Buy a new v7 sti shorty. Best value for money

Buying a brand new 207 Short block from wingers or subaru directly is about 2.7-2.8k but it's perfect bang for buck.

depends what you're after .. you didn't say? value for money, ya brand new 207. if you got a pretty high power figure in mind (guessing not with that turbo, but have no idea what you're planning down the track) then talk to the engine builder.

Thanks guys plans down the track are track/targa duties wanting 250-300kw any advice or a blueprint would help me out. As for engine builder/tuner was tossing between hi-Tec and PBMS. 

Also wanting to do the 6speed conversion worth it? or just rebuild/replace 5speed every time I understand the 6speed isn't as fragile as the 5? Initial cost for conversion is more but reliability and less maintance (rebuilds) would make it the way to go. Btw the car is a 97 gc8.

Guessing you have v5/6 sti heads? If so use them theyre pretty good for your goals. Be advisable to do a forged bottom end but the block mentioned above is still a pretty good option. 

 

Have a talk to Julius @PBMS about options.

@Furze and @Dairusire have been through the 5 speed to 6 speed conversion maybe they can chime in about that part.. i say go for it if you got the funds and thats what your cars for (to 6 speed). nek minit youre getting a full v10 gdb conversion

Haha time will tell

[Dairusire]

In the grand scheme of things, 6 speed conversion is well worth it if the car is going to be used as a targa car. Even more so for general road use.

Also, if it's going to be for track / targa use, go get your cage and safety stuff first, get it homologated.

As for the gearbox talk, yes the 6 speed as significantly stronger than 5 speeds. Doesn't mean they're unbreakable though. Especially when accompanied with track work / racing. It's an easy swap imho, but depends on what you want to do and how far you want to go when swapping that in.

I love my 6 speed conversion, but it probably was 10k i didn't need to spend

Got to Remember he's including a brand new clutch, and custom valved MCA red suspension on top of his entire v10 STi driveline and hub / brake conversion with wheels too since 114.3... So actually 10k is a pretty good price point.
