i wanting to do a turbo swap with a jspec engine. im looking for 400 to 500hp after all is said and done. i know of companies like greddy and hks make upgraded turbo kits and intercooler kits but im not sure which would be the best for the money. also if their are some lil tips for doing this project please let me know. any help will be appreciated. thanks

 

I'd hop on over to the single turbo section and look around a bit. I know those guys are turbo aficionados.

 

i hope you have at least $10,000 to spend...

 

400-500?? thats a lot of power, sir. I would read up in the standalone forum, single turbo forum-- actually, I would read everything you can.

 

You might want to do swap first and then you can slowly move parts over to do the power mods. Hybrid turbo, new ecu, fuel mods etc.

Also you may want to rebuild the engine, as the JDMs seem to be hit and miss. Besides then you can do a big *** brideport.

check out c.a.p.a performance's kit for the s4/s5. this is what i'm planning on after the new microtech is installed, aswell as a v mount cooler.

Considering he's in Kansas, ordering from an Australian company may be a little unlrealistic...

If you want to make 400HP, then A-Spec sells a GT35R kit that will do the job nicely and provide good turbo response on stock ports:

Here's SpeedMachine's version:

If you want to make 500HP, then they also carry the GT40R in kit form:

And from SpeedMachine:

To run the GT40R properly you'll need a ported engine. I'd recommend a bridgeport to keep lag under control.

Keep in mind that either of these turbos mean that you need a full fuel system upgrade (injectors, pump, standalone), intercooler upgrade, full exhaust and all the little miscellaneous bits (lines, fittings, TUNING, gauges, clutch, TIRES, etc.) that go along.

 

^this is what i did. i have a t04s/s4na. figured the na ports would do me better with the longer timing.

i read everything. infact, i spent almost a year on here every night for several hours before i even bought my car. and then i spent a few more months just studying the standalone stuff. it paid off. but was still a bitch at times.

 

actually i would start researching other peoples projects to see what all they did, that way you have an idea about what to search around for as far as info goes. check the singles area and other like places for these projects. this really helped me realize how far i was willing to go. there will probably need to be some custom fab stuff you will run into as well. i hadnt really allowed for this untill the time came. but thats more if you are on a budget, which i was. but doing everything my self, i have spent nearly 4.5k on driveline and engine, fabbing several things from aluminum as far as intercooler, oil cooler, rad, efan, etc... goes. i went with a vmount setup that took some planning and a lot of fitment. trial and error bud.

 

alright thanks alot. i have all the time to save the money and all the time to do it. im leaveing for the navy in 2 months so ill have the time wont be at home. thanks again
