B18C7 turbo.....dont use AVO.....read on....

[Lukezen27]

james is his tuner

BLKCRX James?

[krogoth]

^id say ur correct

[Lukezen27]

^id say ur correct

Well if its the same guy he sure should knows what's hes doing...

I've following his stuff and read about it for years lol

I'll keep quite now

[Limbo]

have a read of this one

hmmmm dunno then, after reading the post from Hondatech (which is Jame's site) i was pretty sure that the more you advance the more detonation you would likely get. SOmeone else have a read and let me know if you come to the same conclusion

[Limbo]

dunno now i'm totally confused. I'll have to talk to Adrian next time and ask him also what my tune is like. I forgot where i put my dyno charts.....

let us know how you go anyway.

P.S - i'd put a bigger turbo on you car anyway the T28R is abit small for a 1.8ltr. a GT3 or GT28RS would be more like what you would want

Guys a typical Honda engine from factory will run 26 to 28deg on the factory ECU for 95 octane fuel at full throttle

A tuned Honda NA engine on 98 octane fuel will run 32 deg give or take what it likes.

A boosted Honda engine at 1 or 2 psi easily run 30deg

Going by principle you regard the ignition 1 degree for every 1 psi you come up with this, assuming the engine likes it…

3psi = 29deg
4psi = 28deg
5psi = 27deg
6psi = 26deg
7psi = 25deg

Now for Tom to be running 20 deg on 6.5psi and still having ignition problems, and is required to run 5 deg ignition timing to stop it from detonating something has to be mechanical wrong.. or as Tom puts it the AVO kit he has just isn’t suited for his car, buyer beware.

To cut a long story short Tom’s setup and combination isn’t correct, building and designing engines to make power requires more than internet research, I think this case just proves it even more, clearly the turbo is to small as Tom has already started, and his tuners experiment on the dyno proves this, I think AVO sold him the wrong turbo, with the wrong exhaust wheel to flow the necessary amount of air required on a turbo Vtec. I guess this is why Tom said in his first post his tuner has recommended his next stage is to change the turbo for a larger one to solve the problem, bring on a GT30 or larger.

[fatboyz39]

how much do the AVO kits go for?

Seems like the turbo is the problem. Put a big sucker on there like GT35R.

[jimmeh]

Tom already knows the turbo is the problem, 5 pages of discussion on here to come up with the same conclusion Tom already had in his first post…. Pointless.
GT30 or larger with a nice manifold … AVO SAY NO

[krogoth]

so its not a AVO kit problem then?

its just being a bit too ambitious with a kit suited for 140kw or so right?

so if the boost was scaled back to bring back only 140kw or so then it should be ok right?

and now with a larger turbo and manifold and a re-tune, everything should be fine again, hopefully

[jimmeh]

I think the whole point of this post is that the AVO kit IS the problem, the turbo kit in Toms case is not sized correctly for his setup.

[pornstar]

lol, this is funny. So many cars run them with no problems, i dont get it.

i also dont see how 2psi makes 170kws, even if the dyno reads high.

thanks for clearing things up jimmey....................

again guys, just like my first post, and jimmeh's response................

the conclusion is that the turbo is too small.................

for cost of AVO kit, i paid $4500, i got everything from them, except ecu and injectors................... including in that $4500 i had the rear exhaust housing machined to 0.86.................but again... the issue is that avo does use this kit well..........but wont claim any more power figures above 150kw................

like deanno mentioned, they (avo) run very conservative as they not honda nuts/specialists, where as our tuners have the knowledge and RnD to push these motors a lot further without any problems or fear of anything going wrong............
