Well Tubby was kindly droped off on Saturday for me. I think you get the idea.











Should get me motivated to get this thing rolling

 

Don't you have carbon apex seals in that engine already?

 

No not yet. I have the seals here already but not got around to building the engine yet. Was getting all the ancilleries done before i built the engine. Kind of fortunate really would have been a bitch if i had rebuilt it with carbon seals then strapped a turbo on it wold have ment stripping it down again. Just regular tips going in now. Maybe SCR ones.

 

Manifold in the process. Not the most atractive welds compared to other stuff i have done but strength is key when you consider the heat cycles this thing will go through!!!

 

all TIG'd up



3.5" down pipe. Need to make a 4.5"-3.5" reducer for the turbo vband to down pipe

 

Strip down time. Decided to get the lump out and investigate why the rear rotor has no compresion:



Few of the block out with the tubby and manifold.















Some shots of the modified ports. These are the smaller of the inlets. Not attacked the big ones yet

 

Look at this sexy BEAST!!! Keep up the Good work Its others inspiration

 

Looks like it's coming along beautifully!!
I'm guessing your exhaust porting is bigger than standard from the size of the manifold??

I'm part way through a S5 20B conversion currently and loving every dollar draining minute of it! But I'm completely insain, so you get that =)

By the way, what turbo are you running? Looks bigger than mine, which makes sense if you're running larger ports.

Thanks for the pics - you've prompted me to pull my finger out and post my own! hehehe

Cheers

 

Cheers for the kind words.

I think you kind of have to be a little insain to take on a 20B project anyway! The turbo is a GT45 after checking with Garrett. Yes the ports will be modified when i get the new housings.

cheers

 

One of a couple of reasons for loss of rear rotor compression. Not the best pic because the camera is *****. Anyway you can sort of see all the coner seals, side seals and Apex seals are all firm welded in place. no protusion what so ever. with A LOT of paticence, time and some modifications to a few tools i did manage to free the rotor of its semi perminant seals. Then with planty of checks and huge amount of cleaning its all ready to go again. Other problems look to include oil starvation of the rotor bearings. 2 oil control ring o-rings were no where to be seen!!! totally gone. Not good.



cleaned





Still investigating reason for oil starvation.

 

Just realised that those 2 pics are the same!

 

Look, I know I'm getting on in years, and the specs do work, but I'm pretty sure you said someone welded the apex seals in place? I mean seriously, wtf?! What sort of moron would ever think that'd be a good idea? Unbelieveable, and definately one for the books!

Good luck with the rebuild!

Cheers

 

I just stumbled on to your project, looking very nice, I think you're correct you have to be a little crazy to take on one of these projects.

here's mine

BigAl...

 

Agh sorry i ment with rush/grim/heat not literally welded as in it a TIG tourch Man if someone actually ever did that

 

Hahahah! You had me wondering

Well, I've posted my FC thread! Do check it out =)

Had alook at this fella made project.

 

more on the better designed plenum. The other was a tad boxy for my liking. Possibly a little large. Anyway waiting on the flange so i can get it on and finish it off but :

 

thats sick it looks awsome

 

FULL strip down ready for the slow reassembley. Starting with the first phase of paint.





After primer and first base coat of white.

 

I love watching projects like these come together, maybe you already answered this but what color are you having the car painted?

 

White base with xirallic green over the top. Then my own custom green pearl wheels (see EGI project in N/A forum) with the same pearl green strip over down the middle. Sounds tacky but wait and see. She'll look grest.

 

Now she is all white i don't know wethre to do the lips of the skirt and front bumper black or leave them white. Still green next

 

Righty people. Painr is done..... bar a damn good buffing. No perfect but it only has to be a 3ft car as its a racer not a shower.

Here we go











There are a few defects here and there but hey. turned around quick enough!

 

Love the stripe and rotor graphic. Looks great.

 

rotor graphic is awesome!!!
