Hey guys, I've been looking on prospeedracing.com for the best turbo to upgrade.
I'll be trying to achieve 220-250kw at the wheels on a MY07 TBSTi. Supporting mods are a PW TMIC, DW65C, ID1000's, Invidia 3" TBE and a Grimmspeed 3PBS.

I've been told a VF52 is a pretty good option, but I've seen a Tomioka Racing TD05-18g/TD05-20g and a Blouch RBK GT380 XT/GT440 XT for sale on that website for around the same price range.

Any differences between them? Which is the better option? Kinda confusing and spoilt for choice haha, want to make the best choice possible and not regret it.

Cheers guys!

A vf52 is a bit small to reach that power goal without going e85. The 440xt will get you into the upper range of your power goal on 98.

Do you have an auto or manual tyranny?

you could also go a 1.5XT-R, depending on your intercooler setup - if you're running a PW cooler, you can just use the alternative hose. It would get you the power you want with better spool.

I've got a manual gearbox. Yeah I will most probably be running 98, but if I choose to run E85, I'd make alot more than 250kw and go into rebuild/forge territory (with the 440xt)?

Yeah I was looking at the 1.5XT-R, its a bit outta my price range at the moment. But it is a good turbo I hear. Slightly quicker spool, little bit less top end.

I'd go 1.5xtr 8cm but only on e85...but if to expensive, I go blouch 440xt 8cm

1.5xtr - 260-70kw 98ron
440xt - 240-50kw 98ron
Tomioka 18g - 220kw 98ron
Vf52 - 205-215kw 98ron

Someone correct if I'm wrong

Add 12% with e85

We sell headers to suit - viewtopic.php?f=68&t=25478

Great post Jack, thank for posting that. I always wondered what would be best also. Do you have an idea when/what range these turbo's kick in best. i.e. Brand X turbo kicks in at xxxxrpm and is produces it best power in its low/mid/top end range. Brand Y turbo kicks in a XXXXrpm and produces it's best power in its low/mid/top end range.

Also depends on headers n intake used.....

And headstuds and ringlands.

These are suppose to be good check em out.

Id do whatever ryan (blacktop) did as he hit your upper target on 98 without it being laggy. What turbo did you get Ryan? I forgot. From memory he has headers and an intake though.

Just remembered there's a 1.5xtr for sale on here with only 1000-1500kms use.

Honestly with 250+ kw on an ej255, it is not a matter of if, but when.

booo party pooper! He did say 220-250, so if he goes the lower quartile of that dream it will survive

If your also tight on cash kingugawa make budget turbos like the td05-20g and they are definitely not as bad as people seem to think.

Otherwise other options may include a garret variant eg. gt(x)3071 or 3076 if budget permits.
Borgwarner EFR range seems to also be capable of working some magic

I would have thought the lag in those kinugawa turbo's would be a turn off. Especially in auto.
