Best single turbo kit?

BlitzBoy : where does the T04Z fit into the HKS range and what is "HPIAB" all about? (HKS don\'t have it on their comparison chart http://www.hksusa.com/categories/more.asp?id=1094)

Hi Chris

The T04Z is essentially a ball bearing TO4R. I read ages ago it was going to be a T04R exhasut on a T51 compressor with a BB core. Looks about right.

Hi All,

Here\'s my personal views on singles ( bound to upset someone!!)

Yes with the GT42R I have on the car now with big ports and have loads of Lag but when l ran my car with an extended port engine ( exhaust only), 35/40, 1600\'s and stock primary\'s we found that at 0.9 Bar we had 400 horse easily .

It not only ran a 12.2 with absolute rubbish gearing it was and still is far and away the nicest FD to date l have ever driven, with NO lag because l had full boost the second l went near the throttle, giving the car a  totally predictable progressive linier power delivery.

This meant it was now an FD with no vices be you in the dry or the wet, leaving you with out the twin turbo is it going to spool up and catch you out feeling.



For any of you buying the Horsepower in a box Turbo kits, a word of warning.

There are several people on here with bad experiences of this company\'s kit, ( hopefully they will come out and say)  

Yes the Garret Turbo is the same as the other various Kits on the market  but the important bit is the manifold and unless  Horsepower in a box have got their act together their manifolds are, putting it nicely "suspect on reliability".
This is because people have had flanges warp and primary pipes crack resulting in at least two people that l know of having to have new manifolds fabricated over here after giving up with the reliability of the Aussie unit.

Yes they are cheap but as they say "you get what you pay for"

Spoken to Morrie about the Manifolds, and assures me the manifolds have been improved, I might have extra welding done to it when it gets delivered in any case.
Yes 20B_Boy is correct in the spec of turbo, BB version of the T04R with the different compressor.
Even if the manifold goes t*ts up I can get a one fabricated for less then £300, Im still saving over 1.5K!
The most important thing for me is turbo is a full blown Garrett unit NOT a cheap copy. HKS do a version of this called the TO4Z signature but this was mucho money.

Ta for the info, the T04Z looks to be in the right territory for me (>400 rwhp)

I\'ve been on a sloe journey towards that kind of power - going from a standard car to ecu, de-cat, induction and porting (plus breaks and suspension).  I\'ve now got all the bits in place to go to the next stage (1600 inj, fuel pump and reg, boost controller, down-pipe) once they\'re in place I\'ll look at losing the twins next year for a single.

There\'s basically no need to do it all at once and you can pick and choose the right bits for your requirements.

Before the single goes on (and after the next step) I\'ll have to do the clutch, engine and diff braceing.  If I were to have done it all at once

a) I would have ended up somewhere but not understod how the changes alter the way the car drives
b) Had to find a large pot of money - probably 10k all in.

The pleasure of modding a car is, for me, in the gradual process.

The ultimate jouney I\'ve seen anyone doing with this is Glenn and his 4-rotor project.  Been going years and still has a few to run I guess but it\'ll be perfect when done!

[chrisBoid]

Good point about the gradual change and being able to see how the handling is altered.  It\'s the cost of labour when doing it bit by bit which concerns me (including multiple mapping sessions)!

Interesting that a few people on here recomend fitting a diff brace as part of a big single setup,is this something to do with the extra torque having adverse effects on the drivetrain.....?

Whoohoo, my kit is being sent by fedex on monday!!!! cant wait.

Yep I will be fitting a Diff brace as well as an engine torque damper brace should help with the gear changes.

[Warthog]

Well Blitzzzzzzzzzi baby. My move to single will be later this year, it will have to be a winter project as need to free up some cash from a property we are selling.
I have made my mind up I want a 10 sec street rex and will be going Skyline hunting on the strip. :eek
It is going to be a new engine with the same porting etc as the 9 sec car, T051 bb, uprated gearbox, diff etc so will cost a pile of beer tokens, which will be donated to the RE:WORX crew.
I am still intent on holding the twins british record before i go single and will resume that task as soon as we have the parts to sort out my side seal problem, ( which i have traced back to a turbo spike whilst overtaking prior to Geff fitting the PFC and tuning her, my fault too much right foot. ).
Watching your project with interest. Catch up with you soon. Best Regards. :wave

Oh---also fit the gearbox brace, it does work and makes for good changes. You may want to let the gearstick spring out of 2nd on the change up and then just push it in. I found it stopped any chance of missing a gear or hitting 5th. Try it see how you get on. :wiggle

[BlitzBoy]

Warthog, you going with the T51 then, cool, SPL version? that thing sucks up small children I heard lol :eek

[Warthog]

Yeah, it\'s going to be funnnnnnnnnnnnnnnnn. :3gears-rh

[interloper393]

Im jealous (

lol

not trying to make u jealous but here are some pics of my kit which i recieved yesterday
