Buy cheap, buy twice. Comparing a Chinese turbo to a Blouch isn't a fair comparison IMO.

 

Yes, 850cc is plenty on pump gas though I'd convert to top-feeds if you can. The Bosch EV14 injectors available from ID and DW are awesome, drive like stock. Modded ones, not so much.

Whatever you do dont purchase a BNR turbo. Id recommend an FP turbo/green specifically. Id stay away from the chinese knockoffs like was previously mentioned. Too much of a gamble when you are spending so much money. Do it right the first time and you will be much happier in the end. Good luck and welcome!

[krush]

Yeah, you guys are very persuasive bad influences. I do have the winter to prepare for everything. When you're spending 1000+ on a good turbo, what's another 600ish for an awesome turbo? So I guess the question now is which medium sized turbo for the ultimate in quick spool? I was doing some reading on the 1.5 xtr and it seems like you need the holy header or a replica of it in order for that turbo to really shine. Is the FP green superior if you're on UEL headers? I think I might not be as happy with EL headers. I love the rumble.

[fahr_side]

The rumble is also known as the sound of slow.

 

People who's opinion I trust have said the Dom is laggy on the stock header. My own car picked up 20whp just on a BNR 16G by adding an equal length header. I'm using the same Tomei header with the Dom and while it's not as bling as the KB part it works very well.

 

Another consideration is an intake. You're fine on the stocker with an 18G but the Dom will find it restrictive if not max it out altogether.

 

I'm going to say again that boost does not accelerate the car. Torque does. Do not get caught up in which turbo hits x manifold pressure at the lowest rpm. Look at the revs at which (say) 250lbft is available instead, it's much more useful information.

 

Do not use a 7cm2 exhaust housing on an EJ25x unless you want a spiky torque 'curve' like a turbo diesel.

 

Note that MHI never made an 8cm2 housing for a TD05 on Subaru flanges. The only one available back in the day was the Greddy T18Z item and that is what Taiwanese vendors like Kamak and Zage copied, and those were copied in turn in China. The geometry really isn't that great. Many US specialist turbo shops just buy those housings in, faults and all, because tooling is expensive and the volume isn't there. Poor housing geometry increases lag and limits power potential. This is one reason I like the Blouch 18G. Their housings are very well engineered.

 

If you are not chasing big numbers and want good spool and response on a budget you could do worse than a takeoff VF-48. While IHI aero and bearing design is dated, the 7.5cm2 P18 exhaust housing is very good. Snappy feel like an MHI 7cm2 with less of a choked feel at high rpm. I'd choose this every time over a Chinese eBay knockoff of a Taiwanese copy of a 20yo Greddy tuner turbo. Note that Tomioka, Tomei etc. all use the same parts they source from suppliers like Kamak, made in China. I don't know if BNR still uses genuine MHI parts but he certainly used to.

 

tl;dr: If you're paying $1,000 or less for an 'MHI' turbo it was almost certainly made in China and if it has an 8cm2 housing it's shit.

I understand that UEL headers hold back some power. I'm not dead set on using them. I'd never pay the price for Killer B headers, but may consider a Perrin (still stupid money) or CNT or some other "knockoff" EL headers. The only Killer B parts I plan on for this car are the pickup, baffle and pan combo. I'm not trying so set any power records with this thing, I just want a nice driving car that will perform when I ask it to. When you say intake are you referring to the intake manifold itself? Is the STi manifold that much better? I think my turbo selection is now between the Blouch TD05 18g 8cm XTR or the Dom 1.5 8cm XTR. I see so many different opinions and experiences with different turbos that it makes my head spin, but these both seem to be very good performing units with no real complaints.

[fahr_side]

I meant the pipe with the air filter on the end. I'm running an STi alloy manifold simply because I wanted to run an STi-style turbo, stay TMIC and avoid the extra hose and bends the aftermarket solutions for the plastic manifold need.

 

The Dom is just $100 more than the 18G XTR. Difference in response is in the realm of noise, but the Dom will kill it at high revs.

 

Between the overpriced Perrin and the cheap and nasty CNT etc. is the Tomei / GTSpec header. Works and fits great. I've had mine four or five years and no sign of it cracking.

[battelready]

Keep in mind you can always pick up used things as well. I picked up used tomei el headers which were already ceramic coated for 250. Just keep surfing the lgt forums and naisoc.

Yes, I plan on doing an intake and air inlet at the same time. I think you may have talked me into the Dom 1.5 xtr 8 cm. Most people I see are running the ID1000 injectors. Is that not overkill for 93 and my intended use? I have read that they still perform better (for the tuners) detuned than most other smaller injectors would in the same situation. I'll have a very safe tune on this car from Brentuning when it's all together. So far my list consists of:IAG Stage 1 shortblock, Killer B pickup, baffle and pan, Blouch Dom 1.5 XTR, ID1000 injectors, rebuilt heads (not sure where yet), TGV deletes (not sure which yet), ARP head studs, new oil cooler, new clutch & flywheel (not sure which yet), Cobb AP, Intake (not sure which yet), air inlet (not sure which yet), turboback (not sure which yet), Racer-X FMIC. Anything I'm forgetting? Gauges. Probably oil pressure, EGT and boost. Any recommendations for any parts I'm not sure on yet?

[krush]

We're not scared of used parts either! My husband is almost finished on a budget EJ25D/EJ20K TD04 frankenstein build right now. Most parts are used factory parts from other cars. It's all being squeezed into a 97 OBS right now actually. No $120 used turbo going on my Legacy though!

[fahr_side]

ID850s should be enough on 93 but ID1000s are not stupidly large. I usually like to use the smaller injectors because they are more linear at low IPW and therefore driveability is easier to tune just so. If there's any possibility you will use E85 in future, get the bigger squirters. These Bosch EV14 injectors are so much nicer to work with than the modified stock injectors like the old Deatschwerks stuff... much smoother in use, better idle, better tip-in, better economy.

[krush]

Unfortunately, the closest E85 is about an hour away. So it will be running on 93 for the forseeable future. Our 93 around here all says "contains up to 10% ethanol" on the pumps. Would that variation be tricky to tune for? Because we also have ethanol free 91 available at certain stations in the area for consistency. I usually run the Shell V-Power 93 with some ethanol in it and all of our other vehicles seem to like it. I think 850s would make more sense to me. I can't see myself using the 1000s even close to their potential. Thanks for all the advice everyone!

[fahr_side]

10% ethanol is about 4% difference in fueling. I'd want to scale the injectors for E10 but tune timing for straight gas. Remember that Shell call whatever the best gas they sell in that market as 'V-Power', regardless of what it actually is. I wish there were a button you could push and all marketing people would fall down dead.

[Mike07LGT]

As far as your clutch setup goes, you should really consider southbend. Im running the stage 1 in my car and its been great so far. Also any reason why you want a FMIC? Might wanna do some more research on this debate.

[krush]

I want a FMIC primarily so I can run the flat hood, but I don't think it will have a negative effect with the Dom 1.5. If it does, I'll gladly accept the negligible loss in performance. Southbend seems to be a good bet. Pretty sure that's what we'll be running in our Powerstroke truck. I was also looking at the Competition Clutch steelback brass plus with flywheel kit. It seems to be pretty well liked and is priced pretty well.

Very interested in where this goes....

Which part? The Dom 1.5 with a front mount or the clutch? Any actual progress on this car will take place in the spring. There's a Ford Ranger and a Samurai in line before this car sees any new parts.
