RB 30/25 TORQUE MONSTER   '' walkthrough''

After alot of quoting and conversations with customers about the internals of the 'monster' we have decided to give a step by step run down of the combo in this section . The power output of this combo totally is turbo choice related. We like to call this combo a safe 300rwkw setup and 7500rpm max..  Over this rpm we recommend an oil pump upgrade and other upgrades are available upwards of that power level. The combo is the most value for dollar spent . Please take time to read through the RBtech tips section for further ideas.

The build starts with chemical cleaning and cracktesting of all parts .We then bore the block on our custom made jig to ensure the bores are straight with the crank main tunnels. The deck is then done on the same jig so all is true to the piston crown,after this we hone the bores with a custom made honeplate to our own tried and proven hone finish. One lesson i have learnt over the years is its not the fancy machine you have at hand but the knowledge to give the correct hone finish for the ring set type chosen!!!. The crank has one of our collars fitted see RBtech tips section for correct fitting. Crank is clearanced, oil holes screwed, micropolished and all internals are balanced on our CEMB balance machine. ACL comp bearings are fitted using our custom clearances and short block is complete.

The build comes with a new waterpump, tensioners and GATES belt, with tensioner relocation. The build uses a modded rb25 oil pump as said rated to 7500rpm max. We fit custom forged pistons with our favorite ringset. Use of an MLSR steel head gasket along with our micro finished deck surfaces ensures an accurate sealing surface. The head is given a mild port job with multi angle seat job and the as usual meticulous assembly. The build uses stock camshafts and springs as per the 7500rpm limit once again. Our race sump is fitted as is stock rods with arp bolts and the normal resizing and bushing. Oil restrictors  and genuine nissan gaskets used. PRICE $6500 .

Recommendations and upgrades for 300rwkw plus and 7500rpm plus     as follows

1. h beam rods $699 extra

2. ROSS race  harmonic $595

3. Tomei oil pump $2200  depending on yen at time of purchase.

This particular customer chose to use our ROSS metal jacket balancer  and oil drain backs and catch can for track use.

The ''monster'' is a custom built engine to youre requirements with turn around time approx 4 weeks.  It is without a doubt the most value for dollar and with our run in and tune procedures will provide thousands of hours of tyre shredding fun.

BUDJET  RB26 GTR  '' WALKTHROUGH''

After many emails and customers questions regarding the  ''budjet'' rb26 GTR build $6500 we have decided to run a detailed walkthrough of the combo which we can direct customers to and what they get for the cost they can see.

Like all of our other engine combos these are  a build youre own basis. We can buy in a core engine and build while you drive then exchange once built if required.

The build starts with full chemical cleaning, cracktesting and inspection of all parts. The block is bored and decked with deck finish suitable for MLSR 4 layer head gasket used. The block is honed using our SUNNEN hone and custom bore finish.

ACL competition bearings are used and crankshaft is ground and micropolished to our custom bearing clearances. Alot of time is put into getting the bearing clearances to our specs. We regrub screw the oil holes in crankshaft and fit our crank collar if R32.

Custom JE or Arias forged pistons are used with TOTAL SEAL rings. The rods get a new set of ARP bolts and are resized both ends then all internals are balanced.

The cylinder head recieves a complete service including  chemical clean, 3 angle valvejob, new seals and reface with tappett readjustment. All genuine nissan gaskets are used so after the build you are supplied with the leftover gaskets as in manifold gaskets and all turbo gaskets included. New core plugs are fitted, genuine nissan sealants and a fresh black paintjob.

The timing components include a GATES race timing belt and all new tensioners and waterpump. The build price does not include removal and redressing of accessories just a basic sump to cover build. Turn around time approx 4 weeks .This combo is rated to 7500rpm and 300rwkw. Further recommended upgrades for increased power levels are as follows......

ADD................

1. h beam rods $699

2. ROSS harmonic balancer $699

3. Tomei oil pump $2200 depending on yen conversion at the time  .   FOR 7500 RPM ONWARDS .....

4.HKS ,TOMEI or our custom cams $1200 pair

5. spring upgrade to suit $699

6. hi vol alloy RACE sump  $999. '' OR'' TOMEI style trap door sump tray $400.

No secrets here this combo will go around 250rwkw with stock GTR turbo,s   and up to 290 rwkw with upgraded turbo chargers  after this power level we recommend our upgrades as described above..................................................................................

408 chrysler STROKER twin turbo BUILDUP

Starting with a select picked factory 70,s vintage 360 block, we started work on our build

which is destined for an early chrysler with two turbo chargers 'OUCH'.....

Knowing all well the ammount of stress on the internal parts we have been selective on the

parts used. The block recieving chemical cleaning, sonic bore checking, square decked, and

bored and honed to 30thou oversize. Durabond seamless cam bearings are fitted to ensure

the custom crane solid roller cam spins with maximum bearing support. After fitting the

Program Engineering 4 bolt main caps the tunnels were machined along with the Scat crank-

shaft and speedpro h series main bearings. To handle the push on the Scat h beam rods we

chose to use the hi performance King series bearings. A target 9:1 comp ratio was built in

to the KB forged pistons. Sealing it all up we used ever relible Hastings race ringset.

All of the chosen parts are an array of the best quality using Crane gold shaft rockers,a new

timing cover, Milodon oil pan, Rollmaster gearset and brass welch plug kit. We balanced the

entire assembly using a Proffessional products balancer and B&M sfi approved flexplate.

Internally balancing it to enable easy convertor choice and manufacture.

Quiet a few days were spent hand porting the Edelbrock alloy heads netting 300 cfm @600

lift. Using Manley 2.055 and 1.65 valves along with Crane triple springs,retainers and locks.

An interesting feature with the KB forged pistons are that they have a raised quench pad on

the piston crown which we have sat out the deck and squeezes into a carefully machined

reciever pocket which will provide an efficient quench pad squish area. T he end result being

to run less timing and still produce an efficient burn and ease the pressure from the engine

internals. Felpro oring head gaskets and ARP studs throughout keep all the squeeze inside.

All parts can be found throughout the website and if requiring one of these combos they

are $23,000. We will let you know the dyno results and pics of the car once completed .
