Well heres the deal, I have been reading a lot on these motors and everyone seams to have their own thoughts. So i guess it wouldnt hurt to hear a little more. Ok well i want to build a Ls/vtec or a GSR to be able to produce 350+ whp. Now should I get the ls/vtec and get new crank, rods and pistons, rings and boar it our a little and put the vtec head secured with ARP studs. The head equiped with new cams, cam gears, 3 angle valve job, new springs and retainers. Or get the gsr and just rebuild the head. Kepp in mind that i want to slap on a t3/t04e turbo and boost a bar or so, maybe a little more. of course hondata s200 tune, 550cc injectors, 6 puck racing clutch, c/m flywheel, LSD in the ls tranny.......ok well im done rambling on. Which setup would you do?

 

I would talk to the people in your area and see which they have built more of and go that way. You don't want a guy building an LS/VTEC that has never done it and vise versa. I would also say which ever one you have the money to throw into it. GSR it more pricey than LS/VTEC. GSR has the block girdle which is nice in a turbo application to keep the bottom end solid. It is really going to be your call in the end.

 

CRX Toad

Say the shop i want to go to has done both and has work to show for it. Also money isnt really an issue but i dont want to go too cheap or way to expensive.


How much do you think this setup would cost?.....Anyone

 

both will do it well
I tend to lean to lsvtec now myself lil bigger and you can run gsr head if you want

corollagts33 I tend to lean on Ace with this one. However I would use a B16 head or ITR head. The ports are a little better on those. The GSR has kind of squarish ports.

 

350hp you can get out of a built B16

and you want S300 hondata now

oh and you better sleeve it

 

well to be honest. judging from how you typed things out. you dont know much about honda motors and boost setups. period.

you dont need a new crank. you wil DEF need forged rods and pistons as well as a sleeved block for +350whp. IMO why do you want so much power? assumin this is a daily driver, you gonna be rollin around town on slicks all the time? 350whp will only do u good on the hwy. if you wanna do 300whp. you can get that safely on a stock gsr with a good tune on hondata. I would say you do that. or if you have the cash, build the motor,by then youll be able to make over 450whp with the proper turbo setup , which , once again is pointless cuz the tires will just spin.

just go for 280-300whp. thats all you really need .

 

6 puck clutch= not daily driver

There is a GSR down here in a ek hatch by where I live In Tacoma. it belongs to a guy named ZOL, He works at a shop called speedline you should get online and look up the shop, google it or something and call him. I belive he has 300+ whp on stock GSR bottom end.

I certainly hope that was sarcasm. MMsportsRexSi (Kaan) knows quite a bit about Honda engines. Hence why he can be found tech'ing Honda Challenge, Spec Miata, American Iron, ETC for NASA and frequently around NOVA shops. I would have to agree that for boost to put in some sleeves in there for added security.

No matter what you are doing either LS/VTEC or GSR you are heading the right direction. If this is going to be a weekend fun car, everything you are saying sounds good. If this is going to be a DD you may want to rethink the 6 puck but I personally say there is not to much HP for the street just don't be an idiot and respect what you have.

 

Hey guys thanks for all of the replys. This will not be a daily driver, just a weekend car. But once again thanks for all of your imput. Keep them coming.

 

Anyone elese?

Stock sleeves are known to withstand 500+whp easy. The guy doesnt have to run on high boost all the way, he can run around town with a conservative low boost tune. IMO i would build a ls-v with valvetrain and type R cams, forged internalls with a edlebrock intake mani. Porting isnt necessary to reach 350whp. The turbo set-up is what you should really be doing research on.

hahha. yea right buddy. i mean,yea you can make high HP with stock sleeves. but were talkin daily driver here. how long will it last at that HP level. and DUH he wont run around town on high boost, but then again what the hell was the damn point of turnin up the boost on the dyno and gettin 350whp, then roll around town 280whp?!?! just to look cool with a damn dyno sheet? gimme a break. and yea, he can turn it up at the track , oh wow. then he goes home and the boost goes down again .

 

gsr and pistons will make 350hp. get yourself a peakboost kit....easiest way to 300hp it seems......i dontk now how many gsr/peakboost cars weve tuned now.

I would start with as much displacement as possible, a B20 CRV-TEC. Like some others have said, sleeve it, get forged pistons and rods, and have a shop balance everything.

 

ya i think b20vtec is the way to go.

 

B20's with stock sleeves wont last long with a turbo setup. I've read of people saying how the stock B20 sleeves will crack, it's just a matter of how long till that happens.

I would personally get a GSR block and swap an LS crank in it and get some pistons and rods. You can make 350 WHP on the stock bore no problems, but if you want you can sleeve it out to 82, 83 or 84mm. But even with stock sleeves you shouldn't have to worry about cracking them, unless you have a crappy tuner.

As far as headwork goes, you dont really need to do any headwork, but it doesn't hurt. You could try to find an ITR head and just keep it stock. If you haven;t already bought a head, the ITR is the one you should get cause the ITR cams will make more power plus you have the ITR valvesprings to go along with it.

You'll probably want something bigger then a T3/T04E though. Think about getting something bigger like an SC6152E, T3/T61, or T3/60-1. Or if you dont mind spending a little more you could look into a GT3071R, GT30R or GT35R. For EMS you can stick with the S200 or get the S300, but for injectors you should probably get some 750's or maybe just say screw it and go with 1000cc's.

 

Once again thanks for everything guys.

BlueShadow i have been leaning towards the setup that you suggested.

Going with the GSR, LS crank, pistons, rods, ITR head,650-750cc injectors, larger turbo and a good EMS s200/s300

sounds good man. keep us posted

 

To be honest, the way to get the best of both worlds is with nitrous. Put a GSR with the ITR head on it and build the internals and the fuel system and you can pop a good 150 shot of nitrous to it safely. YAY! If you research, youll find that nitrous is completely safe, so long as it is used correctly. Whereas nitrous slowly (or quickly) wears down your motor. Im looking for longevity, and practicality. I personally would not go with the LS crank because of the longer stroke, it throws off the rod/stroke ratio that isnt quite what it should be in the first place with a GSR. Whereas with a b16... you can go rev crazy. Droooool.... anyways, you can also end up having a little valve to piston make out session. bye bye valves. youll reach that 8200 rpm mark and it will just stretch too much. Look into nitrous, its SO much cheaper than turbo - you may find it in your best interest. Oh, you can use the LS crank if you find LS/Vtec pistons. The valve reliefs on a gsr/itr/b16 wont be deep enough for that extra stretch.
Im sure ill be banished to hell for mentioning nitrous. Some people say its too easy, i say its too hard to ignore the facts of its total superiority to turbo. The money you spend on a turbo kit can be used to build the motor up and down. Then it can handle all that power, not like you werent going to build it for turbo anyways. I dont check this much.... but if you have questions, email me at jlantic@yahoo.com - i will keep you posted on my CRX build that is almost done with my poor mans type r nitrous (350 whp is the aim). Have fun, and remember... hours of research is better than hours of working to pay for a broken motor.

 

IMO if i were to ever build another motor, i would definately go with a gsr. You get the girdle, and you use better bearings. Don't get me wrong, you can always add a girdle to a ls block and notch the rods for the gsr bearings, but when your only making 300-350whp it's not really worth it. Just go with a gsr, you'll be happier in the long run.

 

6 puck = fine as a daily driver.... my cars not literaly daily driven but its driven on the street 3 to 4 times a week and in alot of traffic at times and its fine.
