C2 issues seem to be pretty well fixed.
Bump for the forum.
Looking into adding a SRI section. Maybe a feedback section?
Say, if you have a C2 chip, or a eurosport intake. You can give your feedback on the item, and I can add it to a list. Something like
Eurosport intake , , ,
Something like that.
Yeah I have the 94 golf im pretty sure its obd 1 also so which chip is thatbthe 270, n damm I had another question but I keep blanking n idk if anyone had a problem with their speedometer not working mine seems to work 2% of t he time usally if I go over a bump it will stop working or just wont start at all, n I have some kind of sound like keys jingling in the back left side I cant figure out what it is
The 270* Autotech cam is a very nice piece. Good power, good idle. For OBD1, you don't need HD valve springs. Just remember you'll need to change the lifters, (~80 dollars).
Sounds like your cluster is bad. Go get one from a 93-98 Jetta/Golf/Cabrio/GTI and swap it in. It's 6 screws total.
I know from experience that the USRT piece is very very nice.. I don't know if any other companies really make a "good" one. I don't want to bother adding a place that says "buy a generic DIY intake manifold" because it's definitely more involved than the average person can do, and there is science behind it. I wouldn't run a home made SRI, unless I built it and made it from R to D.
It's not hard to do... if you can make measurements and can weld, or have somebody weld for you it opens up a whole world. Screw paying $700 for something that I built for $300, and **** on it in terms of flow.
Colm, this thread shouldn't be carried with the attitude of "something your average person can't do and won't be included" kind of thread. Those kind of decisions should be left up to the people attempting such things. If they feel it's too much for them well then maybe it is, that's not to say it shouldn't be included among this resource bin for ambitious people who don't want to puss(y) foot around and actually want to make power.
I'll try to look into some DIY kits. I know BBM sells one, and I'm sure ebay does too. Using the stock lower intake manifold/fuel rail makes things a bit easier if possible.. I suppose it wouldn't be too hard.
I just think they can go wrong easily and you can starve cylinders if you don't know what you're doing, you know? It's like playing with fire.
the mk4 lower manifold is smaller at the head than it is at the union of upper and lower creating a venturi effect
thus making it a better place to start a diy sri
just a thought
The HKK ones were like $400 or less with core when they were being made. I don't think they were that sophisticated of a design. The USRT ones were an improvement, but the same guy, Greg Haley from HKK/SVi Welding, was making them as far as I know. The latest USRT long runner ones are someone else I'm pretty sure. I don't remember whole story but I remember people having problems getting work and parts back from Greg. Schimmel makes them too. I don't know about for a 2.0, but money talks.
The only thing I'd suggest if you decide to build your own or get a custom one is to look into a dual plenum design. It'll distribute the air more equally at the runners/head. May not be too important for an N/A build, but for FI it could make a considerable difference.
THe first version's of Greg's manifolds were a basic log welded to a lower stock piece. Then went to a measured log, stock bottom, domed with pressed-bell runners. THe latter is what was rebranded as USRT manifolds, and one of the models I dyno tested. He made the custom manifold that I ran (and sold to Zero).
THere was a huge pissing match (which I wont get into due to involvement) between Greg/HKK and Scott/USRT over production, so USRT went with various other welders and claimed a "different" design; so began the 'LRI'. All that consisted of was the bells integrated into the plenum wall as opposed to the original design of them protruding into the plenum. (
The SRI manifolds are soooo good for power. I wish I could run mine with my BBM kit, but, alas, I cannot. I'm stuck with a ported MK4 manifold.
