What turbo for my build? 4g63 guys jump in

[canada4g63]

Ya no... Correct me if I'm wrong but isn't the record on a DSM 499? And that sure as hell won't be easy.

499 in a awd car, close enough to 500 for me. And that set up wasn't really that hard to duplicate, just a great tuner.

gt32 or gt35 (or a holset equivalent would work)

all these people talking about 16g, and 20g, and big t28 must have no clue that those are MHI flanges and not T3 flanges.

i wouldn't have added "4g63 guys jump in" because 400-500 set up on a 420a is not the same as 400-500 on the 4g

Hey, I have a 96 RS and want to turbo it. I'm pretty much a newbie at this but I'd like to know what I'll have to do first in order to get a turbo. I have 5,000 dollars saved up. So, to what could that bring me to? The RS is completely stock by the way.
And yes, I am stupid when it comes to this.

Well for starters, search is thy best friend secondly, you need to build your block, purchase something to tune with (Megasquirt or portfueler), a decent turbo kit or piece one together (buy a kit probably ). Start there and check back

Or take that 5,000$ and just buy a decent gst/GSX!

Why does,"not a bad way to spend 10,00 dollars" come to mind.

Hows this for starters, Fab work but still.http://www.dsmtuners.com/forums/art...uild-420a-stage-2-turbo-kit-under-1000-a.html

Don't focus on horsepower, focus on spool up times... The key word should be daily driven, NOT horsepower. It should feel comfortable and provide full boost at around 3200-3500 for it to be a reliable daily driven machine. Choose the turbo that offers the best possible compromise between spool-up and your power goals, but keep it real and don't day dream. The HX35 should spool around 3,500-4000RPMs and a HX40 should spool above 4000RPMs. I personally have no experience and knowledge with the HX35/40 turbos, Ive always used Garrett turbos...

Remember that cams, manifold design, intake manifold, exhaust, intercooler, intecooler piping, etc affect spool up times...

I'd think you would know that for his FWD setup, a higher spooling turbo would be much better. Daily driven or not. And you were talking about how you beat a "big turbo GSX." That's why there's this thing called brake boosting. I once beat a GT35R STi with my small 16g but he was not brake boosting and I was. It makes a whole world of difference.

Coming from someone who has ran the 20g and 16g at almost full potential, I can tell you now a bigger turbo would satisfy you more. Sure you spool a little higher but why would you want to constantly be in boost while you are daily driving anyway? Top end is key and it feels amazing and something close to a 50trim with the right supporting mods would easily get you into the 400whp mark and again, since you are FWD you want a bigger turbo for traction purposes as well. I can't imagine a s16g or similar on a FWD setup since I already spin all 4 when launching with my s16g.

I agree to a certain extent, I guess it comes down to what each person prefers and build budget. In my book a daily driven fun machine would be a car I can spool the turbo without brake boosting or downshifting. About the car been FWD and having turbo lag so the wheels wont spin like crazy, its obvious that youll spin the wheels like crazy when launching. Theres a thing called a eboost controller with gear boost control. Have you ever race a street machine that spools 7lbs in 1st gear, 14 in 2nd gear, and 21 in 3rd-5th gear ??? Also remember most daily driven machines see cruising races and not 1st gear launch races.

Holset HX35 or 40?

 

[jayson427]

I have a built motor 10.5 compression, crower 2 camshafts and im wondering what would be the best turbo to run on that? Im right around 190 hp now and I only want around 300hp. Any suggestions would be great or personal experience with this topic. Thanks

Something with a larger turbine wheel or higher a/r number on the turbine housing to deal with the additional amount of exhaust energy. A small turbine or small a/r housing will funnel the exhaust energy into too small of a space, raising backpressure and EGT's which are NOT what you'll want to be dealing with on a high-compression application.

Some guys have said a 50-trim, and that would be fine as well....but if it were possible to still get this built, I'd say use something like a 60-1 compressor with a T350 turbine wheel in .63 a/r T3 housing. PTE used to call that wheel combo a SC6052E. That should give you an easy 300whp at just 15psi or so, while reaching full boost in the 4200-4300rpm range and remaining very easy to tune on pump fuel.

i recetly was asking the same question. heres a link to my thread that might help you out in choosing.

 

[Greedy Pimp]

You can make 500whp with E316g, with your high compression, as long as you have supporting mods 400 should be easy with E85, but you can sorce a hx-35/40 all day for cheap.

How long is that evo 16g going to last, not to long if your trying to get 500 hp out of it. Hx35 would be a good choice but if I remember right, they don't wake up till about 25 psi or that might be the hx40. But with the higher compression that should help.

Ok so I have alittle extra money so Im looking into the holsets. Im really interested in the holset h1c. I read the turbine wheel is the same as the hx35 so would this housing fit HX-35 .48 Turbine Housing - DSM Classifieds the h1c? Also with my set up do you guys think 450hp is possible with a small h1c?
