hi everyone, i need your advice on what turbo is best for my 2wd 400bhp and 450bhp, ill be runnign greys, new clutch, diff,group a oil pump etc etc, low comp pistons and cams too.

On other posts people say that a t34 is only good for 380bhp and that was what i was going to use originally, but it seems that it wil not be powerfull emough.

I want a 400-450bhp set up so i need other suggestions to take the place of a T34.

Cheers people

Luke

 

Luke get your self a t38


cheeRS stu

 

T38

 

so whats the diff between a t38 and t34? and what size should i llok to get?eg .63 etc etc?

what are the power range of a t38 then??

cheers for your help

Luke

 

would the t38 still run on greys then? and would i have to do anything else to the engine other than low comp pistons and cams? any suggestions on bits i need would be a massive help!

cheers

Luke

 

T38 would still run on Greys it gives you more top end than the T34 would, it just keeps pulling, mind you T34s with .63 housing aren`t slouches

Are you just going for numbers, or do you want a nice, no lag drive car?

 

HI STAFFI,

at the mo im just going for figures, im hoping to only use it as my weekend car, its only 280bhp at the mo which is why i can use it everyday, but its getting me and the car down only doing half the speed limit to work every day! lol

would the t38 reach 500bhp??

also what engine upgrades do i need like cow comp, cams etc etc, could you give me details on what i need to buy as there are so many possibilities and 450bhp is out of my knowledge range!

cheers folks!

 

T38 500......NO

GT30, OR T4.......Low comp, not nec for 450/ Clutch/ head gasket/feul pump/head work..........brakes

Go to this link oh, and a nice bank manager

Just out of interest, why are you after numbers, a well set up stage3 car is aewsome to what you have now dont get carried away with the magic 500 its nice, but you will need alot of pennies

yer i no mate, ive already broght half of it, i just need tubo injectors chip and ecu,

stage 3 would be nice but thats easy to do and everyone is running that, to be honest i dont even think it would bring a smile to my face, i want a unique car, stage 1 bores me, it doesnt even throw me back in the seat anymore,

i would like 450bhp that would comprimise power torque and drivability, are u sure i dont need cams or anything? so just need head gasket and also to skim the head yer? anything else mate?

Luke

 

Yes cams and verniers

Where are you in the country?

And who is building your engine? or are you doing it yourself?

 

im in kent down in dover, and im not getting an engine rebuilt, im using the standard bottom end, just put in some cams and vernier pulleys then.

i got a quality mechanic from turbosport forums helping me out, do u htink i need a whole new engine rebuild for 450 then??

 

You said on a reply higher up your using low-comp pistons

And now you say your using standard bottom end

As said above its a big job getting 450-500 bhp

Your goin to need bigger injectors than greys for a start m8,they max at 430bhp

 

yer cheers for the greys advice, im not to sure about about everything yet, some people say i need to rebuild the engine but i think for 450 i wouldnt need doing much work to it would i

so greys max at 430, what would i need to do to the engine then mate? all help is appreciated

 

200 block but i would i have seen 205s go to 500 bhp cossie cranks are good for 600 bhp if in good con rods 450 to 500 if same i would do new bearings to and as said you will need more than greys they you will new a diffrent ecu as above not cheap to go 450 bhp 380 is a very nikce power in a rwd cossie

 

Agree totally with DAN.....380 is a great road car......

As i said above, for some reason your chasing figures

I wish you could come and have a drive of mine, you might change your mind

Im not saying that 450-500 isn`t awesome cus it is, but 380 isn`t a slouch either

 

450 500 bhp on the road is not needed i dont think unless its 4wd but iv never drivin or been in a 450 bhp rwd cossie so i cant say been in a 560 bhp escos that was set up buy mr norris and all i can say is 2.2 bar on a gt30 is fooking mint

 

its alot harder to get anywhere near the magic 450-500 barrier than just choosing a turbo and injectors..

the car needs to be converted as a whole or its a waste of time...

the suspension, brakes will need looked at...

nothing under my bonnet is original....

apart from the crank

 

hi all, im sure 380 is a great road car, but i just want that extra bit more and im willing to pay the extra bit for it

The reason why im changing my figures from say 400 to 450 to 500bhp as im not sure thhe minitations of each bit of kit, such as the injectors, t38 standard parts int he engine, i would love 450bhp and only use it at the weekend and start taken it to the track days and club meets etc etc.

so there have been a lot of info on upgrade to internal parts of thestandard engine,

just to clarify, please could you list the engine mods for 400 bhp, and the engine mods for 450bhp. not includinging things like swirl pots, breather systems etc etc, just the engine internals.

ive already sorted the diff and clutch and ill need to upgrade the brakes, there already upgraded but ill need bigger ones!

cheers for everyones help

much appreciated

Luke

 

t38 injectors i dont think you can push greys to 450 and then i think you need better than l6 ecu cams are good to 400 so bd14s or 16s 450 engine rebuild pullys and a few more mods lol

 

cheers dan

so anyone got a price for me for an engine rebuild then??

 

I find it very strange why your wanting to go from 280 bhp straight to 400/450, obviously your already not 100% on these cars as you wouldnt be asking the question so why not just go for a decent stg3 set up, my car was 260bhp when i just got it, now i`d say its a genuine 330/350 and i can tell you the differance is very large, you going from 280 to 450 is not needed, but everyone to them selves an all that, good luck whatever you do and mind and keep us posted on the outcome

 

Hi Mate,
just going on what the other guys are saying, that is a hell of a jump in power output and I cant help but feel that would be hard work using that on a regular basis as a road car.

A friend of mine had a 450 bhp 2wd and that drove like a pig round town where as my stage 3 would leave him for dead on normal roads and the twisty stuff just because it had better driveability. However out on the open road above 70 mph with more than 4000 rpm it flew! Also very scary as well especially when the back used to try and overtake the front on anything but a bone dry road!!! Not forgetting his 8-10 miles to the gallon of super unleaded! That power dont come cheap!

If you like a lot of turbo lag thats fine but you will be seen off by other cars with a lot less power while you are waiting for the turbo to spool up and by which time they will be long way in front and you!

Also getting the transmission to cope with that amount of power is going to be a constant problem, not knowing when its all going to go off with a bang.

A well set up 380 bhp car is, as said previously is as good as you could really want for a road use.

Your choice I know, Big power is good to talk about down the pub and great for a track car but for normal road use I wouldnt part with mine in.

CheeRS, Mike.

 

Mr Duke
I am in the process of upping my power at the moment and its proving to be pretty pricey since i have decided to do so.

I have even changed my original plans of upping my 3dr's stage 3 power and sticking all the goodies on a track orintated saph (3drs to clean/original..bufty in other words).

i would recommend finding someone with a well set up stage 3 car to give you a spin and see the diffrence from your stage one. You may be surprised.


If that doesnt float your boat just go mental and spend a fortune its great fun

cant wait till i get home

 

Been in a 560bhp ish 4x4 cossie(norris designs built engine)thats on low boost 632 bhp i think

Absolutely awsome

 

Hi Mate...

SCS do a t38 based conversion, I think it maxes the greys out and produces 450bhp but more importantly drives really well with far less lag than a 530 t4 conversion. As the above guys have said it is important to keep lag to a minimum for a great road car....

Cheers Malc

 

hi, cheers for your help, do you have a contact number for SCS then?, im staryignt o agree with everyone and think i might opt for 380bhp, im still getting prices and tech info for 380bhp and 450 bhp.

But ill let everyone know as soon as i know!lol

Cheers

Luke

 

At last

 

cheers for all your help, ill do a deal with everyone then, ill set it up for 380bhp, and if its still not fast enough then ill be interested in 450bhp

so does anyone have any product suggestions for 380bhp, like what works best with what etc etc?

luke

 

For 380 I think most people will say T34.63 & Greys.

 

If you get it setup correctly, trust me you want be dissapointed

 

so t38 greys, head gasket,clutch diff etc etc, anything else i need to do to the internal engine apart from head gasket and getting it skimmed?????

Luke

 

good head gasket and that should do it m8 if the rest of the engine is in good nick

 

yer well ill found that out soon enough, fingers crossed though! i was thinking of getting my engine rebuilt, say the top half for the 380bhp and maybee when i upgrade to 450 bhp get the bottom half done.

So i dont spend all that cash at once!

But i what i dont want to happen is to spend money on say a diff and clutch then have to spend more money on the same parts when ui upgrade from 380-450,does that make sence????!!!! lol

 

pistons rebore rings bearings gaskets oil pump water pump rebore poilished crank if your lucky head skimed head gasket valve stems guids alcon 6 paddle clutch gripper or atb diff

Cheers for evryones help, one last question, the t34.63 is good for 380 but if i wanted 450 i'd need a t38, could i use a t38.55 or something to keep lag to a minimum or would there still be so much lagg with a t38 running 380bhp??

As i want to try to avoid buying one new t34 turbo, then selling it for a t38 and loosing loadsa cash!!???!!

 

IMO I wouldn`t bother with a T38, i`d go straight to a GT30, bit more dosh i know, but great turbo, will see 450 all day with not alot of lag at all

 

yer but would that turbo be suitable for only 380bhp too?im just tinking of lag etc??

 

Not really, but aT38 isn`t needed for 380....

A T34 with a 63 housing would be fine

 

Cheap used T34s come up for sale here all the time, it's where I got mine.

 

cheers for advice peeps, im hoping ot get some engine bits done next sat if there is one decent garage open while england is on!

lol
