problems!
by vlksdragon
ok, so after my install of a BAE turbo kit onto my 1.8 JH motor, I've run into some problems. The turbo ran fine for about two weeks, and now it won't hold an idle and it's lost a bit of power at the top end. So I stuck my head under there, and found that a bit of the gasket between the turbo housing was hanging down, and one of the bolts for the housing had backed out. Would this cause the symptoms I've been experiencing?
Is a turbo difficult to rebuild, or should I just spend the $300 to have turbonetics rebuild it?

Power loss
by Dolemite
You didn't mention where the bolt backed out,If it was between the turbine housing and center section,Chances ar not much exhaust would leak there and therefore not much power loss,But a manifold to turbo bolt backing out would certainly cause a big loss of power.

idle
by jerry
if it won't idle then you have a leak between the turbo and the butterfly or between the flap and the turbo. don't blame the turbo yet. get a copper/metal gasket for between the turbo and manifold.

idle
by vlksdragon
I wasn't blaming the turbo yet, but will a leak at the housing cause such a problem? I checked all the connections between the turbo and the throttle, and everything seems tight. Would a faulty aux air regulator cause idle loss?

thanks......

idle
by Kurt West
Could it be you suffed your motor? A little to much foot? Low compression in one or more of cylinder would cause a bad idle and loss of top end power. I would get a compression check or one better a leak down test done. It can't hurt.

shouldn't have....
by vlksdragon
The motor was in top shape before I installed the turbo, and the BAE system is only 6psi, so I doubt I stuffed the motor that quickly. But you never know......

Burnt valve?

I'd do the compression test.It's cheap.

everyone who's using the SDS system
by fred
Just have a few questions for those of you that are using the SDS engine management system.
I'm not planning to go turbo, atleast not this year, but I want to get rid of Motronic on my 1992 Jetta GLI 16V 2035(many mods),due to problems w/ idle. Anyway I went to the SDS website and it looks like a good deal to me. My question is about getting air into the engine. If I'm not going turbo, I assume I still use the stock intake manifold(or individual TB's, which I cant afford now), right? Since the SDS system controls the injectors I wouldn't need my airbox, so where would the filter and airflow-meter go?
Would I use my injectors or get something else? What size? What "options" would I need for my application(I already have a Split Second air/fuel meter)? Thanks for any info.
Fred

Fuel injection
by Barry
Fred,
If you use a SDS on your 16v you will be able to do away with the complete motronic injection system. This means you can get rid of the air box, injectors, distribution block with stainless lines, ect... Things you will need to do are; 1) get new fuel injectors and make a custom fuel rail. 2) Fabricate a tube that connects to your throttlebody and directly to a K&N filter. You will not use the airflow meter-- the SDS works with a map sensor. Therefore you will have no restrictions in the intake tract. 3) install a crank trigger for the ignition. ( I think SDS sells one that you can adapt to your crank pulley ) I believe the two Rabbits on this page use it. Contact Justin or Paul W. for more info 4) You can use your intake manifold but you have to adapt a TPS ,( throttle position sensor), sensor to the VW throttlebody. 5) You will need a aftermarket fuel regulator to lower the fuel pressure of the stock cis motronic system.
Good luck,
Barry

Barry,
Thanks for your info. If Justin or Paul W is out there please contact me(spankacivic@hotmail.com) so I can find out exactly what you did. ie how you made the fuel rail,TPS, etc. Or call me at work 360-475-4708(I'm there M-F 7:30 to 3:30 pacific. Thanks.

Go to your local pick-a-part wrecking yard and get a fuel rail, pressure regulator, and injectors from a bosch efi car(sabb turbo, bmw 318i, etc) Get a throttle body from a toyota MR2(older one) or corolla GT-S. Order the SDS EM-3E (don't worry about the distributorless set-up the E is all you need) Also get the injector bosses to make life easier. Head to a machine shop with your parts and your intake manifold. Have them make an adaptor for the throttlebody, add the injector bosses and fuel rail mounts. As good as the SDS is and simple to use, it still take a great deal of work to install and make work properly. Another thing you need to use the coolent chamber in the toyota throttlebody for it to work, but its a nice warmup feature.

The SDS system is the bomb. I have it on my turbocharged Golf. It is the coolest thing you can do to your car. The system works super.

shaved head
by jerry
my head is a 84 gti shaved .130. what compression would that give me with 8.5:1 pistons?

shaved head
by seth
Jerry-

Never heard of anyone shaving a head 0.130", except triumph tr6 engines. IIRC, the book says 0.020", and i have never heard of anyone going past .040"

Assuming you have the stock 84 8V motor shaved that much:

Swept displacement per cylinder =1780.9/4=445.225cc....

total cylinder volume= swept+clearance volume....

total cylinder volume/ clearance volume =8.5:1....

swept volume= (8.5-1):1 x clearance volume....

445.225cc =7.5 x clearance....

clearance=59.36cc....

reduction in volume from shaving 3.3mm (after subtraction of squish areas)(assume 70% open area) ~12cc....

(445.225+59.36-12)/(59.36-12) = 10.4:1....

This comes close to the 1/2 point compression ratio per millimeter theory for the 8v heads.

RE Extrude Hone
by Chris
Anybody out there ever had anything Powerflowed by
Extrude Hone. I called the guy andhe said a g to flow both intake man and head porting to gasket match. A grand is a helluva head job.. Its a G60 head mated to an ABA 2.0 running JE 8.0 to 1 w/ a
T3 super 60 at 12 lbs daily driver.Any reports on
previous results w/ Ex Hone would b apprec.

static compression #'s
by jerry
what psi does your turbo engine(16v or8v) give when you do a compression check?

mine is 210 psi. is that too much? hehehehe. if 9:1 is 174 psi and 10.5:1 is 189 psi, then 210 psi has to be around 12.5:1 ...i love my alcohol.

it's not a linear relationship
by seth
it's neither adibatic or isothermal

Basically, the heat of compression changes the pressure generated. There are other issues like cam timing too, leakdown and cranking speed. So it's not a linear relationship. I hear that 10.1:1 GTIs new can hit 210psi. And new they are really at 9.6:1. The 10.1:1 is after carbon build up in the squish areas.

IHI turbo anyone ever used one
by nivekthornton
has anyone out their ever used a IHI turbo from a 87 t-bird? also what type or size of garret turbo comes on the chrysler daytona or lazer? I found two in a you pick yard today 1 was a garret the other was a Mitsubishi which one is best? and what size are both?

Daytona Turbos
by Rob
The IHI turbo, to my knowladge is built to handle about a 5.0 litre engine. It would spool up on a smaller engine, but i guessing not until about 4500 rpm which would not be real fun comming out of an artful corner.

The turbos on the Chrylser Lazer and Daytonas, I believe, are a T-3 derivative, but the flange on the exhaust housing is tanged, or trapazoidal. If you manage to get a manifold fabricated, it probably would work, but none of the standard T-3 or T-3/4 hybrids would fit.

On the up side, the stock manifolds from the turbo diesel VW's have the same flange and do fit the standard 8v heads. May be a low price option.

Turbo's
by Dolemite
The Chrysler ones are funky on the turbine housing and best left alone for the ease of upgrading later.As far as the turboi disel manifold goes.....WAY too restrictive,And if you try to port it it's gonna crack.If your doing an 8v,Buy a cast manifold,You can get them for a VERY reasonable price.and it's well worth it.

Turbo
by Kurt West
I ported my turbo diesel manifold and it works fine. The garret turbodiesel turbine housing is the same as a T3 so it bolts up to the manifold. Less stuff to screw up.
My car has a T3 runs 10 pounds with SDS EM-3F system with nitrous.

Turbo
by Chuck B (UFO)
The Volvo or Saab exhaust housing should fit on the chrysler turbo.That would make it fit to the 8vturbo.com manifold.If it's good and cheap'buy it you'll need to change the exhaust hausing though.

saab 900 turbo system for 16v
by Adrian
I am trying to get some info together. I am thinking of using the saab 900 turbo system for
a jetta 16v I have. Why saab? The system is bosch,
the ign. distributor drops right in. I am trying to find someone who has any knowledge or
experience with it. Is it a good choice ( or even the volvo.)

i have one better for you to try
by jerry
http://members.tripod.com/~vwturbo/gti.html
i will make a dist. for you. the vane air is bosch, use a t-o3 from a t-bird/svo/merkur. an aftermarket tuner that is completely programmable available($350) that will make you able to change injector sizes, all timing curves, fuel parameters, rev limit. everything. do that with a saab or volvo system. its easy. its up to you.

Headgasket thickness?
by Alan
Can anyone tell me the thickness of a standard headgasket for a 1.8 16v engine or tell me which thickness of copper gasket to get to lower the compression to about 8.5:1. I was intending getting the gasket from http://headgasket.com/ and the choices of thickness are .022, .032, .040, .043, .054, .063,.086, .093, and .125 inches.

Thanks in advance.
Alan.
