Hello people, the head on my 1988 rsturbo is getting a little tapperty and its starting to do my tree in, as the car is only lightly modified with the usual, chip, exhaust, airfilter and front mount the next logical area is the head!

so what should i go for? a stage 1 2 or 3? i dont really get what the different stages are so any explination would be great, and what comes with the different stages

again goes for the cams there are loads on market and then there are all the different models within each brand but what would be best for the engine ive got?

i dont mind rebuilding it myself as ive got all the tools i just need to get all the different parts together any other advice would be great!

 

also be interested in this too . as my head is supposed to be a stage 2 and dont realy know what im looking for to see if it is .

 

stage 1 standard valves ported

stage 2 bigger inlet valves standard exhaust valves ported

stage 3 bigger inlet valves and bigger exhaust valves ported


NMS do good ported heads but there is a long waiting list > http://www.norrismotorsport.co.uk/index2.html

Also pumaracing is very good but yet again a long wait > http://www.pumaracing.co.uk/

Jamsport also do good heads and they usually have them in stock > http://www.jam-sport.co.uk/

 

so if i chucked on a stage 3 head id obviously be drawing in more air and getting rid of it quicker but would that then mean id need to uprate the turbo as well?

 

no you can use it with the standard turbo you will have more power at the same boost pressure from the improved VE

 

Nick from PF was running Jamsport head piper 285t2 cam pro alloy front mount and standard turbo 18 psi 250 bhp iirc

 

quality, right lets find some prices lol!
obviously it will need mapping as well wont it, anything else i should uprate/update whilst im doing that?

 

i think NMS are about Ł500

Pumaracing Ł650

Jamsport about Ł400

not much more you can do yourself next after the head and cam would be a bigger turbo something like a stage 2 hybrid 5th injector or a change to Efi management

 

Stage 1/2/3 different from different people, as thier view is different on what the stages are.
You could try DARREN at DAMICO, 01953 717784.
He is awsome with heads as that is all he has ever done, has flow rigs, engine dyno's etc , so unlike some his heads are not guesses.
tabetha

 

im currently collecting efi parts as i go, slowly and cheaply!

 

i have a ported head if any 1 want it Ł75ono






will suply with
valves
spings
retainers
new valve stem oil seals

 

if anyone wants there head porting/ polishing i can do it for u, i do them on a daily basis for the company i work for, i`ll do it for Ł100 all in, can do other head work aswell, just pm me

 

you have a pm mate!

 

fpmsl at diy ported heads

 

if you had standard cam 7psi and a stage 1 head what kind of power increase would you expect obviously there would be less lag etc 5bhp???? i am still running origional cam at 120k should imagine its pretty worn so may replace the head.

cheers

 

thanks for all the replys people, looking at so many different options now lol!

EFI wise ive allready got the inlet, injectors and throttlebody. along with the map sensor and coilpack and ht leads.

got a price from cylinder head developments which seems quite reasonable and ive allways heard great things about the owner.

need to look at cams now, any recomendations, kent, piper, newman?

 

piper bp 285 t2 in mine

good stuff

 

m8 theres nothing diy about me porting a head, i work for a company called autocraft, basically speciallising in performance cylinder heads, about as far from diy as u can get

 

are you wantin this cylinder head?

 

wot sort of stage could u do this too mate.

 

wot sort of stage could you do this to mate would you deffo feel a difference???
