rampage Posted August 5, 2008 Author Report Share Posted August 5, 2008 This thread might answer your question. Lots of good info. http://www.starquestclub.com/forum/index.p...0range&st=0 Thanks for the thread, but I still don’t know how much power can a stock bottom end hold? I mean all I keep on hearing about is psi of boost and timing. I some what understand about all of that but just need to know hp. And I also am one of those guy they where referring too, about big power and no drivability. But now a little more groan, a little wiser, now see that making big power and can’t drive my car daily is not what it’s all about. Plus with a wife and kids I have to spend my MONEY more conservatively, and wisely. At the end of the day I just want to go out and enjoy my car and have fun… Link to comment Share on other sites More sharing options...
Mingo1 Posted August 6, 2008 Report Share Posted August 6, 2008 I made 351hp and 412 ft lbs tq on mpi tuning with a tec3. Could have made more but clutch I had at the time was slipping. And I drove the car everyday without a hitch. Link to comment Share on other sites More sharing options...

And I drove the car everyday without a hitch. 351 and 412ft, that’s cool thanks. So because of your clutch that slowed you down? If you don’t mind me asking what set up do you have? Because like my self I’m going to be running MPI with a MS and ford EDIS4 to control the spark, full 3†exhaust and port polish head, 25G turbo added fuel pump, and RR FPR with 750cc inj. Also a 4 puck clutch I know, I know it’s a little extreme but that’s what I got the car with, low on cash it was just cheaper for me to get that one re pocked. So my goal was to make about 380 to 400. Do you think this is possible? Link to comment Share on other sites More sharing options...
TainterRacing Posted August 8, 2008 Report Share Posted August 8, 2008 How much power can a stock rebuilt engine handle with MPI & MS comp.? It can handle alot of power just dont Rev up as much as you could with a built motor. I would not go more then 5700 if it was me on a stock motor. Unless you dont mine needing to do it later on.

shift1313 Posted August 8, 2008 Report Share Posted August 8, 2008 it will also depend on what condition you are talking about. If the stock bottom end is in great shape theres not much to worry about. I think the cranks are good to go as long as you dont have any oiling issues.

You need to go t3 or t4 or a combo of the 2 to get in that range. With a smaller mitsu turbo you won't have the volume and cool air you need to make that power. Don't get me wrong it will be fast but unless you use juice I don't think you can expect 350 400 true whp on a 25g. Link to comment Share on other sites More sharing options...

The bot. is in ok shape with a somewhat full re build I say somewhat because there’s a few minor scratches and my wallet wouldn’t permit me to fix them. So I just put new bearings, oil pump, water pump, reused rings that are in good shape from a previous rebuild. All new gaskets, head gasket, ARP head studs and so on. As for turbo, its not small…the front housing is a 70AR, the rear housing is a 63AR. It was a gift so I have to get it sized to be 100% but I know its not small. I was told it should be able to handle over 400….so we’ll see. Link to comment Share on other sites More sharing options...
