This is slightly off thread.
I'm thinking about installing a PE turbo (via Prolex) mainly because of simplicity and cost, and as a starting point for other things.
I've read the threads on here and SP.
I'm a bit worried that I should install something else at the same time, ie 'wideband' at least, which I don't understand (as in 'never heard of' - it's just a downside of age s:(

s:( )
Explanation appreciated

I would recommend some sort of electronic mapping control rather than relying on the PE's fuel pressure tweak and disconnection of the knock sensor - it'll give you a safer setup.... and if you get mapped properly, then arguably you won't need the luxury of a wideband (which accurately tells you what your air:fuel ratio - AFR - is).

Obvious choice for the price would be the EManage Blue, or EManage Ultimate for its advanced logging and "safe self-tune" (with the addition of wideband) options.

Split from Aarons top secret thread as i think this deserves a thread of its own without drifting Aarons too much

MOD hat off now - It's always recommended to use a piggy back or replacement ecu when you're forcing air into an engine as opposed to normally aspirated. Above all things it gives you a safer tune which will help prevent any nasty engine damage. The PE and TTET can be installed without these but their alternatives are pretty rudimentary (heath robinson?). IMHO they can both be enhanced with either E-Manage Blue, Ultimate, or a full blown replacement ECU.

They both work very well and obviously the PE is a great price. But the most you're safely going to get out of either is going to be what, 200 to 210bhp? Which to me is plenty power. s:wink: :wink: s:wink:

The Silverstone Performance additions claim up to 240bhp, but at what risk. (Hint) s:? :? s:?

I'd speak to Davy (VVTi) as he's going for a PE via Prolex in the near future. From what he's said Dave from Prolex has been very helpful in suggesting additional parts which are useful to accompany the basic kit.

When we did my install a couple of weeks ago I already had engine management (Emanage blue) but the tuners (Hypersports) suggested larger than stock injectors as necessary as mine were maxxed out at high revs. My shopping list for the future consists of New exhaust (just cos mine was cracked) Bigger injectors, intercooler, wideband 02 sensor + innovate, and anything else Ste tells me to buy!

Other stuff you'll probably need or want to get may include gauges, a blow off valve, boost controller (mechanical or electronic), additional bracing for the new manifold, clutch and flywheel. You'll probably want to factor in more regular oil changes so decent oil and filters, super unleaded fuel as well. It all adds up, not that I'm trying to put you off, cos when you put your foot down it's most definitely worth it.

Am I over simplifying here or could you not just up the fuel pressure? If you are just in tune on max flow, a relatively small increase in pressure could see you OK.

The other suggestion from Chris at Hypersports was to put in a fuel pressure regulator, but Injectors seems a better option if I want to go for more power in the future.

Wabbitkilla · September 23, 2007, 06:56

A fuel pressure regulator does come with the PE kit as standard but was missing from Phils (2nd user) kit. So yes this would 'help' but it in itself isn't the complete solution, add engine management and bigger injectors and it's a better proposition.
Don't get me wrong, it'll have you flying nicely, but the add ons provide refinement and peace of mind.

The PE is built to a competitive price, but you can easily improve it, hence Dave at Prolex adding the intercooling.

The urge you get in reaction to your right foot seems well worth it.

aaronjb · September 23, 2007, 09:58

I have ranted elsewhere on why the RRFPR is a good idea in any case, so I won't do it all again here s;)

s;)

But suffice to say I still think that if you're going to really do things properly (regardless of injector size), you ought to have a RRFPR in there.. of course on our cars it's a royal pain in the backside as the current FPR is inside the fuel tank s:(

s:(

But there does come a point where it would be essential - if you were ever pushing 40psi of boost, no fuel would come out of your injectors at all - whatever size they were s;)

As evileye has said, I am in the precess of getting bits and pieces together for a PE conversion, I am going for the innovate wideband kit... 550cc injectors, emanage ultimate, intercooler, flywheel, clutch, boost controller, dump valve, new exhaust with 3" pipework.. I will be putting in 5 guages too..... boost, oil temp, oil pressure, EGT, and the AFR that comes with the wideband kit.

As for the injectors... Dave was speaking to someone from Greece (i think) when we were at knockhill, the chap had previous experience of the PE kit and told Dave that upgraded injectors were needed to get the best out of the kit, this was something neither me or Dave thought was going to be necessary... but as evileye has said.. his injectors have maxed out.

loadswine · September 23, 2007, 15:32

You never know, I might have a few bits that might help with your collection, I may not be able to sell my PE kit as a complete unit, though it has pretty much all you could require, so might end up splitting it and complete several people's collections of bits.

I have to say that I am a complete fan of the PE conversion and its inherent driveability, Its just that the opportunity of having Europe's first V6 came up and I couldn't not do it! s:P

s:P
If I can be of any assistance at all with any PE projects, I am always happy to answer any questions that I am able or share pics of my install (as was!)
( I am not as knowledgable as some of the guys on here, but have run one for a while and that may help)

So, what I conclude from this at the moment is that I should get say 200bhp from just fitting the turbo (must get good torque increases also) but in a fairly unrefined fashion. So it may well be a good starting point?
Thanks for the response

I doubt you'll actually make 200 bhp. I made just under that and we weren't expecting those numbers, and that was with tuning with emanage. The numbers also improved after the fitting of the boost controller. I don't know if I'd have wanted to have done the install without the tune as well. It might be an idea to factor in the cost of engine management and a tune just for the peace of mind that nothing is going to go wrong.
