I'd do the cams as well if your gonna go all out. Then at least with some good injectors, z32, decent turbo you should break the 400bhp (fly) mark.
***RB20DET engine rebuild question***
Hi guys,
I've got a R32 GTST with an RB20DET in it.
The head gasket appears to be on its way out so I am looking at a rebuild seen as I have to dig down that far into the engine.
I have the following parts bought for this round of work-
Conceptua head gasket kit- inlet, manifold, rocker covers, head gaskets
Conceptua head to manifold gasket
Conceptua manifold to turbo gasket
Conceptua turbo to turbo elbow gasket
Conceptua decat gaskets
Conceptua manifold studs
Conceptua Fuel filter
Conceptua Oil filter
Exedy organic clutch
A new oil pump
Japspeed Oil cooler and filter relocation kit
HKS oil temp gauge
HKS coolant temp gauge
Do-luck steel braided brake lines
I'll be ordering a fmic from japspeed tomorrow.
I've been talking to a mechanic already about carrying out this work and he has said he will arrange for new shells, bearings etc in the bottom and a clean and hone from a local engineering shop.
I'm looking for peoples thoughts on this rebuild please-
What other parts should I buy?
What other work should I have done while the engine is out?
What parts should I upgrade now instead of later on?
You get the picture- if you have been there already or have useful knowledge I'd really appreciate you sharing it.
ps.
The car has the following work down so far-
Japspeed alloy radiator
Japspeed engine torque damper
Japspeed rear strut brace
Japspeed turbo elbow
Japspeed down pipe
Japspeed decat
Tannabe cat back system
Conceptua BYCAS system
K&N air filter
255lph fuel pump
Apexi RSM (wired in)
Apexi AVCR (wired in but not set up)
Apexi SAFC (just sitting there)
R33 GTR Brembo calipers and discs

Sorry my bad probably not 400 maybe 380 but should be able to push the torque more. You'd need other new internals to break 400, misread what you said you've got
Right, what type of money do cams cost and where supplies them?
Not had a look in a while matey but they are some quite serious money from memory. I'd probably ask a tuner. Don't wanna give you price then find i'm missing a vital component that's £££££££
As an example, here's where you start http://www.nengun.com/jun/high-lift-camshafts-nissan-rb20det I wouldn't have a clue which duration and lift is suitable, or which are the other parts needed to go with it. Hence why I say ask a tuner.

So they are, well spotted 
Think he should go all out and get a stroker kit RB22 or Rb24 anyone!

No point in going for the stroker kit as there are RB25's going for cheaper than it would cost to buy all the bits I need for a RB22.
I like my RB20 and won't to tune it rather than buy a bigger engine.
I hadn't really thought about cams, I was thinking my next stage of work would be a-
bigger turbo
bigger injectors
F-CON ecu
and a really good mapping.

To be honest mate that is the stage im headed for then i'm get the cams done. It's just you said you've got the engine apart so thought you might as well. Was just joking about the stroker kit. By the sounds of it your like me, wanna tune this RB20 as much as i can. Only differance is when it goes pop i'm gonna track down an RB30 to throw in there
I've been chatting with the guys over on skylineaustralia.com and they have got big power from the RB20 so I'll be sticking with mine for a while yet.
If I was to buy and fit the cams now, I think I would need to get the car mapped which means buying the F-CON now which I was not planning on doing yet.
Its all about the budget- I've got a second black R32 which I want to do some work to for using on track so I can't really afford to go and put all my money into my white R32 at the moment but I'm really interested to find out what I can do to my RB20 to get more power and how much it will cost and what order I need to do the work in.....

You don't need cams when your running standard turbo etc.
With a good map 400hp can be reached on standard cams so they would come after turbo/injectors/ecu etc.

al not being funny but you have the full exhaust, and your intake, you should ideally be looking at a FMIC and ECU and a good map to get the most out of what you havem youll see a significant increse with a decent map as it is, as for turbos injectors etc they will all require a map, apart from same size piston kit and race bearing while its apart theres nothing really that can be done to the car that wont require a map either way,
so IMO valuable of not get the problems sorted put your money into the ECU and map for now till you feel flush enough to go all out on it, as you said you have the black one there too, maybe sell that on and go nuts on the white one, or just set up the white one right and put the rest into the black one. also youll be able to free up some cash by selling the SAFC and RSM if you go for the ECU now too,

Cheers Paul, its information like that, that I crave.You don't need cams when your running standard turbo etc.

I need to figure out what parts get added and in what order.
How far certain parts can be taken before they go pop.
What each modification or stage costs.
The FMIC will be over from Japspeed in the next while.al not being funny but you have the full exhaust, and your intake, you should ideally be looking at a FMIC and ECU and a good map to get the most out of what you havem youll see a significant increse with a decent map as it is, as for turbos injectors etc they will all require a map, apart from same size piston kit and race bearing while its apart theres nothing really that can be done to the car that wont require a map either way,

Chris at Conceptua has sorted out most of the parts I need and Paul (Nissan Doctor) has been advising me in the art of skyline tuning :bigthumb:
I'm trying to figure out what each modification will cost me and in what order they need to be done relative to each other.
Selling the Apexi RSM and SAFC would only raise 200-300 euro euro and the F-CON ecu costs about 1200euro and an additional chunk of money each time I add anything else.
So I'm trying to plan a route that balances my desire for more power with what I am willing to spend, while been realistic, so as to not **** with other aspects of my life.
After all, there is no point in having a fast car if you can't pay the rent or afford the nice things in life.
true but theres no point in chasing the power and trying to tune the car on an safc, to map your car properly you NEED A MAPPABLE ECU be it an fcon power fc egrddy emanage you need something that does more than air fuel ratio.The FMIC will be over from Japspeed in the next while.

Looks like tubrosteen had his post removed for disobeying the rules.....
Very true, the only reason I said cams was as his engine is all apart didn't realise there was a tight budget here. 400 bhp is at the very limit of Rb20 internals though, 380 would be a far safer figure. And yes in a normal situation turbo/injectors/ecu (like im doing) would come first.You don't need cams when your running standard turbo etc.
With a good map 400hp can be reached on standard cams so they would come after turbo/injectors/ecu etc.
As said another ECU option will be needed as well.
With a really good map and a fresh engine a standard RB20 can run up to 450hp safely.
At that level a precise and knowledgeable map is paramount but it can be done.
My RB20 track engine will be running over 400hp on e85 and standard internals.

It might well do, but i can't see it lasting too long. Good luck with that though mate.
