear tin. The fan will draw hot exhaust air.


shiftyvw - March 19th, 2003 at 06:19 PM

Its a 32/34 DMTT progressive weber, made for blow through, really Im not sure what they are worth as ive heard 200 to 1000 dollars and I paid something in between so feel free to make an offer if your intersested, has fuel reg etc with it.

turbo = $

building, maintaining and tuning.

i would prefer NA for a daily driver.

but dont let me discourage you.
i think it was matara (Steve Moran) who had a turbo engine for sale a while back dave.
if i was going to turbo a bug, i would buy one complete.
save $.

(btw if i had enough cash i would love the acceleration and whooska of a blow off valve in a bug!!)
WHO WOULDNT?:)

I dont know about the $$. Costs money to build NA too. Still got 4 plugs, 1 set of points, 8 valves, same amount of oil in the sump. Same maintenance.

I'm in love with my turbo system. Putt-putts around town like a stock 1800 yet pulls the toughest hills in top gear no problems. No problems overtaking on highways. Very quiet. No need for revs.

Buy the ShimoBuilt. Its a good setup. You wont be sorry.

KombiKid buy this carb! If you ARE going to go turbo and you dont have $2000 for injection system plus dynotuning its the way to go. If you change your mind later you will be able to sell. I'd buy it myself if I wasnt a cashless uni student.


kombi_kid - March 20th, 2003 at 04:48 PM

would it work well on a 2L type 4 engine or a 1916 type 1???? (either me or my bro are gonna do it)
cheers

I think a turbo is more driveable and has less maintainence when you get to larger engine sizes in a type 1 or type 4 compared to NA of a similar power. A turbo is also more driveable and flexible in a high state of tune.

A type 4 would be great to turbo as it's got a strong bottom end, although you probably want lighter rods so you could go to type 1 rods (and get type 1 forged, pistons REAL forged not Cima's) and get a stroker crank, but thats expensive...

Of you could just turbo the stock type 4 2.0L, the stock 2.0L rods are strong, just replace the bolts. It would probably be in a similar price range as a turbo 1914 if you are staying with pancake cooling, and it would last longer and have a fatter powerband.

A turbo 1914 would be great too, cheaper for an upright conversion


OvalGlen - March 20th, 2003 at 09:06 PM

Ok you could also talk to Brenden at CBBVW check the Bussinesses Guide on this forum. He has turbo Beetle for some time.
One mechanic there turboed a standard 1600 and thrashed it to see how how much boost and how quick he could blow it up.
It lasted a long time of abuse up to 15lbs
boost he told me.
So with gentle boost the standard motor would appear to be able to last.
The intercooler idea is Very Good. Less heat stress on motor.

Thanks guys... i knew i could count on the greater minds to offer up some things for me to think about.....
please, any more thoughts... keep them comming.... i am starting to read up more on this .... and your points so far have been VERY helpful... also i can say that Shimo.. can expect a call some time soon , so i can pick his brains a bit...
i dont think i would go bigger than a 1776 turbo motor.. as i do really want to keep it small.. and dont want to end up with a big loud motor ... that is a dead give away... now before i get jumped on for that last commenet... i only mean .. that sure a big 2lt plus turbo motor would be great..... but i am not building myself a missel for the street ... just want nice Quiet performance, and something that looks pritty trick.. when i pop up the engin bay lid.

again thanks ... and please keep your thoughts comming
cheers 57 Cal look :bounce:bounce:bounce

yes. you will probably need to change jetting. thats all


Che Castro - March 21st, 2003 at 01:32 PM

go for a 1914, its a big jump in power. A 1776 won't be any quieter than a larger motor, turbos tend to diffuse the sound a bit anyway so it won't be all that loud

kombi_kid - March 21st, 2003 at 04:27 PM

hey
thanks chrius i will go talk to the guy thats doin me turbo and see what he thinks!!!
cheers

70AutoStik - March 21st, 2003 at 10:18 PM

Personally, I'd skip the 92 and 94mm options - turbos are renouned for producing heat (the great enemy of the air-cooled motor) and these two can push the limits of a NA motor. Forged pistons are definitely recommended (the Mahle forged pistons don't cost that much more than the cast,) and an aftemarket crank (one of the non-forged chrome/moly units, such as the scat, should do the job - unless you plan on getting silly.) Keep your compression low and, as you'll be spending several grand for the turbo anyway, consider water injection.

baybuscamperkid - March 22nd, 2003 at 11:01 AM

does anyone know anything about turbo-ing a subaru 1.6, where i should look, what it would cost etc.?


Che Castro - March 23rd, 2003 at 11:48 AM

what kind of engine is that ? and EA71? It would be difficult and expensive to do a custom setup, it would be cheaper and easier to just get a front cut of a factory turbo engine like an EJ20T or an EA82T


1303Steve - March 23rd, 2003 at 04:55 PM

Hi

I saw a 1600 subaru impressa motor in a bug, it fitted really well, it was 16 valve etc, not sure how much power but it would have to have more that a 1600 twin port.
