T38 spec discussion/advice
As i hadn't got a turbo on the car i decided to take a step further and go for a T38.
The current spec is level 1 with MSD chip, standard rebuilt engine (according to last owner) that's covered 3000 miles, was a T34 .48, 803's.
I have a L6 ECU, 403's and my cylinder head will shortly be going away to be worked.
What cam specification for this set-up would be right?? i have heard that only one cam is needed, a BD14 inlet???

On my 4x4 saph at the mo i'm running a similar setup ie, standard bottom end, grey injectors, T38 turbo, ported and polished head but with level 8 ecu and a few other bits likke wasted spark etc and with standard cams it put out 450 bhp on the rollers with 390 ib/ft of torque.
The only slight criticism i have on this setup is, due to the standard inlet cam, when you are cruising with the boost on the highest setting (about 28 psi), when you just put your foot down to accelerate from cruising speed, it does have a tendency to boost surge a bit. I can get round it by dropping a gear a two to get the engine turning over that bit quicker and then it doesnt surge at all.
I have spoken to my tuner about this and I suggested fitting a bd10 inlet cam to sort out a bit but he said it would make little or no difference and probably lose me some power.
I cant go for anything bigger due to having no valve cut outs in the pistons.
Other than that, I find it all works quite nicely!

As far as i'm aware the bottom end is standard, i will call the guy who built it and try and get as much info as possible but i have a feeling he's going to say standard.
So kitchen devil it does all work well together then?? mine will be near the same the only difference is the level of ECU.

Yeah i think it works pretty well other than the surge issue i mentioned but if you change down a gear and get the engine spinning quicker, you shouldnt have much of a problem.
Ive been thrashing the arse off mine and its been pretty good! (he says touching a large piece of wood! lol!)

maybe something to bring into the equation here, which of the variants of the T38 are you going for?
theres the Turbo Technics T38 item, which is more or less visually a T4 face on, where as the Universal Turbo T38 resembles a T34.63, unless you know what your looking at on the inside!

Cool, just didnt want you both to be talking about different variants of the T38 and be confused if it all didnt work out the way you had hope.
My old engine, other than having mildly lower compression, was standard head and cams on a UT T38 and greys, for me it was awesome with no known surge or stalling.
all setup on a chip suplied by Steve Scott, and runing airs as boost contol.
Mine was peeking at 35 - 36psi and holding 30 - 32psi, and it had the 36psi easily before 3500rpm.

it was a tt38 with slightly ported head bd10 cams 2wd maifolds 500cooler
it was 385bhp 416lbft serously fast car nothing would touch it round my way, i reacon i might done a gt3 porche on a good road as there only 340lbft and 385bhp, it only had a off the shelf chip from stu, could be arsed to get it live mapped.. sold it now but if it had a 4x4 inlet manifold it would of improved the bhp to 400+ but may have lost torque. who knows....

personaly i use msd stuff and wouldnt budge, things like there closed loop chip, wasted spark, there spark plugs, fan switch. as the stuff they sell works for everyday driving. i cant stand poor running cosworths that you can't use properly, there not worth having... i ripped out a complete omex 600 ecu and put back in a l8 ecu with all the msd bits in and it transformed my car its runs 50times better. starts straight away ive been using it at 6 in the mornin,g for work, even tho its got inch solid ice all over the bonnet and window, it still warms up like a modern mondeo....
