OK, so I am starting to purchase parts to rebuild my hatch that has been dead for over a year. I am building a D16z6 with Vitara pistons, and a stock rebuilt head. I would like to see 250-300 whp...I have found a decent buy on a Garrett GT1752 .53 / .47 & was wondering if this is a decent turbo for my goal? It's from an 03 Saab. If this is a good turbo, what is the bolt pattern on it, i.e. t3, t4, etc? I know I'm an FI noob, and I freely admit it. I searched here and HMT to no avail.....TIA

That sounds like a turbo they would put on a bike (I've been looking into it for my R6. Found a kit that uses a GT15).

I don't think it would give you 250-300, but it would give you a lot of low-end torque.

Thanks. I know this is asked all day everyday, but....any suggestions. I am trying to do this on the cheap, but I want something good. I am not trying to be a street racing king, or a pro drag racer - I just want a fun realatively cheap weekend car that I can take to the strip every now & then, etc.

I was looking at a GT28 for 250-300whp, but since I've gotten the bike my plans have changed some.

I like the GT series because they're supposed to spool incredibly fast, but they're out of my budget right now. ($1200ish)

I'm here to listen to suggestions from other members for a 250-300whp turbo now.

that turbo is from a saab 9/3 it is a small turbo and it is rumored to flow 23-24lb/min(no hard data) so your looking at 240 crank tops. so maybe 220whp at best. it has a similar flange to a t25(same bolt position but has a different entry which can be port matched) I have one of these turbos that I was going to use on a DD but decided against it. i'd let it go cheap if interested but it's not going to fulfill your goals. now a turbo that is affordable that should obtain your goals is a t3 60 trim (or even a super 60)it flows 34lb/min(36lb/min for the S60) and I'd reccomend getting a .63 a/r housing if you plan on spinning the engine high in the rev's or .48 a/r if you want more responsiveness in sacrifice of top end power(I have a rebuilt .48/60 i'll be putting on ebay soon) now if you have deep pockets i'd say gt28rs all the way. ps if you don't understand lb/min i'll break it down real quick. most engines make between 8-13hp per lb/min of air. honda's typically are in the 10-11hp per lb/min and if you get a cam and do some head work it will be closer to 11-13hp per lb/min hp rating are in bhp(crank) and subtract about 11-15% loss through the drivetrain.

Would that size turbo be good for a 600cc bike motor? Just wondering.

edit: 16-17k redline, if that matters.

Sorry for the OT.

Oh, it's only a matter of time before it's boosted. I'm a boost freak. If it has the posibility of being boosted I'll put a snail on it. Almost boosted my brother's pocket bike, but he ended up selling it.

No worries - I think I may be putting the car before the horse w/ this question anyway

I wouldnt even know where to start on mapping the VE of a high rpm engine. but i'll give an educated guess at it. lol. well lets go with what is known. hrc uses a 16g on there busa kit (34lb/min) but thats a 1300. so lets say you need about half that big of a turbo. so id say something in the 17-23lb/min area would be ideal. a gt15 would actually be a very nice turbo in that range but i'm sure those are pretty pricy. lets look at some other options. a t25 55 trim flows 20lb/min so there's another cannidate(found in saab 9000's) a tb22 (aka 300zx automatic turbo) flows 22lb/min and has a smaller turbine housing so it would spool faster. a kkk k03 from a volkswagen flows 19lb/min so it as well is a cannidate. the gt1752 would also be a cannidate but on the larger end of the spectrum. a mitsubishi td04 9b (3000gt vr4) would be a small turbo that would spool very quick 17lb/min. now one thing to take into consideration is the size the smaller the turbo is the more peaky and unpredictable the bike will be(dangerous in my eyes) and the larger you go the more linear the power will come on (probably a better choice if you ask me) either way don't look to make boost sooner than 7k rpm's because I don't see it happening and still make good power up top.
