So I've been doing some reading on forums and binge watching videos .
I'll get some more info on a car in my price range next week . It's a 124 estate which means a om602 engine .
My end goal is in the 400 hp range with the very rare full power drive .
I see two options right now . Change the head or just buy a turbo engine and modify that .
I'll have a stab at redoing the pump myself . 7.5mm on that with ALDA .
Inlet and exhaust manifolds will be changed .
And a GT3071 with water cooling  will be used with an external wastegate .
So for the stock engine oil feed for the turbo will be from the filter housing and dumped in the sump .
But what about the water cooling for the turbo ?
And what size intercooler can you fit and keep the AC ?
How much does the powertrain on those hold ?
Cheers

Anybody have any experience with FCP rods for these engines ?

So,
slight progress to report .
An OM605 turbo was bought on the cheap and is now proudly weighing on a cart in my garage . Came up with a super simple exhaust manifold which I'll show a bit later .
Also a simple design of an intake is on the way .


Still no car to put it in, though I'm working on that as well .
It's gonna be a 124 estate .

So some questions :
Will a 53dz gearbox fit in a 124 tunel behind a 605 ?
The shifter will need modifications, that's clear but I'd rather not drill/cut.beat up the original tunnel .
Anybody have experience with a s200sxe with a 0.82 AR ? When can I expect boost ?
And will the stock 411 box hold about 200hp ?


Edit :
Some pictures of the intake and exhaust
   
   
   
   

It's a two piece construction  . The bottom pieces are 20 mm thick and use a gasket from a 606 . the seal to the top piece uses O rings . And the top piece is attached with three studs to the bottom pieces .

   
   
The exhaust is just flat stock laser cut to fit and the space in between is made from 33.7 90 degree beds just cut up and welded together .

Some more pictures .

Since I'll e doing my own pump I started with the ALDA .
   
Using a valve spring from an old head on a 40 mm cylinder gives proportional
to pressure travel starting from almost 0 bar . It's linear to 5-6 bar . Haven't measured the travel mm/bar yet .
To my mind it should keep smoking very low as the pressure rises .
And the slots allow for some fine tuning on how fueling picks up as boost is applied .
   

Here's a photo of the intake side 
   

And the exhaust manifold
   
   
   

Still waiting on the flanges and aluminium parts from the laser guys . Will have some practice TIG welding aluminium .

Very nice!

Anybody have any experience with the stock single mass sprinter kit ?
What torque rating can it hold ?

Ok,
since I have a body to put the engine in it's time to think about intercoolers .
These two are easy to come by, but does the 180 fit in in a 202 front while keeping the AC ?
