Thread: SR16VE + RR 2.0 crank and rods??

right im in the uk and have managed to get an SR16VE for dirt cheap.. i want to know if this will work.. i want to stroke it to 2.0 can i use the crank and rods from a uk Almera GTI SR20DE RR with N1 pistons and cams? what compression ration will it end up with? I will hopefully be using the SR16VE ecu to rev out to 8300RPM and have the cams switching at 5K roughly (MSS).. will i need bigger injectors with the increased cappacity? i want around 200WHP will it make that with an SS header and possibly an e-manage as im on a really tight budget if it will make that without the e-manage just on the standard ECU ill be happy..

13.0 to 1 compression with N1 SR16VE Pistons, 13.5 to 1 with SR16VE pistons.

The SR16VE ECU will not work right as the timing will be way off.

You will not need bigger injs.

The crank and rods from a UK Almera are identical to a 2L VE crank and rods.

you will make 200 WHP with a SS header

If you are on a tight budjet why run a emanage, Just get a Calum ECU for $110. Shipping to you in the UK would be about $50 for a total of $160. Thats alot cheaper than an Emanage.

SR16VE ECU at $100 US + E Manage at $360 US = $460 US

Vs

SR20DE ECU $50 US + Calum ECU charge $110 US+ Shipping to UK $50 = $210 US

You can go big dog with

SR20DE ECU $50 US + Calum Realtime Programable ECU $350 US + Shipping to UK $50 US = $450 US

any way i can bring the compresion down to be able to use the normal SR16VE ECU for now? what if i put standard flat top SR20DE pistons in there from the uk almera i want to get the engine in and running really.. without having it silly high compression and having to run high octane as its really expencive over here..

SR16VE with full 2.0 bottom end including pistons with an SR16VE ECU N1 cams and a good exhaust/ intake would be able to get 200WHP?

many thanks for the help andreas

With straight flat tops the valves will hit the pistons. You will need to have valve notches cut into the piston so this does not happen. 11.5 to 1 with a straigh flat top and 11.3 to 1 with valve notches cut.

bugger this is what i was worried about with putting the 2.0 crank and rods in it will run expencive as i just wanted to keep the SR16VE ecu but up it to a 2.0 i take it then its the heads that add the compresion of the SR16 what if i added SR20VE pistons would that clear and have lower compression?

the head does not add compression.

The size increase of the motor is what adds compression. The heads are the same on a SR20VE and SR16VE.

these http://www.gspec.com/p-4958-piston-20-vvl-20v.aspx they look like flat tops with valve notches

sorry thought the head was shaved down on the SR16.. anyway looks like i need to get saving as this looks like it wont just be a simple this goes to this and use this

First off that is not a flat top piston you can clearly see the dish in it.

That is a 20V piston from a P12 SR20VE 20V that gives 11 to 1 compression. As stated this is a factory piston that has valve notches from the factory.
