keep us informed ...!!!

My current header setup is 4-2-1(38mm-42mm-48mm) and the lenght of "4s" is 38mm and the same are the "2s".

I think it would be better with the same pipe diameters but a bit longer "4s" in order to have more top end power.

I will have a new custom header with better curves and better quality.

The thunder header that is 4-1 with 55mm pipe i think is too big even for the 1.5

Ofcourse I may be mistaken.

I THINK SO TOO...

mi exhaust that is of 50.8mm...

waht diameter would use for the new header?

The best thing is someone to test 3-4 header setups to the same car and then we will have an idea of what works good on a stock mzr.

When an engine is tuned, then the header must change too.

There is a lot of theory of how the dimensions of a header must be,according to the engine specs,camshafts,power band,rpm limit etc.

I'm dont know this theory but I've tried many different setups on my car and i think that for a stock or lightly tuned mzr 1.5 or 1.3 a good setup is a 4-2-1 header with 48mm pipe and 200cpi cat.The catalyst must be not too close to the header.

This is a 0-170 video with not the ideal shifting because the camera was in front of the revmeter!!

The road is slightly uphill.

I just finished installing a prosport Oil Temp gauge.

hey vds, what's the other electronic gizmo near gear lever? I'm very curios.

and regarding oil temp meter: was it difficult to fit it? have you had to drill somehow the block?

The sensor of the gauge is depicted in the last picture and it is attached to the bolt of the oil pan.Everything was done by me and it wasnt very difficult.

The other thing is the MSD DashHawk.Google it.

i have a authometer phantom ol presure gauge.. but I have not installed...

the msd dashhawk, from which it takes the signal?

ecu? interesting gadget

i need a install a wather temperature gauge...

I think you should have got an oil filter spacer which is actually the adapter for the 2 sensors, oil temp and pressure. The reading should be much more accurate using this method.
