Plans for new motor.

[fsteclipsegst]

Hey guys whats going on? well im here for a little bit of advice. Im mostly a DSM guy but i've been experimenting with hondas for a little while now. About a week ago i bought a CRX for 150 bucks. its not in the best of shape but that is getting taken cared of in a body shop(while have pics of build in another thread soon). But the shell is the least of the problems the main questions are for the motor build.

I picked up a GSR from some guy in Indiana for $300.00!!! all its missing is the throttle body! they did'nt know the posibilities of the motor! the motor is from a 4 door GSR and it had 86,000 on the clock. i would of gotten the tranny too but the bell housing was cracked from the crash (reason why he was selling the motor and parting out the car).

So far i have heard nothing but good things about GSR turbo. but before I boost it im going to do some work to the motor, I was thinking somthing like this...

• Dual layer head gasket
• ARP head studs
• CTR cams
• Stock or maybe aftermarket throttle body
• Blox manifold
• Replace timing belt and water pump.
• Get the head and block inspected by a machine shop

i've herd that 10 PSI is a good a mount on a Gsr. but if i were to lower the compresion whats the max i should go?

and here is what i have questions about.

Is 10 PSI to much for the stock motor/compresion?

Should i just go ahead and do pistons(to lower compresion)? If so which ones?

What turbo would be a good match with this motor?

What tranny would be better Gsr or B16( i can get it for 100 bucks)

What clutch would you recomend.

any help would be greatly appreciated!

Ok, first off DO NOT do a dual layer head gasket. That is the wrong way of lowering compresion, and on that GSR it's not neccesary to lower the compresion either; just a good tune. PSI is the most misconceived use for measurment. What you should really focus on is what HP goals do you wanna reach? And what is your budget. Sounds like you want to do stock interenals, proably looking at 250-310 HP Max. I'd recommend a typical t3/t4 turbo and some sort of engine management(hondata, uberdata, what ever). Is this car a DD? If so I wouldn't recommend the GSR tranny unless you don't mind 4500 rpms at 70 mph. Other wise it's a great tranny, doulbe cone sycros, built to take hell. As for a clutch, if you don't mind the car jettering when you take off. A 6 or 8 puck is great! Or you could get a Double layered one. It really depnds on your budget. You need to do your research, lots and lots,ect... pgmfi.org, honda-tech.com, google.com.

i was not going to do a dual layer to lower the compression i was doing it for the boost. i figured since on DSM's its always a good thing to have a dual layer headgasket it might be alright on hondas. i was also reading that the OEM headgasket is a good thing to use. as for horse power, i was thinking about maybe 300-350HP. for the past few hours ( work is really slow right now) i been reading and this is wat i have come up with.

bore it a little
CP pistons running 9:1
eagle rods
balance the crank and all the Hardware.
better oil pump
a mild P&P
maybe valve's, valve seals, valves springs, and retainers

also, i will be going with a Gsr tranny. the car will be most likely daily driven. i was thinking of setting the Psi at about 2-4 Psi for daily driven and then switch it with a touch of a button ( i have a spare Profec B) switch it to 10 or more.


as for the turbo, im thining about a gt28.

engine management will for sure be Hondata s300

i think u have your trannies confused, the b16 is the shorter tranny. imo the gsr is the all round best tranny u can use. its not as short as the b16, and its not as long as the ls. a b16 will work fine though.

as he said dont think about psi level decide how much hp you want to make. stock internals can handle 300whp fairly reliable.

since you're going to have the head off and getting checked out, i would just get a new OEM head gasket, and arp head studs. if u want to make more than 300whp, cp pistons and eagle rods will make the block solid for 500ish whp safely.

heres my suggestions:

less than 300whp, keep it stock with a new oem hg and studs.

300-400whp built block cp pistons, eagle rods, new water pump and oil pump.

400-500whp spring retainers in the head, stock valves, no p&p or valve job needed(assuming head is solid)

proven reliability

what is your ultimate power goal, that will help us help you more.

Oh yeah I meant the b16 tranny and not the GSR. But, balancing the crank isn't neccesary unless you lighten your valve train also to increase RPMs. well,...there's a bit more than that but those are the main components.

ok heres a little update.

tommarow ill be going to a shop... i getting to knoe the guy there(at the shop) because of a friend of mine. hes buys s**t from him all the time. so hes pretty reliable

so as of right now i have a choice of getting 2 things right now... i have $1000 in hand and ready to spend

should i spend the $1000 on a JDM gsr tranny with LSD with only 35,000 miles

-OR-

start buying CP Piston, Eagle rods, OEM headgasket, timing belt, oil pump, water pump etc...

Im kind of leaning towards the tranny because it will be gone pretty quick but who knoes. help me decide guys!

i mean i can get another 1000 by next week so its not so bad. but what should i do first?

as for the turbo, im gonna go with a garret gt28R. its good for about 300HP which is what im aiming for.

I just wanted to say that "YOU GOT A DAMN GOOD DEAL ON YOUR GSR MOTOR!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"

DAMMMNNNNN!!!!

 

[hybrdthry911]

300whp is reliable on a stock engine i wouldnt bother building it unless u want more than 300whp. that said 1000 dollars for a tranny is a little on a high side but it does have the diff so maybe its not all too bad.
