View Full Version : Project Bmw 345i Turbo.

04-18-2004, 11:46 PM
This might be helpfull for those who have plans about turbo in there E30... My engine is a M106 and comes in 85mod 745i. 3,5liters engine with original boost about 0,4bar (1,0bar is 14,5psi). My plans are to get as much output as possible at 1,5bar (21-22psi). I'm hoping for around 650hk... Here are some pics of the project.

Looks awesome! I would love to see how it progresses.

04-19-2004, 12:12 AM
NICE! did you do all the custome piping?0

04-19-2004, 12:15 AM
holy crap man thats crazy

04-19-2004, 12:35 AM
The piping is done by a Swedish man called "Bäckis". It's his turbo I'm jusing. The turbo is a Garrett GT42, and is made for 800hp!! At this time, "Bäckis" are tuning my engine...

Here you can find his car i action (with my turbo)

http://www.sbr-racing.com/ -> Filmer -> bmw 9,5 repa

If I can get 650hp, I would get around 900nm.

The teoretical toppspeed would be around 325km/t (200mph)

I'll try to keep the progress uppdatet.

Sorry for my bad language (it's been a while seens i left school)

looks great ! what about Hartge? Do you use any Hartge components ? you call your car Hartge. please tell us about internal components: which brand piston, engine management, compression ratio etc....

04-19-2004, 10:58 AM
The car is a Hartge H35-254ps http://www.schwarztwo.de/e30/fotost/f01015/f01015.htm

But seens the Harge has no turbo, it was reabuilt in the year 2000. Then the engine from a 745i was fittet. The engine is called M102/M106 and are simmular to the M30 by looking at it. But it's got different pistons,turbo, stronger exhaust valves, oilcooled pistons and the compression ratio is 8,0:1.

The engine has 252hp /380nm originale, but by installing a chip, you get around 400hp and 520nm.

I hope I can get the car stripped down to 1000kg.
I now have to install a rollcage so the car don't giv in for all the nm...

04-19-2004, 12:51 PM
that's... a f_cking, huge turbo.

04-19-2004, 09:46 PM
that's one sweet e30

that must cost you a fortune
nice grill at the front

look at that engine :-)

Here I am at a streetmeet...

I took apart the engine today.
I'l come up with some pic's in 15min.


But I'm going to juse this front when the car is finish. This gives more air to the Intercooler.

04-20-2004, 07:39 PM
cool red car that
are those the much talked about angel eye E30 headlights?

04-20-2004, 07:46 PM
Here are some pic's from my garage today. The engine is now ready for some changes...
This is one of the strongest engine ever bulit by Bmw, so I hope for an engine who can handle much output over a longer time.

This is were the exhaust will come out. 4" pipe.....!


04-20-2004, 07:58 PM
wow. looks amazing. ..

for those that can't see in the dark...

04-20-2004, 11:20 PM
The exhaust systen from the engine will have one small silencer.

Insted of piping the wastegate together with the exhaust system, I'm going to pipe it in separat system, with no silencer at all.

It's going to be a 2" pipe, and I'm letting it out on the oposite site of the engine's exhaust.

It's gone end in 4" like the other one.

Then imagine the sound from wastegate-exhaust on full trottle. When the wastegate opens max on free flow with NO silencer.

When I let go the pedal, it's quiet again.

Get it?

I'm sorry for my bad language...

04-21-2004, 04:27 PM
Jasså, det er noen flere normenn her!! HEHE

Heftig turbo!!!

Kommer vi til å se denne bilen in action i år eller??? Du rekker Gatebil på rudskogen... Hadde vært virkelig morro å sett den!!

04-22-2004, 12:06 AM
Gjør ikke regning med å få den ferdig før Juli-treffet 2005...
Med det hadde vært morro om den ble ferdig før...
Skal inn å skremme Ruud Racing litt!!!

Here's a pic of the car before a started tuning it.
The output at this time was around 400hp / 520nm.

I'm having a new radiator spesial made fro my car. It's a "as large possible" type of radiator. Made in the same design and style as the intercooler.


04-22-2004, 09:21 PM
Så på dansk :)

Findes der ikke allerede en magen til i sverige med samme seidl-tuning front og kæmpe turbo ??? Har set billeder og film af den på nettet den kører med 19 tommer fælge/hjul...

04-22-2004, 10:01 PM
Yes that's right! It's a friend of mine. He's one of those who's trying to help build my engine. He's made my manifold.

Here are some pic's of it.

Output is 750hp+++

I've got a video with it, but a don't know how to host it...




09-11-2004, 06:01 PM
Now here are some uppdates.

I've now got my engine back from Sweden.

I've bought some stronger.... That thing who holds the piston.

The engine is now weight-ballansed.

The turbo was not big enough, so I bought a bigger one.
The new turbo is capible of 1100hp.

The intercooler was not big enough either, så I bought a bigger one.

I needed a bigger trottle-house too. The new one is 80mm (3,15")

The fuel-pumps are bought. It's two Bosch pumps. They can manage 1200hp together.

The cylinder-head is also finished, but I'm not getting it until next weekend.

I'm now making the engine ready for output over 1000hp, but I'm expecting 800-850hp / 1000-1100nm torqe. But the output is with regular 98 fuel.

Here are some pic

The intercooler on the pic are still in the donor-car.
It's the Swedish "Bäckis" car... Bmw E21.

09-11-2004, 06:22 PM
Can you come by my garage when you're done and do my car up too?:D

09-11-2004, 06:25 PM
WHOA ! keep posting more pics man ! SHITTT

09-11-2004, 06:29 PM
:eek: *mw* wow

09-11-2004, 06:29 PM
dyno that shit and tell us the power!

09-11-2004, 06:38 PM
I'm gonna let you know when it's finish.

The engine is now capible of 8000rpm.

If I take the engine all the way to 8000rpm on every gear, the speed would be:

1. 80km/t 50mph
2. 140km/t 87,5mph
3.220km/t 137,5mph
4.320km/t 200mph
5.385km/t 240mph

I suppose the topspeed are around 330-340km/t 205-215mph

The boost is gonna be close to 2bar (30psi) now.

09-11-2004, 07:47 PM
Absolutly incredible.

09-11-2004, 08:00 PM
Very nice car..

09-11-2004, 08:24 PM
That car is fittet with M50/B28 now, and 1000hp on metanol.

I'm heading for PPF next weekend to collect my parts.

Nobody knows Bmw like PPF.

I by the way run a shop called Pure Performance Import (PPI).

I sell parts for Pure Performance Factory (PPF) in Norway.

It's a good marked for turbo-converting bmw's i Norway.

09-19-2004, 03:46 PM
that looks good i am also building a 335is turbo it should be done in a few months i will be running 400+ RWHP and 450RWTQ not 100% sure but i have a lot of head work and 20psi with just a chip and stock wireing harness.


09-20-2004, 04:29 AM
Hartge: What are you going to use for a Diff!?!?! I saw in the PerformanceCar BMW Mag the black 325 with the M3 style guards and the 875hp S38B38, mmmmm, was using a complete E28 or 34 rear subframe/trailing arms thus the massive rear guards.

I'm putting a Supra LSD & axles/CV's into my E30 which should be more than enough for my proposed 400rwhp.

09-20-2004, 07:22 PM
with all that power what have you done to the diff,rear subframe,ect

09-26-2004, 05:30 PM
I've been playing with the idea of building a 335 turbo for a while.Yours is the second one I've seen now.Looks awesome,love that intake. *love* now you've got me thinking again.
