Advice please, Upgraded Exhaust manifold for a V70R AWD Phase III

[Muscas]

I am contemplating improving my Exhaust manifold as I understand there are others available which will improve performance.

I believe I can make use of an XC90 2.5 Petrol or an S60R/V70R AWD(current model). Was also told that the XC90's was better, not sure why??? Noticed that the 2.5 Petrol engine (as fitted in the XC90) has only just been released in the UK in the last 3 weeks.

Is it possible to get hold of such a manifold without paying mega money?
After having fitted the manifold would I require a custom remap? Or is the existing RICA remap satisfactory?

While on the subject of engine modifications, have you guys and gals any ideas on the best way to improve the 19T Turbo?

Looking forward to hearing your advice and comments, thanks in advance.

Hi Patrick, what do you mean by "the best way to improve the 19T Turbo"?

Hi Iain,

What I mean by "improving the 19T" is either replacing or modifying the existing Turbo unit to provide more Boost.

Have no idea what my options are, just fired that question in to see what the response will be.

Patrick, Adieu has had a hybrid turbo fitted to his T5R with interesting results - I'm sure that he would be pleased to discuss the pros and cons with you. Having heard his turbo it has a great chatter sound when the turbine goes in reverse! The recirculating dump valve has been taken off the car because it's not needed with the hybrid. The car was of course re-mapped after the fitting of the new hybrid.

Good day Patrick,

To the best of my knowledge the same latest manifold is on both cars that you mention.

It varies principally in that on the old one, one of the exhaust ports loops up over the remaining four, whilst with the new one they all go in the same direction to meet.

Recently, I took both types to a supplier of mine who specialises in head and manifold work. His opinion was that with some reworking on either you should get a similar result....I had my original reworked.

On the subject of reworking a 19T, the guts of it are the same as the 18T, the difference being that the 19T makes the first turn of the gasses within its exhaust casting whereas the 18T needs the first tighter turn of the downpipe to do that job. I have had a hybrid 18T fitted to my S70 T5, it was an expensive job done by a specialist. I have spoken to Turbo Tecnics about their hybrid fitted to Ian Inglis's car as compared to what their respected competitor did to my 18T and they have the opinion that the effect would be similar with either. You might consider having a specialist of your choosing (there are only two really up to the very best work) have a look at your turbo and give an opinion on just simply machining out a very few parts of the casting and cutting back the blades. This sort of work will be in the £250 plus VAT region on a perfect turbo and will help when the turbo is running near full boost: the very best hybrid work is likely to cost £600 minimum plus VAT on a one off basis where they are machining to take selected larger wheels and bearings etc. and maybe some recon. related bits and pieces. Any firm offering work for less will be offering below par work and materials in this highly specialised field. In this respect the TT hybrid is very fairly priced as it includes some purpose made castings to house some Garret parts in the restricted length available.

In conclusion, my feeling is that the restriction with your car will remain that damned downpipe and the difficulty in making the exhaust gasses pass better through the space available on a rhd car. Bare in mind that many people before you have had specialists look at it who were unable to effect a solution. Replacing the standard cat with a Kemira 'race' version would help a bit.

I doubt changing the manifold will make a significant difference in performance especially considering the work/cost involved.
A simpler way to increase performance would be to increase the boost pressure but I dont know how much more your conrods will take.

Just thought I'd drop my 2 pence worth and say every penny spent at Turbo Technics was worth it.The Hybrid fitted to mine will hold around 1.6 bar all day long but my engine cannot take that higher pressure. So I have it set to 1.1bar which is enough for safe running and a little fun when required. Maybe you should give them a call and just see how much it would cost. To date I believe i'm the only person with a Hybrid from TT fitted to an 850 in this country. Maybe you could become the first V70..........

P.s If you need anymore information about mine just give me a shout.

[Muscas]

Thanks for your replies guys!

Don, do you know how much the replacement manifold would be?
If I did replace it would the car require another remap?

Not really sure how best to proceed, feel as, I have now gone for the RICA, it is restrictive as any major modifications now will require yet another remap or chip and the associated costs.

Hi.

Unfortunately that is the nature of the beast. If you change anything mechanical, then the ECU map is best advised to be altered to suit. Damage can result in using a map not optimised for the mods involved. This is why many people go for a lot of mods at once, to reduce the associated costs.

thats good to know don, i have the nicer spooling 18t on my 850r. My next mods to complete my mod list are a big atech intercooler and a 3" ferrita dp, kemira? cat and ferrita cat back. then i will be at the end of what my car can do without going silly.

ps: are there any 3" cat backs for our cars?
