Hi, greetings from Finland

Some may know this car from Turbosport (or not) but here it's again.

Been in the family since new (-71) and taken out from the road early 90's around 122000km on the clock. It had monster 1.3l kent without any kind of luxury. I decided to take this project to be my first in 2004 and started take it to pieces. I did get it back on the road after long 8 years of building in July of 2012. It did get 13000km on the clock and then valve retainer broke and destroyed one piston. This was result of too soft valve srpings (kent cams hd, peace of shit, same rate as stock springs!) and original valve retainers + 7000rpm redline and heavy foot

There is so much pictures and story about the first build up, so here are couple videos to show the build and result of it in a neat package.


I'm rebuilding the car and new engine at the moment, can write a story about that and where I'm at the moment if someone is intrested

Thanks, it's been now almost 2 years after broke down so I'm very eager to get back on the road again and humiliate some newer car owners

It was cold december day when I decided to open valve covers to see what's broken and this is what I wound.


Couple other retainers had also cracks on them



So took the head off to see how much of damage there was





Some may think why in hell I'm still building same crap 2.8 engine? So am I Just kidding, to be honest one reason that is very difficult to get example 24v version by law to this car. And second one is that almost everybody else has lost their faith in these old 12v engines. So I wan't to be different and show that these can also give nice power figures too.

With the right parts and a very large turbo they can be very good.
What about a 2.9 12valve? Would that be possible?

Sultzi

I have two smallish turbos, Garrett GT2860RS rated to 310hp per turbo by garrett. But if these seem to be too small in this next engine I can always upgrade them to gtx version with same t25 flange. I have now also measurement on each manifold for back pressure so will see how these turbos start to restrict on the dyno. Single turbo would be easier and probably same or even better for drivebility, but I like symmetric things so need two turbos

For that 2.9l, that basically pretty hard too. I would need to use only the heads from that engine and modify them on the 2.0-2.8 block (for the inspection, basically I would have 2.9 bottom end, no one can tell the difference when mounted on the car). Don't see those 2.9 heads so good I would bother to do that.

Yeah, I have been following skogenrace cars for a while.

Here is small clip when the car was still working, slippery I think..

So, maybe I start slowly to tell you guys what is now happening with the car.

I decided to build completely new engine with hopefully better parts than old one had. I was driving with e85 only with last setup and when I was building the engine I where going to use just gasoline. So my cr was just around 8.2:1 (or that I thought, when I dismantle the old engine and calculated the cr it was only 7.3:1!! So small mistake from my behalf on that). That explains pretty high egt temps on cruising and smallish turbo lag in the low rpm's. So this new engine has cr at 10:1 with new pistons from CP, so more suited for that ethanol.

And here is some pics..

sold that beaten up cossy's t5 and bought new tranny that should take all the beating I can give to it with this crappy cologne engine


It's bmw GS6-53DZ which have proven to take +1000nm without hassle.. This has ratios like this


Mustang 2.8l bellhousing (or part of it) welded to tranny


Got electric power steering pump from 2000-> toyota mr2, this will be located to the trunk away from the engine bay.



Took the rear axle out to do little maintenance and also will change those lower arm mountings to better ones and hopefully get rid of that wheel hop. Also changed bearings once again.



New mountings tack welded, still needs some reinforcements..



Draw new exhaust flanges


New Howe master cylinder for clutch and another one for brake. (sierra electric boosted unit will be in the trunk also)


Got nice tool from isky, no more problems with head gaskets


Also some nice shiny pistons


These recuired some molding to the factory get things right



Block itself needed more rigid main girdle than before, so I modified one 2.9l made picture with solidworks to get it fit these 2.0-2.8 cologne blocks.


Machine shop did all the work





Small modifications needed to get the oil pump fit



Drilled and tapped m8 threads to the block oil pan line for more rigid girdle. I think this should take all the beating I will give to it. (main bolts are just temporaly, don't worry )



Will write more story later time, thanks
