Justin Posted October 31, 2002 Share Posted October 31, 2002 I want 450 bhp on my supe. What extra objects do I need so I can start saving up? HAVE: Nur Spec with restrictor plate Full De-Cat TRL FCD Speed Delimeter Currently running just under 18 psi NEED?: Intercooler? Hybrid Turbos? What other essentials? (not good to have's) Thanks guys. Quote Link to comment Share on other sites More sharing options...

mrboost Posted October 31, 2002 Share Posted October 31, 2002 don't bother with the UK injectors go even bigger and get her upto 550!! Boost Quote Link to comment Share on other sites More sharing options...

Boost I assume you mean 550 bhp not 550cc. Cams would be needed too. Quote Link to comment Share on other sites More sharing options...
mrboost Posted October 31, 2002 Share Posted October 31, 2002 oh yes! 550bhp. Quote Link to comment Share on other sites More sharing options...
Andrew Dunk Shaw Posted October 31, 2002 Share Posted October 31, 2002 Hi Justin, All you need mate is lots of ££££'s then just give it to Leon:) Regards Andrew(Dunk)Shaw Black uk mkiv tt Quote Link to comment Share on other sites More sharing options...
Justin Posted October 31, 2002 Author Share Posted October 31, 2002 That is about the size of it Andrew mate. I probably will give it to Leon to do the work anyway. I just want to get a handle on what is needed and what things are just luxury to keep to the costs to a minimum. Cheers Quote Link to comment Share on other sites More sharing options...
Branners Posted October 31, 2002 Share Posted October 31, 2002 It all depends how long you want the turbos and engine to last and also for how long you want to run max power. I knew running 1.4kg boost on my import would reduce the life of the turbos and my plan was to put hybrids on when the stocks blew. I made sure to fit a FMIC to keep charge temps down a bit and my next plan was to fit 550cc injectors to help with fuelling. I never held the car at max boost for too long so the EGTs probably never got up high enough to really do any damage, but if you are somebody who drives flat out for long periods then you need to make sure you have sufficient fuel and cooling to deal with the heat. To get a reliable 450bhp you will need hybrids, a good FMIC and improved fuelling. JB Quote Link to comment Share on other sites More sharing options...

A RELIABLE 450 is what I want. So I will also need 550 cc injectors and a UK spec fuel pump is this correct? Quote Link to comment Share on other sites More sharing options...
Matt C Posted November 1, 2002 Share Posted November 1, 2002 Just to jump in here and it may also help Julian a bit too maybe (Excuses, Excuses!). To upgrade to UK 550cc injectors what is actually needed other than the injectors themselves...? Obviously the fuel pump.....anything else. Probably been done to the death this, sorry if it has! Keeping an eye on the board through the nights! Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted November 1, 2002 Share Posted November 1, 2002 Yeah a resistor pack. The injectors are a different impedance. Quote Link to comment Share on other sites More sharing options...
Ian C Posted November 1, 2002 Share Posted November 1, 2002 And the associated cabling to wire it into the engine loom. And nerves of steel to cut into said loom. And someone with a decent O2 sensor and some experience to set up the fuelling properly. -Ian Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted November 1, 2002 Share Posted November 1, 2002 And a SAFC or similar to trim the fuelling & preferably a wideband o2 sensor if you want meaningful readings:p Quote Link to comment Share on other sites More sharing options...

Ian C Posted November 1, 2002 Share Posted November 1, 2002 Can I point you at pages three and four of an older thread where myself and GavinL knocked out the cost of taking a bog stock j-spec to a 450bhp hybrid beastie. This was a 'done-properly' excercise, where the turbos are operating in their efficiency range, the fuelling is adequate, properly set up, and checked, and the EGTs are within an acceptable range. There is some useful info in there. See what you think. Of course, deduct what you've got already from the bill And in case Gareth reads this thread, -Ian Quote Link to comment Share on other sites More sharing options...
Justin Posted November 1, 2002 Author Share Posted November 1, 2002 Hmmmm, cheers for that Ian, good reading. Looking like around 5K for a 100 reliable bhp then. Don't think I can even justify that to myself which is usually very easy. Perhaps I'll just get an intercooler and Stillen bumper for now :( Another controversial one for you guys. Does putting an intercooler on a bpu J-Spec give you more bhp/power/acceleration? Seems like MKIV.com think it does. (Don't want to start a MKIV.COM vs MKIVSUPRA.NET war here!)

Gaz Walker Posted November 1, 2002 Share Posted November 1, 2002 Originally posted by matt How many RHD j'specs do ya think are in the states? Yeah! The cost of $28k just to import one (thats not including the car!) is enuff to put anyone off! Gaz. Quote Link to comment Share on other sites More sharing options...
Branners Posted November 1, 2002 Share Posted November 1, 2002 and getting back to the question a good FMIC will reduce charge temps which means there could be some additional power to be had on a warm day. I used to find a big power drop on a hot day with a stock IC, changed to an S-type and the car seemed to keep a decent level of power on a hot day as well as on a cold day. So it can give some extra power but its more noticeable on a hot day. I would say to get to 400bhp (which believe me is pretty damn quick, my import must have only been about that), should cost about £3k, FMIC, decat and exhaust and run up to about 19psi should give you a nice run of power.

Ian C Posted November 1, 2002 Share Posted November 1, 2002 I plan on dyno'ing mine soon, now that my boost spiking is sorted and I've re-setup my boost controller, so I'll let folks know how it goes. Should let people know if hybrids are worth the cash or not -Ian Quote Link to comment Share on other sites More sharing options...
