A bit of advice whats the next step for tuning? 1.6 efi turbo,its got a ported and polished head,piper 285t2 cam,beige injectors, stg 2 chip,uprated fuel pump,front mount intercooler,-31 actuator turbo been re built with t28 internals and just had the full inlet,throttle body and cross over gas flowed too.what should i do next for a bit more power? Any replys much appreciated

 

Aftermarket management then more boost if the internals will take it

 

decent brakes lol

 

its a standard bottom end and its running a spacer plate from ferriday engineering not sure how much it will cope with its about 15psi at the moment,the engine is in good condition though its only got 30k miles on it,i wish when i bought it yrs ago id strengthend the bottom end a bit and put better pistons in,what sort of price would different management be fitted? Been looking at motorsport developments site they list a type of stg 3 chip would this be of any use to me do you think?

 

Go for new pistons and rods first then and get rid of the spacer plate

 

as abive then maybe get it live mapped at msd ?

 

is this a xr2i engine with a decomp plate?? firstly i wouldnt push it over the 15psi your running if it is,
what power are you looking for?
what are you wanting out of the car?

 

I think thats the route ill take when it all goes bang i just wanna see if there is any more to be had from it while its an this spec,its not my daily so if it breaks it can be repaired when needed

 

New rods and pistons, change the cam for a Newman item, T3 turbo and Escort RST manifold, aftermarket management with bigger injectors.

All imho of course

 

its a proper rts engine mate not a 2i engine thats been turbo'd im not realy sure what i want from it just a little bit more as last summer a red top corsa pulled past me at nearly 100 and i couldnt do anythin:-(it was embarrasing it does go well but jus want a little more,ive had my injectors cleaned and the gas flowed parts to go back on.a live map sounds good what does it actualy involve doing please

 

standard rods are only rated at 250hp at most and some brake below this figure, if your starting from scratch you wont go far wrong taking oranoco's advise

a live map involves taking it to the tuner and he would map on the road
how many miles has your engine done? strap a stage 3 t3 turbo on paddle clutch,make sure you have at least a big bearing gearbox, front mount cooler,take it to a tuner and get some bigger injectors, i reckon you could see 240+

 

if i could get to 230 or just over id be very happy,has any one had one of these live mapped?what should i expect from having this done,as th car is now its quite laggy i think when not on boost could a live map make it a little more driveable as its only realy much good when the revs are high

 

that would be down to low compression??
what is the compression ratio now??

 

thanks for explaining that i think my car could do with a live mappin session,hopefully it wil make it a bit more driveable.the engine is in excellent condition,would i need igger than beige injectors? Ive got a paddle clutch in already but still running standard 2i box so dont think it will last long although it was fine all last summer and i did a few hard launches so il keep fingers crossed for now on that

 

im not sure on the compression th plate ive got in there was to compensate for the haed having being skimmed a couple of times in its life and to just lower it a little more than std,its not mega low comp or owt im at work on phone at moment i wil find out tonight though,what should it be as std any idea?thanks for all the replys

standard compression should be about 8-3-1 or there abouts im sure someone will correct me if im wrong lol

how thick was the decomp plate you ordered

 

i think it was 2-3mm im not sure as it was about 5 years ago when i fitted it,i do remember that the head has had a fair bit off it in its life though,il try find info on it in the paper work when i get time,im wondering weather to do a copression test on all cylinders now?got me thinking :-( hope nothing is gonna be wrong

 

proper bottem end - ie steel pistons and rods

t3 turbo (although with your worry about lag this may not be a wise choise unless you have it built with roller bearings)

and better managment - maybe cosworth L6 or L8 or aftermarket if you can afford it

but this wont make the engine come on boost much earlier - maybe a lighter flywheel as this would help an engine rev faster so you could get on boost quicker, other than that you could get some heat protection on the turbo/manifold to help it come on boost quicker as well

how much have you got to spend?

Jonny S2 - i was reading something on turbos the other day in redline magazine and they said compression doesnt make much of a difference to lag and you could do lots of things before lifting the compression to get the turbo to come on boost faster

 

i wouldnt go t3 turbo if hes worried about lag, unless of course its got a roller bearing core

there are things you could do to reduce lag - get your manifold and turbo heat wrapped, maybe a lighter flywheel could help to im not sure...

i would look at uprating your managment - cosworth L6 or L8 or even P8 or full after market system - with a live mapping session to really get the best from it

steel rods and pistons

it all depends whats in the skyrocket, how much are you looking at spending?

make sure your car can handle the power though, good tyres, brakes suspension gearbox and clutch will be needed

if your getting a new gearbox you may as well get a diff too which sadly is more expense

EDIT: i wrote the first reply then the interent died and i didnt think it had posted so i wrote this one out, bloody computers

 

i know the bottom end needs improveing but while its still good il use it til it breaks,turbo is also quite newly re built so dont wanna change til its broken,maybe turn it up a touch though,in ur opinion would u say lagging a std manifold would be ok or wil it crack it?has any one used or got turbo wrap?seen sum on the bay,wil it cause me any problems?

 

tags are abit cruel boys...........

 

700 ish to spend,suspension is sorted although i could do with sum lower rear springs if any one has sum,its got cosworth front brakes on too so i think it should be ok to handle sum more power,defo gonna look into getting sum parts heat wrapped,any pics of wrapped manifolds and turbos would be a help too what prices roughly is better management gonna be,i think my aim is also gonna be to try reduce turbo spool up time

 

i just saw the tags they made me laugh,its a nice clean car 40k mile 1owner xr2i its not ready for scrap and burning yet!

 

no heat wrapping will be fine, you can get covers for the turbo to.

they have a double win factor in that they also stop heat getting to the airintake as mush so you get mpre power and less lag

 

thanks for ur help mate il hav a look on the bay when i get home tonight cos my phone nearly flat now cheers again mate

 

The other option is a 2.0 zvh will run about 230bhp on the rest of your spec

 

you need to get a bleed valve and open it right up till it blows up ha ha only jokeing paul
