Alright. All of the pictures are probably taking a while to load so ill give a quick explanation. I bought this car for 2 reasons. To
A) have a fast car
B) have something that you dont see every day
When I bought the car I had a lot of ideas for what I wanted to do in the future (procharger, maggie, etc) but really left the turbo idea out of my head for some reason. One day I looked at the details on a turbo kit for the GTO; which led to my intrigue. I found there only to be 2 way people usually turbo their GTO's: APS and STS. So of course I looked into the 2 options, and pretty much was focused on the STS because of its simplicity and easy access. I also looked at the pricing which kind of deterred me (being a college student). So I was kind of stumped as to what to do.
I finally just sat down one day and decided (with the help of my good friend Carl H) that a front mount turbo would be rare, relatively cheap, and would be putting out the same power as any entry level FI GTO. (500-550 whp). Now with the first reason I bought the car expanded, I looked at the rarity factor. Front mount turbo GTO's are few and far between, but I have yet to see a HX55 turbo used in any of these builds. So after doing some research I decided to roll with that idea.
Now the pictures. Ill be posting up pictures throughout the process and explain whats going on. This is by no means a "how to" thread because I want to try to keep the car original, but I will answer any questions asked and will be open to constructive criticism from any offered.
On to the pictures.
This is the heart of the operation. A HX55 for a 12 liter volvo semi truck.
Here are the "super secret" specs from Holset. I had to actually email a guy in the UK to find information on it.
The compressor inducer is - 65mm
The compressor exducer is - 98mm
The turbine inducer is - 86mm
The turbine exducer is - 72mm
The turbine housing critical area is - 19cm2
Now since you cant tell how big the turbo is from the above picture, Here are some more pictures with something to compare it to.
Now the parts ive bought over the past couple of months:
Truck Manifolds
Turbosmart 45mm Wastegate
Greddy Type RS Blow Off Valve
Walbro 255
Just threw it in without taking pictures...but im sure you guys know what it looks like.
650# injectors
Our current plan is to chop the truck manifolds and weld on V bands. The manifolds will be mounted upside down. The passenger piping will go round the front of the engine, and the drivers side will "J" up to the turbo.
The downpipe will be made using oval piping to avoid "massaging" the frame rails.
One of the first steps to getting this thing started was buying the Turbo. Carl and I were driving back from college and he had talked about stopping at a turbo shop in the middle of nowhere. Driving up was sketchy, but after talking with these guys for a good 2 hours we were pretty comfortable with them. So I ended up walking out with the turbo after chatting with them about my build.
The next step was my clutch. Of course the stock clutch (with 50k miles) wouldnt hold the power I wanted to go for. So I found a Spec Stage 3 Clutch from a member off of this forum. The install took 2 days. Yes 2 days. Main problem was the Pilot bearing basically seized in the engine. We had to try 3 different tools to knock it out. Overall if that little snag wouldnt have happened it would have been relatively quick. I also found out my old clutch and flywheel were pretty much spent.
And the new spec stage 3 Plus with a flywheel.
