hey, i just noticed this manifold on ebay, and im wondering if it would be any better for me to have this to replace the standard magna manifold? would i get better performance gains and whats the difference between the 2 besides the look?

My car is turbo BTW so im talking better gains with having the turbo setup?

thats just a 1st gen plenum and intake manifold :nuts:

r u sure?? the plenum inside area looks heaps bigger. which is one of the weak points on 2nd gen 2.6l. also vip it is older technology, and the water ports are different shapes on some of the different heads

is it better than having the 2nd gen setup? i dont care were it comes from.
Are they not the same as the starions, heres en example of a starion intake with nos, currently on ebay. the only diff is that the T/B sits in the other side.

hey magnatism, werent you after nos? thats on ebay, all you will need after is the nos bottle.

**** me thats direct port too how much

$800 buy it now, it located in australia goldcoast so no over seas postage.

ah screw that $800 is too much i can get direct port kit with bottle for $1050 and have it fit my manifold with no mods. i was hoping for like $200 or something and i would just strip the nos off it

no, well theres bairly any difference at all between the 1st and 2nd gen, the 2nd gen has a bigger throttle body how ever and a bigger plenum to match, also if your going to use the injectors from that one off ebay note that they dont flow as much at the blue tops also i heard the fuel rail in the 2nd gen holds slightly more pressure

the reason why people put them on up on ebay is because there a hot item in the US, but you will notice with that pic that someone has welded the throttle plate on the other side, you need to do this as there motors are rwd set up, you need to do the same if you want to efi sigmas or any rwd astron

i just feel as though the manifold is slowing me down, i heard it was because of the longer intake runners the 2nd gen magna has, if you look at most turbo cars they do not have really long intake runners.

i have 600cc injectors for my car, i defenantly wont be using others, and as for the T/B i have an XF on to go on the end, im just wondering about the different intake setups before i go mod the magna 2nd gen one.

that is exactly right too mate the runners are very long and ur plenum volume is small most turbos have short runners and a big plenum. if ur gonna get a manifold made i will get one too coz i want a bigger plenum... maybe we could get discount for 2???

you will definitely benefit from the t/b upgrade but u need to grind out ur plenum entry to get the extra air thru. but it is too small the rest of the way down anyway

im goin to get the starion one and mod it by removing that plenum and getting my bro to make one up, he does welding of some sort, and ill get it to fit the XF T/B

i will ask mick at ovaboost 2morrow wen i see him. he makes his own but probably isnt keen on making them for customers. i'll ask tho. try rpw the guy they use for welding manifolds and stuff i think has his own business street torque fabrication or something and is inm perth street car mag.... anyway he is very good and knows his stuff

hey if ur bro is up for it i want to try making a new plenum too for the xf. i already have 2 x12mm aluminium jet cut plates to bolt to the intake manifold itself as the basis for the new plenum. i will sell u one if you want or give it to ya if ya can help me actually make one too. i got a heap of stuff cut in the hope of makin twin t/b...

yeah mick is really good at what he does, i will be getting him to tune my car, when im ready for it, what sort of metal is the plenum made out of ?

cast aluminium and its good quality too it can be welded to very easily... also if ya want mick to tune ur car ring now and leave a msg coz he is really really overbooked. also he hates turbo magnas so it might take some convincing he told me he wont work on them but agreed he tells it like it is and doesnt tell u what you want to hear

ive already talked to him about it, awhile bak, he worked on mongas magna, and we had abit of a chat when that car was in there, they did the custom 3' exhaust system and intercooler piping with FMIC, wich i have on my car now.

i actually asked if he had tuned urs but he said no... so r u just runnin mongas tune??

yeah, so it hasnt recognised my mods yet like the cam for instance

Ok i talked to my bro about it, all i gotta do is wait for the starion manifold runners, ill cut off the chamber and get my bro to weld one up and fit it to the runners of the starion. did you say you had the XF T/B flange ?

no not that flange check my post bout it on page 2 i think, the pic is of the plenum base. just cut the t/b flange off ur magna plenum and use that. u need to enlarge the mounting holes slightly on the xf t/b to bolt it together

so was monga using a turbo cam?? or standard??

evrything on the car was standard. with a turbo bolted onto it, my mods start from the boot with the fuel pump located in my boot, then to the engine with an adjustable fuel pressure regulaton, then the stage 2 turbo cam, with stage 2 port and polish, double valve springs with custom retainer, compression has been lowered, currently using smaller injectors, but i have bigger ones to put in, i just dont know how to set up the wolf ecu run these injectors, also i have the bigger turbo aswell but i require a custom manifold for this turbo, and once the engine comes out agen the pistons and rods will go in.

hmmm **** maybe there is some power to be made

Those multipoint systems you are seeing on ebay would have come from magna 2.6's originally (so what you already have).

Starions/Conquests (and cordias) never cam with multipoint fuel injection as standard. They came with a twin injector setup, some people like to call it an glorified electronic carbie.

And like someone already said in an earlier post these are hot item in USA because they never had multipoint 2.6's over there so people here in australia sell them to the americans and they get converted to suit rwd (hence the reversing of the blocked end of the intake).

Obviously its also an upgrade option for the starions here in oz but its a bit more work since they come with a 2l standard not the 2.6.

yeah im not goin to bother with that intake, i did abit of researching and found that shortening the intake runners creates tourqe in the higher rpm range, and this is were the 2.6L engine struggles to make power, maybe it could have been the intake manifold restricting the other turbo cars,if you notice most 4x4 motors the intake runners are long to provide low end tourqe for towing. in most turbo aplications the runners are relativley short, ill post some pics up of how it will be done. including a larger XF T/B.

If you were gonna have custom runners/plenum chamber made up have you thought about maybe getting a bigger plenum chamber made up and using long runners for low rpm, say <3000 and then a butterfly setup with shorter runners that opens up at revs > 3000.

The V6's run a setup like this, they use a servo to control it, but you could probably also use a solenoid that operates from an output from the ECU.

And here's a good site on how to do basic flow calcs and how/why the runners and plenum are designed the way they are. It's more for N/A engines, but it explains the basic theories really well. http://www.team-integra.net/sections/articles/showArticle.asp?ArticleID=466

ive already been through that article, pretty interesting ey, thanx 4 the link neways.
with what you described, im pretty shure the fords had that, its not really a concern when it comes to turbo application, just getting the air in there because its all pressurised.

No other turbo magna has tried this mod, and by looking at other engines of the starion turbo, the plenum has shorter runners, even if it dosent make a difference, atleast it will dress up the engine bay bit more.

Yeah a new plenum/runners would make a massive difference, especially on your car with the mods and a tune.

Although I'm not sold that the ram effect is a non issue on turbo engines. Sure, the intake is pressurised, but you will still get a pressure wave as in a N/A application, the difference is that the wave speed will be different. That's just my opinion anyhow.
