GSX build. Shooting for 500hp! Need advice

[ShaggyGSX]

Hello I'm pretty new here to dsmtuners.
I have a 1997 eclipse gsx. Pretty stock for now. Has exhaust, walbro 255 rewired, small intercooler, and a cold air intake.. I've been running this setup for a couple years now and I'm wanting to do a small build.
I'm going to shoot for 500hp. I've got a couple friends helping me, they have 700+hp evos. But we've been doing some research into what I should get and I am just looking for other people opinions.

I'm really wanting to do a top mount manifold..more for the looks. I've always liked them but little worried about space and intercooler kits that can run to a top mount.

Think I'm going with a
Gt35r
1000+cc injectors and fpr
Electronic boost controller
Short route fmic
Dsmlinkv3

I think that's it..but I'm looking for any and all advice I could get. It's most likely going to be run on 93oct. E85 is hard to find where I'm at.
Thank you all in advance! Have a good day!

Sounds like a fun gameplan.I tend to see a lot of top-mount manifolds for sale so I'm sure you can hold out to get one. Also, if you are going gt35r the exhaust hotside could be important in achieving your goal of 500hp on 93. Good-looking car.

I would like to advice against any manifold that robs you of room, for your cooling, fans, rad, ect.....

If you do, there will be allot of work to keep temps down. Shrouds, ducting, heat blanket, tape ect......

Just something to consider, I envy those with the oem style manifold, nice and compact...

@Vegas smith
Is the hots idea restrictive? What would you recommend?

@miliman13
I planned on wrapping it with heat wrap. I found a guy that can custom make them and mock it up the way I want to route everything. Lol

When I bought my gt35r (that I never used) I concluded that there were around 3 hotsides for the gt35r (I'm sure there are technically more): the 0.63, 0.82 and divided t4 1.06? Basically, from what I've read the larger the housing the more lag but the better pump gas capability and overall airflow. I never used that turbo so I can't recommend something.
