Looking to pull the trigger on an 400-450 Upgrade but just need to decide who to go with .

Lateral say there Md321t cirmaic coated is the best option and scooby clinic are offering there SC42-46 option both turbos are about 2k . I also want headers ,injectors baffel sump fitting at the same time. Scooby clinic can do the lot and have given me a price, which i like the idea off. Not sure Lateral just sell the parts.

I have asked a few places to do the work like Cams Performance but not really getting any ware with them , i have been trying to get a price of them for about 8 weeks, maybe there just too busy or dont fancy the job.

Lateral have always been great to deal with. What Scoobyclinic say and do are two totally different things. They'll quote you a price but when you have to pay expect it to mysteriously increase.

Nelzsti

Hmm Very interesting thanks for the heads up

stockcar

no comparison between a relatively old design plain bearing turbo and a competition ball bearing upgraded core, etc used in the Lateral offerings..........

in the old days when the SC's were more reasonably priced then they did offer a value for money benefit but now at similar costs then we would always supply / use the Lateral variant

I originally planned to use an MD321T until I realised you need to modify the block and bell housing for it to fit. I then considered an SC turbo but they had no stock at the time. I ended up having one built be AET in the end, this was on my mechanics recommendation and I'm very happy with it. It's a GTX3071R with 11 blade billet wheel and 7cm housing. I make 458hp on pump fuel at 1.7bar. it spools really quickly which is what I wanted and the power is progressive, making the car easier to handle. I could have gone slightly larger for around 500hp but decided to keep lag to a minimum, it cost me about £1600.

Nelzsti

Is your a 2ltr Adam ?

Whe i was talking with Scooby clinic they said there SC 36 and 38 had one kind of internals and the sc42 had a Garret ball baring set up.

Think i will give AET a call

adam.pah

I'm on a 2.1 now. AET were really helpful. I just said I wanted something that would make 450hp with very minimal lag and this is what they made. My mechanic was trying to convince me to go with the bigger version but I'm glad I stuck to my guns and love the way the car drives now (it was much laggier before). It's easy to get caught up in the moment and push for more power.

Nelzsti

Just spoken to AET and ordered one , told them your spec on your GTX3071R with 11 blade billet wheel and 7cm housing , they said thats the dogs bollocks . They said £1770 including a fitting kit inc vat . So easy to deal with and they actually have the parts in stock !!!

adam.pah

That's great! I hope you're as happy with it as I am. They actually pushed my build through quickly too, took about 4 days to build and ship if I remember correctly.

Nelzsti

I am stock internals so was thinking to keep the power down to 420 430 ish will it still spool up nice you think?

I,m on the look out for injectors next , and headers. I have just bought a Process West top mount

adam.pah

I would think it'll still spool up just fine. On stock internals you probably want to keep boost to 1.5bar I'd say, although I'm sure your mapper will know best. I ran around 420 on standard internals without issues. I'm using RCM headers, fairly pricey but good quality. I'd also recommend a Harvey Smith trick up pipe to help it spool. AS performance can supply and they are cheap.

Where did you buy the PW top mount?

Nelzsti

Got it from Ghad performance second hand £400

Have you got any graphs after mapping in the new turbo? 450 is what I've been aiming for, stock internals in a new EJ207 short block. Currently using an old TD05 20g and it's only producing 380hp

adam.pah

This is how it's running now at 1.7 bar


This was a previous run at just under 1.6 bar but the car was awful to drive which is why I took it to a different mapper.

Just to clarify I can confirm that the SC42 is a Blouch Dominator 1.5XTR with a different housing (only available through SCR), These units do indeed use a Garret roller bearing core. The only major difference is that the Lateral units have a metal bearing carrier and the garret units use a plastic bearing carrier which are known to wear.

I had my SC42 rebuilt by Turbo Dynamics to have ceramic bearings and a metal bearing carrier, which saves weight overall and aids spool and turbo longevity.

NineOneSix

Looks amongst like my graph, but with more power and torque across the board 👌

Edit, looking at mine again, yours is just nicer end of 😂

adam.pah

The one obvious difference I noticed with my car compared to some of my mates who run similar power is how smooth it is. Even compared to my old SR40 unit, the power eases in rather than hitting you with everything at once, probably as it's spooling up nice and early. Makes it much more predictable and easier to drive fast. Don't get me wrong, it will still spin the wheels in 4th on a wet day though!

adam.pah

@NineOneSix If you wanted to definitely hit 450 on a 2.0 engine you could always go for the slightly larger GTX3076R. that would make the 450 figure for sure but the trade off is a bit more lag.

NineOneSix

Would the lag be worse than a tired TD05? 😅
