Crazycage,

top work

Any pic's of the mani before and after your mod's. and before it got wrapped and fitted?

turboben

and any pics in the bay to see how the turbo sits top work dude

smitsturbo

i think i might give this a go myselfor pay somebody else anyway thanx for the insperation

Gotta take my hat off to u mate that some good work.

What one do u mean by: -

use a 3 bolt cossie one then,that would b better

Cheers,

Jim

Ł1100 for a manifold

"Hello Norwich Union can you quote me happy on my exhaust manifold please"

JamesS2RS

Arr i see so u have to cut and shut the down pipe as wel?

Jim

Rick

So, if you have a cossie 3 bolt housing, is this a straight swap? Is the flange for the housing not different on the 200sx? What about the downpipe - does this line up in the same place, or is the turbo further forward/back.

Rick.

turboben

from what i understand you will have too make a custom downpipe to bolt up too the 3 bolt cosworth turbo unit

I didnt mean that as a bad thing.. by using the ' '

Just he didnt want the Jamsport manifold, Which is yours... Obviously he didnt know




PS:

Are you making the 'over the gearbox' manifolds now for Jamsport too? Think Stuart has one? Or was that a one off?

Or just the normal one, As seen on MK's, Tom Scarlett's etc...

Fiecos Dan

200 sx's use a T25 flange.

So will need to be changed for a T3 flange.

Rick

Yes i know, but a lot of people already have a custom downpipe...

smitsturbo

would the 200sx manifold pipes line up with the cvh head where the headers need welding on to them or does the tubes need moved/extended etc? good thread this

JamesS2RS

It’s a wicked idea but not as simple as first thought.

But if you could make them for 150-200 pounds then I think it would be well worth the effort.

The concept is easy I just think there will be a lot of try and error with getting the down pipe adapted to fit on to cosworth housing.

This is my conclusion of making one: -

Make a flange to the same size of a CVH head (copy a gasket)

Cut the old head flange off the 200sx

Weld the pipes to the new flange

Fit a Cosworth 3 bolt exhaust housing to the t34/t3

Then adapted the down pipe.

We need to confirm what turbo flange the 200sx has either a T25 or a T3
And how easy it is to change the standard down pipe.

Crazy cage please correct me where im wrong because I think you could be on to something here.

500 / 1100 quid is stupid money I no p/d work is second to none but on an RST it’s a joke.

heres some better pics of the manifold on ebay

JamesS2RS

Good work lee looks like a T3 flange to me

they are creap for a reason look at the weldin on the inside of the manifold on the 2nd link and compare it to



u get wat u pay for

Charlie Chalk

iTrader: (1)

I must admit, I'd have to have either a custom one made or Brians one

Even if it ment having to pay out Ł600+



I hate to think what the cost of my Manifolds are gonna be on my S2

JamesS2RS

Stuart which one are you using?

And how much was it?

what did you do with your down pipe?

Cheers,

Jim

stuart collins

iTrader: (7)

mine but with external waste gate pipe underneath



u can get the down pipes from jamsport in 2.5 inch or in 3inch

2.5inch down pipe on the left, just needs weldin or clamping to the original exhaust

JamesS2RS

Cheers stuart

The quality looks mega.

Cheers,

Jim

Hansenturbo

No problem m8 yes you can get the manifolds over the gearbox too and the 2 types of manifolds also comes with zetec flanges on if you got a zetec

smitsturbo

Hansenturbo have you any pics of the manifolds that go over the gear box mate (on & off the car) & are they the same price

stuart collins

iTrader: (7)

theses ones are Ł850

Rick

the sx manifolds christian gets are much better than the ebay links, with nice welding.

crazycage thats some great work you have done there. and a good price your asking too got any exterior pics of your rst?

Fiecos Dan

200 sx's are T25 exhaust housing.

crazycage

2 put things rite the sx manifolld has a t28 flange ,but all you do is weld a t3 one over the top of it and the pipes dont line up so all i did was heat them up and make them line up then weld the new flange on ,you need 90 degre bend for the down pipe or get one made

Fiecos Dan

The turbo fitted to a 200sx is a t28,

but it uses a T25 exhaust housing and shaft, and a T3 comp side.

crazycage

mybe but an escor t3 or cossie t35 will not bolt on 2 a 200sx manifol

Fiecos Dan

Yes i know, thats why i wrote this earlier.

turboben

call me stupid but why not just use a t28 turbo with the manifold then all you have too do is make a flange too fit the cvh head just seems a bit easier
http://cgi.ebay.com/ebaymotors/ws/eB..._promot_widget

works out too about 500quid for manifold and a brand new ball bearing turbo

Rick

because the point of manifold is big power, more than the t28 will give.

crazycage

[quote="Fiecos Dan"][quote="crazycage"][quote="Fiecos Dan"]The turbo fitted to a 200sx is a t28,hope this helps ,

JamboRS

the manifold does not give a huge increase in power,its how the power is delivered and the pick up that benefits,power is not in the thinkin when makin these,the extra power you may gain is prob of increased boost after fittin and mapping session/rr set up

crazycage

at the same boost you should see 30ftlb an some bhp but all depends on engine spec you will get much better responce on an off boost

So do you all think a tubular manifold will reduce lag? because if you do you may be quite supprised.
Tim

crazycage

so wots you vue on them then? gary

Tim

iTrader: (1)

lets put it this way take a cossie engine with a 2 wd manifold which in reality is a cast tubular design,then take the same engine with a 4x4 manifold which is just a cast design manifold,the 4x4 1 is loads better and has less lag than the other unless you want 500 plus bhp when yes a tubular 1 of correct design will be better but will cause lots more lag.
I would like to see a fast car with a tubular manifold that works correctly the only 1 i have seen so far is nicks car from PF. and IMO the cost is way to high for the benifits.

I tend to agree with Tim. I cannot see why people think that making the exhaust side less restrictive will result in more torque??
