View Full Version : so Im going SR...

so iv decided to go SR on my POS...due to the fact that my S14 KA swap went to shit...


im not askin the obvious ''how hard is this'', my question deals with exhaust situation

my chassis is a base model 90 pignose...exhaust is still stock...

may question is... will the SR header connect to the stock SOHC downpipe...? ,....seemingly stupid question...but one i need to ask...

i ask this because when i did my s14 KA swap into the chassis i ran into the problem that the stock sohc downpipe flange and the s14 header flange were way different...

lucky me i figured out just use s13 DOHC header and im ok...

im considering going redtop...since obvioulsy cheapest of all sr's...sayin i go red top, will the flanges meet up... or whats a solution i guys can give me...and what if i go 1st gen black top?

when i looked at my exhaust the first time i was shocked to see welds not flanges...which is suffice to say not pleasing...

as far as the swap...i know the basics of...engine, tranny, ecu, harnes, ign ship,MAF, are the commen known parts needed to swap an SR in...

but is there any specifics people leave out of the big picture...


for example again...wheni did the KA swapped no one told me about the headers situation...and the EGR pipping having different bends...or that the temp gauge wont read properly if u dont change out all the sensor to OBI

please dont kill me for this one...i did search but i couldnt find diddly...though i did learn some good pointers in the Fact thread for this motor

you'll have to re-rout your power steering lines or move the resevoir to the opposite side of the car, because the power steering pump on the SR is on the opposite side, other than that everything bolts up, im not sure about the exhaust though. but thats one thing you need to upgrade when you do the swap, not just for power reasons but you need to get rid of the back pressure that the stock exh. will put on the turbo. i bought my engine from engineland.inc.com, it included the engine,tranny,ecu,wiring harness,MAF,and all the goodies like the alt., starter, turbo,p.s. pump,a.c. pump. i paid $2500 shipped for my S14 SR. its the third engine we've ordered from them, and no real problems.

You really need to search harder, first of all turbocharged SR's don't have headers, they have manifolds. All you need to bolt a SR to the stock exhaust is a SR downpipe. You can use either an aftermarket one or the stock one (stock as in off the SR). It's really simple, it goes head - manifold - turbo - turbo elbow - downpipe - catalytic converter - rest of the exhaust. It's the same for turbocharged redtop's and blacktops, all the same shit.

so i have the lines and everythign for that scenario

SHIFT_Slide: sorry for being the dip shit here :wtc:...im totally new to turbo...ive worked on a few ITB'ed KA and N/A set ups only...

Sr's are just a new ball game

It's all good. One thing that bothers me is when someone says you NEED an aftermarket exhaust, like the stock one will kill the SR or something. What do you think the engine was mated to BEFORE it got shipped over? It's like people assume that 180's and Silvias rolled out of the factory with 3" exhausts stock.

my thoughts exactly...all i hear is people with 240's in my area is 2.5 to 3'' piping ''is a must to run sr's'' and i just give them the ''ur an idiot look''an walk away...

cuz u know... every 180sx is nismo tuned to the max :jerkit: ...

thanks for the help +1 rep for u good sir and ur curteous attitude...highly refreshing around these parks

the only real reason why you would want a bigger exhaust is that it helps the turbo pull more air in = more power. turbo's love big/open exhaust. :)
but ya nothing is wrong with stock if you want to drive like that for a while

nah yeah that i can understand...but the way the put it is like without it...ur car is rendered useless ur f*cked in the a** till u get a straight pipped set up...

i just laugh everytime i see a useless straight pipped car get pulled over for noise pollution lol...

plus once i do decide to upgrade my exaust...biggest ill go is 2.5 with a selinoid (sp) or 2

im keeping it semi stock...

talk about a shot out of left field with no warning bro...jeez

Honestly, you don't need a massive turbo to take advantage of a 3" exhaust. You'll be fine rolling around with a stock exhaust, but you will see more performance out of a 3" exhaust than you will out of a 2.5" or 2"*, even without some huge turbo. There are plenty of 3" systems that will be pretty quiet on an SR.





*(for the love of God, don't put on a 2" exhaust, you might as well leave it stock. That might even be the stock size, I can't remember)

im still researching what i wanna do for exhaust...i dont know much on it so i wanna figure things out...ask minimal questions on it...

um 'insanely large turbo and crazy set up' [i.e. drag only car's] would usually have bigger than 3 inch exhaust. will it mate up.. i have no idea... will it hurt it no... does it make sense not imo but its your car

Then why are you gonna get an SR?

You'll end with more of a head ache If your gonna install an SR with no idea about it.

Your better off sticking with a KA if its for DD.

ive learned a few things here and there about the SR

not just that...everyone i know with either S13 or s14 owns an sr in there car...so parts are easier to come by then KA's lol

ive given the KA sohc and DOHC a good run...so i wanna move up to SR...itll give me a good oppurtunity to drive a boosted car...will this be my first boosted car ...yes...i gotta learn somewhere

Last time I went to the JY there were plenty of KA parts, didn't see any SRs though. Stick with the KA if is just for DD duty but it took me 3 SRs to heed my own advice.

whats JY?!!?

its not just gonna be a DD its going to be also for drift events...and some autoX

trust me ive read everything i could on KA's and what they can do...its just for the same price as a properly done KAT setup...or even a well built KA N/A, its around the same ball park as Sr or CA...so why not go with something a bit newer, with less miles, with more HP stock...

though ill def will miss the torquy KA lol

I have a tanabe concept g and with a cat the car was very quiet and its 3in. once I put a test pipe on it the 93db went out the window but still less noise then nur spec I had. I have the tanabe for sale pm me

ill look into it...but like i said i just needed some clarificationson exaust matters...shit so this means i need to get a whole new exaust...
like i mentioned earlier my shit is all welded together...and the nearest shop is about a mile away...

Fair enough. I thought you said it was only for daily duity.

I personally have the 'been there done that' lethargy with SRs and have mellowed out over the years. :2f2f:well from all the topics iv read u know ive come to my own conclusion about it...especially if u wanna do things right and not take shortcuts...which for somehting that in a sense im trusting my life in... i dont wanna do u know... and i dont wanna buy someone's used set up or zip tied contraption...if im the one zip tieing im the one who will deal with it....but i rather just not sheap out on it...:bigok:

wtf is your question. the thread ended after koukimonster's comment.

exhaust is usually the first mod. it has one of the best horsepower/price ratio evar. people were bolting bigger exhausts to their model T fords back in the day for more power.

bigger exhaut will help the turbo spool up faster and the engine will breathe better.

and depending on your choice of exhaust resonation and/or cat/test pipe configuraiton, your exhaust will sound tits.

stock exhaust = gay.

oh yeah, and if you plan on going SR, kiss your EGR goodbye.

in fact, kiss all emissions devices goodbye:naughty:

i wasnt at all saying that he had to have one. i was simply stating that it would help him in the long run. assuming the turbo he ends up with is in good shape, the reduced back pressure will prolong the life of it. not to mention keep his options open for more power. i know the stock SR vehicles werent equipped with a 3" exhaust from the factory, i was only saying it helps.

bro man...relax

my answer has been found were just goin on other questiong i had aswell

and the whole Emissions....i kinda figured that out seeing as...welll yeah its a commong knowledge thing...

but i have my ways so its now an issue...plus the car was just smog recently (bout 5 months ago) when i bought it and it had the single cam still in it...so i dont have an issue about if for another year and some change :bigok:

no biggie u helped me figure out that in the end i will need that downpipe sins its totally different from what i currently have on it

i like this guys point of view. just in a more subtle way....lol. im glad i could help you out. i drove mine with stock exhaust before i got my aftermarket in. and its daylight and dark. and +1 respect for not being afraid to ask questions.

if you want to change your turbo to manifold gasket once a month, then by all means use an exhaust that is less than 3" but if you want faster spool, ~10 psi w/out a boost controller of any kind, better fuel economy, and a nice exhaust note then i would suggest getting a turbo back exhaust, ive been through a few turbo to manifold gaskets myself, with a custom mandrel bent 2.5" exhaust and none with a 3" so thats my take on it, more pro's then con's

having an sr is a pain in the ass, if it breaks, you gotta wait around for parts, or hopefully its something that as a US equivalent. but for some people (like me) i dont give a shit. i have another car to DD in if my sr needs work, so it doesnt make a difference to me. if you dont know anything about sr's, or turbo cars, stick with a ka.

ps: everyone knows the true ballers run 5' exhuasts on there sr's.

You gotta have 3" or else your gonna blow your gaskets? You pulling bullshiet from NICO again??? Lets do some thinking here...stock Silvias run 2.5" exhaust, I dont hear them randomly blowing manifold gaskets. Check your info before you start spurting random shiet like that. Your popping your gasket because A) Your shiets warped B) You need better engine mounts C) Your exhaust hangers suck.

Size of you exhaust piping has absolutely nothing to do with it.:duh:

To the OP: If your gonna run 2.5 piping, just remember that the straighter the pipes the better and dumb the cat, the cats what causes the most backpressure more than anything.

well like i said ill eventually upgrade...right now i just need a motor in there stat

once done ill upgrade wut i can...not gonna go to crazy ya know

i dunno that cast manifold doesnt warp to easily and neither does the turbo but what would i know ive only seen it happen to everyone i know with an sr including myself, but yes the hangers and mounts dont help the situation either i was just trying to say to avoid further headaches exhaust helps because you want zero backpressure after the turbo, it adds enough as is, also it reduces heat by allowing the gasses to expand, on another note before anything else get rocker arm stoppers because rocker arms actually do come off in those higher rpms despite what others tell you

this is true, after i installed my exhaust, i made 10.8 psi without a boost controller. before it was slightly more than 7psi. it made me happy......:hsdance:
