chrisvr6t 19 Posted October 24, 2013 Report Share Posted October 24, 2013 if I had the option I would go for the billet 6262dbb with 4" anti surge with t4 exhaust housing 0.82ar or 0.96ar but that's just me.. will be quite laggy but if u running a standard box lag is your friend lol Link to post Share on other sites
Radodb 4 Posted October 24, 2013 Author Report Share Posted October 24, 2013 sweet thanks for the help lads .. TURBO ORDERED... .. as for wastegates / blow offs would you say would be a good combo? Link to post Share on other sites
MaidenVR6 26 Posted October 25, 2013 Report Share Posted October 25, 2013 38mmTial or 39mm Precision. T4 0.81 or 0.96 will be great fun ! Link to post Share on other sites
Radodb 4 Posted October 25, 2013 Author Report Share Posted October 25, 2013 38mmTial or 39mm Precision. T4 0.81 or 0.96 will be great fun !I ended up going with a Precision T3 A/R 0.82..I thought a T4 A/R 0.84 would be just to much lag... Or Am I wrong?? If so I best get in contact with them ASAP and change my order before it's to late Link to post Share on other sites
shawy 3 Posted October 25, 2013 Report Share Posted October 25, 2013 I run a 79lbs min turbo 790bhp on a 2.3 4 cylinder engine which had full boost at 4.5k surely these 2.8 v6 engines should spool early as hell or is it because you only run lowish boost .. not seen many v6 turbo graphs .

MaidenVR6 26 Posted October 25, 2013 Report Share Posted October 25, 2013 T3 0.82 will have full boost around 3200 rpm. Your gearbox will not like that.Personal choice would be T4. 0.82 Link to post Share on other sites

Radodb 4 Posted October 25, 2013 Author Report Share Posted October 25, 2013 Would a LSD help?Sent from my iPhone using Tapatalk - now Free ill be going 4wd and using the R32 or 4motion box T3 0.82 will have full boost around 3200 rpm. Your gearbox will not like that.Personal choice would be T4. 0.82 ahh right i see when would a t4 A/R 0.84 make full boost?? i best get in touch with the selle and change my order haha..

Radodb 4 Posted October 25, 2013 Author Report Share Posted October 25, 2013 iv managed to change my order to this ( below ) T4 .84 A/R Divided V-Band Compressor Wheel: Inducer 2.44" (62mm) Turbine Wheel: Exducer 2.437" (62mm) Ported S-compressor cover (.70ar) would the ATP log manifold accept the T4 im guessing it would with it saying T3/T4... ATP cast VR6 manifold designed for T3, T3/T4 or T04 turbo applications. Will work for both MK3 and MK4 VR6 cars. Hi-temp material and thick walls prevent cracking under severe heat. Pricisely tapped for M8 x 1.25 for the 2 bolt wastegate flange and threaded M10 x 1.5 for both T3 and T04 bolt patterns. ** External wastegate flange can be blocked off with blockoff flange if using this manifold for internally wastegated setups Link to post Share on other sites
VIW28 29 Posted October 26, 2013 Report Share Posted October 26, 2013 Good turbo choice Also, for wastegate I would go with a 39mm Precision one. I've had both it and Tial and found the Tial to be way out on spring pressure whereas the Precision was spot on. Link to post Share on other sites
Radodb 4 Posted October 26, 2013 Author Report Share Posted October 26, 2013 glad i changed my mind now.. did you use an oil restrictor?? Link to post Share on other sites
Radodb 4 Posted October 29, 2013 Author Report Share Posted October 29, 2013 will mk4 24v vr6 ARP bolts be the same as the 12v?? iv ordered all 12v but now have the chance as a cheap 24v 4motion saves me cutting up the mk3 to fit the 4wd. could put more money into the engine and box in form of a better manful supporting mods and front and rear LSD...if not ill be selling / returning the 12v bits and bnuying 24v... dam friends tempting me lol Link to post Share on other sites

shawy 3 Posted November 7, 2013 Report Share Posted November 7, 2013 It was on a 2.3 subaru engine running 28 psi made 690 bhp made full boost at 4400 rpm ..Was thinking of fitting a t04z to my vr6 but they don't seem to spool very well for cylinder engine size ..And with them not revving so high they need to spool fast...But I've not seen any proper builds with decent fuel and a proper engine management system so that may help a lot also only seen 12v heads no graphs for 24v builds ...

lowvr 0 Posted November 17, 2013 Report Share Posted November 17, 2013 Sounds interesting Have a look at some of Bill Schimmels work of schimmel performance turbo..you may find it also interestingHis builds are pretty "full on" ...proper stand alone management with fueling to compliment 9k rev range.

chrisvr6t 19 Posted November 20, 2013 Report Share Posted November 20, 2013 I would get hold of AME-racing but be ready to use google translate unless u can speak german lol, having seeing their cars in the flesh I would defo contact them for any questions you want to know about head flow.... their polo ran a 8.9sec 1/4mile at vw action this year at santa pod and mk3 golf 9.0.... or you can try contact lugtronic over in the states Link to post Share on other sites
RBPE 198 Posted November 28, 2013 Report Share Posted November 28, 2013 If you were to build a road car to anything over about the standard 7000rpm rev limit then I would say NOOOOOOOO!First and foremost you can get over 900hp on the standard rev limit, it has been done (turboimpression being one), you're also going against the undersquare design of the engine. You are also increasing greatly the likelyhood of damage due to the offset and highly increased piston speeds on an undersquare engine.... not needed and goes against the proper tuning principles of the VR6 engines.... i.e. undersquare-esque tuning. Get everything properly aligned and tolerances done properly when re-building is the first step, bearings and stressed reciprocating parts such as the rods - e.g. ARP rod bolts for better clamping forces or get a set of 4340 rods, they are about £400 odd with the ARP bolts, gasket as UM said will handle most boost levels for daily, 4032 pistons are better for daily's than 2618 or 7075 if going the forged route due to thermal expansions, valve-train I would make sure is refreshed just to stop valve float and the like on boosted and worn engines - anything under 550-600hp though I would not go overboard with the engine and just make sure it is all in good working order.
