Tuning question

[Mongo]

Hi all just curious if i fit n/a (glt) cams in my t5 is it a direct fit just buy 2cams and time them? Same sensor ect…
Also t5 intercooler ive heard there very good and wonderd what sort of power they start struggling? If i said high 300 low 400 horses will it cope or isit a dead end question.

[Volvostorm]

Yup, the cams fit, and work the same sensors.

I believe the standard intercooler is good for the mid 300s, but, uif you can find an uprated one, go for it.

Aw gdgd im goin for low 400bhp iv bought internals turbo ecu injectors ive shotguned a 3 1/2 inch exhaust off of a getleman called niles should get me there.

What turbo have you bought?

[Mongo]

Garrett T3/t4e dual bearing rated to 450-500hp

[t5_monkey]

A good custom intercooler is important, don't skimp on that! esp if you're going for big power.

if i go for GLT cams do i have to alter anything or is it just old ones out new ones in simple as that or is there shimmin involved?

Straight fit, the timing slots line up in the same place too.

[woz]

what i dont get is why, if the N/A cams are so much better, then why did Volvo not use them in the first place?

I expect there is a good engineering reason. Does anyone know what it is>?

Maybe something to do with emission controls ?

why didn't they fit 19t's to everything in the first place? Who knows

Yeah thats a good question too!!W:>)

[Volvostorm]

Or Garrett's!

Many moons ago I had as Fiat Uno turbo, the engine was tuned like mad. Pushed 175bhp @the wheels on a very reliable rolling road power run. The cams in the Uno turbo were quite mild. If you took the cams from an Uno SX (sporty but not turbo'd) the power band was lifted & the car gained 15+ bhp in an instant. Hotter cams to help lift the power output without the turbo.
I think the milder cams were put in to make the car more driver friendly.

[Yorkshiresxi]

so has many people done this mod with the cams? is it worth doing or is it easier to buy some piper or other aftermarket cams?

[Mongo]

Think it realy depends how much you want to spend. I think if you pay the extra for the aftermarket ones you might see better gains but i dout itl be much more than the N/a volvo ones.

[Volvostorm]

I'll let you know once mine is running, I have Piper's in it :)

[p fandango]

GLT
Intake:250dr duration 0.332 inch lift
Exhaust:252,6dr duration 0.332 inch lift

T5
Intake:242dr duration 0.312 inch lift
Exhaust:243,5dr duration 0.312 inch lift

Piper
Intake:248dr duration 0.348 inch lift
Exhaust:248dr duration 0.310 inch lift

[Volvostorm]

So slightly short duration, but with more lift, but less lift on the exhaust, hmmmmm

[p fandango]

i did ask which is better duration or lift a while ago but got no reply :(

i'm thinking Piper intake with GLT exhaust cams :)

[Yorkshiresxi]

what about a volvo s70 ( r reg ) non turbo..2.3 i guess it is..just i know wheres theres a full engine waiting to be broke.would they be the same?

[Volvostorm]

i did ask which is better duration or lift a while ago but got no reply

I've found this:

With a turbocharged engine, more lift and duration is needed on the intake valve to prevent backpressure (created by the turbo) from backing up into the cylinder.

Taken from: http://www.aa1car.com/library/supercharge.htm

and also:

Typically turbocharged engines have lower lift and less duration than their n/a versions. There are sound reasons for this. Using hot cams on a turbo can easily result in power losses all over the rev range. Lose - lose situation! This doesn't mean that cams 'hotter' than stock cannot work properly, of course they can - but cams that are considered as 'race spec' for n/a versions of an engine will not work well at all with the turbo. And here lies an opportunity: the stock cams of the n/a version of our engine will quite probably be as hot as we want them for the turbo.

I guess Piper know what they are doing

[T4Rick]

So n/a cams are the way forward lol i have a 2.5 n/a engine in the back yard lol

Its not going to hurt :)

[Yorkshiresxi]

So if this s70 is a 2.4 then and the cams are a couple of quid there worth getting?

[T4Rick]

What even if i upgrade turbos in the future.There was a bloke on 30forty50.com who has done this to his t4 and he is running 500 plus bhp with n/a cams.I was under the impression that your car had to be a bit on the wild side to use n/a cams on the turbo application lol

[Volvostorm]

I've not idea about the 2.4, as that uses VVT on one of the cams

All this info is 2.3 based

[T4Rick]

I dont have vvt paul this is a 1995 engine

[p fandango]

I dont have vvt paul this is a 1995 engine
he weren't talking to you ;)

[Yorkshiresxi]

ok so if its a 2.3 im ok. :-) trip to scappy monday then

[Volvostorm]

I dont have vvt paul this is a 1995 engine

I think we have all got a bit mixed up! :confused:

[T4Rick]

he weren't talking to you ;)

Oh sorry lol.So will be ok using 2.5 n/a cams from a 1995 engine

[Volvostorm]

Yes mate, as long as they come out of a 20v ;)

[T4Rick]

Nice i have a spare head that im gonna play with at some point,plenty of porting see how far i can take the head then get it flow benched

[Volvostorm]

That is the biggest problem with these engines, they don't flow well :(

Mine's had a mild porting job done, probably makes no difference!

[T4Rick]

I was thinking going heavy with the porting lol

[Volvostorm]

Watch how deep you go, I believe the water jacket isn't that far away.

[T4Rick]

I will but i wont be touching it for a long while got a list of things to do

[smithy]

when i had my v70 2.5t i built a new engine for it using s60r pistons and conrods in a 2.435 block and i fitted 2.5 n/a cams because i was using a t35 hybrid turbo and from 3k the car was a animal and was only running 1.3 bar at the time too but was goiung to up the boost to 1.6 bar.i think n/a cams are work fitting if using a big turbo but no point if using standard turbo.

[T4Rick]

Dont they use the t35 on the cossie or is that the t34.what manifold are you using smithy to use the turbo.Also what adjustments did you make for the oil lines

[Jamest5r]

The T35 is a mix of a cossie compresor wheel and a pulsar exhaust wheel matted to a s60r mani and was designed by turbo technics to fit in the volvo bulkhead. The oil/water lines have to be adapted, it's now on my 850 :)

[8501970]

Does anyone in the uk run a GT40 or bigger ?

[p fandango]

i emailed a company breaking a 850 NA on ebay asking about the price for the cams, wanted £80 lol. I'd prefer to pay the extra & get new Pipers if thats the price there going for

[Mongo]

Niles has got the n/a and 3.0l throttle body for sale.
