Right before i start stripping my t34 and 55's to be replaced by a t38 and 83's is it going to be worth it, seems alot of fucking about for what may only be an extra 50-60bhp? correct me if im wrong, piston cut outs, different valve spring, bd16 then there the hassle of gettin it down south to be mapped...

read a few post about this people sayin a well set up t34 is just as good, wont get the use of the t38 until 4th gear etc.

need to ask the questions myself to make a decision, any help would be appreciated,

thanks

Defo worth it with correct supporting mods, easy 450 turbo

Why not look into a gt30? Less lag and more flow in most cases.
Worth it? If you need more power then yes.

damn dont bring cossie4i into this as it will be pringles time again, must come to down to what you want out of the car or if you want to chase numbers as its the road to ruin

rs_traynor

whats the correct mods for a t38 to get 450bhp?

have thought about a gt30 can this be run on bd10's? just a case of change turbo and injectors?

the car runs spot on at the moment, does what its ment to do, dont wanna loss that but wouldnt mind sayin iv got a 450bhp cossie, dont want to start changing stuff the regret it cause it ran perfect on the t34

its been playing on my mind for a few month now but really need to make my mind up

GT series or T4 on 83's min then a decent cooler, inlet and map job done - i wouldn't bother with a T38 i've had one and it was ok, on the wrong spec motor - since having the GT and the right build and it's pretty lively more than enough for me

rs_traynor

james its only on the road 6 month of the year and then its only out at the weekend if its a good day or if theres a meet/show on definately not bored of it still puts a big grin on my face everytime i get in it...

this is what i mean buy dunno if its worth fuckin around with this set up.

rs_traynor

its all decent stuff on it chris, what cams and inlet you running?

keep sayin stuff it im goin for it then come to it and i change my mind dunno what to do to be honest

I know your car and Spec pretty well from when Paul owned it, it's got most of the it's on it tbh, I'd think about a GTX3071 too if I were you that's if you're DEFO going to change your spec, what cooler is on it as I can't remember

rs_traynor

its got a pro alloy cooler mate, just looking for advice on whats best... cause i know it not just a case of bolting on a turbo and away you go

Staffi

iTrader: (1)

Well GT range you can go Internally, or Externally gated, difference in price and more power too.

Personally if the current setup still gives you a buzz as you say then I'd leave it, saying that a GT setup will ALSO give you a great car too

rs_traynor

seems a bit stupid really as i hardly drive the thing so to spend all that money for something to only get used on the road for a handfull of times in 6 month is crazy... time to punt this turbo on i think minds made up defo not changing it.......

.................in the mean time llf

If the car goes well and is reliable, I'd leave it alone and enjoy it.

If I'd known back when I started building my car what I know now, I would've left mine at the spec it was, just rebuilt the engine and enjoyed it.

As a couple have already said, chasing numbers is a pricey game to play as I've found out!

Saying that I did love mine on a T38! Basic engine was standard apart from a ported head, grey injectors and the usual gear, went well for what it was and nigh on indestructible!!!

BD16+ inlet cam & Hart manifold plenum

rs_traynor

did you have to get valve cut outs in the pistons? or just harder valve springs?

BRAMMER

iTrader: (23)

I had a complete new long studded 200 engine built with pocketed pistons, fully balanced internals etc rebuilt ported top end with BD08 & BD16+ cams, Hart inlet, GT3076r internal gate.

Me neither chop, brilliant turbo imo.

What's point... Even on another thread ages ago Steve was saying he'd ruined it... Oh the lag... Not for me thanks... T34 fully usable and reliable and drive lovely round town...

iTrader: (15)

To be totally honest with you my car was at its best and most reliable on a T34.55, light head work 400s and a 4x4 inlet, made 372bhp.

The TT T38 only had a slight extra bit of lag when coming on boost but if you was on it you didn't notice. Yes the car pulls a lot harder at the top end with the T38 but to be honest i doubt you would notice around the lanes only on a main road/motorway.

Good honest answer there big man

rs_traynor

thats what im thinkin mat why change it if its running spot on.

iTrader: (4)

Cam and GT30 on that engine would be mega, saying that a T38 and a re-map would do the job.

rs_traynor

thanks for that mate, my minds made up i think... no point changing it if im happy with what it does pulls all the way to 5th gear limiter good enough for me

thanks

Rsmat

iTrader: (2)

Good man...!

rs_traynor

dunno what to do so just gona leave it at the moment.

Staffi

iTrader: (1)

I will say this and this is just me as everyone knows I like to spend with it having the 200 block, head work etc I'd defo have to wack a GT30 on it tbh

GTX3071 would be a hoot

rs_traynor

right ok so if i did go down the gt30 route with my current head work etc is it just a case of fitting a cam, turbo, injectors and a map? only thing thats worrying me is if i fit a bd16 cam will the pistons need work thats if they aint already done or will i get away with harder valve springs? been reading mixed reviews just want whats best if i do decide to take the leap.

If its not broke....leave it alone!

i went from a t34.48 to a turbo technics t38 and was a massive difference. i wish id have left the t38 on and not spent nearly 3k on a gt30 . the difference compared to a mates t34 car was very noticable.. on the motorway that is tho..

rs_traynor

think your right paul its getting left

Karl 3dr

iTrader: (9)

I did the same swap and loved my TT T38, my engine wasn't specced right for it either so with headwork etc I would think they're awesome, depends what you want to use it for really, if you're happy with it I'd leave it mate

james kiely

iTrader: (5)

if you brake the t34 ,then change it mate

im definatley sticking to a t34 /48 and a 3.9 diff ,
