My VPE .56 trim/GT30 BB hits full boost by 3500-3600rpm with 272/272 cams. The 2.4L will drop that by 1000rpm. Hopefully I'll be able to tell you for sure soon.
You have the smaller 700177-12 aka HKS GT3037 56-trim 55 lb/min wheel though right? Not the 56-trim comp wheel orginally from the GT35R that I assume we have been talking about. [/b][/quote]
Oh shit, my bad, you're right, I got the 55lbmin set-up. I thought that was the size range we were talking about. Is the FP3065 using the bigger wheel?

Yea, the FP3065 and SC61 use the 61mm GT35R/GT40 comp wheel. The FP3055 probably used the same wheel as in yours.

Good to know, thanks.

I am also going with a 2.4l and a GT56 wheel (SCM61 with TO4S housing) and I am hoping to see full spool at around 3800. The 50 trim is a great pump gas turbo, but the GT56 wheel is nearly identical, but flows more. For the money it is hard to beat a PTE turbo.

What are you guys going to do when you get a 60 trim and you want something bigger or faster? You cant just slap on another "bigger" turbo. Its sad to see all the mitsu and small turbos disapear. Like 10 people up and copied each other on the 2.4 ideas and 50 trims... I think thats oh snap. No one really copied anyone but its all being done at the same time...

I will carry on the 16g tradition. In a slow way too ;)

amen.

The 2.4l just helps make a car a bit more street friendly with a big turbo. A 2.0l or 2.14l is probably a better choice for an all out drag car.

I don't really understand what your saying or getting at. The turbo that we refer to as a 56-trim is a fair amount larger than the one commonly called a 60-trim. So a lot of people have already slapped on larger turbos than that. 50-trims and other wheels in that family have been around and popular for a quite a while now as bolt-ons, the old Franks are ancient nowdays. A lot of us went through our 16G phase years ago and wanted more and moved on to bigger setups over time.

Yea they have been around for a while but everyone is jumping at the same turbos at once....

Pretty soon people will put some other engines and turbos in a "dsm" and still say its a dsm. I dont know maybe its just me but alot of this bigger is better stuff just doesnt cut it for me right now... Some of the people dont even go throught the 16g or little bit bigger phase... they just jump into a 50 trim or a 56 trim and think they will run 11s. Its fun to watch though.

Im just saying whats past a 56 trim or bigger than that. Is there an end to turbo upgrades?

People used to try all kinds of wheels and turbo, but it has been proven over time that some turbos just work better, which is why you see wheels like the 50-trim used in so many turbos now.

Well, a 16G isn't a huge step up from a 14B. You don't have to goto one to run 12s. This board probably has a higher per capita number of people who actually ran 12s on the 14B than most. Cher, Adam, my girlfriend and I dunno if anyone else ran 12s and some decent mphs on the 14B. My gf went from the 14B to a 50-trim. A 16G just wasn't a big enough step at the time and a decent 20G is often a bit more expensive then a Garrett hybrid. A 50-trim is a fine street turbo though, it isn't anything that crazy. The 56-trim is quite a step up though, that wheel flows like a T61. Nobody should be stuck between choosing a 50-trim TO4E or a 56-trim GT40, they aren't exactly in the same range. There are atleast 5 good compressor wheels inbetween those 2 sizes that could be used if you wanted something a little bigger than a 50-trim T04E.

There isn't an end exactly. The turbos we use are small compared to what find on bigger displacement cars. The 60-1 is pretty much the starting point for the Supra guys. With more displacement, higher rev ranges, nitrous and new turbo technology people will keep trying to put bigger and bigger stuff on. Doesn't mean we will go fast though.

For me, I started with the 16g and it didn't take long to know I wanted more. I know how much power I want to make and it just doesn't make sense to keep spending $$$ on the "next size larger" turbo over time. Make a power jump that's worth the $$$ spent. Either you want to have a stock to slightly modified car which is easy to drive on the street or you want to go as fast as possible. Some people buy the "big" turbo knowing that their present mod list will not take full advantage of it, but are working to keep adding parts to support it. For me, I never really thought I would need a larger turbo than I have now, but I'm starting to think I'm wrong about that with my 2.4L getting ready to go in.
