tttttada Posted September 12, 2008 Author Report Share Posted September 12, 2008 how much did your wheels cost and where did you get them from.and really nice carThank you for your kind words.I bought them in Japan so I'm not sure if it'll help, but they were 89000YEN (approx 470GBP) for four wheels Quote Link to comment Share on other sites More sharing options...
tttttada Posted September 12, 2008 Author Report Share Posted September 12, 2008 (edited) As promised, here are the rest of the pics of my exhaust system.Raceland manifold prepared to be fully wrapped2nd branch (4 ->2) cut and welded to clear oil pan.Lengthened O2 sensor -> flexipipe -> sport cat Edited September 12, 2008 by tttttada Quote Link to comment Share on other sites More sharing options...
tttttada Posted September 12, 2008 Author Report Share Posted September 12, 2008 (edited) Cam cover taken off for a full P&P and installation of Schrick cams.Pic of intake manifold and gasket.It seems that all the previous info about the intake ports were correct.There is hardly any port matching to do on this side.Probably about a millimeter all around.But here is where it gets interesting.There is a TON to be ported on the exhaust side.Here are some measurements I took (remember the exhaust ports are oval shaped and are shorter vertically)Gasket ports: 30.0mm(H) x 43.5mm(W)Manifold ports (from left to right)29.5mm(H) x 51.0mm(W)26.5mm(H) x 49.5mm(W) <- WTF29.5mm(H) x 51.0mm(W)29.5mm(H) x 51.0mm(W)Head ports: 23.5mm(H) x 32.0mm(W)As you can see, when matched to the gasket, the exhaust ports can be ported 6.5mm in height and 11.5mm in width. And when matched to the manifold another 7.5mm in width!!!! THAT IS HUGE!!!(the Raceland manifold has one small port. Probably a manufacturing error.)We are still debating on whether we should port match to the gasket or the exhaust manifold.Will keep you posted.

tttttada Posted September 24, 2008 Author Report Share Posted September 24, 2008 (edited) The head came back yesterday.As you can see, I ended up matching the ports to the gasket.So the width is now 30.00mm (ported 6.5mm) and the height is 43.5mm (ported 11.5mm)For those wondering, that is more than a 70% increase in port area, which is HUGE.(area of oval = pi*a*b where a = half length of major axis (horizontal) and b = half length of minor axis (vertical))before = 590mm^2 now = 1024mm^2The valves were all pulled and chambers were also ported.Had it gas-flowed, but decided against polisihing it.Some engineers have told me that it doesn't make a difference, as far as flow efficiency goes.At any rate, the head is on the car now and the Schrick cams are being assembled.In the meantime, the exhaust mani has been wrapped.After that, off to the ECU tuner. Will keep you posted. Edited September 24, 2008 by tttttada Quote Link to comment Share on other sites More sharing options...

tttttada Posted October 9, 2008 Author Report Share Posted October 9, 2008 We added a duct to the CDA intake, and routed it to the lower bumper grill.I'm hoping it'll lower the intake temperature.The car came back from the cam install, and I test-drove it before sending it off to the tuner.Bottom line: even without the tune, the car is MUCH fasterThe midrange torque from 3000RPM is ridiculous, and it pulls hard until redline.The flatness of power between 5.5KL-7K rpm is gone; the engine really wants to pull hard even past 7000+rpm.I will tell the tuner to set the fuel cut-off point at 7500rpm.Overall I cannot be happier of the results.I was expecting some torque loss from the extra duration of the cams, but the P&P really set this engine alive.I have high expectations of what the tuner can add to the output.Will track the car on the 18th. Can't wait.So, for those of you wondering, this is a highly recommended mod!! Quote Link to comment Share on other sites More sharing options...
richardn Posted October 9, 2008 Report Share Posted October 9, 2008 do you know if that rear sway bar will fit on non gtis as it looks as if it is just bolted to the bottom of the suspension struts,and then two more brackets holding it in the middle Quote Link to comment Share on other sites More sharing options...
