Hi gents just joined and would appreciate some advice. My car is a kit car called a GTM Libra, similar to an Elise.. weighs around 750kg and mine has a B18C6 (euro type R) DC2 engine in it.

One idea I have been toying with is turboing it, there's an abosulute mass of info out there regarding turbo B series Hondas and I'm quite confident it can be done reasonably cheap and with a good safe tune be able to churn out a reliable 300ish hp.


There's plenty of guys running low ish boost on fairly high compression, if I pop the 11:1 type R pistons and rods out I can easily fit B18C4 pistons on H beam rods without even removing the engine, that will net 9.8:1. The main difficulty will be fitting it all in such a tiny space...




I've thought about it a lot over the last few days and just found these turbo flange to V band adapters



I think that with 2 of these, I.e one on the manifold and one on the turbo, I can basically just pipe between them and mount the turbo wherever I want it... obviously the shorter the better. It would be a quick and easy way to replicate a sidewinder style exhaust where the turbo sits more over the box where there's more space. V clamps allow everything to be turned too which helps on something custom like this. Then wrap all the tubing and make some support brackets. Bit of a brain fart at the moment but I think it's do able, otherwise there's simply not enough space infront
Of the engine.


This is the normal kind of setup



Maybe a top mount would be better to keep some room below for the downpipe etc.
