This guy sells nice turbos at good prices

You can get manifold and wastegate etc seperately.

The T04S or GT35R are good for 400 + easily

Question has been asked many times, use search function buddy

Depends on what spooling you want too ?

TO4R and T78 are awesome turbo units, on the US forum the T78 got voted best unit for a FD, i had it on the Purple rx and deffo awesome power when they come in @ 4500rpm or so.

Now have the Apexi RX6 unit which spools at 2800rpm but will max out at about 480bhp @ fly :Laugh

the gt35r spools early and unless u are going to spend real big bucks the bigger turbos just arent needed
the average rex uses between 1.1.4bar max on a single and this turbo can easily handle this boost

To add to Paul\'s comments, the T series are old technology (originally designed for trucks I have been told) and will take up more room in your engine bay, and are much less efficient than the GT series of turbos.

To4\'s are a cheap and effective way of making more power. People have had good results with these - To4e or To4s are great for the street with the R/Z variants used for higher top end.

Alot depends on your budget,the To4 series of turbo\'s are indeed old technology(some 50 years),they do work,but are inferior to the GT series of Garret turbo\'s which have much more efficient compressors.
A GT 35/40 is a very good turbo for quick spool(1 bar at 3000rpm with right A/R\'s) and flow at top revs too.

You looking for more power already bud? Sheesh, some people are never happy! LOL. I\'ve done a bit of research on turbos and always liked the look of the RX6, as said above, great for low down power and circa 480bhp maxed out. There\'s not much on the roads that you\'ll not flame easily running that type of blower.
I\'m still considering if to go for a single or the V8 conversion (dont flame me!!). I like to rotary but for sound and oomph the V8 does seem a bargain. 400bhp and 400 ftp torque and a deep V8 rumble Vs Rx6 turbo?? I cant decide!

nah mate not right right now! just wanting info for in the long run so i know what am doing plus i could not used a 450+bhp car for a daily driver with the petrol prices now lol! need a difo car first!
Title: turbo upgrade?
Post by: Bobbit on December 18, 2007, 01:39:42 PM
I agree with the petrol prices, again thats were the V8 seems more appealling too, slightly better economy with aparently near 30mpg! A down side tho is having to buy twice as many spark plugs! LOL

Post by: Bobbit on December 20, 2007, 10:40:41 AM
the v-mount seems to get the best reviews.
