Gs Gs-t's?

[jdmcivic28]

I dont know alot about eclipse's.So i wanted to know if the gs-t/gs-x has an external wastegate?And does the gs have the 4G63 engine in it, or is that only the turbo ones?What hp does the gs run?And what hp for the rs'? What i want to do is turbo a gs, i want to make my own turbo kit with an external wastegate.But if the gst has an external gate i wont have to buy a gs and make my own kit.If you can help that would be cool.Thanks!

The gst/gsx models (after 95) are the only engines with the 4g63. They already have 210+ hp and if you want more are easily upgradable. The gs model has the chrysler 420a in it. it's a 121 cu in 4 cyl. Still a good engine, but only putting out about 160 hp I believe. You can turbo the gs, custom if you have the knowledge, or you can buy prefab kits. Hahn racecraft, and star performance make the best. You can't take the parts from a gs-t and just strap them to the 420, they sit differently in the engine bay and the manifold won't fit. The rs has the same exact engine as the gs. It just doesn't have 4 wheel disc and I think the suspension is a little less beefy. If you know someone who is good you can have them make you a custom manifold for the gs, or you can buy one and strap on a turbo. Just be warned, the internals on the 420a will not support more then 8-10 psi of boost without upgraded internals.

Also, if you plan on turboing a gs, remember that you will have to increas your fuel flow by getting a larger in tank pump. All the aftermarket kits already come with everything you need for a direct bolt on. Including all electronics. You'll prob want to upgrade your ignition and plugs too. You'd probably be best just getting the gst and buying an upgrade turbo

All stock turbo cars as far as I know come with internal wastegates. Externals are not only very loud, but also illegal. Not that either of those reason stop us from enventually upgrading to one

Ok...i'm looking for about 400 hp (or more cuz we are tuners).How hard is it and what do i have to do to make a gst an exteranl wastegate...or would it not be worth it to change it?It sounds like i'm going to get a gst then.To get 400 hp will i have to get my engine internals built up?I have the feb 04 issue of Sport Compart Car...and this guy has a 95 gsx.He had a turbonetics T66 turbo, custom manifold and all...but i dont see the external gate...do the T66's have an internal one?Oh yea...i want to run about 14.7 (1 bar) of boost to get 400 hp...that means i need 200 with out the turbo...what can i do to do that?

before I give my imput
why do you persist on external wastegate and want to run 14psi only?

Cuz i want to run it at 14.7 psi all the time...i dont want to run 20 psi or more all the time like some ppl do.The more hp i get with out the turbo the more power i can get from the turbo with lower psi and even higher if i want to turn it up.External wastegate ...i dont know...i have seen some turbo thats have an internal gate and the gate doesn't open.I have talked to some ppl that have said that external is better, it my be more money for one but they work alot better.I like the may they work to.But i dont know if it really matters.

you really got to study up on this stuff... you are thinking in honda terms, where 1 bar is a ton of boost, and you need 370 injectors to upgrade to a turbo... this is stock boost for the dsm. some guy's are running like 25psi on some turbo's that are on daily drivers... you want to adjust it get an electronic boost controller. and 400 hp on a fwd is alot of power to 2 wheels, unless you want to get into LSD's and such. think of getting a GSX if you want tons of power. also there are kits that come with an external exaust mani... check hahn race craft for some enlightening info

I was curious of this my self. I recently bought a 1999 although i thought it was a 98 GSX.

Great car, but im never happy with the stock for long.
I was looking for a turbo kit that offered an external wastegate. Who offeres such kits? Links plz.

Thanks

greatly appreciated

14 psi is stock for a 2g You wont make more powr at the same boost with a larger turbo unless the curret turbo is out of its efficiency range, and even the stock turob isnt doing too bad at 14 psi You need more flow to make more power. You need to roughly double your flow to hit 400 hp. It will be damn near impossible at less than 22-25 psi without going to a pjhysically larger motor (2.4, 2.3 stroker, etc) even with all of the airflow enhancing mods such as cams and intake manifold. A massive FMIC is in order as well and will improce flow at a given pressure.

Im thinking of a max boost level of 35psi. At that level i could push the 500 mark could i not? With an upgraded fuel system, intercoler, BOV, engine electronics, cams, and such.

[kjewer1]

you better be looking for 600 hp if youplan to run 35 psi. Head gasket sealing will be an issue. Chad on the POSr site did 500 whp at 30-31 psi. Thats what you should be expecting.

[89Turbo944]

O i do not plan to run that more than once or twice. Just for the hp numbers. But at 35-36psi i could push 600hp on a 20g?
