Some earlier pictures of parts and the car the first time it was finished.
1008cc nozzles and som ARP bolts



Manifold form sweeden


Powerseteering



304mm breake discs


Allmost finishd, and ready to maping




402hp and 553Nm on wheels



And now the car will be picked in pieces again, to be painted in a different color, and be built together with attention to "finnish" and exhibition. But the car's supposed to be used =)







I have made new 3" downpipe


AN-4 on the turbo oil line




Break sylinder and hydraulic break servo from BMW 745


I also goint to use oil pump from Z20LET
As you can see there's much difference between the oil pickup in c20let and Z20let oil pump.
The flange on the pump, and the pipe are much more powerful on the Z20let pump.




You can also see the inside of the pump is different

Old C20Let

New Z20let


I am very curious to see how the new oil pump works, there are few that I know of that have tried this before

[corsakid]

the pump will flow more a very good mod for any c20let or c20xe etc

[Kadett C20let]

I hope so, but no one I have spoked with before can confirm that in other way then "I have read it on internet"

[Tathan]

very nice.

z20let is quite a common mod over here, the internals are machined from solid steel rather than sintered I think. Flow wise, it can supposedly flow more BUT:

Pressure is a caused by flow
Pressure is controlled by pressure relief valve
You can't have more flow without more pressure, so the pressure relief valve opening point is more important than what the pump can flow. A C20LET pump can flow more than enough to maintain pressure at all engine speeds so there is no point trying to flow more.

Benefits though:

I'd guess that it is a bit more efficient so less drag
it's safe for higher revs

[corsakid]

nice turbo though engine makes good power what bost level did it make 402bhp

Ahaa
Have previously had problems with the original C20let pumps.
Begun to create bad press the hot engine, and takes a long time before the oil lamp goes out when the engine is cold. Scary to start to wait for almost 5 seconds before the lamp goes off. So here in Norway we have a lot problems with the original pumps. But most people here buying intensified parts from SBD, but that eather not hold forever

[Tathan]

Yeah the SBD part is a copy of the sintered gears that is machined. Sintering is cheap and light but not particularly good. Not only does it wear more quickly, but it is very brittle and doesn't take that much to smash to pieces.

This is the SBD gears. The engine was running about 10 hours before this happened!

[kadett kinin]

isnt the getrag 265 from a bmw? what model? and did you swap the bellhousings over from a manta 1800 getrag 240?

[kadett kinin]

oh yeah and by the way that car is gorgus!!!!

[TigraTurbo]

ACE.............

It is true that you can find Getrag 265 cases in some bmw`s. For example, bmw 765, 635ci, etc.
But these are not identical to those used by GM, (Opel monza/Senator 3.0i)
The flange from the gearbox is not equal. On the bmw is a tightened rubber "hardy" link to the shaft, and on the opel case are the only regular splines that are slipped into cash like the getrag 240.
To get manta 1.8 house to fit, I have made an adapter plate that sits between the house and the gearbox in 20mm aluminum

oh yeah and by the way that car is gorgus!!!!

ACE.............

Thanks

[Kadett C20let]

Btw. Here is a picture of the Volvo 240 rear axel I use.
3.71:1 in gearing and diffrential breake from sellholm in sweeden.
I have build it to 4x100mm and welded on some mounting bracketst that fit in the orginale boltholes in the flor.

[Kadett C20let]

And here is som pictures of the hole car and the brakes mounted.
The car will be painted in LY3D (Vw tornadorot)
The car will be painted below, inside and outside.
Wheels and the rollcage and everything else like suspension becomes black matt

[kadett kinin]

was the imput shaft not to short? and did you need to uprate the gears to take that power?
Sorry for all the questions.lmao

[Kadett C20let]

Questions is just fun =) I am happy to answear

No, the input shaft is not to short
I use the orginal gears with no problems.
It's probably have something to do with the weight of the car.
I have no grip on the backwheels on the asphalt before the 5. gear (that`s with regular street tire, with slicks it helps alot )

[kadett kinin]

thanks for the answeres!

[Kadett C20let]

thanks for the answeres!

You are welcome, I am happy to help

[djivesp]

Oh my, that is awesome
That engine bay is porn aswell

no wonder when you see the how the axle is hung

[rc]

Wow now thats impressive 553Nm through the rear wheels, scary

[kwkmanta]

Thats one wicked project.How does the back axle handle the power with it being mounted like that? Ive got a chevette estate im planning on putting a saab turbo lump in and my piazza axle is alot like yours.Might have a go mounting it the same as you if it works well.

No, It`s not scary, its fun

Well, it's far from optimally mounted, but it works fine, and I use the original mounting points on the floor, and saves a lot of work that way.
So I use it as long as it lasts

When it breaks, it will be 4-link
