SupraDan24 Posted December 2, 2010 Share Posted December 2, 2010 How much will the injectors and water injection set you back? Quote Link to comment Share on other sites More sharing options...
Scott Posted December 2, 2010 Share Posted December 2, 2010 400ftlb at 2600rpm is very impressive. I thought that too, but what a lumpy dip just after. Are BPU graphs normally like that? Quote Link to comment Share on other sites More sharing options...
SupraDan24 Posted December 2, 2010 Share Posted December 2, 2010 400ftlb at 2600rpm is very impressive. What sort of figures would you say would make this cost effective Jamie and a viable option to going Single. Quote Link to comment Share on other sites More sharing options...
Scott Posted December 2, 2010 Share Posted December 2, 2010 What sort of figures would you say would make this cost effective Jamie and a viable option to going Single. None really, not at that price anyway. You can get a single kit for very similar cash. Quote Link to comment Share on other sites More sharing options...

To add to Scott's question, do you always get such little increase in torque with the 2nd tubby? Quote Link to comment Share on other sites More sharing options...
SupraDan24 Posted December 2, 2010 Share Posted December 2, 2010 Yeah, but there seems like alot more work involved in going single, which leads to alot of extra costs. Unless FullThrottle is just doing this on a budget? Quote Link to comment Share on other sites More sharing options...

SupraDan24 Posted December 2, 2010 Share Posted December 2, 2010 Any examples? I can't think of much that would make any difference to be honest Pretty much every build thread i've ever read. Even guys going for moderately low power ie Matt Wallis, the costs seem to be pretty high. Seems all this guy has spent so far is 2k on the turbos, and just needs bigger injectors. edit: and the scyvecs of course, forgot about that.

Seems all this guy has spent so far is 2k on the turbos, and just needs bigger injectors. He has a Syvecs ecu, mapping and dyno charges, he is also going bigger injectors, everything a small single needs. Quote Link to comment Share on other sites More sharing options...

Lol Ok..... $3k in the US will work out not a kick in the shirt off of £3k by the time you factor in shipping and taxes. £3k would get you a single kit including everything required to fit the turbo onto a stock car. Everything else required to get 500+HP will be exactly the same. Fueling upgrades, ECU upgrades, Clutch Upgrades, Cooling Upgrades, Exhaust Upgrades etc etc etc etc etc. Bolting on a turbo/turbos is the easy part Quote Link to comment Share on other sites More sharing options...

So this has no real benefits over a small single then. Got there in the end Quote Link to comment Share on other sites More sharing options...

SupraDan24 Posted December 2, 2010 Share Posted December 2, 2010 Seeing as i already have a walbro pump, an apexi power FC and an uprated clutch, can i expect my costs to be relatively low if i went small single? Quote Link to comment Share on other sites More sharing options...

SupraDan24 Posted December 2, 2010 Share Posted December 2, 2010 Cool, well that gives me something to think about then. Sorry for the thread hyjack FullThrottle, look forward to seeing your results mate Quote Link to comment Share on other sites More sharing options...
fullthrottle Posted December 2, 2010 Author Share Posted December 2, 2010 it wasn't so much of a cost thing but really wanting to keep with the original configuration if i added it up then i guess i am probably in it for 5 grand easy when you add up the the turbo kit, ecu, exhaust, intercooler, bov, i have already bought the injectors and fuel pump they just didn't arrive in time for ryan, i bought a bosch 044 pump and sard 650cc injectors then i will get water injection this week and install it in january ready for ryan then we will see what we can push it too but we should go past 500bhp Quote Link to comment Share on other sites More sharing options...
Ryan.G Posted December 3, 2010 Share Posted December 3, 2010 I must admit also when Andres said to me about this kit i thought it was just another set of hybrids but these are certainly different. They use the standard compressor and exhaust housings but have been seriously machined out to fit the gt28 cores and they are definatly water cooled as new water pipes have to be installed. They spool so quick so would say they are almost sure to be DBB. Only thing i worry with the kit is the exhaust temps and exhaust pressures as the standard exhaust housings and manifolds are restrictive and on other cars running over 1.2bar i have seen over 950c on the egts. So have suggested to andres to fit a WI kit and maybe to go with some 800cc injectors and running E85 if it is available where he lives in europe. The exhaust temps with E85 drop by about 20% so would be a good route to go with big boost. Ryan Quote Link to comment Share on other sites More sharing options...
Nic Posted December 3, 2010 Share Posted December 3, 2010 Noticed the car is a UK spec. Is the wastegate able to cope with the increased flow? Would be interested in seeing some pics of the turbos installed. Quote Link to comment Share on other sites More sharing options...
Tee from China Posted December 3, 2010 Share Posted December 3, 2010 (edited) Hi,have you gone for the US (UK) specs as per Jamies link or these? https://www.speedforsale.com/supraparts/speed-for-sale-bnr-jdm-gt28-style-hybrid-stock-twin-turbo-upgrade-p-635.html?osCsid=1g44tnn0m0itj33o0lj8qejho1 If the former did you buy some s/h UKs to return? Edit, Ignore me - just seen his car is a UK model! Edited December 3, 2010 by Tee from China jumped the gun (see edit history) Quote Link to comment Share on other sites More sharing options...
fullthrottle Posted December 4, 2010 Author Share Posted December 4, 2010 yes my turbos are the uk/us spec and no i didn't send them a set of turbos i still have my old one thanks Quote Link to comment Share on other sites More sharing options...
Ian C Posted December 4, 2010 Share Posted December 4, 2010 Looking at that graph I'd say 1) get some cams in there to liven it up after 5500rpm Also, a nice 264 or thereabouts exhaust cam should help EGTs with those housings. 2) The torque dip is probably the prespool for the second turbo - if you are running higher than stock boost on the first turbo, you might want to put a restriction or bleed valve in the EGBV system so stop it venting so much boost when prespooling the second turbo. That's quite an impressive dyno for sequential twins -Ian Quote Link to comment Share on other sites More sharing options...
