My small 16g set-up

[Kevin TSI]

Hello there, I recently got back into the DSM game after selling my old talon.

I just got a rust free black 1990 GSX with an awesome condition checker interior and have been stocking up on some parts for it as well as using parts that were on it when purchased.

My plan is just to push the small 16g to its limit and then get a larger turbo afterwards.

Here is my full mods list.

ENGINE AND TRANNY
1..20 6 bolt with wiseco 8:5:1 pistons, Shot peened rods, ARP studs (balance shafts removed and no AC)
2. 3 angle valve job rebuilt head with 272 cams
3.ACT2600 clutch
4.Shep racing #1 & #2 syncros and shift fork

TURBO AND EXHAUST
5. Ported 2g Exhaust manifold with 44mm HKS wastegate dumped of course.
6. Small 16g with Bullseye housing ($270)
------Ported inlet removing the lip (as seen below), j pipe outlet ported to 2"

------Turbine side ported to 7cm and smoothed out all the way to the bottom. Exhaust oulet is also ported to a full 2.5"
7. Tubualr 2.5" O2 housing ($100)
All of the porting is done like this. Smooth as glass. (Had not gone all the way down yet when pic was taken)

8. Full 3" turbo back no cat and dynamax bullet muffler ($120 for piping and muffler)

FUEL
9. -6AN feed from filter and return
10. Aeromotive AFPR
11. Walbro 255lph pump ($20)
12. 650 injectors ($120)

INTAKE
13. 3.5" cold air intake to stock foglight location
14. 34x8x3.5 FMIC like below 2.5" inlet and outlet

15. Full 2.5" intercooler pipes short route straight to D openings near rad
(small 16g clocked so the j pipe oulet is facing downward. J pipe is just the flange with a 2" long 2" diameter section coming off with a 2"-2.5" 90 degree elbow) ($105 in couplers and clamps)
16. MAFT with 3" MAS ($150)
17. Dual type RS bovs (vented) ($70 for both)
18. Port matched intake manifold

COOLING
19. Fluidyne aluminum radiator with (dual 12" 1500cfm slim fans ($44))

TUNING
20. SAFCII
21. Stage 3 EPROM
22. Data Logger
23. HKS turbo timer ($25)

MISC
23. deleted cruise control
24. deleted vaccum lines
25. Dual -8AN breather lines from Valve Cover to catch can (in progress) ($100 in an fittings and lines)
26. NGK wires and plugs

Seems like I am forgetting something but I will figure it out if I did.

Anyways let me know what you think, what you would change, and what you think the car is capable of. I know I hate to bench race but its winter and I can't just get out there and do it for real yet.

And how did you get your holset to look like that? That is very nice work.

 

[Kevin TSI]

Here is the FMIC that I used. I made all of my own pipe.
eBay Motors: CXRacing INTERCOOLER 29x11x3 Civic CRX D-Series B16 B18 (item 390025224964 end time Jan-31-09 15:30:00 PST)

As for the holset I went from 80-3000 grit paper and then used a polishing wheel. I can do a write up if someone would like next time I do one.

Here are the only pics I have of the FMIC piping.

This build is getting real an radiator hoses instead of slip covers.

nice setup. I hope everything works out

Update:

Finished a fuel cooler today which only cost me the fittings.

Put a J- pipe and oil drain on the turbo.

Also here is a shot of some of the parts that are done so far. Tons more on the car.

Also picked up another Greddy RS bov for only $50
Catch can should be don this week except for some of the fittings. Also need to tap my oil cooler.
HKS turbo timer, walbro 255, and intake pipe are on the way.

 

[Kevin TSI]

Put up some prices as well.

 

[Kevin TSI]

Still planning on running dual bov's. Picked this one up today for $50.

Should I run dual type RS's or one TYPE RS and one TYPE S?

Just looking for opinions.

[Kevin TSI]

It was an awesome deal. I may still run the 16g this spring and then switch to the 50 trim mid summer.

 

[talonDSMerr]

You sure know how to find a deal, props. What did you use to port your turbine housing?

 

[90rslaser]

well i had a stock big 16g, and needless to say it took a sh*t at 28psi. hehehe. so i would say u will be fine at about 25 with the small 16g and the work done to it

 

[Kevin TSI]

Got a KN filter today (first thing i've payed full price for)

Going to start on my 4" intake pipe once the turbo arrives.

Also polished my mas while its off. Plus it only took me like 15 minutes.

Got a punishment tubular 02 housing with the turbo.

 

[Kevin TSI]

I used a carbide bit , flapper wheel and finished with a really fine barrel sanding attachment.

 

[Kevin TSI]

Ok I have a little update.

I am going to go with some 880 injectors instead of the 650's.
Using one Type S and one Type RS. (can always change it out)
Been collecting pieces of 2.5" polished aluminum for the intercooler piping. I have everything I need now except the couplers and the IC
Also have been working on a really cool heat shield for the lower pipe out of an old aluminum running board.
Oil cooler is getting tapped for fittings tomorrow.
Shaving and polishing a valve cover. Might just sell this though.
Walbro and an intake pipe get shipped out to me tomorrow.
Planning on 22-25 psi with the 50 trim as well.

I think that's it for now but I will update again soon.

Any opinions or suggestions?

Stick with the Small 16G.

On top of Precision's horrible reliability, their DSM bolt-on turbine housing is so poorly designed that the 16G's tiny TD05H turbine in the Bullseye housing probably flows better than the T31 turbine in Precision's DSM Bolt-On housing. Your current setup will be able to max out the Small 16G compressor at 38 lb/min...the PTE setup would be lucky to peak 44 lb/min (that's the range of a 20G) and will spool much later than the Small 16G.

Regarding your dual BOV idea, read this post in the Holset thread and the responses that follow on pages 18 & 19:

[Kevin TSI]

Well the guy is being kinda shady about the turbo so should I just stick with the 16g? Do you guys think I can still obtain my goals with it and how much do you think I will lose if any by switching to the 50 trim? I am really looking for a quick spool and a nice hard kick in the pants when it does spool with good power through the rpm range.

Also as for the BOV thing goes, mine would be 2389 MM SQUARED if you go by valve size and 1668.125 MM SQUARED if you go by opening size. A tial would be 1962.5 MM SQUARED. Either way it only cost me $70 for both. Find me a tial that cheap and I'll switch them out. haha

 

[yangtech]

Stick with the 16g and when you're sick of it, go get yourself a monster turbo.

 

[Kevin TSI]

Anyone else care to chime in?

50MM BLOW OFF VALVE, XS Power Inc.

I know a guy that's been running one of these on his car for over 2 years with absolutely no issues. It looks, sounds, and performs every bit as good as a real-deal Tial at a fraction of the price. The best part is if something breaks on this valve (diaphragm, etc.), all of it's parts interchange with Tial parts. I'm so convinced with it's success, that I bought one of these to run on my AWD project car.

You could sell those Greddy junkers to a Honda guy on eBay for WAY more than what you paid for them. That would be like getting a Tial for, well....free.

 

[toofast82]

i would like to see you stick with the s16g! Im not a big fan of Precision "quality." If you were to upgrade down the road consider something more durable like mhi 20g or holsets

 

[Kevin TSI]

Sticking it out with the 16g.

Bovs are for sale in the classifieds. And no i am not selling them for what I paid for them. haha

 

[Kevin TSI]

A little update.

Got a TIAL 50mm today. I love it.



Also I am still going to get the 50 trim. Its just too good of a deal to pass up. But I will be running the 16g first.

 

[JusMX141]

NICE BOV CHOICE! Looks identical to the one I bought, only mine's missing the "TiAL" engravement on the top...which you'll never see anyway because of the placement of the valve.

 

[Nihad]

Parts look good keep it coming..
