Default more power

currently running stock 2wd engine greens 500 cooler & t34.48. Im going to be looking for a bit more power for the summer so going to start collecting bits.

thing is im not sure what route to take, firstly what can the 205 block handle safley ?

firstly i was thinking just going for a .63 housing and a new chip, chris at torques said id see a good 350-60 with this.

im also thinking greys and the above ?

but also the siemens route, i dont want to go for too much as its a low milage yb and dont want to ruin it just yet.

what are your thoughts...

i say .55 light blues/gerys or the seimens and push it up too the 360-380 mark should be a very quick road car

Was on phone about a .63 housing yesterday not cheap things come in just under £400 quid. If ya did this i would say as what people have said a good 360-380 bhp block shud handle this no bother< and a decent chip. maybe try siemens 55lbs injectors or greys. or get head polished and ported and maybe throttle housing to match it

my spec was similar spec to Doug "mechanic28"

i had a t34 with a .55 exhaust housing; siemens blacks 55lb, 500 cooler, msd chip, and a bog standard 205 blocked motor (in good condition to begin with)

i can honestly say it was an awesome road car; i never had it on the rollers but i reckon it was 360-370hp - peak 2 bar of boost and hold 1.7

very very quick road car

205 block is fine for 450hp in my opinion, seen as much as 500 through em providing its in good condition to begine with

best thing to do is decide what power you'd like or posibly go out in a few different spec'd cars then decide

.55 are not as common as .63's try and buy a turbo off someone you know or know the turbo to be in good condition

find out the cost of a new one before looking around for a 2nd hand one; you'll get £100 for your t3

My last cossie had a t34.48 on 803s with a custom mapped chip by Karl Norris and it was awesome, so spritely and responsive peaking at 1.9bar holding 1.7bar. It could've made more power with the .63 and greys but the driveability and response would've suffered.

WHY are you looking at a new turbo/bits ?
A T34.48, if it is a proper T34 with .6 AR compressor housing will piss 380 all day long, no porting, no nothing, just add chip/map to suit the greys, and you're there.
CR Turbo's man had a 2wd sapphy on a T34.48 doing 380 all day long, a massively quick responsive road car with next to nothing in lag terms.

The .60 AR comp housing is the normal size on T34's, but as there is a lot of swappsies done could be different, the .60 is just std on large turbo escos, will lag a few more hundred rpm compared with a .42 ar, but far bigger hit when it does come in.

in all honesty i think i ruined my car with the power..................most fun i ever had was .48 housing and a decent setup (i had BD 10's as well which I still have if you want ) and it was the best package on the road.

there is alot to be said for driveability!

Mines on a .48 housing wiv cut back blades and a 360 roller bearing but has had the boost spike mapped out to be gentle on the gear box, so car is really drivable just no throwing you back in the seat lol if im honest car seems slow until you look at speedo and notice how fast your going,it so smooth

it was a good 350 plus i used it on track for 1 session at rockingham and only 1 session and on rockingham it was as quick as a escos witha T38 and greys as it was a lot more responsive out the corners he could only catch up down the straight

Glad people are getting the driveability bug just so much nicer in everyday use, and unless balls out faster too, as you don't have to book aceleration in advance like you do with a T4 etc.

the .48 will run out out air wayyyyyyyyyyy before the greys run out of fuel so no point and you will just be losing resolution over the greens for no more power
