so today i decided to put an evo9 turbo on my friends 240sx with an s15 sr20. i worked on it for like 30min today. made one collector. the sr turbos suck and its slow. so we decided on the 9 turbo because i had a flange and turbo laying around. i want the manifold done by the end of this weekend. lets see

 

oh this is getting interesting. by saying they "suck" what exactly do you mean? the s15 turbo is ball bearing with inconel turbine aka "ni resist" so i dont see how this could suck.
id like to see some dyno graphs once this is done

its nice to see some sr20 love on here keep it up!

 

the car currently has a s14 turbo on it and a 5 speed tranny because the tranny and the s15 turbo went bad. reverse went out on the 6spd tranny

 

you mind as well just go t3...

 

he said he had the parts lying around, so why not?

but there isn't much fab work there yet...post more pics!

 

i have alot of pics i need to put up. we decided to take the head off and change the headgasket. the collector is made. but seriously this is going to be a hard manifold to make. i cant wait till its done and on the road. i have to modify the o2 housing too. ill post pics tomorrow.

 

i hope youre not going to make a tubi manifold for a stock turbo... make a simple log for quick spool and later if he upgrades then make whatever you want.. unless he wants to be limited to DSM flanged turbos.

nice 30min of fab lol.. dont brush ur welds man, we NEED to see COLORZZ!!!2

edit: forgot you made a collector.. and tha flange doesnt look like it'd go flat on a log. make a mini ram?

 

The turbo's are twin scroll, so your better off working with this. You'll get 400+ out of that turbo, so there not that bad!

we decided to change the headgasket. we also went with an evo8 turbo

 

we still have to polish and weld the pipes

 

looks good , I see someone got a lil to happy with the orange rtv :p

 

LOL yeah the owner of the car loves his RTV. he'll clean it all tomorrow from everywhere and i'll take a new picture lol

 

i love the black intercooler pipes and intake!

exhaust manifold looks great! cant wait to see it finished

just noticed, does he run a map sensor? what ecu if i may ask?

 

It is hard to tell from that pic but are the runners paired up right , cycl 1,4 to one side of the turbo inlet and cycl 2,3 to the other ?

 

all the runners are welded this is an old pic

 

The manifold runners are paired incorrectly..

 

I'd just noticed this also.

 

you need to figure out to rotate each runner clockwise to the next position on the collector and you should be able to fix it with minimal work/material.

edit: i just went back and read this. that sucks!

 

looooooooool @ runner pairing.. how could you not notice when youre making a devided mani?

 

Not noticing and not knowing are two different things.

 

Dannyboy, take that pic down or fix it! LOL

 

people have been asking about that on evom, he hasnt responded so im guessing he's fixing it

 

or he is too embarrassed to return.
