I'm thinking for this spring to get a new turbo for my MY02 WRX. I don't know how much I like IHI.. but the vf34 seems to be an excellent option? I was thinking about sending it over to deadbolt before hand to get it P&P. Discuss Steve
bigger turbo = <-- VF23 I say go for it. Lots of other options if you don't want an IHI, but it depends on what kind of power you're after...16/18/20g, APS SR30/40/50, PE 1818/1820, etc Presumably you will be getting some larger injectors and a form of management/reflash to go with it, right?
There doing nice package deals on: -STi injectors -vf34 -walbro fuel pump I believe $1230 I still need a UTEC though. 300whp would make me happy. Lag is ok to an extent.. but a 20g/1820/sr40/50 is not gonna fly. What kind of lag do you get with the vf23?
Go with the 16g turbo. going to have some serious midrange and should have good boost (12-18psi) by 3000 rpm or so. Do some checking on the 16g bolt ons. I know some places are around $600 or so, and check on the free wrx injector upgrades. Russ
A 16g really doesn't need 740cc though. I'm also a bit concerned about the flow pattern. There isn't enough "proof" out there yet. Steve
I searched on nasioc and there were like 0 threads about the 16g. How does it compare to the IHIs? I'm thinking about the deadbolt one btw.
I guess for the injectors, I am going to try and drill them out as soon as they post the drill size. That should be pretty easy (atleast for me). I will do some searches on the 16g, but there are a few threads on them. I know some of the stuff I have read is that they are almost the same, but the 16g will from more cfm (more top end) and the turbine is alot more efficient (better spool). I have some utec logs of the 18g, and that things is at 20psi by time it hits 35-3600 rpm, and that is with the larger 8cm^2 turbine wheel. I know the newer 18g's are running the 7cm^2 turbine, and the spool is 2-300 rpm sooner. The 7cm^2 turbine is a 16g (td05h) exhaust turbine. The 16g is also the turbo that came on some of the mid 90's euro sti's. Russ
I'd like a turbo that can get 300whp. I'm not looking for much more because of the cash needed for a new transmission. I emailed a few places about the 16g. The problem I see with deadbolt is no one has posted dyno charts or reviews of the TD05-16g. Steve
Well, 300whp isn't some sort of magical number below which you're safe. I'm sure I could bust my transmission tomorrow if money was no object and I didn't care, and I'm some way short of that amount of power.
I know it could be easily broken at even the stock HP level based on abuse. But 300whp seems to be safer than 350+whp.
Once you hit the 300whp+ area, you will have to worry about more than your tranny. Most people who run at or above that level are also getting new motors. Given, some of it may have to do with tuning, but there are alot of motors that had good tunes that let loose. Russ
