Re: Supercharged 2GR SW20 Project - Bosch Top Feed 2000cc Injectors

Post by lasersooby »

Decided to add meth injection to the intake air before the air went through the supercharger and through the plate w2a intercooler.

Purchased 2 x 2000cc Bosch Top Feed Injectors for the job. The plan is that we will set everything up to run but the meth injection will be sorted after the engine is up and running but before we get it on to the dyno. The controller for these injectors will be through the UniChip piggyback ECU:

Re: Supercharged 2GR SW20 Project - Few Images of Engine from CSL Race Engines

Post by lasersooby »

Received a few images of my engine block and parts from CSL Race Engines that we agreed on getting done.

Pretty excited and the following was done to the engine block and heads:

1. Block bored out to suit 94.25mm forged pistons that were purchased off MWR
2. Rotating assembly was fully balanced
3. Crankshaft was lightened and shaped
4. Machine deck block faces
5. Make block spacers
6. Machine cylinder head faces
7. Machine valve seats - custom 3D cutters
8. Machine valve front & back faces
9. Machine top valves inlet - 0.25mm, exhaust 0.4mm
10. Dummy assembly to check deck height
11. Head already been ported and polished, port matched to exhaust as well as lower intake manifold
12. Lower intake manifold ported and polished for maximum flow from the supercharger
13. All parts were acid dipped then vapor blasted to clean prior to the work being carried out

Just a few more pictures of the rotating parts getting fully balanced. Do not worry, the green paint on the flywheel will be removed before it gets installed:

Different angles of the block, needs a heap of cleaning before we start the assembly process. Everything on the engine has been vapour blasted:

Re: Supercharged 2GR SW20 Project - Selecting Main Bearings

Post by lasersooby »

Interesting conversation with the Manawatu Toyota guys, especially Mark Ireland who sorted out the main bearings for the engine build.

To pick the bearing, we had to get the bearing clearances that were already stamped on the underside of block and also the front of the crank. See images below:

Based off the readings off here, this is the Table to use to determine the correct main bearings for the engine:

Re: Supercharged 2GR SW20 Project - Carbon Fibre Vented Bonnet

Post by lasersooby »

Pulled the pin and ordered a carbon fibre vented bonnet for the project. Buying one on its own was going to cost nearly NZ$2,000. Thankfully a number of friends (actually 3), stepped up to order with me and we have managed to get a really good price on this set, the savings all come from the shipping.

Re: Supercharged 2GR SW20 Project - Extended Lock & Key_Boot Lock

Post by lasersooby »

It has been a while since I posted, turns in life has a funny way of getting into the mix which stops us from doing things that we enjoy.

Anyhow, I purchased Extended Boot Lock Key Set from MR2 Heaven with a few other parts. Richard was amazing to deal with and nothing was a problem, he even organized cheaper shipping options for me which saved a bit of coin. The link for this part is:

https://mr2heaven.com/collections/exter ... i-94-locks

Great quality part and fits without any issues (have to now install the centre panel once it is painted:

Re: Supercharged 2GR SW20 Project - Preparation to Assemble Engine

Post by lasersooby »

Had to take time out to clear my head after my mum's death on Friday in Melbourne and what better way to do this than to start preparing the engine assembly. The first step was buy a new engine stand as well as an engine lifter from Supercheap (could not afford Ripco prices :P :P :P ).
Most of the parts laid and will start on this next week once I return from Melbourne.
