Up and running
YouTube- Alfa Romeo 155 Q4
The design of the IC is not on the most efficient side either. The most cooling happens in the first 20cm of the IC, so as thicker and higher is the IC , the more the air is cooled.
This is a very...
I will upload it somewhere when i get it on the computer:)
I think it wont be such a problem to share it :)
If you gor for 300bhp you won't need those 12mm bolts and bigger injectors. If you go for the bigger injectors the fuel map will need to be fully adjusted(which is a lot of work :) ).
I can get...
With stock pistons and conrods you can see 300bhp with no problem BUT i would definitly fit a spesso head gasket,very good oil(motul v300) and wrap the manifold or ceramic coat it, so you keep the...
Alfa 155 virus...he doesnt like the others :).
Here are a few piccies of the work done on the Q4 by the new owner(he is actually my friend:) and lives near).
A pics with his 155 1.8ts when i delivered the car:...
Yes :).It can be tuned to around 450hp with changing the head gasket,clutch,injectors,fuel pump and turbo with stock internals.I will be more modest...my goal is 300.
I know that bugs are everywhere :D but i tryed the car and it suits me very much, its built quailty is way better then the Q4, the engine is easily tuned to 400bhp without changing...
No special reason actually...i needed a car and i grew tired of the constant bugs and problems with the Q4 so i made this decision.And also i fell in love with another 4x4 turbo car....an Audi S4(C4)...
Yes:).I drive a Saab 9000 2.3 turbo with around 250hp:).
Something like this only in black:

Hi!

I'm using the Siemes Deka 630cc.They are plug&play except for the fuel table.
IF you want to fine tune it you will also probably need a WideBand lambda and a controller with that.
The car is almost ready there are still a few problems left(some electric problems and a few "beauty" issues and so ) but that roughly it:)
Here is on the truck becouse is still had the old chip...
This header will be completly wrapped in 1600 degree celsius Heat wrap and also the turbo will have a heat shield so there is not much worry :).

Very nice job but i have a few question :)
I guess with the stock internals you wont be pushing more then 300-320 hp ??The pistons are good for around 330bhp ONLY if you intend to overfuel it a...
Yes the more i looked into water injection system the more i found that the benefits are quite significat.So i am going to try to install one in the Q4.For starters i will buy one with a pressure...
Hi guys!

This system are not that expensive but the benefits are quite good(lower EGT's,less chances for...
