Found the ultimate bolt on turbo upgrade for the Suby powered 914. Keep in mind no turbo system is ever just bolt on. (IMG:style_emoticons/default/blink.gif) (IMG:style_emoticons/default/headbang.gif)

After you install a downpipe and exhaust Upgrade to a Walbro fuel pump Upgrade to 750cc injectors Convert your intercooler to a different location Modify all the hoses, lines, and brackets surrounding the turbo Buy an engine management system and have it pro-tuned Oh yea... and fork over over $4000---LOL Those Greddys are no joke though |

Yep, it cost money to play with turbos. But still 750 HP. (IMG:style_emoticons/default/happy11.gif) (IMG:style_emoticons/default/idea.gif)

It says the turbo is good for 750 HP, doesn't say the engine is good for that much. That turbo is waaaaay too big for a 2.0 or 2.5 suby 4 banger. (but that won't prevent kids from trying it)

Do you really need that much more power in a 1 ton car? Plus, if you were going to upgrade, you would go with a much cheaper turbo (IHI VF-34 or a few others) that doesn't necessitate a fuel upgrade and work with the same flanges.
I shudder to think what a USDM STi engine with a turbo upgrade would do in a 914. |

I have seen, driven in, a few rally WRX's with crazy turbo upgrades. Let me tell you these things pull like snot and with the big ass turbo. No you don’t need that much more power in a 1 ton car. But believe me its fun. Yes I am sick. (IMG:style_emoticons/default/cool.gif)

I shudder to think what a USDM STi engine with a turbo upgrade would do in a 914. No doubt... I've already upgraded to a 4-inch downpipe, a 3-inch catless exhaust, and a Cobb Accessport with a stage 2 tune (285 HP) My next upgrade is an effective, yet cost efficient STI intercooler, and a VF-39 Turbo. Total cost will be under $1000, and put me at 330 HP. More than enough for a daily driver. Of course.... thats in my WRX. In a 914? That would be just STUPID-twisted fast.

I am running stock 2.0 with stock turbo and intercooler in my 914. I am taking it to the speedway next weekend to have it professionally tuned. The only mods I have are custom up and down pipes intake and custom exhaust system. He is going to reflash my computer and should see gains at the rear wheels of somewhere between 24-30 hp. So I should be very close or slightly above the 300 hp mark.

A GT40r in a 2.0L WRX will be extremely laggy...take a look at this dyno of a smaller GT35r it on a larger 2.5L STI motor:
http://www.clubwrx.net/forums/showthread.p...ght=sti+pistons Imagine the lag and narrow powerband a GT40r would put down on a 2.0L engine...but it would be fun as hell. I'm choosing to run a 35r on my 2.7T project....but it was a tough decision to not go with the GT40r. |

Do not know the actual weight of the 2.0, but a friend and I can easily lift the complete engine. And no, I am not a musclehead. 6' and about 175lbs...

And when the 2.0 Suby motor gets to around 450hp the head studs stretch and have to be replaced with larger diameter ones. Then 600hp is possible, but its a bit of grenade.

the suby -4 engine is about the same (maybe 20-40lbs lighter) as a type 4 engine. (IMG:style_emoticons/default/burnout.gif)

330HP with only a $1,000 upgrade?
What does that motor weigh? If it's light, it just might be the perfect motor for a serious 914 hillclimb car. [/quote] Well, not exactly....... my 06 WRX is rated at 230 HP, but in actuality, it performed around the 240HP (12 lbs of boost) range on the COBB tuning dyno. I've already spent about $1100....... $650 for a COBB Accessport reflash tuner (currently running a stage 2 program), and $450 for a full turboback exhaust. Currently running 15 lbs of boost. For ANOTHER $1000, I can purchase a VF-39 Turbo (Standard on WRX STIs), and an STI intercooler. On average, they go for "about" $450 and $320 respectively..... many times on units with less than 5000 miles. (Those STI guys buy their cars and tear em apart to upgrade almost immediately... so the parts are cheap) I can reflash my accessport (free to download) to run a 93 Octane, stage 3 program with the 2 above mentioned upgrades, and I'm at 330HP. Now..... this is only on an 06 WRX. The 06s came with 2.5 Liter engines, all earlier WRXs came with 2.0s, and to do the same upgrades, would require a bigger fuel pump and injector. Mine doesn't. My fuel system can support a VF-39 without modification. That'll put me at 17.5 lbs of boost. I'll be there by the end of the year. (IMG:style_emoticons/default/smile.gif) |

Good luck getting a pleasant 400 hp out of the 2.0. Lag will be crazy, and when the turbo kicks in you will just spin your tires. And then, everything will break. The internals can't really handle that for very long (USDM). The 2.5 is the motor to use. $3000 gets you 300hp and 300 ft/lbs STOCK.
Even the race guys don't recommend too much above 450hp on a stock internal 2.5. |

Anything more than that... then I'd have to start getting into clutch upgrades, fuel system upgrades, lower reliability, lower driveability, lower fuel efficiency, etc. Once I get to a stage 3...... then maybe I'll tinker with the suspension a little... but I'm done as far as engine upgrades are concerned. After all, this is my daily driver... Hell, I drive my kid to school in it every day (IMG:style_emoticons/default/smile.gif) |

The guys at Outback Motors build up really powerful Subaru motors for sand rails. Their web site has some interesting stuff on it, and as you exceed 300-400 HP, prices start going up really high as jsut about everything internal gets replaced. Even the block.
http://www.outbackmotors.com/400hp_setup.htm 400 HP - $13,000 500 HP - $16,000 They also make a 600 HP engine but don't list the price. -Tony |
