I was thinking about going with the following setup here for my future plans just for ***** and giggles until my boost project is complete, because I want something fun already.

b18c1 or b18c block
Gsr crank balanced
Honed with CTR or ITR pistons
arp rod bolts
Arp headstuds
Type R cams and type R valvetrain
b16 head with b16 transmission.
stock p30 ecu or tuned and chipped p28.

I just wanted to figure if I should go with jdm p30 pistons or itr pistons ?

Will there be any dangers with p30's in a GSR bottom ?

I've done research and I hear p30 pistons have the highest compression.

Plus is there anything special to this swap, like can you use the gsr oil pump, water pump, timing belt, etc ? and like a regular b16 or b18c1 headgasket ?

 

bump.

 

What makes it a poor mans typr R is using a GSR block and ITR internals. Since the GSR crank is the same stroke as the type R and so are the rods, the easiest thing to do is install type R pistons and now you essentially have a type R block for less than a type R block. IF you truly want a poor mans R then that's what you do, if you want a specific compression ratio to go with the rest of your build plan, then you use the appropriate piston to accomplish that, whatever that ends up being. If you do that, it's no longer called a poor mans R, but who cares.

 

I say p30's or ITR's will be nice. Just go with the one you like more, but since you're just using ITR cams I'll just stick with ITR pistons. Oh and first thing tune the car when its done.

 

so go with ITR pistons and rods ? Question .. is the rod length the same on the ITR as it is on the B16 rods ?

 

nop no way are those rods the same

 

Okay. The b16's are shorter right ?

 

yes. why? You're building a poor mans R right? that would mean that you're using a GSR which has the same rods as the type R.

 

okay, just checking. yeah. ima use gsr's. i can use the gsr rods with itr or p30 pistons right ?

 

Random question on my built of how much whp you think I can make. Sorry for asking here ht wont let me start a thread.

Type r head
super tech flat faced valves
rocket motorsports m24x camshafts
rocket motorsports spings and retainers
race port and polish
Skunk2 1st gen IM with skunk2 68mm tb ported to match manifold
oem honda headgasket
try y headers with exhaust cut out

Gsr block
gsr micro polished crank and balanced
arp rod bolts
arp head studs
type r pistons and rods
b16 tranny
honed hot tanked etc

So again just wondering how much whp you think this setup would make on the dyno?

 

Gotta dyno to find out. Its against the rules to give guesstimates on HP numbers on setups. Good luck

 

Thanks. You think that this set up is a good one for what it is?

 

My main concern is if this set up will be reliable and fast enough for having a stock bore.

 

You really should be starting your own thread instead of hijacking someone else's. What makes an engine reliable are 3 main things:

1- Quality of parts used.
2- Quality of machine work and engine assembly.
3- Quality of the tuning system and the tune running on it.

What makes an engine fast are 4 things that are the same or very similar:

1-Quality of parts used.
2-Quality of the part combinations being used on the motor. (how well does each component compliment the rest of the build)
3-Quality of the tune that your engine is running on.
4-Quality of the driver/driving ability.

Those are really big cams you're running on that motor, are you sure they're a good match for your build as it sits?

 

I've tried but HT keeps saying I'm a trial user for months now.

Those are big cams and I'm worried because of the stock bore mainly the head I'm fine with but not knowing my exact compression ratio is hard for me to determine if those cams can even be used to full potential.

 

It keeps telling you that because you would have had less than 5 posts. You need more posts.

Who put the motor together for you?
