ok heres my motor build
gsr block .020 bored over
type r nipon pistons on gsr rods
arp rod bolts
arp head bolts
gsr head
type r valves
3 angle valve job
resurfaced
supertech valve springs
itr cams.

current intake a exhaust setup
dc 4-2-1 header
stock cat
skunk 2 intake manifold
stock gsr throttle boddy
custom 2.5inch intake
stock injectors

i plan to upgrade to:
edlebrok performer x manifold
65mm throttle boddy
I.M. port matched
aem hybrid 3 inch cold air intake for a type r
hytech header
2.5 cat
rc310cc injectors

would i expect major gains from these upgrades? are they even worth the money spent? after these are installed i plan to get it retuned i do plan to do cams next summer not in the budget rite now but i think these upgrades are pushing me into the right direction.

 

This is my opinion...

Hytech header is good. Although, I am assuming that you are getting a replica header unless you have deep pockets.
High flow cat is good.
Intake is okay, but I always recommend the comptech icebox. I have seen the highest gains with this intake.
I would say hold off on the intake manifold and the throttle body for now or at least until you get cams. I would imagine that an Edelbrock manifold wouldn't give you the gains that you expect. Stick with the Skunk2 and stock gsr throttle body.
The injectors are always a good idea. You may need them later when you buy cams and re-tune your motor.

You could expect gains from the header, intake, good exhaust (that stock cat is robbing you of power), and it will make tuning more efficient with those injectors.

 

Purpose of the car? Roadrace, drag, daily driver?

Suggest you wait and do cams and porting at the same time. The performer might not be the best choice due to the size, it fits vey close to the firewall and a fuel filter relocation will probably be needed. Plus you'll need to hack up you arm cai. Rc310 are old tech, run some rdx's for better spray pattern.

 

It's my daily driver the hytech is real I'm buying off my buddy used and it's not that I expect these to bump me up in hp a lot it's kinda just in preparation for cams and the performer x will be close in a dc chassis? Also I looked into the rdxs seems like to much work to even be worth it.

 

Too much work?

 

From what I saw u need to buy a custom fuel rail to run em

 

Please take a look at the links below. I have a very similar set-up to yours, nearly the same. You should find some answers in these posts.

Picked up my SMSP header, more power soon

Disappointing Results with a Performer X, huge torque loss and minimal hp gain
https://honda-tech.com/forums/all-motor-naturally-aspirated-44/disappointing-results-performer-x-huge-torque-loss-minimal-hp-gain-2776313/

 

Thers a lot of other info backing the performer x, i think your the guy who modded the hell out of the stock manifold which really seems to help that midrange, and hytech real is a good choice man

 

after looking thru his threads ^ i think im just gunna stick with my skunk 2 manifold and pickup the comptech ice box a 65mm tb and a 2.5 cat with hytech header those seem like i will get the most benifit out of them and im still getting the injectors i mite just pickup some prelude injectors for now if the rdx's fit with a stock rail id run em but it doesnt seem worth all the work just for a better spray pattern ex: new rail, cuttin wires when i can get a obd2-1 jumper for my harness and run sum rc's or prelude injectors

 

AFAIK the RDX injectors just need adapters to go into your rail. You don't need a new rail. RDX + adapters is still cheaper than RC and not really any more work.

 

Sounds like a good plan. I actually had my stock GSR TB bore out to 64mm.
Get the RDX injectors. The improved spary will net you more power. Just get the the jumpers for them, no wire cutting.
You should also look into Deatschworks, FIC and ID injectors. All of these have a better spray pattern than the RC's and the Prelude injectors.
I have a set of ID725's that will be going in with my modified GSR manfold next month.

 

i went thru the whole thread and ppl said they saw no power improvments with them? and didnt see anything about a jumper harness being made for them i guess ill have to look more into it

 

There's a bunch of ways you can go, depending on how much DIY you want to do. The main problems are that the injectors seat differently and that they have a different electrical connector.

The advantages are a superior spray pattern that some people claim is worth a few ponies and that you'll be farther from saturation (because they're 410 cc).

To get around the seating problem:

1) get a custom fuel rail (from Rosko)
2) get adapters (Xenocron sells these -- not too expensive)

The adapters just let the injectors fit into the stock fuel rail.

To get around the wiring problem:

1) get premade adapter harnesses (I think there are ones that connect to your current harnesses, as well as ones that replace your harnesses -- also on Xenocron)
2) get adapters with pigtails (plug the adapter into the injector, then splice it into your current harness)

Obviously, the more work you do, the cheaper, but it's easy and not too expensive to just get replacement harnesses. All the stuff is available from Xenocron, who also sells the injectors, or you can probably get it from some of the other H-T sponsors. You can also find cheap pigtails on the Marketplace.

 

As far as RDX injectors...here you go http://www.xenocron.com/injectors-rd...s-c-30_98.html everything you need.

 

oh sweet ill run those then, what do u guys think ill be looking at for power with this setup? i was thinking 170-180ish?

 

lol not a popular question around here. You'll make about as much power as an ITR with I/H/E. Dynos vary so power is more subjective than it seems like it should be.

 

alrite thanks im not big into worrying about numbers im more of butt dyno guy if im happy with how she pulls thats all that matters numbers on paper mean nothing to me lol

 

Thats my preferred way of looking at it. Numbers on paper are all well and good, but how it performs when your actually driving it is what counts in my opinion.

 

Here is an ITR that was justed tuned. You should be near this power level.

so i just picked up a 65mm throttle boddy and a 3 inch intake and some 310cc rc injectors for a steal of a price tb is a perfect match to my skunk 2 manifold so no portmatching needed i should be pickin up a 4-1 header this week with a 2.5inch collector and im looking into 2.5 in high flow cats, cars not gunna be dynod till the spring probably but ill let you guys know how the butt dyno feels with these upgrades

but on a side not im deciding should i run oem honda intake manifold gasket and headgasket or go with a hondata im gasket and looking into a golden eagle head gasket ( head isnt on block yet just got redone)

 

so i found out my 65mm tb is a stock itr thats ported out
i ended up getting flat face valves instead of itr's
motors in car running great doing a tune on tuesday and then hopfully a dyno run in the next couple weeks heres my final setup until i upgrade

gsr block milled .020
gsr head milled .020
itr pistons
gsr rods
gsr crank
arp headstuds
sk2 manifold
ported out itr tb
310cc injectors
hondata im gasket
supertech flat face valves
supertech dual valve springs and titanium retainers
itr cams
dc 4-2-1 header
stock cat
ws2 cat back
3 inch long arm intake
plans for the future:
gunna work on a cold air setup
a better header
a true 2.5in exhaust
test pipe
in a year or two prob upgrade to a set of ddtech cams or skunk 2 pro 1's
