The start of an sr20 with an evo9 turbo

[S14_Kouki]

So we are building a turbo kit for a evo9 turbo on a SR20. This is a s15 sr w/ s14 5 speed with built head. Im using the the stock rods and pistons with all new acl bearings, balanced crank,new rings, hot tank, hone, .10 deck. Here are some pics of the progress. You can follow the build with alot more pics and info at Fabthis.com

Looking good man. I've seen people claimed that they'll try to get the EVO turbo work with the SR/KA but none went through with it.

I'm anticipating the dyno.

[jamg]

what is the evo turbo?

20g?

[gabe30]

umm "manifold on the car" picture is the same as "manifold almost done". your car has a sink?

[S14_Kouki]

The evo turbo is a 16g ppl r making over 400whp with lots of boost and race gas. So im going to run 26 psi and see what it makes :) yea the manifold is done ill take a pic of it off the car tomm. I was just putting up pics in order of how its been going together. Iv never seen a twin scroll evo set up on a SR nor a KA ether so we will see how it works. gabe30 what dp u mean by sink?? thank u for the good comments

sorry i fixed it. we still have some cleaning of wires and stuff so it will look better.

haha no because your photo when it was misposted read "manifold on the car" when it was "manifold almost done." that picture is on your counter top and the faucets right there. you must have a sweet ride.

[S14_Kouki]

lmao ok i got u with the sink. Here is a simple list on the engine. I am running a power fc, the head is built tomei pro cams, bc springs,bc retainers, rocker arm stoppers, all brand new seals, apex HG, acl bearings main, rod, and thrust, new oil pump, new rings, hone, hot tank, deck thats off the top of my end. Im using stock rods and pistons.

I remember this car on honda tech where they mentioned the manifold design sucked and you haven't posted back in that thread since LOL!

the start of an sr20 with an evo9 turbo - Honda-Tech (http://www.honda-tech.com/showthread.php?t=2605878)

[flip3d]

^^ lol they're right though.

[Slip&Sliden 240]

This turbo twin scroll is pretty nice on a SR. DSG had an evo 6.5 on his car for awhile. Im also running an evo9 16g on my sr with a power FC d-jetro. I never have taken to the dyno yet.


here is a pic for motovation

[S14_Kouki]

yes sir its on honda tech I personal did not make that thread on there so I dont know whats on going on honda tech lol. but yes there has been talk about pairing the runnings and u can see they are not paired. You can see the pic above me he has RHD so he has alot more room to work with. You cant pair the runners with a bottom mount and I dont want a top mount. Its all good im sure its still going to make good numbers and be really fun. thank u

[S14_Kouki]

Yes I will be keeping PS as for the AC I have never had AC in the car so I dont know if the set up will clear everything for AC. Ill have pics up tomm of the intake im not 100% sure how I want to run the intake yet. Im sure that we could have paired the runners but as u were saying the extra piping in return longer runner effect the spool time. I dont think that the runners would be as equal length as they r now if we did pair the runners as well. idk its done now so we wont know till I fab up a different style evo SR manifold. The project is coming closer to being finished.enjoy :)

Here is my sweet ass relocation bracket

What the hell is Honda tech? anyway that manifold looks tite to me.

[viperbite]

very impressive :)

you have power steering.

now make a/c work!!! :P

[silnismo]

Twin Scroll FTW!

Those welds are SOOO nice.

[S-Nation S13]

keep up the good work dont mind the hate..lol there hating while you actually doing it .. DO WORK!!!!!

[Slip&Sliden 240]

I dont think that the runners would be as equal length as they r now if we did pair the runners as well. idk its done now so we wont know till I fab up a different style evo SR manifold.

The idea of twin-scroll is to seperate the exhaust pulses. That is why cylinders 1 and 4 get paired together while 2 and 3 pair together. Basicly you are eliminating the twin-scroll effect with incorrect pairing. Longer runners can produce more bottom end. The dent sport 240maxi had extremly long runners on his 16g setup. If I remember it was something like 320ish hp and 360tq.

Not hating on your setup just clarifying a couple of things.

[civilized_drifter]

those welds are beautiful man

[S14_Kouki]

Thank u all for the props. Yea im going to experiment im going to build another manifold after im done with this one so we can see the difference in a paired manifold and non paired.Yes the haters out there will hate but as u say there the ones watching me build my car. ill have pics up soon.

Fabthis.com

[burnsauto]

yeah what is your setup for the TIG action thats going on in those welds.

Gas mixture?
Fill rod size/type
Amps?
Post flow setting?

..and what kind of welder?

[S14_Kouki]

Miller dynasty 200dx
100% argon
i used 1/16 316 rod and 1/16 309 on the flange "since its mild to stainless"
amps i did like a 120 on the runners like 85 on the DP and like 140 on the flange
post flow before the arc is 2 sec's and after is 9 sec's

Yes the haters out there will hate but as u say there the ones watching me build my car.
I'd rather live in a house built correctly than a house not built correctly. But since you're rich and can afford to waste metal and time then by all means playa go for it.

But I "HATE" when people use "hating" as an excuse for your lack of engineering experience and instead of explaining why you did it that way rather than patting yourself on the back for making a manifold that eliminates the primary use for the turbo when you could've just threw a t3/t4 on there instead.

And any ignorant dipshit stupid enough to say I'm hating because you're doing it wrong is just as much as an idiot as yourself.

So yes I will laugh at you, building your car sir.

I build shit too so sorry if I'm not impressed.

[D.Bo]

i might be wrong but the runners on the manifold look like they're routed wrong. looks like 1.2 on one side and 3.4 on the other side. shouldnt it be 1.3 and 2.4?

[twisties]

mmmmmmmmmmmmm nice mani

[S14_Kouki]

Om1kron
Thats cool im not out to impress you. I didint have the room to work with. There is no sense in putting in retard sharp bends to pair the runners, it would be redundant, think. Yep super engineer . That was 1 of many reasons for bottom mount including angle of the wastegate, not having to buy new intercooler piping, dump tube design, not boiling my BMC, etc. Thats cool u build stuff yourself if u want to talk trash how about u build one and show me the right way if your super smart. The whole reason im doing this is so I dont have to do a t3/t4 like every other SR in the world. Do not worry im going to make another one with paired runners to see the difference.

[GabeS14]

I love custom work, but curious why you would do all this work for a turbo sooo small, i mean it would be much easier to just get a 2871r and get the same or a 30r and get even higher numbers..
is it just to do something different, or because thats the turbo you happened to have at the tme or what..
just curious, no hate or anything..

[S14_Kouki]

yes my buddy upgraded his evo so he had that one laying around. Another thing is I of course what to do something different every SR runs a 2871 or a 30r so I thought it would be cool to see what a evo turbo would do im sure theres ppl out there that would like to see the numbers. I built my manifold and DP for cheaper then buying a used 2871 so maybe ppl out there want a different way to get alittle more power then buying a 2871.

cool thanks.. good luck with the build..lets see those numbers

[clark]

lol how can anyone talk trash about what OP is doing. this is awesome

[ixfxi]

looks really cool

i like the welding. i may not know much about the manifold design, but i dont think that matters.. because your dyno results will either impress people and make them suck your cock, or......... you'll just redesign a better one.


with welding skills like that, you sure get my respect. nice work.

mike / clearcorners.com

[S14_Kouki]

^ thank u ^ Iv been welding for a couple years now. ill be starting it tomm I was going to tonight but theres kids sleeping and I dont want everyone to wake up but there will be vid tomm and I get to start tuning.

I will say that unless it's been tested, I have some doubts as to whether the traditional 1-3 and 2-4 pairing is the best. You might get a little more turbine inlet pressure at the expense of more pressure in the port due to grouping the pulses together. Might make a little more spool in return for more backpressure at high RPM.

Just my 2 cents on all the "hating" here...

[fromxtor]

I've never seen a twin scroll evo set up on a SR nor a KA ether so we will see how it works.

Well here are some pics, now you cant say you have never seen one. ;)

Traditional pairing is 1-4 and 2-3. It has been shown that a correctly built twin scroll set up will spool faster then a single scroll set up.

i'm pretty sure he was talking about a twin scroll 16g set up...... everyone know full race makes a awesome twin scroll manifold, and power lab


i'm really diggin this thread.... i drool every time i look at the welds... def looking forward to seeing the dyno numbers and where th boost kicks in....

mad kudos for going out and making you own shit.... so baller

[s14unimog]

Not only shown, Proven. If you inspect the factory SR20 manifold you will find that is exactly how it is constructed; although the turbo is single scroll. One thing to consider though with a custom manifold, is the length of the runners. If you go for equal length, or even larger runners, you'll see a trade off with spool time and peak power numbers. I think its great, that you undertook this challenge, but why? I worry that the culmination of your efforts will yeild a slight gain if any, over a more traditional setup with shorter runners. None the less, I still think you have amazing fabrication skills. Good job; I wait for your result.

A question for anyone, are there not any other twinscroll turbos that utilize a smaller collector? If the Evo's turbo wasn't so awkward to fit, I think you would see more people running them.

I know what is traditional, and I know what a twin scroll can do vs. a single scroll.

I just wonder what the sensitivity of power due to increased VE vs. "spool gains" are with the 1-3/2-4 vs. 1-2/3-4 pairing.

When you think about it, the later has pulses coming in the most evenly, since the firing order is 1, 3, 2, 4.

[S14_Kouki]

Thank u all for the good replies. And its all done now full spool at 18 psi is at 3700 rpms thats not to bad. Im still just slowing tuning it just glad to have not s14 back on the road. I have not turned the boost to 26 psi I plan on that this weekend. It pulls really really smooth no dyno yet sorry well here r some finished pics. And I promise ill have a vid at 26psi this weekend. PS the pic of the s13 w/ ka bigass turbo does not look like the distributor with clear the turbo.

Answer: look into the 2009 mini cooper. those little suckers are twin scroll and make stock sr numbers out of a bone stock 1.6!!

[chituntang]

Are we still thinking SR, an engine that is produced almost 20 years ago, will have a better number than a performance engine today? Hell, K20 makes 220 horses, yet it is only a 2.0L NA.

But to the OP, lets make a "twin scroll" manifold now.

[S14_Kouki]

If u want to get tech my engine is a 01 so not even close to 20 years old. Yes the twin scroll will come soon I have some other projects tho I have to finish first before I take my car apart again to make a new jig for the new manifold. I should have some vids up tonight I will be retuning my boost cont tonight for 26psi.

bump, whatever happened to this!?

[90hatchie]

i bought it
ran it and sold it
the twin scroll was made wrong
it was a pain in the dick to install too
friend in NH has it now

[dorkjoey240]

man sick set up. :)

[97SerevoSX]

Ahh, what kind of power were you able to get out of it? Even made poorly it should have made some good power, just not spool well

[mewantkouki]

This car is long dead. lol
