- Hilux with vp 5.0
Hi,
I fitted a standard vp 304 into my 97 Hilux Dualcab about 6 months ago and has been going well.
Last week, I pulled the motor out and have started on the come 383 stroker kit.
I have fitted the crank to the block and grinded out the bottom of the bores to allow the conrod bolts to clear.
Then I opened up the intake ports to suit the gasket, rounded off the pushrod lugs and general tidy up on the heads.
will be running standard intake, pushrods, rockers. the heads are in town now getting a 3 angle seat job and better springs.
The cam I have is a crow 4650 with 230/230 @ 50 and 113 duration with valve lift of .4983 intake and exhaust.
rollmaster timing chain kit.
standard injectors.
The exhaust and extractors are modified vp extractors and 4 into 1 collectors running to a y piece and then a 3 inch straight through system.
I am worried about it not running properly or not at all with the standard memcal/chip.
I am hoping to get this beast running and bolted in within the next 2 weeks but need some advise about the tuning... I don't want to run her lean and cook it.
I have an extra crow cam stage 3 chip that a mate gave me... would this one work better ?
or is there someone out there that has a 383 with similar mods to mine that could copy and download the program to one of my chips. (the standard one or the crow stage 3 one)
or would it just run ok as is.
could i just get some bigger injectors and run those with either of my 2 chips?
there is no dyno blokes around here that i know of that would be able to do it.
any advise would be great, thanks.
