Which Exhaust Manifold?

[mos 1]

hi,

 

dropped my s16 engine with mattsav at qep yesterday for the 88mm/88mm bore stroke conversion.

the engine will get the usual gasflowed head cams etc as well and i hope in conjunction with the kms throttle bodies and managment should be good for at least 200bhp.

 

the question is which exhaust manifold should i buy

 

spoke to matt about it and we ruled out the s16 manifold (which i already have) as it probably not up to the job and he suggested either a gti6 manifold with the head studs modified to fit the different stud pattern or something like the maniflow one etc ( i think pugspares was also mentioned, pretty sure Miles was mentioned too), again with the cylinder head being altered to accommodate it.

 

not sure which way to go with this to be honest, the gti 6 option is probably the cheapest and i do not want to needlessly waste cash,

but that said, with the shear amount of money this project is already costing me it would be stupid to fit a cheaper inferior option just to save a few hundred quid.

 

p.s if something like the maniflow is the better choice, would i then be better off getting the full system from them and selling my mangnex system rather than trying to alter it to fit the new manifold.

 

thanks

Matt should be able to advise you on what manifold pipe geometry ought to work well with you engine. Maniflow have just made a custom 4-2-1 for a 205 i'm involved with, to the cam designers spec and it's very nicely done i have to say!

"Maniflow have just made a custom 4-2-1 for a 205 i'm involved with, to the cam designers spec"

 

How much did that set you back, and what spec is your engine?

 

Is it worth getting a custom one if your engine isnt a full race setup?

[Miles 331 1 Cars]

The std 16v 4-2-1 manifold does fit the engine as they now have a universal face, But as the 2l engine is higher is won't fit in the car without resting on the bulkhead, So you can either lower the engine abit or get a custom manifold made up,

[mos 1]

not sure what course of action to take

not keen on lowering the engine as this sounds like a major pain

anyone any ideas on a custom manifold

this sounds like it might be a way forward for me

how much was the custom manifold if you dont mind me asking

 

you guys out there running modified 2.0ltr iron block engines, what exhaust manifold are you running

 

maxi's name was mention by matt at qep i think, apparently he got a similar engine to what i am aiming for, anyone know what he has done, i did try pm him but his inbox is either full or disabled

You've got Torque Tequine (Spelling) up in Maccesfield they do a top job and come recomended, They did a system for me years ago.

[Sandy 191]

It was a bit of a 2 way deal, so the price isn't going to apply to everyone, but it was very reasonable, you need to ring them and ask really. The length of the manifold suprised me a bit, the secondaries go well past the gearstick! This car will have an internal gear linkage, so there's alot more space available. I can't give you the precise dimensions because they are the intellectual property of the cam designer.

did you mean tube torque, they are the only company i seem to be able to find any details for who do this sort of work in the macclesfield area.

any idea what sort of money a manifold/full system normally would cost to be custom built. i know you cant really answer that question but i am just looking for a rough ball park figure as its not something i have ever got involved in before

will have to speak with matt at qep to see what is required,

i would have though most places would actually want the car with the engine insitu to develop the manifold on or is this not the case?

Thats the one, 'tube torque' they need the car for sure as anyone making one off the car must be out of there head unless they have the Jig already, Mine was done a good 10yr's ago and that was a system which was around £400.00 from memory

i will give them a call on early next week and see what they say

[petert 587]

You could do what I've done and get Matt to make an angled plate (see this thread, http://forum.205gtidrivers.com/index.php?showtopic=63496). I've made it to suit either the 10 or 9 stud pattern. However, there's a lot more work involved to make it fit a 10 stud head than first meets the eye. I'd suggest that the amount of time Matt would spend making the plate and getting it to fit, would be better invested in a custom set of pipes.

[mos 1]

petert i think you are right,

 

particularly after reading that thread you attached

i just hope it doesnt cost the earth, particularly as if i have a custom manifold fabricated i will also have a full system built otherwise i will be, or at least i feel i will be just cutting a corner to save cost

i will speak to maniflow early next week as well to see what they can offer, likely cost etc.

only problem for me with maniflow is they are the far end of the country from me and it would cost a fortune to transport a non running car there and possibly back a well.

at least tube torque is reasonably close to me, about 30 miles i think as apposed to about 300.

 

anyone else out there had experience of using Maniflow or Tube Torque, how did you find them and their workmanship?

 

thanks

There's a company just outside of Salisbury, Torque Techique (Knew I got the name mixed up) which do the same thing, The man that run's it used to do all the special builds at Maniflow

 

Maniflow made a lightweight stainless system for me 5 years ago at £500.00

i take it that was for a system only, not a system and manifold?

i will try to give him a call as well next week, just got the details off yell.com

only problem with either Maniflow or Torque Technique is they are the best part of 300 miles from here (manchester) if they need the car the it would have to be transported down as a non runner.

i have never done this but i would imagine it would cost an arm and a leg!

Tony Law in Leeds has received good recommendations

[JeffR 51]

Apologies if I've highjacked your thread mos.

 

I'm in the same quandry as what is the best exhaust with my spec engine on an XU9J4/Z 1928cc (83.5x88mm).

 

I've got 11.2:1 CR, 48mm t/b's, B/V head so should I stick with the 8 branch manifold, oem down pipe (2") cat gutted out then go for a 2 1/4" pipe dia with a 12" resonator mid-way to the back box-(a Devil-26" X 6") with a 2" tip, or am I choking up my max potential?

 

I'd hate to power down the engine spec with a mis-matched exhaust.

Hi Mos hope those 2.0 Mi engines are going well in your care .

This is my virgin post on the drivers forum so here goes.

Tube Torque in Macclesfield is owned and run by Mark goslen and he is top drawer in his buisness he has made numerous systems for me and my friends on a varied state of tuned cars from Nova sports, 205's , lancia delta Integrale 's ,Lotus Sunbeams,Manta 400's , Cosworth's, and many Rally cars.

He will need the car with the engine installed but will manufacture to a spec or specific requirement Timed manifolds (QEP engine spec) and fully understands the correct torque and gas flow requirements required ,he has impressed me every time weve used him with knowledge and quality and i personally reccommend his work .

I would expect circa £600 all in.

Ive seen some serious machines there inc full works Metro 6R4's and lancia Stratos's .

You've been exhausted !

Hope this helps Mos ..

Hi Miles,

 

i take it when you said lower the engine a bit you meant exactly that and not to tilt the engine on an extended lower engine mount

its just that i have noticed one of the s16 coversion stories on 205gti.com that a guy got a manifold from a company in the uk called racing solutions, i have never heard of them. this required him to tilt the engine slightly and modify the black bar on the subframe.

 

Anyboby know of racing solutions and contact details for them, may be worth a call.

 

thanks

Hi mate,

 

welcome to the forum

i am trying to get around to phoning tube torque i ask for mark and will mention you when i speak to him

feel reassured about him after your kind words, if i do have one fabricated from scratch he is the logical choice, due to location etc and reccommendations and circa £600 for a manifold and exhaust is pretty good.

the engines are both with QEP they are going to use the damaged/scrap block to establish that 88mm bore is safe before using the good block for the actual engine, i gave him both heads so he can choice which one is best to use.

in fact i gave him everything i had from you except for the coils/loom that you supplied me.

i took the lot down in hire van to near brighton where they are based last week before heading into mid Wales to look at a steel grey 205 that i did not buy as it was a dog and then the van broke down in the middle of no where no phone signal!!! but that really is a long story!!!

[Dazza 4]

Oh those hire vans breaking down in mid wales ha ha ,the joys of motoring eh ....

Nice to see all those parts will get used and i will keep an eye out for a nice steel grey 205 for you .

I bet the 88mm bores are mighty tight in the block as the walls are getting a little friendly as sardines .

Still if it works you'll have a big bag of torque to play with and a few more ge gee's no doubt .

Ive just been out playing in Andy's rally 309 Mi 16v (alloy) and it was very nice to chuck around and flick it side ways nicely to very well balanced ,dont discount a nice 309 goodwood or mint 309 gti there great fun .

Iam collecting my Mi's at the weekend and will drop one in the 205 through the winter after ive rebuilt it with the obvious tweeks you know i am into .....Project 200 .......the other i will play around with and maybe go mad on .......

Dazza..
