Default Thoughts on Precision turbo chargers

Just wanted to get some feedback if any of you guys have tried their turbos
I think they are a US company
They have billet turbos too
I was thinking model 6262 or 5862, both which are billet wheels
Obviously this is going on a rotated setup and running ET 2.1 block

Wiley

I would have look on Borg and Warner EFR range,they're looking like great choice

And about the Precision 6262 they're very popular on Honda and other cars,probably worth have look on the Nasioc,there is few threads about them

Borg Warner EFR won't fit straight on the RCM rotated kit unfortunately, shame because it's an awesome turbo in twin scroll configuration.
With no AVCS on your car Wiley, I'd be tempted to fit a Billet 30R with a .63 housing on it. When you port the heads and fit decent cams later to improve it even more, it'll work very well indeed.

Example of a similar set up.



Meth map above, it made 530bhp on Vpower.

I've not heard of any Subarus running Precision turbos over here, so can't comment on what they'd be like.

Is there a twinscroll rotated setup available then Martyn? Or is it only single scroll conversions that are available?

There is for the American market, or you'd have to get one custom made over here.
From my brief experience of them on Evos, I'd say it'd be a very nice set up on an AVCS equipped 2.1 or 2.35.

This is a 2.3 Evo fitted with the EFR7670 which would be my choice for those wanting really good spool and mid 500bhp topend.
No MIVEC on this one either, so one with that would spool even faster.

It's just a pipe dream at the moment tbh, I will upgrade again from the lm450 I'm currently on, but that will be when I have sorted a sound 2.1 conversion, I like the feel to my car with the twinscroll tbh, and after having a uk model, granted it was only on the vf35 but the difference is quite noticeable to be fair, I'm hitting the same kind of boost at the same rev range on my lm450 as what my 35 would achieve so it makes for a good lively road car, but I know what I'm like it will only be a matter of time before I come knocking for a motor if I was to undertake that project now I think my mrs would sack me because of the number of cars I have sat on the drive lol, think ill have to shift my m3 and start to play about a little

Just waitin to see what Tyrones car will be like, sounds like it should be a good toy

Martyn agreed they will not fit straight on,but with modification should be no problem to fit,but I'm sure is out too Single Scroll T3 version,but as you suggest 30R should be good and maybe better option

Must admit looks like on EVO working this turbo well

Martyn is this on V-Power or V-Power and methanol?

Great results

Straight Vpower on the Evo, as it's a Hillclimb car funny fuel isn't allowed.
