Project "big Red" Anniversary...

[JamSkyRB20]

Car: 1991 Nissan Skyline GTS (Sedan)

Engine: Stock RB20DE

Suspension :Stock

Braking:Stock

Drivetrain: 5 Speed Manual Gearbox

Bought this car for $300,000JMD thats $4031.10AUD

I'll ask you all to bear with me as you can see our dollars dont worth shit here and these cars are very rare here so Ebay is my friend.

Skylines have been my long loved childhood car and I finally got to own this one exactly one year ago,I got it in relatively good condition as the previous owner was on the older side of life.

I'll tell you this I'm no pro on Skylines I love them to death and believe mi you have to literally love a skyline to own one in Jamaica caz it aint cheap parts place literally rape you when you go to buy parts for them they charge double the cost.

Any information that can enlighten my already shallow knowledge will be greatly appreciated.

This is a list of the setup I will be running bear in mind because of my lack of Budget some Items are included and excluded to cut cost.

RB25DET Stock internal(not sure if S1 or S2)

FMIC

440cc Side feed 06 Subaru Injectors

Greddy E management ultimate

Mines ECU

50 Shot of NOS(Maybe)

Custom CAI Aluminum Box behind the left Headlight

I am sure I'll have to include more to get 350WHP so help me with the others....

Here are some pics of the car and its phases.

The day i bought the car

1Week Later Rims added

Exhaust

Car was in a small accident little fender Bender so I changed the Nose cut and luckily got one with Foglamps gave the car a better look.

Hey buddy,

I'm seeing more and more Skylines, 300z's and silvias (not 240's) around the Islands.... Good stuff brethrin. I work on private superyachts, so I get to visit most of the Carib Islands once a year!

US Ebay will be your friend buddy... Also there is some GTRs and plenty of 240's with RB's in Florida (where I'm based during summer). I have Bahamian and Jamacan buddies in Florida with some awsome RB's/Skylines.

What kind of fuel will you be running your skyline on? and who is going to tune it? These will be the largest deciding factors when selecting parts.

As far as I'm aware, Jamacan fuel is relativly low octane but high in Benzene content... So I'd look at an aftermarket option turbo for 350whp. You will need some good tuning to make it last what ever way you go.

This is what I would do (assuming the engine and box are in good condition):

Leave the stock NA rb20de and box

Add an rb20/25det exhaust manifold (port matched)- $50

Precision turbo- billet comp wheel 5557 plain bearing- $1100

Dump pipe and exhaust- $350 (straight 3" mild steel with 1 muffler)

Clutch and machined flywheel- $500

N1 oil pump- $300 (yes they are that cheap US ebay- I bought 3 genuine pumps 3 months ago for $240usd each)

Cheap cooler kit- $300

rb20det cross over pipe (from cooler kit pipe work to throttle body)- $50

Matched 440cc injectors- $400

rb20det/rb25 air flow meter- $50

040 Bosch fuel pump (intank)- $150

ECU (what ever your tuner recomends)- $???

Plus:

New timing belt, tensioner and idler

fluids

filters

plugs

hoses

etc

R32 gtst calipers

R32 gtst rotors- redrilled for 4 bolt

Tein springs (1.5" drop)

Not too stiff struts/shock absorbers (Jamacan roads are generally fairly rough)

New bushes

200lb guard dog... too keep it safe. ha ha ha

PS where are you located on the Island? I might be that way next winter.

Cheers

Justin

I totally agree with you Justin but you mention something earlier in your post which is a fact the fuel we get here is cane juice shit, Jamaicas excuse for petrol and doing a High compression build in Jamaica is not my plan caz it'll probly detonate too quick I'd have to invest in methanol injection and a proper tuner..

I Live in Portmore jamaica thats near the City of Kingston.

200Lb Guard dog not really necessary caz no one steal these cars because of there rareness here.

If you come jamaica be sure to pm me prior to we can prolly link up in Portland with a few girls and thing .

I'd really like to make a link with a few your Jamaican friends though to get an understanding as to what they are running and my best shot at 350RWHP or even more.

Peace.

Yeah the exchange rate is crappy hence the reason the car is only looks so far.

If it's good sugar/cane based fuel then its going to be a good alcohol based fuel.... even better!!! If it has a large alcohol content, like ethanol/methanol mixed with benzine then a high comp boosted combo is peeerfect! We have E85 in Aus... it's made from cane- guys are running 12:1 compression and 20psi of boost with it.... good stuff.

Alcohol based fuel is less dense than regular oil based gas, so you will need to flow more of it to make the same hp.

If it's just crappy jungle juice, you might want to look into other methods of increasing efficiency/burn rate/energy/octane... If you can get access to Toulene (main component in paint thinner), you can add 1:7 mix into standard gas or if you can get Methanol, you can mix 1:6 into normal gas to help. What ever fuel you use when tuning- is the fuel you need to stay with.

The reason I suggested staying with the origional engine/box combo is the conversion to rb25 can become complex for the uninitiated... Wiring hassles and ecu tuneabiility, gearbox mounts, re-size tailshaft... etc Also the little high comp rb20 is easily capable of 350rwhp if tuned correctly... The key for high comp- turbo motors is to keep the boost as low as you can for the power you want. Eg get a slightly bigger turbo and run less boost for the same peak power figure... this will keep combustion pressures and compustion temperatures down.

The key to your power and reliability is going to be your access to good fuel and a good tune. Cooling is going to be your next issue-

You can allways drop the static compression by fitting a thicker head gasket... relativly easy fix.

My Jamacan friends all live in Florida... ha ha ha.

For ecu- have a look at a Nistune board. Any good tuner should be able to fitt and tune one. It will go into you origional ecu and make it fully tuneable.... no wiring issues.

What ever engine combo you go with, U WILL NEED TO RE-TUNE THE ECU to suit your conditions. The japanese tunes are rich up top, but they are designed for high octane japanese fuel- especially tuned ecu's like the MINES ecu's- they run lots of timing and dont have any saftey limmiters. If your fuel is alcohol based, the stock ecu is going to run dangerously lean with a little boost.

Justin I'm getting the Rb25 a bit cheap so hence its worth the try...and preping the RB20DE for boost is gonna cost me the price for an Rb20DET

I'll need injectors,intake/exhaust Manifolds,turbo,intercooler,and a few more I'm missing out....So I think its cheaper I purchase the 25DET and do a swap afterall It will be more reliable than boosting the 20DE.

What can I do about the MINES tuned ECU that I have to make it work regardless of the High octane gas its tuned on is so.

Will I be better off with a Greddy Emanagement and my RB20DE ECU rather than using the the Mines?

Is there a way to use some of the functions of the mines ECU like the raised rev limiter and then for fueling and timing I use the Greddy Emanagement?

350whp is 261rwkw...

Your not going to get 260rwkw out of a standard rb25 turbo... and you shouldn't run the stock injectors that hard either. And that's with 98ron fuel in Australia with a good/great tune and ecu.

Considering yout environment and fuel, your not going get the most from a stock set up.

To make your 350whp target, you are going to need: Turbo, injectors, fuel pump, bigger intercooler, exhaust, ecu/tune.

Plus the 25 swap you will also need:

- Modified tailshaft

- Modified wiring loom

- Gearbox sender drive mods

- Gearbox mounts

- Intercooler and exhaust mods (rb25 sits higher)

- Fuel pump (rb20de pump isn't going to cut it)

- etc etc

You might get away with 300whp from a stock rb25 turbo, injectors and ecu with somthing like an SAFC.... the turbo won't last long either way.

RE: the mines ecu... I'd loose it. Do you have access to a dyno and competant tuner?

If you do, buy a nistune board www.nistune.com it will be cheaper than a mines ecu/greddy e-mange and you will end up with a much better tune. You can fitt it to your rb20de ecu... you cant fitt one the the rb25det ecu.

Ok so after a year and some I'm back with some amount of good news re this project....I didnt get to turbo my RB20de as it got scared and left me on the highway checks revealed that a bad oil pump was the culprit so I had to get me a RB20det, I have since installed a walbro 255lph intank pump and has been having alot of fun.

I didnt upgrade my exhaust system and that the back pressure from my little 2.5" crush bent pipe blew off the ceramic back wheel as well as the front seal of the turbo has started leaking out all my expensive AMSOIL. i took the decision to park the car and take it slowly as my work takes me 400miles weekly. I now take the bus to work but I have bought and installed a new FMIC KIT the one to bolt right up on the r32. I have installed all the necessary gauges. My plans are to upgrade the turbo to a T3/T4 50front and .63back from eBay as budget kinda tight here.

I want to achieve 350rwhp max daily driven safely.

Need the following stuff:-

440cc injectors

Coilover suspension ( I have 2 KYG AGX for the back but cant find the front to match)

Tial 38mm Wastegate

HKS SSQ BOV

I have everything else that will be needed all and any suggestion will be welcome guys I really need the help. And by BTW I'm from Jamaica.
