potential is potental no matter what the set-up is. We are not talking about shiftpoints here. However, now that you mentioned it....you could not be more wrong. I shift and about 8k in EVERY gear (1-3) not just into 4th. On a stock block the is high. On a built 2.0 you have the abilty to go higher. If it is called for.
Again, you are wrong on your statement on not needing revs on a gt35 or smaller turbo. Do some searching on the subject.
oh...you want powerband? I got your powerband.

1-2: 6800
2-3: 6600
3-4: 6500
4-5: 6000
Taking it all the way out to 8000 doesn't do you a whole lot of good.

It's funny that you type about high revving and needing high shift points and then showing a dyno graph like that. Based on that chart, your optimum shift points are around:
1-2: 6800
2-3: 6600
3-4: 6500
4-5: 6000
Taking it all the way out to 8000 doesn't do you a whole lot of good.

I agree with you somewhat. But, we do loose time by the 4-5 shift. So going up in the rpms through each gear help prevent us from crossing the line at an unsafe rpm without going into 5th.

In regards to a stroked GT35R car needing revs? I've posted several engine dyno graphs and asked for opinions on when the optimum shift points are. The results were around 7500 RPM. What this tells me is all this complaining about strokers not being able to rev is pointless because you don't need to rev a stroker past 8k unless your running bigger than a GT35R.
Rather than telling you that you are wrong and to do some searching on "the net". I'll point you to this thread when I was trying to puzzle out the best place to shift for a stroked GT35R car.

OKIX.. no doubt you have a great powerband. How you run 10.8 with a Green totally amazes me. My friend could maybe just squeeze a low 11 out and he is in a much lighter car (Evo 6). Perhaps there was some mis-communication... I think a 2 litre + Evo Green is a great combo. It's for turbos any larger than that where I think the stroker makes sense.

However, if i was to run a 2.0l vs a 2.3l with a 35r I would still run the 2.0l. for the rpms. I believe bigger turbos like more rpms.
anyway makes for good internet conversation.

if the blocks coming out then pretty much yeh, re boring has to be done either way etc
however if you dont have too much milleage you can drop in rods and pistons in situe, best way to retain the stock harmonics of the engine the best you can, less things get changed less things can break.

OKIX, You say bigger turbos like more RPMS as in they like more flow? well a 2.3 will flow more air at a lower rpm so whats your point.
Keep in mind were not talking about 42R's. Were talking about 3082's and 35r's and 6776's and maybe a 4088.
Also my revlimit on my 2.3 is 8500. I only rev to 8 though. A few people i know have spun 2.3's to 8.5 - 9k. I spun a bearing in my car and at the time a 2.3 was cheaper so i went that route. I also at the time wasn't planning on touching the head. Now i wish i had done a 2.0L and was looking at just a head upgrade and a 4094. Insted I'm prolly going to go to a 6776 or a 4088.
A 2.3L evo on the street daily driving is so much more driver friendly than a big cam 2L. If you have a drag car, or a IX do a 2L if you have a daily driven big cam VIII a 2.3L will be better suited for a daily. Also my car sounds and feels so much different than my friends evos. I don't know if its the Tanabe 3.5inch exhaust or what. I never herd my car with exhaust on just a 2L.

Get the 2.3L ... unless you're going for 1/4 mile records, it'll be more rewarding to have the earlier spool/better torque of the 2.3L vs. a 2.0. I have a built 2.0L, and if I had to do it over again, I'd get a 2.3L with a 35r.
