Right now I am working on an alternative  :oSequential Multiport injection system that will work with the stock PCM ( or ECU ).  It involves a complicated theory that involves the intake valve and the time a which the primary injector recieves the signal to fire.  The Primary and the secondary injectors are controlled seperatly.  During Idle, only the small injector works and is controlled on the ground side by the PCM.  This injector fires on every intake stroke and it is ditributed into the combustion chamber by the movement of the air coming from the turbocharger.  However, I have found a way in which I can control the current flow and allow it go where I want it to go using the same computer signal from the primary injector. In this case the current would be distributed to multiple injectors.  It involves using 4 micro switches intalled near the intake valves, whichwill be activated on the intake stroke ( remember! the PCM also recives the signal to fire the primary injector!) this switch will complete the circuit for the injector at that cylinder and allow a path to ground ( Which the PCM controls ) and POW! injector fires!.  When the intakevalve closes the switch will then open.  Now, this is somthing I am already installing in my car and so far I have only spent $26! 8).  I dont want to continue saying my Idea because it would be unwise and it has taken me a long time of research to figure this out.  As soon as I get it done I will post the results. Do not attemt if you dont know how the system works or you might fry the PCM. :'(

See, I did the T-Racing mod where you put the T fitting it the waste gate vacuum line and that made me run at 14 psi, I then regapped the sparkplugs to .032 and advanced the timing to 9* BTDC. I also did not have time yesterday to list some of the mods I do have like ported exhaust manifold, intake manifold is also ported. High flow fuel filter, gutted pre-cat. See, I have seen turbo cars run compression ratios up to 11.0:1 with engine management. The conquest factory compression ratio is 7:1 and the Montero has a compression ratio of 8.7:1 but in reality the true compression ratio for my setup is around 8.55:1 with the porting and polishing and the valve grind. Now, engine damage occurs only when the temperature in the combustion chambers is to great and this causes the air/fuel mixture to ignite prematurely or burn a hole thorught the piston :-X, ...but... when the tempurature of the mixture in the combustion chamber is reduced then it becomes really efficient. All you need is to have proper airflow, good intercooler, and heat guards and you will be just fine. The pistons from the montero are made of cast aluminum and will handle a great amount of abuse. When I got the 14.8 run I was going 91.23 mph, my 60" was 2.0123 and the 1000" was 13.03. All I know that if you are not breaking parts, you are not racing. ;D P.S. It can handle 14 psi, if you dont think so, too bad.

Well, I finally found out by myself if putting higher compression ratio pistons in my car would benfit it or blow it up. I took the Pistons out of a 1989 Montero and took them to get cleaned and balanced. I took a cylinder head out a 1988 Mitsu Truck and took that to get ported and poliched with a five angle valve jo + resurface. Then I eliminated the Balance shafts, repalced the timing chain, cam pulley, the two guides and chain tensioner. I then ported the throtle body and removed the air splitter in there. Balanced the crankshaft and polished all the contact areas. Well, I put everything back together and decided to add mechanical rockers from a caravan and adjusted them to.006 with a feeler guage. Finally I finished and turned the car on. Worked like a charm. With the 1G MAF and rerouted piping it seemed to work perfect. Well, after a month of breaking it in I took the car to the track. My best time was a 14.8 in the 1/4 mile at 5,400 ft of elevation. I had trouble with traction as the tires were spinning like crazy of the line and I was having trouble shifting to third. I suspect that the could easily run mid 13's with slicks. Considering I used my stock exhaust, no fuel system upgrades (except Venom Injectors), street tires and stock repalcement clutch. not to mention my shocks are gone and the car was rocking like a boat. I think that if I invest in all of the other stuff I could be running high 12's I kid you not 8). Now I know that it is all about taking risks, and when they said my cyl head would blow off I said "SO." With MPI man and a 16g. Oh Man! Watch Out! ;D

I dont know if any one has ever tried but I have been wondering if there is any way that the cars throtle body can be rotaded a little so the intake part faces the front. Â Would it affect the water ports that run through the intake manifold or what? Â It seem possible that it might work.
