Hope to get my car back for running in soon before the car came off the road a year ago i had just fitted a UT T38 , im planning on running in the car with this fitted but for a road car with some 1/4 use what would be best T38 or T4 ?
Im thinking of mibi going for one of the new roller T4's but is it money for nuthing, whats the most power to be had from a T38 ?

david

Neil just ask yourself this, do you want to be associated with those two sluts, namely Euan and Colin and their T4's ?????????

Life doesn't have to be like that...................

dovboy

go t4,i no peaple say they are laggy but i found if you kept it up the revs it wasnt that bad.

t38 450-470bhp maybe?not sure

Pete Neville's old setup on a UT T38 made 450bhp.

No idea what power mine made when on its UT T38, but it used to compete very nicely against a friends 440bhp 3dr on a GT30.

then Dave Moss's on a TT T38 made 466bhp.


i used to love the way mine used to drive and the characteristic's of the engine suited my driving style perfectly.

i know that doesnt compare against a T4, but gives my view, id gladly go back to what i had before if i had to

Realy need to get out in Euans car at some point to see what this new T4 is like , i know the rest of the car spec is more than up to it. Just dont want to get it mapped then wish i had of went for the T4. So looking at 450 on the T38 and 500+ on a T4.

dovboy

what gearbox you going for neil?

david

Neil, you and I both mate

is your spec not slightly higher than Euan's ?

NEIL A

iTrader: (6)

Yip mine has arrow rods, big valve head with ferrera valves, titainium retainers and mountune wrc spec block But wont have a custom exhauset or airbox , will either run an adaptor to standard box or sheilded cone filter if i go T4 with 100mm inlet.

NEIL A

Will be sending my spare box to Martin when he re opens for mullit treatment, got a thickwall plated front diff and mullit spec rear aswell.

david

Very nice

can you get a hold of another wrc block ? was thinking one of them or an eeciv complete engine for what I want but really don't need.

does make a good life though dave eh?


neil frasers esco on t38 is fekn quick

fire through one day and we`l both get you out for a blast although in the dry would be a good comparison


mine lights the tyres up in 5th at 4.5rpm which isnt too clever

dovboy

perfec,you will need it!
with that spec engine and uprated box n diffs you might aswell go t4 because lets face it you will only do it later anyway

NEIL A

iTrader: (6)

David think mountune still do them but your looking at about 2K + or nearer 4 for the full linered version. I got mine from Dumped after he scrapped the twin turbo project along with the fancy spec head.

NEIL A

iTrader: (6)

Thanks for that Colin that would be good , get something to compare .

david

Col your a dirty whorebag, don't even try and deny it mate

I wouldn't mind a blast in your car or even to see it go up against martins at kh would be cool

david

Not a bad price at all for what you get. maybe one day....

col cos1

iTrader: (5)

did you have a good xmas davie???

il take you for a blast no problem mate


martin who??

white 4x4saph?

david

I did mate thanks yourself ?

martin - red escos on white rfx's, no whaletail. does most of the kh day's. He runs a 520 gibbs engine on a t4. Ive been out with him a few times and it pulls well.

NEIL A

iTrader: (6)

From what Euan was saying the new bread of T4's are good think it was something like 90 bhp @3k on old and 170 @3k on new

david

He mentioned how well it pulled from low down without losing much or anything higher up but that was all he really said.

fair play though as it was his engine that CR used to test the product out on.

col cos1

iTrader: (5)

aye mate was god cheers,think i know the esco you mean

i was thinking of puting the old sierra on knockhill 2008,car goes well in a straight line in the dry

neil this new roller job sounds peak aswell,once ive got the new head,injectors and big manifold on,im thinking of maybe this route too,but to be honest my turbo performs great as is and its only done1500miles from turbo technics recon

il have to get out in euans to see what diffrence it is,as i know he holds it in right high regaurd compared to our old ones

at your spec mate id be getting the bigger turbo,yours is going to be the baws

NEIL A

iTrader: (6)

Im going through on the 7th when ava re opens to find out what the hell is hapning with my car, so will talk to alan about it then just need to sort my bill so far then go from there. I already have the inlet, large tb,big injectors and mappable ecu so will just be a turbo swap and should see around 400 atw i think.

Hmmmm. I have the UT T38 as well, Not actually run it yet as my engine is just goin back in, I am just worried by the fact that they don't make a vast amount of midrange torque, but a T4 lag is very offputting to me, love to see how a T4 to Euans spec would run on a set of less wild cams etc, I have a saff with a T4 and to be honest it's not very nice to drive at all ...

Have you considered a GT30 with an External gate? Doug Stirling raves about his

NEIL A

iTrader: (6)

Dont realy fancy the hassel of going external gate the T4 is just straight bolt on. From what i have heard the UT T38 is a realy good turbo no big boost spike but then it is better on transmission and smoother to drive.
I think the new T4 will work best with big cams and good head work or mibi have surge problems, im running the same spec cams as euan so no problems either way.

RWD_cossie_wil

iTrader: (9)

can't remeber what cams Euans running? I have the Bara box and a thickwall front diff already, so no worries on the transmission side of things .... Got a mild ported head, 25/26mm so nothing too drastic .. Will see how the T38 goes and go from there Sounds like we will need a grudge match Neil, cars sound very similar specs

sounds fun

Steve.

tabetha

I don't know if this is much use but headwork made a MONUMENTAL difference on mine and it was only a de-shroud of the inlets, same size though, best Ł275 I ever spent, no more power but the torque is unbeleivable now.
It holds peak boost 330lbft from 2200-6500rpm.
It is a T34, but 150lbft at 1500rpm.
tabetha

dovboy

i have heard peaple say that the old t4 is better on transmission due to the power+torque being made higher up the rev range and gear speed.

although kevs escort seemed to strip third gear no problem on a t4 this was after a topspeed run with a ferrari trying to pass us

Disabled Account

As said above, Universal Turbos or CR Turbos T38 gives good power (450 BHP), with a
torque figure that is "OK" in that it's unlikely to break the standard transmission.......

i love my ut t38 but i will be moving onto a t4 to get to the big 500 and as for "lag"...dont belive the hype......... .......p.s the ut t38 does kill standard boxes............

NEIL A

iTrader: (6)

When the engine was getting fitted i got a new Proalloy 60mm cooler with 3" pipework and a custom inlet/tb fitted just incase, i decided to move up from the T38 as my old set up of Pace 500 cooler and spacered 4x4 inlet would of been fine with that.

NEIL A

iTrader: (6)

Thanks for that Doug

glancy2081

people talk about lag from a t4,but a have drove a sierra 4x4 with t4 and it came on boost around the same time as my t34 escort it is not laggy like i was told it would be i would go t4 neil

NEIL A

iTrader: (6)

Think thats my main problem glancy ive never been in a car with a T4, but have heard people say they are real bad and others say its not too bad.

rapidcossie

Get the car up and running and max out the turbo you have, then have a drive in mine and see what you think.

we can also compare any data from both cars taken on the rollers etc.

A turbo swap and a few hours on the rollers to tweak the map isnt a big job so could be done at a later date

dumped

Good advise from euan - then get a bigger turbo than him!

glancy2081

a was the same neil listened to every one tell me how they were this that and the other.once a drove one though it was different story not as a had been told it was MY car will run a t4 now

rapidcossie

There is one at AVA waiting to be tested

NEIL A

iTrader: (6)

Well i will just tell alan to get it bolted on then

andrewg

not read the full post but in my experince i would say upto 450 or 550 would be my reply
