what compression is the block now?

Port the head would be my advice

 

details on the motor would help....

what does "gsr motor punched out to a b20 ported head" mean?

 

Let us know a little more about the setup...comp ratio? Ported head as in??who did it what's done....and we will gladly try and help you with your goal

Ah, the elusive comma. Where exactly do you go?

Anyway, just because the head has been ported, doesnt mean its been ported well, or to its full potential. For a good example of what im talking about, search for archived posts by member TBone. There is a thread titled something like "the destruction and reincarnation of tbones cylinder head". If you dont know how to search, this will be good exercise.

 

well its punched out to a b20 as in a different crank and bigger pistons..
comp is 12.5.1
ITR intake ported
255walbro fuel pump
370 rc injectors
3.5''intake thru the head light
B16 head that has been ported as in specs im not sure.
toda spec c cams
this motor was one of my buddys and he sold it to me im not that much of a honda guy as u can telll my my SN..lol..
i wanted to go more compression but im not sure what size the pistons are cause i didnt bild the motor..
sorry i couldnt give u alll the info u guys need to help me out but thats all i know about the motor..

i also wanted to switch to a edelbrock performer x intake and port that..

dump the exhaust do u have a v stack?
how good is the port work
cut open the mani f u think ur motor is being coked

 

no v stack and for the port work its just a mild port work as in cfm numbers im not sure..sorry i cant give good head work info..

 

get a blox v stack 4show power u may not feal a differance but it'll help
port the head better
do u drive it on the streets?
and wut do u mean cant give good head work info? u dont want 2 or ur not sure about it?
**** i dont care about cfms its about how that [freak]er rips at the track!!!! look at ur runs and ur power band and u'll know f that ***** flown!

 

not to sound like a jerk but how do people buy cars with buily moors/swapped motors and not know all the details of what they are buying?

 

i cant give head info because i dont know what all was done to the head..yes i drive the car some times on the street to(to the track and back home)..

and for mike_s i got the car stock and if u read the post u can see i said i got the motor from a friend..

i dynoed the motor it dynoed 224hp and 150trq and my track times were 12.6 at 108..

 

if i go with a blox manifold and port that to my head and throttle body would i see power gains..my itr is ported and port matched to the throttle body also..

...god what happened to the English language....


Allmotor65stang....I understand that you're not that sure about Honda engines and that's fine but why do you want to raise your compression over the 12.5:1 that it is now and why do you want to change your intake manifold to a Performer X?

The best thing for any person to do, who is into cars etc is to understand them before trying to modify them. Imports and domestics do not respond the same to the same modifications. Various import motors do not react the same to similar mods. It's important to understand what you're doing before you do it don't you think?

That sounds like a very healthy motor. At 12.5:1 how much higher in compression can you go (rhetorical question), lol. Think flow not compression. compression is only a second order effect.

You mentioned a hytec header. What sort of header are you running now? maybe SMS or DTR is what you are looking for for those last 6 to 8 whp. Also you mentioned 3" exhaust, that definitely helps.

Getting to those last 6 to 10 whp is going to expensive.

 

if i go with the edelbrock performer would that be better on my setup or the victor x..the only down side is im not reving the motor to 10k only 9250k..

Also the head i did find out is race ported..

some 1 correct me if im right on the cam specs..

toda SPEC C..IN250/11.0mm EX250/11.0mm
vtec 300/12.5mm

skunk 2 PRO 2..IN270/12.8mm EX276/12.0mm
whats vtec pn skunk2 cams??

 

Any body

 

Those numbers for the Skunk pro 2's are the VTEC lobe. I'm not sure if they list the lobe specs for the Primary/secondary lobes so you may have to call them to get those. I'm assuming that you're trying to determine which cams are "bigger" as you are wanting to run the largest cams between the two?

If that's the case and you are serious about racing, I would suggest that you buy both sets of cams, test them out on your motor and keep the ones that work best, sell the other ones. Both of those cams are excellent so you can't really go wrong by using either of them.

 

thanks that helped me out..ill have to call skunk on monday then..

well i have toda c allreday and i made 224-150
i may buy the pro 2s and see if i get a power gain..

 

You can usually find some used pro 2's on here for fairly cheap prices. try searching pro 2 and you should get lots of FS threads.

 

forget cams for the moment, buy 3" exhaust.

 

i would think a 3' exhaust and a victor x manifold,they seem to do well with 2.0's. also you may want to consider sending the head to a expert,not all p&p's are the same quality. you may be suprised what you can pick up on just a good 3 angle valve job if the one you have is subpar

 

i do have 3'' exhaust from the header back to the middle of the car.maybe i didnt explane myself right in the first post..

im gonna try the skunk2 pro intake and port that.

also any other info u guys have fell free..
