What's your budget?

Have you upgraded the transmission and brakes yet?

Up grade trans or brakes has NOTHING to do with his question.

That was a wrong answer..

DRAG car yes but for the street NO upgrade is needed.

I have a 66 bug 1776 Turbo and the trans and brakes are all stock. Engine is over 20 yrs old and in it's 2nd 66 bug and both had a stock trans and brakes.

I change cars but keep the same engine.

A 1915 Turbo would be no problem in any stock running gear. As for cost it can be done with Used Turbo modified or a NEW Turbo kit for that size engine. There are a few on Sambo that have done a low cost Turbo installation.....all comes down to a choice which way to go depending on $$$ flow. I went with the NEW high end doing mine thus the long years of service.

I went with a stainless exhaust....never a problem.

A good street compression would be 8:5 -1 using 87 gas.

041 heads etc with 40x35 or 39x35 will work.

Carb is a Weber 40DCOE and jetting is easy.

Engle 110 Cam with a 69CW crank combo will work.

Key thing is to Balance the bottom end.

Basically a 1776 has the 90.5 cyl while the 1915 would be the 94 using more gas.

Decades ago I tried different combos for a Turbo in my NHRA Legal Dragster and found that a 1776 would work real nice in a stock bug, thus the setup went in a 70 bug I then had and later to a 66 bug ending to today.

As to compression I started real low and needed stock in Shell or Mobil as the engine gulped gas. Increased the comp for the same HP and less fuel was needed. Some run a higher comp so a matter of choice and needs.

Just a thought and personal experience.

Not sure if you are looking for a driver or a drag car.

For a driver I would contact Joel Mohr:
http://www.mohrprf.com/
http://www.thesamba.com/vw/forum/viewtopic.php?t=271444&start=460

For a drag car I would contact VW Paradise:
http://www.paradisemotorsport.com/

Of course I would probably talk with Pat Downs at CB Performance, and Kawell in TN before making a decision

Don't do a lowbugget kit if you do. Expensive moneypits.

I've helped put together a couple of the CB kits and they are nice. the turbo hideway headers are very good products.

Don't lock out your timing, use a real boost controller or go crank trigger, which leads you down the path of EFI, which is the best way to do it right. Megasquirt + Mexican EFI hardware + CB turbo hideaway header = clean, efficient, powerful, endlessly tunable on a better budget than you think.

first turbo setup I worked on was a K03S blowing into a stock 34PICT-3, with homebuilt manifold, and a boost-referenced stock fuel pump. Small turbo= instaboost. ran great but kept going pig rich on the top end. talked him into megasquirt EFI and he ordered up a set of intakes etc. from Antonio triejo. night and day difference in smoothness and driveability, and it was great on gas too, like 32MPG hwy. after that i decided that turbo+carb was a waste of my time.

What sort of car? only way I would go turbo on my own car is if it was a Baja, let that beautiful mess hang out to show it off to everybody Twisted Evil

Do lots of research..........start here.

http://www.shoptalkforums.com/viewforum.php?f=3&sid=336096b380c0c1446ab8dc443fc9d7a6

Look at as many systems as you can and if possible see how they run.

I see you are in Washington.
There is a big VW show coming up in the middle of July in Seattle. Go there and look at a few turbo systems if you can find any.

I plan on being at the Burger Meet on Friday night and will have my turbo buggy there if you want to see it.
You might be able to catch Mario there and he can give you info on Fuel Injection which I recommend for a great driving experience.

I feel a blow through turbo system will give better results in the cool, wet climate of our State.

Just remember......you are the mechanic and the engineer when you go turbo. Even if you buy a kit you will spend much time installing and tuning it.
Most kits are a bunch of parts and you will need to make them run.

When you look at turbo cars, ask how many miles they have been driven. That will tell you how well they perform.

Glenn's advice is valid, I don't care what the other guy said. If you plan to use the turbo's power a transaxle upgrade will be needed. A well built 1915 turbo would be pushing somewhere between 150-180hp

Upgraded brakes is just common sense...and a good idea if your engine is stock or high performance.

There are a few kits available as mentioned above

Wink

Seen a friend put a 2276 in with a stock tranny. When he got to the first top sign he dropped the hammer and the tranny let go.

Years ago I was chasing a Corvette in the parkway when we came around a turn and the cars were dead stopped. He hit the brakes and came to a stop. I hit the brakes and barely slowed down so I headed for the grass shoulder and finally stopped after passing a few stopped cars. I have since upgraded my stock drums to front disc and Type 3 rear drums.

Every new car manufacturer that offers a hi-po version of their 'standard" car included brake and suspension upgrades when they add a high HP engine.


Mustang GT
WRX
Porsche GT2
Challenger w/ Hemi
Lexus F Sport

All are not just engine upgrades.

Correct, but a stock engine will not get you to 90-100mph.

Also when you have a high performance engine you tend to accelerate faster.

one has to plan ahead a little when stopping with
drum brakes .... and if one needs to perform a panic/
quick stop with drum brakes..... you are in a panic
until you finally stop Shocked

A Turbos function is to operate under Boost which is generally done on hard acceleration thru the gears.

Driving normally the vac/boost guage will move between 16 and 5 inches of Vac as it does on my Turbo when shifting gears.

If I step harder and longer on the gas pedal I go into BOOST mode.

Works great on the FWY on ramp etc while in city traffic with the traffic signals a little difficult w/o drawing attention to myself.

I have a longer exhaust pipe coming out of the Turbo thus a slight megaphone sound. Do have two extra pipes so I could cut one down to a small short outlet. Will take a looksee tomorrow.....no harm no foul.

Trans up-grade: at least a super diff
or don't do burnouts : ( I made 6 passes on a bone stock trans and didn't hurt a thing inside the trans) 73 with 10/15 spiders ,,

turbo bugs love STOCK ratios
Just like HRVW sez: they drive like a stock bug (in vacuum 15-20" on mine step on it,, an hang on 12 lbs on pump gas 1915cc all Balanced
40 DCOE or 45 dcoe keep the vents about 30mm
turbo header 1 1/2 or 1 5/8 (check with CarCraft in Riverside
cam? keep it small(dur.@ 250 or less don't need a turbo cam
full MSD ignition
T3 or t3/t4
full flow oiling & 1 1/2 qt sump,, this will push a bug to an 11's in the 1/4

This is only true if you are just cruising at 60, even then I got tired of slamming on the brakes and still having to dive into a shoulder while going around a blind turn. After the third or fourth time that happened I threw the drums in the garbage.

Accelerating to 60mph with a stock engine that is starting to run out of breath is no comparison to a turbo car pulling hard past 60 with power to spare. With the design of a VW being light in the front, RWD and rear engine I found the need to go 4 wheel disc and a valve to adjust rear bias. You don't have the weight in the car to slow you down like a big muscle car or truck. Your brakes and a fast downshift are important to prevent an accident. If you don't think so, I don't think you've driven a bug that's fast enough to make you believe in it

I took my 1915T down the 1/4 one day, nearly ran off the long end of the track because drums suck. I literally hit the pedal and nothing happened. Turbos and disc brakes go hand in hand IMO, I wouldn't drive a turbo again without better brakes take it from me.
