I have two options to go with. in a 93 coupe

a b18b, stock internals, only do injectors and fuel pump etc.
run 8-10PSI looking for 230whp approx

or

a b18c (gsr), stock internals, injectors, fuel pump etc...same thing
run same-ish 7-10PSI

i can get a b18b complete for 1,800
i can get a b18c gsr complete 3,400

i know they are very similar but the gsr puts down more

whats my best bet?
going boost, stock internals on either
looking for 230-260whp on a garrett 50 trim .48ar either way(a peakboost kit)

 

well if you are already going to turbo both and willing to spend 3400 on a gsr swap the difference is 1600 dollars.

you could:

rods and pistons 800
rebuild bottom and top end 400
clutch 300

tune and wope up on a stock gsr.

either way a ls motors make more streetable power on a smaller turbo sooner in the power band and carries way more torque.

 

yea well im on a budget sorta
if the ls will put out 230-250whp daily at 8-10psi without hurting anything its my choice

i would expect a gsr to put out 270whp at 8-10psi stock block but the price is hurtin me a little

 

so your going for the gsr for the extra horses it puts out on lower boost? you should be even safer if you were to buy pistons and rods for the ls. should be reliable

 

well i want the cheapest i can go that will give me almost 250whp on a stock block
b18b should do it?

 

ya just don't rev it like a gsr and you should be fine, if you can try putting some arp rod bolts for some insurance

 

hondas dont like a lotta boost at low rpms. but i would go with gsr, you can get more power outta it if your not pleased, lol. buddy of mine just put down 460whp the other day on completely stock gsr.

but if you only wish 250whp, a 50trim ls will do it stock. if your tuner knows what he/shes doing.

 

either motor in stock form is capable of 300whp...

really doesnt make a difference... id go gsr becuase in the long run, youll want more...

 

agreed, easier to do with a gsr tho.

 

gsr will be stronger stock for stock and you'll have vtec

 

Uhm...care to explain?

 

well a lot of boost at low rpms isnt great for any engine really, thats a ton of load on the guts. if you think about it thats a lot of air and fuel at low rpms where the power isnt at which is just gives it an easier chance for detonation (knock).

 

The reason most people choose the LS over the GSR is the longer stroke (89mm vs 87.2). Longer stroke means more bottom end torque.

If you're really hurting for cash, go with the LS.

It's the power that blows up motors, not the PSI.

 

93 Eg Couper a GSR is obviously the better choice, if you cannot afford it at least get a GSR or B16 transmission, the long gears of the LS and huge gap between gears makes it VERY annoying to drive...

um i see where your going with this but try and tell that to ANY oem turbo car manufacturer, like Mitsu with the Evo X, small turbo that boosts something like 16-18psi STOCK and it starts building boost just about off idle... i'd especially like to see you try and say that to ANY diesle engine manufacturer.

I recall you being an ******* on another thread but i completely agree with you on this one.


Who the eff can rebuild a head and block for $400? 3 Angle Valve job and new guide seals on the head is $300+ alone add a new head gasket and your already at $400 and you have not even touched the block.

yes because a fwd car wants LOTS of torque down low and waaaay more ehhh not so much...

 

yea, but as you said...starts building boost, off course a few psi down low isnt that totally bad, and plus were talking about hondas, not mitsu's or diesels, completely different compression where they can run more boost down low. and that 16-18 psi is up higher prolly around 4k or so, not right off idle.

 

gsr

 

ls and you could get a vtec head for like 4-500 dollars and have the best of both worlds

 

get your feet wet with the LS.

 

LS is 9.6:1 compression one of the eclipse turbo's is about 9.5:1 so the compression is not that far off as you think. none of the b series can build any reasonable amount of boost at low rpm so your i really don't understand your argument at this point... No car can make 16-18psi off idle with a turbo.

 

hmmm i thought 4g63's were 8.5:1, but what do i know?

with a small turbo it can build boost at low rpms, i never said at idle, you did.
