cosworth intake manifold
has anyone got one of these fitted on their scoob? is it a good mod to have? i know the bhp response isnt massive but i take it it would be a stronger part than the stock manifold.
if anyone has a pic of it on their car could they post it please? :thumb: |

sweet, is it a direct bolt-on or is there any mods to make it fit?

its a long long way from being a direct fit, realy out of most peoples scope, |
f me chibisf now thats an engine bay ! whats that kicking out bhp wise
|
that is a pretty special bay!! :)
|
I wouldn't bother with a cosworth manifold unless your going for 600bhp'ish and above. I have had an aftermarket manifold on mine for years but I have never known if it has made any difference?
|
We fitted one to Scott's car, it made 630 bhp from a GT35/42R on a 2.1
We made a mounting block to fit a cable throttle body. It certainly looks the part, only back to back would prove anything of course. |
we got a stock newage manifold on an everyday street car that still has aircon and uses straight v power from the pump and it made 604 bhp, so when do these realy become nessasary
|
It looks to me like these keep the tumbler (or tumbler delete) blocks, would you not be better off with a 1-piece Spec - C manifold?

Its been back to back tested in the states and is doing nothing for cars below 600bhp... thereafter its providing some decent gains.
So basically proves that the stock manifold doesnt become a restriction till after those flow rates. |

I don't care if they help or not, I want one because they look good :norty:!
Attachment 53908 PS. Not my car :(. |
would a spec c Manifold offer a performance again over a sti spec ? or are they used just to give a clean bay ?

Only if the sti manifold has TGVs fitted. Of which i dont think they do. The spec c manifold does help creating a little more room when using a larger turbo inlet pipe however.
I thought all UK STI's had the tumblers - Jap Performance parts has Spec-C's in for £100 - this is without fuel rails and the fuel rail mounting points are different to the std tumbler positions, I had to make up brackets for my Perrin Rails (will be making up nicer CNC ones at some point). Plus a bit of vacum hose re-routing is needed! |
Certainly the sti 7 and 8 uk cars had the tumbler bodies, but no internals. ( as far as i know)

The engine bay is dominated by the manifold on Scoobies, and let's face it, only its Mother could love its looks. The Cosworth one opens a whole new world of expression with paint schemes, as you can see from the two pictured so far. The cost? who cares? |
just because something isn't necessary, doesn't mean that it will not provide benefit or improvement.
|
For what it is worth, the restrictions on these engines are on the exhaust side and not the inlet side.
Spend a lot of money on a Cosworth inlet manifold if that is what you want to do but it is not the most cost effective expenditure if you want to up your power. |
And the most cost effective expenditure being ?

I'd say a £1 for Autotrader so you can sell the damn thing before it bleeds you dry! other than that, just smile and hand the money over.:thumb: |

Look lovely but too bloody expensive for me to want to try one. I think the std manifold is working fine for me.
|
With you full spec Dan it might be possible to suggest cost effective mods for you.

Anybody running the Tomei quad throttle system? Price drop at the moment for the bargain of $4990, perhaps we should organise a group buy?
