What Manifold.....ct9 turbo

[madmax_926]

im looking to replace my manifold i dont want a zisco, as i have had problems in the past as well as couple guys local to me.

ideally i wanted an equal length manifold but have been looking at:

speedvision:

http://speedvisioncps.com/index.php?main_p...;products_id=57

wepr:

http://www.wepracing.com/engine/turbo-a-ma...nifold-upgraded

are the above manifolds any good has anyone had problems with the manifolds failing or the service the 2 companys offer is the wepr noticeably better than speedvision

or are there anyother companys?

Wepr seem more reliable IMO

Just aslong as your decats braced

[madmax_926]

are these safe to run 1.2 bar?

[mattyD]

a ct9 would struggle at 1.2 bar, go for a stainless mani if you can! y not a ram style mani if your looking for more of an equal length sorta thing?

[madmax_926]

zisco and me have agreed not to trade with each other althogh if someone has one thats in full working order i would buy 2nd hand its a hybrid ct9 anyway mate

WEPR products are great, and Sacha's service is superb.

i would disagree and say go mild steel, the likes of wepr

failing that I would port a standard mani before using stainless again..

[madmax_926]

right bought and paid for a wepr now thanks

mild steel is overrated lol! plus i would never choose a ported mani over a stianless steel one, its all down to how its been made, what the welds are like and what grade of s/s they use

ive had 2 different s/s mani's and both cracked, ported 2 OEM mani's and never had any bother. I also had leaks on both s/s mani's from the head to manifold and never any leaks from the ported OEM. I also know people that were running 1bar+ on td04 on ported OEM mani's with adapter plates with no issues.

Saying that, he has already bought a WEPR mani

cheers guys lol

the unlucky ones in the batch what makes were your s/s mani's if you dont mind me asking?

good on the lad, wepr makes quality stuff so shouldnt have many problems

I agree with getting a mild steel one, all the ss ones tend to crack.

Stainless looks nice but is brittle, doesn't like going from hot to cold all the time! Had to have mine welded after less than 1000 miles

Good choice on the Wepr mate

[mattyD]

my mild steel one cracked! so im gna try s/s for a change

loads of people run s/s without any problems, its just down to personal preference i guess
