Mad Ade's 700 bhp gt35 2.0l YB discuss here
that's ok if you want to go that way, but a year or so ago it was all about a gt35 until users started taking them off and putting a gt30 on because of the lag or surge now it's a gt3071 or 76 or gtx or whatever else tbh i can't be bothered with the agro of possibly making a mistake and buying a surge monster

I will hopefully go out in Jb's at some point but I was asking about a billet wheel for the t4 that I have fitted already 
I ran my car on the rollers and it put out 449bhp at 27.5psi (boost gauge reads 30psi
) but the torque was low at 375lbs which was dissapointing but I think it is the exhaust cam and the lack of boost which are easily fixed a billet wheel would be a nice addition.

but to hole gt30 /gt35 thing being laggy and surgy is a myth its all down to bad cams and mapping!

the gt3071 is fine the gt3076 is ok but laggy
the gt35 is not suitable for a 2litre yb with standard bore stroke ratio
the compressor trim is to big for a 2l yb
why redesign the engine to suit the wrong spec turbo it is far easier to use the right spec turbo in the first place
bad mapping and cams indeed

the only point I'm makeing is some these lastest threads seem to make gt3076/gt35 turbos out to be laggy surge monsters that are not very good I'm just saying that's not the case!

I'm obviously no expert but I changed from the tt t38 to a gt3076 and if anything the new turbo is far less laggy and more responsive than the t38.
Although when mapped first on the l8 felt similar to the t38 setup but since marks mapped it on autronic it feels like a totally different car.

I'm not knocking the T38 a good friend of mine has one on vipec and its a very fast cat but he is going to up grade to a gt30 like mine! Plus ill never agree will you saying a gt35 is laggy and surgy as I still remember when rod first did 200 on an old gt35 and that car was immensely fast off or on the gas! And deffo not laggy! Just because some tunners don't get on with them dosent make them bad turbos! And yes that engine was just over a 2l but ades car was still a 2l on a gt35 and again immensely fast and not laggy

Happily retired
Having run just about every Turbo known to man (9 different ones) I perhaps can say better than most what works & what dont.
Problem is they are moving on at an incredible rate. Garrett GTX range have not had an answer to the last 2 Borg offerings the SX range & the EFR. Im awaiting the latest EFR.
A 1956 Morris Minor worked & some still like it but things have moved on. A T4 .

The t4 is the tits of a turbo, nptheres no better engine suited to a cosworth than a t4 and 8grees rs500 plenum. That engine just IS cosworth!
As for the gt35, tony is right, shite on a 2.0l. Run baby cams might help the surge as its moving alot of air low down (as its e exhaust wheel that is the issue btw, done alot of development on the 35 with diff comp wheels years back) but its still going to have some surge.
The 3076 on the other hand is an awesome turbo (better still than the gtx 30/71-76 IMO!) they're much more responsive than a t4.
And the gt3071 is all round brilliant

Lots of people on here had a 35 when they were the new hot poop, and promptly binned them off in favour of a 30, on a std geometry engine as most people run, they probably don't work that well, hence the generalistion.

This is a t04e RS500 8 injector time team thread
piss of with your GT35
I recon the tall one will win
and I have driven both cars
John may have an elite 6 speed gearbox but he'll need everyone of them and maybe a few more to out do the tall one
My arse dyno tells me The tall ones is more powerful
Now stop high jacking Mine and 4i's ASW thread with your oversized gt35 lol
Jimbo is right a t04E is just fundamentally what a cosworth is all about
maybe I amjust old and reminisce the rs500 touring car days

You,d know more than me lol so i guess your right with the stroke being a factor as ades dose have a stroker kit! but as for the gt35 not suiting a yb thats rubbish as ades was massively fast with that turbo and was,ent laggy! fair enough its and old turbo now and there is better out there now what with the gtx range and developments in twin scroll with borg warner 
. But as for redesigning the engine to use the wronge turbo lol if your going for big power any way your going to change the pistons so its not hard to change the rods and go stroker is it so why waste your time with an old t4 turbo thats trying to be modden you may as well move with the times

As for ades car I've no doubt it's awesome, when moving, like you say as its on boost, but driving a awesome specced yb wi a gt35 at 4500 the boost has to be capped due to surge. Changed the turbo and the engine was absolutely awesome. Tell me how that is so if the gt35 isn't the issue but poor cams and mapping lol

Really. The new owner of our old car has the escos road legal, runs on race fuel at 798bhp and has a 6speed sequential FFD now, I'd like to see it keep up 'on the road'. be going by at 170 as it would be on the limiter
Oh and it does 2.5 to 60 and puts power down it first gear.
I'm guessing you meant motorway and not road though now
