A saab TDO4 turbo on my CA trouble with exhaust housing

ok guy these r the pics of my turbo

after seein the turbo can some one answer my questions

[zero_gripS13]

the oil feed lines orrientation does not matter as it is pressurized, but u want it to enter the turbo as close to 12 o clock as stated just to clearify.

[jbracy7]

could you just block off the smaller inlets and use the larger inlet alone

[carim000]

no man u can not block the inlets ,and the larger inlet is an outlet which the down pipe is attached to.

Its a very strange turbine housing setup. Okay for a v6 or something but not exactly ideal for an inline 4. You might run 1 and 2 into the forward facing one and 3 and 4 into the rear facing one. Looks like because of the setup it might be a little laggy though. How big are the inlet flanges for the exhaust, just to give us an idea? They look kind of small.

[carim000]

they are small, ill measure them today.

I guess for karims good fortune the holes are thin in size, this might cause some pressure by the exhaust manifold so low spinning would be initiated... but the annoying part comes when it spools up high, the inlets could be a little limiting to the flow...

I guess it would have been better if you'd get 1-4 then 2-3 into the exhaust turbine, since that will cause even more high pressure which will cause the turbo to spin up faster on low rpms...

But then thinking more about it, the turbo came like this on a V6 2.8, so I guess the inlets won't be restrictive on high rpm, but it will definatly be laggy down low... but the question is how laggy would it be?!?!

The T-25 in karims car is bearly rotating, it literarly hurts ur fingers before it rotates and it still openned up full boost on 3800 - 4000 rpms... so I guess the TD04HLA 19T would definatly open up at around 4500 rpms MAX!

IMO

ok i just measured the 2 inlets and each inlet is 28mm in diameter.i measured the inside of the inlets.

and i am using 38mm pips which will come out of the head.then each 2 pipes (1 n 2)or(3 n 4)will be connected in to one pipe goin to the turbo inlet.

any comments?!?!

Go for it man. We won't know for sure until its in and running.

[carim000]

ok the manifold is being made with thick stainless piping.i will try to take pics soon and of every thing.

my car is a stock ca18det with a 3inch exhaust and now (hopefully successful ) a tdo4hla 19t and a custom turbo manifold.i have no fuel management system ,no apexi safc, nothing else.

Without any tune and at low boost(0.5 bar) would the car run properly with the turbo i have put?!

[r34 gtr]

Maybe? I don't know, that's a sizable turbo. 7psi on that will be a whole hell of a lot different than 7psi on the stock t25. Would you be able to have it rom tuned any time?

[hydra]

Dude, a 19T is a little smaller than an S15 turbo as far as wheel sizes go, but has the equivalent of a 0.48 A/R housing just like the stock turbo... I don't think lag is going to be all that bad...

[carim000]

the car has been running for about a month at 0.6 boost, the car is more powerful now then wat it was(stock).

the mods are 3 inch down pipe ,3 inch exhaust ,2.5 inch muffler(i need a muffler),custom turbo manifold ,TDO4 turbo (0.6 boost), stock inter cooler ,no tune.

i raced a civic type r 2004 from a rolling start of 60 km and i was infront of the type r by 3 cars.is it a good result for wat i have on the car??

i will post the pics of the custom turbo manifold soon ,and ill upload the video of the race too.
