Ok so here it is. I got a 92 hatch si, already have a ls swap and other add on's. (jg-tb, fuel rail, pressure reg, cold air, custom exhaust w/no cat, clutch, tk: blues coilovers, and a few other things... Has been like this for like 3 years now, and I love it.. But lately I've gotten a wild hair up my a$$, and what to go bigger and badder... Ls/vtec...ls/t...or fully built gsr setup... And It just so happens the other day I walk into the repair shop next to mine and there it was. A B18C, motor, head,tranny I think with lsd, idk gotta check, axles, shift linkage, wiring harness, the whole shabang... But the block has a hole in the side of it so this still leaves the door open, use that head on my block, or find a new c-block and do a full build, "new crank, rods, pistons, all new head internals, the whole thing all new and big dog s;&t" and stay n/a oh and I almost forgot the guy that owns the shop were my future baby awaits me. LOL is given me everything he has for $200 bucks which can't be beat no matter the condition.. So any suggestions, or input on what my next move should be, would be great, this is gonna be a long, year or so project that I will take my time on and do right, whichever way I go, and it is and will be a daily driver..

 

How much money are you looking to spend total? If you have a solid LS motor already I would just boost it. Even at like 8psi which would be safe for everyday use, you would have a pretty quick daily driver...

 

Money is an issue in one way, that's why I plan on doing this over an extended time like a year or so. You know a part here and a part there when I can, so I really don't care what the final cost is, cus I'm not doing it this weekend ya know.. I did think about turbo, but I'm kinda hung on the thrill of beatin up on other cars with a n/a built 4cyl. I just find alot of fun in that.

 

N/A performance is attractive but it will be a serious undertaking on a b series... At that point you would have to get a GSR motor or go LS/VTEC or something like that. All of this would cost significantly more than boosting your LS motor. Boosting the LS motor in my opinion is the most cost effective option for you. You will out perform a N/A motor with the same amount of money invested...period... If you are bent on going N/A look into LS/Vtec there are plenty of threads on Honda-Tech about it. K swaps are also very solid N/A performers but they are also very expensive...

 

Boost your LS.

 

as written in my first post im getting a B18C, tranny, wiring harness, and axles for $200.00, only downfall is block has a hole in it...but i can pickup another c block from somewhere

 

With the money you are going to spend on getting a new block, plus all of the little parts you will need that might be different between LS motors and GSR motors, plus labor (even if you are doing it yourself it is worth something) you will be out roughly half the price of a turbo kit...

Even if you get the GSR motor running smoothly, and do all of the basic bolt-ons, you will have spent enough to buy a turbo kit and the GSR will still under-perform compared to the LS...

If you are bent on going with the GSR motor then by all means do it. You are going to be spending more money, with worse results...

 

Boost

 

Ok somany people are saying boost, and this is going to be a lenghty project so I don't really care if the cost is $1400.00 in the end, that being said... What are yall's outakes on a properly built low compression turbo setup on the gsr I'm getting for only 200... And I mean proper, all new rods,crank,pistons, sleeved block etc...built head, good tune,and ecu.... I have seen sick hp#'s on these setups and ones that can be tuned down for a daily driver and tuned up for track fun....yea mabe crazy, but sittin around 300-350 on the street and the abilty to be tuned up to around 550+ on c15 at the track sounds like my kinda fun in a hatch.... Just add wings and ur ready for take off. LOL.... Got a buddy of mine with a 8-900 hp mustang on a 350 shot of spray it's sick but wanna hang with him or hang him up at the track then drive it to work the next day, why?? Cus I can...yes I know it would be lotttttttsssss on money, but you can't take it to the grave so what the hell, why not, but like I said ur opinions on a sick gsr-t I'm open to whatever, just throwin darts for now, u know....

 

At this point I would take your question over to the forced induction forum. Your question at this point is going out of the scope of my knowledge. However, if you are going for a low compression GSR build the advantages over the LS motor will be negligible...

Since money is of no concern, why not go with a LS/Vtec setup. You get the best of both worlds, the extra displacement and torque of the LS motor, with the good flowing head and vtec of the GSR head. People have made sick numbers with turboed LS/Vtec setups. Then you don't have to buy a new block you can just use your LS block.

Plus you could run a N/A LS/Vtec setup for a while with decent performance until you had the money to buy all of your turbo stuff...

 

high compression turbo, fuel with methanol (you can run 15:1 CR in naturally aspirated form) and with the turbo use water injection to keep detonation aside.

snow performance offers stuff like that for the diesel guys, and why wouldn't it work on a turbo civic? Just need a smaller sprayer.

 

That doesn't sound like a very streetable setup...
