bernmc Posted August 1, 2006 Share Posted August 1, 2006 dirty boys. Alters the stroke of the engine (ie how much up-down distance the pistons travel) to increase cubic capacity. Quote Link to comment Share on other sites More sharing options...

Baptist Posted August 1, 2006 Share Posted August 1, 2006 The cost of doing stroker + Forced induction would be unbelievably high to say the least. Its not really necessary if you are doing forced induction. Quote Link to comment Share on other sites More sharing options...
mugwump Posted August 1, 2006 Share Posted August 1, 2006 Teach me oh wise one..... My concern is that the FI route puts extra strain on the engine and there is lots of (possibly hearsay) info floating about that the VQ has weak pistons, and open deck, weak con rods etc. This makes me very nervous about going FI. BUT I WANT IT! So my thoughts were, if the engine is bulletproof to start with then it is more capable of taking the extra FI load???? Finding it difficult to find any info about peoples long term experience of FI, is the engine reliable? What are the issues? I have read the "tuning 101" guide on here that says FI needs frequent attention to keep the engine in tune but what does that mean? Trips to the dyno every 4500 miles? or every 500?

I have read the "tuning 101" guide on here that says FI needs frequent attention to keep the engine in tune but what does that mean? Trips to the dyno every 4500 miles? or every 500? Some of my concerns there too. Basic is that NA engines typically run higher compression ratios - 10+:1 whereas FI tend to be around 8:1. Bolt a big blower on to your Z, and it's a lot of air/fuel mix being pumped into that tiny space. There are mutterings about the pistons used in the std engine being weak around the ring area etc etc. As you say, it's quite difficult to get straight answers... A stroker kit will set you back $5000 - without fitting and machining... then add your turbo... big dollars, but I suspect the only way to do it reliably. Depends on how much boost you want to run, and how long you plan to keep the car.... Quote Link to comment Share on other sites More sharing options...
Baptist Posted August 1, 2006 Share Posted August 1, 2006 If you are intent on doing FI, then you can do it without doing the internals. Of course, if you fit an uprated bottom end (pistons, conrods etc) then you will have a much more reliable car. Alot of people run FI without going to this extra expense, with no problems at all. As long as you keep to around the magic 400bhp mark, providing you are correctly tuned, you should be ok. As with any modified engine, their are inherent risks, and you cannot expect factory reliability (whatever that is, as standard engines can break as well!) My last car ran the Vortech for about 11k miles with no problems, and my current has done 13.5k out of 15k on the APS TT kit @410 bhp, no problems at all. Its all about how much you want to spend. I dont know of anyone that has successfully done the stroker and the TT conversion. Im sure it has been done, but you come across alsorts of issues if you increase the capacity, as the turbo's in these kits are matched to the cars current displacement. To be honest, if you are thinking of doing a high power FI application, then 3.5 litres is more than enough for you too run higher boost that would give you extremely high power. The problem with the Zed is, that its only 2WD, so you need to ask, what is actually practical for traction. All good and well being able to boast about X amount of power, but if you cant use it, then its a waste of money. I've chosen to stay with standard displacement on mine, you will get the same effect with running higher boost @ lower compression. Hope this is of some help.

mugwump Posted August 1, 2006 Share Posted August 1, 2006 Hi Baptist, yes that is a great help, I dont really want more than the magic 400bhp but I use the car as a daily driver so I dont want to compromise the reliability if possible. Will a boost controller allow for the car to run at reduced boost 90% of the time and only at 400 when I wish to "turn the wick up" or would such a setup mean that the fuelling etc would be way out of whack in one or the other (on/off boost?)? Should I consider a Nitrous system instead as that would provide the boost on demand? Am I just a power obsessed deranged petrolhead? Sorry for the dumb@ss questions, I am happy with how a turbo works and what a boost controller does but have not actually done much tuning of cars. So I'm learning all the time....

No such thing as a daft question. Of course, the car would be more reliable doing the bottom end for that power, but you have to weigh up cost on doing it. Its really not cheap to do. At 400bhp, I would stay on standard internals. (purely for prohibitive cost reasons) Will a boost controller allow for the car to run at reduced boost 90% of the time and only at 400 when I wish to "turn the wick up" or would such a setup mean that the fuelling etc would be way out of whack in one or the other (on/off boost?)? You'd need a ECU with a selectable map to do that. Would cost alot more to do that. In all honesty, if you dont want the power, just dont put your foot down as far. Should I consider a Nitrous system instead as that would provide the boost on demand? Nitrous is only good for drag racing really, for the cost of it, you get very little time out of bottle. Couple of minutes at best. Insurance companies hate it, as well. Am I just a power obsessed deranged petrolhead? Yes, and I am just the same, as are most on this board! Sorry for the dumb@ss questions, I am happy with how a turbo works and what a boost controller does but have not actually done much tuning of cars. So I'm learning all the time... No probs, its all a learning curve, especially with this car. Any more questions, dont be shy. Jon Quote Link to comment Share on other sites More sharing options...
mugwump Posted August 1, 2006 Share Posted August 1, 2006 In all honesty, if you dont want the power, just dont put your foot down as far. That made me laugh! How would I ever resist! Even on stock I slow down and accelerate on dual carriageways for no better reason than to listen to it! Thanks for your advice though, its great to hear from people that have been here and done it.
