as title; what would i need to achive this on my 2wd saph?
and can it be achived by just a chip, injectors and turbo swap?
atm my engine has 4x4 pistons and a group a head gasket, dark greens and T34.48, other than that is pritty much standard not long rebuilt....

 

Rob, dont start chasing numbers mate!

personally 400hp is a weird number to go for, your caught between a t34 and a t38.

you can get your's to a nice 340-350hp with the injectors and turbo you have so the cost to go for 30/50 more hp isnt really worth it in my opinion

if you were to do it however you'd need a t34.63/ t38 , a set of Siemens/ Greys and a new chip to suit.

assuming you buy used parts

£120 -£150 injectors.
£250 - £325 for a decent chip
£300 - £400 for a turbo.

personally i'd stick with what you have, it will make for a quick road car, you're only running 18 psi at the mo, you can easily run 28psi through it and still keep the same injectors and chip.

what chip do you run?

Matt

 

you will need a rs500 intercooler and a 044 fuel pump as well as above

 

go for greys & the t34.48 28psi plenty enough for a road car

 

Siemans injectors, T35.55, 023,swirlpot & 044 pump, 500 cooler, breather system, NMS live map is hopefully seeing me to 370/370

 

A decently set up T34.48 will piss 380 all day long, the last set of dark greens I tried were at 80% duty at 300bhp, and they had just been cleaned literally taken straight from cleaner to engine and ran 30 minutes.
I use greys and a 044 pump, but a healthy std pump is very able to supply enough pressure for 400 and more, the important word being healthy with a nice current supply(ie REWIRE).
You cannot use your chip you have at the mo, it will need either another chip to suit or a remap with such a difference.
A 500 cooler is a must, as is a decent breather system.
A decently set up car with a solid 380bhp and on a T34.48 will be very rapid with little lag, not like waiting for a bus like T4's etc!!
A certain man at CR Turbo's had the above spec on his 2wd sapphy, I've seen more out of this spec turbo though if wanted, I assume you have the usual 360 bearing, step gap seal ?
You may need to look at the ignition side if there are problems with more boost though.

cheers for the replys guys, i forgot to add i do have an rs500 size cooler + baileys breather system.... just wandering really what it would invole but i will probally be keeping with what i have atm and get it propperly set up to get 100% out of what i have first....

if i do go for max on the setup ive got (t34 + greens) will i need an 044 pump? im running a std pump atm and it has been re-wired (i.e running alternator voltage at the pump)

matt - its an msd chip...

tabetha - im 99% positive it has the stagger gap seal and the 360 thrust bearing as i know the guy that supplied it and he said wouldnt have ordered anything less

 

your standard pump is fine Rob, if you want a hand upping the boost, then give me a shout

 

my standard fuel pump maxed out at 355bhp

 

cheers mate will no doubt let you know what happens!

 

The main difference between the std 941 and the 044 is the lockout pressure, that being much higher on a 044 at 11.2 BAR/18L minute and18Amps at 13.5 volts.
The flow rate is not that much different between the two.

Mines somewhere in that area, Harvey gibbs T38, 403's, 044 rewired for 13-14v, 70mm intercooler, bailey breather system, L8, MSD chip, MSD coil pack, 500 airbox & K&N, double piston dump valve and 30psi

 

Tab,

I think a T34.48 will be gasping for breath @ 380bhp tbh, a .63 housing would be more comfortable imo.

Rob,

Like most of the guys have said, a WELL SET-UP T34.48 car makes a hoot of a road car, i had this set-up for a year on a NMS Live map, Greys etc peaking @ 32 psi, holding 28 and there wasn,t alot that could live with it tbh cus the turbo is on the money from very good revs and pulls like a train to 7k or so.

I,d try this and see how you get on, imo i think you,ll love it....

 

cheers guys, tbh i dont really want to loose the turbo as it is so drivable, its not running its full potential atm so il get it set up / dyno'd etc and see where i am with it

 

Let me have it for a bit Rob i will sort it for ya

give me a couple of week tho lol

Paul

 

i go to turkey next week for 2 & 1/2 weeks

 

have you drove a car with a t4?, there not as bad as people say, i prefer it over my t34

 

The 2 i done Rob made 347 bhp and 344 bhp you could go for siemens 55Ib and another chip but tbh i'd go for a bigger turbo if wanting anymore

347bhp was on a T34/48
344bhp was on a T34/63 this one made a little more torque

Paul

 

ive got a .63 housing on my saff,500 cooler, msd chip,55lb blacks and ggr breather and it pulls like a train and in the14 months ive had it it hasnt missed a beat
cheers james

 

I've driven a few T4 cars, they are worse than I thought, bit like a type R, nothing, nothing, "shit, hold on tight", fun but in everyday driving I'd have a T34 anyday.
tabetha

 

what pressure will accept a T34 .48 ??? with the configuration ?
thanks

 

Thats why i love it lol....

p.s
my car is lucky if it does 2k a year

 

ive never been in - or driven a cossie with a T4 but ive been told the gt30/35 turbo (due to it being roller bearing) would be the way to go?... like ive said tho think ill be hanging on with what ive got mabye change to greys

 

paul; what sort of boost were they running at?

 

Greys are old hat mate i'd go for 55lb blacks which can see you upto approx 420 bhp if you wanna change later

As for the other 2 saff was peaking around 28 psi and holding 23 psi for 347
and the escos was again 28/29 holding 21psi (bigger turbo= less boost similar power)

Paul

 

GT3071 is the way forward

 

im on t34 .48,light blues,bd10 inlet,scs chip,500 i.c it made 388hp and 375lbft on scs"s dyno so all PROPER figures!pulls like a train no lag,and pulls to the limiter a treat.
