nismo.capri Posted February 1, 2007 Share Posted February 1, 2007 hmm true,im going mostly by what ive been reading on the z forums. aslo the ecu dude (who several people on the forum seem to be happy as with) swears by 3'' straight off the turb into one, but dont really wanna rip the engine out (bay is packed as all fuck) so prob just go off the manifolds like in your pic. pretty much same as you got there. Also the exhaust guys i been talking to reckon 3 is good for it, smaller like 2¼ if it was twins. cheer man Nothing beats actual experance! My VG is a DET so it will be running a single exhaust from the turbo back, hell interested to see what you think sound and power wise The 3 inch was all good on the clevo.... mainly for aureal pleasure Quote Link to comment Share on other sites More sharing options...
nismo.capri Posted February 1, 2007 Share Posted February 1, 2007 interesting about the cooling gasses further down tho. wasnt aware of it. i was thinking the cooler you keep it the better Bigger diameter exhaust = more volume = slower gas spped = more time for ex gases to cool down, cooler = more dense (just like intakes) more dense = heaver so to push it out takes more energy. So you can see how if an exhaust is too big it can cause back pressure. how much depends on all sorts of things which is why Gary likes running access points on his exhaust so he can measure it. This is all upper end bleed every last HP stuff and still argued about IIRC. Quote Link to comment Share on other sites More sharing options...

This is all upper end bleed every last HP stuff and still argued about IIRC. true. true, makes perfect sence. will see tho in practice if its good or bad i guess. let you know. Im picking it wont be too loud with the turbos and all, and the 6 sounds so damn nice even std. what turbo you gonna run on yours anyways? as far as power goes im not expecting tooo much from just the exhaust, more about it working with a pod and boost/ecu tweek later. shall dyno it as well once its all sorted this month Quote Link to comment Share on other sites More sharing options...
Gaz Posted February 1, 2007 Share Posted February 1, 2007 MM VG30. Run twin GT35/40r's So, who wants to give me their AFM for $10? Quote Link to comment Share on other sites More sharing options...
nismo.capri Posted February 1, 2007 Share Posted February 1, 2007 what turbo you gonna run on yours anyways? Good ol' T3 .68 ex housing and a T4 compressor.... still havn't been able to ID the compressor wheel but looks good for 400-500 hp as far as power goes im not expecting tooo much from just the exhaust, more about it working with a pod and boost/ecu tweek later. shall dyno it as well once its all sorted this month Awes can wait to see your results!

nismo.capri Posted February 1, 2007 Share Posted February 1, 2007 MM VG30. Run twin GT35/40r's I wish! ....I brought a twin turbo setup and it doesn't fit the heads the DET runs the NA heads not the TT heads. Didn't really matter as the turbo hit the steering So, who wants to give me their AFM for $10? Sorry never had it. BTW did you get my email?

Gaz Posted February 1, 2007 Share Posted February 1, 2007 Think the De ones were the old ones. What ya going to use the N/A engine in? If going N/a Id try find the later one with a couple extra valves Not so important on turbs as ya just up the boost. Ahh the joy of a turb Quote Link to comment Share on other sites More sharing options...
davidian Posted February 1, 2007 Author Share Posted February 1, 2007 dont know if theres been more engine changes, but i think in 95 they changed to non variable timing units. was reading on some site the best ones are 93-95 but fuck knows, its all "web info" Quote Link to comment Share on other sites More sharing options...
Gaz Posted February 1, 2007 Share Posted February 1, 2007 Yuh damn web info, at the mo im trying to find out about ca18det cam or cams upgrades from the ca18de or ca16de... keep running into contradictions so end of the day I dunno whats what!

nismo.capri Posted February 1, 2007 Share Posted February 1, 2007 Think the De ones were the old ones.What ya going to use the N/A engine in? I brought it for $500 as I needed a flywheel and the sump/pickup. The one had had the well at the wrong end. If going N/a Id try find the later one with a couple extra valves It's got 24 all ready! Not so important on turbs as ya just up the boost. Ahh the joy of a turb Forced induction allllllllll the way .....I have to keep talking myself out of supercharging the van.
