as title guys as there is ollies old nms stage3 t34 .48 turbo for sale and as i want like 280hp i might aswell get it before finishing my car and save mapping it twice..... and sell my stage 3 t3 .... and gotech

plus i want that p8 cosworth management thats for sale too.

but what will the turbo be for and its only a weekend toy for playing around in.... and what power could this turbo go to.

T34 with .48 and cosworth management is awesome. Many of my customers have that exact spec have a look at their cars and power graphs on the site.

i will do as i want that p8 kit to run all the als and coil pack ect so would it be much more laggy than a stage 3 t3

if you don't mind jano which in your experience is the best cam to go with that turbo for midrange/torque

that would be a good help i didnt even think about that my car has a piper fast road cam in....

Depends on the head and engine size really. A good allround cam shaft is a CVH35 Kent. Makes the power and also drives very well. This works well with 4x4 Compwheel and housing or larger with a .48.

Best spec with a CVH would be all steel and forged T34 with .55 or .63. CNC Head with larger valves twin springs solid lifters roller rockers CVH37 Cam. P8 Pectel board coilpack als loads of boost and MTX75 Gearbox RS16i rollbar setup. Couldnt ask for anymore.

jano well i want this turbo thats for sale but aparently im not aloud the cosworth management because my gotech is runnig just needs final mapping and i spent aload of money on a gearbox ect last week

so the turbo is a stage3 t34 nms spec with .48 rear housing -34 and i will use my autospecialists manifold / and ive got steel low comp 1600/ stage3 big valve head/ piper fast road cam / gotech mfi/ dark greens/ efi inlet / and so on its now got a cts stage 2 box and helix 6 paddle /

what sort of power levels are possible with the spec and what would be the benifit of the cam you listed and could you pm me some details of it

Versus_Creations

iTrader: (1)

I cant pm you details that you want fella.

Dont really go by stages as there is room for error, but i would expect a 4x4 compwheel and housing. With 360kit and .48 is a rough stage 3 by most companys. Id rather state what i wanted in size rather than stages.

The problem i see for big power, what i call around 300bhp in the normal mk3 mk4 car is the .48 and piper cam.

With a .63 and better cam profile i would expect better figures. I would guess around 240-250bhp depending on what boost levels you run of course.

project rs

i was always under the impression that the .48 housing was capable of near 300 (with around 2 bar) and if you wanted over the "magical" figure then you needed to swap to one of the 2 other housings, have you by any chance tried any of the newman cams or do you prefer the kent profiles i've always liked the cvh 34 not done too much with the 35 but have one knocking about somewhere

I also think a .48 on a T34 will do 300bhp, .63 will come on boost at like 5500rpm!! Remeber D4 RST's first graph? That was on a .63 if IIRC and then Christian suggested dropping back to the .48 to derease spool up time, which is what they did in the end.

Wonder what happened to that person and car

well im not bothered what boost i have to run but i want around 280bhp as otherwise if its only 250bhp i might aswel stick with the t3 ive got lol.....

but i want a bigger cam to match...

On the 1600 a .48 runs out of flow unless the head is really good design or its using the cosworth Yb .48 as this flows better too.

The .55 is perfect but very hard to find.

rsmark86

iTrader: (3)

o well thats poo as ive said i will have it but i have a fully done out bottom end and a stage 3 big valve head ....

so if i get the kent cvh37k with solid lifters ect would i get close to the figure i want (280bhp)

Probly not without a larger front end on the turbo or more boost than the Turbo would be happy with. You can never say 100% till you try, at that point its down to how well the engine has been put together with the right components and the right CR etc. If the maths hasnt been done, and just an engine has been built with decent components. Then all you have is a strong engine, but maybe not the best to make the power.

On the high power CVH engines i build i dont use the Ford connecting rod, or length. I use a similar type rod from another engine and BDA pistons from Cosworth. This ends up being really low comp and requires the deck machined to gain the correct CR. With a std crank it produces 270+bhp/280lbft with a T34 and .63 with lots more boost left to go but rarely needed due to that power being more than enough. So everything works easy and no stress on any component/s.

I missed this before, sorry. I was just having another read to catch up and noticed it.

The camshaft debate is always a good one who's best and why etc. IIMO Kent and Newman have always supplied decent cams. The way to tell which one is best comes down to each engine and what it is built for. Not a fan on the CVH34 could get the same results from a std cam with it dial'd in properly. In genral the CVH35-37 has always worked well and provided the power used with Solid Kent lifters that have never given me issues. The Newman cams i have never had an issue with either, but i do have a solid lifter from a set that does have an issue. As long as aftersales is as good with them as it is with Kent i would be happy to still advise people of using them as i have done many years.

.48 Housing.. No doubt with 2bar of boost the .48 would flow the "magical" figure on a cvh lol. Id rather have a little more lag and have some more torque to pull it through. The same housing on a YB would produce that power but when bolted to a CVH it is not as free flowing due to the head and exhaust manifold. (YB one of course) If compared to a T3 setup .48 i dont think it could make that power.

The .63 is well known for its lag however the RS500 Type .63 which comes on some lancia's, looks the same as the normal T3 Ex housing. Has a restrictive flow compared to the YB .63 Style. NOT on the YB tho only on the CVH again due to head and manifold. This has slightly less lag for reasons i cant explain with showing the map of the turbo housings in comparison. I know from a back to back test with both types on a T34 the rpm for spool up was reduced from memory around 400rpm which isnt that much but every bit counts when pushing more than the average engine.

When talking high power fuel is just as important as the rest of it, i run out of fuel with 18-20psi on Green 803's on my engine. I would need Greys for more power or light blues etc. this is down to the head. If it was a ZT then it would be different as that flows much better in std form than a run of the mill uprated 8v.

So your back to value for money. Costs the same to build a decent ZT that can make 300bhp without stressing. For the cost of a REALLY good head and cam setup for the CVH you could build a whole ZT engine.

well guys what would be the difference between a stage3 t3 rst turbo and the one im getting its got....

.48 rear housing with cosworth down pipe made to fit....
its stage3 spec t34 hybrid (nms stage6 300bhp)( http://www.norrismotorsport.co.uk/index2.html as it was fitted at stage 6)
with all the 360 bearing and all the trimings ect this turbo was on ollies nms red s1 ....

my engine spec is as follows
1600cvh
fully reworked and balanced crank with acl bearings and arp bolts
pec steel rods and low comp woszner pistons +.5 ect
fully lighten and balanced bottom end and arp bolts throught out
genuine gaskets throughout
stage 3 big valve head with both exhaust and inlet sides ported
fully ported inlet and adator plate
billet fuel rail fitted with pressure reg
803 dark greens but ive got a set of siemens black 55lbs and a set of grey ready
piper 285 cam kit but im saving for a cvh37 with solid lifters ect
adjustable pully
airtech rad
airtech front mount
air tech breather kit
autospecialists tubular manifold kit

and then the turbos listed above

its also running gotech mfi with custom braided loom

Jano can you PM me a number mate, interested in a few things from you, clearly you can't advertise on here so i will only need 'advice' lol specifically about this

And if you know of any company that can supply the above.


Rob,

project rs

rsmark the only real difference is lag which the t34 being bigger will be slightly more but once in power band will not experience it again till you drop out of it and you need a better intercooler and jano i currently run greys on mine as i also ran out of fuel around 18psi but i'm also on a one of cam at moment that were trialing to see what it can do and so far seems to do the bizz but as you say better to build a full zt for reliability and costs as thats the way forward and am collecting bits as we speak just need a spare Ł750 for some nice american kits i seen on oddkins site

wicked mate so just a nice hard launch in first and away i go lol

well im getting the turbo tomorrow , so my airtech front mount aint any good then because their fiesta is over 300bhp with airtech cooler.... but whats the best to get grs? ive seen one for sale second hand so will try for that but i want the 6 pot brakes that are for sale on here

Karlos G

iTrader: (4)

I've always heard and seen good results on Airtech coolers, but.... not see one on a 300bhp car.
Radtec or GRS are proven IC's for big power.

rsmark86

iTrader: (3)

their fiesta is a 2.1 zvh fitted with gt30 and aftermarket management and its over 300bhp.....

but im going to go with the tried and tested to be safe so i want a grs cooler and massive fan like odd kidds

This is not possible on this site Rob, there are plenty other ones that have no issue with me giving you advise and quotes on etc. Im here to anwser questions and maybe ask a couple as and when Hope you understand.

just picked my turbo up and im fitting this weekend .... it was fitted to the engine and p8 thats for sale on here and was running 289bhp on greens ect but the injectors were maxed .... so a mate has offered me a set of siemens black injectors (55lbs) cheap and they are brand new so i will use them.....

he had a newman phase 4 cam kit and ive got a piper fast road cam so i wont quite get what he had but i would be happy with around 265/270bhp as it will still be bloody quick. and then i will save up for a cam kit and jamsport inlet and exhaust manifold
