ive recently bought a 5 turbo with e.p motorsport engine stage 7 head t 25 hybrid turbo race cam very agressive ep side exhaust and many other cool bits any ideas what she could be pushing out?its got also a group a carb group a fuel pump double capacity intercooler forge dump valve fan over ride switch running aroung 16 psi
easiest way to find out is to get it on a set of rollers or even better a hub dyno
Stage 7 head
With that grp A carb fitted can be pretty sure it won't be fueling right.
Once fueled right i recon around 170bhp at 16psi, there a few bits in the spec list i would change but thats just my personal preference
on the e.p motorsport invoice i have from 2006 it says tsr 03 hybrid turbo stage 3 t 25,stage 7 head fitted,ep 05 race cam fitted group a carb fitted and set up group a fuel pump 2.5 down pipe ep side exit exhaust twin pipe on the end, what do you think ??the company used to be based in stoke the car hasnt been changed since then apperently just maintained,any adivce and thought s
As say if fueling is spot on (with grp A carb 99% aren't) at that boost pressure about 170bhp
I knew Europarts very well when they were open back in the day
so is it an ok setup then mate, what boost could i run safely ??
I wouldn't trust those grp A carbs as far as i could throw them, first thing i would be doing is checking the AFR's. Poss swap the carb for a standard one and have it jetted correctly for same boost pressure or higher if you want to go that.Originally Posted by trystan Lewis
I remember his turbo's and engine bits, recon you can safely go to 20psi or bit more once the carbs right, in present state i wouldn't raise boost pressure at all
I would remove fan override switch too and have the fan kick in as it should from factory too
how would i check the afr's ??? thanks for your advice,its good to now its come from a good source
it has a very lumpy power delivery as well around 3000 rpm it comes in hard !!!at 16 psi hard to put it down to be honest how could i smooth it out a bit ?
You'll need to have an AFR gauge fitted or at least have someone check them from here or at a rolling road, once you know what there doing then you can see what needs doing or if its ok.
The lumpy power delivery can be down to the set up or needs a good service, easiest thing to do first is the service so make sure plugs, leads, cap and rotor are in good condition
yeah they ve all been checked guess its just the set up what should the afr gauge read if its right ?
and were s the best place or brand of afr gauge to buy, thank you very much for your advice and knowledge
Idle and part throttle around 14.5 and full throttle around 12.1
Scoff on here sells a nice AEM one which comes in a 52mm size gauge, that'll work well
EFi Parts.comIdle and part throttle around 14.5 and full throttle around 12.1

awesome thanks guys
if it isnt right how hard is it to get it right ?the afr set up ??
aem 6 in 1 afr gauge,is that the one ??
as stated speak to scoff on here for one of the aem kits, alastair has covered your basic numbers your after.
if your adament of sticking with the grp a carb then i can almost cerainly guarantee the 2nd stage will be standard so would be worth opening that up to 1.2mm to start. also check to see that the 1st stage hasnt been swapped with the a/c as this was an old tuner trick makes them overfuel especially on part throttle etc
Ok ill get it checked out,do you now anyone from south Wales that could look at it ?
blast from the past.....
But M burger that's a cheap when looked at the GTTuning/BB tuning prices of old.
she goes well enough for me
i dont work for free... some tuners earn a wage, some run a workshop, others take the pi55..
Too true, back in the day I had my fingers well and truly burned by K-tec and gt tuning
the engine begs... water injection and boost set to 2 bar / 30 psi............. and you will see at least 210 bhp............... with greater torque... then it will be a quick car........ and you'll then find the Ferodo DS2500 pads the best... and the of course a set of Yokohama ao32r's all round at 28psi... with the car lowed on a full set of Gaz coilovers and dampers...........and a then a 13 second quarter mile will be achievable........great cars..hours of fun....
should see the receipt for my LOW boost turbo conversion from BBPT when previous owner had it done, just shy of 8 grand iircToo true, back in the day I had my fingers well and truly burned by K-tec and gt tuning
I have a recipt for my car from bb tuning for a yellow spec engine
2.7k
Thank god it wasn't me purchasing it
also a recipt from k-tec for an exhaust, boost hoses, and a crankcase filter :edit: a double cap cooler also.
£900
