Cool taking the turbo plunge

Thats right, this comming Friday I will be heading up to Mile High Automotive in Prescott, AZ to have Robert install a T3 turbo kit into my SVX. 5lbs kit.

I can't wait.

Details, please. Why only 5 lbs? IIRC Imprezas have gone to 10lbs on stock internals. And if an Impreza gets a 25% boost from a turbo, that would put your SVX at about 300hp, right? Wrong?

It's like this. Robert was cutting me a GREAT deal on his old T3 setup. And he suggested not going to higher in Phoenix than 5lbs due to the summer time heat (110 plus daily) without having an intercooler.

OK. So... why no intercooler? Like, without an intercooler, what's the point of having a turbo?

Higher air pressure = more power, but higher heat = less power. You are not using the setup that was posted here a while back are you? An intercooler is a must!! Surely a water to air intercooler could be rigged or something.

Could be yes, will it be right off the bat, no... I just don't have the funds for an intercooler at this time. That being said, you don't necessarily have to use a intercooler upto / including 5lbs. IIRC, you really need to use an intercooler from 7lbs and up.

If only I had more money.... If I did, I would be getting a turbo for my MY00 Impreza instead...

Good luck with the turbo! Please post pictures and try to get out to a drag strip and give us some good 1/4 mile times! I'm interested to see how much of an improvement it'll actually give.

I priced some turbo setups at International Motorsports Products "the best in the North-East" in Clifton, NJ. They would locate a single turbo in the same place as the one you guys are talking about.

They told me it would cost $5000 for a single NON-INTERCOOLED turbo (up to 10psi or so), and $7500 for the same turbo WITH an intercooler (probably the dual split 300zx intercooler, since we have the two open spaces in front of the wheelwells).

I then asked about TWIN TURBOES, and they said it would probably take at least 2 months to build, and $15,000-$20,000. They said it would be a "ONE OF A KIND DREAM SETUP." The only one of it's kind in the ENTIRE world. 500 to 600+ hp. EVERYTHING in the engine would be BUILT UP, cryogenically treated and coated with ceramics.

Well I just spent close to $4000 on a SUPER HEAVY DUTY transmission rebuild. So I didn't quite have the money for either turbo setup. Maybe sometime in the future I will be able to first try out nitrous and or a single turbo, and build my way up.

For now I have to let you guys with deeper car fund pockets try out stuff like that. I do know though, that when I finally am ready to do it, I'm gonna have a GREAT job done!

Enjoy!
Eric

I think Robert is working on a twin turbo setup as well, but at quite a lot less. More like under $5k. More as it comes... Man, I got to get Robert posting on here more often....

There are several reasons to stay at 5 lbs of boost. One of the best is the SVX has a higher compression engine than a car designed as a turbo from the groundup. For example my turbo Legacy is lower compression and has a system to oil the pistons. Another is the fact that the ECU is able to run stock with 5 lbs of boost. If you raise the boost you may need lots of add on widgets to keep the car from detonation. Believe me a six cylinder car that already has 235 hp
N/A doesn't need higher boost pressures as much as a 4 cylinder USA spec Impreza.

Exactly my thoughts. The SVX already delivers 230hp....a conservative 5lbs easily takes it to STi WRX 280hp levels!

Sure you'll get up to WRX power levels, but the SVX WEIGHS 1100 lbs MORE! It'll be a fun GT, but the SVX has the potential to play with the BEST exotic supercars in the world!

Alright so I guess 5psi of boost is good for an entry level turbocharging setup. Seems like there is a good, comfortable, conservative, bufferzone that SVX's stock setup has, which allows for moderate boosting.

I just point out the OTHER flat six out on the market. The 911 TURBO is getting over 400 hp STOCK. RUF modified 911's get 500-600 hp, and go over 200mph!!

Someone just HAS to get an SVX up to that level to play around with them!

It would make EVERY magazine, possibly on the cover of every magazine!

You could do it for about $20,000, which is MUCH cheaper than a $120,000 911 TURBO!

Getting similar results while keeping $100,000 in your pockets makes sense to me, what about you??

Eric
PS Oh and the 4EAT can be a lot of fun too, if you understand how to get the MOST out of it!

Maybe in the future I'll step up and get the intercooler and T4 kit, but I think that will end up on the Impreza instead.

Look out Rustangs and Camaros....

Question

$20,000 to turbocharge an SVX is a bit steep. I would be suprised if it cost more than $3,000-

Replace the pistons, add some electronics, uprated fuel injectors, a water to air intercooler (not much space under the hood).

It doesn't cost $20,000 to turbocharge a Maxima, for that price you could buy a NEW WRX engine, mod the S#!T out of it, swap it into your SVX engine bay and still have plenty of cash left over for the custom 5-speed transmission conversion, plus dyno time to tune it all.

$20,000? Please, let go of my leg.

Question

If $20,000 is too much for a TOTAL DREAM setup, then tell my why the McLaren F1 EXHAUST SYSTEM ALONE is $18,000?? (think about that the next time you complain how much your muffler costs!)

I'm not talking about going up against "Rustangs and Camaros." I'm talking about going up, and mounting a serious campaign against the FASTEST EXOTIC SUPERCARS IN THE WORLD!

$20,000 is NOT a lot of money, it can go pretty fast, if you price all the components and labor costs. This would be a refined and developed system, not some budget scrappy race setup. When I asked about it, I told him I was interested in a BI-TURBO setup. Where one turbo is small, and the other one is large. The small one makes boost at lower RPMS when exhaust pressure is lower, then when the RPMS climb (along with exhaust pressures) the larger turbo takes over and REALLY starts PUSHING!! It's a complex setup to handle and fabricate all the piping and mounting, but end results would make a FORMIDABLE powerplant! With that complexity comes a high cost.

This type of setup would stay with the theme of the stock SVX engine setup which has a GOOD amount of USABLE torque throughout the ENTIRE power band! You won't need a 5 or 6 speed manual transmission, when you have such a deep and wide power band. 5 and 6 speeds are needed on PEAKIER engines (such as the 2.0L flat 4 WRX) when you need to keep the revs in a certain (high) range to make power. Anyway, because the torque converter in the 4EAT has the ability to lock and unlock, we essentially have AN 8 SPEED TRANSMISSION! Plus when configured properly, I think the TRANSMISSION CONTROL UNIT can shift MUCH better than any driver ever could!

For $20,000, I'm not just talking engine mods, I'm talking about a COMPLETE SYSTEM. Suspension, Brakes (BIG ONES), Wheels, Tires, exhaust, transmission, differentials, Frame/stabilizer/strut/sway bars, Custom Radiators, Intercoolers, etc etc! Who knows? $20,000 might not be enough!!

In order to rival a $120,000+ car, I'd say that $20,000 would be the minimum entry fee! You should see the budgets of most of the "refined" cars in the magazines. I'm sure they're about the same!

I'm sorry, but don't pull your own leg! The business of SPEED is NOT cheap!

I must concur with Eric. We aren't talking racing the Civics or Foci. My aunt's SVX is fast already, with a TT, it could be up there with the exotics as was stated above. Heck I've been in it on the NYS T-way @ 145mph!

blonde_man...

I stand corrected... for all that then $20,000 is indeed right on. I should have read closer, at first I thought they wanted $20K for just the turbocharger and some tubing alone. $20K for parts and labor for a full buildup... starting to sound like a good deal, considering what they are going to do. And unlike a Porsche, it will carry four adults AND thier legs.

I gotta disagree with you on the $20,000 not being a lot of money though.


($18,000 for the exhuast? I wonder what the service schedule/ warranty package is like on those cars. One oil filter? That will be $360.15 plus tax please...)

Well it's $1500 in labor to put a trailer hitch on a BMW X5 (they need to remove the exhaust and rear bumper) and that doesn't include the hardware!

Hmm... what u need is a good TT turbo. a GT cruiser like dat should have double spooling since it's heavy. SVX TT....yum.
Can youswap in WRX internals in it together with the EJ20? That should make it lighter. I am assuming this is all amrchair talk yes?

Well this is a great discussion about turbocharging the H6. It would be an AWESOME ride, but to make sure it is a RELIABLE and LONG LASTING ride, I'd emphasize a VERY important thing: the ENGINE COOLING SYSTEM. The SVX 3.3L engine might have an alright cooling system for stock performance, but I doubt it'll be any good if you upgrade the engine's power output drastically.

Before you do ANY modifying, I suggest you get the FEB 2001 issue of SPORT COMPACT CAR MAGAZINE. In fact, buy it, and then SUBSCRIBE to it! You'll love it, and learn A LOT from ALL the arcticles. They're the best, and have REALLY smart writers. In depth and honest articles about upgrading every type of import car.

Anyway, in that issue, starting at page 162 and going ALL THE WAY to page 195 is an AWESOME article about upgrading and improving the 300ZX twin turbo. What's the big deal we have an SVX not a 300ZX? Well basicly the 300ZX and the SVX have a VERY similar layout, and share MANY parts (intakes, transmission, rear LSD differential, etc etc). Styling aside, the 300ZX is basicly a RWD SVX! Any performance/upgrade goal you have for your SVX, can use the 300ZX/TT as a GREAT example for comparison.

Alright so what's so great about the article? EVERYTHING! Their PROJECT 300ZX is going to have over 500hp (3L V6 similar type of engine to SVX) at the wheels! They are covering everything to make it one of the best 300ZX/TT's out there. In previous articles, they cryogenically treated the engine block and crank, and also gave it an epoxy block stiffener treatment to ENSURE reliability. In this article, they talked about how they bored/radiused our and smoothed/polished all the cooling ducts and waterpump routes inside the engine, because that engine has experienced lot's of failures in the rear two cylinders (lack of water flow/cooling). This eliminated all cooling bottlenecks in the engine, essentially making it FREE-FLOWING. They also put different types Swain Coatings all over engine parts. Some coatings were heat resistant, while others were heat emitters. Also other coatings gave parts (like piston rings) a higher wear resistance. All of these same things could and SHOULD be done to your SVX engine if you want to RELIABLY do some MAJOR modifications/upgrades to it. Check out Swain's Coatings and their other products @ http://swaintech.com/

Not only did they talk about improving the reliability of the engine with all that engine work, but they also talked about adding AQUAMIST WATER INJECTION to the intake system. It's just AWESOME. You get so many benefits from it, that everyone should add it to their SVX's, ESPECIALLY if you're turbocharging it. It has all the benefits of running an engine with HIGH-OCTANE RACING GAS, WITHOUT the $5 a gallon cost. It is great at cooling air intake temperature which will give you more power. Also it'll protect your engine from detonation. It steam cleans the inside of your engine, and even makes your car LESS of a polluter! Don't believe me? Then tell me why do all GROUP A WORLD RALLY CHAMPIONSHIP cars use it? Here is the USA distributor (including prices) for it: http://www.f-max.com/ERLH20.htm Also check out the main AQUAMIST site for it for more info: http://www.aquamist.co.uk/ For some info on Subaru application for AQUAMIST then go to this Subaru SUPERCHARGER site: http://www.rimmersuperchargers.com/subaru.html

Think that's all the article had? Had enough? Well they didn't, so they even had even MORE awesome information! They were also talking about 300ZX intercoolers. There are actually two. One in front of each tire. SVX's just happen to have HUGE empty spaces (can fit 2 car batteries in each side) in front of each tire. Coincidence? I THINK NOT! 300ZX intercoolers would probably fit PERFECTLY in those empty spots in our SVX's! They also talked about getting better air flow to the intercoolers to improve power. They had pictures of awesome intercooler vents and louvres which greatly helped airflow to and out of those intercooler spaces. It's COMPLETELY applicable to our SVX's.

Well I don't want to type the ENTIRE article. So go buy the magazine, and READ IT FOR YOURSELF! You'll love it!

Good luck!
Eric

I find your comment about the twin intercoolers quite interesting. Pity that there are not any inlets in the front bumper on the sides of the main 'intake'. It would make mounting foglights and transmisison coolers so much easier.
