Parts And Costs In Fitting A Turbo Engine.

[danny56712 1]

The 8v turbo engine lads im just wondering does everything fit as standard, turbo, exhaust etc. What intercooler do you need and basically what are the costs and parts involved in hitting around 200bhps with one?

[chrisj21 2]

Plenty of topics on this, have a look in the works and projects sections and use the search facility.

[jonnyturbo 3]

as already said theres many topics do a search using turbo or XU10J2TE which is the engine code for the 2.0 8v turbo, afaik everything fits bar the gearbox and intercooler/pipes. to run a safe 200bhp you will be spending some £££

[Tom Fenton 1,542]

I disagree. Standard 2.0T engine with a mappable ECU and decent intercooler and you are there, a second hand ECU is available for something like £350 now.

[jonnyturbo 3]

so a few £££ then?

[Tom Fenton 1,542]

When you compare to the cost of getting 200bhp from a Mi or GTi6 engine, not really.

[jonnyturbo 3]

you can gain about 190ish from just turning the boost up but as you well know its not really good for the turbo or engine i guess but for a reliable 200bhp you want to do it properly as tom said mappable ecu, pm sound of silence as he got some good gains from the 8v turbo but cant remember what he did lol

[danpug 1]

His results were on a std engine with just the boost upped.

whose?

[danpug 1]

Its actually rapiecossie's i was talking about but soundsofsilence did have a turbo engine with a few other bits done to it, i think the details are in his 16v turbo project thread.

[sounds of silence 2]

we have done loads of these conversions should be able to see around 200bhp with a good exhaust system , good intercooler and decent intercooler pipe work followed by a boost increase also very reliable seen well over 200bhp with a good choice of mods tho .

 

alot of people slate this style of conversion but i have yet to see any we have done to be unreliable and for the money i would find it hard to see a car much faster

Thanks for all info guys and are any of the ngines better than others eg dished pistons etc

afaik the rgx from the 406 is the best one (dished pistons). well it had slightly higher bhp as std not sure what thedifference is when decatted and a boost c ontroller fitted.

If you use a late engine, i would look at engine management being an essential part of an upgrade. My late Xantia throws a code at anything, from boost rising too fast on part throttle, or getting even slightly close to the 1 Bar cut off. The earlier ones are not so bad, but its a stumbling block to gaining more power especially if you go for a bigger turbo. They will run 12psi all day long but efficient intercooling is a must, as its a small turbo and creates a lot of heat. I doubt you will see a genuine, consistent 200bhp whilst running the original turbo and on the original ECU.

[sounds of silence 2]

shouldnt throw management faults if everything is working properly

 

not hard to get a bigger turbo either we had one purpose made for the std manifold and coupled with a cam and management saw over 230bhp

 

correct with the intercooler tho a decent one is a must to keep air temps down

 

had one of ours make 197bhp @11psi

 

if everything is working well together you should see a genuine 200bhp

Everything is working as it should, its been on the Lexia loads of times to make sure.

 

Its because the boost control is no longer done by the ECU. EMS light on for a few seconds once started indicating a code has been logged and ECU back to default not adaptive. . Every time it says its to do with the boost control solenoid.

 

 

I had the gain set up so high that it was quicker on part throttle than full! Now sorted. I do run a bigger turbo and it makes a difference, but as said, if you have really late management it wont work as well as the earlier version, possibly to do with the tighter emission regulations.

I must admit I was surprised at what I got away with when I put a boost controller on my '94 XM compared to my '96 Activa. I assumed it was because the XM was an auto and never really revved through the range properly but you may be onto something.

Mines an S2, and i'm pretty certain it uses a later version of the Mp3.2 Bosch EMS even compared to the S1 Activa.

[sounds of silence 2]

worked with both styles of engines and must admin never noticed any difference to be honest

 

do you still have the std boost controller plugged into the management aswell as a form of manual boost control ?

Yes the multiplug is connected but the hoses are not, obviously! As soon as the plug is removed, you get a permanant EMS on, so it has to stay.

 

I had a manual boost controller bypassing the BMV (boost modulating valve) which worked quite well really, but went to the electronic boost control to give me various settings and flexibility.

The Gizzmo is really good for the money.

 

I'm not sure how late the engines are that you worked with. Mine is a 2000, S2 using plastic inlet manifold, different throttle body etc. This change happened late 97.

lads thanks for all the responses but seems be good few issues with these engines in my opinion not big problems but too big for me

[sounds of silence 2]

ye never worked on a 2000 one mate never even seen one of the turbo engines with plastic inlets etc to be honest i was referring to the older xm (94) engine and 406 (97) engine

[rapidcossie 0]

IMO the turbo engine is a better choice due to the torque the engine produces making in gear acceleration much faster.

 

 

Mines runs 14 psi and made 180 bhp with a bad missfire due to a badly cracked coil pack so Id imagine it would be close to 200 now that its healthy again. edited to say my engine runs a full 3inch exhaust and evo6 intercooler.

 

I was also worried about reliablity but I have now done two track days with no problems at all, the engine uses no oil or water although the turbo does scream a bit due to the over pseeding I think.

 

I wouldnt go back to a gti6 engine now if you paid me lol

The engines are solid as a rock tbh. Mine burns no oil and is quiet as a mouse. You just have to remember, it was designed to be a torquey lump so if your expecting a screamer it will not be for you. Everything was designed to work in harmony and provide a responsive, smooth engine, it does this very well as standard. But will it suit what you want from your car? Up to you to decide.
