I’ve been through 2 4l60e with moderate driving, so I don’t like my chances. Say if it’s a 50/50 chance of holding up or not, I’m not really interested in spending 11k+ on forced induction and have to stress about if it’s going home on a tow truck or not. If I got boost I can 100% assure you I’d...

Very fair point mate. I’ve been quoted $3200 to swap heads for a set of Higgins, labour, transfer springs, rods ect and dyno tune. So drive in drive out. I’d love to sidemount but my 4l60e gearbox won’t allow for it unfortunately :(

That makes sense. I’m very limited with what I can shave off the heads as my VCM13 cam specs might create themselves their own fly cuts in the piston heads. Ive read 6.0L & 6.2L heads are great from factory where as the LS1 heads are absolutely horrible for flow rate, hence why people say their...

Honestly mate. I think everyone’s convinced me enough. I’m going to wait a little while before I boost my car. I’ll get the engine and gearbox sorted first just to be safe. At this stage I’m planning on adding some Higgins heads as the standard ls1 heads aren’t ideal and apparently a great upgrade.

Hey guys. Just wondering if anyone has previously had a cam kit done to their ls1 and decided to get ported and polished heads added at a later date? Would love to know first hand experiences regarding their thoughts on the upgrade? Worth it? Are Fast manifolds worth it on a big cam & head combo?

Good to hear!

Yep, I’ve read your build diary extensively. your 383 stroker alone would of busted your 4l60e let alone adding a 2300 blower to add to the equation. And also, a bloke who commented on your post has a built 4l60e and a 2300 running on low boost and hasn’t had a drama yet. So I see a slight bit...

Hey guys. Would love to know who’s running boost while retaining a built 4l60e? I’ve currently had my 4 speed rebuilt & strengthened a few months ago and only just decided to buy a 2300 harrop supercharger for my ls1 I completely understand that the gearbox’s are trash so I don’t really need to...

How is your gearbox holding with its current mods?

Sucks about the constant gearbox issues :( do you think being blown & a 383 stroker combo is what played a huge factor for its constant breaking or would just supercharging a stock ci LS1 with a built 4l60e never work? I’m currently in the process of getting a harrop 2300 for my LS1. Already...

Hey guys! Hope everyone’s well. First off I’m not trying to start a war or argument of any sort in regards of asking for some advice about a boost application for my 5.7L ls1. I’m 100% sold on wanting to supercharge my car, but the question is do I go sidemount or top mount? I understand top...

I haven’t checked levels or I’m unsure of what oils in it. It’s a 400rwkw rated stage 2 box as the car was originally going to be set up for a 150 shot at Calder but the previous owner had to sell due to certain circumstances. Although the box itself feels and shifts fine I believe. It does have...

I had it retuned because the shifts points in the box were way out of whack for my liking. It was originally tuned back in 2017 so I thought it would be due for a fresh tune anyways. Which back then apparently made 250rwkw on another dyno. I then got it retuned which made the car a lot nicer to...

Yep, I know plenty of people with the exact same mods in a manual trans tho. sitting anywhere from 280-310rwkw. I mean I don’t understand how a highstall robs power?

I had the dyno sheet which I’ve unfortunately misplaced. I did notice the the torque curve shot up hard and quick but as the car revved out the torque curve was actually decreasing over the run. Could that be because of the stall converter maybe?

My 4 speed already have a stage 2 shift kit. Love it btw!

Yeah that’s fair. Didn’t think about the optioned r8 situation. I still would of thought the 5.7L with those mods should of packed a lot harder punch mid roll.

Hey guys, its probably been posted here before but cant really seem to find anything that thoroughly answers my question. Anyways i've purchased a 5.7L VY R8 with; 1-7/8 4-1 Pacemaker headers Auspac 2.5" catback CNC Ported heads 200 cell cats Ramjet OTR GM Motorsport Turbo killer cam 237/243...

@Freddy Kruger did you end up buying one? What was it like?
