ok, sorry if you have heard these questions before, I want to get a motor built, I have a ls with 150,000, that will be coming out.

I don't know what a built motor really is? are all parts new, except block?
what is the process from block, pistons, rods, head, cams, valve springs, intake manifold etc.

also i am looking for a 210whp give or take all motor, for everyday to work, reliable fun driving.

I am confused on compression, and don't know much about motors. should i use aftermarket pistons? manifold? cams? are they more durable and relieable?

should i go,

1. gsr-ctr pistons?
2. gsr-typr r pistons?
3. gsr-stock pistons?


should i go,

1. stock gsr head?
2. gsr head typr r internals?
3. gsr head with aftermarket valve springs cams?

I want relieable fun.


thanks in advance for your help

 

Do some researchin on here for other peoples setups that have your goal in mind that will be a bunch of help for you. If you dont really know your way around a motor you should really think about having an experianced builder put it together for you. Plus he can help you achieve your goals and help you decide on parts.

 

i have tried searching for compression and piston topics and found nothing.

 

you can go on http://www.zealautowerks.com/bseries.html to look at the variables?

I would go with usdm itr pistons,rods and the gsr head with itr valvetrain! just my opinion!

 

just go with a type r motor if you aren't sure. and then you can add aftermarket IM, Headers, TB, injectors, fuel pump, and a quick tune with hondata.

 

You may want to pick up a basic automotive technology book and learn how an engine works before you start anything. If you don't have a working knowledge of how the various parts work together you can never know what parts to pick. If you are unsure have a professional build the engine from start to finish. If you pick parts based on what other people on the internet say worked on their cars you are more than likely going to waste a lot of money.

 

v8 eater, thanks for the link.


I am leaning toward CTR pistons gsr block, with stock gsr head. I may want some type r internals. and poss a after market manifold, intake, etc.

what compression will this give me? and what would be the average whp?


I know the compression will be high, and i will need to use premium fuel.

if anyone is running ctr pistons in a gsr block please chime in. i would really like to know how they run.

thanks

 

Your compression with that setup is going to be high. ~13.1:1 -13.3:1. Your tuner is going to have to pull a bunch of timing to get that setup to work on pump gas. If your going to be daily driving the car i would not go over 12.5:1 that is pushing premium.

You need to do research. There is a bunch of good info on here.

 

Cheapshot- if you really don't know what you're doing, or have a good understanding of what an all motor build is, how will you know which advice you get is good and which is bad from people on this board?

 

see this is the worst way to send a person if they arent sure a type r motor is simply a bad desision to (build up) on a budget. id say go gsr and then bolt on intake manifold and exhaust ect. and get roughly the same hp give or take 10 hp. but for the extra 2000 hed spend on a type r motor it think id rather save teh cash. and a type r motor simply isnt for a a person uneducated on the topic. its sorta like the old ladys driving 911 carreras and z06 vettes around central pa. it just isnt the right car for the owner ( that happens alot aroudn here for some reason

 

I see what you guys mean, I am looking into some stuff and learning slowly. I know it makes sense to use a gsr over the typr r for price and power.

I would just like to hear what people recommend, and why they recommend it, over another setup etc.

after I could always look up what setup they perfer and go from there, to see if I may want that.

 

best way to do it

 

like scott tucker said pick up a basic automotive technology book. How to Rebuild Honda B-Series Engines is a good book.

 

i know the book will give me a better understanding of the b series engine.
but i am not building the motor, the guy building it has lots of experience, I believe he know or works with people at endyne. he has built many super modified motors that have run great times, as well as everyday drivers.

say i go with gsr block ctr pistons, gsr head and manifold. I put a intake and high performance headers on. what would i be looking at in terms of power?

would mods to the head be necassary ? or ok for everyday driving?

 

Man try to avoid the ctrs imo. Like I said before the really put the compression up there and if your going to be dd the car they are going to have to pull a bunch of timing. You could have a 11.5 motor be faster.

 

a type r engine is $1000 more than a GSR and also worth it since the mods so many GSRs get are already done. consider that the type r has

1. basically a stage 1 cam
2. a single runner manifold
3. a good factory header
4. more compression
5 slightly better VT
6 drastically reduced tuning costs since a p73 is close to perfect.
7. 27-32mpg

if you're going after 180whp the jdm itr will almost do it stock. a high end header and possibly a little more timing in the tune can get it there. JDM importers are unloading these things if you haggle with them. long blocks will get shipped to your door for under $2800 total

if your goal is more than this, by all means a scratch build may be a better idea. then again i would probably look at a k20 type r engine. still spendy but it's not really more than a totally built and tuned b series could cost when murphy's law is taken into consideration. also factor in the countless hours of getting parts, being on the phone and talking to the machine shop. cost vs cost i'm a big fan of OE honda engine swaps. simple, easy and reliable.

 

H2B haha

Gsr block, gsr rods, P30 pistons (jdm b16 pistons), B16 (pr3 head) don't deck or mill unless neccessary. Supertech valvetrain (valves, springs, retainers) send head to combustion contraption for street port and all things installed, and some skunk2 st2 or pro1 cams topped off with a B16 tranny with 4.78 final drive.

Man that would be fun again if I wanted to rev to the moon.

I will keep a stroked and poked H22 though.

Good luck on your journey OP and do lots and lots of reading before you jump off the high board. If you don't do as much as possible yourself it gets expensive fast.

 

drivesideways, your saying that you would buy a itr for 4500, over getting a completly built motor droped in and tuned for 4000?

sauceja i want to rev to the moon, lol

I am sure people here have run gsr block, with ctr pistons, with no problems.
If you are one of them or know someone who is please chime in.

thanks

 

Cheapshot- if you have a really experienced engine builder building your block for you, he's the guy you need to be talking to and asking questions. Don't you think that it's better to ask a guy that you trust, with proven experience behind him, than people you don't know on the internet?

 

Exactly. Talk with him about your goals and what you would like out of it, and he can give you options on power vs. costs and brands ect.
Obviously the one putting together the motor should have all the insight you need and know just what to use.

 

I love people who are living in reality.

 

what exactly are you wanting from a motor?? let's ask the obvious question first...

if it's a daily driver, the recommendation may be different than something in auto cross... Do you want something that is high reving, something with lots of torque?? the answers to those questions will help recommendations too... and go through the dyno thread... you can learn a lot from that, and then read comparison threads of product xx vs product xx.. why it works and why for different setups and situations... combine that with the suggested engine basics book, and you'll pick up a lot and be able to make an intelligent decision when it comes to selecting parts..

 

that answers the question. type r trannys gor for about $1k these days anyways. it is worth it to buy the type r motor over the gsr motor if you have the cash.
