turbo pics

[bbeck]

how about some pics of projects or completes and details? that way it will put alot of info in one place.

[Berettaspeed]

well alot of people have seen these, LOL but here goes.

[bbeck]

looks good man, how much do you think you'll have into the turbo conversion total? and what did you do with the rear exhaust manifold?

Hi, this is my project almost ready. It has a T3/GT40(Blowzilla) Turbo, and 38 mm Tail waste gate, 50mm Tail blowoffvalve, 65Lb injectors, Stock internals with a copper head gasket to lower the compres and the best thing is I swapped a Beretta gearbox so it's manual now
Big front mounted intercooler and 3 inch exhaust with no muffler yet.
the heads are race P&P with SS valves and LS6 valve springs.
Waiting on stage 4 clutch and the tuner don't now yet what to buy??( DHP or HP tuner or a Microtech)

That's real pretty, I think you may run into problems with your injectors if you are planning on less than 400 hp. I have been running injector requirement specs in this calculator located about mid page:

http://www.rceng.com/technical.htm

and at 400 hp with a high BSFC of .65, 6 injectors @ 80% duty, and 50 psi fuel pressure and the recommended injector flow rate was 50.5 lbs/hr. Your fuel pressure will likely be higher than that if the regulator is connected to the manifold under boost.

Just giving you a heads up in the event you are not aware of the problems some have had with comparatively large injectors and getting them to flow a small enough fuel amount at idle however if you have sequential fuel injection that will help.

Hurry and get it done, and post video with good clarity and NO MUSIC, it makes me sick to open up a video of someones project only to find amateur audio/video efforts edited in, contaminating the sound of a pumped up engine and tire chirping. JUST SAY NO!

Oh ok , Today I will get the car back from the muffler shop so, then I will be posting more pics.
MMm right now I'm going 10 psi boost but later when I have every thing good tuned I will be going 15psi. Lets see how much WHP I can get out of it. The est WHP will be 375 maybe with my set up. But if I ran in to problems with the injectors, I have some 42.5lb injectors to so If the ones I'm gona use right results to big then I will change them to 42.5lb. Btw I have the intank wallbro fuel pump (255lbp )High pressure))and a Earomotive fuel reg with boost ref.
But I'm still deciding what tuner to buy.

[TurboAlero]

whaha don't worry I will be posting some video when all is ready (Without music ) lol.

[Joseph Upson]

I would start with the 42 lb/hr injectors for sure at 10 psi boost since many are running that much boost with stock injectors or a little bit higher flowing. Your turbine housing looks pretty big so I suspect boost will come on a little late with peak efficiency up in the high rpm range looking at the compressor. The intercooler will do quite a bit of justice as well.

15psi on stock internals it better have a good tune

look into megasquirt possibly yet?

i like it tho

[IsaacHayes]

Got stronger pistons or stock? Stockers can't take much over 8psi... So the getrag 5spd bolted into the subframe or did you have to make some mounts? Cool, I don't see many newer cars with 5spd swaps!

Syn: with ODBII he can just use a DHP powertunr and have a nice GUI interface to edit his computer. And scan all in one.

[TurboAlero]

mmmm, the bolting of the Getrag went very fast, because I just use a part from the chassis of the beretta, the driver side upper suport frame and , I'm gone use to supports from a 3.1 lumina (the 2 upper supports that will bolt on the frame above the radiator).It's was a little work but not impossible. For the axels, I'm busy with them right now but I will have a better update for you guys later on, But till now the passenger side axel will fit (the stock Alero axel) and the driver side I still have to see tomorow.


For the pistons they are stock , I know there are people pussing more then 15psi on stock internal, so till now I didn't hear that someone pop't the stock pistons. But still they are stock lol!! I think they will holdup fine for 10-13 psi boost max. later on I will upgrade them to forge.

[TurboAlero]

for the Turbine housing They told me that It will spool very fast, because these engines have allot of output(exhaust pressure).But it's not so big it's just a T3 housing with .82 a/r and it's ballbearing. But let's see how it will performe. Hopefully I will start the engine tomorow. But just start, I'm still waiting on the tuner.

[Joseph Upson]

The stock pistons should be able to handle quite a bit based on a stock 32 vavle mustang V8 article I read resently by a company that outfits mustangs with turbos. They were well into the double digits on stock pistons and compression ratio but the engine was tuned properly particularly where timing was involved avoiding detonation and using racing gas at certain high boost levels. I'll try to find the write up in which they made it clear at least for the stock mustang V8 that failures on stock blown engines were due to tuning deficiencies much more so than the stock pistons.

In GM's case there is the issue of piston slap that apparently has to do with there selection process in the 3100 and 3400 I believe, mainly affecting pistons #5 & #6 hince the single oil squirter combo at that position on the 3500 block instead of all 6 like in the 3900 block. Even without detonation if the cylinder pressures are building to fast due to persisting overly advanced timing they can still fail.

I'll try to find the article because it was quite encouraging.

Some might bring to light that the ford has hypereutectic pistons, but given the alleged limited steel crank debate and the 3500 V6 the bottom line is none of us really knows what the pistons are made of given the inconsistencies of GM information regarding their own vehicles and since a replacement piston was released to tackle the piston slap issue that resulted in failure in some instances it is very likely that it was made stronger. The new 3.6 DOHC VVT motor in the cadillac has forged aluminum pistons but GM documentation does not always mention that, I have only seen it once. I don't believe it and the 3.8 are the only ones that have received forged pistons in the same manner that the Buick Rendezvous or Terraza was not the only 3500 V6 engine to receive the steel crank which according to one of my engines was being installed in the 04 Malibu contrary to what their literature would suggest.

Pump'em up with good tuning and we'll all know for sure.

.82 is boarderline for 10 psi in your engine and 15 psi will be fine only in the 4000 rpm range before you run out of turbo. To much back pressure will hurt your power as well as likely promote detonation so start conservative. I will be installing a pressure gauge on both the intake and exhaust to monitor back pressure and make sure it doesn't get to high. I believe optimum is a crossover point where exhaust pressure exceeds boost pressure near the engines peak efficiency point. Sorry about all of the posts but this is my favorite subject.
