My E30 325i turbo project
Hi. My name in ingus. I知 new in this forum.I知 mechanic my self and loved cars all my life. The reason why I知 wrighting in this forum is that I need some help from BMW enthusiasts! Cause I知 on middle to boost my 1990 325i m-tech project car.
And now I値l tell short story about my project
6 month ago After full respray and interior job:
Suspension and brakes wasn稚 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稚 do head gasket) New ignition,w p and t-belt kit.
This was tricky cause of fresh paint everywhere
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値l use is T3/TO4E A/R-50. I致e 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値l appreciate for any help.
That looks awesome, man. Good Job!
What ever you do make sure your effective compression ratio stays at or below 12.5:1 and run 91 octane or nothing will keep the thing together. There are kits to do what your attempting out there complete with bar and plate inter coolers and plumbing. Get a turbo timer, follow the directions and be prepared to spend some bucks on tuning to get it right and reliable. Cheapest thing you can actually do is a dry NOS system with the nessecary upgrades. It only works when you need it and doesn't hog premium gas like its going out of style.
