Guest michaelt86 Posted January 4, 2008 Share Posted January 4, 2008 i dont have one fitted but i ahve done some research and although u can get plenty of power from a single turbo, the twin is still awesome, get the power all the way throught he range, small turbo for low revs and the big one for higher revs. Also, you really are better off saving up for a TT beacuse although a turbo conversion is good you will still ahve a lower compression than a Factory turbo beacuse the block is built for it and a converted engines isnt so will never be able to run at a higher boost to really unleash all the horsepower its capable off, this said, a turbo conversion will be by no means slow in anyones estimation. Hope it helps Quote Link to comment Share on other sites More sharing options...
Scooter Posted January 4, 2008 Share Posted January 4, 2008 That particular kit is for a jza70, ie a soarer or Mkiii import with the 2.5l engine............ On the subject of NA-T i think you need to think and research carefully if you want to end up with more BHP than a BPU TT. Quote Link to comment Share on other sites More sharing options...

Matt _Aero top_ Posted January 4, 2008 Share Posted January 4, 2008 Do a search mate on N/A-T conversions or N/A-TT conversions this topic has been covered times many . But to answer ya question briefly ..... N/A-TT , contact jezz he does them 3K all in fitted inc gearbox . N/A-T , On a budget and to fit it all yourself 2kish or 3 to 3.5k to get someone like turbo fit to do it , but then theres extra costs like mapping etc .

To flow the same amount of air, a twin turbo kit would use 2 small identically sized turbos, a single kit would use 1 larger turbo. The twin set up is a lot more complicated, requiring a lot more parts and would have similar (if not slightly more) lag compared to the single turbo.

Powerhouse Racing and Boost Logic both make good quality kits. Forget about any cheap ebay kits, they are just not worth it. It isn't as simple as just bolting on a turbo kit, there are a lot of supporting parts required, so be prepared to spend £8k+ to do it right, just off the top of my head here's an idea of what you'd need. Turbo Kit (needs to include intercooler and piping) Oil/water/breather lines Thicker head gasket (ideally completely rebuilt engine with lower compression pistons) Fuel Injectors Fuel Pump Fuel pressure regulator Fuel lines ECU + sensors Boost Gauge, EGT Gauge, AFR Gauge. Boost controller Clutch Spark Plugs Oil & oil filter Various gaskets and fittings Labour for installation Mapping Then there are other things to consider; what condition is you engine and cooling system in at the moment, as any increase in power is going to put extra strain on components such as radiator, water pump, thermostat, oil pump, oil seals, etc. Quote Link to comment Share on other sites More sharing options...

Joeatphr Posted January 5, 2008 Share Posted January 5, 2008 At the moment we're working on a new NA setup that will be a perfect fit in the US and hope to get it fitted in with the Jspec to make best of it! Will have more very soon! Cheers, Joe Quote Link to comment Share on other sites More sharing options...
philstowell Posted January 5, 2008 Author Share Posted January 5, 2008 well thanks every one, like i said im just thinking of the idea, i knew it would be costly and know that extra bits would need changing and the engine and cooling system would need upgrading with all the cams and gasket and all that, i was just wondering if that on the 1st post was a decent type of turbo? cheers for the input people and my pennies are a saving? say for instance? on any vids where you hear the sups really winding up before they beast it down the road spitting fire, do twins and singles both do that the fire spitting and kind of whistling? again cheers all phill Quote Link to comment Share on other sites More sharing options...

Cheers, Joe I believe the biggest issue with the US kits is the steering column hitting the manifold given the fact that we drive on the correct side of the road Get round that issue and it will be much easier.

Lebsteif Posted January 5, 2008 Share Posted January 5, 2008 Which choice the best is for you depends on you expectations and budget. These days it;s cheaper to do a NA-TT swap, reliable good power and no mess. Going NA-T is more investigating and cost more than a NA-TT swap. I went for the NA-T route but is i had to choose again i would go NA-TT. Quote Link to comment Share on other sites More sharing options...
