16v turbo setup

8th October 2008, 13:42

ok guy, i am curently in the process of buying a turbo setup for my vts, got a few questions if a yone could help me with them, cheers in advance.

1. what way would a turbo setup work with catcam 708's?? do they need to be timed defferent or just keep them the same as they have been??
2. what kind of management do you reccomend?? i was thinking od the D-P engineering piggyback one, mainly because it says its totally capable and i dont really wana spend mega muni on full standalone.
3. what abut compression ratios, im not going to use pistons for the mean time, is decompression plate suitable or what other optins are there?
4. what sort of boos would i be able to run safely without forging??
5. And finially what about fuelling?? what size of injectors do i need?? do i need bigger pressure regulators, diff pump etc...??

thanks again any help appreciated

Theres a whole engine for sale matey in the for sale section but think he wants a few grand lol..... that would be worth buying to save the hassle of building one yourself

Think theres a few posts on this anyhoo..................you done a search fella

These are my opinions on your questions:

1. I dont think it would be a major issue if you run standalone management
2. Standalone management is a must for turbo conversions in my opinion. Predator ECU is completely stand alone and is plug and play too (if you have the single plug ECU?). Cost is around £600 I think (sure Andy or Ross can confirm), although there is a group buy at the moment which brings the price down to £500 I think.
3. Compression ratios I am going to be running 9.0:1 in mine which is sufficient and most popular, but I have seen one person running 8.5:1. Not sure how you could measure this using a decompression plate / double headgasket, but thats not something I would advise anyway. Do it properly with forged pistons and rods the first time round is my opinion.
4. Boost on standard internals not much, hardly worth doing in my opinion.
5. I think I am correct in saying, there is no point having larger injectors unless you are running stand alone. I think the standard pump will be suffice for 90% of conversions to be honest. The other option is to run a 5th injector but thats the cheap option if you cant get more fuel in by any other means (i.e mapping it on a standalone).

708s will not benefit a boost setup.there is too much overlap. Just use standards or boost cams.

I know nothing about the dp management but you could look at running an mf2 with a 5th injector.that's a cost friendly option.

Standard pistons will be ok if you don't go mad on the boost.

I know sophia bush wrote in my for sale thread about having everything else you need,well he does,even the elbow to hold the 5th injector for the MF2. The only thing you would need to buy would be the mf2 itself.

Yeah our Predator ECU will sort the mapping side 100% and as said, it's £500 fitted and mapped on a group buy discount at present

708's again, as said not good for a turbo unit. On stock cams you can take it out to 300+bhp, exactly which gear do you want to still be wheel-spinning?? hehehe!!

Actually, lcheater has covered the lot really - he is Mr Turbo right now, it's a no-holds-barred Turbo conversion! Top drawer parts. Would be worth following his progress thread

All the best

Yeah I personally wouldnt want to run much more than that tbh

if you have a good intercooler setup and it is mapped right 10psi has been seen and not had any problems previously
