T25 Manifold options

[Mark One]

Hi, I'm new

I've been trying to find suitable manifolds for my project with my AGU 20vT

I don't have a lot of room so I need a manifold that has a down-turned T25 flange, So far all I can find "off the shelf" is these two

Both from the US
The PAG parts Manifold £410 delivered to uk
APRs really nicely made manifold sold as part of their $5k upgrade kit

Can't get a quote on the APR, they won't email me back

Anyone Know if the APR is available separately? how much approx
Anyone had any experience with PAG parts or their manifold ? £410 is a lot for a cast manifold (poor exchange sad.gif)
Any other options? Have JBS finished their T25 design yet?

i dont know but if you find out i'd very much like to know... AUQ lump here though and i'm not paying APR 5k for something i can do at half the cost easilly. Manifod is the only problem in my plan really.

I have T25 but its top mounted.
going onto an a3 quattro currently.
tubular stainless. more room on to mount than bottom mount

 

[vee_dub_modder]

what manifold etc are you using?? custom or is there an off the shelf option?? i'm not too fussed if its top or bottom mounted. so long as i have a manifold i can get the rest made up to suit... i think the backdraught kit is top mounted come to mention it??

might get meth injection to keep me busy in the mean time

 

[Mark One]

Right, well I just wrote up a big guide with all the off the shelf T25 manifolds i've found for the 20v. But I can't post it because SCN won't allow me to post URLs and tbh it's useless without the pics.
What a farking ridiculous rule.
I now have to make 15 pointless posts before i can post this usefull guide?!
if anyone wants a copy reply below with an email. I've found 6 manifolds all with prices. Can't beleive SCN doesent have personal messages?

Its bespoke to me and my design.. available in T3 internal gated, T3 external 44mm tial gated or T25 internally gated.

Its designed to fit righ hand drive cars without compromising fitment, and downpipe sweep.

Tubular stainless construction.

I'll snap some pix tonight of the T25 version we're building onto an A3 Quattro currently.

The position of the turbo on ours is ofset to cyl #3,#4 to allow clearance for full 3" downpipes. Most other manifolds are centre exit and sit between #2,#3 cylinder making downpipe and proximity to servo very very close (read very hot things next to flammable things(brake fluid))

T3 version externally gated is here as a guide

and also available in ceramic coating also (my own ibiza racecar setup)

all good fun

Would you consider building another T25 internal wastegate version for someone......ie me?
I'm in the market for a manifold. Just wondering what something like that would set me back.

 

[Mark One]

I've sent round a few emails to get an idea of what manifolds were on offer.

Note that the PAG and the APR cast manifold both mount the turbo over toward the cambelt end of the engine. I'm told these are designed for LHD cars and position the turbo into the brake servo on RHD cars

Firstly, the APR cast manifold. I won't deny it looks like good kit, but it's $1500. Purchase through awesomeGTI. Awesome GTI also offered me a "We can get a twin wall tubular manifold" for £795+vat

---------------------------------------------------------------------------------------------

Next is the PAG parts manifold. $495 + $75 shipping I was quoted.

--------------------------------------------------------------------------------------------

I then sent a quick email to backdraft motorsport in MK asking what manifold they used for their MK4 28RS conversion. They quoted me £500+VAT for their cast manifold

---------------------------------------------------------------------------------------------

I then got in contact with JBS. Very helpful people.
They are currently developing and testing this new cast manifold of theirs. NO ETA available as yet and NO estimated RRP

(note thats a rapid prototype, not a coating)

However, JBS do currently make and sell these beauties for £517.50 inc vat
IHI flange pictured - T25 available at no extra cost

-------------------------------------------------------------------------------------------------

Finally, I found the APR tubular manifold. I think this must be the manifold that awesomeGTI were talking about for 795+vat. Not sure on that at all though.
It seems to have a boss for an EGT too.

Think I'll go for the JBS tubular, or perhaps the cast if it's ready soon.

Hope that helps

wow, custom manifold is looking good! some of these manifolds seem to be mission the point... the backdraught one and badger 5 seem to be the best looking + better designed... ideally you need equal length headder pipes where possible to aid gas flow etc. longer headders produce more low down power, short produce the power higher up the rev band and.... blah blah blah. (sorry i did a 52 page assignment on exhaust manifold design few years back in uni)

basicly some of those manifolds look to be no more than crap, of all those above i'd pay good money for the backdraught option or Badges (if it becomes available fingers crossed)

thats my oppinion anywho guys

 

[Mark One]

interested in selling on one of your T25 manifolds bill?

How would you feel if you logged in and had to wade through 150+posts of crap/spam selling cheap trainers/viagra and nigerian real estate offers ?

The minimum limitations are imposed mainly for that reason and have you have now found it doesn't take long (24hours) for anyone genuinely using the membership

The Private Messaging service activates when you become a full member so you should have availability to it now, if you have any problems just shout

nice list btw

^Cheers^

Just for completeness of the thread.

Found this by TIGART for 1200euros
...not something i can afford!

Pretty much most of the bottom mount cast manifolds out there are no good for RHD vehicles.The top mount manifold from MFT (what backdraft sells) is a good manifold to start with.

apart from what it does for downpipe clearance and fitments - melting things by servo etc when not properly heatshielded. Its still centre fixed.

have you tried bogg bros? i hear they have done amazing things for people with turbo manis a no room. there's another one too... er... PPC had their saab mani modified by them... can't remember, but it might be a good road to go down

ibizacupra; that's one of the most beautiful things i've seen... you fab that yourself?

 

[Mark One]

I wasn't aware bog bros did exhaust manis? I know they are famous for their work getting bike throttle bodies to fit to anything, but didn't realise they did exhaust too.
Might have to give them a shot.

 

[JBS Sales]

We have both stage 1 under-slung and top mount equal length manifolds availiable with a T2 flange on sale now!

Check them out there:

http://www.seatcupra.net/forums/showthread.php?p=2371240#post2371240

The manifolds are designed and developed by ourselves, for ease of fitment and maximum flow.
Both manifolds give lots of clearance in the engine bay and are designed specifically for RHD cars.

Both are availiable as part of our Garrett gt28 turbo kits or seperately.

JBS Developments

downpipe fab'd by me, manifold no.. commissioned by me

 

[Mark300zx]

On turbo cars the advantages of a cast manifold are, more compact, lower cost and only a slight loss in the top end, they are not perfect for maximal BHP, but for a low cost increase in power with less chance of cracking, cast iron manifolds offer a viable alternative!

 

[PhilW]

Bill, whats the cost of the downpipe, ibiza flavour and garret flanged, non v-band?
