Hey all, I am planning on getting a gs-r relatively soon. I am very mechanically inclined, and currently own a dsm (hense the very mechanically inclined). I have a few questions about this car. The search function today is not working for me, so I will try and keep my questions short.

I plan on boosting the car eventually (around summer). I would like to make around 280-300 whp. Something reliable. I like kits. I have fabbed up my own turbo settup on my dsm, and it was a pain in the ***. Unless people make xx I/C piping to fit xx turbo on a b-series motor. Which turbo settup would you recommend for my goals? I don't care about 1/4 times, because I have another car that takes care of that. I am thinking something like screw around car/highway king. Kit doesn't have to be legal.

To start out, I want to get an intake manifold, catback, do all the maintenence upgrade like plugwires, plugs, ect. ect. Which mods would you add before boosting at moderate levels? Aside from the obvious ones.

Do pullies benefit the car at all?

Some good cams? I have read about the ctr's. How much of a gain do they add? Good with boost? Raise the rev limiter? (I like highrevving cars).

And finally... How much whp do these things put down in stock form?


Thanks.


Also, I will be yanking out my safc and egt gauge. Are these really needed to tune it? I suppse I will get it tuned via hondata, ems, or uber, and wideband.

 

I like your start out point, sounds like the right route to me, maintenence before mods. From what I hear you get much better gains from fabbing your own turbo than buying a kit for the same price or a little more, but if you don't want to deal with it, the kits work nicely too.

Underdrive pulleys benefit a little, but nothing great, about the same as other mods in the same price range.

And whp gsr's put down usually between 140-145 stock, some go to 150 stock, and just fyi they typically pull 170 bhp.

If you get hondata you definately don't need the s-afc, but why not keep it until you get the hondata.

 

Yes, they do have people that make xx i/c piping for xx turbo on a b-series. A lot of people will build up a b20 or b18b (GS-R is B18C1 for USDM and B18C for JDM) bottom end (CRVTEC or LSVTEC respectively) and sleeve it, then add boost. But for the hp range you are looking for, this probably won't be necessary...although it may be more reliable. You can build your B18C1 for boost too though. Sleeving and some low compression pistons will do the trick.

As far as kits go...rev-hard and Drag seem to make some of the most popular kits as they offer quite a bit with them. Lately though, I see a lot of people fab their own kits using parts from the above companies, and adding their own choice of parts for fuel, i/c, turbo, manifold, wastegate, engine management, etc. I think it's cheaper to fab your own.

Start with the maintenance...then setup your motor for the boost. I would advise a 3" catback for max-power, but lots of people us 2.5" and are just fine. For intake manifold choice, definitely get the JG Edelbrock manifold. It is meant for boost as the runners on it are fatter than say the Skunk 2, which is designed after the ITR manifold. If you want serious tuneability, then you can get Hondata S200 w/ boost and tune the **** out of it. I also advise getting lower compression pistons at the bare minimum if you want to boost anywhere over 10psi. I have heard of people that are well tuned going to 14psi, but that is seriously going to limit the motors life. One lean run moment, and your done. A lot of people run the LS (B18A or B and B20) motors because they have lower compression stock.

Pullies don't do much...just strip the A/C and P/S out.

CTR cams are all motor cams. Skunk 2 has some good cams for boost...some people use JUN cams...I'm an all motor guy, so I would be better off w/ the CTR's.

You should see about 140ish at the least with the GS-R motor. Some put down around 150 like ckyguy said.

If you are going to get Hondata, then safc will be useless. The EGT would be a good thing to keep though.

If you want to try something new since you have already had boost...try the all motor thing out. Stock-like driveability, stock or sometimes better gas mileage, and a very useable powerband...just my 2 cents.

 

The more I think about it... The more I like the idea about building an all motor car. Is 200whp achievable? I suppose the list of mods now includes some form of intake, bigger T/B, good intake manifold (the blox looks interesting), good valvetrain, header, and catback. I would not want to tap into the block just yet, for the sake of money. I will probably do this, and build a good bottom end with lower compression pistons.

Is Vtec controller a good tuning device? Easily making 200+ to the wheels?
