![]() ![]() One of the build I know of was running 36PSI and made well over 800WHP. 9:1CR might be something to look at a little but I am pretty sure others are running like 36PSI on 9:1. Running standalone would save me from having the cost of software again plus the internals will hold. I want to build the trans before I put too much power down and I should be ok to throw more than 30PSI with some different injectors and a second bosch 044 pump. Either way if I don't make the power that I want I can throw more boost at it later. Yea I wonder if the larger displacement would make any difference. Forgot to take a pic before putting in 2 valves.Īutotech HD springs and TT titanium retainer with larger supertech exhaust valve and stock keepers. Theirs is not bad but you can see the difference between the bowls and the bottom where they go into the runners. Here you can see the difference in their polish vs mine. You can see for yourselves and I would refer people to use this shop if you have a little bit of time to wait for the work to be done. The work is not bad by any means but just not as good as mine in my eyes. They said it should only take about an hour so I told them that is fine and to just get it done. The day I picked it up they called and asked if I wanted to take it and finish the port work or just have them do it real fast. So as I expected, the bowls for the valves did not match up to the new seats but the machine shop did not want to cut out the old seats before I ported. I then got a good start to the bowls.įinished the bowls and started to polish. You can see I only went to the valve guides in those pics.Īfter porting the runners, the machine shop heated the head and pressed the guides out. Ports not touched but I traced the gasket to show the difference in size on the exhaust side. Next I got some work on the exhaust side done. Next was to get the exhaust ports up to the valve guides and then taken to the machine shop to remove the guides and the seats. Polishing will be done after all porting is completed. That is what I have for actual pictures of the porting at this point. Then begin to port all the intake runners. I decided the markings was not good enough and bolted the old gasket to the head. I did make the ports a little bigger but the main focus is on the casting marks from factory. There is casting marks that need removed and also you can smooth a lot of transitions in the runners. The machine shop also surfaced the head.įirst I traced the gasket to the head to match it but that's not all you need to do for effective porting. The seats and guides were changed by a machine shop. The port and polishing and all building/disassembling was done myself. ![]() ![]() Metal Valve Cover (stock was plastic, did it for looks as I will polish it later)Īll New gaskets in the top end and exhaustĬustom SS studs from ex manifolds to downpipe ![]() Re-grease accessory belt tensioner bearing Port and Polished head, Intake manifolds, exhaust manifolds, downpipe The list of mods includes.īFI PEM chip for 262's and high compression (MK4 gasket), Also removes SAI and 2nd O2. I would say 12's but my friend drove it and thinks high 11's. I have not been to any tracks yet but it definitely is faster than before. The car is built to equal ones that have proven low 12s 1/4 miles and some in the high 11's as an all motor NA car. I also have some chatter from cam to followers and just wanted a little more power now. Well it came time to do my timing chain guides and my throw out bearing as they were both making some noise. ![]()
