Engine build progress

Spool-up of a K26/8 on a standard car sounds far from exciting to me, but we just have to wait and see once it's run in. Thanks for the feedback anyway. The downpipe originally touches the heatshield attached to the block, which then had to be slightly distorted to give some clearance just so the V-band clamp could be put on the downpipe. Once in the engine bay with the cross over pipe in place, there is even less room to "play" with than what the picture suggests. This evening we installed part of the exhaust.

The whole alignment turns out better than expected though further adjustement may be necessary as it gets very close to the left caster block.

You weren't expecting the LR75 to be quicker spooling were you? [&:] You'll get bags more boost when it does spool up [8D], but fitting a larger Turbo is never going to decrease the lag (all other things being equal)
 
No I did not, but the owner is sort of aware this is how it is going to feel and it's his choice. I would not have used such a big turbo myself.
 
The owner has tried to register to this forum last week but got no confirmation reply - is the administrator away for holidays ? Thanks.
 
Some pictures from yesterday evening session. Adjusting the air box.

Home-made connections for MAF sensor.

Fitting the intake manifold.

Everyting is finally assembled. Oil used for start-up is mainstream 5W50.

Engine is first being cranked without plugs, so that the oil goes everywhere it should. It started on first attempt. Some smoke because of wraps on the exhaust manifold drying up.

ORIGINAL: TTM Mark, thanks for the feedback. It seems the Super 75 can be had in several forms and the one used here is a journal bearing, "oil cooled", 8cm² hotside, T350 turbine trim. Do you know exactly which one you run ? Patrick, there is a 944 NA camshaft to begin with, he (we) will see how it feels ... Who would you call for a "bigger" camshaft ?

I'm not sure of who deals with this sort of stuff in UK / Europe. I do know of a few vendors in the US. The one I have was made by the same guy that did John Milledge's work in the US. It wasn't cheap but it is made from the ground up (or ground down so to speak) billet, not a modified product. Still with the strength of the Pound/Euro I would imagine approx 400 Euros? Only guessing, but I can say that it totally livens up your engine. I had the stock head/cam on for a while and then switched to the racehead/cam and it's like another turbo in a fashion. The car just wants to keep revving. The other good thing is due to relatively low compression with forced induction, it's not a total pig on the road like a big cam/high c/r n/a car. I love it. Oh, and congrats on the project and first time start up. Well done!
 
Patrick, thanks for the info. The car had an alignment done today (I did not mention it earlier but while the car was "apart" we fitted a KW V3 kit and reindexed the torsion bars) then went for the MOT which it went through troublefree. So far the owner has reported a well-improved throttle/engine response and the turbo can be heard spooling applying only featherweight throttle. Difficult to compare spool-up with a K26/8, especially since his previous engine was so much worn out that it never worked properly and drank almost as much oil as fuel - so difficult to feel anything but overwhelming improvements. [:)] A 600 miles running-in trip is programmed for the weekend.
 
Thom, Just looking at this thread, and am very impressed with the work you have done. It amazes me what can be done on a few axle stands by someone who has determination, and works to a high standard, compared to a Porsche centre where they need two technicians with gloves and a Car lift to look for a rattle. And if there was anything mechanical to be done they would need two attempts to get it right - not that it would be their fault. And you never use the word "Sir" in your comments[:)] You should be proud George 944T 964
 
George, thanks for the kind comment. Nothing to feel proud of really, just the simple satisfaction of completing a project. The critical part of the engine - the bottom end - was already assembled so all in all it was pretty straightforward. If we had been better organised we would have been much quicker ; we had to stop several times because of minor parts such as bolts & rings that we had put somewhere during the strip down and which we never found back - also don't mention the constant mess on the ground ... [8|]
 
Well done. Truly impressive. Is that the Rennbay fuel line kit I spy in one of the photo's or just heat shields over the fuel lines?
 
Scott, this is the fuel line kit from Lindsey Racing. The silver wraps that go over the braided fuel lines are supposed to protect them from heat. It would have been nice if they were available in black instead of that dubious grey ...
 
I've not seen the Lindsay kit. Will have to take a look as i'm considering a similar thing as I think 20yrs is more than enought to ask of the original fuel lines, and stories of a few cars in the states bursting into flames possibly as a result of those fuel lines rupturing due to age has really got my attention. In fact I quite fancy the Lindsay fuel rail kit. NOt only does it look nice but it operates alot cooler which has got to be a good thing. What with the KW installed that car is just about what i've got planned for mine. I've just got the big valve head, MAF and larger turbo to go. I will be insterested to hear how the owner gets on with it.
 
Scott, here is a couple of pictures of the hoses. The quality is pretty good (the hoses, not the pictures [8|])

As for the LR fuel rail, for what it's worth the previous owner of my car fitted one and it has worked troublefree from day one. It seems some guys in the US have had problem with the FPR supplied with it but that has not been my case. I regularly check fuel pressure anyway. I am not sure how it would operate cooler - even though there is no rubber around the hoses they still hang above exhaust manifolds and get pretty damn hot under even normal use. Wrapping the exhaust manifolds as done here is a good idea I think.
 
They do the rail kit with an adaptor for the stock Bosch FPR now which is the one i'd go for. It is the actual rail that operates cooler that i'm referring to. Apparently the stock rail gets quite hot when the engine is running and warmed up. Apparently the internal diameter of the fuel manifold is much larger than the stock manifold so more fuel flows through it which keeps it and the fuel cooler. Apparently it feels cool to touch when the engine is running. This has got to be better for turbocharged cars. The only possible disadvantage i've read about them is that you can hear more injector noise than stock. Thanks for the photo's though. All looks good.
 
Without the fuel damper a "tik tik tik" noise from the injectors can be heard. With the fuel damper fitted it can only be heard at tickover.
 
We enjoyed a terrific running-in trip in central France last week. I drove Sly's car and yes, with 1.0 bar max peak boost it feels very much like a stock K26/8 car, only with PW/TQ curves scaled up. It should be great fun once the running-in is complete and peak boost is set at 1.2 bar.
