Hey there, I recently had problems with my valves on my 98 GSR and Im kinda glad as I was about to start upgrading my stock car anyways.

Either I switch the head, or either I fix it and put performance valves and cams etc - either I change the head completely, for and B16A or a B18C5 one and change the pistons in my block accordingly, then change the ECU (HONDATA) if needed.

Question is, wich setup is better? keeping my current stock GSR head with improved parts or changing the head + pistons (and maybe crank).

I am not looking for the cheapest solution here, I know the first one is much cheaper, but Im looking to find out if the 2nd choice is worth it for a price <--> performance ratio.

What would I get with a B16A head of my baby? or a B16C5? any other relevant parts need to be heavy-dutied if I do so? I there a better ehad than the 2 I stated that would make a better job on my block?

Either scenario I pick, Im also upgrading Exhaust Headers and Intake.
Another thing I should specify is that my goal is to get the best performance I can get without a turbo.

Thanks for any advice and for your time all.

 

Actually the first scenario is the best imo. But you are very wrong about it being the cheapest. Look up the price on cams and upgraded valves and springs. That and the cost of either a 3 or 5 angle valve job(which I recommend).

 

No No because if I go with the second setup, I still buy new cams and valves for that new head. Sorry for not specifying.

 

oh, i understand. I would still use the gsr head though. Especially since you already have it.

 

Any pointers on mods I should do to get about 200-210 HP ? Without a turbo... i

 

Bump Bump Bump

 

id say keep the gsr head but get a single stage intake manafold tho
rebuild the gsr head and have it ported and polished, unless u just wanna buy a c5 head

y do u need to rebuild the head if u replace it with a c5 or something?

 

I want to figure out what would be the ebst between rebuilding my GSR head, or getting a new ITR head.... and the diffrrence in the performance it would give...

Im trying to reach 200-210hp

 

well, the way i was thinking, y build up to a ITR head, just buy one, u have a good base already, build up from there

 

If I put an ITR head, are the stock valves heavy duty or should I replace em for titanium ones or something? Same question for cams.

 

I say just keep the gsr head and have it built since your already have a gsr and put some high compression pistons.

 

i have heard that titanium valve springs are good for race only- like they dont last long for a DD car.

i still recommend the itr head and then sell ur gsr head

I agree. Build the gsr head. Why it is off, rebuild your block. Maybe overbore? Up your compression(different pistons,deck the head/block, thinner head gasket). Definately port and polish, 3 or 5 angle valve job, up grade valves, valvesprings, cams, etc. And last but not least, my favorite, ITB'S. I LOVE ITB'S. With the right combo, you can easily yeild 200+ to the wheels. Dont forget you will still need engine management. I highly recommend uberdata as far as functionality to cost is concerned.

 

ITB's? Sorry for my ignorance

ITB's = Individual Throttle Bodies

Not for the inexperienced or the light of wallets.

As for head choices, the B16A head is probably the best flowing when it comes to stock B series. If you take one of these, mildly port it, polish it, select a good cam shaft, that'll help you be on your way to your HP goals.

 

You can do custom itb's pretty cheaply.

 

on a stock motor, how many more horses are gained from ITB's compared to stock, or a bigger throttle body?

is it really worth that much money?

I'd say FI instead, but thats just me

 

On a stock motor, not much would happen but throttle response would get better. To really make use of itb's, you need higher profile cams. I like itb's because that just me I guess. I respect turbo people but I don't want one on my car. I would rather build a motor that can handle a good shot of nitrous but still be quick without it. My reasoning for this is so I can easily drive it everyday reliably but when I spray, all hell can break loose. I like the idea of this, some don't but to each their own. Hence the reason for separate forum sections(integra, civic, all motor, fi, etc). If we all like the same thing then the home page of honda-tech would just open up to all the posts in one area. What a mess that would be. LOL.

 

BTW- Yes I realize nitrous is technically classified as forced induction so my wording may seem somewhat redundant because he used the actual term 'fi'. The thing is, I dont like nitrous being classified in FI with turbos and superchargers as we all know that it is really a whole different world, but technically still 'forced' into the motor.

 

i would rebuild the GSR head.... i swapped out my bottom end in favor of a ITR bottom end but i opted to keep the GSR gead... althought with 133k miles i went ahead and purchased CTR cams with rocket motorsport titanium retainers and dual valve springs along with new valve stem seals and cleaned up the gsr valved which were still in great condition oh yea new valve keepers too...

i kept the gsr head because it yields higher compression on a itr bottom end then a b16 or ITR head will and along with a single stage intake mani should yield simlar results beside the slight port and polish the ITR head comes with....

if you slap on a ITR or B16 head onto your gsr b18c1 block you will lose a little compression just a heads up
