hi all just bought a set of syms headers from polepostion second hand.

fitted them and fitted new clutch and then:

started the car and it sounded like a rally car that rough.

took it out for a 2 mile drive taking it steady, got in and the manifold is glowing red near the up pipe join,

and its course the car to boil.

any suggestions?

Do i need a remap, is it posible its blocked, or failing that, the turbo has a crack in the exhaust housing has that got some thing to do with it?

cheers

Hi there
headers has been heat wrapped?If no i would suggest try headers heatwrap with DEI or similar heatwrap.
But i would also suggest get headers mapped as well,but this will not cause your problems.
You have fitted EGT gauge?

Hi mate, i have syms headers on my scoob too and they make the car sound savage , are yours the type that has the twin up pipe that joins into one just before the turbo flange? I also hope you have heat wrapped them? Have you got all the right sensors in the right places?
Syms run very hot and i mean hot, this is because they are designed with small 38mm stainless tubing which increases the velocity of the exhaust gases and in turn spins up the turbo alot quicker but the downside to this is it generates alot of heat (glowing exhaust). I heat wrapped mine with dei titanium heat wrap and they and the car are fine. A remap is a must if you want to run them safely do not run them on a std ecu map, this is because the headers make the engine run totally different so it will be running lean at certain points which would explain why your engine is getting hot its just a recipe for disaster without getting the car mapped to them.

wats a EGT? they are wrapped but i dont think its a very good wrap. may have to get some dei stuff.

but saying that they were on a high spec type R before, like 400bhp jobbie.

Get the map checked.

makes sence, ye is is the 2-1 setup. ye all the sensors are back in place. and the exhaust is wrapped but not using a very good wrap as said above it was on a 400bhp type r i think.

my car is already mapped by bob with a vf30turbo, 255, fmic, and a kn to 341bhp so i dont think it should need a map that badly.


really stumpt on this

Was it mapped on those headers? If not, it WILL need a tweak.

To quote Harvey Smith: "You play, you no pay, you pay for new engine."

When I had my (Harveys) special up-pipe installed both Harvey & Zak at Mocom suggested running off boost until I got the map tweaked.

+1 that quote could'nt be more correct even if you tried . Joe seriously mate you need the map sorting out, if you run with these headers without a map adjustment to suit the new set up then you will almost certainly kill your engine trust me i already have the t-shirt for doing it dont go down the same road its expensive!

Egt. Exhaust gas temp

well i will be going back to Bob to get a remap as soon as iv wrapped them in some better, DEI wrap and got a new turbo, now looking at a vf43 as the sc38 turbo one is the one to have, but i think to run that i need a forged engine.

and the vf43 can run a happy 360bhp without stressing the engine to much.

as for the exhaust gas temp gauge im going to look into one now.
