i have a sapp 4*4, with green, map, chip, kn, 3' exhaust line and t34 with .63 housing, and in few days a rs500 cooler
i suppose that i have between 300-330 bhp

i would like to know what mods i need to do to obtain 350-400 bhp with low budget

 

Based on that spec.

A remap should see you over 350

 

if your on a low budget then don't stress your engine to much, or it may well stress your budget!

 

low comp pistons, WRC gasket, cams, greys/ light blues, little bit of head work + more boost should see 400bhp

 

next year, i will rebuild an engine with ported head

but, i can't have more than 350 with high comp and std cams?

 

Not very likey i'm afriad....

Maybe using higher RON fuel but not on the 98/99 RON stuff which is sold here.

**Edit noticed your are french** what RON fuel is sold in France?

 

as chip says a propa mapping session should see your car make good power ,might need to up to blues or greys to make the most of your spec if having a proper map done

 

hi, we have 95 for standard cars, and 98 for olders cars

i put 98 eveytime on my cossie

 

i am agree for the remap, but i need to do all mods before the remap, it s the reason of my question, i want to buy and fit all in few month, and planned a travel in your beautiful country

 

Greys or bigger. Closed loop. Live map. 33peak 28 held.

Fast, reliable and economical Car.

 

Would he not need a new headgasket before he got to the end of your road stu? And maybe uprated fuel pump? Not havin a go just interested cause i'm thinking of gettin mine done with you

 

yes, i am agree with you

In fact, i have standard headgasket with strong and long stud, but i am not sure that it's the best solution

 

You have your block long studded but use a standard headgasket?

 

Yes, because i had planned to rebuild my engine next year, so, i didn't want to deposit the head

Somebody told me that is not a problem if the headgasket is in good condition

 

ok, and what mods when i will rebuild the engine ??
low comp piston or not ?
cams ?
breather system ?
Swirl pot ?

regards

 

depends where in that 350-400bhp range you are aiming.

For 350, you dont even need different injectors.

 

you know, we want always more power

so, the best for me would be between 350-400, so a middle 370 will be nice

 

carwise uk r building my engine at the mo.1000cc injector's ,t4, new chip,lowcomp little bit of head work.mine should see 380, 390 bhp.
can't wait.
bring on the drag strip next year
i just have to say they r a sound set off lad's.cheer's all at carwise

 

sounds like a VERY conservative estimate on power?

is that at the wheels or something?

 

don't know. neil said it will b around the 380,390 mark.
i'll let everyone know when i get it rolled.

 

im not very good with cars lol but i think u need a swirl pot i dunno about anything else.......(reason i say this is cos i read in a magazine about a sapp 4x4 with 400bhp and i remember that bit lol!)

i also remember the person had an RS500 intercooler just like your getting and 0.63 exhaust housing, on i think a 2wd manifold.
wow ive impressed myself on what i remembered there is a bit more but i dont think it would be relevant to put down.

i was probably no help but still

 

chip if that's at the wheel what would it b at the fly.
just out off interest.
cheers

 

Getting up into the 500bhp ballpark mate.

Cant see why else you would need 1000cc injectors, and the T4 (depending on which variant it is) is good for 500bhp+ too.

 

fook me.cheer's mate

 

do you need a T4 to get 400/500 bhp to handle the pressure or something? sorry for the question i just wondered

 

Its all about airflow.

To make 500bhp the engine needs to consume a lot of air, a smaller turbo wont flow enough air into the engine to allow it to do this.

If you were here, and naked, i could explain it a lot better TBH, why not pop round?

 

lol i think thats a good enough explanation x

 

ok, i think that i know what i want for the future

i will put some grey, so with my big t34, it will be fine.

Now, i need some advice about the engine:

- i will put a breathing system an a swirl pot
- i will rebuild my engine with ported head

but,
-
what headgasket i need to buy a group A or a multi layer ????
what piston i need to buy low comp or standard ????
i had read that i can keep my standard cam

i think that i will put closed loop and at the end make a live mapping

SO, do you think that i forget something

Thanks for your help

a picture of my actual motor

 

For that sort of power i'd keep the standard comp ratio

 

ok, you have the same spec that i want no ?

 

Yes its a very good spec that doesn't need the engine pulling apart and it drives nice too, its about 370-380bhp the boost peaks about 33psi and holds 28

 

and its very good on petrol too

 

B11GNS why have you had all that work done and fitted a diesel turbo.

Please change sig to a T34 not T35

 

Looks like its time for another 'is it called a 34 or a 35' discussion!

 

I always thought a T34 was an escort T35 with a .48 exhaust housing on and the T35 had the .63

 

Please see post by your chosen tuner on thread titled 'FAO turbo know it alls - UPDATED - its not magnetic'



Just joking ppl before you all get the hump.

 

 

my turbo, is a big t34

.63 housing and 76 inlet, not 70

and for the gasket, any ideaa

 

Mines got a grp A one but only because thats what was in there already, its probably ok but if i had to change one i'd go for a multi layer one

 

ok thanks

But there a big price difference, so, if the group A gasket is enough for my spec, i think that i will buy it
