DanTheB18Man Posted June 20, 2016 Share Posted June 20, 2016 (edited) Hello all! After a long time thinking of what build i want to go with im leaning towards N/A but i have a couple of questions to ask:- 1. Is there any definite mods i should do that helps power 2. Is there a different head option that would help? 3. What kind of clutch would i need for a 220bhp build? stage2? 4. I have big fuel injectors, will i benefit from these on n/a? PS. running a b18c4 with 2.5" exhaust and whale p***s induction. Thanks!! Edited June 20, 2016 by DanTheB18Man Quote Link to comment Share on other sites More sharing options...
JK1245 Posted June 21, 2016 Share Posted June 21, 2016 A full 2.5" system is a good start already, especially paired with a good Toda style 2.5" manifold. Also on a C4, a replacement intake manifold is a must for peak hp. 220hp from a C4 is going to be a bit of a push, but if you are willing to go pretty hardcore it can be done. Another thing you could look at is building a B20 bottom end and running your C4 head on it. A built B20 with forged rods/pistons and bolt ons will see 220+hp on a C4 head, I've priced it up recently and you're looking at around £1500-2000 for it to be reliable and have springs/retainers capable of revving to 9K.

Yeah i heard that but the whale induction sounds immense! Quote Link to comment Share on other sites More sharing options...
DanTheB18Man Posted June 21, 2016 Author Share Posted June 21, 2016 Is a b16 head not an upgrade? Quote Link to comment Share on other sites More sharing options...

KiNK43 Posted June 21, 2016 Share Posted June 21, 2016 Without going bonkers. 195ish is about the limit. Any more your looking at pretty steep build. Raising compression. Various degrees of headwork. Any one who claims to have 220hp without serious mods has been on a very generous maybe manipulated dyno. 1 Quote Link to comment Share on other sites More sharing options...
DanTheB18Man Posted June 21, 2016 Author Share Posted June 21, 2016 ahh right! cheers thats gave me something to think about :/ Quote Link to comment Share on other sites More sharing options...
JK1245 Posted June 21, 2016 Share Posted June 21, 2016 Regarding the B16 head, it actually drops the CR when bolted on a C4 block and makes less power. If I was to go back and re-do my build I'd stop f***ying around and just buy a B18C and have 198hp from the off. In the meantime, an S80 makes a maaaaasive difference to how responsive the C4 feels.

dr_broon Posted June 22, 2016 Share Posted June 22, 2016 Yeah, the gearbox is where the best bang for buck is performance wise. I've got the final drive from an s80 in my box and the difference is great. Great way to free the potential of the engine. Have a look on team mfactory website for more information on benefits of better gear ratios. Quote Link to comment Share on other sites More sharing options...
