TIV engine project

[70Turbobug]

So, instead it's going to be an original TIV housing, with 90mm full circle crank & 103mm LN Nickies with JE pistons. Other parts on the shelves are vanagon heads, completely redone with extra fins, Pauter rockers, TI lifters, ARP bolts, Riechert cooling and a GT76 turbo with 2 different housings, one 0.81 and one 1.15, unsure of which will be used.

Cam is going to be a JPM raptor and rods from FAT performance, neither of these are on the shelves at the moment.

Hi,
I agree with Wally and the others also.I wouldn´t go with a 90mm crank.You won´t have any advantage and you will have to take a lot of material out of the case.I save the money and keep the stock 71mm crank.Stock rods with ARP or Raceware bolts will do the job also.Again take a look at Wally´s build he´s pumping out 460hp reliably out of 2.2 Liters and 500hp is possible.He has a stock 66mm crank and rods.
If you do want more,then I wouldn´t go any higher than a 82mm crank and then either Moldex or Pauter.There´s just no need to go with a big crank.

So a stock crank is suitable for a Turbo application? **** I might just put my type 4 in like originally planned if that's the case.......

Yes, of course. I used a stock 2 ltr unit and got 220 hp, then with ratio rockers and still stock cam, stock pistons, (but with single HD springs) I got 270 hp...

Hermann from South Africa got 400 hp from his 2 ltr, like 10 years ago.
Of course, I could hardy believe it and certainly didn't understand it, but if you know tuning and turbo engines and what makes them tick, you can make any platform fast. Since the type 4 is a VERY strong engine to begin with and cools really well, it is an excellent platform to do so.
This is what I was trying to convey the other day, but got a 'good day to you sir' in the end...
