what difference would i notice if i was to put a t3/t4 turbo in place of my stock s13 sr20det's turbo? could i get more power out of the t3,or would it be comparably the same? the reason i ask this question is becouse i see the t3/t3's on ebay goin for dirt cheap.if it is a good investment what else would i nees to purchase/modify ??

You'd notice it spooling faster and earlyer. And you would get maybe 10 rwhp from it just because it would be more profecient.You would need to get a top mount turbo manifold if the flange is bigger then a T28 flange. You'd also need a waste gate if it doesent have a internal one (one thats built into it) And you would also need a custom hotpipe and maybe a BOV.It would be a really pointless investmen because if you dont got the cash for other upgrades like fuel and such you wont get the motor to the turbos potental. (no sence in haveing a turbo that can support 400 rwhp if you dont have to other nessasary equiptment to handdle it.So your T25 will work just fine untill you are ready to upgrade the fuel. Also the turbos on e-bay would probaly not be to good. BTW The bigger the inlet size the faster and more air it will move (in most cases)

Any garage really, its just piping and welding a bov on. And same with a custom down pipe noting to it. Well it depends on what type you want tubeulor,log or cast iron. Make sure you get good qualtiy metal if its a tubeulor manifold , anything highter then 304 will work really well. and be more resistant to cracking. Also there are two types of tubeulaor manifolds mandrel bent (bending the pipes with mashienes) or they weld individual pices togeather to make it. If you want a REALLY high quality manifold try HKS , or if thats too pricey try one of the sponcers i am sure they'll have a great deal for you, cause your a NICO member but if thats even too pricey SSAUTOCHROME makes a top mount manifold for about $330 USD they are not bad manifolds i have one and its great. Alot of people say trash about them, and it is true some of their manifolds will crack but not all i guess it's just the luck of the draw I hope this has helped you

for injectors, you can use the 550cc from a 3rd gen RX-7. Thats what i did and it works fine. But you will need something to help control them (SAFC or custom ECU). I got my injectors for $120. RX-7 guys hate them because theyre stock and dont give much power for them.
