I'm thinking of install the gti6 upgrades to my 1.8 16v engine...So... looking for help... I was looking for tradding this: gti6 exhaust manifold gti6 inlet with 1.8 injectors Now... what will do that going to make in the car? Does I will have to re-map ECU? how high can i put the rev-limit? 7k? It's 6250rpm now.. What do I have to do more? Dont want to open the engine (here in brazil is a lot dificult to find spare parts...) Can anyone help me out? thanksss |

I've heard of people doing this that have got away with mapping but to get the full benefit its best to map, i did an Xu7 before with gti cams and ex man and kept the std plastic intake but fitted xsi injectors (not sure if different i just had them laying about) in the rollers on the factory xu7 map it was only 121bhp but when mapped it was up to 148bhp i later blew that engine and bought a gti6 engine complete as its an easier way to get the power ________________________________________ All South Wales Members Click HereTeam Supercharged Black RALLYE ™ (Click Here for Build Project) MY EBAY ITEMS 07943066306 |

I have GTi6 inlet and exhaust manifolds on my 1.8 16v engine. On a recent rolling road power wasn't up at all. As Simon says, a remap will definitely be needed to get the best gains, however there is a small increase in low down torque. Where did you get yours remapped Simon?________________________________________ '01 Astor Grey GTi6'99 Cherry Rallye |

Throttle response will improve no-end, but I was told by someone on here that it's the XU7JP4 cylinder head that is restricting the power, so if you could swap it out for an XU10 one (either GTi6 or XSi) then theoretically it would improve things...________________________________________ '99 1.8 XS - Sold'00 GTi6 - Killed by armco '01 Cabriolet 1.8 - Sold '96 Eunos Roadster 1.8 Import |

hmmm I was not looking for a "big" change like that...really i was looking for changing both mainfolds and have a gain like 20-30hp... but... like everyone is telling... thats going to be hard... Im going to talk to some friends to make a remape of my sagem... if they can do it... I think I will give it a try... if not... i will just trade the exhaust mainfold. well... if anyone have any more information... im looking for some experience that could give me a light! =D |

My experience with the 1.8 was that the exhaust manifold made a really noticeable difference- you look at the standard one and can easily see why!The inlet and cams made no real improvement at all as the ECU limits the car to just over 6k and the six develops lots of power beyond that. The 1.8 head-according to Sandy -is really restrictive too. To get the benefit of the inlet and cams you need the 2.0litre 135bhp head (or an expensive porting job on the 1.8) A 6 head would work too. A remap would be necessary if only to raise the rev limit. Dixon's race car build demonstrated that a 1.8 N/A engine fully developed can produce 220bhp. ________________________________________ New Forum same high quality intellectual debate!Team Zimmer™ |

Just had a look at my ECU and it's the Sagem model. Is it still not possible to remap these then? ________________________________________ '01 Astor Grey GTi6'99 Cherry Rallye |
