[QUOTE="Boosted98gsx, post: 4247511, member: 588604"] #1 You're wrong #2 You're an idiot #3 Shut up because you know nothing about DSMs Another DSMer coming from Dallas Imports am I. lil_italy you are retarded, and you need to shut up because you know jack about dsm performance. I currently run a GT35R powered 98 GSX that runs 7.56 @ 92 mph in the 1/8th on 20 psi and pump gas. Self wrenched, self tuned. To the thread starter, listen to nothing this idiot has to say, because he is just that, an idiot, trying to strut his e-peen about a subject he knows NOTHING about. Back on topic, to upgrade a turbo you need a lot more than just a GSX. there are a lot more mods that need to be done in the process to get the car prepared for the increased airflow and boost. Fuel being the biggest factor, and what you're going to use to control it. More air means more fuel needed to compensate. What about an intake? The OEM filter box can't flow worth anything, and a K&N replacement filter is recommended as well as a hard pipe between the MAF and the turbocharger (with BOV recirculation of course) to increase laminar flow between the filter and the turbocharger.

I would recommend a 3" intake pipe, and just use a silicone coupler to downsize it to the inlet of your turbo. The 2g OEM blow off valve is a piece. Get an aftermarket upper intercooler pipe with a DECENT aftermarket valve (such as a 1g BOV, or HKS with recirc fitting). I would steer away from Greddy for valves. EXHAUST!!!!!!! There are many designs out there.

Just do your research and find one that is not going to cause oil filter change issues. Next up being a new fuel pump. Only one you can use in the OEM 2g saddle fuel tank is a walbro 255lph high pressure pump. Good for about 450hp worth of fuel. After that, TUNING!!!!! Here's a HUGE important factor. The more you spend on tuning equipment, typically, the better you are off in the long run. DSMlink is the tried and true method for dsm tuning (for timing and fuel control), and can compensate for 1250cc injectors to make them idle and cruise like stock (and still retain decent gas milage, I get 29mpg on my 1000's on the highway with some "play time" as well).

After that, learn how to tune your car for yourself and you are on your merry way to having a happy DSM. Then you can start thinking about the high end performance mods.
