Hi
Has anyone fitted a manifold to there st150 and got any fitting tips, im fitting my new 4-2-1 mongoose manifold tomorow but as iv never done one before so just wondered if its easy or hard to do.

Thanks in advance
Benji

Hi benji,

The ST engine bay is fiddly to sya the least...Ive not done a manifold change in one yet but have done several with other cars, we always found draining to cooling system and whipping the radiator out helped no end, also, make sure you coat the bolts in WD40 this evening in time for tomorrow

You dont need to drain the radiator on the st as the exhaust manifold is at the back of the engine,
Fitting Tip-
1. Remove the original flexi.
2. Remove the lower gearbox stabilizer.
3. Remove the original manifold.
4. Support the engine front underneath (Beware the sump is fragile).
5. Remove the cam chain side engine mount and PS tank lid.
6. Pull the engine forward and down.
7. Expand the transmission tunnel heat shielding to allow for the 4 new headers.
8. Slide the manifold in from the top and bolt into place
9. Re-assemble the vehicle.

Thanks thats a big help,
Iv already got a miltek flexi pipe do you think i will see a diffrences going to the manifold?

Hey

Does a flexi pipe make a difference as was thinking of getting that.

Thanks

Flexi Pipe in my experience improved drivability at low rpm. Makes pulling off much easier too as i found the ST quite difficult to pull off smoothly. There maybe gains top end - but personally i havent found any.
