Hello zoners .

I need some info on a A great find here ,
See i went to a Mitsubishi used parts shop , and the owner had a few e30 bits came with in the container .

Any ways , Not Much to mention , but i found two great pieces .
one of them is a Racing dynamics headers .

Well , My Engine is an M20B27 bottom end with b25 top .

Are these headers good for my setup ,
also What about gain , or maybe i guess it'll just breathe better because of the Outlet and stuff ?
And he asked 120 quid for it , Should i take it ?

Also He Has a Hartge Valve Cover , But he Asked for 80 quid for it , not actually sure about the valve cover , but i'll think about it .

Now I need to know , are these headers good ......

Also Another Question .

See The Cylinder head has 12 headers stud bolts ,
The Stud hole #12 On the 6th outlet is bad , and the teeth can't be combed again , can it be fixed , if did weld it and re-combed new teeth ..... ? or can i just stick the manifold on like the OE one,
The OE one on my car is standing on 11 bolts and it's cool and no leaks , but will these headers leaks , I don't Think there is that much pressure to make it leak as-well .

Cheers .

A Hartge valve cover can go for about 250 quid in the UK ...

Buy the headers and valve cover and move them on - you should be able triple your purchase price - if they are genuine of course

If your on a stock cast manifold then a set of headers will free up a few ponies from a 2.7

if the manifold is a gen RD one then you can easily make three times what you paid for it as genuine ones are very sort after.

the hartge rocker cover can go for £250+ as cloggy saint says.

if it was me though i'd buy them both & fit them to my car winkeye
if it's got t*ts or wheels it's bound to be trouble...............prove me wrong.

The RD manifold is about the best there is for an M20, its a work of art. they also sound epic, they're designed to work with a 280 ish degree camshaft for the most benefit
