turbo conversion on mk1 vts

16th July 2011, 00:38

hi guys,
i will be doing a turbo conversion on my vts end of the year and would like to know a few things.
i know about some things to buy just not all of it . my list so far:

low compression pistons
16x valves
intercooler
dump valve
port and polished head (my choice)

what mm headgasket should i use?
which turbo to buy?
what are the best cams to use?

and could other people tell me what im missing from my list ?

cheers

Danny

What will the car be used for? daily driving?

Realistically what is your budget?

What power are you wanting to achieve? (i only ask this as youve chosen forged internals which suggests it wont be a very low boost setup?)

16th July 2011, 00:51

car will be used for shows and a bit of daily driving
budget....not got one, what ever it will cost
power....as most as possible

16th July 2011, 00:57

Speak to Blackie_2k5..no doubt he'll find this anyway..but he seems to know his stuff when it comes to his turbos

here we go

Right realistically if you havent got a budget and want as much power as possible

forged rods and pistons £1000
Large turbo say a gt30 £800
big valve and worked head £750 -£1000
Manifold and downpipe anywhere between £500 and £1000 your choice
injectors £400
bigger brakes £200-£400
larger bore exhaust £200
be gearbox and shafts etc to take the power £1000

carry on?? you cant just say no budget and as much power as you can.... you've got to stop somewhere

16th July 2011, 01:09

i'll stop when i get bored lol.

which injectors?
whats a be gearbox?

is there anything else to add on the list

16th July 2011, 01:15

well if you fit what a gt30 as stated above and run big boost to get 'as much power as possible' then you'll need 630cc's or something similar.....

a be gearbox is a larger gearbox, found in the 1.6 8v petrol which has larger diameter driveshafts which helps with the strain put on the drivetrain under boost...

seriously though if you have no budget which i doubt is true you could spend £10k easily

16th July 2011, 01:24

ideally i dont want to spend more than 10k on the engine . as i have other plans for the interior etc.

cheers for your help though mate.

anyone else think what else i would need ?

16th July 2011, 01:27

speaking from experience, i'd NEVER EVER spend 10k on a saxo again, let alone just the engine

but if thats what you want good luck

16th July 2011, 01:50

what would you suggest being a good enough budget for a turbo conversion then?

the be gearbox, what car is it from? its bringing loads of different ones up on ebay

16th July 2011, 09:42

once you have you're 10 grand engine how are you planning on keeping that power on the black stuff? imo I would get suspension,brakes and tyres sorted before a 10k boosted engine

16th July 2011, 10:26

take the car to Atspeed

16th July 2011, 10:37

i suggest u make a power average you want to achive, 10k on a saxo engine... rather you than me..

but u gotta realise aswell, once you built this 10k engine, your probs going to at the point where you have to much power to keep the rubber sticking to the road without speding another few k on suspension, wheels tyres etc.. and if your looking for major power i suggest some stregnthening around the car..

16th July 2011, 13:10

hmmm i didnt think about making it stick to the road, think i may have to change my ideas slightly lol.

with a basic turbo setup, how much would i be looking at to see around 250 - 300 bhp ?

what are the best tyres to use, coilovers and also brakes? iv heard 206gti brakes are good, will these be enough?

cheers

your best speaking to ATspeed mate, there the best people to talk to, they can give u up to date quotes, remember u need mapping and setting up costs ontop of parts costs..

16th July 2011, 15:42

Add to costs - fitting & mapping!

16th July 2011, 15:53

Have you searched at all?
If it's a road car just take it to atspeed and get them to do a stage 1 conversion.PLENTY fast enough for the road.trust me I know

what bhp will it run on a stage1?

iv just been looking on atspeed website and worked everything out, its gunna cost in the region of 8k+ and im still missing loads off the list

think i need to sit down and seriously think , do i really want to spend this amount of money on an engine. i just wanted something which is fun to drive

16th July 2011, 16:17

first thing is first mate, do you have any mechanical knowledge? are you competant with your hands/tools?

the above so much isnt a necessity as long as your willing to learn and take your time, if this may be a prob for you, then you have to start thinking about getting someone else totake on the project for you, as we all know woring with cars/tool etc isnt, for everyone,

if you can, then i suggest you undertake the majority of the work yourself, with alot of reading up and seeking help you can more then achieve yours goals, i did, lots of others on here have

as realistically getting it all done for you, nigh on doubles if not more in alot cases the cost of the project?

16th July 2011, 18:30

your talking a 10k setup easy my friends 106 gti turbo cost 15k to build and thats 300bhp

can be done for less

16th July 2011, 20:28

depends on the standard you want it to be done at?

16th July 2011, 21:18

not really, its pretty easy to get a forged 16v to 300bhp for WELL under 15k

16th July 2011, 21:48

he's probably talking about Ross Ds gti Andy if thats the case can't compare as ross has gone best of what he can get, Just priced Jonesey9 a decent package DP kit etc etc for 3.5k within that included clutch, bigger injectors and all the other usual things

yes i have mechanical knowledge, good with tools etc . also willing to learn more. iv pretty much taught myself about engines etc with old cars and watching other people work on theirs etc etc.

15k to get to 300bhp.

how much would it cost me for a stage1 conversion and whats the output roughly? im going to concentrate more on my interior side of things , so a stage1 will do for me.

17th July 2011, 11:22

been looking on threads made in the past on here (should have done this in 1st place lol) and iv a few questions:

do i have to use a BE gearbox if im only running a stage1 turbo conversion? i dont want my s box to start shredding itself.

my car has ABS , the BE driveshafts etc are non ABS, does this matter?

it says when using a BE box, the powersteering will have to be re-located.....where to?

lastly, which cars use the BE box?
its bringing up a few different ones on ebay, does it have to be 8v or 16v.

cheers

17th July 2011, 11:32

I am sure atspeed supply you with everything you need for the be conversion, not cheap but if you are spending 10k on the engine you might as well go for it

17th July 2011, 13:08

change of plan, not spending 10k on it now, .
i just need to know the answers to my above questions then im happy

17th July 2011, 13:18

power steering pump can be moved anywhere mate, if keeping it in the bay your limited with a turbo conversion, but you can get new hoses made for next to nothing at a hose/hydraulic company, relocate it to you boot with the battery, one on either side will even the weight out.... if going stripped out you can put one behind either seat

if your doing all the work yourself you'll save a FORTUNE, the stage one kit atspeed supply can probs bebought cheaper from dp direct, and sourcing the extras on ebay etc, then fit youself and the trailer to atspeed/gmc/local... or wherever you choose for ecu/mapping, or if buying a pred andy will come to you

on gearbox it totally depends on the boost you want to run with the sta one kit, lots of ppl just buy a diff for the MA box and run 250bhp, theres a couple for sale for >700 in the sale section, this will give you and LSD and uprate the box a bit, BUT BE with diff would be better, or just BE without diff... but if you can afford one its always a sound investment tbh

if wanting to go the BE route diy style, the martin "tweeqd" done a pretty usefull info guide on here, if you can get a local engineer to do the machining and welding... it should work out at a very reasonable price tbh....im looking into this for my next project

17th July 2011, 13:35

cheers mate, will have a look for that guide, see if i can find it lol .

24th July 2011, 09:50

hi i am thinking of doing a little project with my saxo but can make up my mind as yet what sort of boost does it run and are you running any sort of standalone ecu ?
