Bmw E30 - 8sek hunt - Daily driver
Hi All.. iam at other bimmer forums with my build thread.

so why not here to !

A bit of info on the car then for those that havent had the time to see the green "hulk" before.

The car then.

BMW E30 2door
plastic hood and trunk, and plastic windows in the back.

M20b25 Drill ø stroked to 2.7L
Ross Pistons
Custom rods
The head is an standard 2.5 with crmo retainers, stainless steel valves, and heavyduty rockers
and PPF camshaft

Its making 646whp and 832wnm at the moment
With this power it made 9,6 and 235kmh at the 1/4 mile

And this is with split rear end and a zf gearbox

Now the target for 2011
The powertrain will remain the same, the clutch setup will be changed if necessary.

The goal is to hit the 8sec on the 1/4mile, to this then will need more than 646wheel horses.

These components will be changed

Fuel system, Turbo, cam, injectors and then new pistons

the fuel system for this year will be completely from Weldon racing pump who is also a new sponsor for 2011

fuel system
Weldon 2345

Weldon 2047

Filters also from Weldon.

And for the daily driver setup will need an Weldon Fuel pump controller
(this will make the fuel much colder and also so the pump wont run att 100% all the time)

injectors will be bosch 1600cc
Turbo and cam is not clear yet, but its between a PT71 or BorgWarner 375 or 475

More to come:)

/ Karel

But today we had more speed

I went by My motorguy to help him out, i changed the bushings in the rods to a much harder and better ones.

We made an rigg for the injector sockets

Johnny keept on welding up the intake

Johnny then moved on to the turbo pipes, dident say a thing during the evening and the it was finished

I did start with the wg pipes

update Time.

Its been quite for som time.. and that have sucked..

All of the stand still has been due to the motor guy has to much to handle on 1 person.
But now it seems that the speed is upp again.

The new bearing is sanded

the engine block is flattened

Drilling the engine block

Milling for the steal thread

Hening the last of the block

When the head got welded it got a bit twisted

A friend of mine wanted to try a new foil he got home.. so i voluntared :)

Jocke started to lay down the foil

A bunch of friends got over to se the final product

Hopefully im putting togheter the engine block tomorow and this weekend its going in.

karel 05-20-2011 03:39 PM

New day new update

Started by putting the bottom end togheter at Engson the motor guy
Grindning the piston ring gap must be the most boring thing one can do !!
