nonBB 50 trim to 35r????

[Robertm1212GST]

Alright guys im running a non BB PTE 50 trim and i wanna go bigger came across a great deal on a PTE DBB sc61 (bolt on gt35r) my mods are FMIC, FP 4" Intake, DSMlink, 850 Injectors, Crower 272's Cams, 3" exhaust, Walbro 255lph, Aeromotive afpr what are your guys thoughts on this turbo on a stock 2.0 motor with these mods?

Wideband, boost gauge, ARPs.

No wideband i have a boost gauge and putting ARP's in before the turbo.

I don't know the gt35r is a pretty sweet turbo but with the stock bottom end you better not cranck that boost controller more than 15psi, otherwise you will have a big BOOM

 

[No_Skillz]

With ARPs and a good tune you should be able to push past 25psi.

So running this turbo on the stock block will be ok? Also do you know around about when it will hit full boost?

What hp goals are you looking?

Going to a gt35r with little done and a stock block is not a good idea. If you're thinking it can put out 600 hp+ on a stock block it cannot. The most I've seen on a stock block is 400-450 hp but you don't need a gt35r for that and everything on the block needs to finely touched perfect condition to take that beating.


I'd suggest you look into the holset hx35 or bw s256/258 it is cheaper, more reliable and spools faster.

And I'd suggest you check-out the posting on hp on other DSMTuners' car for further reference. DSM Dyno Sheets Database

The stock block is pretty strong. The weak link is the headstuds. Many tuners on here are making great numbers on ARPs and an OEM composite headgasket. I can't say for sure what rpm full boost arrives at since I have no experience with a sc61 but I am hypothesizing ~5-5.5k.

Sorry i also have an Composite headgasket aswell ha

His 50-trim can bend the rods in his motor right now.

What's the point of going bigger when you can't handle what you have now. Did you find something useful with all that gt35r lag?

You've already been asked, but again, what are your goals?

 

[Robertm1212GST]

I wanna be in the 500-600hp range im planning on building a motor once this one goes.

With that being said, I agree with dsm-other. Getting 500-600hp out of a completely stock block is highly unlikely. It's not the turbo doing all of the work and if you're planning on building a motor go to the motor build first and the turbo.

No wideband i have a boost gauge and putting ARP's in before the turbo.

And for the least of it all, get a WIDEBAND. A wideband is the most important gauge if you go to that level. Setting the bar that high without a wideband could leave a destruction to all of the money spent.

 

[Robertm1212GST]

Alight im going to look over all the dyno's i mite just stick with the 50 trim for now untill i get the 2.4 built.

Thanks guys

I totally agree. However, I've given up on using logic to discourage people from finding the biggest and baddest turbo they can get their hands on. I was only asserting that at least ARPs are a must when it comes to internals.

 

[crimsondragon]

Only cause you just blew your own head gasket on your stock block Mike.

 

[No_Skillz]

Right... so what I'm saying is that ARPS are a MUST.

 

[dsm-onster]

I agree with your frustration. Logic doesn't go along with this new generation of dsmer guys. At least you know they're trying new things .

Hey hey hey HEY. Just how "new" do you mean by THAT?

I just got done throwing my gt35r on my stock block/head and that was upgraded from the stock 14b and stock everything else...injectors/fuel pump/intake/exhaust manifold/Intercooler/bov......everything.

So far throughout the summer I have got the boost up to 20psi and it holds great and pulls good. Right now Im just fixing some boost leaks and Ill be hopefully pushing 25psi before winter comes and hopefully with a timeslip. I plan on seeing how far I can push the stock block/head before I build it over.

Please don't do that. The boost leaks are at least fooling the ecu into thinking there's more airflow and overshooting the injectors big time; probably the only thing saving your engine from destructive detonation right now. I can't imagine that you're not hitting fuel cut. The t25 not 14b is stock for a 2g car. I hit fuel cut with the 14b with my car at only 16psi. Most if not all manage fuel cut by this point. The same gram/rev number a 1g ecu sees and cuts the injectors is the same number for a 2g ecu. The gt35r has a larger turbine and you're running 4 more psi than that. You most certainly have a higher airflow at 16 psi than me. Unless you have an ebay gt35r.

 

[viperlp01]

wow... 35r at 20+lbs. hmmm I guess its only a matter of time. my buddy rod knocked in 2 weeks from pushing his 14b to 20lbs w/o mods. The new generation...

His profile says he has DSMLink and 1050cc injectors, but his post says stock everything....

He probably assumed that the guy listed all mods in his post. However, he hasn't yet gotten close to the max efficiency of the 35r and only claims to plan on running 25+psi on his totally stock motor, so his post is a little lacking in information and somewhat irrelevant.

And he also does not have ARP head studs. Headgasket will be obliterated soon past 20psi.

I went from a Non BB 50 trim to a GT3561 which is a Nob BB 35R.

I liked the car alot better on the 50 trim, it was just alot more fun to drive on the street. Full spool was bumped up probably 3-500rpms but you also have to try alot harder to get into boost. The extra Lag on the 35R took away the fun of the street car for me.

At the track the extra lag after the shifts killed me ET. I ran 11.8 at 121 on 24psi with the 50 trim and 12.2 at 123 on 26psi with the 35R (was done with low timing and a few boost leaks)

If you don't nail the 1-2 shift then half of 2nd gear is spent re-spooling the Turbo.

If I could do it all over again I would have stayed with the 50 Trim.
