Hi guys, I wanna put a turbo for my 4g64, I'm thinking about gt2871r or td05hr 16G, I want a power around 300hp and the minimum possible lag, what do you think guys?thx!!

I think no unless the engine has been built for a turbocharger.

Right, but I just rebuild the engine, my 4g64 is 7 bolt, the last year buy a head 4g63 for swap, I have a rod and piston forged, bearing main and rod oem new, head ported, custom aluminium intake manifold, trottle body 80mm, all piping 3" intercooler with intercooler one side 3" outlet, cam gears adjusts, turbo manifold flange T3, but I don't know what turbo or injectors I must put perfect for my...I need experiencies...hehehe

In that case the Gt2871R.

Thx and the size injectors? Oem gst?

I was gonna say, don't! I turbocharged the 4g64 in my 3rd gen Eclipse GS. Blew the engine three times before getting rid of it. Just get a turbocharged car. It will cost about the same in the long run. Turbocharging and supporting mods isn't cheap. But if it's built for it, have fun!

Hi Turbo2g, thx for your experience, but in spain have ten spyder 2g and Its very exclusive this model spyder, so I think that is best option have engine 2.4 that 2.0, also I have a nissan 180sx stage 3 for drift and 300ZX twin turbo with mods yet, I wanna swap turbo because is more fun hehehe, I'm decided buy gt2871r and I hope lucky hahaha.

Go with a set of 680cc if your running pump and dont plan on high boost.

I second the 680cc injectors, I would strongly consider pairing them with an aftermarket beefier pump.

So injectors around 600cc and fuel pump type walbro 255lph? And the head gasket I don't know what use...gasket of galant gdi dohc or evo dsm cometic, but I read that cometic is shit?

Your injector cc/min should be calculated based on your power goals not your fuel pump. I am in favor of buying large cc hi-z injectors once instead of upgrading later. Injector Dynamics has some great info and calculators: http://injectordynamics.com/the-library/
Pick a fuel pump that will keep up with your needs too. A Walbro 400 is almost the same price as a 255 and I doubt you will nedd more than 400lph. Only use a MLS gasket if you have perfect mating surfaces on the head and block. Otherwise a Cometic (or MLS OEM) head gasket will suck.

Thx for the help DJRace, but the injector low or high impedance? high is very hard to find, I see that the people buy low impedance and put box resistor, what do you think? I can't spend much money, I wanna onlye have spyder with turbo same version gst but with any more power hehehe

I mean high impedance. Z means impedance. It is the easy way to express the ohm symbol. Why are they hard to find? Here are some excellent injectors: http://injectordynamics.com/injectors/id2000/
It may be cheaper to get low z injectors and a driver depending on your choices.
