There short video of my project car:

I still have some prolems with idle and some oil leeks. But soon i think it will be ready

I assembled stimulator and it worked strat away! After that i started put together ECU and offcourse problems started First i had problems to instal and make working Serial communication (usb converter). But it works now. After that i soldered Input section and when i start to test it i cant get RPM working . MAT CLT and TPS from stimulator responds well on Megatune but no RPM! I soldered PWM cicuit cause i will use original PWM idle valve. I checked everything 2 times. Jumpered D2 diode but nothing RPM dosnt work . Maybe some one had this problem before?

2 days ago i recived my MegaSquirt ECU. It is MS2 PCB V3 with belectronic boost control. I got it unassembled so i can learn about it bit more.

Here is my delphi 37lb/hr injectors. I just heve to gett conections for them. I just wondering I heard that some GM cars 2001+ use Delphi injectors. May some body know wish cars,cause i was in scrap yard yesterday and didn't found smiler ones.

I read in some places about head modifications what privent haed gasket blowing. So i weld my head as well. When i took off head i so that gasket edges near water galerys was allready black and was allmoust ready to blow. So good thing i took head of

Here is my inter cooler. I know its not big but i think it will bee good for 250hp what im planing for begining.

Hi. I'm back with some update. It was long time i did something with my project. I don't own the car any more but i still have tu finish my project. I had to move in to another hause and garage thats why my project fas freeze fore a wile. But now i'm back and i've to finish this project as soon as possible cause big car show event is coming up.

So here is my full 2.5" egxaust system. Half of it is stainless steel and those bends is from truck shop. I did weld pipe to eghaust manifold for 38mm waste gate.

This is a skyline performance radiator which fits perfect between shasy legs My friend had it and i got it very cheep!

Fuel pump swap to walbro.

Here is oil cooler and Mercedes diesel van fan!

why i cant post in e30tech.com . How long i've to wait till they will let me in?

Wow, choice car mate.

I have a question though, what are the specs on the brake rotors? Just wondering what the dimensions of them are ie bell height, thickness, OD? I'm guessing 16" wheels are necessary to fit over the whole package?

fantastic - welcome to bimmersport, where are you from?

Hi there,

the stock bottem end is good for 450-500hp.or so various forums say.(good condition block)

a guy in the states has an e28 525 that sees 25psi often on a stock engine.yes he has

the head off every 6 mnths,but does good numbers.

it really depends on what your lump's condition is,milage etc.

and how much boost you want to run

i've currently got my second turbo project on the boil.

if you have Q's, PM me your number

ps; nice vehicle,love the wheels

My engine have 200000+miles. so i'll do head gasket and 'll try to get ARP bolts as well.

in one of forums samebody told me that i should weld the coolant channels in the head to match the block for more gasket sealing area.

I'm not shore that i understand what you told me there''if you have Q's, PM me your number"

Hi. My name in ingus. I’m new in this forum.I’m mechanic my self and loved cars all my life. The reason why I’m wrighting in this forum is that I need some help from BMW enthusiasts! Cause I’m on middle to boost my 1990 325i m-tech project car.

And now I’ll tell short story about my project

6 month ago After full respray and interior job:

Suspension and brakes wasn’t too god so we decided for brand new (I got them almost for nothing )

A nightmare for 3 days.

We had to respray inside cause there was some rust and scratches.

My friend spend lot of time to do wires

I replaced all gaskets and oil seals(I didn’t do head gasket) New ignition,w p and t-belt kit.

This was tricky cause of fresh paint everywhere

Pirate lol

After 6days and lots of red bull

I was so happy that local tuner magazine put it in to next issue!

So now after I drove car and felt that engine power was too week for my new brakes and suspension . (oh and I smashed sump over bump last week ) . I desided to boost it cause it is cheapest power for the money.

There is my exhaust manifold I got it from e-bay yesterday . Looks prity good job. Turbo charger what I’ll use is T3/TO4E A/R-50. I’ve to weld pipe from manifold to external 38mm wastegate.

Plan is to get front mount IC, bigger radiator, electric fan, bigger fuel pump, injectors etc.

I really want to use Megasquirt cause it is DIY. Or there is some better and not very expensive options for ECU? Is there any one who have some experience with similar setup?

How much boost will take stock bottom end? Or it is safer to lower the compression (with thicker MLS gasket and arp bolts)? Where I can found metal head gasket if there is some on market?

How about engine heads do they give trouble?

I this is my first boosted BMW so I’ll appreciate for any help.

Thanks
