Sorry for all questions, but am keen to learn lol whats your opinion on the T16 manifold, any good or do i punt it and head for dp one? not chasing big numbers, 250 - 300bhp is my ultimate target, don't do trackdays just good old pot hole ridden edinburgh roads lol. |

could be l8 not 100% tbh just know he has the one that came out the nile 306 and i helped him rewire it back into his 205 :-)again tho i wouldnt be using it unless you got a custom map on it , as now a days a stand alone ecu is cheap enough and more people could work live with it t16 manifold isnt up to much again its dated but will do for the power your aiming for if you have the money get a dp one tho ________________________________________ SOS Motorsportwww.sosmotorsport.co.uk 450bhp 205 16v Turbo www.facebook.com/pages/SOS-Motorsport/159917677353556 |

i'll stick with the T16 mani the now. as you say its good enough for my goalRe the L8 management, i kinda wish i'd never decided on it, it needs wasted spark conversion etc etc etc, but, its standing me ~ 700 so far, so my chances of claiming that back are slim?? been speaking to a guy on oddkidd creations and he's saying go for P8, me thinks a major rethink is on the cards ..forged pistons, proper ecu etc, if am gonna do may as well do it right even if it takes another 6 to 8 month. do you think Cossie T3 is a good idea, av got a good one. |

Wouldn't personally use such an old turbo... The old garrett T series are seriously old now, 1970s in design. The newer garrett GT series is a much better option something like a gt3071r, less laggy, more flow, less heat. All round, much better units. |

obviously cam specs/timing, mapping and turbo A/R's all have an effect. My T3 is 0.48/0.42 hot/coldsidegti6 cams are fairly wild for turboing, i spoke to a guy at GMC motorsport a couple years back, and he said that the xsi J4R cams would be more suited to a 'road' car running a turbo |

my 8v wasnt anywhere near 240 lol, i had std T25, RFX cam, 4.5 bar fuel pressure reg, and resistors to 'fool'the map sensor. It was 'ok' but they dont rev much, hence the diesel box! |

I am running 454bhp on std cams...And its very useable too with driveability uncompromised. This is supercharged though, but even so proves that it can be done.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone  |

the power delivery is completely diff between turbo and supercharger tho , as well as the torque levels the turbo will produce which makes it alot harder to drive and control ________________________________________ SOS Motorsportwww.sosmotorsport.co.uk 450bhp 205 16v Turbo www.facebook.com/pages/SOS-Motorsport/159917677353556 |

No torque steer, no wheel spinning up, excellent power delivery in a lovely linear fashion. And if driven sensibly can get 380 miles to the tankful. Yes, it doesn't have the same torque as a turbo would produce it's only around 320ft/lbs but maybe thats the beauty of it, you are not fighting the car all the time, just feeding the power in smoothly. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |
