My New 98 gsx build

[C3L1CA]

I think you really need to decide what your goals are Greg before anybody can really help that much. No point to get some huge turbo and a bunch of other baller stuff if your goal is only 500 on a dyno jet.

You have to really pick out a goal for either power or times then go do your research. Then based on your goals go look at dsmtuners, here, other dsm forums and search for threads around your goal level and see what other people have done to reach your goal level.

I understand wanting the best and wanting to do an awesome build but if you only want 500 dyno jet you're wasting a lot of money with some of the stuff you've said so far. Remember if you go for some crazy build to get a crazy built transmission to go along with the power.



For what its worth I loved my bolt on mitsu housing turbo on my fp manifold. No worries about cracking and could've passed it off for stock to a car newb

My wife's old 2.0l 1G with an SC61 on it was laggy. It had a tubular manifold, which didn't help at all with spool, but it was only a .63 A/R and it had a small exhaust wheel compared to a 6262 or 6266. With medium cams and and a typical SMIM it was a pain to get it to spool in 2nd gear. The gearing is so long on DSMs versus an Evo, STI, Supra, Civic, etc that you really drop a lot of RPMs on each shift. I could never quite get the revlimiter high enough to not have it fall on it's face going into 2nd, even with NLTS, but it was a stock motor without a good valvetrain so 8500 was pushing my luck already.

Usually most turbos above the 16G/20G or other smaller bolt-on setups are a big jump in lag. Going from an Evo 3 16G to a typical T3/T4 is big lag increase and then from a typical T3/T4 to a 61mm-67mm is a big lag increase.

I know we live in a world today where on the internet, anything smaller than a 61mm is "small". Forget that bullshit, a 62mm is a fairly large turbo to 99% of us. That turbo is going to shift your power band quite a bit to the right. Add in a SMIM, not sure what you're reading but that will also likely move your power band even more right. Add in larger cams, more right. Add in some tubular manifold instead of the short runner cast one (that EVERYONE is telling you to keep but for some reason you have a hard-on for tubular), and that may move it a tad more right.

By the time you're all said n done, I would predict your setup to hit 30psi around 5k+ RPM. I say that because that's about where my similar setup on my Talon hit 30psi (built 2.0, T3 tubular mani, S362, JMF intake, 272 cams). It's a world of a difference from a 16g as far as lag goes. Which may very well have a negative affect on how "enjoyable" the car is to drive. And this is EXACTLY why all of us are saying to stick with the FP manifold, and go with as small of a turbo that reaches your power goals.

Kerry on here had an FP manifold, and a bolt on SCM61, he out-spooled me and kept up up-top.

I just look at it as.. My new build will have potential to make over 600+WHP If I keep the fp manifold it makes it limited. Don't get me wrong I love that manifold and getting a 5858BB is a great idea, But if I ever wanted to make more power I'd have to buy another turbo and a tubular, If I can afford a tubular and a t3 turbo I mind as well. I kinda just wanna do this one big build and not have to mess with it for a while.

I guess my power goals are around 600whp, But I'm open to whatever that build can get me, I just don't wanna do a build that's built to handle over 600whp and only put down 500whp.. yea know what I mean?

I really appreciate all the suggestions, comments and trying to help me out.

[Yiddie]

And I guess another hiccup I'm trying to figure out is.. Which is better for around 600whp, A built 2g or a built 1g head?

There is a big advantage to doing that though.

This thread reads exactly like a lot of threads on here from 2004.

From memory strictly modified was running a beefy t3 turbo with a t3 to mitsu adaptor flange on their red 2g.

That car went 9s and pretty sure it made a little over 500 ;) Think its a pretty good flowing manifold for the money

600hp on what dyno? Kerry made over 600hp dyno-jet on an FP manifold and a regular old SCM61, think it was internally gated too.

Something else about tubulars. They look cool and all, but it also comes with some unwanted complexity. Rather than 4 bolts on top of the manifold, easy to get to, to attach/remove the turbo, you now get to deal with 4 bolts underneath, that are a pain to get to. They might come loose so you have to go under there with an allen or whatever to tighten. installing the nuts to attach the mani to the head, depending on the manifold that can be a PITA. You will likely have no heat shield.

At least in my experience, the more I mod and put in aftermarket stuff, the more I appreciate OEM quality and designs. And the more I appreciate keeping things simple. Not always the case obviously, but often the case in my experience so far.

Just my point of view I guess, everyone will have their own. Good luck to you whatever path you choose.
