Rb25det Upgrade And Problem

[muzziak]

Hey guys, I have a 1996 R33 skyline GTS-T, recently bought it and thinking of adding some more power, current mods to my knowledge are ;

- splitfire coil packs

- kls power spirit turbo

-fmic and intake (Z32 afm and all the rest)

-high flow cat and full exhaust system

-walbro 500hp fuel pump

-current spark plugs are platinum PFR7B (problem possibly)

-dump pipe

Etc etc etc, basically all the basics

Last tune was in 2013 and was 220kW, I've misplaced the paper though.

So here's my question, what could I do to possibly get it to 250kW, I was thinking cams or ?

Also, at high revs, around 5500-7000 the car starts to spit and misfire, but the plugs were changed in 2013 so I don't know what it could be. I'm aware there's topics on these but I couldn't really gather much from them.

Thanks for your help guys.

No mention of ECU. No mention of knowledge of what the fuel pressure is when running full load + revs. Boost? Checked for intake tract leaks? etc.

Plugs haven't been changed in 2 years...and the car is misfiring...

Where oh where would I start??

Nitrous should do it

And more BOOST

power fc, boost controller Is set to 18 but hits about 15-16 psi. Car obviously needs a tune but want to upgrade first before tuning.

Relatively new to the site. Sorry

The first thing I would do is piss off the eBay turbo.

Yeah i vote for checking your sparkplugs/coilpacks and getting a better turbo.. or take it to a well known tuner in your state/location and they will be able to see what your car is doing and most likely be able to help diagnose any/all problems

No need for cams. Send in your stock turbo to us get that high flowed. That will make over 250rwkws and super responsive.

[muzziak]

Yeah definitely want to get it tuned, cause I know it needs one. Just thought I'd chuck in an upgrade before doing so. A new turbo is slightly out of my price range atm to be honest, any other idea you guys may have ? Thanks heaps for your help

[Ben C34]

What's in your price range? Just a tune?

How will the car make more power? was it already tuned?

[Ben C34]

And you suggested cams, they cost more than a turbo installed ...... Or did you plan on putting them in yourself? You don't seemed clued up enough to do that.......

Get a price from Hypergear for the turbo and start saving. In the meantime replace the plugs and clean and check the coils.

[muzziak]

Probably around $1000-$2000, the car was tuned in 2012 and hasn't been since. Ah sorry I actually thought cams would be the cheaper alternative

[muzziak]

Yeah this weekend I'll replace the plugs and clean coils, check gapping etc etc and see how it goes

[DoseVader]

A Hypergear highflow is $850 and will shit all over your china turbo

[muzziak]

I'll look into that thanks, turbo was put in prior to buying the car unfortunately

[Artic Choc]

maybe send your ch ina turbo to stao he may be able to make something decent out of it, hypergears service is 2nd to none Either way hel be more then whilling to find a turbo for your goals

[muzziak]

How exactly would I get in contact with Stao ? Found a number but that's from 2009
