Which is why i am building a 2.2 with some very responsive supporting mods which i am hoping will be well on the way to full boost by 4000 rpm....with a GT35r .82.

what i don't think you're understanding is that sure, you can build a quick car with a 207, but it isn't going to be good at much else except limiter launches and quick quarter mile times....and it will be running on the ragged edge with a low life expectancy. 207 bottom ends aren't that pricey, but the labour to replace/rebuild a bottom end every 10000kms isn't going to go down well with the wallet.

I was hoping the 207 would last a bit longer then 10,000kms with 290-300wkw, and wow u must have had a huge tdo6 coz i was hitting full boost at 4700rpm with a tdo6 and currently hitting max boost at 5000rpm with a gt3082r. I dont track race my car at all (just drag race it a bit) i just daily drive it and its very good at it at the moment and the 80 to 100kw it makes under the curve is more then enough for the 50km/h speed limit zones i drive around in (light gc8

)

A properly tuned 207 will last a long time. Your 5 speed should be smashing every shift according to the general logic going around here.

I wouldn't be worried about boost / power figures. Until a combo is on the dyno, you won't know the limitations. Tune for knock levels and worthwhile gains imo. No point running another 10psi through a turbo if it only gets you 5hp.

Agreed. Just because you have 300kw or whatever I dont believe you will be destroying the engine too quickly. Unless that 10kkms is all track k's.

Im only aiming for a low 11 sec pass and maybe that high ten if im lucky enough and i know a 2.0 is good for that since its pretty much already a mid 11sec car with a bit more aggressive driving, but i do agree for a much faster time then yea bigger motor will be better but for a low 11 im hoping 2.0 will be enough.

Yea with 1.7 bar it only made about 3-5wkw more lol (stock heads

) so we left it at 1.7 bar max and timing has been set to 21 degrees max

less then what they run factory.

sorry, i was meaning if it has a rough life i.e. 10000kms of trying to run a 10...

TD-06 20G, now i can see your goals for the car i understand the method to your madness!

Doesnt matter how strong a block is it will struggle to last more than 10,000ks if trying to run 10s the whole time.

Let me put it this way, i only drag race the car maybe max 20 passes in a year and the usual one gear boost on the streets so wont be trying to run that ten consistently all day everyday.

Also to the OP, keep an eye out for when Tino aka trainwrex updates his thread with his latest e85 tune to see why people build motors!!!!!
