I made the decisions with regards to the internals I was originally going to go with a 2litre engine I had already bought the PAR rods because of my plans at the time were to go for a HKS 3037 turbo but decided against that because of the cost of them and the wastegate costs for a jap make external wastegate the prices were ridiculous and I didn't know much about the TIAL and the US wastegates at the time.So in the end decided to have a rethink sold the PAR rods and thought if I would to work out how much the rods pistons and if there were any damage to the crank I could of paid a bit more for a solid bullet proof bottom end that could rev to 8500rpm no probs this was at the time when RC Devs were having there Demo car stroker ready for fitting and they mentioned they were sorting out a 2.3 kit to a v simalar spec to the EVO one.
With regards to the turbo choice I looked through lots of choices wanted a turbo that could produce 600bhp with as little lag as poss easier said than done another reason for the stroker kit
so the search began through google mainly checking out different sites with similar sized engines to ours e.g scoobies,cossie,EVOs looking at Rolling road printouts with graphs boost settings etc and I made my choice after a couple of months of looking.Then there was the choice of eternal astegate to look at was quite limited at first because there was no way I was paying £500+ for a Greddyor HKS one.So this limited me to a TIAL,Turbosmart or a TurboXS one,after reading some articles about porsche 911 race cars using the TIAL wastegates on a lot of different teams this got me set on the TIAL and looking through the online shops from the US the prices were close to half of the Jap ones.After having a discussion with one of the big helps sourcing and deciding on parts Nikko and I looked at what size would be the best after also looking through various forums at similar setups.
Then I can go on and on about cams,intercoolers,throttlebodies etc.In the main I wouldn't bother asking a tuner about what parts to use because they will always say use the ones they do for example a certain well known tuner would use one company for most parts because they get them cheaper and make the extra profit on top as well as selling you the part doesn't mean to say the part you are buying is the best for that application.If a tuner is gonna build the engineI would consult them about headgasket thickness,piston compression and also for mapping I would use the ECU of there choice at the end of the day it is down to the person doing the mapping with the ECU they are familiar with you can have the best ECU in the world but if the mapper can't use it what is the point.
If there is anyone still reading this well done waffling over my fingers are aching hope this helps you a bit
