Hoping some knowledgeable PH'ers on this forum could help out a friend of mine who fancies upgrading his Nissan. Below is his question. Thanks
------------------------------

Nissan 200sx touring. Want to get to either 240bhp or 270bhp.

240bhp conversion done via K&N filter, turbo boost increase to 15psi + cold spark plugs, new Mongoose exhaust. price = £700.00 parts + £235 labour, all inc VAT.

270bhp conversion is as above but with new intercooler that is 6x larger than old one and has potential to get engine up to +400bhp. Turbo boost raised to 17psi. price = £1000.00 parts + £140 labour, all inc VAT.

Question: Can I get to 270bhp with a cheaper intercooler upgrade?? The 6x one seems a bit of an overkill for a 270bhp system.

There are loads of mods you can do to a 200sx. Get on the message boards at www.sxoc.com and ask on there (SX Owners Club - invaluable).

The intercooler is that much bigger (6x or whatever) as the standard one is small and hidden in the wing, and I am guessing the replacement he is looking at is a massive front mounted job. You can get biggerfatter wing mounted intercoolers which should be a cheaper option than a frount mounted. You can also decat the front down pipe which leaves the main CAT still in for MOT day.

As a warning, there is much debate over using wetoil filters (such as K&N or HKS) as it is thought that the oil can get onto the MAF sensor (air flow sensor) and send the readings out. A lot of folks believe using dry filters is the best option ... I couldn't possibly comment (BETTER SAFE THAN SORRY!!!!)

Great stuff, thanks. I'll point him to the link. I'll also let you know how he gets on - but think he's still at chin scratching stage so don't hold breath.

Cheers

Just make sure you check your fuelling if you up the boost. Don't want things to melt and go bang...

They have 197bhp on paper as standard.

Intercooler first, then decat & intake, go gently with the boost as fuelling is an issue.

Never up the boost without an intercooler suitably sized, or your just pumping overheated & expanded air in = detonation & dead engines fairly rapidly.

if he wants big power then forget any wing I/C and go for the proper FMIC.

Apexi do the best air filter for filtration and power increase apparently
