Ideas/lists of Best Performance Upgrades/Mods For My 155THP?? :D

[Joe Danile]

Hi, I am new to this thread writing as so far I have been reading lots of your posts to try find out the best upgrades to make and also learn from you guys and girls !!

I am lloking for a list really of the best performance upgrades for my 155THP, as I have installed the Forge Induction kit recently and not sure what my next step would be to actually make a difference.
My line of sight would be Milltek non-res exhaust but as im just having it for street use, probably resonated is best and then remap.

Any ideas of how to actually get closer to 200bhp :P??

All ideas would be much appreciated.
Many Thanks

Welcome to the club

Sounds like you already have your answer, exhaust and remap should get you in the 200bhp club.

Speak to Jamie at SP Tuning, he'll sort you out

[Joe Danile]

Thanks , feeling welcome already.

Would I need multiple remaps like 1 or 2 or is it a straight exhaust with a remap the answer? :P

Ill check him out and see what he says thanks

Jamie can do the exhaust for you too.

You could probably squeeze it all in one day and then get it on his dyno to test too

[Joe Danile]

Haha thanks, would be awesome! Do you know how long it usually take to fit the exhaust?
Was thinking may be fitting the exhaust myself and letting him do the remapping and special stuff after (for learning benefits) but if he can do it all then super !

Dyno test not sometimes cause catastrophic damage? heard bad things happen before (not to a ds3) aha

Downpipe, Intercooler, Remap.
200 to 220HP

[Jamie@SPTuning]

The exhaust will take around 3 hours to fit, it's the downpipe that's takes all the time, cat back is only 30 mins work.
I can supply and fit for £1200 inc vat
A custom remap on our rollers is £270.00 inc vat.
I can further discount the remap to £250.00 inc vat if you do both at the same time.
There's currently a 6 week back order on the highflow cats
You could go decat as alternative and save £300 or so. MOT might be a problem though.

[Joe Danile]

Hi Jamie, many thanks for the reply

I may be able to sort the MOT part out. But whats the difference from the decat and the Milltek exhaust?(apart from not catalytic converter). As would I be paying for half of the Milltek exhaust and a straight custom pipe or is it part of the exhaust bought in?(apologies for being a bit slow)aha.
Also if I were to purchase the resonated milltek exhaust with the decat, whats the noise level looking to be as I LOVE a non res but dont want to be to loud (as of yet)haha

[Jamie@SPTuning]

We'd fit a straight through downpipe instead of the high flow cat. It will be louder without the cat though. Decat pipe only costs £130 compared to £600 or so for the cat....
earplugs 50p

[Joe Danile]

Hahah! spot on lol
Would that then fit the resonated milltek exhaust from then on out? and make the overall resonated sound louder aha or will it simply be a straight pipe from the manifold to tips?
(learning so much already :lemon

Joe, also think about a Walnut Blast, made a very noticeable difference to my remapped D Sport. In about 5 weeks Jamie will be fitting some stuff on mine so il end up with a walnut blasted, mapped, latest revision HPFP, Milltech exhaust and beefier clutch on my 150 THP.

[Joe Danile]

What's walnut blast superfly ? (Is it like a sand blast?)

[cyclone]

The THP is a direct injection engine meaning fuel is injected straight into the cylinders. As part of all engines emissions system the vapors from inside the crankcase are directed into the inlet air that will go into the engine to be burned. This oil filled vapor passes the intake chamber and valves on its way to being burned. In older engines this was of no consequence as your fuel also passed this area cleaning off any deposits that the oil vapor caused. But as that our engines the fuel never goes by the valves(remember it is injected straight into the cylinder) there is nothing to clean those deposits off and it builds up and up and up. This can cause bad things to happen low power uneven running and worst case a blown engine. The walnut blasting is a process to clean off the deposits without taking off the cylinder head and manually cleaning it. Effective, and relatively quick and cheap comparatively. Jamie has some pics of doing his car on his build thread.

[Joe Danile]

Yeah cheers

There's a detailed thread here on different methods of cleaning the carbon build-up.
