Is it possible?

Could i get bd14 cams and sweedish plenum, 10mm spacer plate and a few more small bits and pieces to get 400bhp from a t34.63?

cheers

 

yes it is possible as i have 418BHP but that is the turbo at its max and i would of thought if used hard wouldnt last very long.

Pete

 

what is your spec mate?

cheers

 

ive got a t34.48 on mine. And after nms mapped it, he said it would be about 400bhp. Stage 3 spec with headwork,32psi spike and holds 28. But no one else seems to get this on .48? Not had it rr though.

 

I think 400bhp on .48 will be very hard, maybe about 360-370.

 

well only going by what karl told me. Whatever it is i want it faster lol.

 

No need for bd14 cams and sweedish plenum, 10mm spacer plate

ported head ,greys ,rs500 intercooler will see 400bhp from a t34.63

 

the T34 will be at its limit to see a true 400hp!standard set up can see 400 but again on the limit of the engine flow rate with the head/cams etc

 

got just over 400 on mine with t34.63 ported head, low comp and greys with standard cams

 

T34.48 is ace around 380-390, with seriously reduced lag compared with .63, so everyday driving will be quicker.

sierra 2wd, std bottom. I get 406bhp and 520Nm with t34.48. polished head, big cooler(not rs500), 80mm custom exhaust, light aluminium propshaft, siemens'55, MSD chip. 2.3 bar peak, 2.0 bar at 6000revs and peak of power. after 6000 power and boost reduced.

 

I had 406bhp and 410lb/ft on a harvey gibbs engine running a t34 with a 0.63 housing. Was running motorsport blues (400s) rs500, ported and polshed head, etc.

Turbo only lasted every 12-18months

 

how is 380-390 bhp made on a 4.8 i thought it was a bit of a struggle on a .63... What are the Driving differences of a .48 and a .63?

What rpm do you spike to 2.3 bar? and what actuator are you using? personally i like revs and would hate my power/boost to drop off after 6,000rpm

Where could i get my head ported and polished?

cheers all

 

speak to karl norris about getting your head done, not the cheapest but you get what you pay for

 

The smaller the turbine housing the less lag it will have, all else being equal, the larger housings lose more off boost ability due to more lag, so when the power comes in there is more of a marked kick, as there is a larger power gap to make up, as it did not produce the goods to start with.
Fine on a 4wd but it's going to break traction so much easier on a 2wd, even the .48 in the wet is terrible if heavy footed.
As the end power(asked for) is basically the same, I don't see the point is losing the off boost ability.
There is a monstrous difference between .48 and .63 off boost, and so in everyday driving a .48 will be much livelier without trying and needing to drive it in the power band, like a type r, shit torque needs zillions of revs, shame as they're awsome cars.
Up to you what you prefer, the .63 will feel faster owing to a bigger kick, but by the time this happens(around 35 minutes later!!) the .48 car will be home for tea!!
I just think with the limited traction of 2wd versus 4wd less kick is better, you can concentrate on driving not watching the tacho and holding off for fear of a boost kick spinning into the nearest hedge, 380-390 very reliably on a .48, seems better than a 10bhp gain(asked for) with all the disadvantages, of a .63.

i was told a .48 will max out at 350

 

I must admit my saphire that was running 310BHP and run around town nicer than my 3dr with a T34 .63.

i would say the smaller housing makes for a better alround drive.

Love it when theres nothing and you just get a bang, must come in hard then, i remember a stock t3 cossie with 270 being Quite harsh.

At what rpm should a .63 hit full 2.3 bar spike? 4-4500?

my starlet was 4,000 on td04, and was going to be 5000-5500 on the td05 16g. i do love a bit of lag

Have to remember though, the car wont be on boost every day , im having a msd live map so hopefully return good mpg off boost too.

 

T34 .63, will pick up properly about 4300.
T34.48 will do well over 350, the man from CR Turbo's used to use a T34.48 on his 2wd sapphy around 380-390.

4300, thats grand! i can live with that cheers tab

 

we just done a fantastic t34 . 48 engine, pulls 32psi at 3k and 395 bhp and 400lbft god it goes

t34.63 best we done was 430bhp on a proper specced engine

 

what fair shout what is the full spec of that and did it come in hardish atall

 

top one, dosnt come in too hard just pulls from 3 to 7000 soo well, properly nice road car,

bottom one i dont know was just one we did on the dyno never got to go in the car i guess it would come in pretty strong,

spec wise, its something a bit different lol

 

fair shout then i dont know wether to go for the 48 or 63 now i want something fast and hard if you know what i mean lol

 

48

 

but how do i get over 350 on a .48

 

my .63 is on song well below 4000rpm

 

i got 403bhp with greys,bd10s 500 cooler etc and a t34 .63 standard bottom end and standard head

 

easily, as above just done 395 on a 48, dont think your gonna struggle
dont need to touch the head, inlet cam, injectors, chip, and tbh, your pretty much there, put a group a head gasket on there whilst your at it, dependand on whos chip you may need the compression changing a little

but i say this loads, if your gonna do it, dont ask on forums, go to the tuner you want to use and do exactly what they reccomend and use their chip other wise its not gonna work, unless you have a live map ofcourse !

 

Don't bother with a group a head gasket mines just destroyed one, pay the extra and get a 4 layer mountune 1 instead, thats the advice I've been given from the boys in the know and have just ordered one.

 

only reason i say that is barry asked about 350, for pushing 400 or there abouts i agree

 

yea i think cams will help...Anyway im settling on a .63, i hate turbos which are instant and dont give you a lovely feeling of nothing then....BANG

Also... i thought diamond cut lattices on a orange lense'd low saph would look mint... until i saw yours on those mo's...

i was talking to jb fletch last night, and he said to get a ybo611 is it? these good i take it? or should i get a WRC

 

0611 is what they call a group a, go for the wrc one if your heading for the 400 odd mark

 

seriously pay the extra for a 4 layer not a 3 layer if your going for a fully blown t34 it will be better in the long run, mine was a 3 layer wrc one that has blown and mine is long studded aswell. I have just paid Ł150 for the mountune 4 layer job these are widely used on 600bhp plus engines.

 

Sound fella's... Am on it like paint on a car bonnet.. Wrc 4 layer it tis

Right, am gonna be a bit of a thick twat now.. my heads been fucked about all day with breakin my car for spares an all... What cams would be best for my setup...

Bd10 inlet and bd14 exhaust? are they simples to change? dont i need to take them out to remove the headanyway?

Whats the difference.. bd16 open valves longer?

Im scared about hitting a valve on my piston!... im used to non interference heads! lol...

how hard are the yb to time up?

much love for answering these questions btw

 

are you having a live map or a chip or shelf ?

 

live map by stu at msd?Thats what i was going to get, or should i get one of his chips for greys etc?

 

peice of piss to time up!you want to able to fit bd16 on standard c/r cossies bd 14 are a no or very tight(can not remember) on non pocketed piston you would deffo need verniers !

standard cams are good for 400bhp mate!

 

aye, fuck cams lmfao, My arse would be twitching like fuck on the first turn of the key! haha

Stock it shall be... With maybe a 4x4 inlet and spacer?

 

My Cossie made 394 bhp on a T34.64 holding 32psi on standard head, standard cams on siemens blacks, a 70mm core RS500 cooler and 4x4 inlet.
