chances are you won't get a downpipe with your clip if you're getting a clip. So that'd be a good idea to have.

The electric fans aren't really necessary if you're on a budget. I'm using my mechanical fan and it's more than sufficient especially with my koyo 2 core radiator.

The battery might be a good idea, but it might be a better idea to move it to the rear, better weight distribution, cleaner engine bay, and also cheaper.

with the t28, you might want to consider upgrading the wastegate actuator so you can take advantage of the t28's greater potential and the fuel injectors.

Do you have a new fuel pump? My initial guess was you were gonna turn up the boost pretty soon after getting the SR in and that'd be probably a pretty safe upgrade to make.

Looked into a thermostat? It might be clustered in with your misc. swap parts but I've always changed the thermo's with a tested new one with every one of my 3 swaps completed after the first one had a bad thermo.

The clutch might be a better buy if you go with something with more clamping force. It's a PITA to do the clutch stuff on these s chassis cars. You may want something more than just a stage 1, otherwise you may be in for a new clutch sometime soon as you'll see that the stage 1 doesn't give you much leeway later on as your ambitions increase the power output of the motor.

bov? might want one of these

boost controller?

One word.......

Intercooler.

As in front mount. You will get more hp with that nice t28 if you get one.

And the fuel pump is a MUST.

And get a downpipe.

I already have a greddy vspl intercoolerenjuku hot pipegreddy type s bov----------

so not on the list....

-NISMO cold temp thermostat: for getting cooler, naturally...-down pipe? isn't it only a 5~10hp gain? maybe I simply ignorant as to what exactly it does... does it replace the catalyst convertor?-fuel pump.. walbro 255 fuel pump? on ebay it is about 100$ shipped, but I see a LT/HR and LPH, I don't know the difference...?-injectors, do I need injector to run safe boost at 12lb? man those nismo injectors are pretty expensive... -wastegate actuator, when you say upgrade... do you mean that I shoudl upgrade to adjustable ones?-clutch... I had an ACT clutch with 6 puck springless disc and man I hated my integra because I have to focus on driving so much. What alternative do you suggest that will at least have a stock feeling to it?

------

keep in mind that this is a daily driver and I don't want to have to SUFFER in any way, especially when I get so tired from school and work, let me know, thanks!

I dont think the nismo thermo's a good idea. mainly because it'll keep your motor too cold for daily driving and it'll jack your mileage.

Downpipe fits from turbo extension (little elbow thing that hangs off the back of the turbo) and connects it to the cat. You'll need this, most clips let alone motor sets do not come with this part.

walbro's are decent and cheap. can't mess with the bang for the buck.

You don't have to get nismo injectors. to run 12 psi, you'd be edging near maxing out your injectors. If you plan on running 12 psi daily, get the bigger injectors.

the adjustable one is fine. The HKS one is a pretty good buy. bout 100 bucks gets you something that's pretty adjustable granted you've a vac pressure gauge and or a vac pump or something to measure how much boost you're running.

The ACT springless 6 puck, if you're gonna get a more streetable clutch, get the one with the sprung hub. You can try Nismo's copper clutch, but those are way expensive. I would get the 6 puck ACT with the sprung hub or look at some more of the exedy lineup. Unless you've got alot more money to spend in which case you can look into the multi-plate clutches like ORC, OS Giken, HKS, Blitz, Nismo, or even Cusco.

what happens when the injector can't handle that amount of boost? premature detonation?

in the event that injector is not giving enough power... then what?

can you tell me what you meant by nismo thermostat runs engine too cold? isn't colder better? especially during long drives on freeway? and what you mean it'll jack the milage?

it'll run lean if you don't have enough fuel coming out of the injectors. lean == detonation.

the nismo thermo is tuned to open at a colder operating temperature, therefor, keeping the overall engine colder. i don't see why it's a bad idea for a car that will be seeing track time, but i would stick with stock if this is a daily driver. the koyo and the fans will be plenty enough to keep the engine temps in control.

I don't see exhaust on your list. Do you already have a three inch, mandrel bent exhaust? If not, get one. Otherwise, you're not going to be making any power. When I did my swap, I didn't get an exhaust. It was slower than the KA until I put the exhaust on there.

so exedy stage 2 clutch is okay? am I going to hate my car for it? I wnat to be able to drive slow and don't want to do that precise clutch engagement at all times....

what about injectors? what are some decent injectors to buy? do I need like 550cc?

as for exhaust, I want something that looks stock, I am thinking about doing custom 3 inch piping, spray with high temp anti rust paint or something + original muffler, haha what you think?

I think that your original muffler is going to be a big bottleneck. If you want something stock, find a y-pipe that you can vent before the muffler.

You dont need other injectors with your setup...............stock is fine.

If you can afford it.........get the exhaust.
