i have a 40th anniversary sII gts25t and i have some problems the car first of all has a small air leak from the fuel rail thats a little bent out of shape and its not sealing, but it still boosts up to 7 psi but the car is really slow, a n/a stock sr20 is faster, the car kind of slugs its way up the tach then at high rpms you start to feel a little push but thats about it the compresion is fine the idle is fine it sounds liek all the cyl's are firing its just uber slow, any suggestions? heh i know its not too discriptive but some help would be highly apreciated

the fuel rail isnt stoping fuel flow, the previous owner i suspect tried toforce the fuel rail out or something and bent it upwards 1 of the injectors isnt totally flush with the manifold so its sucking/blowing air through thier only 1 injector though

That cant be good....

I would take 1400r advice or go see mechanic. before you melt a piston. and check that injector?

check your Airflow meter for gunk, and clean with throttle body cleaner, may aswell hit the throttle body with some as well..

may have an exhaust leak in the manifold so listen for that and check.

check your O2 sensor and fuel pressure.

could be heaps of things man, so check them and see how you go.

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
