I'm currently running a jrsc on my 19k mile R at 6lbs. It's putting down 200whp and is a fun car to drive. But I was thinking today that I'm planning on keeping it for a long time and at some point (maybe sooner then later), I may want to change things up. I've only had one turbo vehicle and it was an STI so it wasn't an aftermarket setup. I don't know much about putting together an aftermarket turbo. I'm curious what I would need to purchase to switch from the SC and what costs would be involved. I already have a 255, RC440's and s300 so the support is there already. I wouldn't want anything crazy. I don't drag it but do take it in the twistys. It's not daily driven but I want something reliable that I don't have to fool with constantly and would give me 300 whp +/-. Then I started thinking about a NA build. Would 300 hp be feasible going N/A? Then again, I don't know if I could bring myself to tear apart an original 19k mile motor lol. Thoughts?

 

Leave that damn R alone

Buy one w/ 90k and mod it ...lol

 

Don't tear apart an original 19k ITR motor. Take it out of the car and build something else and put it in, I wouldn't touch the stock motor.

 

and i wouldnt have a problem turboing the stock motor... but i trust my tuner that much.


300whp NA isnt cost effective, or streetable im sure.
300whp turbo is a walk in the park, even on a stock motor.

 

Very true. That is such low mileage.

 

weren't you just raving to everyone how **** supercharged R's were?

 

i have a boosted ITR, but damb whats with all these boosted questions.
isnt there a link to Force Induction on this site?
in 3 min the top 3 post were about boost, who would of thought....

 

It's because this place has gone to ****

 

I wasn't raving. I was just saying that there are some pros to the blower, just as there are pros to the turbo. I tend to tire of cars quickly. I've had probably 7-8 in the past 2 years. The point is that I am definitely keeping my R. It's the first car that I've owned (except the NSX) that I really feel connected to and I was thinking about how there're so many things that I could do with her to keep things fresh. I'm not saying I'm doing them now, but down the line,it's nice to know that those options exist. I love my SC for now and will probably move up to 8lbs soon. But there's nothing wrong with doing research and comparing setups. Not everyone is into "keeping it stock". My NSX was stock. It was an 02 with 800 miles on it. I couldn't bring myself to do anything to her because I felt it would ruin the value. Well, that's not much fun so I sold her to a collector and moved onto something I could mod.

 

It's your car, do whatever suits you best. For me, that would be NA. For you, maybe that's turbo. I think you're the only one who can answer to what your goals with the car are, and how much time, money and frustration you want to put into a car.

 

I know it is your ride, but only 19,000 miles definitely holds some collectibility (despite already being supercharged) in my book.

 

Got ya, well if i were you (given the fact you've had an NSX you shouldn't have a money issue haha) I would just build an LS/VTEC for boost and just do an even swap out. That way if you ever want to turn back to N/A you still have a minty 19,000 mile c5 waiting for you.

 

^ not a bad idea, if you already have the original drivetrain it would be a shame to kick a rod through the block.

 

i also ran a JRSC on my itr too. i recently changed to a turbo setup.

if your goals are 300hp and you have hondata s300, you can just run boost by gear to help with traction issues if you like to auto X and take it to the track.

i mean with my JRSC, i had 260whp with methanol injection on 1000cc injectors but decided i wanted more since i was not auto X my car.

overall its your car but if you do go boost, you can always go boost by gear. for example im on stock block and head boosting my car.

1st and 2nd gear 10lbs
3rd gear 10lbs-14lbs (i boost 14lbs towards the end of my gear)
4th and 5th gear 17lbs

oh and in question to NA...i do not think 300whp is possible without a good amount of money. easiest and cheapest way is to boost it. you can get a small turbo with little to no lag.

 

So noone really answered my question lol. If I did want to make the switch, what would it entail? Just an I/C, a turbo, and some plumbing to connect it all?

 

your going to need a tune and all that too I would assume. I have 17k on my motor and all of that and I am already wanting to boost it. I looked into superchargers but a turbo there are so many more options and its easier to make more power. I just hate the fact that there are so many boosted Honda's the R's motor wont shine as much like it did in NA form. The stock motor runs pretty good and its NA. The facial expression when your walking someone and they looked confused because they dont hear a turbo is priceless. I want about 250 - 280WHP out of my R. 300WHP I think scares me because your getting to that point where for reliability you should probably sleeve it and what not.

 

I would honestly say you may be better off just starting from scratch and concentrating on your turbo build.

Figure out your power goal, research different turbo's (not just size, flow characteristics as well) and go from there, as you start to hammer out a plan things will fall into place such as what size injectors you will need.
