Time to start on turbo conversion

24th July 2009, 17:44

Yes as the title says, it says the word "turbo" so no mocking, serious responses only please.

Been speaking to a lot of people and dp engineering in the planning on doing my turbo conversion.

My target is 180bhp which yes I'm quite aware is easily to hit with n/a but in the end I've chosen to go boosted route.

Got a near complete list of what I will be ordering in the next few weeks but I do have one slight question (and most likely plenty more on the way through)

I've been looking at using a turbo from either Fiesta RST T2 or Escort RST T3. Both turbos are water cooled. Would it be best to run this of the current cooling system used on the Saxo VTS or would I need to run a separate water system? As far as I was only aware there was only the connections of:

Air In
Air Out
Exhaust In
Exhaust Out
Oil In
Oil Out

Can someone elaborate on this for me before I go ahead and order my turbo. Decomp plate is already on it's way

and will hopefully be seeing Luthor1 and his team for the Predator ECU at a later point.

Further to this If I am wrong please can someone post some pics up including the pics.

Cheers

I dont claim to know exactly what is required but if the turbo has/requires water cooling then it should be piped up accordingly, the existing water cooling system in a VTS is usually up to the task of cooling the turbo also, would be worth considering a cooler thermostat???

Like youself I am looking to turbo my VTS also so any advise/specifications of actual turbo's would be appreciated.

Thanks.

I've already dropped my thermostat to 80oC at the same time as my missus one, made a serious difference as it was on a 89oC one

Nice one, do you have the part number of this thermostat, been trying to source one for a while now.

Which turbo you decided upon? T2 up bigger..

only going for a T2/T25 been speaking to some and they say that the T3 can quite reduce the clearance between the radiator and the turbo hence forth increasing heat on the radiator = not good.

24th July 2009, 19:19

I see, T2/T25 sounds like a popular turbo for tight engine bays like the VTS

You cant go wrong with the Predator m8e, I currently own one and it was one of my better buys as it can now be used on my turbo setup, what will you be doing in regards to injectors? 300cc or bigger?

What are you doing in regards to manifold & downpipe?

Remember with turbos cooling is your friend deffo upgrade the rad puts less heat on the turbo witch will fail oneday what boost are you looking to be running ? i do prefer the T25 tbh

Have you thought about fueliing mate??

%th injector and controller unit

For fueling to reach 180bhp, according to DP it can be done easily by increasing the Fuel Pressure Regulator to a 4.0 Bar (just got my one for £23!

) Manifolds I've been looking at the CAST ones that http://hiflowheads.co.uk can offer or going to adapt my current one, checked with my mechanic who has done one for a corsa tubby conversion before.

200sx are a popular choice for manifolds aint they??

A year or two ago i did look into building a big power saxo i purchased a few parts but then sold it for my current car

Im a lil sore when it comes to info but i shall try and help haha

24th July 2009, 19:57

Dont get a cast manni cos there shit

As for the fueling your best off with bigger injectors an fuel pump incase you want more bhp in the future...

Im turboing my vts an im doing nothing on the cheep, as it will cost you more money in the future...

24th July 2009, 19:58

shorty_phil - Yea the S13 one's i believe but they need a bit of stretching to align the valves

3cott - thanks for the info on the cast mani, for the mean time I'm only doing a setup to meet my target. After speaking with a lot of people, pushing over the 200 mark your asking for tons more trouble, bearing in mind its only a 1.6 engine

Spill the beans pal, where you get the 4bar fpr & thermostat

Local parts shop, its a bosch FPR

Can get the FPR from DP http://www.dp-engineering.nl/EN/prod...ch_ifpr40b.php

I spoke to john at GMC an he sed with pistons (low comp) you good for 250 bhp at the fly (witch is my target) any more than that will kill the gearbox...

If you keep the temps down an dont raise the rev limit any more than it should be (7200) you should ok...

24th July 2009, 20:18

3cott, you referring to std pistons or something like the PEC Turbo pistons?

24th July 2009, 20:21

If you could provide a part no of the bosch 4bar from the local part place as the one off dp engineering is quite steep lol

Wossner, forge ect ect...

manc - Option 2 for you, fleebay! http://cgi.ebay.co.uk/306-GTI6-4-BAR...3%3A1|294%3A50

3cott - thought so

Cheers pal

I've got a spare vts inlet manifold which I'm going to strip and remove the FPR then take it to my local part place (GSF) and ensure its 4bar

, I'v heard that 1bar equals an extra 10% flow so your heading in the right direction, myself I'm hoping to get 4bar fpr & clio172 283cc injectors which shuld suffice for 190/200bhp which I'm hunting, very similiar to you

You dont need a fpr, all you need is a uprated fuel pump an injectors...

24th July 2009, 23:02

for cooling get a custom cooper rad made to your size and spec ! nice little touch they are..

25th July 2009, 12:19

GRS motorsport is a company to speak to if you want to go down that route, they my not be the of cheapest, but the quality on their work is bloody great.

25th July 2009, 21:16

there a company on ebay offering to make them, also intercoolers, ppl from here have bought them although im not sure who? might be worth looking into could get a deal on both, prices sounded good from what i rememba

26th July 2009, 19:12

Well after today looks like I'm going T3, as I've managed to acquire one with a AR .48 housing which is a smaller housing than the typical ones used on a 2WD Cossy so for size wise it will fit. It is water cooled so will have to attach that the the current cooling setup which is not a problem, just got to get some more T-Pieces with right fitments,

Now another question, does anyone know the thread sizes used for the oil pressure sender for when fitting the oil feed? from what I found so far it "should" be 1/8 NPT, can anyone confirm this?
