6potmkII 0 Posted April 22, 2007 Report Share Posted April 22, 2007 if your not doing it yourself, sounds like alot of money for little gains if you ask me. personaly id maybe wait a bit, put a bit more money on top and find a charger Link to post Share on other sites
gibbs85 0 Posted April 22, 2007 Author Report Share Posted April 22, 2007 Well I can do everything except the port polish and valve job myself. I live with 2 mechanics and we have everything you could possibly need to work on cars (except a lift And those mods arent going to be nearly as costly or cause reliability issues on my one and only daily driver like forced induction will. When the turbo bug finally bites Im just going to get a 240sx or an xr4ti. The roomate who sold me the bora has done a sr20det swap. My other roomate is big into stealth r/t's, he's owned 3 at once. Justin has a 3000gt and a stealth r/t in the shop that he's selling also. Besides that I'm only looking for a marginal gain in hp/tq. From those mods listed above I can expect atleast +50 hp/tq with a better fuel pump. And those parts are gonna cost me under 2g american. Compared to 5g for a charger kit : / Then there's always nitrous Link to post Share on other sites
antera309 3 Posted April 23, 2007 Report Share Posted April 23, 2007 I used to have a pair of Schrick 268 cams in my VR. Along with a BMC CDA filter, milltek exhaust and raceland 6 branch manifold and a custom remap it made a smooth, reliable 205BHP with no noticable loss of fuel economy or road manners.Later on, I sold the cams and went supercharged. This turned out to be a very bad move which almost wrecked my engine. I wish I'd have held onto the cams now.Likewise, head work is alway a good idea, especially if the head needs a recon anyway.

gibbs85 0 Posted April 23, 2007 Author Report Share Posted April 23, 2007 Would you recommend the 268 cams? BTW that cabrio in your sig looks really nice. Is it possible to remove the roll bar? It would look really good then Link to post Share on other sites

If you see 20+ bhp, you should be happy.And why do you need a bigger fuelpump? Link to post Share on other sites
gibbs85 0 Posted April 23, 2007 Author Report Share Posted April 23, 2007 50 Might be alittle overzealous but the port/polish/valvejob alone will be over 20bhp. Link to post Share on other sites
gibbs85 0 Posted April 25, 2007 Author Report Share Posted April 25, 2007 Ok so there is a performance shop the next state over to me that has produced the fastest/most powerful vr6's in the states. Its called schimmel performance. They have 263 cams available. Can anyone explain the difference to me between schimmel 263 cams and schrick 268 cams? What would be the benefit of one vs another? Thanks Link to post Share on other sites

Thanksthere 2 differant manufacturers that will probably use near enuff the same material (unless schimmel's are reground i dont know), The only major (and most important) differance is the duration of the cams in this case either 263 or 268. this determines how long the valves driven by these cams stay open for. in simple terms for every revolution of the camshaft (360 degees) the teh schimmel cam will stay open for 263 degrees of one 360 degree revolution, and the shrick, 268 degrees one revolution.ud probably be slightly better off with the 268 if you plan on keeping the engine naturaly aspirated.

Bazmcc 0 Posted April 26, 2007 Report Share Posted April 26, 2007 Baz' date=' R32 Cams? Compared to Shrick? Really?[/quote']I don't know what you mean by that. Is it a question?I've just been wondering if the R32 cams would fit a v6 and if the durations were different but I think they might be the same. I'm parting out an R32 engine at the minute.Baz Link to post Share on other sites
6potmkII 0 Posted April 26, 2007 Report Share Posted April 26, 2007 i doubt R32 cams would fit in the 12v vr6 head as R32's have 24vand i have jus realised we r talkin about a 24v lol... Link to post Share on other sites

gibbs85 0 Posted April 26, 2007 Author Report Share Posted April 26, 2007 I was researching cams and came accross a page for bmw cams. There were like 6 different sets available from 254 to 288 duration. The descriptions said that the lower cams were for street / occasional track use. And as the duration went higher the description became more for dedicated track use (higher rpms). So Im thinking that for N/A street use the 263's would probably benefit me more.and a 2000 is a 12v isnt it? Link to post Share on other sites
