I know 2 guys who upped the boost+had the ecu chipped and initially put out 200bhp easily+safely, one of these guys had the boost turned up more pushing out 220bhp, but did not head the advice that he would need to have forged pistons, this ended in tears. if you think your gonna put out 250bhp you need forged pistons and bigger injectors, are you replaceing the manifold? the original is too restictive, ditch the cat and add a de-cat pipe, you can do a change over for the mot. I have read alot of sorry tales regarding modifying this engine, it wasnt designed to be "fast" but for shear pulling power. Oh, are you getting the brakes upgraded? it will be a must!
Hummmm.....
Hi Chap,
Right what I have thus far...... T25 Hybrid, Ported Manifold, new cylinder head, Full stainless with Decat, Turbo Smart FCD, APexi Turbo Timer, boost set @ 12p.s.i max.. next on the list is a FMIC and Larger Injectors, bigger fuel pump and piggy back ECU...
The reason that the pistons die, isn't because they cannot take the boost increase, its because the charge temps are tooo high! The stock IC is not efficient enough for applications above 210hp, the tube and fin design is good, they are just too small and the plastic end caps do not do any favours, with the stock cooler removed and an FMIC introduced you then have the available real estate to mount a larger capacity alloy rad which will help with the extra cooling.
What you have to remember is that as a rule of thumb any engine can take a 50% increase in power, the problem comes from poor thermal dynamics.. e.g. charge temps, cooling system and exhaust system... you address these properly and you will be surprised how much this block on stock internals can take.
Pieter @ DP Engineering in the netherlands has been involved in modifying PSA engines for a long time, and one of his systems which include the following:
GT2860RS BAll bearing Turbo Charger
Love v2 Exhaust manifold
3 bar map sensor
330cc Injectors
FMIC
With a remap
Produced 270hp on stock internals, he even knows of a 300hp XU10J2TE on stock internals... there was a guy on the 205oc that had a stock block and pushed 300hp from it, does anyone remember the post?
Ecosse IMHO do one thing well, and thats over charge people.... £1800 to supply and fit forged pistons WTF if you look around that is like 4 more SRi/Executive turbo's ! !
I honestly believe that with the right set up this car will run 250 reliably... very, very easily!
My last Turbo maxed out @ 28 p.s.i before the oil seals gave way.... the pistons are fine... no problems.... now that's 28 p.s.i on stock everything, cooling and charge cooling and fuelling.... so I think they can safely take 1 bar with the extra cooling and fuel to produce 250hp.
Well I got my service kit from Conceptua Performance Tuning off eBay, but as yours is a KKK you might want to try Melett
