i have an st turbo and im going to change to large turbo, hopefully soon, i kno i have to chane the ecu system to an omex 600 or autotronic or something, but before i have it fitted and mapped i have to fit everythiing else. but i dont kno what too get and i wanna run around 400bhp,

current spec (engine rebuilt 4k ago harvey gibbs)

-low comps machined valve cut outs
-mild port and polish head
-rs 500 intercooler
-ggr 305 bhp kit.

im going to get a tubular manifold, but i dont kno what turbo, cams or injectors too get, any advice would be greatfull guys !!!

 

id say firstly you dont need to run Autronic or Omex.
you could easily run it on L8 or P8 with no drama's. in fact id personally run it on L8 if i were in your shoes.

why are you going for a tubular manifold?

if your only after 400bhp then a T34 would possibly do you good, or maybe even go for a UT T38!

 

l8 is the older ecu's right? im not too clued up on that stuff thats why i just thought it would be easier to get a new system installed? whats a ut t38 turbo then??

 

UT 38 =
hybrid turbo build from a T34 turbo.

but a t34 stage 3 with 360° bearings and cut back blades will suit up to 430 bhp normally, with low lag.
also need an big turbo manifold

you can go different ways:

first:
l8 ecu/P8 ecu with software (several dealers carry that) for that (grey injectors) incl. Weber Marelli loom engine sided, then you ll need a big turbo throttle body also, because the small turbo manifold won't work with that ecu (without modification to the TB)

second:
Go for an aftermarket ecu like Omex, Autronics, DTA or so...
get a bigger turbo, get everything mapped...

 

i think i will go the omex or autotronic way i think guys when the time comes? can you still run greys with those types of ecu? or go for something like seimens?

any ideas on cams guys?

 

my car runs an Omex 600 ecu, TT T38 turbo & siemens high impedence 650cc injectors, it was pulling 435bhp at 30 psi, it now has a different coil setup, bigger plug gaps, & 32psi if i want it.

 

nice!! yeah thats the sort of results i want,

where did you get you omex 600 fitted and mapped too? also how much lol

 

do you want to keep the std loom or are you wanting a new engine loom

 

Hi, we fitted it at Torque of the Devil, Matt got a special price as he was a mate, (but is now a serious threat ) but to supply fit and map a similar set up would cost Ł1600 for the omex 600 system or Ł1800 for the omex 700 full spec system, both plus the dreaded VAT im afraid.

I'm sure Stu@Motorsport developments can do this conversion with the stock ECU.

liamford my car has been getting some bits altered on the map recently, in the near future i will have some good options for small turbo escos owners.

 

BANG ON!!

you dont even need to change the ECU stu can map this no probs give him a call before you go shelling out for ECU's and looms ect

 

has this conversion been fine tuned yet? I'm sure its still in the development stage?
