I Would Sugest That U Use An Inled Manifold From A 1993 Nissan Sunny Gti-r.they Use Throtle Bodies As Standard And They Can Flow Up To 800bhp Easaly.u Will Need Mashining And Port Maching But Its Well Worth It And They Sound Amazing!i Dont Know The Prices Of These Parts In The Uk But I Bought Mine For 600 Euros And It Cost Me Another 400 To Fit Them So They Are Much Cheaper Than Swidish Inlets And They Are Much More Responcive Than Standard Idems.i,ve Measured Mine And Im Now Running 560whp @1.8bar (with Some Other Parts I Have Added Including A Gt30 And Motec)
