okay i have a b18c1 and i want to do a poor man itr how would i go about doin this and what would i need ? * new* here also i searched around and all i get is ls/vtec stuff and b20/vtec i would appreciate it if you guys can help me out or link me somewher that tells me how to do it the *right * way.thanks

 

ls vtec is only if you dont have a vtec motor, well you have a vtec motor.

So lets see here, how to turn your GSR motor into a type r....that is easy, but a type r motor. It can be done but by the time you are done you will have more money invested in your motor than you will in just buying a type r

 

Just turbo that bitch and smoke type r's all day

 

put an itr head on it...

 

upgrade your valvetrain, new cams springs retainers, intake manifold, throw the red valve cover on it and call it a day

 

hahahha wow so thats all i need is itr head then im ccomplete?

 

might be the stupidest thing i have ever heard? be happy with your motor

 

technically..but you wont have the same gearing

 

yeah i'm pretty sure the only thing a R wil have on u is higher compression... and a better tranny. but u don't want high compression anyways, so u can boost that bitch

 

man so now i dont need an itr head somebody posted it in here so i jus went with it but any other suggestions and all im hearing is boost it boost it! so i guess turbo must be everybodys favor.

 

itll give u wa more power than spending money on a "poor man's type R" just make sure u research turbo b4 u get it.... cuz if not ran right turbo will b the death or ur motor.

 

there are a few differences. cams, springs, intake manifold, pistons are the main differences, and tranny obviously.. but if you were to just get an itr head you would want to use the itr ecu also....


but boost will definately give you some power if thats what your looking for... just remember.. if you boost it and dont tune it properly or boost too much without upgrading your internals to handle the pressure, your gunna run into some problems.. if this car is your daily driver.. you might take this into some serious consideration..

aaaaaaaaaaand im done.

 

A "Poor Man's Type R" is by definition not an ITR motor, or even an attempt at recreating it in exacting detail. A "Poor Man's Type R" is simply putting a PR3 head on a P72 block.

 

thanks for all da feedback .

 

I thought the b18c1 was the poor mans ITR

I've read a few threads where people referred to the poor man's ITR as being a b18c1 short block with a b16 head, but as far as converting the b18c1 into a poorman's ITR motor.....
it's the wrong goal, rather see how you can improve the b18c1 for NA if that's the way you want to go (lots of threads on that).

edit:
haha, kendall beat me to it....that's what happens when you open several pages at once to read.....and then make a reply on one of them

 

Just get a b16 head, and put type-r cams in it.. throw that onto the b18c1 block

Then get some itr pistons and throw those into the b18c1 block

Match that up with an itr tranny... and bam! ITR spec... lol ..

Just save your money and get some good cams and valvetrain.. raise the compression somehow (p30 pistons, ctr pistons, itr pistons, jdm gsr pistons, aftermarket pistons, milled head, thinner head gasket, etc etc..) and a good ecu, like hondata.. take the butterfly plate out of your gsr manifold.. get a good header, dyno tune it, and bam! Your makin high 100's to low 200's at the wheels.

I wouldn't go that far, but a lot is definately possible.

 

i dont think there is such a thing as poorman type-r, no matter whether switching heads, pistons, cams, etc, its gonna cost you some $jack$
goodluck

can always depend on kendall with the right info

 

What's this about removing butterflys?

Pardon my ignorance

 

With my gsr, as well as my friend's turbo gsr, we removed the butterfly plate, got a new plenum gasket, and went to the local hardware store and got some shorter bolts.. we then removed the studs that are there, and used some shorter bolts in their place... and there ya go.. shoerter runners, and no butterflies there to disrupt airflow. It made a difference on my na car, and an even bigger difference on my friend's turbo car.. Im going to try and get dyno proven results, so that I can prove that it is actual hp/tq and not just in my mind..lol..

BTW: We also gasket matched the runners on my friend's manifold..

 

weird, ive been in this whole honda scene for a while i think... and id never heard that. i thought the butterfly valve was praised... anyway... when is it "necessary" to remove it? i mean, are you gonna see gains with basic bolt ons? or is it a once you have new cams type of thing.

 

BTW...if you're going to put an ITR head on it you'll lose about .1 or .2 on your compression ratio (so you'll be running about 9.8:1 or so). The combustion chamber on the ITR heads are just a little bigger b/c of the porting done at the factory. If you want to raise your compression ratio wou'd have to mill the ITR head or change your pistons (which would be the right way to do it).

Also bear in mind that the intake manifold for the B18C1 will NOT bolt up to an ITR head (the runners/ports are different) so you'll have to change that as well. Then, you'll need to change your ecu since you'll be losing the secondary runner operation from the B18C1 manifold.

So the short of it is, you'd be better off ($-wise) sending out your GSR head (or finding a good core) for a good port/polish/valvetrain uprgrade if you want ot go that route. If you're absolutely set on OEM ITR stuff, it'll still all fit onto a GSR head anyway, but there is aftermarket stuff galore if you want to go that route as well.

Either way...you're looking at well over $1000 all said and done. In my experience with cars, determine how much it'll cost you on paper, then double it!

Actually, the combustion chambers aren't even touched from the factory. The bowls (areas between the valve guides and the valve seats) are the only things that are ported. A PR3 head is cast with a larger combustion chamber.

Or use a thin headgasket.

 

Ahh...I thought they did hit the chamber. Good to know! Either way, if you polish your GSR chambers, you certainly will lose a little compression (and yes...you could use a thinner head gasket to offset the losses).
