Forums Forums Enthusiast Forums A - Z Autowirral mantzel inlet manifold

has any of the vauxhall boys or anybody else ever fitted a mantzel inlet manifold, tony had offered to help out but was just wondering if anybody has fitted one before, need to no asap, before i buy it

Lets see some pics mate

this is hopefuly the one iam buying,


and this is one fitted and painted

Do you know if the ports match?
If they physiclly fit in the bay?
If the bolt hole align up?
If TB (Throttlebody) will fit?

Answer these and I can help

Right you havnt replied and am off out in a min, by the looks of that pic (and I found it on eBay) it will go on.

It comes with the throttlebody etc the only things extra you may need are a gasket and a induction pipe to connect your filter. Fitting wont be hard either

iam not sure on the answers to those questions but iam trying to find the asnwers out, the induction, i believe you use a cav diesiel or something but iam finding that out aswell

You could buy a length of silicon hose if you got stuck as there doesnt seem to be any sensors in it, its just a piece of piping

just found this on mig web, i wouldnt have to change the lower inlet,

remove upper inlet manifold and throttle body, remove lower inlet manifold, swap fuel rail onto new lower manifold, extend loom for the tps on the throttle body, fit new lower manifold, bolt throttle body to the mantzelbox, and mantzel box to the lower manifold, recconect throttle body, fit new servo hose and vac pipes, job done

That says you do.

I posume by lower manifold there talking about a sandwich plate?

Seems pretty straight forward aslong as you have all the parts - Just need to extend the wiring

yeah, i no it says there but ive allready got the correct lower inlet manifold

As far as i know its a direct swap

thought u wud be after an xe after u had ago in mine

His power will be close to an XE if the mantzel pays off 15bhp increase. if he then get a manifold and cams. even pullies he could be on for 140bhp

Lawton! what u doin to that pimpin corsa now?? whats next NOS? a turbo? a jet engine?

lol, decided not to but it, as to get the best gains from it then i would of had to buy a manifold, cams and a re-map, would rather spend the money on bodywork at the moment
