different stroke for different folks I guess. It's your car and whatever makes you happy.

It's just that I had a vf30 before. Big difference. I got tired of the vf30 real quick. The up side to the vf30 is that it's smoother. My 18g hits like a hammer at about 3500 rpm. Kinda of like an on/off switch. I made 273 whp on the vf30 @19 psi.

Sadly, everyone is getting faster in my town now, I'm eyeing the gt-30's, superzillas, and greens now just so I can keep up.

34s have made over 300whp on the 2.0Ls, my friends in fact landed 322whp...and 354 whp is a damn nice number, but what was the rest of the setup, IE block, internals, IC, intake, exhaust, oh and cant forget the big one, tuning. How long is that 18G gonna put out that much whp daily? All i was saying is that the VF series turbos are good choices for a decent increase over stock, and are very well suited for daily driving. And yes, thats another point, you can find very good VF turbos for pretty cheap now a days...like you said, VF39 for $300...i would do that in a heart beat if i didnt have a Ver. 7 STi engine. Also, I had asked a tuner about going with an 18G because thats originally what I wanted and he told me not to, which is why I said that the 18G wasnt worth the extra money over a 34...but then I guess that all goes back to what it is you want out of your car.

The Green you are thinking of is an awsome turbo....very low boost happy turbo...hehe. I myself might go that route.

What does a vf34 make? like 250whp?

I think a vf34 flows like 400cfm vs the 18g's 600cfm on a 2 liter.

Why am I arguing this anyways? The GT-30R is where it's at. I hope to buy one sometime.

'I guess if you can pick up a vf39 for $300 or so, it would be a good deal. Which is a decent improvement over stock.
disco potatoe is better

The disco potato is a good turbo. I want a straight line set up though. I'm going for top-end

Probably not long. lol... I'm probably gonna go with the same v7 route that you're doing.

If it came down to a $700 vf34 and a $850 18g. I'd go with an 18g. Maybe some people have put down 300+whp on a vf34, but that doesnt happen often. I'd say 5% of vf34's do that. While 95% of 18g's hit 300+ whp without breaking a sweat. The limits of the 18g might be pushing the limits of the stock ej205 though.

Yeah, that was what I was trying to get at...but on say a Ver. 7 like I have and like you might be going with....the 18G can really stretch its legs and get some air moving, not to mention have 1000 more RPM to go than the US WRX motor. Most people on here are running the stock EJ205s in their WRXs, some have built them with new internals, but not too many.

And I more than likely would have done the same thing you did for those prices.

I use my car as mainly a daily driver making engine health an issue. I would much rather run somthing that gives me a little more mid range top end flexability like the 34 than having all out power that may risk ..... well blowing out a ring and forcing a premature rebiuld.


besides its cheap enough that when i do deside to biuld the enigine out i can easily replace it with something at the time that will get me much bigger numbers but safer and im sure i wouldnt have a problem capturing some money back on the resale of a used good condition 34 to help me into a 30r or green.

I got my front clip from www.finelineimports.net Talk to them, Miles and Ryan are good guys. Tell Miles that Patrick sent you. They can get you pretty much whatever you want...STi Ver. 2 all the way to brand new Ver. 8's, which they actually have right now. Depending on what you are getting...look to spend about $8,500-$10,000 for a JDM conversion....if you are throwing it into a WRX, thats a bit easier as the engine going in is damn near the same as the engine comming out....you would need to add the 9 wires for the AVCS, if you choose to run it, and then swap the US ECU for the JDM ECU.

okay first of all, sure 18g turbo is nice .. buh for 150 more? i dont think so. you have to get larger injectors to maximize the potential of the turbo, and looking towards block and drivetrain. Oh, your maxing out your block already when you have stock internals and stock 2.0 L, around 350 whp is the max, and a lot of stress is put on the block which = unreliable, and potential break down = very high. same goes for the stock 5MT. so lez see vf34 + 560 sti injectors + walbro fuel pump + ecuteck tuning = roughly 1800 at gruppe-s.com and now build motor = **** load of $$$$, tranny = **** load of $$$$ and sure theres that 150 dollars more.
