I am happy with my sc61 its oil cooled only and is equivalent to the size and specs to the 35r. I have over 10,000 miles on it and the shaft is still true and not moving. turbo timer ftw.

 

buddy just up the street has a SC61 as well... he likes it as well, tried and true I guess. I hope to make better use of the 35R I have in my car. I'm wanting to hit 450hp that at least would make me feel like it's being used better. Probably be a lot of fun too.

I'f I'm not mistaken the SC61 is comparable to the GT40 in 56 trim. Thats a big boy turbo right there.

oh oh, after more thought I would retract my GT28RS recomendation even at 350hp BECAUSE I think the turbo would be in choke mode anything after. That being a huge issue on s2000 I think the proper size would be GT30 or R, just comes down to money at that point. I think that's the best honest choice for the application on on hand.

 

If I were you, I'd just go right to the source and call Ya at Inline Pro
They've R&D their Kit and they're quite aware of what gains can be made by using various Turbo's w/ their equipment. This will save you time, money and undue stress later down the road.

 

Make the BOV sound louder.... what a bunch of BS

 

[QUOTE=05TurboS2k]As far as the GT28 goes.

 

[QUOTE=05TurboS2k]perhaps you'd want to rephrase this (speaking about the GT35R)
"""""but it also won't require the same boost level to reach 400 rwhp as a GT30""""
You'd weight that heavier then the low/mid gain he'd get having a gt28/30????
Who cares about how much boost he'll have to add to hit the number, boost is free up to 10psi which would hit his numbers anyways.

 

[QUOTE=05TurboS2k]In general sure the larger the turbo the more efficient for one reason theres less blow by.

 

 

""""but less boost pressure to move the same amount of air""""
lets talk flow not "boost" thats really the wrong way to look at this, boost is the RESULT not a variable" You can't define a variable with the same variable. So yes the GT35 will produce higher boost with less air flowing by the compressor wheel as like sized turbos. Thats a result of it being very efficient there's no argument there.

hey don't put the BOV louder thing on me only lol.... I laughed when i first heard it to....the same car on same EXACT setup proved me wrong. I had nothing else to say when I saw it. GT30R will hit 500hp more then he'll have to add a head gasket or with a bit of a scary tune try to push the low boost side. At this point I've been told people have gotten away apparently with 14psi on stock HG (NOT that I'd recommend above 10) which would hit well over 400. Fact is the numbers he's looking at put him on the edge either way. It's why again i'd recommend either going smaller (GT28) at 10psi and stock HG making a VERY streetable car having 11.1:1 compression and no lag at all hardly. OR bump to a GT30 size and go 2mm allowing him to push the motor to all its capable of on stock internals anyways (500hp) Why get a bigger turbo then he needs. ONCE AGAIN. Stock psi isn't going to matter at all on the 2mm as 20psi is no matter on the 2mm cometic. In fact Blues2K3 runs 27psi (safely) on a 2mm according to what he's told me. I don't think he'll hit the 400 number with a stock HG period. I'm on a GT35R myself and know of another whos doing better numbers then me but still even on a (dynapack) happy dyno not hitting over 360hp either. This all said.....

GT28RS for the 350hp number stock head gasket 10psi
OR
GT30/R for <500hp and a 2mm cometic, any bigger and he'll need internals

FTW.... once again. I don't see how this part of the argument has been changed the 35R still is gonna spend a bunch of money that just isn't needed, though its more efficent it still isn't going to produce the boost levels that a GT30 is through the midrange, as far as the top end goes....its gonna produce 500hp capable boost numbers anyways THE LIMIT of the stock bottom end. (unless someone will argue the bottom end can handle more, me personally I won't put the bottom end to stress over 450hp but thats just my own opinion I know others have done it plenty of times)


As far as the bov is concerned, I explained earlier only as it was explained to me WHY it'd be louder. At this point I don't fully understand it honestly but I saw it happen and it was explained to me in (short form) as being the case due to the freewheeling on the compressor wheel lasting longer. Not sure how that'd really be with the hot side loosing its pressure but, whatever fact is it did it on an identical setup. It actually didn't seem as much louder as it did a LONGER hiss, def sounded like more air going through total. Not sure on all that, that's really calc*ing more then I care to at that point I'd just be guessing on why. Oh and church is who backed up the blow by, I read the info off a turbo manufacture company (wish I could recall which) however church is who backed the info on the blow by being less partially due to size rather then anything else. It makes sense to me if you have a GT15 for example the tolerances can only get soo small with the engineering specs we have in turbo tech. If you take that same tolerance and apply it to a larger turbo of course you get less blowing AROUND the turbine wheel as a % of total volume passing through it. I believe I've read a number of diff books that supported this argument and one I think used the 35R as it's example. If you really care I'll source it and quote it. (they were Honda related turbo books too).

 

Envied,

Call Ya @ Inline (and also speak to John if possible) and discuss your options. They will piece together a combination of parts that will work for your goals.

And disregard the B.S. posted above. Too much uneducated advice.
