Stroker Kit Decisions

[bigmikespec]

have a look at proengines RB30 packages. If I was doing a 30, I would be getting it from greg no doubt. he's built a number of engines for friends and people that I have referred to him and they have all been happy. he's a smart guy and charges fair rates for his standard of work. considering that for about $8000 you can have a built 30 bottom end complete with his own sump adapter ready to go it's not bad value. I would then look at one of those endyn or bullet CNC heads (go the OS valves on the 30 for sure). get that sent to greg too, decide on cams, add some valve springs etc and get him to bolt the whole thing together. around $12-$14K would see you with a complete top notch forged, 2630 with a sweet head. bolt on a set of 2530s and enjoy 400awkw and very decent response.

a top notch 26 will work out about the same price.

a top notch HKS or tomei 2.8 about the same price too.

$15,000 is what it will realistically cost to get a top level GTR engine no matter what the capacity.

This post and the one that preceeded it should be read by anyone considering in going from standard bore/stroke to a stroker kit of some sort. Great info and explanation.

Don't know if this idea is a silly one but .

Is there any oxygen in having a spacer plate made up fitted and bore the whole lot for thin walled liners ?

If the idea flew you could keep your block number and retain its piston oil squirters , do the usual with an RB30 crank and rods and have your three liters ?

Thoughts , cheers A .

sounds pretty much like a os giken rb30 set up

dont waste your money on stroker kits they are stupid expensive and the rb30 is better way to go unless you go the os giken 3L kit. I wish i went a RIPS rb30 and saved the money back when i built my jun 2.7l stroker motor. The stroker kit (just crank, rods and pistons) is worth as much as a complete built bottom end from RIPS which is complete and ready to go from what i can tell and is proven to hold over 1200hp.

for your goals i would save alot of money and have a better setup using a rb30 and a t04z, it will be perfect for 430awkw and have decent response too.

so your saying i should have charged you 10k for my rb30e

Thanks Richard and others for your advise. I guess I will have to get the old excel spread sheet out and start doing shopping lists for setups in each class and then start weighing up pros and cons.

I guess what makes it hard to choose a direction is when a reputable person who knows their stuff says one one and then an equal has taken a completely different stance which makes you kinda question which one would be more applicable.

I'm trying to stick to facts and see results black and white, but that in itself is hard. After having looked at all the dyno results there's not alot of 2.8L that stand out yet Richard your exp in Japanese says other wise plus you have the added bonus of haven been in a RB30/26 to compare.

Then the notion of having a built RB26 with the right head components etc purpose built for response sounds excellent.

Its hard to pick a line atm and go for it.

Any details or build thread on that GT block 26 circuit car?

Cheers
