Turbo
71-BEETLE-SEDAN - November 9th, 2009 at 06:25 AM

How much extra would i get out of my bug if i turboed it. Not talking massive turbo but about the size of the ones from the ej20t.

Also roughly how much would it cost to do.



Cheers

Hi

That's a pretty open question, roughly you would need a decent motor built up, depending on size $2000-$10000, the you would need fuel management, inlet manifolding etc. another $1000-$5000, then a turbo $500-$2000 + intercooling and exhaust system.

Depending on how much you spend on each item is how much power you can get reliably, between 100 - 300 rwhp.

Makes a EJ20T sound tempting.

check out http://www.lowbugget.com 

He sells low teck turbo kits

Gives you a bench mark


71-BEETLE-SEDAN - November 9th, 2009 at 08:21 AM

Okay. Only reason im askin is because i saw one yesterday at supernats.

And makes am ej20t sound very very good.

Would it be no good on my 1.6?

to put on a stock 1600 it is too big.

1303 said exactly the right thing. It;s not just bolting it on. There is a gearbox that will hold it all together + engine management and brakes that you also need to think of. I have spent above the 10K mark on mine and not finished yet. Not a cheap option for HP.

Can I ask a dumb question (or two) to check my knowledge?

Firstly the kits from lowbugget don't seem to have any intercooler. Wouldn't you be nuts to go without intercooler? (and I know Bizarre wasn't recommending them, just providing additonal info)

Without intercooler you increase your intake temps which reduces efficiency because the mass of air getting in will be less, as well as putting more heat stress on the engine?

Isn't that just dumb?

IMO ... yes. Dont contemplate a turbo without an intercooler.

I put a golf turbo onto an otherwise stock 2 litre type 4. It made sense for me because I had all the parts on the shelf it only cost me a shitload of my own labour. I had the intercooler, turbo, pressure retard dizzy, DMTT weber, all the factory EFI hardwarre to use for intake, an exhaust system that someone had made up for a sigma turbo. That was probably worth a 50% gain over standard. Nice to drive with no lag from the small turbo on big engine.

In a beetle, even if you had all this stuff on the shelf you're going to have a lot harder task. The enigne bay is tight, you dont have a lot of room for all this stuff. You probably get better bang for buck out of a replacement bigger bore engine.

AJs kits are draw through meaning the carb is infront of the turbo.
you cant run an intercooler on a drawthrough setup only blow through were the carb is after the turbo.

intercoolers arent a necessity in lower boost setups.
alot of factory turbo cars dont run them
My SCoupe doesnt and neither did the navara

As T54 said its not a cheap option, theres lots of fabrication needed and they're an arsehole to dial in
money is better spent putting a good cam in, decent carbs like dells and abit of headwork


amazeer - November 10th, 2009 at 03:13 PM

but they all have watercooled heads.


71-BEETLE-SEDAN - November 10th, 2009 at 03:14 PM

Alrighty, well was just tossing up the idea, thanks for the info


Joel - November 10th, 2009 at 03:19 PM

Chris my 1600 bug turbo setup didnt have one either but it was a pretty rooted turbo and wasnt making heaps of boost

i was actuallly having more trouble with the oil getting hot than the heads


Joel - November 10th, 2009 at 03:22 PM

Josh, heres a bit of reading for you on a fairly budget setup

Good point about a tight fit. Like a watermelon in a sandwich bag!

I reckon $2k for a complete kit is pretty good. you could start with that and then add an water injection or an intercooler setup later. lots of of people had kits like this back in the 70-80s. they will shorten the life of your engine, but then so will webers and a bigger cam. turboes don't kill motors, drivers kill motors.

oh, btw, Wayne Penrose has a drawthrough turbo setup on his mango cab and he reckons it's a winner. He drives it all over the place.


Joels72Lowlight - November 11th, 2009 at 11:52 AM

Has anyone done this on a type IV?

I guess the only problem would be getting a header system.


Stanley - November 11th, 2009 at 12:21 PM

I ran my draw through set up on the road for 18months before I put it in the current car.
If you kept it at a reasonable speed (no more than 100kmh) temp was never an issue even in a Qld summer.

Cost me less than $2K and was good for a 14.6 on the qtr in a road reg '69.

Draw through is not as efficient as blow through but is way cheaper and easier and will still give you plenty more HP.

Really good thread

a few of them.

The first time I cut the flanges off a decrepit pair of heater boxes and used them as a starting point. When I rebuilt that one to put it in a type 3 I found some pipe that when squashed was the right size, with thinner walls so the exhaust ports could be opened up. The third one that I used all my leftovers on was a bit more elementary. It used the heater boxes in full, and a modified set of extractors.

me and my buddy build turbo motors all the time and dont have problems with them for less than $1800 just the turbo kit. it all depends on how your motor is set up and how hard you push the motor.


pete wood - November 12th, 2009 at 12:52 PM

^ precisely :)


Turbo54 - November 12th, 2009 at 03:40 PM

Who is going to build one and not push it to it's limits and beyond?
I understand you could do it cheaply like I am doing with my 265 hemi but as I know, it won't last and you will always want more. That is why my good motor has all the right bits and will do everything I ask it to hence the pricetag. Not trying to put a dampner on cheap setups as I know they are fun for a while but only for a while. Also you still break parts and need to stop. Just food for thought.

there isnt a lot of point in building a 150hp engine if you are only going to use 100 of them.

The engines are pretty bloody bulletproof if you dont use too many revs and keep the heads cool. drivetrain is bulletproof if you dont abuse the clutch. These are great cars for grannies :lol:
