Finally got around to snapping a few pictures of my project out here in Bangkok.
Check out the Blog for details and a little write up. Flex Fuel SR20det swap BMW E30 (http://brewedmotors.com/blog/brewed-thailand-bmw-e30-sr20det-powered-circuit-toy.html)

I will try and keep it to mostly pictures and video here on the forum ;) Of course please feel free to ask any questions, always happy to help out if possible.

Super short build list: BIG thanks to Alex at Brewed Motorsports (www.BrewedMotors.com) for getting all my parts safely shipped in one package to Thailand!

Coming from the states where i have every tool imaginable at my finger tips this little project is tacking me back to my roots!

https://lh5.googleusercontent.com/-I-hnTRpqsGs/T31t49-8VdI/AAAAAAAABTE/3au0tqf9LOw/s640/Brewed_sr20_bmw_swap.JPG

I am still waiting on most of the parts to get this thing finished up and on the road. But here are a couple things that have already arrived ;) The Big package of electronics and fuel parts from Brewed should be arriving in about 5 days. Just hope customs doesn't rape me on this one!

[rgztmalv]

Looks like it's gonna be a pretty sick project.

25-30psi on an S15 turbo?

[ralphandthequeen]

i miss Thailand.. so much fun. and looks like a nice ride. keep updating!

[tunermt]

25-30psi on an S15 turbo?

It will make the boost and good power in the mid range however I will need to taper the boost down to ~20 by redline.
(this set up makes for a FAT torque curve on a little SR20, very nice for sliding)

Oh and a pic of the wheels i'm leaning towards at the moment, 16x9 20mm will more than likely still need some spacers though.

[onehundredoctane]

Do work eric!

[jr_ss]

I'd request this get moved otherwise lock down I foresee... A lot of people swapping SR's into BMW's lately.

[keeeban]

the things I would do to have a place like that.

[tunermt]

Thanks for the kind words guys, i was planning to have some updates and be driving a bit by now but BC Sports Thailand just told me yet another few days until my 51mm front lower coilover mounts clear customs...

[tunermt]

Well the post office finally got me the big box of treats Brewed Motors sent out 2 months ago!

Just yanked out the S14 SR engine harness and started labeling/cleaning things up in preparation for the AEM EMS install and tuning.
Pictures of the finished harness coming soon.

All cleaned up ;)

[KravingAKouki]

the things I would do to have a place like that.

haha yea i totally agree. but if i had a place that big id want a lift knowing id have the room. jacks and jack stands are such a pita sometimes

[tunermt]

Haha the car was on jack stands 10ft I'm front of a lift that no longer worked. That shop is about 300 meters from my apartment and was a body shop that closed after the terrible floods out here last year. The owner is super nice and offered me space to tinker with the car until the new location in Bangkok is ready.

[future]

So a s15 can do 25-30lbs now? Thats something new

[Sileighty_85]

It will make the boost and good power in the mid range however I will need to taper the boost down to ~20 by redline.
(this set up makes for a FAT torque curve on a little SR20, very nice for sliding)

http://www.bmwsociety.com/classifieds/images/221149.JPG

I would like vids of a OEM S15 T28 boosting 30psi.

Then an update of said turbo after 3 events.

[tunermt]

remember my friends 25-30psi will only be in the mid range, to remain "safe" tapering the boost back down to the 20psi range by red line is a must.

For example (RUFF example don't quote these #s they are just an example, stock SR with S15 turbo) at say 4500 rpm and 20psi the shaft speed would be ~100k rpm but by 7k eng rpm and 20psi the shaft speed will increase to ~130k rpm (engine is moving more air the turbo must work harder to keep up)

At 4500 eng rpm and ~28psi the shaft speed will be ~130k rpm, by tapering the boost back down to ~20psi by 7k eng rpm you can maintain a similar/safe shaft speed. As apposed to forcing ~28psi at 7k eng rpm causing the shaft speed to sky rocket to 150-200K rpm + of course trying to hold to much boost all the way to redline with a small turbo will also cause intake temps to sky rocket ;)

Don't get me wrong this is not easy on a turbo but if you keep a close eye on everything and don't get greedy it is a great way to make some extra torque as long as your fuel can support it. (high octane to avoid detonation)
Unfortunately i will not have a shaft speed sensor on this turbo to show you all exact #s but this should give you an idea.
I will however be happy to post up AIT, boost, rpm data to help shed some light on this.

Don't get me wrong this is not gods gift to tuning small turbos but it does work quite well its just a matter of finding the "sweet spot" which very well may be 25psi tapered to 18psi.

haha notice i did say 25-30 yet 30 is the only # anyone repeats ;)

[Sileighty_85]

I dont know if you know something we dont know, but the max power and boost that turbo can put out safely and reliable is 300ish hp at 16psi.

anything past 16 is past its efficient range and it will grenade. I know this because Ive had friends that have been tuned and ran that turbo at 18-19 psi and the bearings shit themselves. then another one that his boost controller crapped out and was running 21-23 psi and after a 3 weeks was a substantial increase in shaft play.

[future]

Yeah there is no way it will make that much boost.

[cbcm2435]

i trust that eric knows what he is talking about. he tuned my car, and i run 18-19psi on my t28 daily for probably 6-7 months now, including a 1500 mile trip when i moved to PA. and i checked my turbo the other day while i had it off and its still good to go.

[Sileighty_85]

i trust that eric knows what he is talking about. he tuned my car, and i run 18-19psi on my t28 daily for probably 6-7 months now, including a 1500 mile trip when i moved to PA. and i checked my turbo the other day while i had it off and its still good to go.

DD and 1500 mile trips don't mean anything, you're not straining that turbo driving at 2,000 RPM in Vac, unless your running full boost the whole way.

Drifting/tracking a is different story.

[tunermt]

No worries guys i'll post up details and results, haha i'll be throwing some anti lag at this turbo as well to help make sure it lasts forever ;)

[tunermt]

Couldn't find an electric shop ANYWHERE in my area (near Bangkok) that had what i needed... or even understood what i needed haha, SO I cannibalized the old gauge cluster i wont be using.
Didn't find the 100 ohm resister that i needed but i did score a 70 ohm and a 30 ohm bing bang boom soldered inline =100 ohm resister!

http://a1.sphotos.ak.fbcdn.net/hphotos-ak-snc7/314083_10151004367066553_985555989_n.jpg

[onehundredoctane]

Is the resistor added to calibrate the speedo?

[tunermt]

no i pulled the resistors out of the old BMW gauge cluster (my dash will consist of 1 AEM serial gauge, shift/rpm lights and MAYBE a tach)

The Alternator has power, ground, and a 2 pin connector (voltage sensor wire and the wire that runs to the dash warning light).
I don't have the nissan dash or warning light/led from the dash so i had to use a 100 ohm resistor for this wire before the Alt would start to put out any voltage.

[tunermt]

So preliminary tuning, just giving the map a bit more head room for some extra boost and RPM :)

Was planning to finish up the front half of the chassis wiring harness today but to damn busy with a few E-Tunes.

[tunermt]

Fuse box and start switch all wired in and mounted on top of a little sticker bomb action ;)

pulled apart the front half of the chassis harness to make sure the engine bay won't be cluttered up by anything i don't want to look at haha

Coming along nicely Eric. The wiring harness looks top notch.

[tunermt]

spending far to much time wiring these days, here's a pic from the Buddy Club Thailand DC5 i just finished up.

[g00se]

Dope build! I was just given a e30 (barely running) and was wondering if you are running custom mounts? I am thinking of throwing my KA into it as it was leftover from my ls1 swap.

I was looking at these sr20 ebay mounts for the e30 but they look pretty shoddy.

[drscooper]

dam that is great stuff man! keep up the good work!!

[tunermt]

Ya custom mounts, shoot me a pm I could easily whip up another set of nice tig welded mounts.

[g00se]

Down thanks! How are you planning on wiring it? are you keeping the stock gauges?

[tunermt]

My dash will just consist on an aem serial gauge and possibly a couple shift/rpm reference lights. I will throw a tach in if I stumble upon the right one.

[mpact1981]

just seeing the word "Thailand" in the title instantly brought back memories... lol

Nice build! Be careful driving on those streets though. Craziest drivers I've ever seen in my life around there

[Kingbaby]

Subscribed. Missing Bangkok so much!

[tunermt]

haha yes Thailand is a damn fun place to be.

[Kriskouki]

Wow......I am subscribed to this build.......

[tunermt]

update will be coming soon, i need to get my slide on! Been crazy busy with the DC5 circuit car just pulled a 24 hour track prep day, corner balanced, bit more wiring of accessories and new gadgets, fuel system, aero, fallowed by some dyno tuning. On the way to the track now for the real testing :)

[eldine30]

this is awesome man, i wish i could finish my e30 sr20 project. :/

i have a e30 sr20 FOR SALE ready custom Chasebay wiring harness e30 to sr20det READY! plug and play they did a great job.

also have custom motor mounts, tranny mounts and driveshaft and a redtop sr20 complete swap with a 2door shell FS

[tunermt]

Tie rod spacers almost finished up.

very nice!

and pardon the noob question, what brings you to thailand? stationed?

[tunermt]

I wanted to live here and build race cars so here I am ;) haha.
(note i am not refering to my e30, my e30 is NO race car)

[tunermt]

Removed a good portion of the front chassis, looking forward to taking delivery of my Ar. gas this week to get my weld on!

More metal...

Front strut towers
Tubes to front frame rail
Tubes to lower frame rail under drivers/passengers feet. *still need to add gussets to a few places on these*
Repair/re-enforce/replace frame rails
Added "sub frame connectors (these basically run wheel to wheel (front to back) along the pinch welds and have a few cross bars) *will be incorporating trans mount and drive shaft hoop in the cross bars*
Sheet metal patch/re-enforcement **as you can see in the pictures rear of the front wheel wells still need some sheet metallove**

[s13silvia123]

you're in Thailand, you aren't you near any floods from the monsoon?

[tunermt]

Monsoon did not effect Thailand that much (not in the path of the storm). It is rainy season though and ya Bangkok is built on a swamp at sea level so it does flood often in many areas around the city.

AHHH i was gifted an EVO 8 turbo from a friend and built a manifold for it instead of the T28. (I prefer the twin scroll housing on the Mitsu turbo for this particular build so the free turbo was hard to say no to).

Little teaser of the AEM CD5 dash, i'll get some more detailed videos to show off all the custom dash designs i've been working on for the little SR20 in this thing.
