I am considering the GT3076R and GT35R as a street car setup on my entirely stock K20Z1 (06 RSX-S). What will I be looking at for spool time (RPM's)?

Is it possible to put down 400whp on 93-gas w/ no meth/water injection TOTALLY STOCK MOTOR (other than headgasket/ARP headstuds)?

Yes it is possible. You might also want to check out the Borg Warner S258 and S3xx series...they're comparable to the GT-R series without the water lines and having to bother with the BB CHRA.

Wouldn't I be looking at much slower spool time though, or am I wrong on that.

That's the common misconception...just because its non-bb, doesn't mean it spools slower. The transient response (recovery after shifting) may be a tad slower, but overall, the turbos are basically the same. The lack of a BB CHRA means you dont have to spend the few hundred $$ on water lines. Also another factor that people dont consider is that BB CHRA's can't be rebuilt if you ever had a problem

Umm...Water lines don't need to cost a few hundred dollars.

(2) 14mm x1.5 to 6an fitting $12
(2) 6an push lock hose ends $12
4-6 ft 6an push lock hose $20-40
(2) brass tee's $15

you get the point, sure you can do it with kevlar line with crimped ends...but theres an extreme to everything..

Baller -an lines sure do...most people seem to have them. I know you can do it with less money, but you get my point

Not everyone needs a bmw to get to work ..You get my point, It shouldn't be a deciding factor.

FWIW: I've ran a Garrett without the water lines for almost 2 years now, no issues...if price is an issue..

bigbadboy

the BW out performs the GT's so that is also a plus

CTGrey06RSX-S

..So should I not completely rule out an SC61 then for the $ ???

also, can anyone give me a more specific answer on my 2nd question...
Is it possible to put down 400whp on 93-gas w/ no meth/water injection TOTALLY STOCK MOTOR (other than headgasket/ARP headstuds)?

With a GT30 you could do it with about 11-12psi. I'm not sure how far people are pushing stock kseries. On B-series the general rule of thumb is not to go over 300whp stock internals however you see crazy stock numbers all the time.

If your goal is 400whp don't use the gt35. The gt30 will make 525-550 whp around 23-25psi

CTGrey06RSX-S

My appologies.. I should have mentioned, I am aiming for 400whp on stock internals for now... In the future I'll go forged and want 550-600.. (that won't be for a while though).

bigbadboy

you can make 400 on a completely stock motor without having to change the HG or studs it just has to be tuned right.

CTGrey06RSX-S

If it is tuned right... can you make 400whp reliably on a k20 as a street car?

Absolutely. I think 400whp is very safe on a stock K.

I would look into the Borg Warner lineup. They are very good quality and seem to out perform the Garrett units in every way.

CTGrey06RSX-S

Which Borg turbo models specifically should I be looking at then as far as comparable HP to the GT30R-35R?

Schister66

S256/S258 and the S362/S366 will compare with the Garrett GT30r and GT35r IIRC

PM The Shodan or Turbodano for specs and prices

I have a friend that has a precision gt35 and didn't run the water lines. His turbo lasted 10K miles before seizing up. I'm supprised you made it two years.

s366 blows the 35r away hands down no comparison.......... 80lbs min vs twhat is the 35r 65 lbs min? **** BW s258 is up with the 35r

i have an s256 and vs the 3076r the 76r wins spool time barly like 300 rpm faster and past 23-24psi the s256 woops the 30r on high end HP by atleast 50 hp..... i dumped the 3076r for my s256..... and i have no complaints

T4eg

the 35r is a awesome choice for stock motor it spool great on a stock k20a2/z1. I used the t4/67 hit 24lbs by 5600 3rd gear and made 600+ on stock block just with arp headstuds. I would just buy a new oem headgasket and do headstuds then find someone capable of tuning it.

kseitz1

there was just a test on the gt30 vs. the BW.
I vote gt 30
check it out for your self

mini-cRx

quick questin what turbo BW is the direct replacment for the gt35r t3

Schister66

The S362 or S366 will match it in power and spool...up top they may actually surpass its overall power capabilities. The S258 comes rather close to the same power and spools similar to a GT30r. Its a good option if you want something streetable. The S258 is a 60lb/min and has an 80% efficiency island for a good portion of the map. Its definitely one to look at
