Intake Manifold worth it on sr20det?

[redheadedredtop]

Hey guys, I have been considering the idea of gettting an im. But I wanted your opinions to see if it is worth it, how much it costs versus how much you gained, and where you gained your power. I would guess up top more than down low, but I dont know and that is why I wanted your opinion. Also, there is a link to a no name manifold on ebay.....just wondering if anyone ever tried it.Thanks.Josh

[redheadedredtop]

sry, here is the link.

they could have included some more pics. That looks like an S14 manifold shot from the bottom to me, proceed with caution.

[Onizuka]

If all you care about is top end power (or looking bling), its worth it.

[nismofly]

thats not even like stainless, so it really wouldnt be bling, solely for top end id say

[Juujai]

go individual throttle body damn it

hahaha

that home made looking ebay crap looks ghetto as !@#$ the bores dont even look that big. i'd never put that in my car i'd rather have the oem sr manifold instead. and besides it doesnt even look bling

this one is bling mugen manifold looks like its gonna blow up ahhhhttp://www.todaracing.com/imag...3.jpg

if ur just looking for some extra ponies, try a quality made catback exhaust, stainless downpipe, for a couple hundred bones, if you need more a stainless manifold would be good too. try to do all the mods that won't hurt the cars reliability first. camshafts, cam sprockets would be good too for quite a bit of power for the buck and then you can redo the whole head of the car. valve stems, retainers, springs.

if you have an SR you could just punch up the psi and force more air into the manifold instead of buying a new one lol. if youre driving a n/a honda or 4ag then its more important to build the block and free up all the air you can. n/a cars need to rev high our cars just rely more or less on the slug =)

having itb's on a turbo engine might be a tad difficult

[Onizuka]

The GTiR SR20DET has quad throttle bodies. If you've got to have response, you've got to have response. RB26DETT has six throttle bodies.

i think greddy's intake manifold looks nice...its about $400 though, check one out.

[redheadedredtop]

Well, I plan on running a t3/t4 setup w/ stainless turbo manifold and downpipe w/ 3" stainless exhaust. I was just asking if getting an upgraded im is worth it?

[nismofly]

why t3/t4 on an sr?

eh im just a t25 mani person i guess...gt2871r, drool

[nismofly]

oh please oh please dont say youre getting a t3/t4 because it works good on hondas either

[spanishricer]

I'm going to run a T3/T4 because it'll bolt up to Full Race's top mount exhaust manifold and uses an external wastegate. I found that most T25 manifolds are bottom mount and are meant for turbos with internal wastegates...is this true?

[nismofly]

with one of these

http://www.atpturbo.com/Mercha...e=GRT

thats what my sr setup was looking like, but im not going sr anymore, however i do know several people that run that setup and it sounds amazing

as far as an sr intake mani id say greddy is the only one id really looked into when considering the engine

[redheadedredtop]

I was planning on going with the t3/t4 to achieve my goal of 320+rwhp w/o any internal mods to the engine. Of course that might be a bad reason, but some of the only setups that I have seen making that are using that turbo, or I saw one guy with a t4. I am not totally decided on that, I am still in the idea stage.

[redheadedredtop]

Nismofly, why wouldnt I want to use that turbo???

[nismofly]

that one i posted, the gt2871r, can work with the stock exhaust manifold if you want, and it will get you your power needs there easily with faster spool...and if you ever want more power that one will go to probably 360-370 rwhp

Your just spending extra money for the manifold that you dont need to. There are plenty of turbos that will greatly exceed 310whp out there that bold right on to the stock T25 flange manifold. Plus the stocker is the only cast iron manifold you can use on a SR20, which makes it also the strongest.

Also, if your reason for going T3 is price motivated, concider this: A good T3 flanged turbo will cost just as much as a good T25 flanged turbo. Buy cheap, recieve cheap.

[nismofly]

and as i mentioned those t25 flanged will spool faster, the one i mentioned being not even working hard to reach that power...

[redheadedredtop]

alright, I will have to look into that a bit more. I guess I thought that I would need a turbo that would dispace more air to get that power to the wheels and still maintain reliablity.ThanksJosh

[Juujai]

you dont exactly need to upgrade the turbo if all youre looking for is ~320hp

stocker s15 t28 can push 300no problem with injectors and id suggest a better intercooler of course. with more fine tuning itll push even more. besides the bigger the turbo the more reliabilty you kill. id prefer running 7psi with a t25 or t28 and cranking it up when driving hard to ~300hp when driving hard. besides using stock turbo = save a lot of money haha. the stock turbos spool relatively quickly too.

if i were to upgrade id think about any of the hks gt-rs or gt25 or 28s. theyre costly though

but im not too big a fan of turbos one day i'd want to build a high revving n/a motor into the s13.

oh and most peopel dont really touch the internals of the sr. we just raise the boos tup and if anything breaks we replace it. its cheaper that way.

[nismofly]

but he said he wants reliability, and for that power it would be much better to do a little bigger turbo so you arent putting as much strain on it

also are you saying an N/A sr20de? because the limits of the revving on the KA have been reached already, and it isnt much

[nsrZ32]

on the topic of intake manifolds.....I highly recommend the Greddy one. A couple of my friends run it on their swapped 240's and it provides a pretty decent gain all across the power band.

[nismofly]

id expect that from greddy i guess, then again ive heard bad things about their head gaskets, so i dont know about it from the brand perspective

but i guess that really has nothing to do with this thread anyway

ok back to intake mani's...
