The 3575 is a 75lb/min compressor. If it was a 75mm it would flow a lot more. Sounds like your 4g ran pretty good.
[/quote]
I have never ran the turbo or anything, but it seemed pretty massive and 75mm seemed about the right size, so I just assumed that's what they meant. 75lb/min sounds good too though. I'll go check out FP's site and see what it's all about. I could never make use of a turbo that size is all I know. It was on a ------- 1G Gayser on a built G4CS that made a tad over 600whp (verified). 75lbs/min or 75mm either one sounds about right for the power it was making. Doesn't the smaller GT42R (like 94mm or some ----) support 800-900whp?
My 4G is a great motor. It's the 1992 6 bolt which IMO is the best year for DSM's. Yet again I have changed my plans so it's sitting dormant in my driveway. It's had a bunch of turbos on and off it and only been up and running off and on. I'm always changing ----, not to mention I have a suspened license so it's to my benefit to let it sit. The DSMLINK reading(s) were most likely semi-inaccurate, but it was fun knowing that I was actually making some sort of decent power.
I have a couple decent snails lying around I may do something with or perhaps I'll take the motor out for a freshening and do some rewiring and make it perfect or whatever. It's a 2G so the 6 bolt swap harnesses that had to be made are due for a thorough look over at the least lol. IDK, I'm just kind of burned out on cars for a second and need to put funds elsewhere so I can actually make $ instead of spend $. A 2G is a nice looking car, and the performance of the 4G is incredible, but the lack of any resembelance of refinement is what irks me. If I'm going to start dumping thousands on cars again I want it to be something worthy, but ---- a car payment and I don't have $40+k to drop like it aint no thing. OMG NOVEL JOHN GRISHAM WTF BBQ BIE 2U?!

Re: SC61 vs. GT35
Just where a DSM belongs ahahahaha. Parked in the shop with rusty rotors from not being driven in over 5 months, as indicated from the Blizzaks for winter lol. IDK what all the weird circles and ---- are in the pic, the car is actually 100% straight except for a tiny dent I think is visible on the rear panel about the size of a dime. Definitely needs a bath. Meh, everyone's seen a black 2G lol. Just thought I'd give the piece of ---- a little spot in e-land.

Here is my POS 7 bolt 4g64/63 hybrid . I can't bring myself to deal with FWD so Honda is out.

Re: SC61 vs. GT35
Hell yes, Black 2G's unite! That's a cool little 2.4 set-up you have. Most people shy away from that and do the G4CS, but yours has more character. Thanks for the info on the bigger turbos too. As you can tell I'm not too experienced with anything but MHI's or bolt on variations. My motor is not nearly as built as yours, but it's held together well. Stock 2.0 block with .20 over 8:5:1 OEM pistons on 1G "big" rods. It has the arp/metal hg/BS removal/kevlar belt treatment and the oem rebuilt head, but that's about it. I can say without hesitation that I have beat the hell out of it and even subjected it to some serious knock (rofl) and it's held up to everything I've thrown at it. Before the rebuild it was a low mile Japanese import, but the ------- thing huffed a valve going up a slight incline in 5th gear (go figure).
Anyway, what are you using for EM? ----, with the 4G64 you could be getting all crazy with the Haltech or super bawlerz Motech ahaha. IDC what anyone says. Yes, DSM's have lots of retarded little nit-picky things go wrong, but pound for pound the motors hold their own. I'll always have a soft spot for my old money pit, but I'm too old to spend boatloads on a mid 90's Jap car. Besides, DSMers are, as a whole, turning into a bunch of ricey little fuckasses who think their reverse indiglo Faze boost gauge and Hallman MBC make them the hottest ---- next to a Diablo
. The good old days of DSMing are gone, the smart ones are jumping ship to either (gasp) an EVO or M3 or such. DEES THREAD EEZ HIEJAXED BY DEM CRAZY DSM GUYZZZ.
AHAHAHA! It's late.

I was running Megasquirt. Unfortunately I am a poor college student( the motor was paid for before I lived with my G/F if you know what I mean) and can't afford a baller EM setup. Hell I might have still picked it since I like ------- around with weird/different ---- and trying new ideas. With the recent developments with MS2 and the DSM cas I'll probably get a Gm alcohol sensor and run E85 and staged injectors when I get it running next time. I was running E85, but was lacking injector size and it was a pain switching to normal fuel, MS2 should solve the switching issue and some 1600cc secondaries will take care of the rest. E85 makes me wish I had gone with something in the high 9s-10:1 compression though, if only I could get it everywhere.
Ehh its late. I should be sleeping.

Re: SC61 vs. GT35
precision claims that the sc6152 supports 630 HP... it has a 61.4 x 82 mm wheel. EXactly the same as the garrett gt35R that is rated at 600 HP
I think precision are closer to the reality. I have eared stories of 600 WHP with the gt35R so it is definitely able of more than 600 HP. on this turbo as well as on other gt models, it seems that garrett are under rating their GT turbos by 5-10%, probably to avoid people maxing them out.
turbine wise, the GT35R is smaller: the sc6152 has a 61.9 x 71 mm turbine wheel. That's stage 5.
the gt35R is 62.3 x 68mm. according to driving comparisons on other turbo models, larger turbine inducer for a same exducer = faster spool up.
not sure if the 3 mm larger turbine wheel base of the sc61 compensates for the lack of ball bearings. i am sure it does to a certain extent, making the sc61 and the gt35R fairly equivalent turbos in terms of performance.
Yes the sc61 is cheaper but it should be noted that it's not watercooled when the gt35R is AND most importantly, Precision have a tendancy to throw a 360° thrust bearing in their turbos without bolting it down to the center section, which makes them less reliable at high boost (over 1 bar) and as a mather of fact, all the SC61 I rebuilt were blown BECAUSE of a thrust failure.

Re: SC61 vs. GT35
I have been doing a lot of reaserch on this same subject. And it came down to about the same turbo one is water cooled/oil cooled ball bearing and the other is 360 thrust bearing oil cooled. Yeah the gt35r will spool a little faster but it is sooooo much more expensive.
SC61 FTW!!!!
I myself just oredered my SC63!! cant wait to get it.

Re: SC61 vs. GT35
yah gt turbos spool faster but thats not why they are so expensive.. the transient power they make is way more than a journal bearing turbo.. you lose less boost between shifts no spooling back up full boost on the next shift on a journal bearing ur gonna loose a few psi never the less and that my friend is a few tenths.. take it or leave it ...
dyno queen =sc61
serious racer = gt35
dyno queen =sc61
serious racer = gt35
